Cold drawing numerical control rolling forming machine based on PLC

Abstract

The invention relates to the technical field of rolling forming, in particular to a cold drawing numerical control rolling forming machine based on a PLC. A working frame is installed at an output port of a forming machine body, a sliding rail is installed on the working frame, a sliding block can slide on the sliding rail and is controlled by an air cylinder connected with the PLC end of the forming machine body to slide on the sliding rail, the installation seat is installed on the sliding block and moves along with the sliding block, two auxiliary assemblies are arranged and are installed on the two sides of the installation seat respectively, a laser cutting knife and a positioning head are installed above the two auxiliary assemblies respectively and are used for cutting, a positioning assembly is used for sensing that a workpiece is output to a set position and then transmitting a signal to the PLC end, the PLC end controls the sliding block and the positioning assembly to move at the workpiece output speed, then the workpiece is accurately cut, the forming machine body is provided with a cutting station, cutting after shutdown is not needed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of roll forming technology, in particular to a PLC-based cold drawing numerical control roll forming machine. Background technique [0002] The principle of the cold drawing rolling forming machine is that the workpiece is not cut, and the two horizontal rollers rotate relative to each other, so that the workpiece is squeezed by the radial force at both ends, and an auxiliary pulling force is applied in the axial direction to make the inner crystal of the workpiece The granular structure changes, and the internal structure after forming undergoes a fundamental change, realizing roll forming. [0003] Existing roll forming machines only perform roll forming. For longer raw materials, they are cut after the rolling process is completed. Since the cutting station is carried out by using other equipment alone, it is necessary to carry out long-distance processing for longer raw materials at this time. Cutting and process...

Problems solved by technology

[0004] The purpose of the present invention is to provide a PLC-based cold-stretching numerical control roll forming machine, aiming to solve the problem that the roll forming machine in the prior art only performs roll forming, and cuts after the rolling process is completed. Long raw materials are cut and processed after long-distance transshipment, resulting in increased working hours and reduced work efficiency.
