Die drawing and flanging mechanism

Abstract

The invention discloses a die drawing and flanging mechanism. The mechanism comprises a servo motor, a bearing seat, a first bearing, a ball screw assembly, a second bearing, a die drawing rod, chromium-plated shafts, a U-shaped bearing, an eccentric shaft, an inductor, a self-lubricating copper sleeve, a coupler and a limiting sleeve, wherein the servo motor is connected with the ball screw assembly through the coupler, the ball screw assembly is connected with the die drawing rod through the coupler, and the die drawing rod is connected with a die; and the first bearing is arranged at the output end of the servo motor, the first bearing is connected with the second bearing through the ball screw assembly, the chromium-plated shafts are arranged at two sides inside the die, and the U-shaped bearing and the eccentric shaft are arranged on the ball screw assembly. Compared with a traditional die drawing structure, the die drawing and flanging mechanism is more flexible, can be used forperforming layered flanging on long and short edges, and is the premise of rapid die changing.

Description

technical field [0001] The invention relates to the technical field of drawing dies, in particular to a drawing die folding mechanism. Background technique [0002] Stretching refers to a method of aligning the polymer chains in the polymer along the direction of the external force, thereby improving the structure and mechanical properties of the polymer. Stretching can be divided into two types: uniaxial stretching and biaxial stretching. The former aligns the chains in one direction, while the latter aligns the chains in a plane. Generally, two sets of stretching and hemming are used to make similar products. mold, and the concentricity of the product is poor, and the movement stroke of the machine tool is required to be large, so the production efficiency is not high, and the rate of defective products is high. Contents of the invention [0003] The object of the present invention is to provide a drawing die folding mechanism to solve the problems raised in the above-m...
