Stamping die for hoop forming

Abstract

The invention discloses a stamping die for hoop forming, and relates to the technical field of mechanical forming. The stamping die comprises a base plate, a female die and a male die, wherein the female die comprises a pair of half-shaped dies which are oppositely arranged, and the lower parts of the half-shaped dies are rotatably connected to the upper surface of the base plate through rotatingshafts; the male die is arranged right above the female die; a pair of mounting grooves are symmetrically formed in the upper surface of the base plate, the two mounting grooves are in a one-to-one correspondence to the two half-shaped dies, elastic sheets are arranged in the mounting grooves, and the elastic sheets are connected with the lower parts of the half-shaped dies; and supporting columnsare vertically arranged on the opposite sides of the female die, the upper ends of the two supporting columns are connected through an undertaking frame, and the undertaking frame is provided with apositioning component used for limiting the position of a piece to be pressed. The stamping die not only has simple and reasonable structural design and convenient use, but also effectively improves the forming effect and stamping efficiency of the piece to be pressed, and has higher market application value.

Description

technical field [0001] The invention belongs to the technical field of mechanical forming, and in particular relates to a stamping die for hoop forming. Background technique [0002] A hoop is a component that hugs or hoops another material with one material. It belongs to a fastener and has a wide range of applications in industry. The arc-bent shape of the hoop is mainly determined by the mold. The design specifications of the hoop die and the materials selected directly affect the product quality of the hoop from the die. Most of the existing hoops are semi-circular, and the hoop press mold usually adopts a concave die and a punch corresponding to the radian, and the flat iron is bent into the required shape by mutual punching of the upper die and the lower die. [0003] However, some existing hoops with special shapes, such as U-shaped hoops with an opening gap smaller than the width, will be stuck on the punch after stamping and forming, and need to be removed manually...

Problems solved by technology

[0003] However, some existing hoops with special shapes, such as U-shaped hoops with an opening gap smaller than the width, will be stuck on the punch after stamping and forming, and need to be removed manually, and the production efficiency is low; When the pressed piece is pressed into the die, the piece to be pressed may be twisted, resulting in stamping failure
