Abstract
The utility model discloses a strenghthened type pick with first prong of pestering, the strenghthened type pick includes the base member and locates the dried mushroom head polycrystalline diamond composite tooth on the base member, dried mushroom head polycrystalline diamond composite tooth welds in the welding hole on the pick base member through brazing, be equipped with cyclic annular wearing layer on the pick base member. The utility model discloses a strenghthened type pick, impact resistance and wearability improve greatly to the life of pick has been prolonged, and have the advantage of high strength, high wearing feature, high impact resistance toughness.
Description
Technical field
This utility model belongs to tunnelling machine, coal-winning machine and shield machine field, is specifically related to a kind of novel Enhanced cutting pick.
Background technology
In the prior art, development machine, comprehensive milling machine and shield machine are widely used in various colliery and tunnel piercing；Cutterhead is development machine, combines milling machine and the critical piece of shield machine, and pick is fixed on cutterhead by toothholder, and pick generally uses hard alloy crown (referred to as hard alloy pick), mostly is the profile of circular cone, and is directly anchored on corresponding base.In practical work process, cutterhead by pick cutting rock, is main stressed member in the way of impact.
Wherein, when running into the higher rock stratum of hardness, by bigger shock loading and friction, hard alloy pick thereon abrasion is very fast, has had a strong impact on the work efficiency of road heading machinery and comprehensive mining machinery.
Its failure mode of the common pick of tradition mainly has two kinds:
One abrasion rapidly being as hard alloy crown, pick rust, it is difficult to cutting effective to rock formation, reach to a certain degree when the pick on whole cutterhead weares and teares, drivage efficiency will be remarkably decreased；
Two is owing to pick matrix is arranged on toothholder; pick matrix wears no resistance; pick matrix surrounding elder generation hard alloy pick point abrasion in work; when heavy wear; pick matrix loses the support protective effect to crown; so that crown is the most completely worn out, entirety is come off, cut tooth losing efficiency, need impact strength and the more preferable pick of wearability in therefore producing.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides the Enhanced cutting pick that a kind of impact resistance is strong, wearability is high.
The scheme that the above-mentioned technical problem of this utility model solution is taked is as follows:
A kind of Enhanced cutting pick with mushroom head crown, it is characterised in that described Enhanced cutting pick includes matrix and the dried mushroom head polycrystal diamond composite teeth being located on matrix；Described dried mushroom head polycrystal diamond composite teeth is by Welding welding hole on pick matrix；Described pick matrix is provided with annular wear layer.
Further, described dried mushroom head polycrystal diamond composite teeth includes tooth head and tooth body, and described tooth crown end is spheroidal crown；Described tooth body and tooth head junction are provided with tooth body platform, have arc transition portion between described tooth body platform and tooth body.
Further, the tooth head of described dried mushroom head polycrystal diamond composite teeth is coated with polycrystalline diamond layer；The diamond layer thickness of described tooth head is 0.2 ~ 3mm.
Further, a diameter of ￠ 13 ~ ￠ 35 of described tooth body platform, spherical radius R of described spheroidal crown is 0.5 ~ 8mm.
Further, the bottom of described matrix underpart is provided with the jump-ring slot fixed with pick base.
Further, the wearing layer thickness 0.2 ~ 3mm on described matrix top, the thickness of described wearing layer is gradually reduced to big end from matrix small end.
After this utility model takes such scheme so that impact resistance and wearability greatly improve, and there is high intensity, high-wearing feature, the advantage of high impact-resistant toughness.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in detail, so that above-mentioned advantage of the present utility model is definitely.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model pick matrix；
Fig. 3 is the structural representation of dried mushroom head polycrystalline diamond double tooth；
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
A kind of Enhanced cutting pick with mushroom head crown as Figure 1-3, it is characterised in that described Enhanced cutting pick includes matrix 3 and the dried mushroom head polycrystal diamond composite teeth being located on matrix 3；Described dried mushroom head polycrystal diamond composite teeth is by Welding welding hole 2 on pick matrix 3；Described pick matrix is provided with annular wear layer 1.Facts have proved that annular wear can bear more large impact power, also enhance wearability.The impact resistance and the wearability that make pick matrix are greatly improved, and increase the service life.The wearing layer thickness 0.2 ~ 3mm on described matrix top, the thickness of described wearing layer is gradually reduced to big end from matrix small end；The bottom of described matrix underpart is provided with the jump-ring slot 4 fixed with pick base.
By Fig. 3 it will be seen that described dried mushroom head polycrystal diamond composite teeth includes: tooth head 6 and tooth body 9, described tooth head 6 top is spheroidal crown 5；Described tooth body 9 is provided with tooth body platform 7 with tooth head 6 junction, has the excessive portion of circular arc 8 between described tooth body platform 7 and tooth body 9；Described tooth body 9 is fixing with pick matrix to be connected, and the diameter of tooth body platform 7 is divided into ￠ 13 ~ ￠ 35, spherical radius R of spheroidal crown 5 to be 0.5 ~ 8mm, and the diamond layer thickness of spheroidal crown 5 and tooth head 6 is 0.2 ~ 3mm.
The tooth head of described dried mushroom head polycrystal diamond composite teeth is coated with polycrystalline diamond layer；The diamond layer thickness of described tooth head is 0.2 ~ 3mm.
This utility model uses spheroidal crown and tooth head, substantially increase impact resistance and the wearability of diamond composite teeth, and there are high intensity, high-wearing feature, these good characteristics of high impact-resistant toughness so that it is can apply coal seam, rock stratum digging in, replace hard alloy.
Arc transition portion 8 set by the welding hole 2 of described pick matrix and tooth body coordinates, good support is provided for dried mushroom head polycrystal diamond composite teeth, the stress of composite teeth and welding hole can be disperseed, and composite teeth is had cushioning effect, substantially increase the impact resistance of composite teeth.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.It will be understood by those skilled in the art that specific descriptions above are intended merely to explain the purpose of this utility model, be not intended to limit this utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
