Abstract

The invention discloses a machining device and method for a steel channel grooving and bending combined assembly and belongs to the technical field of shearing and bending machining. The machining device comprises a rectangular groove cutting machining mold, a triangular groove cutting machining mold and a bending machining mold, wherein the rectangular groove cutting machining mold comprises a first movable cutter and a first fixed cutter; the first movable cutter is fixedly connected with a first movable cutter base, and the shearing edge face of the first movable cutter is a V-shaped face with the middle portion sunken downwards; the first fixed cutter is installed on a first fixed cutter base and forms a "rightward-right-angle-u-shaped" structure; the triangular groove cutting machining mold comprises a second fixed cutter and a second movable cutter; the second movable cutter is fixedly connected with a second movable cutter base; the shearing edge face of the second movable cutter is a plane inclined to the other side from the position of a sharp corner of the plane; and the second fixed cutter is installed on a second fixed cutter base and forms an "L-shaped" structure. By adopting the machining device to perform grooving and bending machining on steel channels, the machining efficiency and the machining quality can be remarkably improved, and the precision and the quality of the combined assembly are made to meet the using requirements.

Description

technical field [0001] The invention belongs to the technical field of shearing and bending, and more specifically relates to a processing device and method for a channel steel slotted and bent assembly. Background technique [0002] Channel steel is a long strip of steel with a groove-shaped cross-section. Channel steel is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Mechanical equipment and vehicle manufacturing, etc. Channel steel has a wide range of uses, and in some special occasions in actual production, it is necessary to process such as Figure 1a The groove shown, then bend the channel steel along the center line of the groove, and finally weld the gap between the grooves after bending to get the following Figure 1b Assemblies shown. [0003] Due to the complex structure of the channel steel, in the prior art, gas cutting is usually used to cut each side of the groove on the channel steel in Fig. T...
