Method for processing wear-proof head separation prevention pickaxe type cutting pick

Abstract

The invention relates to a method for processing a wear-proof head separation prevention pickaxe type cutting pick, which can effectively solve the problems of gear head separation prevention and improvement of cutting pick whole strength and wear resistance. The method adopts the technical proposal that gear body is wholly forged into a gear body the upper part of which is a conical body; grooves which are evenly distributed are arranged along the conical surface of the gear body;; after modifying and cleaning treatment, alloy ceramic powder is clad into strip strengthening ribs along the grooves evenly distributed on the gear body; a hole is drilled on the top end of the gear body, and thread is machined on the inner wall of the hole; solder is put into the whole; the gear head of the cylindrical surface with thread is screwed inwards for one to two circles to be heated to 930 to 950 DEG C; and after the solder is completely melted, the gear head is completely screwed into the gear body. The method has the advantages of simpleness, easy operation and high product quality, can effectively prevent gear head separation, greatly reinforces the whole strength and wear resistance of the cutting pick, and has significant economical benefit.

Description

1. Technical field [0001] The invention relates to mechanical processing, in particular to a processing method of a wear-resistant and anti-drop-off pick pick for cutting parts of coal mining equipment, that is, a pick-shaped pick manufacturing technology for wear resistance and preventing the gold tip of hard alloy teeth from falling off. 2. Background technology [0002] At present, most of the pick picks used in coal mining equipment are made of alloy steel tooth body and hard alloy tooth head through machining, brazing and heat treatment. , Brazing process and heat treatment process. The main factor for the normal scrapping and premature scrapping of picks is the shedding of the carbide tooth head. The main reasons for the shedding of the tooth head are the wear of the joint between the tooth body and the tooth head and the loose connection between the tooth body and the tooth head due to poor brazing quality. In order to solve this problem, the technicians of various ...

AI Technical Summary

Problems solved by technology

For example, the "coal shearer insert casting pick" designed by a certain college in Jiamusi is to try to fix the carbide tooth head and then cast it again. This process also affects the popularization and application because of the insufficient strength of the cast tooth body.

There are also relevant technical personnel looking for better solutions on brazing materials and processes as well as the overall heat treatment process, but the effect is not obvious

[0003] To sum up, there is currently no manufacturing method that can effectively prevent the tooth head from falling off and enhance the overall strength and wear resistance of the pick. Therefore, how to effectively solve this technical problem has attracted the attention of the industry.
