Abstract
The utility model relates to a novel pen-shaped head press-in pick. In the aspect of material, the pick adopts alloy tool steel to replace the hard alloy; and in the aspect of structure, a pen-shaped pick head (01) is directly pressed into the welding-free structure of a pick handle (02), namely, mechanical fit is used for replacing the welding structure of the hard alloy head. The pen-shaped pick head is subjected to surface seepage treatment to greatly improve the hardness and abrasion resistance of the pick head so as to replace the traditional pick welded with the hard alloy head.
Description
Technical field
The utility model relates to the rapid wear instrument that a kind of mining machinery is used.
Background technology
At present, traditional pick with the welding hard alloy head mine, excavation operation.Because the high temperature that produces in the operation and the annealing of weld make it very easily to wear and tear, thereby cause hard alloy head to come off easily, application life is not long.
Summary of the invention
In order to overcome the problem that hard alloy head drops easily.The utility model adopts alloy tool steel to replace carbide alloy on material; Structurally, exempt from welded construction, be press-fitted the welded construction that replaces hard alloy head by machinery with the pen type head.And use the surface seepage technology, increase the hardness and the abrasion resistance of tooth head surface.Thereby reach purpose than welded hard alloy head pick longer service life.
The technical scheme that its technical problem that solves the utility model adopts is: tooth head (01) directly is pressed into denticle (02), thereby avoids welding the annealing that high temperature causes; The planform of tooth head (01) adopts straight pen type simultaneously, has avoided stress to concentrate, and has overcome defectives such as bursting apart, fall tooth, has improved application life greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein figure number 01 is the pen type cutting pick head.
The specific embodiment
Pen type tooth head (01) directly is pressed into denticle (02), promptly becomes the forced pick of pen type head.
Claims (1)
1. the forced pick of pen type head is to be pressed into the novel pick that denticle (02) forms by tooth head (01), it is characterized in that the planform of tooth head (01) is a pen type.
