Description

Technical Field

[0001] The present invention belongs to the technical field of gasket processing, and particularly relates to a gasket processing device for a truck unloading pump. Background Art

[0002] As a key component to ensure the sealing performance of the truck unloading pump, the gasket of the truck unloading pump is generally installed at the shaft seal position of the pump or between the impeller and the cover of the centrifugal pump. It can effectively prevent media such as gas, liquid, and dust from leaking from the contact surface, thereby ensuring the stable and normal operation of the pump. In terms of raw material selection, natural rubber, nitrile rubber, neoprene, fluororubber, etc. are usually used. At the same time, multiple small holes are provided on the gasket of the truck unloading pump. These small holes serve as positioning holes and can play an important positioning role during the installation process of the gasket, ensuring a more accurate and efficient installation process.

[0003] In the prior art, the blanking process is a commonly used method in the processing of gaskets for truck unloading pumps. With its high efficiency and precision, this process can quickly and accurately separate the gasket shape that meets the design requirements from the raw material, especially showing significant advantages in large-scale production scenarios. However, after the blanking process finishes processing the raw material, the gasket of the truck unloading pump faces the problem of being inconvenient to remove from the mold.

[0006] Further, a round hole concentric with the ejector rod is provided on the stamping plate, and the round hole of the stamping plate coincides with the corresponding sliding hole.

[0007] Further, there are two long rotating rods between the base and the stamping plate. The two long rotating rods are jointly hinged with a first rotating pin. One end of a long rotating rod close to the base is rotatably arranged on the base, and one end of the other long rotating rod close to the base is rotatably arranged on the lower surface of the stamping plate when rotating. Both ends of the two long rotating rods far from the base are rotatably connected with short rotating rods. The two short rotating rods are jointly hinged with a second rotating pin. A side shifting plate is rotatably arranged on the first rotating pin. A long sliding groove 2101 for forming a sliding fit with the second rotating pin is arranged on the side shifting plate. A guide plate for receiving the gasket is arranged beside the side shifting plate.

[0008] Further, a feeding device is arranged beside the base on the side of the base. The feeding device includes a portal frame fixedly arranged above the base. A lower roller is rotatably arranged on the portal frame. The cylindrical surface of the lower roller is tangent to the upper surface of the ring punch. Sliders are slidably arranged on two side surfaces of the portal frame. An upper roller is rotatably arranged between the two sliders. Gears are arranged on the rotating shafts of the lower roller and the upper roller. The two gears are meshed with each other. The rotating shaft of the lower roller is connected with the inner ring of a one-way bearing. The outer ring of the one-way bearing is connected with one end of a lower rotating plate. The upper end of the lower rotating plate is hinged with the lower end of an upper rotating plate. The upper end of the upper rotating plate is hinged to the stamping plate.

[0009] Further, a connecting plate is jointly connected to the upper parts of the two sliders.

[0012] Further, a cutting knife is arranged on the female die, and a slideway is arranged on the base below the cutting knife.

