Abstract
The utility model relates to a mining machine which is a bud-shaped alloy head cutting pick. In the utility model, hard alloy is designed into a structure whose middle part is formed into a circular table and a cone-shaped table, and a handle part of the utility model is formed into a taper shank. The utility model adopts two cone-shaped faces comprising the cone-shaped table and the taper shank for positioning and welding, and the positioning of the utility model are reliable, the bonding area of the utility model is enlarged, and the utility model can enhance connecting strength, bear lateral force and enhance the service life of cutting picks.
Description
The utility model belongs to mining facility, as the pick that mining machine adopted.
At present; domestic; in the pick that outer mining machine adopted; used hard alloy head can be divided into two types: the one, and the garden cylindricality; be welded on pick body front end center; another kind is a sheet; be welded on the upper surface of pick body; garden cylindricality carbide alloy is owing to be welded on pick body front end center; surround pick body mother metal all around; mother metal quick abrasion in the work reduces the bonding strength of carbide alloy and pick body greatly, and carbide alloy easily comes off from the pick body; then pick is scrapped; sheet carbide has the not frayed function of its rear portion pick body of protection when cut, but sheet carbide has only plane, its back and the welding of pick body, and its bonding strength is low; bear the ability of lateral force, also very easily come off.
The purpose of this utility model provides a kind of bonding strength that can improve carbide alloy and pick body, prevents the bud shape alloy head pick of carbide alloy early fallout.
The technical solution of the utility model is achieved in that carbide alloy is designed to bud shape, as shown in Figure 1, the carbide alloy upper end is a taper, Yi Yuantai is arranged below, connecting frustum below the platform of garden, be the shank of taper bottom, whole carbide alloy shape is like a bud, and two conical surfaces of the shank of its frustum and taper are even can locate welding.
Because it is garden platform and frustum structure that the utility model adopts the carbide alloy middle part, afterbody is less, and adopts the welding of two conical surfaces location, and the location is reliable, and bonding area is big.The bonding strength height, and can bear lateral force, can improve the application life of pick.
Fig. 1 is a bud shape carbide alloy pick structure chart.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
As shown in Figure 1, be bud shape carbide alloy pick, moulding carbide alloy 1 is welded on the pick body 2, moulding carbide alloy 1 is a bud shape, and the upper end is a taper point of a knife part, links to each other with the garden platform below, platform lower end, garden is connecting frustum, be taper shank bottom, two conical surfaces of its frustum and taper shank all can be located welding, and the location is reliable.
Claims (1)
1, a kind of moulding carbide alloy is welded on the bud shape alloy head pick that constitutes on the pick body, it is characterized in that moulding carbide alloy (1) for bud shape, and promptly the upper end is a taper, and Yi Yuantai is arranged below, is connecting frustum below the platform of garden, is the garden taper shank bottom.
