Abstract
The invention relates to a field of digging machinery, especially to an abrasion-proof cutting pick used for cutting during digging and a process method thereof. The abrasion-proof cutting pick at least comprises a hard alloy cutter head, a main body, a cutting pick head, a cutting pick body and a clamping spring groove, and is characterized in that the clamping spring groove used for connecting with a mining machine is arranged at the position of the cutting pick body close to the bottom end; the upper end of the cutting pick body is fixedly connected with the cutting pick head; the cutting pick head is provided with the hard alloy cutter head in a fixing manner through the cutting head main body; and the outer surfaces of the hard alloy cutter head and the main body are provided with abrasion-proof layers. As the outer surfaces of the hard alloy cutter head and the main body part of the cutting pick are provided with the abrasion-proof layers in the fixing manner through a laser cladding technique, hardness and abrasion resistance of the cutting pick are increased greatly.
Description
Technical field
The present invention relates to the mining machinery field, wear-resisting type pick and process thereof that particularly cutting is used during a kind of digging.
Background technology
Pick is as the cutter of mining machinery cutting coal or rock, because of the difference of geological conditions also different to the instructions for use of pick, pick directly contacts with work plane, need very high rigidity and abrasion resistance, in the past pick work plane hardness and abrasion resistance are inadequate, often occur the tooth head rupture, wearing and tearing comparatively serious, directly affect production efficiency, for inferior we increased surperficial hardness and abrasion resistance.
Summary of the invention
The purpose of this invention is to provide a kind of wear-resisting type pick and process thereof, this pick has high rigidity and abrasion resistance.
The technical scheme that the present invention solves its technical problem employing is: a kind of wear-resisting type pick and process thereof, which comprises at least carbide bit, main body, tooth head, denticle, jump-ring slot, it is characterized in that: denticle closes on bottom position and is useful on the jump-ring slot that is connected with digger, the upper end of denticle is fixedly connected with the tooth head, the tooth head is fixed with carbide bit by its tooth head main body, and the outer surface of carbide bit and main body has wearing layer.
The height of described wearing layer is 5mm.
Described wearing layer is to be fixed on the outer surface of carbide bit and main body by laser melting coating.
The invention has the beneficial effects as follows: owing to being fixed with wearing layer by laser melting and coating technique at the carbide bit of pick and the external surface of main part, therefore increased greatly hardness and the abrasion resistance of pick.
Description of drawings
The present invention is further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is this wear-resisting type cutting tooth structure schematic diagram;
In figure: 1, carbide bit; 2, wearing layer; 3, main body; 4, tooth head; 5, denticle; 6, jump-ring slot.
The specific embodiment
Embodiment 1
As shown in this wear-resisting type cutting tooth structure schematic diagram of Fig. 1, which comprises at least carbide bit 1, main body 3, tooth head 4, denticle 5, jump-ring slot 6, denticle 5 closes on bottom position and is useful on the jump-ring slot 6 that is connected with digger, the upper end of denticle 5 is fixedly connected with tooth head 4, tooth head 4 is fixed with carbide bit 1 by its tooth head main body 3, the outer surface of carbide bit 1 and main body 3 has wearing layer 2, and the height of wearing layer 2 is 5mm.
Embodiment 2
Wearing layer 2 is by cubic boron 5%, tungsten carbide 3%, carborundum 15%, colophony powder 10%, silicate of soda 2%, turpentine oil 4% all the other wear-resisting powder that consist of for iron powder, all be weight percentage, draw through overtesting and also have good hardness when the wear-resisting powder that adopts this proportioning has high-wearing feature, wearing layer 2 is to be fixed on the outer surface of carbide bit 1 and main body 3 by laser melting coating, laser melting and coating technique has in each field generally to be used, and does not describe in detail herein.
Claims (3)
1. wear-resisting type pick, which comprises at least carbide bit, main body, tooth head, denticle, jump-ring slot, it is characterized in that: denticle closes on bottom position and is useful on the jump-ring slot that is connected with digger, the upper end of denticle is fixedly connected with the tooth head, the tooth head is fixed with carbide bit by its tooth head main body, and the outer surface of carbide bit and main body has wearing layer.
2. a kind of wear-resisting type pick according to claim 1, it is characterized in that: the height of described wearing layer is 5mm.
