Description

Technical Field

[0001] The utility model relates to the technical field of washer processing, in particular to an automatic washer stamping device. Background Art

[0002] Rubber washers have properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. They can be directly cut into sealing gaskets of various shapes and are widely used in industries such as medicine, electronics, chemical industry, antistatic, flame retardant, and food.

[0003] The utility model with the application number CN202122811962.3 discloses a washer stamping device. By arranging an air jet head inside the annular cutter and a blanking groove below the annular cutter, after the annular cutter cuts off the waste material, the air jet head blows out an air flow to blow the cut waste material into the blanking groove and drop it into the recycling box, automatically completing the cleaning of the waste material without the need for manual cleaning.

[0004] The above device forms a washer by cutting off the rubber at the center of the circular rubber pad through an annular cutter. The circular rubber pad is generally processed from a rubber sheet and needs to be processed twice to become a washer. It requires manual feeding, resulting in low work efficiency. Moreover, during cutting, accurate positioning cannot be achieved, the cutting position is prone to deviation, and the position of the central hole of the washer is prone to deviation, reducing the finished product quality.

[0005] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model

In addition, in the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0026] The present utility model provides a kind of automatic washer stamping device as Figure 1-5 shown, which includes a processing platform 1. A U-shaped bracket 2 is installed on the processing platform 1. An outer ring cutter 3 is arranged above the processing platform 1. Guide sliding rods 4 are installed on both sides of the outer ring cutter 3. The side of the guide sliding rod 4 away from the outer ring cutter 3 is slidably connected to the U-shaped bracket 2. A stamping cylinder 5 is installed on the U-shaped bracket 2. The telescopic end of the stamping cylinder 5 is fixedly connected to the guide sliding rod 4. A fixed through hole 6 is arranged at the center of the top of the outer ring cutter 3. A fixed bracket 7 is installed on the top of the outer ring cutter 3. A telescopic cylinder 8 is installed on the fixed bracket 7. The telescopic end of the telescopic cylinder 8 passes through the fixed through hole 6 and extends into the outer ring cutter 3. An inner ring cutter 9 is installed on the telescopic end of the telescopic cylinder 8. A fixed ring 10 is installed on the inner wall of the outer ring cutter 3. A sliding ring 11 is slidably connected in the outer ring cutter 3. A plurality of telescopic springs 12 are installed between the sliding ring 11 and the fixed ring 10. A sliding circular plate 13 is slidably connected in the inner ring cutter 9. A connecting spring 14 is arranged in the inner ring cutter 9.

[0027] The rubber sheet is conveyed on the processing platform 1. After the material is conveyed under the outer ring cutter 3, the stamping cylinder 5 starts to work. The telescopic end of the stamping cylinder 5 extends into the driving guide slide rod 4 and slides along the C-shaped bracket 2. The guide slide rod 4 drives the outer ring cutter 3 to descend, and the material is cut by the outer ring cutter 3. During cutting, the sliding ring 11 contacts the material, and the sliding ring 11 applies pressure to the telescopic spring 12. After the telescopic spring 12 is subjected to pressure, it deforms and contracts, and the sliding ring 11 rises along the inner wall of the outer ring cutter 3. The sliding ring 11 presses on the cut material. At the same time, the telescopic cylinder 8 starts to work. The telescopic end of the telescopic cylinder 8 extends into and drives the inner ring cutter 9 to descend. The inner ring cutter 9 cuts the material to form a washer. The sliding circular plate 13 presses on the cut waste material. The sliding circular plate 13 applies pressure to the connecting spring 14. After the connecting spring 14 is subjected to pressure, it deforms and contracts, and the sliding circular plate 13 rises along the inner wall of the inner ring cutter 9. After the washer stamping is completed, the outer ring cutter 3 and the inner ring cutter 9 reset. Under the elastic force of the telescopic spring 12 and the connecting spring 14, the sliding ring 11 and the sliding circular plate 13 reset. The waste material and the washer are respectively ejected from the outer ring cutter 3 and the inner ring cutter 9 through the sliding circular plate 13 and the sliding ring 11, avoiding the waste material and the washer being stuck in the outer ring cutter 3 and the inner ring cutter 9, eliminating the need for manual cleaning. The rubber sheet can be directly cut into gaskets without secondary processing, improving work efficiency. Moreover, the material can be pressed tightly during stamping, improving the stamping effect.

[0028] Refer to the attached drawings of the specification Figure 2 , the attached drawings of the specification Figure 4 and the attached drawings of the specification Figure 5 , a feed port 15 is provided on one side of the C-shaped bracket 2, a discharge port 16 is provided on the other side of the C-shaped bracket 2, a motor bracket 17 is installed on the C-shaped bracket 2, a driving motor 18 is installed on the motor bracket 17, a rotating rod 19 is rotatably connected in the feed port 15, one end of the rotating rod 19 is fixedly connected to the output end of the driving motor 18, and an anti-slip soft pad 20 is connected to the rotating rod 19.

[0029] Put the material plate into the feed port 15. The anti-slip soft pad 20 on the rotating rod 19 contacts the material plate. The driving motor 18 starts to work. The output end of the driving motor 18 drives the rotating rod 19 to rotate. The anti-slip soft pad 20 on the rotating rod 19 contacts the material plate. The driving motor 18 can intermittently drive the rotating rod 19 to rotate, enabling the material plate to move on the processing platform 1, conveying the material plate, and the anti-slip soft pad 20 plays an anti-slip role.

[0030] Refer to the attached drawings of the specification Figure 2 , the attached drawings of the specification Figure 4 and the attached drawings of the specification Figure 5A transverse chute 21 is provided on the processing platform 1, and two limit clamps 22 are provided in the feed port 15. The two limit clamps 22 are located below the rotating rod 19. A connecting slide bar 23 is installed at the bottom of the two limit clamps 22. The connecting slide bar 23 is slidably connected to the transverse chute 21. A plurality of universal balls 24 are provided on the two limit clamps 22. The bottom of the two connecting slide bars 23 is threadedly connected with a plum screw 25. A positioning plate 26 is provided on the screw of the plum screw 25.

[0031] When the rubber sheet is conveyed, the distance between the two limit clamps 22 is adjusted. When the limit clamps 22 move, the limit clamps 22 drive the connecting slide bar 23 to slide along the horizontal slide groove 21, and the rubber sheet is placed between the two limit clamps 22. Both sides of the rubber sheet contact the universal ball 24. After the limit clamps 22 are adjusted to the position, the operator tightens the inner plum screw 25 to make the positioning plate 26 fit with the bottom of the processing platform 1 to prevent the connecting slide bar 23 and the limit clamps 22 from moving. When the rotating roller 19 conveys the rubber sheet, the two limit clamps 22 are used to limit the rubber sheet to avoid position deviation when the rubber sheet moves, thereby improving the accuracy of the stamping position. The universal ball 24 improves the smoothness of the movement of the rubber sheet, avoids excessive friction between the rubber sheet and the limit clamps 22, and avoids bending and deformation of the rubber sheet. The two limit clamps 22 can all move, and the limit clamps 22 can drive the rubber sheet to move. Multiple horizontal stamping and cutting can be performed on the rubber sheet, thereby improving the utilization rate of the rubber sheet.
