A device for band saw welding and grinding

Abstract

The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a device for band saw welding and grinding. Comprising a workbench (9) supported by a plurality of columns (13); a slide rail (1) is provided on the workbench (9), a slide block (6) is provided on the slide rail (1), and a slide block ( 6) There is a mounting plate (5) on it, a groove (2) parallel to the slide rail (1) is arranged on the upper surface of the workbench (9), and an electromagnet (3) is embedded in the bottom of the groove (2). ); the inner end of the mounting plate (5) is provided with a mill (4), and the bottom of its grinding wheel is flush with the bottom of the groove (2); the end of the workbench (9) is installed by the support body (8) There is a first air cylinder (7), the end of the piston rod of the first air cylinder (7) is fixedly connected with the mounting plate (5); and a positioning device (11) for positioning the band saw to be welded is also included.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a device for band saw welding and grinding. Background technique [0002] In the field of machining, circular band saws are often used to cut metal bars. With the prolongation of the use time of the band saw blade, the cutting edge of the band saw blade gradually becomes blunt, or the saw teeth are missing due to external force, which is more likely to cause the band saw to break. At this point, the damaged band saw needs to be replaced. The disassembled band saw needs to be repaired, that is, the damaged section is removed, the length is made up with a good band saw section and welded to form a usable new band saw. When welding, it is required to butt two band saws that have finished cross-section grinding, and at the same time ensure that the tooth pitch of the welding part is equal to the original tooth pitch of the band saw. After the so...

AI Technical Summary

Problems solved by technology

In the prior art, the welding and grinding operations are generally carried out manually, which is not only time-consuming and laborious, but also difficult to guarantee the grinding effect

At the same time, due to the lack of reasonable technical means, the tooth pitch of the welded parts of the two band saws that have been welded is difficult to meet the requirements, which will affect the subsequent use of the band saw
