Abstract
The utility model relates to a reinforced-type cutting pick, which comprises a cutting pick core part, wherein the front end of the cutting pick core part is fixedly connected with a cutting pick head part, and the reinforced-type cutting pick is characterized in that: an anti-abrasion layer is welded on the surface of the cutting pick head part, and the anti-abrasion layer is an alloy coating layer. The reinforced-type cutting pick is welded by a laser welding device, the alloy wrapped part on the cutting pick head part can produce 1500 DEG C to 2000 DEG C within 0.1s, alloy powder is welded on the cutting pick head part to increase the abrasion resistance, so when the reinforced-type cutting pick is matched with the alloy, the same abrasion can be realized; and since the instantaneous high temperature is free from being harmful on the cutting pick parent material, the flexibility of the cutting pick core part can be maintained, and at the same time because of the high hardness of the alloy and the alloy coating layer, no spark is produced when the cutting pick is collided with the rock. The service life of the reinforced-type cutting pick is two times to three times of that of a traditional cutting pick.
Description
Technical field
The utility model relates to the mining machine accessory, is specifically related to a kind of reinforced pick.
Background technology
We run into hard rock f 〉=5 in the mining area pick uses, the a large amount of consumption of pick causes under the productivity ratio, the frequent pick of changing has increased direct labor's labour intensity, strengthened cost of ton coal greatly, how to address this problem? this is that vast for a long time pick manufacturer is all in the problem of constantly exploring.We know that hard rock will use mild alloy, just will reduce hardness of alloy, with prevent alloy with the sharp impacts of rock in cracked, just can't accomplish wear-resistingly but alloy rigidity can not improve, this is implacable contradiction seemingly.And also often occurred alloy in actual use and do not ground off, the part of pick clad alloy has been worn and torn totally, and pick is crash still.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of abrasion resistance good, the reinforced pick of long service life.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of reinforced pick comprises the pick core, and described pick core front is fixedly connected with the pick head, it is characterized in that: described pick head surface soldered has wearing layer.
Described wearing layer is the alloy-coated layer.
The beneficial effects of the utility model are: the utility model uses laser welding apparatus to carry out soldering, in 0.1 second, produce 1500-2000 ℃ at pick head alloy covered section, alloy powder is welded on the pick head increases abrasion resistance, it is mated in alloy accomplish same specific wear; Because moment, high temperature can not produce injury to the pick mother metal, the toughness that has kept the pick core, simultaneously because the high rigidity of alloy and alloy-coated layer, being does not almost have spark to produce in the collision of rock, application life of the present utility model be traditional pick 2-3 doubly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of reinforced pick comprises pick core 1, and pick core 1 front end is fixedly connected with pick head 2, and pick head 2 surfaces adopt laser welding apparatus to be welded with wearing layer 3, and wearing layer 3 is the alloy-coated layer.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a reinforced pick comprises the pick core, and described pick core front is fixedly connected with the pick head, it is characterized in that: described pick head surface soldered has wearing layer.
2. a kind of reinforced pick according to claim 1 is characterized in that: described wearing layer is the alloy-coated layer.
