1. Optimize mold design
Reasonable mold gap: Ensure that the gap between the male and female molds is reasonable to avoid deformation caused by too large or too small gaps.
Add a pressure plate: Add a pressure plate to the mold structure to make the plate contact the plane of the pressure plate and apply a certain pressure to prevent deformation.
Mold edge trimming: Regularly check the die edge, and trim it in time when the reverse taper is found to ensure that the edge is sharp.
2. Adjust stamping process parameters
Punching force and speed: According to the material characteristics and the shape of the metal stamping parts, reasonably adjust the punching force and punching speed to reduce deformation.
Punching temperature: Control the temperature change during the stamping process to avoid deformation caused by too high or too low temperature.
Lubricant selection: Use appropriate lubricants to reduce friction and heat and reduce the risk of deformation.
3. Material selection and pretreatment
Select suitable materials: According to the use environment and requirements of metal stamping parts, select materials with stable mechanical properties and small rebound.
Material pretreatment: Pre-treat the material by annealing, etc. to soften the material, improve plasticity and reduce deformation.
4. Strengthen production management and quality control
Regular mold maintenance: Regularly clean the dirt in the mold cavity, grind the worn mold edge, and keep the mold in good condition.
Strict quality control: Strictly check the size, shape and surface quality of metal stamping parts to ensure that the product is qualified.
Employee training: Strengthen employee training on stamping process and mold structure to improve operating skills and quality awareness.
Solving the deformation problem of metal stamping parts requires starting from mold design, stamping process parameters, material selection and pretreatment, production management and quality control, etc. Only through comprehensive measures can deformation be effectively reduced and product quality can be improved.
