Description
Technical Field
The utility model relates to a cold isostatic pressing technical field especially relates to a powder metallurgy pipe plain bumper device.
Background
In the powder metallurgy process, the large-size tube blank is charged before cold isostatic pressing, and the outer sleeve of the die is mostly made of polyurethane or silica gel and other materials, so that the material is soft, and the size precision of the blank and the uniform distribution of the material are difficult to ensure in the charging and vibrating processes of the material. In the process of vibration compaction, because the force conducted by the vibration platform is not uniform, the conditions of mold displacement, inclination and the like can occur, and therefore, the distribution of materials in the mold is not uniform. This result is difficult to observe before sintering the billet, but during the powder sintering process, the billet shrinks at high temperature, so that the wall thickness of the large-size tube blank is uneven, and side bending occurs. Therefore, the charging before cold isostatic pressing is uniform, the influence on large-size tube blanks is huge, the size distribution of formed pressed blanks is irregular, the flatness is poor, the consistency of the pressed blanks is poor, the batch production is not facilitated, and the powder metallurgy tube blank compacting device is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a powder metallurgy pipe plain bumper device.
The utility model discloses a realize through following technical scheme: the utility model provides a powder metallurgy pipe plain bumper device, includes vibration platform and mould constraint mechanism, the vibration platform upper surface is fixed with the guide post, the mould constraint mechanism sets up on the guide post and coaxial with the guide post, mould constraint mechanism includes mould overcoat and mould steel core, and mould overcoat bottom is provided with the trompil that suits with the guide post size.
The utility model discloses technical scheme's further improvement lies in: the inner diameter of the die outer sleeve is matched with the outer diameter of the die, and the die outer sleeve is made of rigid materials.
The utility model discloses technical scheme's further improvement lies in: the guide post comprises a cylinder and a circular truncated cone, and the circular truncated cone and the end, far away from the vibration platform, of the cylinder are fixedly connected.
The utility model discloses technical scheme's further improvement lies in: the vibration platform comprises a vibration plate and a vibration motor, the vibration motor is arranged below the vibration plate, and an elastic part is arranged between the vibration motor and the vibration plate.
The utility model has the advantages that: the vibration platform produces the powder in the vibration plain bumper mould, and the guide post retrains the vibration direction of mould and fixes the mould, and the mould overcoat plays the restraint effect to the mould and avoids the material inhomogeneous in the mould distribution, guarantees that the material can not the deviation appear in feeding and plain bumper in-process size, and the mould overcoat adopts rigid material to help retraining the mould, and the guide post sets up the round platform and helps the direction of mould constraint mechanism.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a vibration platform; 2. a guide post; 3. sleeving a mold sleeve; 4. the mould steel core.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in the figure, the utility model provides a powder metallurgy pipe plain bumper device, tie the mechanism including vibration platform and mould, the vibration platform upper surface is fixed with the guide post, the mould tie the mechanism setting on the guide post and coaxial with the guide post, the mould ties the mechanism and includes mould overcoat and mould steel core, and mould overcoat bottom is provided with the trompil that suits with the guide post size. And the top of the mold outer sleeve is provided with a plug for fixing the mold and the mold outer sleeve.
In a further embodiment, the inner diameter of the mould jacket is adapted to the outer diameter of the mould, said mould jacket being made of a rigid material.
In a further embodiment, the guide post comprises a cylinder and a circular truncated cone, and the circular truncated cone and one end, far away from the vibration platform, of the cylinder are fixedly connected.
In a further embodiment, the vibration platform comprises a vibration plate and a vibration motor, the vibration motor is arranged below the vibration plate, and an elastic element is arranged between the vibration motor and the vibration plate. Vibrating motor includes vertical vibrating motor and horizontal vibrating motor, provides horizontal direction and vertical direction vibration respectively, and the elastic component helps supporting the preparation that the vibration board adapts to different weight pipe billets and can also obtain more stable vibration effect.
The utility model discloses a theory of operation is: before feeding, put into the mould overcoat earlier with the mould, can ensure that the material can not appear the deviation at the in-process size of feeding and jolt ramming, the guide post can tie the vibrations direction of mould at the in-process of jolt ramming to and the effect of fixed mould.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
