Abstract
The utility model discloses rectangular strip hard rock conical cutting teeth, which are formed by a conical cutting teeth body, a tungsten-cobalt columnar central alloy and tungsten-cobalt alloy rectangular wearing strips. The utility model is characterized in that the tungsten-cobalt alloy rectangular wearing strips are distributed in rib radial pattern, the tungsten-cobalt columnar central alloy is arranged in cone-shape, rectangular grooves are fabricated and evenly distributed in the conical direction at the conical end of cutting teeth body on the basis of the original conical cutting teeth, the tungsten-cobalt alloy rectangular wearing strips are evenly brazed in the grooves and the number of the tungsten-cobalt alloy rectangular wearing strips equals to the number of the grooves; an annular conical wearing body is formed, the columnar central alloy takes the main cutting action when hard rocks are cut and the tungsten-cobalt alloy rectangular wearing strips protect the cuttingteeth so as to protect the cutting teeth body against wear and to prevent the central alloy from falling off; and moreover, after the wearing strips are brazed at the conical part of the cutting teeth, the rotation of the conical cutting teeth in operation is facilitated, the eccentric wear to the conical cutting teeth is effectively avoided and the service life of the conical cutting teeth is greatly prolonged. The rectangular strip hard rock conical cutting teeth can be widely used on the ore mining machinery, the coal mining machinery and the engineering machinery.
Description
Technical field
The utility model relates to a kind of conical pick, and more particularly, the utility model relates to a kind of rectangular strip hard rock conical pick.
Background technology
At present; the common conical pick of selling on the market is of a great variety; but exist many problems; at first; when common conical pick is worked on soft rock mass; can also use, in case run into hard rock mass, common conical pick is known from experience the wearing and tearing of quickening; can not play effective protective effect to the center alloy; when pick may wear to a certain degree, the center alloy will come off, and caused shorten the application life of conical pick; and cause the phenomenon of scrapping in advance; secondly, the use of common conical pick is restricted, is unfavorable for promoting and using.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, when solving common conical pick and on hard rock mass, working, the accelerated wear test of pick body, the center alloy comes off, and cause a difficult problem of scrapping in advance, provide a kind of wear-resistant, high rigidity, the rectangular strip hard rock conical pick of long service life.
The utility model is realized by following technical proposal:
The utility model is made up of conical pick body, tungsten cobalt column center alloy, tungsten-cobalt alloy rectangle wear rib, it is characterized in that tungsten-cobalt alloy rectangle wear rib is the radial distribution of umbrella frame, and tungsten cobalt column center alloy is tapered setting.
The utility model is the hard rock conical pick, its on the basis of original conical pick, by pick body tapered end, along awl to making equally distributed rectangular channel, soldering tungsten-cobalt alloy rectangle wear rib in groove, and evenly distributing, quantity equates; Tungsten-cobalt alloy rectangle wear rib end, contact and interconnect with tungsten cobalt column center alloy, it is radial to be umbrella frame after the soldering, makeup ring cone wear body, when it is worked at hard rock, tungsten cobalt column center alloy, the tapered end of its periphery pick body, to making equally distributed rectangular channel, and the tungsten-cobalt alloy rectangle wear rib of soldering respective numbers becomes one the two along awl, play main shear action by column center alloy, the tungsten-cobalt alloy wear rib plays the protection pick, and the pick body is not worn, and the center alloy of avoiding comes off; In addition, the soldering of pick conical section is wear-resisting
After, conical pick is rotated at work more favourable, prevented the eccentric wear of conical pick effectively, prolonged the application life of conical pick greatly.
The utility model is compared with prior art has following advantage:
1. have good comprehensive mechanical performances such as high rigidity, high tenacity, high-wearing feature;
2. manufacturing process is simple, and integrated cost is low;
3. long service life is the regeneration product of common pick;
4. be convenient to promote and use.
Description of drawings
Fig. 1 is a front view of the present utility model
Fig. 2 is a vertical view of the present utility model
The specific embodiment
1 pair of the utility model is described in detail in conjunction with the accompanying drawings:
The utility model is a kind of hard rock conical pick, is primarily aimed at the hard rock digging and brings into play its advantage function, and it is an external body of the present utility model by conical pick body 1; Tungsten cobalt column center alloy 2 is core of the present utility model positions, plays main shear action; Around the pick forecone, to several tungsten-cobalt alloy rectangle wear ribs 3 that distribute, the effect that it can protect the pick body is not worn the pick body along awl, and the center alloy of avoiding comes off; During work, behind the conical pick body 1 conical section soldering wear rib 3, conical pick is rotated at work more favourable, prevented the eccentric wear of conical pick effectively, prolonged the application life of conical pick greatly.
The utility model can be widely applicable for mining, on coal mining and the engineering machinery.
