Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, and specifically relates to a splash-proof device for a punching machine. Background Technique

[0002] Automobile parts are an important part of an automobile. Some automobile parts need to be processed using a punching machine during processing.

[0003] For example, a punching machine with the patent number CN218532596U includes a punching machine body, and also includes a blanking device and a product detection device. The signal output end of the product detection device is connected to the emergency stop switch and the blanking device control of the punching machine body. The punching machine body is located within the working area of the blanking device and the working area of the product detection device. However, the above document still has deficiencies. During use, it can automatically detect whether the product after punching by the punching machine meets the pre-designed dimensions, and can separate defective products and good products, solving the problem that the current punching machine can only produce products but cannot determine whether the produced products meet the preset standards. However, when the punching machine in the above document performs punching, the punching impact force is huge, and there will be flying debris, which poses a threat to the safety of the staff. At the same time, when producing automobile parts, there are many styles of automobile parts. Different molds need to be used when processing and punching different automobile parts. The mold in the above document is fixed, so it is not convenient to punch different automobile parts. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of flying debris, and a splash-proof device for a punching machine is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a splash-proof device for a punching machine, including a machine body and a sleeve. The sleeve is fixedly connected inside the machine body. A hydraulic cylinder is fixedly connected inside the machine body. The hydraulic rod of the hydraulic cylinder is fixedly connected with a top plate. A splash-proof mechanism is arranged on the outer wall of the top plate. A bottom plate is placed inside the machine body. A positioning mechanism is arranged above the bottom plate. A lower mold is fixedly connected to the upper surface of the bottom plate.

[0007] Preferably, the splash-proof mechanism includes cross bars. Both cross bars are fixedly connected to the outer wall of the top plate. A first rack is fixedly connected below the cross bars. The first rack is meshed with a gear. The gear is meshed with a second rack. The outer wall of the second rack is slidably connected with a bracket. The bracket is fixedly connected to the outer wall of the machine body. The bracket and the gear are rotatably connected through a bearing. Transparent plates are fixedly connected to the surfaces of the second racks on the left and right sides.

[0009] Preferably, a sliding rod is fixedly connected above the top plate, and the outer wall of the sliding rod is slidably connected to the sleeve.

[0010] Preferably, an upper mold is attached to the lower surface of the top plate.

[0011] For a splash-proof device of a stamping machine proposed by the present utility model, the beneficial effects are as follows: Through the cooperation among the cross bar, the first rack, the gear, the second rack, the bracket and the transparent plate, when the top plate drives the upper mold to move downward, it also drives the two cross bars to move. The cross bar drives the first rack to move, the first rack drives the gear to rotate, the gear drives the second rack to slide, and while the two second racks slide upward inside the bracket, they drive the transparent plate to move upward. The upper mold and the lower mold both come into contact with the automotive parts to be stamped to stamp the automotive parts. At this time, the transparent plate is in front of the stamping position, and when debris splashes, the transparent plate blocks the debris, avoiding the threat to the safety of the staff caused by the splashing debris.

[0012] Through the cooperation among the frame, the screw rod, the runner, the threaded block and the pressing plate, the runner drives the screw rod to rotate, the screw rod drives the threaded block to move, the threaded block drives the pressing plate to slide, the pressing plate separates from the lower mold, and the lower mold is removed for replacement. When the runner is rotated in the reverse direction, the pressing plate is in close contact with the lower mold to fix the lower mold, completing the replacement of the lower mold. Using the same method to replace the upper mold, both the upper mold and the lower mold can be replaced, thereby facilitating the stamping of different automotive parts. Description of the Drawings

The transparent plates 306 are made of tempered plastic.

[0025] The top plate 6 drives the upper die 9 to move downward and simultaneously drives the two cross bars 301. The cross bars 301 drive the first rack 302 to move. The first rack 302 drives the gear 303 to rotate. The gear 303 drives the second rack 304 to slide. While the two second racks 304 slide upward inside the bracket 305, they drive the transparent plate 306 to move upward. Both the upper die 9 and the lower die 8 are in contact with the automotive part to be stamped to stamp the automotive part. At this time, the transparent plate 306 is in front of the stamping position. When debris splashes, the transparent plate 306 blocks the debris to avoid threatening the safety of the staff due to the splashing debris.

[0026] The positioning mechanism 4 includes a frame 401, a screw 402, a runner 403, a threaded block 404, and a pressing plate 405.

[0027] The runner 403 drives the screw 402 to rotate. The screw 402 drives the threaded block 404 to move. The threaded block 404 drives the pressing plate 405 to slide. The pressing plate 405 is separated from the lower die 8, and the lower die 8 is removed for replacement. Rotate the runner 403 in the reverse direction, and the pressing plate 405 is in close contact with the lower die 8 to fix the lower die 8. The replacement of the lower die 8 is completed. Use the same method to replace the upper die 9. Both the upper die 9 and the lower die 8 can be replaced, thus facilitating the stamping of different automotive parts.

[0028] Working principle:

[0029] When using the anti-splash device of the stamping machine to process automotive parts, place the automotive part to be stamped above the lower die 8.

[0030] Automotive part stamping stage:

[0031] Start the hydraulic cylinder 5. The hydraulic cylinder 5 drives the top plate 6 to move downward. The top plate 6 drives the upper die 9 to move downward and at the same time drives the two cross bars 301 to move. The cross bars 301 drive the first rack 302 to move. The first rack 302 drives the gear 303 to rotate. The gear 303 drives the second rack 304 to slide. While the two second racks 304 slide upward inside the bracket 305, they drive the transparent plate 306 to move upward. The upper die 9 and the lower die 8 both contact the automotive parts to be stamped to stamp the automotive parts. At this time, the transparent plate 306 is in front of the stamping position. When debris splashes, the transparent plate 306 blocks the debris, avoiding the threat of the splashing debris to the safety of the staff. After the stamping of the automotive parts is completed, reverse-start the hydraulic cylinder 5. The top plate 6 moves upward, and the transparent plate 306 moves downward in the opposite direction of the above movement to remove the stamped automotive parts;

[0032] Replacement stage of the upper die and the lower die:
