Description

Technical Field

[0001] The utility model belongs to the technical field of stamping manufacturing, and particularly relates to a cleaning device for parts stamping waste. Background Art

[0002] The mass production of sheet metal parts mostly uses steel plates to be continuously stamped by a stamping machine. The punching part will produce a lot of small waste particles, which will be scattered on the mold and the stamping table during the continuous stamping process, causing uncontrolled damage to the mold and the product. Therefore, the collection of waste materials is a problem that technical personnel in this field need to solve.

[0003] The existing patent with publication number CN220144588U discloses a sheet metal stamping die cleaning device, including an upper die base, a lower die base, and a lower support plate. A hydraulic cylinder is arranged on the upper die base, a push rod is arranged under the hydraulic cylinder, and a forming ejector is arranged under the push rod. A waste cavity is opened on the lower die base, and a solenoid valve is arranged under the waste cavity. A vacuum pump is arranged on the lower support plate, a vacuum chamber is arranged on the vacuum pump, and a sealing cover is arranged on the side of the vacuum chamber. The vacuum chamber is connected to the vacuum pump through an air inlet pipe, and the waste chamber is connected to the vacuum chamber through a waste pipe.

[0004] The prior art has the following problems:

[0005] Because the raw materials for continuous stamping are mostly rolled steel strips, anti-rust oil is added during rolling to prevent the steel strips from rusting. This will cause the small particles of waste punched out to adhere to the waste pipe wall. Under the further adsorption of the solenoid valve, the adhesion of multiple small particles of waste will cause the waste pipe to be blocked, making it impossible for the vacuum chamber to effectively clean the waste.

[0012] In the utility model, the cleaning device also includes a bracket and a roller. The bracket is connected to the side of the lower workbench, and the bracket is rotatably connected to the gear; the roller is rotatably connected to the bracket, and the roller slides relative to the side of the rack away from the gear.

[0033] Example

[0034] Please refer to Figure 1-Figure 7 , Figure 1-Figure 7 An embodiment of the present application is shown.

[0035] This embodiment provides a device for cleaning waste from stamping parts, such as Figure 2As shown, it includes a magnetic shield 101, a U-shaped magnet 1, a main isolation plate 4 and a corrugated plate. The magnetic shield 101 is rotatably connected to the side of the lower workbench 8 of the punch press through a rotating shaft 102, and has an adsorption state and a separation state, as shown in FIG. Figure 5 As shown, when in the adsorption state, the opening of the magnetic shielding cover 101 faces the waste chute 502, as shown in FIG. Figure 4 As shown, when in the separated state, the opening of the magnetic shield 101 is away from the waste chute 502; Figure 4 As shown, the magnet 1 is clamped by two locking disks 106, the locking disk 106 is threadedly connected to the rotating shaft 102, the locking disk 106 is welded inside the magnetic shielding cover 101, and the adsorption end of the magnet 1 faces the opening of the magnetic shielding cover 101; Figure 2 and Figure 4 As shown, the main isolation plate 4 is connected to the side of the lower workbench 8, with one side of the main isolation plate 4 facing the magnet 1 and the other side facing the waste chute 502; the corrugated plate is welded to the side of the main isolation plate 4 facing the waste chute 502.

[0036] When using, Figure 3 As shown, the upper workbench 7 drives the upper die 6 to press down, and the punch 601 penetrates the die sleeve 501 to punch and cut the steel strip 9. The cut waste falls into the waste chute 502 set in the lower die 5, and then slides to the side of the workbench. When the upper workbench 7 descends, the magnetic shielding cover 101 is removed from the Figure 4 Status rotates to Figure 5 The waste is adsorbed to the side of the main isolation plate 4, and then the upper workbench 7 moves up while the magnetic shield 101 moves from Figure 5 Status rotates to Figure 4 state, the waste adsorbed on the side of the main isolation plate 4 falls down.

[0037] It should be noted that the magnetic shielding cover 101 uses conductive foam as the inner lining, and the conductive foam is a conductive braided sleeve wrapped around a foam core made of polyurethane or EPDM. The conductive braided sleeve is usually composed of silver-plated nickel nylon, aluminum foil or Monel wire (nickel-copper alloy) Ferrex (tin-plated copper-clad steel wire), and has good conductivity. The use of the magnetic shielding cover 101 cannot completely block the magnetic field generated by the magnet 1, but it will weaken it. At the same time, because the magnet 1 rotates with the magnetic shielding cover 101, the position with the strongest suction force at the center of the adsorption end of the magnet 1 is far away from the main isolation plate 4, which will also cause the waste on the main isolation plate 4 to fall because the suction force cannot offset the gravity; when other shaped magnets 1 except the U-shaped magnet 1 cannot keep the adsorption ends of the two magnets facing the opening of the magnetic shielding cover 101, it is sufficient to keep the adsorption end of one magnet facing the opening.

