Rolled steel bar drawing mechanism

Abstract

The invention provides a rolled steel bar drawing mechanism which belongs to the technical field of equipment for metal heat treatment, and solves the problems of high consumption of compressed air, and the like in the prior art. The rolled steel bar drawing mechanism comprises a steel rectangular bearing bottom table, wherein a steel annular track for enabling a steel rolling assembly on a steelrotary table to roll is arranged on the rectangular bearing bottom table; a steel center positioning pipe for sleeving a rolled steel bar bearing rack is arranged at the center of the rotary table; and one side of the rotary table is provided with a steel drawing structure which is fixedly arranged on the rectangular bearing bottom table to conveniently draw rolled steel bars arranged on the rotary table. The rolled steel bar drawing mechanism disclosed by the invention has the advantages that due to the arrangement of the steel annular track, the rotary table, the rolling assembly and the drawing structure, the rolled steel bars on the rotary table are conveniently rotated and drawn; due to the arrangement of the center positioning pipe, the rolled steel bar bearing rack is rapidly positioned and prevented from slipping to the rotary table in the rotating process, and the operating safety is improved.

Description

technical field [0001] The invention belongs to the technical field of equipment for metal heat treatment, and in particular relates to a pulling mechanism for rolled steel bars. Background technique [0002] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the surface of the workpiece. , to give or improve the performance of the workpiece. It is characterized by improving the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make metal workpieces have the required mechanical properties, physical properties and chemical properties, in addition to reasonable selection of materials and various forming processes, heat treatment processes are often essential. Steel...

AI Technical Summary

Problems solved by technology

Steel is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. Therefore, steel needs to be heat treated before it is used. The bearing capacity of metal after heat treatment The steel bearing frame needs to pull out the rolled steel bars. Since the bearing frame is fixed and cannot be rotated, there are defects such as laborious and inconvenient pulling.