[0013] The beneficial effects of the present invention compared with the prior art are as follows: (1) In the present invention, the processed gasket is stuck in the annular groove and rises with the female die. When the female die rises to the upper position, the ejector rod passes through the round hole of the stamping plate and enters the sliding hole. After the lower end of the ejector rod contacts the top end of the pressure rod, the ejector rod drives the pressure rod and the demoulding ring to move downward relative to the sliding hole, making the lower plane of the demoulding ring flush with the lower plane of the female die, and then the gasket can be pushed out of the annular groove; (2) In the present invention, the feeding plate is slidably arranged on the circular ring punch. When feeding, the upper plane of the feeding plate is flush with the upper plane of the circular ring punch, which is convenient for the raw material to be placed above the circular ring punch along the feeding plate; (3) When the stamping plate moves downward in the present invention, the first rotating pin drives the side shifting plate and the material guiding plate to move away from the base, making room for the descent of the stamping plate; when the stamping plate moves upward, the material guiding plate is translated under the female die, so the gasket falls from the annular groove onto the material guiding plate, and the gasket slides along the material guiding plate to the finished product area, avoiding the gasket directly falling onto the base; (4) During the upward movement of the stamping plate in the present invention, the upper rotating plate and the lower rotating plate rotate. The lower rotating plate drives the outer ring of the one-way bearing to rotate forward, and the outer ring of the one-way bearing drives its inner ring to rotate forward. Therefore, the lower roller rotates synchronously with the inner ring of the one-way bearing. Then, through the transmission of power by two gears, the upper roller rotates synchronously with the lower roller in the opposite direction, and the lower roller and the upper roller push the raw material onto the feeding plate and the circular ring punch, automatically preparing for the processing of the next gasket; (5) When the stamping plate drives the female die to descend in the present invention, the female die drives the cutting knife to descend synchronously. The cutting knife cuts the part that should be blanked into the gasket, and the cut waste enters the waste area along the slideway, which is convenient for subsequent processing. At the same time, it can also prevent the blanked area of the raw material from being too long, affecting the blanking of the remaining raw material into the gasket.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] As shown in Figures 1 to 13As shown in the figure, a processing device for the sealing gasket of a truck unloading pump includes a base 1, and is characterized in that: a base 2 is fixedly arranged on the base 1, a circular ring punch 3 is arranged in the middle of the base 2, four circular holes 301 are evenly arranged on the upper surface of the circular ring punch 3, a feeding plate 4 is slidably arranged on the circular ring punch 3, four sliding rods 5 are fixedly arranged below the feeding plate 4, the sliding rods 5 are slidably arranged on the base 2, a stop block 6 for blocking the upward sliding of the sliding rods 5 is arranged below the sliding rods 5, and a first spring 7 is sleeved outside the sliding rods 5, and the two ends of the first spring 7 are respectively connected with the base 2 and the feeding plate 4.

[0030] Specifically, in the original state, the first spring 7 provides elastic force, the upper surface of the stop block 6 contacts the base 2, so that the sliding rods 5 are in the upper position. At this time, the upper plane of the feeding plate 4 is flush with the upper plane of the circular ring punch 3, which is convenient for the raw material 40 to be placed above the circular ring punch 3 along the feeding plate 4.

[0031] Four guide rods 8 are vertically arranged above the base 1, the tops of the four guide rods 8 are jointly connected with a support platform 9, a hydraulic cylinder 10 is arranged on the upper surface of the support platform 9, the telescopic shaft of the hydraulic cylinder 10 passes through the support platform 9, and the end of the contraction shaft of the hydraulic cylinder 10 is connected with a stamping plate 11. A female die 12 is arranged below the stamping plate 11, an annular groove 1201 corresponding to the circular ring punch 3 is arranged at the center of the lower surface of the female die 12, a punch rod 1202 corresponding to the circular hole 301 is arranged in the annular groove 1201, and slide holes 1203 are arranged between every two adjacent punch rods 1202 on the female die 12.

[0032] A demoulding ring 13 is slidably arranged in the annular groove 1201, a punch rod hole 1301 which forms a sliding fit with the slide hole 1203 is arranged on the demoulding ring 13, four pressure rods 14 are arranged on the upper surface of the demoulding ring 13, the four pressure rods 14 are respectively slidably arranged in the four slide holes 1203, a second spring 15 is sleeved outside the pressure rods 14, the two ends of the second spring 15 are respectively connected with the female die 12 and the pressure rods 14, and a ejector rod 16 for driving the movement of the pressure rods 14 is arranged on the lower surface of the support platform 9.

[0033] Specifically, in the original state, the second spring 15 provides elastic force, so that the demoulding ring 13 and the pressure rods 14 are in the upper position, that is, the upper plane of the demoulding ring 13 contacts the plane of the annular groove 1201.

[0034] A circular hole concentric with the ejector rod 16 is arranged on the stamping plate 11, and the circular hole on the stamping plate 11 coincides with the corresponding slide hole 1203.

