CNC Multifunctional Metal Tensioner

Abstract

The patent of the invention belongs to the technical field of metal cold drawing forming. It is a kind of mechanical equipment that can stretch metal plates and special-shaped materials to the yield limit of materials, and force them to fit and form three-dimensional molds through multi-dimensional movement, flipping, and twisting. . The equipment consists of three working platforms: left, middle and right. There is an independent four-axis stretching unit on each of the left and right platforms. The jaws with tightening devices on the unit are driven by the hydraulic system to realize X, Y, Z three-way displacement movement and rotation movement. The left and right platforms are equipped with guide rails, chains, pin holes, etc. to fix the unit, and realize the self-propelled unit on the platform through the driving device to meet the needs of stretching workpieces of different lengths. There is a T-shaped groove on the surface of the middle platform to fix the mold, and a hydraulic drive device is installed on the bottom, which can realize lifting and turning back and forth, and cooperate with the left and right four-axis motion units. Axis linkage tensioning.

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
