Punching machining is a common metal processing method that uses dies to impact and cut metal materials to obtain the desired shape and size. In punching and cutting processing, there are some important precautions that need to be followed to ensure processing quality and work safety. The following will provide a detailed introduction to the precautions for punching and cutting processing.

1. Safe operation

Punching processing involves the use of mechanical equipment and cutting tools, therefore strict safety regulations must be followed during the operation process. Operators should undergo professional training, understand the operating procedures of the equipment, and wear safety protective equipment such as gloves, goggles, etc. At the same time, the operating status of the equipment should be regularly checked to ensure its safety and reliability. When working, it is important to avoid placing hands or other body parts near the tool to avoid accidents.

2. Material selection

When conducting punching and cutting processing, suitable metal materials should be selected based on specific material requirements. The hardness, strength, and toughness of materials can all have an impact on the effectiveness of offset cutting. Therefore, when selecting materials, it is necessary to fully consider the usage environment and requirements after processing, and select appropriate materials based on the required shape and size. In addition, the thickness of the material also needs to be determined based on the ability of the punching equipment to avoid the inability of excessively thick materials to complete punching.

3. Mold design

Punching machining requires the use of stamping dies to impact and cut materials, so the design of molds is an important part of punching machining. In mold design, it is necessary to ensure the stiffness and stability of the mold to ensure the accuracy and quality of processing. At the same time, the design of the mold should fully consider factors such as material deformation and settlement, and take corresponding measures to solve these problems. In addition, the surface of the mold needs to undergo sufficient smoothness treatment to ensure the appearance quality of the processed product.

4. Punching sequence

When conducting multi pass punching machining, it is necessary to arrange the punching sequence reasonably to greatly improve machining efficiency and quality. Generally speaking, internal punching is performed first, followed by external punching. In addition, it is also important to pay attention to the clear and clear order of punching to avoid incorrect operations and machining confusion.

5. Cut design

The notch design in punching machining is one of the key factors affecting machining quality. The design of the incision should fully consider the properties of the material to avoid material rupture and deformation. The shape and size of the incision should meet the design requirements of the product, and take into account the subsequent processing and assembly requirements. In addition, attention should also be paid to the flatness and surface roughness of the incision to achieve better machining quality.

6. Control of punching speed and force

The speed and force of punching machining are important factors that affect the machining results. Excessive cutting speed may lead to material deformation and fracture, while excessive speed can reduce production efficiency. Therefore, in the processing process, it is necessary to choose an appropriate punching speed based on the properties of the material and processing requirements. At the same time, it is necessary to control the punching force to avoid excessive force causing equipment damage or product deformation.

7. Treatment after punching and cutting processing

After punching and cutting, the size and shape of the product may change, requiring subsequent trimming and treatment. Pay attention to maintaining production during the repair process
