Abstract
The utility model provides a wear -resisting tamping pickaxe of alloy cladding, including pick (a), pick body (b), pickaxe palm (d) and connection pick body (b) and pickaxe palm's (d) pick neck (c), its characterized in that: pick neck (c) and the surperficial cladding of pickaxe palm (d) have carbide. This wear -resisting tamping pickaxe of alloy cladding not only in the surface cladding of the pickaxe palm of tamping pickaxe the carbide piece, still in the pick neck surface cladding of tamping pickaxe the carbide piece, increased substantially the wearability of pick neck, prolonged the life of tamping pickaxe.
Description
Technical field
This utility model relates to tamping pickaxe used by rail track area of maintenance, the New-type wear-resistant alloy tamping pickaxe of especially a kind of alloy-coated.
Background technology
At present, national line safeguards that tamping pickaxe used is divided into two kinds: a kind of built-up welding tamping pickaxe being to slap build-up wear-resistant layer tamping pickaxe pick, the another kind of alloy wear-resisting tamping pickaxe slapping brazing hard alloy sheet tamping pickaxe pick.Wherein, built-up welding tamping pickaxe anti-wear performance is poor, and service life is shorter, makes mileage firm by ramming lower than 100 kilometers；And alloy tamping pickaxe is good due to the hard alloy wear resistance performance of surface soldering, so long service life, making mileage firm by ramming is more than 300 kilometers, reduces the labor intensity of workman.
A kind of Novel alloy tamping pick for welding of CN201530964U patent disclosure, uses the alloy sheet of 7 kinds of specifications to be attached to tamping pickaxe pick palm face；The CN204097807U patent disclosure wear-resisting tamping pickaxe of railway special metals of a kind of improvement, is characterized in that slapping leading portion soldering umbrella alloy tamping pickaxe pick.
The alloy-coated of alloy tamping pickaxe soldering is at the pick palm of steel matrix tamping pickaxe, and the cervical region of tamping pickaxe (pick neck) uncoated antifriction alloy, and according to on-the-spot situation of making firm by ramming, in time using distance more than 300 kilometers, the most severe place of abrasion is exactly the cervical region of tamping pickaxe, it can be said that the inefficacy of alloy tamping pickaxe is primarily due to what the abrasion of tamping pickaxe cervical region caused.
Utility model content
The purpose of this utility model is to provide a kind of wear-resisting tamping pickaxe of alloy-coated, and this tamping pickaxe can be greatly improved the service life of tamping pickaxe.
This utility model is adopted the technical scheme that by realizing its goal of the invention: a kind of wear-resisting tamping pickaxe of alloy-coated, and including the pick neck of pick, pick body, the pick palm and connection pick body and the pick palm, it is structurally characterized in that: described pick neck and pick palm Surface coating have hard alloy.
This utility model not only slaps Surface coating hard metal tip the pick of tamping pickaxe, and also hard metal tip on the pick neck Surface coating of tamping pickaxe, is greatly improved the wearability of pick neck, extends the service life of tamping pickaxe.
Further, the matrix of the wear-resisting tamping pickaxe of alloy-coated described in the utility model is wrought alloy steel.
In this manner it is ensured that the bulk strength of tamping pickaxe.
Further, pick neck described in the utility model and pick palm surface are coated with hard alloy by brazing mode.
The structure property of mother metal is affected little by the mode of soldering, and stress is little with deformation, and productivity ratio is high, and joint surface quality is good.
Further, the forging cross sectional shape of pick neck described in the utility model is hexagon.
So, the forging Surface coating hard metal tip at pick neck is conducive to.
Further, pick neck described in the utility model and pick palm Surface coating have the concrete mode of hard alloy to be: the surface soldering of pick neck and the pick palm is coated with polylith hard metal tip.
Further, the profile of specification shape and pick neck and the pick palm that pick neck described in the utility model and pick slap surface coated hard metal tip adapts.
Further, pick neck described in the utility model and pick slap surface coated hard metal tip ten kinds of specifications.
As such, it is possible to reached the purpose making the pick palm of tamping pickaxe and pick neck cover hard metal tip by simple layout designs, and produce with being conducive to high-volume scale, reduce production cost.
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
