Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air filter element processing, in particular to a heat-sealed air filter cutting device. Background Art
[0002] The air filter element is a kind of filter, also called air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms.
[0003] Traditional air filter elements are produced through heat sealing process, which will leave extra corners around the produced filter elements and need to be manually cut and removed, which is very time-consuming and labor-intensive, greatly reducing the production efficiency of air filter elements. Utility Model Content
[0004] The utility model aims to remedy the defects of the prior art and provide a heat-sealed air filter cutting device.
[0005] The utility model is realized by the following technical solutions:
[0006] A heat-sealed air filter cutting device comprises a backing plate, a cutting die and a hydraulic press. An air filter limiting groove is opened on the backing plate. The cutting die comprises a knife holder. A cutting knife is fixed at the lower end of the knife holder. The shape and size of the cutting knife are the same as the outer edge of the air filter. The backing plate is located on the working table of the hydraulic press. The heat-sealed air filter is placed at the position of the air filter limiting groove of the backing plate. The cutting die is placed on the air filter. The cutting die is pressed down by the hydraulic press to perform edge cutting.
[0007] The air filter limiting groove, the knife holder and the cutter are all square, and the corners are all arc-shaped transitions.
[0008] An air filter positioning plate is provided on the inner wall of the lower end of the tool holder, a screw mounting plate is fixed inside the tool holder, a plurality of screws are fixed on the air filter positioning plate, a return spring is sleeved on each screw, a plurality of screw through holes are correspondingly opened on the screw mounting plate, and the upper ends of the screws pass through the screw through holes.
[0009] The knife die is a steel knife die.
[0010] The utility model has the advantages that the utility model places a pad with an air filter limiting groove on a hydraulic press work surface, places a hot-pressed air filter on the pad, places a die cutter, starts the hydraulic press for cutting, cuts off excess edges and corners, has accurate positioning, is easy to operate, saves time and effort, and has high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 This is a schematic diagram of the structure of the utility model without the hydraulic press;
[0012] Figure 2 It is a top view of the utility model;
[0013] Figure 3 This is a schematic diagram of the knife die structure of the utility model. DETAILED DESCRIPTION
[0014] like Figure 1 , 2 As shown in Figure 3, a heat-sealed air filter cutting device includes a backing plate 1, a knife die 2 and a hydraulic press. An air filter limit groove is opened on the backing plate 1. The knife die 2 includes a knife holder 21. A cutter is fixed at the lower end of the knife holder 21. The shape and size of the cutter are the same as the outer edge of the air filter 3. The backing plate 1 is located on the workbench of the hydraulic press. The heat-sealed air filter 3 is placed at the position of the air filter limit groove of the backing plate 1. The knife die 2 is placed on the air filter 3. The knife die 2 is pressed down by the hydraulic press to cut the edges. The air filter limit groove, knife holder 21 and cutter are all square, and the corners are all arc-shaped transitions. An air filter positioning plate 22 is provided on the inner wall of the lower end of the tool holder 21, a screw mounting plate 23 is fixed inside the tool holder 21, a plurality of screws 24 are fixed on the air filter positioning plate 22, a return spring 25 is sleeved on each screw 24, a plurality of screw through holes are correspondingly opened on the screw mounting plate 23, and the upper ends of the screws 24 pass through the screw through holes.
[0015] The cutter die 2 is a steel cutter die, the cutter is relatively sharp and has a good cutting effect.
[0016] When in use, place the pad 1 with the air filter limiting groove on the work surface of the hydraulic press, place the hot-pressed air filter 3 on the pad 1, limit it through the air filter limiting groove, place the cutting die 2, wherein the air filter positioning plate 22 is sleeved on the outside of the raised part of the air filter, and the width of the air filter positioning plate 22 is the width of the edge part that needs to be left for the air filter. Start the hydraulic press, press down the cutting die 2, and cut. The cutter cuts off the excess corners. After cutting is completed, it returns to its original position under the action of the return spring 25, and the return spring also has a buffering effect.
