Extrusion molding structure using multiple cylinders

Abstract

The invention discloses a structure for conduction extrusion forming through multiple air cylinders. A first air cylinder and a second air cylinder are arranged outside a supporting frame, and a firstguide mechanism and a second guide mechanism which are parallel to each other are arranged in a cavity of the supporting frame; the first guide mechanism is sleeved with a first mounting plate, a second mounting plate and a third mounting plate, and a fourth mounting plate is arranged between the first mounting plate and the second mounting plate; a third air cylinder is arranged between the fourth mounting plate and the first mounting plate, and a groove is formed in the fourth mounting plate is an inwards sunken mode; a first forming tool is arranged between the second mounting plate and the third mounting plate, and a third guide mechanism is arranged on the second mounting plate; a fourth guide mechanism is fixed to the end of the third guide mechanism and penetrates through the fourth mounting plate, and a limiting table is fixed to the end of the fourth guide mechanism; and a second forming tool is arranged between the second mounting plate and the third mounting plate. According to the structure for conduction extrusion forming through the multiple air cylinders, elasticity of a raw material is eliminated by achieving a plurality of times of extrusion forming through the multiple air cylinders so that after extrusion forming, the quality cannot be affected due to rebound, and the quality of extrusion forming meets the requirement accordingly.

Description

technical field [0001] The invention relates to a mechanical forming tool, in particular to a structure which adopts multi-cylinders for extrusion forming. Background technique [0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The working fluid converts heat energy into mechanical energy through expansion in the cylinder of the engine; the gas is compressed by the piston in the cylinder of the compressor to increase the pressure. The casings of turbines, rotary piston engines, etc. are often also referred to as "cylinders". The thrust and pull forces on the piston rod are determined according to the force required for the work. Therefore, when selecting the cylinder, the output force of the cylinder should have a slight margin. If the cylinder diameter is too small, the output force will not be enough, and the cylinder will not work normally; but if the cylinder diameter is too large, it will n...

AI Technical Summary

Problems solved by technology

In mechanical molding, it is necessary to use thrust to realize extrusion molding, but the traditional mechanical molding is one-time push molding, and this method is easy to rebound after extrusion molding due to the elasticity of the raw material itself, which will damage the quality of the molding. less than molding requirements
