Abstract
The utility model discloses a powder metallurgy drift, this drift is formed by a plurality of independent single drift combinations, and every single drift includes drift main part and drift installation base, and drift installation base sets up in the non-work end of drift main part, and a plurality of independent single drifts pass through drift installation base and assemble on the mould gland. After the split punch of the utility model is adopted for production, the size of the product can be effectively controlled, the die material is saved in the selection of the die material, and the deformation can be compensated in a targeted manner, so that the product quality is practically improved, and the die manufacturing cost is saved; through production verification, the utility model is adopted for the lower punch, the product size is controlled stably, the service life of the die is prolonged, and the cost of the die is greatly reduced.
Description
Technical Field
The utility model belongs to the field of machinery, concretely relates to powder metallurgy drift.
Background
In the existing product with a multi-step structure, the design of a powder metallurgy die generally has two or even three lower punches (generally called as lower second punch and lower third punch), the length of the punch needs to be longer when multiple sets of punches are used, and particularly when the sectional area of individual steps of the product is small, the strength of the product usually has congenital defects, namely easy fracture and multiple deformation. The engineer designs are also difficult to achieve in selecting materials for desired results. The material with good wear resistance can prolong the service life of the die, but the toughness of the material cannot be simultaneously achieved, and the die is easy to break; the wear resistance of the die material with better toughness is greatly reduced, the die is easy to wear, product defects can be caused, product cracks can be generated in serious cases, and continuous or discontinuous generation can be realized in the actual production process, so that the production is greatly unsmooth.
The existing mould design mode only needs a small section of fracture or deformation, the whole mould needs to be scrapped, and the cost is relatively wasted. The local density difference of the product is inconsistent, which may cause the local deformation of the mold to be large, and it is a great challenge to ensure the parallelism of the product.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a powder metallurgy punch head, which solves the problem that a slender mould is easy to break, thereby improving the use defect of the slender structure mould in production; the abnormal process can be corrected in time conveniently, the scrappage of the die is reduced, and the die cost is saved.
In order to achieve the above object, the present invention provides the following technical solutions:
a powder metallurgy punch is formed by combining a plurality of independent single punches, each single punch comprises a punch body and a punch mounting base, the punch mounting base is arranged at the non-working end of the punch body, and the independent single punches are assembled on a die gland through the punch mounting bases.
Further, the number of the single punches is three.
Furthermore, the outer ring of the punch mounting base is of a one-third arc-shaped structure, and the outer periphery of the punch mounting base is combined into a circular structure after three independent single punches are combined.
Furthermore, the inner ring of the punch mounting base is of a one-third arc-shaped structure, and a hollow circular structure is formed inside the punch mounting base after the three independent single punches are combined.
Furthermore, the single punch and the die gland are assembled in a detachable installation mode.
Has the advantages that: the utility model provides a powder metallurgy drift, this drift has following advantage:
1. after the split punch of the utility model is adopted for production, the size of the product can be effectively controlled, the die material is saved in the selection of the die material, and the deformation can be compensated in a targeted manner, so that the product quality is practically improved, and the die manufacturing cost is saved;
2. through production verification, the utility model is adopted for the lower punch, the product size is controlled stably, the service life of the die is prolonged, and the cost of the die is greatly reduced.

Detailed Description
The present invention is further described below with reference to specific examples, which are only exemplary and do not limit the scope of the present invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.
A powder metallurgy punch is formed by combining three independent single punches 1, each single punch 1 comprises a punch body 11 and a punch mounting base 12, the punch mounting base 12 is arranged at the non-working end of the punch body 11, and a plurality of independent single punches 1 are assembled on a die gland 2 through the punch mounting bases 12.
The outer ring of the punch mounting base 12 is of a one-third arc-shaped structure, and the outer periphery of the punch mounting base is combined into a circular structure after three independent single punches 1 are combined.
The inner ring of the punch mounting base 12 is of a one-third arc-shaped structure, and a hollow circular structure is formed inside the punch mounting base after three independent single punches 1 are combined.
The single punch 1 and the die gland 2 are assembled in a detachable mounting mode.
The utility model designs the punch separately, which area has a problem during production, and compensates in which area, even if one punch is damaged, a small part can be replaced at once, and the whole mould is not required to be scrapped, thus not only solving the problem that the size is not easy to control, but also improving the problems of mould deformation, local density difference of products and the like; the split punch is convenient to manufacture and the cost is far lower than that of an integral punch.
Claims (2)
