Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] refer to figure 1 , is a kind of powder metallurgy process disclosed by the present invention, comprises the following steps:

[0046] Step 1, mixing materials, uniformly mixing metal powder and lubricant according to the proportioning ratio to form raw material powder, ready for use;

[0047] Step 2: Blank molding, put the raw material powder that has been mixed in step 1 into the powder molding machine, and the powder molding machine sends the raw material powder into the preset product mold, and presses it into the blank of the product at room temperature, and takes it out to wait use;

[0048]Step 3, degreasing, heat the blank in step 2, use natural gas or propane to heat, keep the heating temperature below 400°C, preferably keep 250-400°C, and continue the heating time until all the lubrication in the blank is guaranteed When the workpiece is d...

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a powder metallurgy forming process. Background technique [0002] Powder metallurgy is a process technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. The powder metallurgy method has similarities with the production of ceramics, and both belong to the powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0003] The existing Chinese invention patent whose authorization notification number is CN107790724A can be referred to, ...
