Problems solved by technology

[0004] In the actual production process, powder metallurgy mainly presses metal powder into a specific complex shape, so that the processing efficiency is fast, but the surface of the product processed by powder metallurgy is not as bright as the product processed by chipping, and the outer surface is too rough, so it will be processed again. Chip machining to obtain a bright appearance is not only a waste of time, but also the structure of the product manufactured by powder metallurgy is peculiar, and a specific fixture needs to be set, which further increases the processing cost
The above-mentioned production process cannot solve this problem

Embodiment 1

[0037] Embodiment 1: Reference figure 1, a powder metallurgy production line, including a powder hydraulic molding machine 1, a calciner 2, a cooling device 3, a vibration polishing machine 4 and a screening machine 5 arranged in sequence. First, after the metal powder is configured, it is extruded into a corresponding shape through the powder hydroforming machine 1 and a customized mold, and then a conveyor belt is set between the powder hydroforming machine 1 and the calciner 2, and the workpiece is transferred to the calciner through the conveyor belt Calcination is carried out in 2 to eliminate the internal stress of the workpiece. The calcined workpiece is cooled by the cooling device 3, and then put into the vibration polishing machine 4 for polishing, so that the surface of the workpiece is bright, and finally passes through the screening machine 5, so that the workpiece and the steel ball can be separated. The cooling device 3 is a cooling box, which adopts water cool...

Embodiment 2

[0051] Embodiment two, a kind of powder metallurgy production process, comprises the following steps:

[0052] (1) Mix different metal powders evenly;

[0053] (2) Stamp the mixed metal powder into the shape of the product with a powder forming hydraulic press;

[0054] (3) After the product is formed, put the product into the calciner for sintering;

[0055] (4) Cool the product after sintering;

[0056] (5) The cooled product is put into a vibration polishing machine for polishing;

[0057] (6) The polished products are packaged and put into storage.

Description

technical field [0001] The invention relates to the field of metallurgical production and processing, more specifically, it relates to a powder metallurgy production line and a production process. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. After the metal powder is calcined and shaped, it needs to be polished. The vibration polishing machine is the equipment used to polish the surface of the workpiece. [0003] The Chinese patent with the publication number CN106041090A discloses a production process of powder metallurgy lock cylinder head pulling, the specific steps are as follows: S1: raw material pretreatment, S2: batching, S3: mixing, S4: compression molding, S5: pressure sintering , S6: cooling out of the oven, S7: machining, S8: packaging. [0004] In the actual producti...
