Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a powder metallurgy stainless steel flange manufacturing method, which can solve the need to clamp it with the aid of clamps in the existing flange painting process, but the gap between the clamp and the flange There are many contact surfaces, so that the flange plate in this part cannot be sprayed, and it needs to be repainted after adjusting its position later. The operation process is complicated, and the position of the existing paint layer may be damaged when adjusting the position. Due to the small internal space of the bolt holes of the flange, it is often difficult to spray the interior of the flange when spraying paint, etc.

Embodiment Construction

[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0038] Such as Figure 1 to Figure 7 As shown, a powder metallurgy stainless steel flange manufacturing method, the specific manufacturing method is as follows:

[0039] S1. Powder molding: feeding stainless steel powder into the mold for compression molding to obtain flange blanks;

[0040] S2. Sintering: Vacuum sintering the flange blank, and obtain a compact flange molding after cooling;

[0041] S3, jacking up and fixing: put the formed flange plate into the spray booth 4, the center hole of the formed flange plate is located on the jacking device 5, and the jacking device 5 su...

Abstract

The invention provides a method for manufacturing a powder metallurgy stainless steel flange. The operation is completed by the cooperation of a base, a hydraulic pump, a material frame, a paint spray booth, a jacking device and a material spray pipe. During the process, it needs to be clamped with the help of a fixture. However, there are many contact surfaces between the fixture and the flange, so that the flange at this part cannot be sprayed, and it needs to be adjusted for a second time after adjusting its position. Touch-up painting is a complex operation process, and the position of the existing paint layer may be damaged when the position is adjusted. Because the internal space of the bolt hole of the flange is small, it is often difficult to spray the interior of the flange when spraying paint.

Description

technical field [0001] The invention relates to the field of powder metallurgy stainless steel, in particular to a method for manufacturing a powder metallurgy stainless steel flange. Background technique [0002] Powder metallurgy stainless steel is stainless steel manufactured by powder metallurgy method. It is a powder metallurgy material that can be made into steel or parts. Its advantages are to reduce segregation of alloy elements, refine microstructure, improve performance, save raw materials, and save energy consumption. , to reduce costs, among them, the stainless steel flange is made by powder metallurgy method, after the flange is made, it needs to be painted on the surface, so as to prevent the flange from being corroded and damaged during use. However, the following problems often exist in the existing surface treatment: [0003] 1. During the painting process of the flange, it is necessary to clamp it with the aid of a fixture. However, there are many contact ...
