1. Select the appropriate materials and tools (1) Material selection: end point machine shell processing According to the design requirements and use environment of end point machine shell, select the appropriate material. The material should have good plasticity and toughness to reduce the stress concentration and deformation generated during the bending process. 2) Tool selection: Use the appropriate bending die and tools to ensure the accuracy and durability of the die. The gap, angle and shape of the die should match the processing requirements to reduce the machining error and deformation. II. Optimize the processing technology (1) Control the bending speed: end point machine shell processing In the bending process, the bending speed should be properly controlled to avoid the deformation caused by too fast or too slow. A faster bending speed may cause the internal stress of the material to be deformed before it is released, and a too slow speed may increase the processing time and reduce the efficiency. (2) Adjust the bending angle and strength: Reasonably adjust the bending angle and strength according to the thickness and hardness of the material. Too large an angle or too much force may cause the material to produce excessive stress concentration at the bend, which can cause deformation. (3) Preheating treatment: For some materials that are easily deformed, the end point machine shell processing can be preheated before bending. Preheating can soften the material and reduce its deformation resistance, so that it is easier to achieve the desired shape and size during the bending process. III. Strengthen quality control and testing (1) Strengthen process monitoring: end point machine shell processing During the bending process, the monitoring and inspection of the processing process should be strengthened. Timely detection and correction of problems in processing, such as mold wear, material deviation, etc., to prevent the occurrence of deformation. (2) Implement quality inspection: end point machine shell processing conducts quality inspection on the processed shell, including dimensional accuracy, shape accuracy and surface quality. Through testing, products with deformation can be found and eliminated to ensure that the product quality meets the requirements. IV. Other precautions (1) Avoid material rebound: end point machine shell processing During the bending process, the material may rebound due to plastic deformation. In order to avoid the deformation caused by springback, sufficient simulation and testing can be carried out before processing to determine the appropriate bending process parameters. Consider the physical characteristics of the material: the physical characteristics of different materials (such as elastic modulus, yield strength, etc.) are different, and the deformation effect during processing is also different. Therefore, when selecting materials and formulating processing techniques, the physical characteristics of materials should be fully considered.
