Abstract
The invention discloses a high-performance anti-falling cutting pick with a composite assembled structure. The cutting pick comprises a cutting pick shank, a cutting pick head, and a protective fixing sleeve. One end of the cutting pick shank is a fixing end. The other end of the cutting pick shank and the cutting pick head form a taper connection through self-locking. The cutting pick head has an inner taper hole, and the cutting pick shank has an outer taper shank. The protective fixing sleeve and the cutting pick head also form a taper connection through self-locking. The cutting pick head has an outer taper shank, and the protective fixing sleeve has an inner taper hole. The protective fixing sleeve and the cutting pick shank are threadedly connected. With the cutting pick provided by the invention, cutting pick head anti-falling capacity and cutting pick service life can be improved, construction efficiency can be effectively improved, and construction cost can be reduced.
Description
Technical field
The present invention relates to the pick that a kind of coal mining and engineering construction are used, relate in particular to a kind of anti-pick that comes off of combination assembly structure that has.
Background technology
In recent years, because the very big raising of engineering machinery host technology level and performance, as mining and the pick of the important construction tool of engineering machinery such as tunnelling has become the key factor that affects construction speed, efficient, quality, cost.Present pick is welded construction, and pick is comprised of pick body and cutting pick head two parts, and carbide alloy cutting pick head or polycrystalline diamond composite cutter bit head are welded on an end of pick body.There are two problems in the welded construction pick, and a problem is: from present manufacturing process, for improving abrasion resistance and the mechanical performance of pick body, need the pick body is heat-treated.The heat treatment of the soldering of cutting pick head and pick body produces the impact of contradiction on the pick performance like this.If at first the pick body is heat-treated, again with the cutting pick head soldering on cutter hub, then the heat that produces of cutting pick head soldering is influential to the pick body performance of carrying out Overheating Treatment; If first with the cutting pick head soldering on cutter hub, again the pick body is heat-treated, then the high temperature during heat treatment has a significant impact the performance of cutting pick head (carbide alloy or diamond tooth head), makes its performance degradation, abrasion resistance descends.Another major issue is: because the pick body is made by materials such as alloy steels, although carried out heat treatment, but the pick body wants fast many than the wearing and tearing of cutting pick head in work progress, causing cutting pick head to come off too early scraps, because pick is changed frequent, construction speed is slow, and efficient is low, of poor quality, integrated cost improves.For improving the abrasion resistance of pick body, except heat treatment, some other methods have also been proposed at present, as: at pick surface built-up welding one deck wear resistance electrode, at pick surface electroplated diamond, increase abrasion resistance at a plurality of carbide alloy gauge teeths of the external side of pick configuration etc., reach the gauge purpose.But still can't avoid cutting pick head soldering and pick body heat and process contradictory problems to the pick performance impact.
Soldering and pick body heat for cutting pick head are processed the impact that the pick performance is produced contradiction, and pick body Fast Wearing causes cutting pick head to come off too early to scrap this two large problems, invented to have the anti-high-performance pick that comes off of combination assembly structure that the self-locking tapering connects.
Summary of the invention
The objective of the invention is the cutting pick head soldering and the contradiction of pick body heat processing to the pick performance impact that exist for present welded construction pick, and pick body wearing and tearing the technical problem such as cause cutting pick head to come off too early scrapping, and a kind of anti-pick that comes off of assembling that the self-locking tapering links that has between cutting pick head and pick body is provided.Thereby improve the whole service life of pick, the abrasion resistance of carbide alloy cutting pick head or diamond cutting pick head is not fully exerted, reduce the pick replacement frequency, improve the efficiency of construction of coal mining and engineering machinery, reducing construction cost.
The technical scheme that adopts is
A kind of have an anti-pick that comes off of combination assembly structure
,Comprise cutting pick handle, cutting pick head and protection fixed cover, an end of cutting pick handle is bare terminal end, and the other end of cutting pick handle adopts the self-locking tapering to be connected with cutting pick head, and cutting pick head is internal taper hole, and cutting pick handle is outer taper shank; The protection fixed cover also adopts the self-locking tapering to be connected with cutting pick head, and cutting pick head is outer taper shank, and the protection fixed cover is internal taper hole; Between protection fixed cover and cutting pick handle for being threaded.
Above-mentioned cutting pick head material is carbide alloy or diamond.
The protection fixed cover is threaded connection on cutting pick handle during assembling, is connected the axial force that produces with the tapering of cutting pick head by the protection fixed cover simultaneously cutting pick head is pressed on cutting pick handle band tapering one end.By the self-locking performance of tapering between cutting pick head and cutting pick handle, protection fixed cover and cutting pick head, guarantee that cutting pick head reliably is connected with cutting pick handle, guarantee simultaneously to protect the reliability that is threaded between fixed cover and cutting pick handle.Because the assembly structure for being threaded between protection fixed cover and cutting pick handle, therefore protect the heat treatment of fixed cover and cutting pick handle or surface abrasion resistance and process and independently carry out, can not have influence on the performance of cutting pick head (carbide alloy cutting pick head or diamond cutting pick head).And, because cutting pick head and cutting pick handle adopt the self-locking tapering to be connected, even producing local excessive, the protection fixed cover weares and teares, can not cause coming off of cutting pick head yet, thus the anti-exfoliation ability of raising cutting pick head and pick application life.
Advantage of the present invention is:
1, pick of the present invention adopts fabricated construction, and heat treatment or the surface abrasion resistance processing of protection fixed cover and cutting pick handle are independently carried out, and can not have influence on the performance of carbide alloy cutting pick head or diamond cutting pick head.Thereby guaranteed that cutting pick head has had the high life-span.
2, heat treatment or the surface abrasion resistance processing of protection fixed cover and tooth handle are independently carried out, can not interact, the protection fixed cover can adopt different materials and processing method according to requirements with the tooth handle, make separately performance reach optimum aspect the instructions for use satisfying, thereby guaranteed that pick totally has optimum performance.
3, the present invention is worn and torn even the protection fixed cover produces local excessive because cutting pick head and cutting pick handle adopt the self-locking tapering to be connected, also can not cause coming off of cutting pick head, thus the anti-exfoliation ability of raising cutting pick head and pick application life.
4, the present invention is owing to being the self-locking performance tapering between cutting pick head and cutting pick handle, protection fixed cover and cutting pick head and being connected, and assurance cutting pick head, cutting pick handle and the connection of protecting between fixed cover are reliable, can not become flexible.
5, pick of the present invention, the performance of its carbide alloy cutting pick head or diamond cutting pick head is not affected by the pick manufacturing process and deteriorated, and anti-deciduous improves greatly, greatly reduces so that change the frequency of pick in the use procedure, thereby significantly improve efficiency of construction, and make the construction cost decrease.
