Abstract
The utility model discloses an extrusion punch with abrasion resistance and high temperature resistance. The extrusion punch is applied to a metal inner cavity extrusion molding mould. The extrusion punch comprises a punch basal body, wherein a hardening layer formed by supersonic speed flame spraying covers the punch basal body. Due to the hardening layer, the performances of the high temperature resistance, high pressure resistance and the abrasion resistance of the extrusion punch are improved, and the hardening layer also can be used for spraying after being abraded, so that the waste of materials is effectively reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of machining equipment field, especially a kind of extruding drift that is applied in the metal inner cavity extrusion molding dies.
Background technology
In the metal inner cavity extrusion forming process, the extruding drift pushes the metal in the metal inner cavity, forms the part identical with the metal inner cavity shape, makes the internal structure of metal product and surface quality more perfect.Because in the extrusion process, the operating ambient temperature of extruding drift is high, pressure is large, therefore high to extruding drift quality requirement, need the extruding drift can be high temperature resistant, high pressure and require the extruding drift wear-resisting.
Present existing extruding drift generally adopts expensive alloy die steel to make, and after Multi-step forming, wearing and tearing, so that the wearing and tearing of staking punch are very serious, causes the life-span of staking punch very short, and waste of material is serious.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is that a kind of high temperature resistant, high pressure and wear-resisting extruding drift will be provided.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of extruding drift of Wear-resistant, high-temperature resistant comprises a drift matrix, and described drift matrix surface also covers the hardened layer that one deck adopts HVAF to form.
Concrete, described drift matrix adopting alloy die steel is made.
Preferably, the end of described extruding drift side also is provided with the fin that some and vertical direction are 10 ° of angles.
Further, described fin is along the circumferential direction evenly setting, and is equally divided into two parts: the fin in 180 ° of scopes is tilted to the left, and is positive 10 ° of angles with vertical direction; Fin in 180 ° of other scopes is tilted to the right, and is negative 10 ° of angles with vertical direction.
Preferably, also comprise a boss, described boss is located at the end face of described extruding drift.
With respect to prior art, extruding drift described in the utility model forms one deck hardened layer by the flame-spraying technology at the drift matrix surface, high temperature resistant, high pressure and the wear-resisting performance of extruding drift have not only effectively been improved, and after these hardened layer wearing and tearing, can also again spray the new hardened layer of one deck, improve utilization rate and the service life of extruding drift, reduced the waste of material.
In order to understand fully the purpose of this utility model, feature and effect, be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation.
Description of drawings
Fig. 1 is the utility model perspective view;
Fig. 2 is front view of the present utility model;
Among the figure:
1-drift matrix; 11-hardened layer; 12-boss; 13-fin.
The specific embodiment
As depicted in figs. 1 and 2, a kind of extruding drift of Wear-resistant, high-temperature resistant comprises a drift matrix 1, and the appearance of this drift matrix 1 has covered the hardened layer 11 that one deck adopts HVAF to form.
The HVAF technology is a kind of novel surface protection and surface intensified technique, is widely used in the engineering field of metal surface.It mainly utilizes flame as thermal source, and metal or nonmetallic materials are heated to molten condition, forms the high speed spray under the promotion of high velocity air, is ejected on drift matrix 1 surface.After the small melt granules that sprays strikes the surface of drift matrix 1, produce plastic deformation, form the hardened layer 11 of the stacked deposition of sheet.The new hardened layer that produces 11 is very strong with the surface conjunction ability of drift matrix 1, can reach the instructions for use of secondary extrusion drift fully.In order further to improve the high temperature resistant and anti-wear performance of drift matrix 1, this drift matrix 1 can also adopt alloy die steel to make.
See also Fig. 1, the upper end of this extruding drift side also is provided with some and vertical direction is 10 ° fin 13, in order to improve the extrusion performance of extruding drift, this fin 13 is for along the circumferential direction evenly arranging, and be equally divided into two parts: the fin 13 in 180 ° of scopes is tilted to the left, and is positive 10 ° of angles with vertical direction; Fin 13 in 180 ° of other scopes is tilted to the right, and is negative 10 ° of angles with vertical direction.The end face of this extruding drift also is provided with a boss 12, conveniently pushes drift and carries out extruding work.
With respect to prior art, extruding drift described in the utility model forms one deck hardened layer 11 by flame-spraying surface hardening technique on drift matrix 1 surface, high temperature resistant, high pressure and the wear-resisting performance of extruding drift have not only effectively been improved, and after these hardened layer wearing and tearing, can also again spray the new hardened layer of one deck, improve utilization rate and the service life of extruding drift, reduced the waste of material.
More than describe preferred embodiment of the present utility model in detail, the ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all in the art technical staff according to the utility model design on the prior art basis by logic analysis, reasoning or according to the available technical scheme of limited experiment, all should be among the determined protection domain by these claims.
