Abstract
The utility model relates to a (pickaxe-shaped or knife-shaped) cutting pick with an alloy protective base, which is used for mine exploitation and drivage. The cutting pick comprises an alloy cuttinghead (2), a cutting pick base body (1) and the like, wherein the alloy cutting head (2) is welded at the top of the cutting pick base body (1) in the way of braze welding, and a wear resistance layer(3) is melted and covered on the periphery of the top of the cutting pick base body (1). The utility model is characterized in that the alloy cutting head (2) is in a crown-shaped step type, i.e. thefront end of the alloy cutting head (2) is in a shape of a cone or a polyhedral cone, a cylinder matched with the cutting pick base body (1) is arranged at the back end of the bottom of the cone, andthe diameter of the bottom of the cone is greater than that of the cylinder. The top edge of the cutting pick can be effectively protected, so the top edge of the cutting pick is not easy to be abraded, and the wear resistance layer at the top edge of the cutting pick can be effectively protected.
Description
Technical field
The utility model is that a kind of mining driving protects base (pick shape or knife-edge) pick with alloy.
Technical background:
Existing mining driving is a cylinder vertex of a cone shape with the alloy head of pick, and the soldering of alloy head is on the pick matrix, after the soldering; the alloy head is not less than 2.5mm apart from the pick body edges; even at pick body periphery cladding wearing layer, the pick top is very easily cracking or wearing and tearing also, thereby can't effectively protect the pick top; in use because of the matrix serious wear; make the alloy head drop, or wearing layer comes off, and cause pick to be scrapped; cause waste, and the ordinary production of influence driving.
Summary of the invention:
The purpose of this utility model is to provide a kind of alloy to protect basic pick shape or knife-edge pick for the mining driving; it can protect pick matrix top not easy to wear effectively; protect the pick top effectively; but in addition at the high or cladding wearing layer of pick matrix periphery hardness, the pick anti-wear performance is increased substantially again.
For achieving the above object, the technical scheme that the utility model is taked is: include alloy butt, pick matrix etc.Alloy butt soldering is at the top of pick matrix, higher or the cladding of the peripheral hardness at pick matrix top has wearing layer, it is characterized in that: the alloy butt is crown step, the front end that is the alloy butt is cone or multiaspect cone, be provided with the cylinder that cooperates with the pick matrix in the cone base rear end, the diameter of cone base is greater than cylindrical diameter.
Because alloy butt of the present utility model is designed to crown step; in use, also just can protect the pick top not easy to wear effectively, protect the pick top effectively; but in addition at the high or cladding wearing layer of pick matrix periphery hardness, the pick anti-wear performance is increased substantially again.
Description of drawings:
Accompanying drawing is the utility model schematic diagram.
The specific embodiment:
Accompanying drawing is an embodiment of the present utility model, includes alloy butt 2, pick matrix 1 etc.Alloy butt 2 solderings are at the top of pick matrix 1, higher or the cladding of the peripheral hardness at pick matrix 1 top has wearing layer 3, it is characterized in that: alloy butt 2 is crown step, the front end that is alloy butt 2 is cone or multiaspect cone, be provided with the cylinder that cooperates with pick matrix 1 in the cone base rear end, the diameter of cone base is greater than cylindrical diameter.
Because alloy butt 2 of the present utility model is designed to crown step, in use, also just can protect pick matrix top not easy to wear effectively, increases substantially the durability of pick.
Claims (1)
1, a kind of alloy protects basic pick, include alloy butt (2), pick matrix (1), alloy butt (2) soldering is at the top of pick matrix (1), hardness higher or peripheral cladding in pick body (1) top has wearing layer (3), it is characterized in that: alloy butt (2) is crown step, the front end that is alloy butt (2) is cone or multiaspect cone, is provided with the cylinder that cooperates with pick matrix (1) in the cone base rear end, and the diameter of cone base is greater than cylindrical diameter.
