Classification of commonly used press brake tooling:

There are several types of bending tools, including L-shaped, R-shaped, U-shaped, Z-shaped, etc. The upper punch mainly has different angles such as 90 °, 88 °, 45 °, 30 °, 20 °, and 15 °. There are double and single slots with different slot widths of 4-18V in the lower dies, as well as R lower mold, acute angle lower mold, flattening tool set, etc. press brake tooling punch and die are divided into sections and whole parts: the upper punch is generally divided into sections of 300mm, 200mm, 100mm, 100mm, 50mm, 40mm, 20mm, 15mm, 10mm, and the whole is 835mm. The lower die is generally divided into sections of 400mm, 200mm, 100mm, 50mm, 40mm, 20mm, 15mm, and 10mm, and the whole is 835mm.

① Bending tools are made of steel that has undergone special heat treatment, and have the characteristics of high hardness, low wear, and high pressure resistance. However, each set of molds has its maximum pressure capacity: tons/meter. Therefore, when using the mold, the length of the mold should be selected, that is, how much pressure should be added per meter, and it must not exceed the pressure marked by the mold.

② In order to avoid damaging the mold, we have stipulated that when aligning the origin, upper and lower molds with a length of at least 300mm must be used to align the origin Only after aligning the origin can the upper and lower molds of the same height be used. It is strictly prohibited to use split molds for the origin, and the origin must be based on the internal origin pressure of the AMADA machine.

③ When using molds, due to the different heights of various molds, only molds of the same height can be used when selecting molds on a machine, and molds of different heights cannot be used.

④ When using molds, appropriate upper and lower molds should be selected based on the hardness, thickness, and length of the metal sheet material. Generally, the lower mold is used according to the standard of 5-6T, and the length should be longer than the sheet material. When the material is harder and thicker, a lower mold with a wider groove should be used.

⑤ When bending sharp angles or pressing dead angles, a 30 degree angle should be selected, with the sharp angle bent first and the edge pressed dead later. When bending the R angle, the R upper mold and R lower mold should be selected.

⑥ When bending longer workpieces, do not use segmented molds to reduce tool indentation, and choose single groove ones because the outer angle R of the V-groove of the lower mold of the single groove is large, which is not easy to produce bending indentation.

⑦ When selecting the upper mold, we should understand the parameters of all molds and decide which upper mold to use based on the shape of the product to be formed.

⑧ When bending products with extremely hard hardness or thick sheet metal, it is not allowed to use molds to bend steel bars or other cylindrical products.

⑨ When using molds, one should have a clear mind and lock the upper and lower molds after the machine has aligned with the origin. Do not let the molds fall off, injure people or damage the molds. During the operation, be careful not to apply too much pressure at once and pay attention to changes in the displayed data on the screen.

⑩ After using the tools, it should be promptly returned to the tools storage cabinets rack and placed according to the markings. The dust on the mold should be regularly cleaned and rust proof oil should be applied to prevent rusting and reduce the accuracy of the mold.

The schematic diagram of the shape of the upper punch type is mainly used for processing angles greater than or equal to 90 with a straight knife as shown in the following figure, and for processing angles greater than or equal to 90 with a curved knife as shown in the following figure. For processing angles greater than or equal to 30 with a sharp knife as shown in the following figure

The schematic diagram of the shape of the lower die type is mainly used. Note that the single V lower mold is shown in the following figure. 1. When the V-shaped angle is 86 (reference value), angles greater than or equal to 90 can be processed. 2. When the V-shaped angle is 30 (reference value), angles greater than 30 can be processed. The lower mold used for the quick bending machine is of this type. The double V lower mold is shown in the following figure. The lower mold used for AMADA bending machine is of this type

Segmentation of bending tools:

Under normal circumstances, the length of the tool is 835mm; to facilitate bending different lengths, the entire length of the tool is often divided into the following sections: 10+15+20+40+50+100+100+200+300=835

The correspondence between plate thickness and groove width:

Normally, the slot width is 6 times the thickness of the board. The comparison table of plate thickness and groove width currently specified by Wan Jiayuan is as follows: Material thickness (mm) 1.01.21.52.02.5 Bending machine lower die width (mm) 6681216

The minimum bendable size for processing according to the comparison table above (including plate thickness):

Plate thickness (mm) 1.01.21.52.0L minimum size for L-shaped bending (mm) 4.54.768.5Z minimum size for Z-shaped bending (mm) 77.4912

