Abstract
The invention discloses a novel wear-resisting point-attack pick. The novel wear-resisting point-attack pick mainly comprises a pick body and a hard alloy. The pick body is composed of a pick head and a pick handle, the hard alloy is welded to an alloy hole of the pick body and composed of a cone-shaped big head and a cylinder-shaped small handle, the small handle of the hard alloy is evenly provided with protruded ribs which are arranged longitudinally, the bottom of the small handle is provided with a concave counterbored hole, and the pick handle of the pick body is provided with a clamp spring through an annular concave clamp groove in a clamped mode; the periphery of the pick head is provided with a wear-resisting layer, and the wear-resisting layer is metal carbide compounded by chromium, vanadium and niobium metal powder and a nonmetallic boron and carbon compound material. The novel wear-resisting point-attack pick has the advantages that the welding quality is high, wear is resistant, the alloy structure is reasonable, the use amount is few, and the working is stable; the service life of the point-attack pick is effectively prolonged.
Description
Technical field
The present invention relates to coal mining boring tool field, specifically a kind of novel wear resistant pick-like bit.
Background technology
Pick-like bit is vulnerable part, coordinates with other cutter, completes the construction of coal mining, quarrying, hydroelectric project etc.Pick-like bit mainly comprises pick body and the soldering carbide alloy composition on pick body, in use, due to the wearing and tearing of alloy body, can not available protecting pick body, and cause the excessive wear of tooth head.Carbide alloy adopts plane soldering simultaneously, and there is the phenomenon that weld seam became uneven is even, soldering fastness is poor, easily causes alloy head to come off, affect the whole service life of pick body in using.
Summary of the invention
The present invention aims to provide a kind of practical novel wear resistant pick-like bit.
For realizing described object, the invention provides following technical scheme: a kind of novel wear resistant pick-like bit, mainly comprise pick body and carbide alloy, pick body is by tooth head, tooth handle forms, and carbide alloy is welded in the alloy hole of pick body, and carbide alloy is made up of conical major part and cylindrical stalklet, the stalklet of described carbide alloy is evenly provided with longitudinal raised ribs, and the bottom of stalklet is provided with the counterbore of indent; The tooth handle of pick body is installed with jump ring by annular indent draw-in groove; Tooth head periphery is provided with wearing layer, and described wearing layer is the composite metal carbides of chromium, vanadium, niobium metal powders and nonmetal boron, carbon compound material.
Described counterbore is designed to hemispherical.
Described raised ribs is set to two or more.
Described wearing layer is separately positioned on the corselet place of tooth head and the tooth head place of periphery, alloy hole.
Described jump ring has clearance aperture, and the corner of the jump ring at clearance aperture place is set to chamfering.
Compared with prior art, the invention has the beneficial effects as follows: tooth handle is installed on toothholder by jump ring, be convenient to the installation of pick, dismounting, the wearing layer available protecting tooth head set up, improve the anti-wear performance of pick body; On stalklet, the counterbore of indent, increases bonding area, improves firm welding degree, decreases the use amount of carbide alloy simultaneously; The raised ribs of setting up, is convenient to welding, ensure that the thickness of all even weld seam of welding is consistent simultaneously.Have welding quality high, wear-resistant, alloy structure is reasonable, use amount is few, and the effect of stable working effectively improves the application life of pick-like bit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view along A-A section in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, in the embodiment of the present invention, a kind of novel wear resistant pick-like bit, mainly comprise pick body and the carbide alloy 1 of soldering in pick body alloy hole, pick body is by tooth head 2, and tooth handle 3 forms, and carbide alloy 1 is made up of conical major part and cylindrical stalklet.The excircle of tooth handle 3 has annular indent draw-in groove, in draw-in groove, clamps jump ring 6.Described jump ring 6 has clearance aperture, and the corner of the jump ring 6 at clearance aperture place is designed to chamfering, is convenient to the dismounting of pick.Apply certain force vertically during installation, get final product pick setting.At the tooth head 2 place build-up wear-resistant material of the corselet place of tooth head 2 and periphery, alloy hole; form the wearing layer 7 of projection; described wearing layer 7 is the composite metal carbides of chromium, vanadium, niobium metal powders and nonmetal boron, carbon compound material, can available protecting pick body.The stalklet of carbide alloy 1 is evenly provided with longitudinal raised ribs 4, and ensure the even of soldered seam, raised ribs 4 is set to two or more.The counterbore 5 of indent is provided with bottom the stalklet of carbide alloy 1; This counterbore 5 is designed to hemispherical or near hemispherical, also can be designed to other shape.
To those skilled in the art, obviously the invention is not restricted to the details of described one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of described explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
