Abstract

The utility model provides a balanced structure of long rod form shaping drift of C type mouth, includes the drift, the drift is long rod form hollow structure, has seted up a C type mouth, its characterized in that along length direction at drift upper portion side: concave holes are additionally arranged at the C-shaped opening. Set up the shrinkage pool in drift side C type mouth, the shrinkage pool is apart from the up end 120mm to increased the equilibrium of drift, reduced the drift because long and thin drift that forms warp, reduced the waste of the mould that causes because the drift warp. The utility model has the advantages of simple and reasonable structure, it is effectual to take shape, has better solved the yielding problem of C type mouth stock form forming punch, and the life who effectively improves the mould is short, has not only practiced thrift the cost, has still improved product quality and production efficiency simultaneously.

Description

Balance structure of long rod-shaped forming punch of C-shaped opening

Technical Field

The utility model belongs to the technical field of powder metallurgy, a mould is related to, concretely relates to balanced structure of stock form forming punch of C type mouth.

Background

Powder metallurgy is a process technique for producing metal powder or metal powder (or a mixture of metal powder and nonmetal powder) as a raw material, and forming and sintering the raw material to produce metal materials, composite materials and various products, and is widely applied to various fields. Because the powder metallurgy has unique chemical composition, mechanical property and physical property, the powder metallurgy can not be obtained by the traditional fusion casting method, and can be used for manufacturing various powder metallurgy parts of automobiles, motorcycles, textile machinery, electric tools, hardware tools, electric appliances and the like.

The forming die is a key device in the production process of powder metallurgy products, iron powder for powder metallurgy is formed in the forming die by pressure, and the size of a formed piece is guaranteed by the size of a finished piece. Therefore, during the machining of the central ring-like part, the forming punch is an important tool to guarantee the precision of the product.

In the design of the conventional powder metallurgy forming punch, as shown in fig. 4, the forming punch 10 is thin and long, the punch is easy to deform in the using process, and the punches are generally scrapped without much quantity, so that the waste of a die is caused, and the working efficiency is reduced.

Therefore, a balanced structure of a long rod-shaped forming punch with a C-shaped opening is needed to reduce the deformation of the center ring punch and prolong the service life of the die.

Disclosure of Invention

The utility model aims to solve the technical problem that a simple structure is reasonable, the effectual balanced structure of stock form forming punch of C type mouth that takes shape is provided to foretell technical current situation to reduce the drift and warp, improve mould life.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a balanced structure of long rod form shaping drift of C type mouth, includes the drift, the drift is long rod form hollow structure, has seted up a C type mouth, its characterized in that along length direction at drift upper portion side: concave holes are additionally arranged at the C-shaped opening.

As an improvement, the concave hole is formed in the inner wall of the C-shaped opening, and the distance between the concave hole and the upper end face of the punch is 120 +/-10 mm.

Furthermore, two concave holes are formed in the inner walls of the two sides of the C-shaped opening respectively and symmetrically.

And finally, the concave hole is a semicircular hole with the aperture of 12 +/-1 mm.

Compared with the prior art, the utility model has the advantages of: set up the shrinkage pool in drift side C type mouth, the shrinkage pool is apart from the up end 120mm to increased the equilibrium of drift, reduced the drift because long and thin drift that forms warp, reduced the waste of the mould that causes because the drift warp. The utility model has the advantages of simple and reasonable structure, it is effectual to take shape, has better solved the yielding problem of C type mouth stock form forming punch, and the life who effectively improves the mould is short, has not only practiced thrift the cost, has still improved product quality and production efficiency simultaneously.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, 2 and 3, the balance structure of the long rod-shaped punch with the C-shaped opening comprises a punch 1, wherein the punch 1 is of a long rod-shaped hollow structure, a C-shaped opening 11 is formed in the side surface of the upper part of the punch 1 along the length direction, and a concave hole 12 is additionally formed in the C-shaped opening 11. Two concave holes 12 are symmetrically formed in the inner walls of the two sides of the C-shaped opening 11 respectively, and the distance L between each concave hole 12 and the upper end face of the punch 1 is 120 +/-10 mm; the concave hole 12 is a semi-circular hole with the aperture d of 12 +/-1 mm.

The utility model discloses through implementing the result of use good, and make the convenience, solved the problem that centre lopps formed the drift and warp betterly. After the punch balance structure is adopted, the size of a formed product can meet the requirement, the service life of a die is prolonged, the cost is saved, and the product quality and the production efficiency are improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