 

Conventional bending sequence:

1. Short side first and then long side: Generally speaking, when all four sides are bent, folding the short side first and then the long side is beneficial for the processing of the workpiece and the assembly of the bending mold

2. First the periphery and then the middle: Normally, it is folded from the periphery of the workpiece to the center of the workpiece

3. Partial first and then overall: If there are some structures inside or outside the workpiece that are different from other bends, it is generally necessary to bend these structures first and then bend other parts

4. Consider interference situations and arrange the bending sequence reasonably: The bending sequence is not fixed, and the processing sequence should be adjusted appropriately according to the shape of the bending or obstacles on the workpiece

 

 

A pressure gauge, commonly referred to as a spring tube pressure gauge or analog pressure gauge, consists of a measuring system made up of a connection, a spring tube, and a transmission mechanism. When the measured pressure changes, the free end of the spring tube moves, and the corresponding pressure value is indicated on the dial. The pointer shows the pressure reading by pointing to the corresponding scale. Pressure gauges are typically used to measure the working pressure of liquids, steam, gas, or other media in closed systems.

When selecting a pressure gauge, it is important to take into account various factors such as the application environment, readability, medium characteristics, and installation method.

Below are the key parameters to consider:

1. Measuring Medium – Name, Operating Temperature, and Characteristics
Clearly identify the medium to be measured, along with its temperature and any special properties (e.g., corrosivity, viscosity, or presence of particulates).

2. Dial Diameter
The choice of dial size depends not only on readability from a distance and ease of observation but also on whether the installation location can accommodate the selected size.

3. Pressure Range
The range should be selected based on actual working pressure and safety requirements. Typically, the full-scale range should be 1.5 to 2 times the normal working pressure.

4. Body Material Selection
Select the appropriate gauge material according to the properties of the measured medium and the conditions of the installation environment.

5. Installation Type and Dimensions
Consider the mounting method and connection dimensions to ensure proper installation,e.g Diaphragm pressure gaue.

6. Dial and Connection Orientation
Choose from the following configurations depending on application needs: Radial, radial with flange, axial without flange, or axial with flange.

7. Functional Requirements
Determine whether additional functions are needed, such as control capabilities, remote transmission, vibration resistance, etc.

By carefully evaluating these parameters, you can select a pressure gauge that ensures accurate measurement, operational safety, and long-term reliability in your specific application.

Is your order picking process slowed down by reaching, searching, and shuffling boxes? Do you struggle with inventory rotation, leading to expired stock? It’s time to replace static storage with dynamic movement. Carton Flow Racking isn't just shelving; it's a gravity-powered logistics system designed for speed and accuracy.

What is Carton Flow Racking and How Does It Work?

Carton flow racking is a high-density, dynamic storage system where boxes or cases glide on rolling tracks from the loading point at the rear to the picking face at the front. It turns traditional shelving into a first-in, first-out (FIFO) conveyor system powered by gravity.

The principle is elegantly simple and highly effective:

Gravity-Powered Movement: Each shelf lane is inclined and fitted with low-friction wheel or roller tracks. When a carton is loaded into the back of a lane, gravity gently pulls it forward.

Automatic Product Rotation: As the front carton is picked, the next one immediately rolls into position. This guarantees perfect FIFO inventory rotation, eliminating the risk of stock becoming obsolete at the back of a deep shelf.

High-Density Storage: The system allows for deep lane storage (often 5-10 cartons deep) while maintaining instant access to the front item. This dramatically increases storage density compared to single-depth shelving and reduces the aisle space required.

Where Is Carton Flow Racking the Ideal Solution?

This system revolutionizes operations in any environment with a high volume of case-picking for fast-moving goods. It is the gold standard for:

E-commerce & Retail Distribution Centers: Perfect for picking individual SKUs for direct-to-consumer orders or store replenishment.

Pharmaceutical & Medical Supply Warehouses: Ensures strict FIFO rotation for products with expiration dates or lot tracking requirements.

Cosmetics & Consumer Goods Logistics: Ideal for handling a vast number of SKUs in standard-sized cartons.

Food & Beverage Distribution: Excellent for managing perishable goods and high-turnover packaged products.

Assembly Line Kitting & Parts Supply: Keeps components organized and automatically presented to assembly workers.

