Abstract
The utility model relates to a welding-free combined type cutting tooth of a mining machine. A steel tooth sleeve (2) of an alloy tool is wrapped by a hard-alloy cutting tooth head (1) by adopting a hot-jacket process, and then the steel tooth sleeve (2) and the hard-alloy cutting tooth head (1) are pressed into a cutting tooth handle (3) together, so that the annealing of the cutting tooth handle (3) due to high welding temperature is overcome, hard support is provided for the periphery of the hard-alloy cutting tooth head to prevent falling and cracking, and further the service life of a product is greatly prolonged.
Description
Technical field
The utility model relates to the rapid wear accessory that a kind of mining machinery is used.
Background technology
At present, traditional pick causes the carbide alloy cutting pick head to reduce due quality and intensity because of welding high temperature, and because of the high annealing universal phenomenon that causes the carbide alloy cutting pick head easily to drop easy to wear that becomes, product is not long application life yet for the pick body.
Summary of the invention
The purpose of this utility model is to provide a kind of long-lived mining machinery to exempt from the box-like pick of soldering group.In order to solve owing to welding causes defectives such as the carbide alloy cutting pick head drops easily, bursts apart, the utility model is taked the structure with dual combination, be that alloy tool steel-tooth cover (2) wraps up carbide alloy cutting pick head (1) with hot cover process in the Figure of description, be pressed into pick handle (3) more together, cause the annealing of pick handle (3) thereby overcome by welding high temperature, making has had hard support around the carbide alloy cutting pick head and can not drop, burst apart.Thereby prolong product application life greatly.
The technical scheme that its technical problem that solves the utility model adopts is: the alloy tool steel-tooth cover (2) through hardening tightly wraps up carbide alloy cutting pick head (1) with hot cover process; fuse; and then be pressed into pick handle (3) together; thereby avoid welding the annealing that high temperature causes the pick handle; protection carbide alloy cutting pick head is injury-free, and the carbide alloy cutting pick head is prolonged application life greatly.
Description of drawings
Figure of description is a structural representation of the present utility model.
Reference numeral 1 is the carbide alloy cutting pick head among the figure,
Reference numeral 2 is an alloy tool steel-tooth cover,
Reference numeral 3 is pick handles.
The specific embodiment
The specific embodiment of the present utility model is that alloy tool steel-tooth cover 2 usefulness hot cover process are pressed into pick handle 3 more together to carbide alloy cutting pick head 1 parcel.Exempt from the box-like pick of soldering group with regard to the mining machinery of having finished dual combination like this.
Claims (1)
1. mining machinery is exempted from the box-like pick of soldering group, it is characterized in that: alloy tool steel-tooth cover (2) adopts hot cover process parcel carbide alloy cutting pick head (1), is pressed into pick handle (3) more together.
