Abstract
A separable pick-shaped cutter comprises a cutting pick body and a cutting pick head, wherein the cutting pick body and the cutting pick head are detachable, the cutting pick head is inserted into the top of the cutting pick body and is in shaft and steel ball fit with the cutting pick body, and steel balls under the action of bolts and compression springs are evenly arranged around the top of the cutting pick body; anti-abrasion layers are arranged on the surface of the cutting pick body and the surface of the cutting pick head, and the anti-abrasion layers are made of metal carbides compounded from chrome, vanadium and niobium metal powder and nonmetal boron and carbon compounds. According to the separable pick-shaped cutter, the cutter can rotate in the stress direction of a conical spiral surface, the cutting pick head can rotate alone under the condition that generated cutting resistance is small, and eccentric wear of a carbide bit is effectively prevented; furthermore, due to the fact that the cutting pick body and the cutting pick head are two separated parts, the cutting pick head can be replaced, the reusing rate of the cutting pick body can be increased, and resources can be saved; due to the fact that the anti-abrasion layers are arranged on the surface of the cutting pick body and the surface of the cutting pick head to effectively protect the cutting pick body and the cutting pick head, the anti-abrasion performance of the cutting pick body and the cutting pick head is improved.
Description
Technical field
The present invention relates to coal mining boring tool field, specifically a kind of can the pick-like bit of split.
Background technology
Along with expanding economy, as the pick of vitals on coal-winning machine and development machine, its functional performance directly has influence on the operating efficiency of coal-winning machine and development machine.Due in the cutting course of cutting mechanism, the degree of depth of cutting of declined coal about reaches 3-4cm, and cutting pick head top is taper seat, at work, resistance because of phenomenon generations such as bending and tooth inner room fire plugs is often greater than the frictional force suffered by pick circumference, whole pick is caused normally not rotate, carbide bit is caused to wear and tear thus extremely uneven, and the eccentric wear of carbide bit causes cutting pick head top to reduce diameter fast, carbide bit loses protection and supports and come off and scrap, so, not only cause pick low for application life, and pick entirety is scrapped, cause unnecessary waste.
At present, in disclosed rotary cutting bit, mostly be the various fin that distributes at cutting pick head top, producing cutting resistance makes whole pick rotate, and between adjacent two fins, produce comparative resistance, make the resistance of generation less, the whole pick anglec of rotation is little, even can not rotate, carbide bit eccentric wear phenomenon does not well solve.
Summary of the invention
The present invention aim to provide a kind of practical can the pick-like bit of split.
For realizing described object, the invention provides following technical scheme: a kind of can the pick-like bit of split, comprise pick body, cutting pick head, the two is removable, described cutting pick head be inserted into pick body top and be axle with pick body, steel ball coordinates; Evenly be provided with the steel ball under bolt compresses spring action around the top of described pick body, two circles are arranged to by steel ball and the quantity of often enclosing is set to 5-8; Described cutting pick head and pick surface are provided with wearing layer, and wearing layer is the composite metal carbides of chromium, vanadium, niobium metal powders and nonmetal boron, carbon compound material.
The welded top of described cutting pick head is provided with carbide bit, and at it, carbide bit place is provided with cone-type spiral face.
The thickness of described wearing layer is 0.5-1mm.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can not only make pick rotate along cone-type spiral face Impact direction, and cutting pick head can be made to rotate separately when producing cutting resistance and being less, effectively prevent carbide bit generation eccentric wear phenomenon.In addition, because pick body and cutting pick head are two parts, can cutting pick head be changed, improve the repeat usage of pick body, reach the effect economized on resources.Pick body, cutting pick head surface are provided with wearing layer, and wearing layer can available protecting pick body, cutting pick head, improve the anti-wear performance of pick body, cutting pick head.

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. 1-4, in the embodiment of the present invention, a kind of can the pick-like bit of split, its objective is that reaching cutting pick head 2 can rotate, pick body 1 also can rotate and can reuse.The present invention forms primarily of pick body 1, cutting pick head 2, and two number of turns amounts that evenly arrange around the top of pick body 1 are 5-8 steel ball 7, and steel ball 7 is in impaction state under the effect of bolt 5 Compress Spring 6; The cutting pick head 2 that welded top is provided with carbide bit 3 is inserted into pick body 1 top, and the two adopts axle to coordinate with steel ball 7.
Because cutting pick head 2 is provided with cone-type spiral face 4 near carbide bit 3 place, in broken coal process, coal is by with different angle generation avalanches, coal fall makes cutting pick head 2 top tapered helicoid 4 produce larger cutting resistance, and the cutting resistance that therefore respective side produces due to employing transition cambered surface is less, this pick-like bit is rotated along cone-type spiral face 4 Impact direction, effectively prevents pick generation eccentric wear phenomenon.
Pick body 1 and cutting pick head 2 adopt axle, steel ball 7 coordinates, reduce and rotate Cutting Drag used, even if effectively ensure that pick-like bit cutting pick head 2 under less Cutting Drag can rotate separately, and steel ball 7 is set to two circles makes pick-like bit steadily rotate along setting angle axis, cutting pick head and pick body axis bias phenomenon after avoiding rotation.Pick body 1 and cutting pick head 2 are two parts, replaceable cutting pick head, improve the repeat usage of pick body, reach the effect economized on resources.
Described pick body 1, cutting pick head 2 surface are provided with wearing layer, and wearing layer can available protecting pick body 1, cutting pick head 2, improve the anti-wear performance of pick body 1, cutting pick head 2; Described wearing layer is the composite metal carbides of chromium, vanadium, niobium metal powders and nonmetal boron, carbon compound material, and thickness is 0.5-1mm.
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.
