Embodiment approach

[0039] The third embodiment of the present invention provides a small-diameter porous filter cartridge manufacturing process for filters. Put the processed porous plate into the above-mentioned filter cartridge pressing tool, first press along the middle, and then rotate the hole Plate, press the two straight sides respectively to obtain porous semicircular tubes, put the two porous semicircular tubes into the above-mentioned filter cartridge assembly tooling for assembly, and then perform spot welding to group and position the two porous semicircular tubes. Then team up and position two porous semicircular pipes for welding.

[0040] In one or more examples of this embodiment, the pressed porous semicircular tube is inspected and corrected.

[0041]In this series of embodiments, a tape measure is used to inspect the pressed porous semicircular tube, and a wooden hammer is used to correct the large deviation of the ellipticity. Use a wooden hammer to correct the local ellipti...

Embodiment 1

[0048] Cartridge pressing tooling, such as Figure 1~2 As shown, it includes a hydraulic press, a pressing die (2) and a forming die (1). The forming die (1) is assembled and welded by forming a half pipe (1.1) and a connecting support plate (1.2). The specification of the forming half pipe (1.1) is The length is 1600mm, and the size of the connecting support plate (1.2) is 60mm×100mm×δ12mm; the pressing mold (2) is assembled and welded by the pressing round tube (2.1) and the connecting piece (bending machine tool) (2.2), and the pressing round tube ( 2.1) The specifications are Length 1550mm.

[0049] Cartridge assembly tooling, such as Figure 3-4 As shown, it is assembled and welded by a support frame (3) and a pair module (4). The support frame (3) is assembled and welded by support channel steel 1 (3.1), support channel steel 2 (3.2), and support angle steel (3.3), and the specifications of support channel steel 1 (3.1) and support channel steel 2 (3.2) are [ 12. T...

Abstract

The invention discloses a manufacturing process of a small-diameter porous filter cartridge used for filters. The processed porous plate is put into the filter cartridge pressing tool, firstly pressed along the middle, and then the hole plate is rotated to carry out two straight sides respectively. Press to obtain the porous semicircular tube, put the two porous semicircular tubes into the filter cartridge assembly tooling for assembly, then perform spot welding, position the two porous semicircular tubes in a team, and then position the two porous semicircular tubes in the team The tubes are welded, the filter cartridge pressing tooling and filter cartridge assembly tooling are all as described in the instructions. The invention can not only improve the manufacturing efficiency of the filter cartridge, but also effectively control the ellipticity of the filter cartridge to meet the use requirements.

Description

technical field [0001] The invention belongs to the technical field of filter manufacturing, and relates to a manufacturing process of a filter cartridge, in particular to a manufacturing process of a small-diameter porous filter cartridge used for a filter. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] The filter is an indispensable device on the pipeline of the conveying medium, and is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, constant water level valve, and other equipment of the Fanggong filter. After the filter has a filter cartridge of a certain specification, the impurities are blocked. When cleaning is required, ju...