[0038] Through the above technical solution, a main isolation plate 4 is set between the magnet 1 and the waste chute 502 to reduce the adsorption force on the waste according to magnetic conduction; the use of corrugated plates can prevent the anti-rust oil from causing the waste to stick to the main isolation plate 4 and prevent it from falling.

[0039] As a preferred implementation method, Figure 2 As shown, the cleaning device also includes a gear 2 and a rack 3. The gear 2 is connected to the smooth part of the rotating shaft 102 through the pin block 201 and then rotatably connected to the lower workbench 8. The gear 2 is transmission-connected to the magnetic shielding cover 101; the rack 3 is connected to the upper workbench 7 of the punch press and meshes with the gear 2; when the upper workbench 7 is pressed down, the rack 3 moves downward to drive the gear 2 to drive the magnetic shielding cover 101 to rotate so that the opening faces the waste chute 502. When the upper workbench 7 is lifted, the rack 3 moves upward to drive the gear 2 to drive the magnetic shielding cover 101 to rotate counterclockwise so that the opening is away from the waste chute 502.

[0040] It should be noted that, according to the stroke of different molds, the gear 2 can be set to provide different transmission ratios of the gear set to meet the rotation angle range of the magnetic shield 101; the magnet 1 rotates to Figure 5 In the state shown, the suction force of the magnet 1 can avoid pulling the steel strip 9 and causing misalignment.

[0041] Through the above technical solution, the gear 2 and the rack 3 are used to drive the magnetic shielding cover 101 to change its state by utilizing the relative movement of the upper and lower workbenches, thereby improving the automation of adsorption and separation.

[0042] As a preferred implementation method, Figure 2 and Figure 6 As shown, the cleaning device also includes a bracket 103 and a roller 105. The bracket 103 is screwed to the side of the lower workbench 8. The bracket 103 is rotatably connected to the gear 2 through the rotating shaft 102 and is limited by the pin block 201; the two rollers 105 are connected to the mounting frame 104 through bearings, and the mounting frame 104 is connected to the bracket 103. The rollers 105 slide relative to the side of the rack 3 away from the gear 2.

[0043] It should be noted that the mounting frame 104 is made of a tough metal sheet and has an impact resistance effect. If necessary, a buffer device such as a damping spring is used.

[0044] Through the above technical solution, the roller 105 is used to support the rack 3, which ensures the driving rigidity of the rack 3 and improves the driving stability of the rack 3.

[0045] As a preferred implementation method, Figure 4 and Figure 7As shown, the cleaning device also includes a mounting seat 401, which is connected to the side of the main isolation plate 4 facing away from the magnet 1, and the mounting seat 401 is detachably connected to the T-slot provided in the lower workbench 8 through a T-screw.

[0046] During installation, if Figure 7 As shown, the main isolation plate 4 is connected to the sides of the two mounting seats 401 through screws and mounting columns, and is connected to the side of the lower workbench 8 through four mounting columns.

[0047] Through the above technical solution, the mounting base 401 is used to increase the connection stability of the main isolation plate 4 and improve the ability of the main isolation plate 4 to resist the adsorption of the magnet 1.

[0048] As a preferred implementation method, Figure 7 As shown, the cleaning device also includes a collecting groove 403, which is welded above the four mounting columns below. The collecting groove 403 is a V-shaped groove with an open lower end, and the side of the collecting groove 403 is inclined from bottom to top away from the waste chute 502.

[0049] When in use, when the magnetic shielding cover 101 is in the adsorption state, the waste is attracted to the main isolation plate 4 by the adsorption end of the magnet 1. After switching to the separation state, the waste falls, gathers in the middle through the collection groove 403, and is finally collected at the opening below the collection groove 403 using a cloth belt or a collection box.

[0050] It should be noted that due to the suction of the magnet 1, the sheet-like waste will be adsorbed on the main isolation plate 4 in parallel. Due to the presence of the corrugated plate, no surface contact will occur, only point contact will occur. After losing the suction of the magnet 1, the falling sheet-like waste will remain parallel to the main isolation plate 4 and fall to the inclined surface of the collecting trough 403, which is more conducive to rolling.

[0051] Through the above technical solution, the collection trough 403 is used to collect the waste dropped from the main isolation plate 4, thereby reducing the waste scattering range and improving the convenience of collecting the waste.

[0052] As a preferred implementation method, Figure 4 As shown, the cleaning device also includes an additional isolation plate 402, which is welded to the upper end of the main isolation plate 4, and the additional isolation plate 402 is inclined 45 degrees from bottom to top toward the magnet 1.

[0053] Through the above technical solution, the isolation plate 402 is used to prevent the splashing waste from being adsorbed by the magnet 1 when the magnetic shielding cover 101 rotates, thereby increasing the range of magnetic adsorption and reducing the splashing of waste.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
