Steel round bar heading-off mechanism for plasma cutting machine

Abstract

The invention relates to a steel round bar heading-off mechanism for a plasma cutting machine and belongs to the technical field of metal cutting machinery. The plasma cutting machine comprises a rack formed by frist and second beam bodies, a plasma cutting mechanism, a steel round rod driving and transporting mechanism, a lifting frame and a group of steel round bar turnover mechanisms; the steel round bar heading-off mechanism is arranged at the end part of the other end of the rack; the steel round bar heading-off mechanism comprises a base, a bracket, an oil cylinder seat, an oil cylinder and a heading block; the base is arranged on the floor; the bracket is fixed on the base; carrier rollers are respectively arranged on the surface of the side of the bracket, which is toward the oil cylinder seat, and at both sides of the surface; the oil cylinder seat is fixed at the tops of one group of uprights; the bottoms of the one group of uprights are fixed together with the edge positon of the bracket; the oil cylinder is fixed at the center position of the oil cylinder seat; the heading block is connected to the tail end of an oil cylinder column; and an inverted V-shaped cavity is formed at the side of the heading block, which is toward the bracket. The steel round bar heading-off mechanism has the advantages of avoiding the material loss in the cutting process of a steel round bar, improving the heading-off efficiency, reducing the noise and saving electrode materials.

Description

technical field [0001] The invention belongs to the technical field of metal cutting machines, and in particular relates to a steel round bar upsetting mechanism for a plasma cutting machine. Background technique [0002] As known in the industry, the steel round bar mentioned above refers to the steel round bar used for processing steel pipes. The production of steel pipes generally needs to go through the following steps: steel round bar cutting, heating and piercing, annealing, cold rolling, cold drawing and heat treatment of finished products . Wherein, the steel round bar cutting step is to cut the steel round bar with a length of 6m or more to the required length, for example, cutting a steel round bar with a length of 6m to 1m, and cutting a steel round bar with a length of 9m to 1m or 1.5m, etc. [0003] In the prior art, the sawing method is generally used to cut the lengthy steel round bar to the required length. The shortcoming of the sawing method is: first, th...

Problems solved by technology

[0004] Undoubtedly, if the surface of the steel round bar is processed by the plasma cutting machine to form a ring-through surface gap, and then the upsetting mechanism is upset at the gap, then the aforementioned defects can be eliminated. However, in the disclosed Chinese and foreign There is no corresponding technical revelation in the patent and non-patent literature. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background
