Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing ultrapure lined PTFE storage tanks, in particular to a device for post-processing and polishing an ultrapure lined PTFE storage tank after integral compression molding. Background Art

[0002] Integral pressing technology is a manufacturing process that is usually used to produce parts with complex shapes and dimensional accuracy requirements. In the manufacture of ultra-pure lined PTFE (polytetrafluoroethylene) storage tanks, the tank body of the ultra-pure lined PTFE storage tank needs to be polished after integral pressing to ensure that the required dimensional accuracy and surface finish are achieved.

[0003] According to a Chinese patent, a grinding device for stainless steel storage tanks, with publication number CN219053818U, includes a base, a rotating table, a grinding bar, a connecting rod, and a bracket. A first rotating shaft is welded to the bottom of the rotating table, a clamping hydraulic cylinder is welded to the upper end of the rotating table, and the tank body is clamped inside the clamping hydraulic cylinder. The bottoms of the left and right ends of the connecting rod are fixedly connected to mounting brackets. The lower end of the mounting bracket is rotatably connected to a two-way lead screw. One end of the two-way lead screw passes through the mounting bracket and is welded to a rotating head. A connecting block is welded to the top of the grinding bar. The upper surfaces of the left and right ends of the bracket are fixedly connected to a lifting hydraulic cylinder. The middle of the bracket is rotatably connected to a second rotating shaft. A second motor is installed on the top of the bracket. The bottom of the second rotating shaft passes through the bracket and is fixedly connected to the upper surface of the connecting rod. By using two grinding bars in a group, the inner and outer surfaces of the tank body can be polished synchronously, with high polishing efficiency. The relative rotation between the tank body and the grinding bars can improve the polishing efficiency and polishing quality.

[0004] In this device, the tank body is clamped on a rotating table by a clamping hydraulic cylinder, and two grinding bars are close to the tank body for grinding. However, the grinding bars generate a lot of dust during the grinding process. If the dust is not collected and treated in time, it can easily cause environmental pollution and be easily inhaled by operators, affecting their health. Therefore, a device for post-processing and grinding of ultra-pure PTFE-lined storage tanks is proposed. Utility Model Content
