Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rubber gasket stamping devices, in particular to a rubber gasket stamping device for automobile batteries. BACKGROUND

[0002] Plastic recycling refers to the process of collecting, classifying, processing and reprocessing waste plastic products to convert them into reusable materials or products. The core purpose is to reduce the pollution of plastic waste to the environment, save primary resources such as oil, and reduce energy consumption in the production process, which is an important part of circular economy. Because the rubber material has good elasticity and sealing property, after being crushed by the rubber recycling system, it can be used to produce regenerated rubber products, which can effectively block the moisture, dust, oil stains and other impurities in the outside world from entering the battery during the automobile manufacturing process.

[0003] Rubber has the characteristics of high elasticity, high toughness and easy deformation: if traditional blades are used for cutting, the rubber will stretch or contract due to elasticity when subjected to external force, resulting in uneven cutting and size deviation. The stamping device uses instantaneous impact force to complete the cutting of the stamping knife in a very short time. The inner and outer circles of the rubber gasket are in the shape of a back-to-back character, which makes it more likely for the cutting knife to stick to the tool during cutting. After the rubber gasket sticks to the tool, the rubber material will be stuck to the tool and move with the tool, causing the rubber at the bend to be stretched or torn, affecting the size accuracy and structural integrity of the product. In addition, the tool is relatively sharp, and the distance between the stamping knife and the rubber material to be cut is small, resulting in a narrow operating space when replacing the tool. The sharp blade can directly contact the skin, causing cuts and scratches. If the tool is not completely fixed or accidentally falls, it is more difficult to avoid in a narrow space, which may cause more serious mechanical injuries. SUMMARY

When the tool holder 24 needs to be replaced, the through strip 19 is used to achieve convenient unlocking, the through strip 19 is pushed to slide along the through groove 18, the extrusion groove 20 on the through strip 19 is in contact with the trapezoidal groove 17 of the protruding block 15, and since the trapezoidal groove 17 and the extrusion groove 20 are both inclined surfaces 16, the pushing force of the through strip 19 will be transmitted to the protruding block 15 through the inclined surface 16, forcing the protruding block 15 to overcome the elastic force of the telescopic spring one 14 and retract upward along the movable cavity one 13, and to be separated from the movable cavity two 23 of the wedge-shaped block 22, at this time, the tool holder 24 can be removed, realizing quick dismounting.

[0040] For details, please refer to Figures 1 to 5 and Figure 8The device further comprises an auxiliary pressing mechanism 25 arranged on the tool holder 24, the auxiliary pressing mechanism 25 comprising a fixed cover 29 fixedly installed at the bottom of the tool holder 24, a plurality of movable rods 32 arranged in a circumferential array being arranged on the fixed cover 29, a resisting block 33 fixedly installed at the bottom of each movable rod 32, and the auxiliary pressing mechanism 25 being used for pressing the cut rubber pad to prevent the rubber pad from sticking to the stamping cutter.

[0041] In the above embodiment, the rubber material has certain viscosity, and is easy to stick to the cutter due to intermolecular force after stamping and cutting. If the pad moves upward with the cutter, the position of the pad may be deviated when falling, resulting in error in the next stamping, or deformation and burr due to collision. The auxiliary pressing mechanism 25 continuously presses and delays separation, thereby avoiding sticking to the cutter and ensuring the integrity and consistency of each pad.

[0042] Further, the tool holder 24 is fixedly installed with a first stamping cutter 26 and a second stamping cutter 27, the first stamping cutter 26 and the second stamping cutter 27 are arranged in a character shape, the second stamping cutter 27 is located inside the first stamping cutter 26, and a plurality of notches 28 arranged in a circumferential array are arranged on the second stamping cutter 27. A plurality of movable holes 1 30 arranged in a circumferential array are arranged through the tool holder 24, a plurality of movable holes 2 31 arranged in a circumferential array are arranged on the fixed cover 29 at the bottom of the tool holder 24, the movable holes 2 31 are concentrically arranged with the movable holes 1 30 and have equal diameters. The movable holes 1 30 and the movable holes 2 31 are penetrated by the movable rods 32, the outer surfaces of the movable rods 32 are slidably connected with the inner walls of the movable holes 1 30 and the movable holes 2 31, and a fixed disc 34 is fixedly installed on the outer surfaces of the movable rods 32. A plurality of extension springs 2 35 are sleeved on the outer surfaces of the movable rods 32, the extension springs 2 35 are located between the fixed disc 34 and the fixed cover 29, and a limiting ring 36 is fixedly installed at the top of each movable rod 32.

