A stretch forming device for a metal mold

Abstract

The invention relates to the technical field of industrial manufacturing, and discloses a stretch forming device of a hardware die. The stretch forming device comprises a die stretching workbench, andthe top of the die stretching workbench is fixedly provided with a fixed supporting plate. According to the stretch forming device of the hardware die, the hardware die needing to be stretched is placed between a left clamping plate and a right clamping plate between an upper fixing plate and a lower fixing plate, spring supporting rods are pressed, and then the spring supporting rods are rotated, so that clamping plates arranged on the outer side surfaced of the spring supporting rods are rotated to the interiors of limiting grooves, then looseness between the left clamping plate and the right clamping plate is avoided, and then the hardware die between the left clamping plate and the right clamping plate is fixed and clamped; and the design that an extending rod is inserted into an extending hole is combined, so that a supporting rod is close to the die stretching workbench, then the lower fixing plate on the outer side face of the supporting rod is clamped with a clamping plate, the upper fixing plate at the top of the lower fixing plate is fixed to inserting rods in an inserted mode, and then the purpose of carrying out stretch forming on the hardware die by using the hydraulic stretching device is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial manufacturing, in particular to a stretch forming device for a metal mold. Background technique [0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals including gold, silver, copper, iron, and tin. After manual processing, they can be made into works of art or metal devices such as knives and swords. Hardware in modern society is more extensive. , such as hardware tools, hardware parts, daily hardware, construction hardware and security supplies, etc. Most of the small hardware products are not final consumer goods. [0003] Hardware parts are mostly used to fix things, process things, decorate, etc. The casting of hardware parts is cast by melting the hardware and pouring it into the interior of the hardware mold. The hardware model is formed by stretching. At present, the existing hardware mold Stretch molding devices, when stretching metal mol...