[0035] Specifically, place the raw material 40 on the feeding plate 4, start the hydraulic cylinder 10, the telescopic shaft of the hydraulic cylinder 10 drives the stamping plate 11 to move downward along the guide rod 8, the stamping plate 11 drives the female die 12 to move downward. After the female die 12 contacts the raw material 40, the female die 12 drives the feeding plate 4 to move downward along the circular punch 3, the first spring 7 is compressed, the circular punch 3 enters into the annular groove 1201, and the punching rod 1202 enters into the corresponding round hole 301, then the blanking of the raw material 40 can be completed to form the gasket 23. Start the hydraulic cylinder 10 in reverse, the telescopic shaft of the hydraulic cylinder 10 contracts, the stamping plate 11 and the female die 12 rise, the gasket 23 is stuck in the annular groove 1201 and rises with the female die 12. When the female die 12 rises to the upper position, the ejector rod 16 passes through the round hole of the stamping plate 11 and enters into the sliding hole 1203. After the lower end of the ejector rod 16 contacts the top end of the pressure rod 14, the ejector rod 16 drives the pressure rod 14 and the demolding ring 13 to move downward relative to the sliding hole 1203, so that the lower plane of the demolding ring 13 is flush with the lower plane of the female die 12, and then the gasket 23 can be pushed out from the annular groove 1201.

[0036] There are two long rotating rods 17 between the base 1 and the stamping plate 11. The two long rotating rods 17 are jointly hinged with a first rotating pin 18. One end of a long rotating rod 17 close to the base 2 is rotatably arranged on the base 1, and one end of the other long rotating rod 17 close to the base 2 is rotatably arranged on the lower surface of the stamping plate 11 when rotating. Both ends of the two long rotating rods 17 far from the base 2 are rotatably connected with short rotating rods 19. The two short rotating rods 19 are jointly hinged with a second rotating pin 20. A side shifting plate 21 is rotatably arranged on the first rotating pin 18. The side shifting plate 21 is provided with a long sliding groove 2101 which forms a sliding fit with the second rotating pin 20. A guide plate 22 for receiving the gasket 23 is arranged beside the side shifting plate 21.

[0037] Specifically, when the stamping plate 11 moves downward, both of the two long rotating rods 17 rotate, the first rotating pin 18 moves away from the base 2, and the first rotating pin 18 drives the side shifting plate 21 and the guide plate 22 to move away from the base 2 to make space for the descent of the stamping plate 11. During this process, the second rotating pin 20 slides in the long sliding groove (2101) to ensure that the side shifting plate 21 and the guide plate 22 do not rotate. When the stamping plate 11 moves upward, according to the reverse process of the above principle, the guide plate 22 moves toward the base 2, that is, the guide plate 22 translates to the lower part of the female die 12, so the gasket 23 falls from the annular groove 1201 onto the guide plate 22, and the gasket 23 slides along the guide plate 22 to the finished product area, avoiding the gasket 23 directly falling onto the base 1.

[0038] On the base 1, beside the base 2, there is a feeding device. The feeding device includes a gantry frame 24 fixedly arranged above the base 1. A lower roller 25 is rotatably arranged on the gantry frame 24. The cylindrical surface of the lower roller 25 is tangent to the upper surface of the ring punch 3. Sliders 26 are slidably arranged on the two side surfaces of the gantry frame 24. An upper roller 27 is rotatably arranged between the two sliders 26. Gears 28 are arranged on the rotating shafts of the lower roller 25 and the upper roller 27. The two gears 28 mesh with each other. The rotating shaft of the lower roller 25 is connected to the inner ring of a one-way bearing 29. The outer ring of the one-way bearing 29 is connected to one end of a lower rotating plate 30. The upper end of the lower rotating plate 30 is hinged to the lower end of an upper rotating plate 31. The upper end of the upper rotating plate 31 is hinged to the stamping plate 11.

[0039] The upper parts of the two sliders 26 are jointly connected with a connecting plate 32. Two screws 33 are screwed on the upper flat plate of the gantry frame 24 and above the connecting plate 32. The lower ends of the screws 33 extend into the connecting plate 32. A third spring 34 is sleeved outside the screws 33. The two ends of the third spring 34 are respectively connected to the connecting plate 32 and the slider 26.

