Abstract
The wear-resisting type pick of the present invention, belongs to engineering machinery specific purpose tool and manufactures, and product includes: denticle and tooth head.It is characterized in that: the upper plane at taper denticle sets one group of groove with the decussation of certain depth, coordinate with the convex purlin phase melting welding of the decussation with certain altitude being located at carbide button head bottom.Set a circular port post at the center of denticle groove simultaneously, coordinate with the cylinder phase melting welding being located at Chi Toutulin center.Denticle material is structural alloy steel, makes through Cold Forging.Tooth head material is hard tungsten-cobalt alloy, is processed into through forge hot.
Description
[art] engineering machinery specific purpose tool manufactures
The pick of the churning driven that [state of the art] current excavation is used, its basic structure is made up of with carbide button head two parts metal pick body, and the denticle being in use positioned at around tooth head easily weares and teares.In order to improve its service life, at present, many products have been welded with a number of bar shaped hard metal tip again after denticle bulk heat treatmet completes on the denticle of carbide button head periphery, the wearability overall to increase pick.But, because of rotation, to dig tooth crest be pyramidal structure, and no matter the number of antifriction alloy piece is how many, still can not well protect denticle, not only complex process, and relatively costly.
[goal of the invention] present invention provides the carbide button head that a kind of novel cross is inlayed, and is not fallen by mill, extends the service life of product, reduce manufacturing process, reduce and produce and use cost after protecting the abrasion of carbide button head denticle around.
The cross of [content of the invention] present invention is inlayed pick and is included: denticle and tooth head.It is characterized in that: the upper plane at taper denticle sets one group of groove with the decussation of certain depth, coordinate with the convex purlin phase melting welding of the decussation with certain altitude being located at carbide button head bottom.Set a circular port post at the center of denticle groove simultaneously, coordinate with the cylinder phase melting welding being located at Chi Toutulin center.
Described denticle material is structural alloy steel.Make through cold forging.
Described tooth head material is hard tungsten-cobalt alloy, makes through forge hot.
The cross of the present invention inlays pick technique simply, with low cost, is suitable for batch production.
[embodiment] accompanying drawing is embodiments of the invention, and Fig. 1 is the pick front view of the present invention, and Fig. 2 is the pick top view of the present invention, and Fig. 3 is carbide button head schematic diagram.In Fig. 1, Fig. 2, Fig. 3,1), denticle, 2), jump ring, 3), tooth head, 4), denticle groove, 5), denticle hole post, 6), the convex purlin of tooth head, 7), tooth head cylinder.
