AI Technical Summary

Technical Problem

In existing technologies, products are prone to deformation after the drawing and flanging processes due to uneven material flow or springback, which necessitates secondary processing and increases production costs.

Method used

A flanging device is designed, comprising an upper mold and a lower mold. Pressure blocks and side pressure blocks are set on the molds. The slider assembly is driven to reciprocate between the separation position and the forming position through the guide surface. The first side forming surface and the second side forming surface are used to shape the side of the product to be processed, so as to avoid uneven material flow or springback.

Benefits of technology

This technology enables simultaneous forming of the front and sides of the product to be processed, reducing the need for secondary processing, saving development costs and production cycle time, and improving production efficiency.

Abstract

This utility model provides a flanging device for product flanging, comprising: an upper mold and a lower mold. The upper mold is provided with an adjacent pressure block and a side pressure block. The side pressure block has a first guide surface on the side facing the pressure block, and a first side forming surface on the side of the pressure block near the side pressure block. The lower mold is provided with an adjacent flanging part and a slider assembly. The slider assembly has a second guide surface on the side away from the flanging part, and a second side forming surface on the side of the slider assembly near the flanging part. The side pressure block drives the slider assembly to reciprocate between a separation position and a forming position through the first guide surface and the second guide surface. The beneficial effects of this utility model include at least the following: when the upper mold is driven to move downward, the pressure block contacts the flanging part to form the product to be processed, and the first side forming surface and the second side forming surface shape the side of the product to be processed, thereby simultaneously achieving the front forming and side shaping of the product to be processed.