[0043] In the above embodiment, when the tool holder 24 is lowered, the abutting block 33 at the bottom of the movable rod 32 first contacts the surface of the rubber pad, and the pre-compression force of the second telescopic spring 35 tightly presses the pad on the pad plate 3. At this time, the stamping knife has not contacted the rubber material to be cut, the tool holder 24 continues to descend, the second telescopic spring 35 is further compressed, the movable rod 32 slides upward relative to the tool holder 24, and the stamping knife one 26 and the stamping knife two 27 cut into the rubber, completing the cutting of the outer ring and the inner ring. When the tool holder 24 rises, the stamping knife one 26 and the stamping knife two 27 move upward with the tool holder 24, but the abutting block 33 still contacts the pad under the action of the elastic force of the second telescopic spring 35, the movable rod 32 slides downward relative to the tool holder 24, until the spring returns to the initial length, the abutting block 33 is completely separated from the pad, ensuring that the tool and the pad are completely separated, preventing sticking. When cutting, the buffer force provided by the compression of the spring avoids excessive extrusion of the abutting block 33 on the pad, which causes deformation; when separating, the delay effect of the spring rebound ensures that the abutting block 33 continues to press at the initial stage of the tool rising, breaking the adhesion force of the rubber and the tool.

[0044] Further, a screw rod 37 is arranged in the middle of the fixed cover 29, a threaded block 38 is threadedly connected to the outer surface of the screw rod 37, and the threaded block 38 is fixedly installed in the inner cavity of the fixed cover 29. In the above embodiment, through the combination of the screw rod 37 and the threaded block 38, the adaptability problem of the auxiliary pressing mechanism 25 when facing various types and specifications of rubber pads is solved, so that the same equipment can flexibly cope with different processing needs, while ensuring the stability of the stamping quality.

[0045] Through all the above embodiments, the working principle of the present application is:

[0046] The operator holds the tool holder 24, aligns the wedge block 22 of the connecting shaft 2 with the wedge-shaped slot 12, and inserts the wedge block 22. During the insertion process, the top of the wedge block 22 will press the bottom inclined surface 16 of the protrusion 15 in the connecting shaft 1. After the protrusion 15 is pressed, it slides upward along the movable cavity 1 and compresses the extension spring 1. At this time, the protrusion 15 temporarily retracts into the movable cavity 1. When the wedge block 22 is completely inserted and the outer surface of the wedge block 22 and the outer surface of the connecting shaft 1 are completely attached to the same horizontal line, the movable cavity 2 of the top of the wedge block 22 is aligned with the movable cavity 1 of the connecting shaft 1. The extension spring 1 releases the elastic force, pushes the protrusion 15 out and clamps it into the movable cavity 2. At this time, the protrusion 15 is firmly fixed with the wedge block 22 through axial clamping and radial constraint, and the tool holder 24 is firmly fixed. When the tool holder 24 needs to be replaced, the through strip 19 is used for convenient unlocking. The through strip 19 is pushed to slide along the through slot 18. The side of the extrusion slot 20 on the through strip 19 is attached to the trapezoidal slot 17 of the protrusion 15. Since the trapezoidal slot 17 and the extrusion slot 20 are both inclined surfaces 16, the pushing force of the through strip 19 is transmitted to the protrusion 15 through the inclined surface 16, forcing the protrusion 15 to overcome the elastic force of the extension spring 1, retracting upward along the movable cavity 1, and separating from the movable cavity 2 of the wedge block 22. At this time, the tool holder 24 can be removed, achieving quick disassembly, improving the replacement efficiency of the tool holder 24, reducing downtime, ensuring the firmness and stability of the installation of the tool holder 24, and improving the stamping precision;

[0047] Then the power supply of the device is started, and the output shaft 9 of the stamping cylinder 8 starts the downward operation. When the tool holder 24 descends, the bottom of the movable rod 32 contacts the rubber pad surface through the pre-compression force of the extension spring 2, and the pad is tightly pressed on the pad plate 3. At this time, the stamping knife 1 and the stamping knife 2 have not contacted the rubber material to be cut. The tool holder 24 continues to descend, the extension spring 2 is further compressed, the movable rod 32 slides upward relative to the tool holder 24, and the stamping knife 1 and the stamping knife 2 cut into the rubber to complete the cutting of the outer ring and the inner ring. When the tool holder 24 rises, the stamping knife 1 and the stamping knife 2 move upward with the tool holder 24, but the abutting block 33 still contacts the pad under the action of the elastic force of the extension spring 2, and the movable rod 32 slides downward relative to the tool holder 24 until the spring returns to the initial length, and then the abutting block 33 completely separates from the pad, ensuring that the tool and the pad are completely separated and preventing sticking. During cutting, the buffer force provided by the spring compression avoids excessive extrusion of the abutting block 33 on the pad, which causes deformation. During separation, the delay effect of spring rebound ensures that the abutting block 33 continues to press on the tool in the initial stage of the tool rising, breaks the adhesion between the rubber and the tool, and ensures the product integrity and production continuity.
