Full-automatic waste-free high quality blanking and edge rolling mold

Abstract

The embodiment of the invention discloses a full-automatic waste-free high quality blanking and edge rolling mold. The mold comprises an upper mold plate, a lower mold plate, a forming upper mold, a forming lower mold and a forming mandril, wherein the forming upper mold is mounted on the upper mold plate, the forming lower mold is mounted on the lower mold plate, the forming mandril is cylindrical, the forming upper mold is provided with a semi-cylindrical upper forming concave surface, the forming lower mold is provided with a semi-cylindrical lower forming concave surface, the forming mandril is cylindrical, the forming upper mold is arranged above the forming lower mold, the forming mandril is placed between the forming upper mold and the forming lower mold, and a protruding baffle block is also arranged at the lowest part of the center of the lower forming concave surface. According to the embodiment of the invention, no wastes are generated; blanking and unloading and edge rolling can be finished with only one stroke of a press, so that the efficiency is higher; formed workpieces are ejected automatically and are full-automatic from the feeding process to the discharging process; the baffle block is arranged to overcome the shrinking resilient stress during tension leveling, so that the full-automatic waste-free high quality blanking and edge rolling mold is smaller in resilience and higher in precision.

Description

technical field [0001] The invention relates to the field of rolling dies, in particular to a fully automatic, waste-free, high-quality punching and rolling die. Background technique [0002] Circular workpieces are widely used in production. They are widely used in motor housings, bearing housings, and auto parts housings. At present, the processing of circular workpieces is divided into several situations: [0003] After the plate is cut, it is subjected to multiple bending processes to make the plate cylindrical; this processing method requires multiple sets of bending dies and blanking dies, which is costly and inefficient. [0004] After the plate is unloaded, it is rolled into a circle by the plate rolling machine, so that the plate is cylindrical; the processing continuity of the plate rolling machine is poor, the average processing time of a single workpiece is longer, and the efficiency is very low. [0005] However, the current existing one-time rolling mold has t...

AI Technical Summary

Problems solved by technology

[0003] After the plate is cut, it is bent many times to make the plate cylindrical; this processing method requires multiple sets of bending dies and blanking dies, which is costly and inefficient

[0004] After the plate is unloaded, it is rolled into a circle by the plate rolling machine, so that the plate is cylindrical; the processing continuity of the plate rolling machine is poor, the average processing time of a single workpiece is longer, and the efficiency is very low

[0005] However, the existing one-time round forming molds have disadvantages such as large springback, low processing progress, and difficult demoulding.
