Description

Technical Field

[0001] This utility model relates to the technical field of punching and cutting the lip of a sealing component, and in particular to an automatic punching and cutting device with follow-up feeding applied to the lip of a sealing component. Background Technology

[0002] Automotive seals are among the most important components of a car, widely used in doors, windows, body, sunroof, engine compartment, and trunk. The cross-sectional shape, lip length, lip thickness, cut size, and cut quality of the seals significantly affect the quality of installation and the driving experience. To improve the quality of seal notch machining and reduce processing costs, automotive seal suppliers at all levels need to optimize their manufacturing processes.

[0003] Traditional sealing lip punching fixtures either push the fixture to the theoretical punching position along the sealing material feeding direction using a servo feed system, or manually insert the sealing material into the fixture. These two feeding methods are not ideal for sealing materials with long cuts and a distance between the cut and the end. During feeding, the lip will come into contact with and rub against the cutter and die, generating resistance, which can cause feeding difficulties, scratch the surface of the sealing strip, affect the position and size of the cut, and result in long operation times.

[0026] The bottom of the wedge block 18 has a protrusion at one end near the feed drive cylinder 13, and there is an arc-shaped surface between the protrusion and the bottom of the wedge block 18.

[0027] The lower part of the frame 15 has an n-shaped structure, and the anvil mounting block 17 is rotatably installed between the two side plates of the n-shaped structure.

[0029] The lower part of the n-shaped side plate of the frame 15 is detachably mounted on the side wall of the movable seat 14 by bolts.

[0030] Upper and lower punching units 2 Figure 4 , Figure 5 As shown, the machine includes a lifting plate 21 that is slidably mounted on one side of the frame 15. A support plate 22 is fixed to the top of the lifting plate 21. The support plate 22 is located directly above the anvil 19. A punching drive cylinder 23 is fixed on the support plate 22. The telescopic rod of the punching drive cylinder 23 is connected to a cutter fixing seat 24. A pressing block 25 is provided below the cutter fixing seat 24. A connecting spring 26 is fixed between the top of the pressing block 25 and the bottom of the cutter fixing seat 24. A guide rail 27 is provided on one side of the lifting plate 21 corresponding to the cutter fixing seat 24 and the pressing block 25. The cutter fixing seat 24 and the pressing block 25 are slidably mounted on the guide rail 27. An upper cutter 28 is fixed to the bottom of the cutter fixing seat 24. The upper cutter 28 passes through the inside of the pressing block 25. A lower cutter 29 is installed on the lower side of the lifting plate 21. The upper cutter 28 is located above the anvil 19 and the lower cutter 29 is located below the anvil 19.

[0031] The bottom of the cutter holder 24 is provided with a limiting piece 210.

[0032] An extension plate 211 is provided on the upper side of the lifting plate 21 facing away from the cutter fixing seat 24. A vertical clearance channel is provided on the upper part of the frame 15 corresponding to the extension plate 211. The extension plate 211 passes through the vertical clearance channel and is equipped with a limit post 212. A limit block 213 is fixed on the frame 15, and the limit post 212 is located directly below the limit block 213.

[0033] An obstacle avoidance structure is provided between the lifting plate 21 and the chopping board mounting block 17. For example, an obstacle avoidance channel can be opened on the lifting plate 21 for the chopping board mounting block 17 to pass through, or a through hole can be opened on the chopping board mounting block 17 for the lifting plate 21 to pass through.

[0034] The working principle of the feed avoidance follow-up unit 1 is as follows:

[0035] First, install the seal 3 onto the reinforcing plate, by... Figure 2 It can be seen that the initial position of the tooling is far from the seal 3. The ball head of the spring plunger 110 uses the force of the spring to lift the anvil mounting block 17 around the rotating shaft 16 at a certain angle so that the anvil 19 can be inserted into the cutting position of the seal 3 later. When the work starts, the feeding drive cylinder 13 extends and pushes the moving seat 14, the frame 15 and the upper and lower punching units 2 on it to the left. When the feeding drive cylinder 13 pushes the upper and lower punching units 2 to the specified distance, the cam bearing 112 just contacts the wedge 18. The feeding drive cylinder 13 continues to push the upper and lower punching units 2 to the left, and the cam bearing 112 begins to lift the wedge 18 to rotate around the rotating shaft 16. Finally, the feeding drive cylinder 13 completes its stroke and skillfully rotates the anvil 19 into the cutting position of the seal 3. Figure 3 As shown.

[0036] Since the natural state of the lip of the seal 3 is curved upward, if the material feeding avoidance follow-up unit 1 is not developed, and the anvil 19 is directly pushed horizontally into the cutting position, the anvil 19 will definitely squeeze the lip and cannot enter the cutting position.

[0037] The working principle of the upper and lower punching units 2 is as follows:

[0038] After the cutting board 19 enters the cutting position of the seal 3, the punching drive cylinder 23 extends, pushing the cutter fixing seat 24, the upper cutter 28, and the pressure block 25 downward along the guide rail 27. After the pressure block 25 contacts the cutting board mounting block 17, the pressure block 25 stops moving downward, and the punching drive cylinder 23 continues to extend, pushing the cutter fixing seat 24 and the upper cutter 28 to continue moving downward. The upper cutter 28 begins to punch the cutting on the seal 3. When the limiting plate 210 hits the upper surface of the pressure block 25, the upper cutter 28 completes the punching. The punching drive cylinder 23 continues to extend. At this time, due to the fixing effect of the pressure block 25, the lifting plate 21 and the lower cutter 29 begin to move upward, starting to punch the cutting on the seal 3. When the limiting post 212 hits the limiting block 213, the punching is completed.

[0039] Of course, the feed drive cylinder 13 of the horizontally pushing upper and lower punching unit 2 can be replaced with a servo motor drive. The servo motor can be controlled by a program, and the start and stop positions can be controlled. Furthermore, the cam bearing 112 can be removed and replaced with a cylinder that pushes the anvil mounting block 17 to rotate around the rotating shaft 16. The sequence of actions is as follows: first, the servo motor feeds the material to a specified distance and stops; then, the newly added cylinder pushes the anvil mounting block 17 to rotate around the rotating shaft 16, allowing the anvil 19 to rotate and flatten the upturned lip. After that, the servo motor continues to feed to the punching position, and then the punching action is performed.

[0040] This invention effectively improves upon the problems of difficult material feeding and scratching of the sealing surface of traditional tooling. Furthermore, the simultaneous upper and lower punching structure allows one tooling to make two cuts, saving costs, optimizing the original tooling mechanism, resulting in higher product quality, faster work efficiency, and meeting customers' high requirements for product quality.

[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