[0040] The upper part of the connecting plate 32 is rotatably connected to the lower end of a connecting rod 35. The connecting rod 35 passes through the upper flat plate of the gantry frame 24. The upper end of the connecting rod 35 is rotatably connected to one end of a lever plate 36. The middle part of the lever plate 36 is rotatably arranged on the upper flat plate of the gantry frame 24.

[0041] Specifically, by adjusting the screwing depth of the two screws 33 in the upper flat plate of the gantry frame 24, the compression amount of the third spring 34 can be adjusted, thereby adjusting the downward pressure of the connecting plate 32 and the slider 26. Therefore, the pressure between the upper roller 27 and the lower roller 25 can be adjusted to adapt to raw materials 40 of different thicknesses.

[0042] Rotate the lever plate 36 to make the end of the lever plate 36 close to the connecting rod 35 rise. Then, transmit the power through the connecting rod 35 to make the connecting plate 32 and the slider 26 rise, and the upper roller 27 and the lower roller 25 separate. Place the raw material 40 into the upper roller 27. Release the lever plate 36, and the third spring 34 provides elastic force to clamp the raw material 40 by the upper roller 27 and the lower roller 25.

[0043] When the stamping plate 11 rises, the upper rotating plate 31 and the lower rotating plate 30 rotate. The lower rotating plate 30 drives the outer ring of the one-way bearing 29 to rotate forward. The outer ring of the one-way bearing 29 drives its inner ring to rotate forward. Therefore, the lower roller 25 rotates synchronously with the inner ring of the one-way bearing 29. Then, transmit the power through the two gears 28 to make the upper roller 27 rotate synchronously with the lower roller 25 in the opposite direction. The lower roller 25 and the upper roller 27 push the raw material 40 onto the feeding plate 4 and the ring punch 3 to prepare for processing the gasket 23. When the stamping plate 11 descends, the outer ring of the one-way bearing 29 rotates reversely, and the inner ring of the short rotating rod 19 no longer rotates, that is, the lower roller 25 and the upper roller 27 no longer rotate, and the raw material 40 stops moving.

[0044] On the side plate of the base 1, there is a side base plate 37. A disc 38 is rotatably arranged at the middle part of the side base plate 37. A plurality of rolling rods 39 are rotatably arranged around the disc 38 on the side base plate 37. The coil of the raw material 40 is placed at the center of the plurality of rolling rods 39. Two rolling rods 39 are jointly and detachably connected with a baffle 41. Optionally, threaded holes are provided on the outer part of the rolling rods 39. After the baffle 41 is sleeved on the rolling rods 39, a nut is screwed into the threaded holes of the rolling rods 39 to complete the installation of the baffle 41.

[0045] Specifically, the coil of the raw material 40 is placed among the plurality of rolling rods 39, and then the baffle 41 is installed on the rolling rods 39 to prevent the raw material 40 from falling. The head of the coil of the raw material 40 is pulled out from the upper two rolling rods 39 and placed between the lower roller 25 and the upper roller 27. When the raw material 40 is placed on the circular ring punch 3 and the feeding plate 4, the coil of the raw material 40 rotates among the plurality of rolling rods 39.

[0046] A cutting knife 42 is provided on the female die 12. A slideway 43 is provided on the base 1 and below the cutting knife 42. When the stamping plate 11 drives the female die 12 to descend, the female die 12 drives the cutting knife 42 to descend synchronously. The cutting knife 42 cuts the part that should be blanked out the gasket 23. The cut waste material enters the waste area along the slideway 43 for subsequent treatment, and at the same time, it can also prevent the blanked area of the raw material 40 from being too long, which affects the blanking of the remaining raw material 40 into the gasket 23.

