Category powder is pressed into pie, then metallic article is made by sintering.
The quality of product is, it is necessary to carry out process of the rotation satisfaction in punching press to former when in order to meet powder metallurgy forming
Middle metal dust is evenly distributed.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of belt pulley powder metallurgy rotational forming mould, can solve
Certainly in general powder metallurgy product metal dust uneven the problem of causing poor product quality in metallurgical forming process.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of belt pulley powder metallurgy rotational forming
Mould, its innovative point are：Including former, negative template and fixed punching；The former is arranged in negative template, the fixed punch
Plate is arranged on the bottom of former and negative template；
It is provided with the former and accommodates the die cavity that metal dust coordinates formed product with drift, the die cavity is in cylinder knot
Structure；The chuck coordinated with negative template is provided with the side bottom outline of the former, and the bottom of former and negative template is neat
It is flat；A pair of first spring bases are vertically installed with the outer wall of the former；
The centre of the negative template is provided with the through hole coordinated with former, and receiving the is provided with the outer wall of the negative template
The level trough that one spring base passes through；First spring base can drive former to rotate in the horizontal direction along level trough；Described the moon
A pair of the second spring seats coordinated with the first spring base are provided with the outer wall of template；First spring base and second spring seat
Staggeredly in 90 degree of settings；The pair of first spring base one of them with a pair of second spring seats one of those by stretching bullet
Spring is connected, and another in a pair of first spring bases is connected with another of a pair of second spring seats also by extension spring；
The fixed punching is arranged on the bottom of former and negative template, is provided with fixed punching and accommodates the circle that drift passes through
Hole；The diameter of the circular hole is more than the diameter of die cavity and less than the diameter for the through hole for coordinating former on negative template.
Further, negative template is extended in one end of the former, extends on former and is set on one end outline of negative template
It is equipped with helical teeth.
Further, it is connected between the fixed punching and negative template by countersunk head screw thread.
Further, extend the helical teeth of negative template end set on the former and driven by gear.
The utility model has the advantage of：
1）, can be in powder metallurgy process by setting offsetting spring structure on former and negative template in the utility model
Middle rotation former causes metal dust to be distributed in die cavity more uniformly, and the product more homogeneous of formation is golden after pressing in addition
Belonging to powder can also be more convenient without hand-reset by extension spring reset.
