Abstract
The utility model discloses a powder metallurgy decompression swing block which comprises a C-shaped ring, mounting holes formed at the two ends of the C-shaped ring respectively and a limiting slot, wherein the C-shaped ring is a component mainly using powder metallurgy; a reinforcing boss is arranged on the back of the limiting slot on the C-shaped ring; and wear-resistant composite layers are arranged on the inner wall of the mounting hole and the surface of the limiting slot. Through the utility model, the structural strength at the limiting slot on the C-shaped ring is obviously improved, the utilization rate of the material is high, the working hours and the material cost are saved, the internal stress is low, and the wear resistance and service life of the decompression swing block can be obviously improved.
Description
Technical field
The utility model relates to a kind of decompression and gets rid of piece, and more particularly, the utility model relates to and a kind ofly adopts the decompression of powder metallurgy process manufacturing to get rid of piece.
Background technology
It is abnormity component that piece is got rid of in decompression, and shape matching is complicated, and the decompression of prior art is got rid of piece and is generally medium carbon steel or steel alloy, forms through processing, heat treatment, because its shape matching is complicated, so the part processing capacity is large, and waste of material is also more, and material cost is higher; Stopper slot one end wall of C shape ring is thick thinner, and intensity is relatively poor, stopper slot fatiguability fracture in the use; Because it is C shape annular component, produce easily internal stress after the heat treatment, therefore, easily the hardness of working surface can not be too high for installing hole inwall, stopper slot etc., causes these surfaces not wear-resisting; Even like this, after the heat treatment, decompression is got rid of piece and is still existed no small internal stress.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of stopper slot place intensity of C shape ring high, and technique is simple, and stock utilization is high, and wearability is good, and piece is got rid of in the powder metallurgy decompression that internal stress is little.
The utility model is achieved through the following technical solutions technical goal.
Piece is got rid of in the powder metallurgy decompression, comprises C shape ring, lays respectively at installing hole, stopper slot that C shape is encircled two ends, and its improvements are: described C shape ring is the member take powder metallurgy as main body; The back side of described C shape ring upper limit position groove is provided with the reinforcement boss; Described installing hole inwall, stopper slot surface are provided with wear-resistant composite bed.
The further technical scheme of the utility model is: the described wear-resistant composite bed rare earth compound composite bed that is.
The utility model further technical scheme is: described wear-resistant composite bed thickness is 0.1-2.4mm.
The utility model compared with prior art has following good effect:
1, the back side of C shape ring upper limit position groove is provided with and strengthens the structural strength that boss has significantly improved C shape ring upper limit position groove place.
2, adopt the powder metallurgical technique preparation, only need a small amount of machining, stock utilization is high, saves man-hour and material cost.
3, installing hole inwall, stopper slot surface are provided with wear-resistant composite bedly, need not heat treatment, can because heat treatment produces internal stress, can not significantly improve wearability and service life that piece is got rid of in decompression simultaneously.

Fig. 2 is that the D of Fig. 1 is to view.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 is the A-A cutaway view of Fig. 1.
Fig. 5 is that the C of Fig. 2 is to view.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment.
Piece is got rid of in powder metallurgy decompression shown in the drawings, comprises C shape ring 2, lays respectively at installing hole 1, stopper slot 3 that C shape is encircled 2 two ends, and C shape ring 2 is the members take powder metallurgy as main body, and the back side that C shape is encircled 2 upper limit position grooves 3 is provided with reinforcement boss 5; It is the rare earth compound composite bed that installing hole 1 inwall, stopper slot 3 surfaces are provided with wear-resistant composite bed 4, preferred wear-resistant composite bed 4, and thickness is 0.1-2.4mm, and in the present embodiment, wear-resistant composite bed 4 thickness are 1mm.
The back side that C shape is encircled 2 upper limit position grooves 3 in the utility model is provided with strengthens boss 5, has significantly improved the structural strength that C shape is encircled 2 upper limit position grooves, 3 places; The preparation of employing powder metallurgical technique only needs a small amount of machining, and stock utilization is high, saves man-hour and material cost; Installing hole 1 inwall, stopper slot 3 surfaces are provided with wear-resistant composite bed, need not heat treatment, can because heat treatment produces internal stress, not significantly improve simultaneously wearability and service life that piece is got rid of in decompression.
