Problems solved by technology

[0003] When the existing steel is cold-processed, most of the steel is processed into a specified plate-shaped structure by stamping and cutting. When the steel needs to be cold-pressed into a cylindrical structure, the steel needs to be rolled. Most of the two ends of the pressure roller on the machine are independently adjusted by the bearing seat and the adjusting screw, so when adjusting the pressure roller, it is easy to cause the force of the two ends of the pressure roller to squeeze the steel to be inconsistent, resulting in the pressure on the two edges of the steel. difference, affecting the regularity and wall thickness of the roll

Embodiment 1

[0052] A kind of steel coiling process, its step comprises:

[0053] S1 blank processing, cutting the steel material into a blank of required size, specifically, the steps of step S1 blank processing include:

[0054] S11 Scribing, use a talc pen to draw a rectangular marking line on the steel surface according to the marking line of the specified specification;

[0055] S12 cutting, cutting the steel along the marking line to obtain the blank plate, ensuring good parallelism between the blank plate and the edge of the blank plate;

[0056] S13 splicing, welding a plurality of slabs to form a plate-shaped blank, specifically, welding the slabs by electric welding, and then welding along the edges of the slabs to form a welded edge;

[0057] S2 grinding, grinding the plane of the cut blank, and grinding along the edge of the blank to remove burrs, specifically, the specific steps of step S2 grinding include:

[0058] S21 pre-pressing, cold pressing the welding part of the sla...

Abstract

The invention discloses a steel rolling process and a rolling machine, relates to steel processing, and aims to solve the problems that when adjustment is carried out on compression rollers, the acting force of the two ends of the compression rollers to steel is easily inconsistent, the pressure borne by the two edges of the steel is different, and the regularity and the wall thickness of rolling are affected. According to the key points of the technical scheme, the rolling machine comprises a machine frame, supporting frames are fixedly connected to the machine frame, a plurality of transmission rollers are rotationally connected to a position between the supporting frames, the compression rollers rotationally connected with the supporting frames are slidably connected to the supporting frames, adjusting assemblies connected with the compression rollers to drive the compression rollers to move vertically are arranged at the top ends of the supporting frames, and a balancing rod is arranged between the adjacent adjusting assemblies in a hinged mode. According to the steel rolling process and the rolling machine, the balance rod is arranged between the two adjusting assemblies in a hinged mode, the two adjusting assemblies independently adjust the ends of the compression rollers, people can judge the levelness of the compression rollers by detecting the levelness of the balance rod, then people can conveniently know the extrusion condition of the compression rollers on the steel and the transmission rollers, and the consistency of rolling of the steel is improved.

Description

technical field [0001] The invention relates to steel processing, more specifically, it relates to a steel rolling process and a rolling machine. Background technique [0002] Steel is a material of a certain shape, size and performance made of steel ingots, billets or steel through pressure processing. Most steel processing is through pressure processing, which causes plastic deformation of the processed steel (billet, ingot, etc.). According to the different processing temperature of steel, it can be divided into cold processing and hot processing. [0003] When the existing steel is cold-processed, most of the steel is processed into a specified plate-shaped structure by stamping and cutting. When the steel needs to be cold-pressed into a cylindrical structure, the steel needs to be rolled. Most of the two ends of the pressure roller on the machine are independently adjusted by the bearing seat and the adjusting screw, so when adjusting the pressure roller, it is easy t...
