Embodiment Construction

[0006] A method for forming a stainless steel filter and a connecting insert. First, a cylindrical stainless steel filter and a connecting insert are manufactured. The stainless steel filter has a cylindrical upper end opening, and the connecting insert has cylindrical openings at both ends. The size ratio of the circular joint of the insert is 1.02:1.0;

[0007] The connection insert is matched with the round joint of the powder filter, and is sintered in a vacuum sintering furnace according to the conventional powder metallurgy product sintering method; after cooling, the connection piece can be threaded with different specifications according to the needs to obtain a stainless steel filter that can be widely used.

Abstract

The invention overcomes the shortcomings that as a stainless steel filter has holes and is lower in density, threads can not be formed according to the method that the stainless steel filter and an insert are matched in proportion before being sintered and closely connected for formation after being sintered, and after formation, a connection insert can achieve thread processing. Therefore, the stainless steel filter can be in flexible connection with other fittings after being combined with the insert, the filter can be applied to connecting parts in different specifications and wide application is realized.

Description

technical field [0001] The present invention is a combination of comprehensive powder metallurgy technology and traditional machining technology, which can produce stainless steel filters with cylinders with different specifications of 2-100 microns and can be flexibly connected closely with other accessories to filter air and liquid. Background technique [0002] With the wide application of powder metallurgy products, especially in corrosive liquids and air, filter devices with good anti-corrosion performance and durability are required to play the role of filtering and damping. The manufacturing method of the powder stainless steel filter and the insert molding of the present invention solves the limitation that powder metallurgy low-density products cannot be tapped, and expands the application field of the powder filter. Contents of the invention [0003] The manufacturing method of powder stainless steel filter and insert molding of the present invention overcomes t...