[0047] Working principle: In the preparation stage, the coil of the raw material 40 is placed among the plurality of rolling rods 39, and then the baffle 41 is installed on the rolling rods 39 to prevent the raw material 40 from falling. The head of the coil of the raw material 40 is pulled out from the upper two rolling rods 39. The lever plate 36 is rotated so that the end of the lever plate 36 close to the connecting rod 35 rises, and then power is transmitted through the connecting rod 35 to make the connecting plate 32 and the slider 26 rise, and the upper roller 27 and the lower roller 25 are separated. The head of the raw material 40 is placed between the upper roller 27 and the lower roller 25, and the head of the raw material 40 is placed above the circular ring punch 3. The lever plate 36 is released, and the spring three 34 provides elastic force to make the upper roller 27 and the lower roller 25 clamp the raw material 40.

[0048] In the original state, the spring one 7 provides elastic force, the upper surface of the stop block 6 contacts the base 2, so that the slide rod 5 is in the upper position. At this time, the upper plane of the feeding plate 4 is flush with the upper plane of the circular ring punch 3, which is convenient for the raw material 40 to be placed above the circular ring punch 3 along the feeding plate 4; at the same time, the spring two 15 provides elastic force to make the demolding ring 13 and the pressing rod 14 in the upper position, that is, the upper plane of the demolding ring 13 contacts the plane of the annular groove 1201.

[0049] Start the hydraulic cylinder 10. The telescopic shaft of the hydraulic cylinder 10 drives the stamping plate 11 to move downward along the guide rod 8. During this process, both long rotating rods 17 rotate, the first rotating pin 18 moves away from the base 2, and the first rotating pin 18 drives the side shift plate 21 and the material guiding plate 22 to move away from the base 2, creating space for the downward movement of the stamping plate 11. When the stamping plate 11 drives the female die 12 to move downward and contact the raw material 40, the female die 12 drives the feeding plate 4 to move downward along the circular ring punch 3, the first spring 7 compresses, the circular ring punch 3 enters the annular groove 1201, and the punching rod 1202 enters the corresponding round hole 301, then the blanking of the raw material 40 can be completed to form the gasket 23.

[0050] Start the hydraulic cylinder 10 in the reverse direction. The telescopic shaft of the hydraulic cylinder 10 contracts, the stamping plate 11 and the female die 12 rise, and the gasket 23 is stuck in the annular groove 1201 and rises with the female die 12. During this process, the material guiding plate 22 moves toward the base 2, that is, the material guiding plate 22 translates to the lower part of the female die 12. When the female die 12 rises to the upper position, the ejector rod 16 passes through the round hole of the stamping plate 11 and enters the sliding hole 1203. After the lower end of the ejector rod 16 contacts the top of the pressure rod 14, the ejector rod 16 drives the pressure rod 14 and the demolding ring 13 to move downward relative to the sliding hole 1203, making the lower plane of the demolding ring 13 flush with the lower plane of the female die 12, then the gasket 23 can be pushed out from the annular groove 1201 onto the material guiding plate 22, and the gasket 23 slides along the material guiding plate 22 into the finished product area, avoiding the gasket 23 directly falling onto the base 1.

[0051] Meanwhile, during the rising process of the stamping plate 11, the upper rotating plate 31 and the lower rotating plate 30 rotate. The lower rotating plate 30 drives the outer ring of the one-way bearing 29 to rotate forward, and the outer ring of the one-way bearing 29 drives its inner ring to rotate forward. Therefore, the lower roller 25 rotates synchronously with the inner ring of the one-way bearing 29. Then, through the transmission of power by two gears 28, the upper roller 27 rotates synchronously with the lower roller 25 in the opposite direction. The lower roller 25 and the upper roller 27 push the raw material 40 onto the feeding plate 4 and the circular ring punch 3, automatically preparing for the processing of the next gasket 23. The part where the gasket 23 has been blanked moves to the outside of the circular ring punch 3. When the stamping plate 11 and the female die 12 descend next time, the cutter 42 cuts the part where the gasket 23 should be blanked. The cut waste enters the waste area along the slideway 43, which is convenient for subsequent processing, and at the same time can also prevent the blanked area of the raw material 40 from being too long, affecting the blanking of the remaining raw material 40 into the gasket 23.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
