Description
Technical field
The utility model relates to a kind of mining pick, specifically a kind of wear-resisting conical pick gathering for engineering machinery, ore extraction and colliery.
Background technology
Coal is the basic energy resource of China, in disposable energy resource structure in absolute main positions.In recent years, be subject to the promotion of national economy fast development, coal in China output and consumption figure present the impetus of rapid growth, and along with the raising of coal mining machinery degree, the cutting power of coal-winning machine, development machine continues to increase, and supporting mining pick consumption increases day by day with it.For this reason, the problem that a kind of manufacturing process is simple, integrated cost is low in the urgent need to developing, the pick of long service life solves Vehicles Collected from Market pick high flow rate.
Pick is as the cutter of direct cut coal seam or broken rock, and working condition is severe, belongs to easily worn part.Statistics shows, the irregular wear inefficacy great majority of conical pick show as denticle front end and burst apart and wear and tear, and alloy cutter head also supports and comes off because losing too early protection; And the normal wear of conical pick was lost efficacy, also, how because of the front end later stage excessive wear of pick denticle, make carbide bit too outstanding, weld seam area reduces, thereby causes weld strength inadequate, causes the alloy cutter head of pick front end to come off.For avoiding coming off of pick front end alloy cutter head, improve pick application life, except improving brazing quality and weld strength, the more important thing is the abrasion resistance that improves pick body front end.
For this reason, Chinese scholars has been carried out a large amount of research to pick, from pick this body structure, has proposed numerous corrective measures, is exactly below several conventional measures:
(1) at the common wearing layer of pick denticle front-end-cone surface build-up welding or plasma panel wearing layer;
(2) at pick denticle front-end-cone face brazing alloy wear ring;
(3) at many strip wearable hard alloys of pick denticle front-end-cone face soldering.
Several corrective measures are in anti-wear performance and the application life of having improved in varying degrees pick above, but all do not reach desirable effect, still have that cost is high, the problem of production technology relative complex, and pick body front end position easy to wear exposes, alloy cutter head easily comes off, and cutting-gear life is still too low.
Utility model content

The technical scheme in the invention for solving the technical problem is: the wear-resisting conical pick of a kind of umbrella crown shape, comprise denticle and carbide bit, it is characterized in that, in the bottom of described carbide bit, be provided with the interior soldering hole of matching with described denticle front end, brazing between described denticle and carbide bit, and make described carbide bit bottom cover denticle front end position easy to wear.
Further, described carbide bit integral body is coniform, and described carbide bit male cone (strobilus masculinus) is divided into circular arc conical surface part and linear conical surface part to bottom from top, and seamlessly transits at the position that is bonded to each other.
Further, described denticle front end is a cone, and described interior soldering hole is coniform for what match with denticle front end.
Further, in the periphery of the circular arc conical surface part of described carbide bit, be evenly equipped with double-wedge section more than five to 12.
Further, in the periphery of the linear conical surface part of described carbide bit, be evenly equipped with three to 12 reinforcing ribs.
Further, described reinforcing rib and carbide bit are integrated.
Further, the number of described reinforcing rib and many double-wedge sections is six.
Further, described carbide bit is tungsten-cobalt hard alloy cutter head.
The beneficial effects of the utility model are: this conical pick can be given full play to the speciality of tungsten-cobalt hard alloy tool tip material, the key position that its high abrasion, impact resistance are badly in need of high-wearing feature at cutter is obtained a wide range of applications, and protection denticle front end is not frayed; When conical pick cut coal seam or broken rock, can not cause coming off of carbide bit because of the direct impact of getting thing with shovel, and can effectively prevent eccentric wear; In addition, the utility model also possesses the feature that manufacturing process is simple, integrated cost is low, is easy to be extended and applied.
