AI Technical Summary
In existing stamping dies, the clamping blocks are displaced downwards under pressure during die closing, causing deformation of the fixing frame and affecting stamping accuracy.
The system employs a support assembly and a clamping plate structure. The support platform is connected to the support plate via a guide plate to counteract the downward displacement tendency of the clamping block. The clamping plate and positioning groove work together to restrict the vertical movement of the clamping block. Combined with the lifting assembly and hydraulic cylinder, it provides stable support.
This reduces the deformation of the fixing frame caused by the clamping block under stress, and improves the alignment accuracy of the upper and lower molds and the overall structural stability of the mold.