In the world of high-speed manufacturing, whether you are processing seafood, printing packaging, or recycling plastic, your blades are the heartbeat of your production line. A dull or incorrectly selected blade doesn't just produce poor-quality cuts—it causes machine downtime, increased waste, and skyrocketing maintenance costs. At Ma'anshan Guangchuan, we understand that the right blade is an investment in efficiency. In this guide, we share professional insights on how to choose the perfect blade for your application.

 

1. Match the Material to Your Application

The first step in blade selection is understanding the material being cut.

• Food Processing: For products like shrimp deveining or meat dicing, stainless steel with high corrosion resistance is essential to meet food safety standards.

• Abrasive Materials: When shredding waste or recycling rubber, tools require high-impact alloy steel or tungsten carbide to withstand extreme wear.

• Paper & Film: Slitting applications require high-speed steel (HSS) to maintain a razor-sharp edge over millions of rotations.

 

2. Consider the Hardness (HRC) Balance

Hardness is a double-edged sword. While a harder blade (higher HRC) stays sharp longer, it also becomes more brittle.

• High Hardness: Best for thin films and soft materials to ensure clean, burr-free edges.

• Balanced Toughness: Essential for heavy-duty shearing or shredding where the blade must absorb impact without chipping.

 

3. Precision Matters: The Role of CNC Grinding

A blade is only as good as its finish. Using advanced CNC grinding machines, such as the MKP7140 used in our facility, ensures micron-level flatness and edge consistency. A smoother surface finish reduces friction and heat buildup, which are the primary enemies of blade longevity.

 

4. Geometry and Edge Angle

The "bevel" or angle of the blade edge significantly impacts performance.

• Acute Angles: Provide the cleanest cuts but are more delicate.

• Large Angles: Offer more support behind the edge, making them ideal for heavy-duty metal shearing or wood chipping.

 

5. Professional Packaging and Anti-Rust Protection

Often overlooked, how a blade is stored and shipped affects its initial performance. High-precision tools should arrive in reinforced, sea-worthy wooden crates with anti-rust oil application. At Guangchuan, we utilize heavy-duty wooden crate packaging to ensure your precision edges remain pristine during global transit.

 

Choosing the right industrial blade is a balance of material science, precision engineering, and application knowledge. By investing in quality tools, you reduce the "Total Cost of Ownership" by minimizing blade changes and maximizing output.

In a VFD (Variable Frequency Drive) control system utilizing Siemens automation components, the modules 6GK7342-5DA02-0XE0 and 6ES7153-4AA01-0XB0 serve distinctly different functions, and whether they are both required depends entirely on your system architecture.

 

 Do You Need Both?

Typically, you do not need both modules simultaneously for a standard application, as they operate in different network domains and physical locations .

- 6GK7342-5DA02-0XE0 (CP 342-5): This is a Communications Processor (CP) designed for the S7-300 PLC rack. Its primary role is to connect the central PLC controller to a PROFIBUS DP network . In a VFD system, you would use this module if your drives are connected via PROFIBUS and you need the central PLC to master the network and exchange data with the drives .

- 6ES7153-4AA01-0XB0 (IM 153-4 PN): This is an Interface Module (IM) for an ET 200M distributed I/O station . Its role is to connect remote I/O modules (mounted on a separate sub-rack) back to the central PLC via a PROFINET network . You would use this if your VFD system requires local sensors/actuators to be wired to a remote cabinet away from the main PLC.

 

 Key Functions：

- CP 342-5 (PROFIBUS DP): Acts as the master or slave on a PROFIBUS network. It handles communication with drives, HMIs, or other field devices, offloading this task from the CPU .

- IM 153-4 PN (PROFINET IO): Acts as the gateway for an ET 200M remote I/O rack. It allows standard S7-300 I/O modules to be placed remotely and communicate with the controller over an industrial Ethernet (PROFINET) network .

 Critical Usage Considerations

1.  Network Architecture: Do not confuse their purposes. A CP 342-5 is for the central controller rack; an IM 153-4 is for a remote I/O rack. Using them together would imply a complex system with both PROFIBUS drives and remote PROFINET I/O.

2.  Product Lifecycle: Note that the specific model 6ES7153-4AA01-0XB0 has been announced for discontinuation (as of October 2023) . Verify the current status or consider successors for new designs.

3.  Installation & Safety: Both modules are sensitive to electrostatic discharge . Ensure proper grounding of the mounting rail . Always disconnect power before installation and maintain adequate clearance (at least 40mm) around modules for ventilation .
