Abstract
The invention discloses a wear-resistant and anti-falling pickaxe-shaped cutting pick, which comprises a cutting pick body and a hard alloy tool bit, wherein the cutting pick body consists of a cutting pick head and a cutting pick handle; the hard alloy tool bit is embedded into the front end of the cutting pick head; the cutting pick head is a conical body; spiral grooves are uniformly distributed in the cutting pick head along the conical body from top to bottom; spiral ribs made of a hard alloy wear-resistant material are arranged in the spiral grooves, and are in metallurgical combination with the cutting pick head; a circular hole is formed at the top end of the cutting pick body; and the hard alloy tool bit is arranged in the circular hole, and is welded together with the circular hole. Due to the adoption of the wear-resistant and anti-falling pickaxe-shaped cutting pick, the cutting pick head is effectively prevented from falling off, the overall strength and the wear resistance of the cutting pick are greatly enhanced, and an economic benefit is remarkably achieved.
Description
Technical field
The present invention relates to engineering goods, the wear-proof head separation prevention pickaxe type cutting pick of the cutting part of particularly a kind of colliery extractive equipment.
Background technology
Used pick-shaped cutter on the extractive equipment of present colliery; Major part is to be processed through technologies such as machine, soldering and heat treatments by alloy steel denticle and carbide bit, and its life-span length is determined by quality, soldering processes and the Technology for Heating Processing of carbide bit.Pick normal abandonment and the principal element of scrapping too early are that carbide bit comes off.The reason that causes carbide bit to come off mainly contains carbide bit and the joint portion of pick body, and worn out bad to cause carbide bit to be connected with the pick body loosening with brazing quality.In order to address this problem, people are studying better pick-shaped cutter always.The carbide bit shearer pick-shaped cutter of tapering " band " that is designed like Heilungkiang institute is that denticle is bored from bottom to top and forms up-small and down-big taper hole at the denticle top; Supporting with it tapered hard is closed the tooth golden head hold out against from the bottom, denticle tooth head two conical surfaces are closely linked with the push rod screw.This pick descends because of denticle hollow causes the bulk strength of pick.What also have prevents that with embedding method the tooth head from coming off." the coal-winning machine castingin pick " that designed like Jiamusi institute is earlier the hard-metal insert head to be managed fixing cast molding again, and same the influence because of the denticle strength deficiency of casting of this pick applied.Also have person skilled on brazing material and technology and whole heat treatment process, to seek better solution, but effect is all not obvious.In sum, also do not have a kind of carbide bit that not only effectively prevented to come off but also strengthened pick bulk strength and abrasion resistance pick-like bit at present, therefore, how effectively to solve this technical barrier, by being paid close attention in the industry.
Summary of the invention
To above-mentioned situation, for overcoming the prior art defective, the object of the invention provides a kind of wear-proof head separation prevention pickaxe type cutting pick, can effectively solve to prevent that the tooth head from coming off and can improve the problem of pick bulk strength and abrasion resistance.
The present invention realizes through following technical scheme:
Wear-proof head separation prevention pickaxe type cutting pick; Comprise that pick body, carbide bit, described pick body are made up of cutting pick head and pick handle, described carbide bit is embedded in the cutting pick head front end, and described cutting pick head is a bullet; Described cutting pick head is evenly equipped with helical groove from top to bottom along bullet; Carbide alloy high-abrasive material spiral ridge is housed in the described helical groove, and described spiral ridge and cutting pick head are metallurgical binding, and described pick body top is provided with circular hole; Described carbide bit is contained in the circular hole, welds together.
Said circular-hole internal-wall is shape of threads, and carbide bit is the face of cylinder, and the screw thread that matches with the circular hole internal thread is arranged on its face, and the carbide bit spinning by at the bottom of the full hole of the scolder of fusing and thread pitch, is solidified as a whole its condensation in circular hole.
This reality has new structure simple, and product quality is high, prevents that effectively the tooth head from coming off, and has strengthened pick bulk strength and abrasion resistance greatly, and remarkable economic efficiency is arranged.In order to guarantee result of use, 2-6 the helicla flute of said groove 4 for being uniformly distributed with, wide 5-6mm, dark 2-3mm; Said spiral ridge 5 is relative with groove quantity.
Description of drawings
Fig. 1 is the structural front view of the embodiment of the invention,
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
Elaborate below in conjunction with the accompanying drawing specific embodiments of the invention.
Referring to accompanying drawing 1, Fig. 2, a kind of wear-proof head separation prevention pickaxe type cutting pick comprises that pick body, carbide bit 2, described pick body are made up of cutting pick head 1 and pick handle 3; Described cutting pick head 1 is a bullet, and described cutting pick head 1 is evenly equipped with helical groove 4 from top to bottom along bullet, and carbide alloy high-abrasive material spiral ridge 5 is housed in the described helical groove 4; Described spiral ridge 5 is a metallurgical binding with cutting pick head 1; Described pick body top is provided with circular hole 6, and described circular hole 6 inwalls are shape of threads, and carbide bit 2 is the face of cylinder; The screw thread that matches with circular hole 6 internal threads is arranged on its face; Carbide bit 2 spinnings by at the bottom of the full hole of the scolder of fusing and thread pitch, weld together its condensation are solidified as a whole in circular hole 6.
Can find out by above-mentioned situation; The present invention has increased bonding area owing to carbide bit 2 has adopted to be threaded with the pick body; This moment, carbide bit 2 was weld force and the dual stack of fastening force with the adhesion of pick body, therefore, had increased the bonding strength of the two greatly; Reached and prevented carbide bit 2 purpose that comes off; The spiral ridge 5 that is uniformly distributed with along the conical surface has played wear-resisting and double action permanent tooth, and this is that other wear-proof head separation prevention pickaxe type cutting picks institutes are inaccessible at present, has remarkable economic efficiency.
Embodiment is just for the ease of understanding technical scheme of the present invention; Do not constitute restriction to protection domain of the present invention; Every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technical scheme of the present invention all still belongs within the protection domain of the present invention.
