Novel high-precision U-shaped bending die

Abstract

The invention relates to a novel high-precision U-shaped bending die. The bending die comprises an upper die base (1), a lower die base (2), a die shank (3), a plurality of guide pillars (4), a male die (5), a female die (6) and a discharge mechanism, wherein the lower ends of the guide pillars (4) are fixed to the lower die base (2) and perpendicular to the end face of the lower die base (2), the upper portions of the guide pillars (4) are matched with the upper die base (1), the male die (5) is fixedly installed in the middle of the lower side of a male die fixing plate (7), the die shank (3) penetrates through the upper die base (1) to be fixed to the male die (5) and is coaxial with the male die (5), the female die (6) is fixed above the lower die base (2) and aligns with the male die (5), and the discharge mechanism comprises a fixed discharge plate (9), a discharge bolt (13) and a discharge block (14). The bending die has the advantages that the bending die is long in service life, low in maintenance cost and high in bending and forming precision, and workpieces can be taken out easily.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a novel high-precision U-shaped bending mold. Background technique [0002] Since the reform and opening up, with the rapid development of the national economy, the market demand for molds has continued to grow. In recent years, the mold industry has been developing rapidly at a growth rate of about 15%, and the ownership of the mold industry has also undergone tremendous changes. In addition to state-owned professional mold factories, collectives, joint ventures, sole proprietorships and private companies have also developed rapidly. In recent years, many mold companies have increased investment in technological progress, and regard technological progress as an important driving force for enterprise development. Some domestic mold companies have popularized two-dimensional CAD, and have begun to use international general software such as UG, Pro / Engineer, I-DEAS, and Euclid-IS. ...

AI Technical Summary

Problems solved by technology

On the one hand, during use, there is a relative displacement between the guide post and the upper mold base. After long-term use, the upper mold base is severely worn, and its working accuracy cannot be guaranteed. The manufacturing cost of the upper mold base is high, and the replacement is time-consuming and laborious; On the other hand, after the die and the punch cooperate to bend the workpiece, the workpiece is embedded in the die and is not easy to take out.
