Problems solved by technology

[0002] At present, the welding tools used for processing holes, such as expanding tools and reamers, etc., because the carbide blade is welded to the high-speed material tool body with copper brazing filler metal, the diameter of the blade is fixed, and the tool is worn after it is put into use. , it is often impossible to continue grinding, resulting in scrapping after a period of use, which is quite wasteful, and the short service life of the tool will increase the processing cost of the product

Embodiment Construction

[0017] With reference to accompanying drawing, the method for this chisel repair tool, comprises the following steps:

[0018] (1) use the chisel tool 5 to moderately chisel the copper solder 1 between the cutter body 3 and the blade 2 of the wear cutter, so that a small amount of plastic deformation is produced between the copper solder 1 metal crystal and the amount of plastic deformation. Between 0.03-0.05mm, the blade 2 is slightly moved away from the center of the cutter body 3, the distance from the blade 4 to the center of the cutter 2 is increased, the overall diameter of the cutter is increased, and the diameter of the cutter reduced due to wear is compensated . This chisel tool 5 can adopt common chisel tool grinding to make, and the shape between chisel tool and cutter body 3 and blade 2 is adapted to get final product, also can adopt specially made chisel tool.

[0019] (2) Grinding the outer circle of the tool after chiseling, so that the blade 4 can be restored ...

Abstract

The invention discloses a method to mend cutting tool that includes the following steps: using carving tool to press copper solder between cutting tool and blade to make the copper solder crystal cause plastic distortion; thinning the outer circle of cutting tool to restore design work space size; thinning any angle of the blade to make the blade restore design work angle. The method prolongs useful life and decreases machining cost.

Description

technical field [0001] The invention relates to a method for repairing a tool, in particular to a method for chiseling a tool. Background technique [0002] At present, the welding tools used for processing holes, such as expanding tools and reamers, etc., because the carbide blade is welded to the high-speed material tool body with copper brazing filler metal, the diameter of the blade is fixed, and the tool is worn after it is put into use. , It is often impossible to continue grinding, resulting in scrapping after a period of use, which is quite wasteful, and the short service life of the tool will increase the processing cost of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for chiseling and repairing a tool, which can prolong the service life of the tool and reduce the processing cost with a low-cost repair process. [0004] In order to solve the problems of the technologies describe...
