Numerical-control multifunctional metal stretching and drawing machine

Abstract

The invention belongs to the field of metal cold drawing forming technologies, and discloses mechanical equipment. Metal plates, special-shaped materials and the like can be forced by the mechanical equipment to cling to three-dimensional dies to be shaped by the three-dimensional dies by means of multi-dimensional movement, turnover and twisting after the metal plates, the special-shaped materials and the like are stretched to reach yield limit. The mechanical equipment comprises a left working platform, a middle working platform and a right working platform. Two independent four-axis stretching units are respectively arranged on the left working platform and the right working platform, and jaws with tightening devices on the units can be driven by hydraulic systems to carry out X-direction, Y-direction and Z-direction displacement movement and rotation movement. Guide rails, chains and the like are arranged on the left working platform and the right working platform, pin holes and the like are formed in the left working platform and the right working platform, the guide rails, the chains, the pin holes and the like are used for fixing the units, and the units can automatically travel on the platforms by the aid of driving devices, so that requirements on stretching workpieces with different lengths can be met. A T-shaped groove is formed in the surface of the middle working platform and is used for fixing the dies, a hydraulic driving device is arranged below the middle working platform, lifting and front-back turnover movement can be carried out, the hydraulic driving device is matched with a left four-axis movement unit and a right four-axis movement unit, and ten-axis linkage stretching and drawing effects can be realized under instruction operation actions of a hardware control system.

Description

technical field [0001] The invention belongs to the technical field of cold drawing of metal materials, and mainly provides a method that can stretch metal materials such as metal plates, special-shaped plates, and pipes to their yield strength according to their different characteristics, and then force them through multi-dimensional movements such as displacement, rotation, and twisting. Cold drawing equipment that is positioned and formed according to specific tooling fixtures. Background technique [0002] With the improvement of my country's industrialization level, and the continuous improvement of product quality and process requirements in the field of large-scale equipment manufacturing such as aviation equipment, high-speed rail, launch vehicles, missiles, and ships, more and more products are in the selection of skeleton and skin materials. , using various new synthetic metal materials with higher strength and lighter weight. At the same time, in order to make the...

AI Technical Summary

Problems solved by technology

However, the current traditional stamping and roll bending technology and equipment cannot achieve multi-dimensional stretching, displacement, twisting and other multi-dimensional stretching of these special-shaped materials and plates according to product design requirements, and finally achieve a perfect fit with 3D tooling fixtures. Components such as beams and skins can only be made by hand, the production efficiency is low, and the product quality is difficult to control, which seriously restricts the development of my country in the field of large-scale equipment manufacturing
