Workholding Measures to Prevent Deformation in Spinning Processing There are many factors that can affect the spinning process, and the occurrence of these factors can lead to the production of defective or scrap products during the spinning process. Therefore, it is essential to ensure the quality of the spinning process in order to better guarantee the use of the product During the spinning process, it is necessary to control the key processing techniques and adopt reasonable anti deformation clamping techniques to reduce or avoid dimensional accuracy errors and surface quality losses caused by clamping deformation of the spun parts; Reduce the impact of cutting force on deformation. According to the specific structure of the spun parts, different process measures and methods can be used to meet the design and manufacturing requirements of similar spinning parts. The workholding measures to prevent deformation in spinning processing include: (1) Control heating temperature and speed: Reasonably select heating temperature and control heating speed. For complex molds, balanced heating methods such as slow heating and preheating can be used to reduce deformation during heat treatment. (2) Increase the contact area between the workpiece and the chuck: reduce the deformation of the workpiece during workpiece clamping by increasing the contact area, such as using elastic pressure plates. (3) Using axial clamping force: Design and manufacture specialized chucks to apply clamping force on the end face, solving bending deformation caused by thin workpiece walls and poor rigidity. (4) Optimize machining process: Control machining parameters, use sharp and wear-resistant cutting tools, perform cooling treatment to remove heat and reduce cutting stress. (5) Develop a reasonable processing plan: Analyze workpiece processing requirements with technical personnel, familiarize with product drawings, develop a reasonable processing plan, and make timely improvements. (6) Reasonably design the workpiece: clarify the material, economy, performance, toughness, and strength of the workpiece, select suitable processing materials, and perform necessary heat treatment to avoid deformation. Through the above measures, deformation problems in spinning processing can be effectively reduced, and the accuracy and quality of products can be improved.
