It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figures 1 to 13 As shown, a truck unloading pump sealing gasket processing equipment includes a base 1, characterized in that: a base 2 is fixedly provided on the base 1, a circular ring punch 3 is provided in the middle of the base 2, four circular holes 301 are evenly provided on the upper surface of the circular ring punch 3, a feeding plate 4 is slidably provided on the circular ring punch 3, four sliding rods 5 are fixedly provided below the feeding plate 4, the sliding rod 5 is slidably provided on the base 2, a stopper 6 for preventing the sliding rod 5 from sliding upward is provided below the sliding rod 5, a spring 7 is provided on the outer sleeve of the sliding rod 5, and the two ends of the spring 7 are respectively connected to the base 2 and the feeding plate 4.

[0018] Specifically, in the original state, spring 1 7 provides elastic force, the upper surface of the stopper 6 contacts the base 2, so that the slide rod 5 is in the upper position. At this time, the upper plane of the feed plate 4 is flush with the upper plane of the circular ring punch 3, which facilitates the raw material 40 to be placed along the feed plate 4 to the top of the circular ring punch 3.

[0019] Four guide rods 8 are vertically arranged above the base 1, and the tops of the four guide rods 8 are commonly connected to a support platform 9. A hydraulic cylinder 10 is arranged on the upper surface of the support platform 9, and the telescopic axis of the hydraulic cylinder 10 passes through the support platform 9, and the end of the contraction axis of the hydraulic cylinder 10 is connected to a stamping plate 11, and a 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 die 12, and a punch rod 1202 corresponding to the circular hole 301 is arranged in the annular groove 1201, and a sliding hole 1203 is arranged between two adjacent punch rods 1202 on the die 12.

[0020] A demolding ring 13 is slidably provided in the annular groove 1201, and a punch hole 1301 is provided on the demolding ring 13 to form a sliding fit with the sliding hole 1203. Four pressure rods 14 are provided on the upper surface of the demolding ring 13. The four pressure rods 14 are respectively slidably provided in the four sliding holes 1203. A spring 15 is provided on the outer sleeve of the pressure rod 14. The two ends of the spring 15 are respectively connected to a concave mold 12 and the pressure rod 14. A push rod 16 for driving the pressure rod 14 to move is provided on the lower surface of the support platform 9.

[0021] Specifically, in the original state, the spring 2 15 provides elastic force to keep the demoulding ring 13 and the pressure rod 14 in the upper position, that is, the upper plane of the demoulding ring 13 contacts the plane of the annular groove 1201 .

[0022] The stamping plate 11 is provided with a circular hole which is concentric with the ejector rod 16 , and the circular hole of the stamping plate 11 coincides with the corresponding sliding hole 1203 .

[0023] Specifically, the raw material 40 is placed on the feeding plate 4, and the hydraulic cylinder 10 is started. The telescopic shaft of the hydraulic cylinder 10 drives the stamping plate 11 to move downward along the guide rod 8, and the stamping plate 11 moves downward with the die 12. After the die 12 contacts the raw material 40, the die 12 drives the feeding plate 4 to move downward along the annular punch 3, the spring 7 is compressed, the annular punch 3 enters the annular groove 1201, and the punch rod 1202 enters the corresponding circular hole 301, thereby completing the blanking of the raw material 40 to form a sealing gasket 23. The hydraulic cylinder 10 is started in reverse, the telescopic shaft of the hydraulic cylinder 10 contracts, the stamping plate 11 and the die 12 rise, and the sealing gasket 23 is stuck in the annular groove 1201 and rises with the die 12. When the die 12 rises to the upper position, the push rod 16 passes through the circular hole of the stamping plate 11 and enters the sliding hole 1203. After the lower end of the push rod 16 contacts the top of the pressure rod 14, the push 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 die 12, and the sealing gasket 23 can be pushed out from the annular groove 1201.

[0024] There are two long rotating rods 17 between the base 1 and the stamping plate 11, and the two long rotating rods 17 are hinged with a rotating pin 18. One end of the long rotating rod 17 close to the base 2 is rotatably arranged on the base 1, and the other end of the long rotating rod 17 close to the base 2 is rotatably arranged on the lower surface of the stamping plate 11. The ends of the two long rotating rods 17 away from the base 2 are rotatably connected with short rotating rods 19, and the two short rotating rods 19 are hinged with a rotating pin 20. A side shift plate 21 is rotatably provided on the rotating pin 18, and a long slide groove 2101 is provided on the side shift plate 21 to form a sliding fit with the rotating pin 20. A material guide plate 22 for receiving a sealing gasket 23 is provided on the side of the side shift plate 21.

[0025] Specifically, when the punching plate 11 moves downward, the two long rotating rods 17 rotate, the rotating pin 18 moves away from the base 2, and the rotating pin 18 moves away from the base 2 with the side shift plate 21 and the guide plate 22 to make room for the descent of the punching plate 11. During this process, the rotating pin 20 slides in the long slide groove (2101) to ensure that the side shift plate 21 and the guide plate 22 do not rotate. When the punching plate 11 moves upward, the process is reversed to the above principle, and the guide plate 22 moves toward the base 2, that is, the guide plate 22 translates to the bottom of the die 12, so the sealing gasket 23 falls from the annular groove 1201 onto the guide plate 22, and the sealing gasket 23 slides along the guide plate 22 to the finished product area, preventing the sealing gasket 23 from falling directly onto the base 1.

[0026] A feeding device is provided on the base 1 at the side of the base 2, and the feeding device includes a portal frame 24 fixedly arranged above the base 1, a lower roller 25 is rotatably provided on the portal frame 24, and the cylindrical surface of the lower roller 25 is tangent to the upper surface of the circular ring punch 3, sliders 26 are slidably provided on the two side surfaces of the portal frame 24, and an upper roller 27 is rotatably provided between the two sliders 26, and gears 28 are provided on the rotating shafts of the lower roller 25 and the upper roller 27, and the two gears 28 are meshed with each other, the rotating shaft of the lower roller 25 is connected to the inner ring of the one-way bearing 29, the outer ring of the one-way bearing 29 is connected to one end of the lower rotating plate 30, the upper end of the lower rotating plate 30 is hinged to the lower end of the upper rotating plate 31, and the upper end of the upper rotating plate 31 is hinged to the stamping plate 11.

[0027] The upper parts of the two sliders 26 are commonly connected with a connecting plate 32. The upper flat plate of the door frame 24 is located above the connecting plate 32 and is spirally connected with two screws 33. The lower ends of the screws 33 extend into the connecting plate 32. A spring 34 is sleeved on the outside of the screws 33. The two ends of the spring 34 are respectively connected to the connecting plate 32 and the slider 26.

[0028] The upper part of the connecting plate 32 is rotatably connected to the lower end of the connecting rod 35, the connecting rod 35 passes through the upper flat plate of the portal frame 24, the upper end of the connecting rod 35 is rotatably connected to one end of the lever plate 36, and the middle part of the lever plate 36 is rotatably arranged on the upper flat plate of the portal frame 24.

[0029] Specifically, by adjusting the depth of the two screws 33 screwed into the upper plate of the door frame 24, the compression amount of the spring three 34 can be adjusted, thereby adjusting the downward pressure of the connecting plate 32 and the slider 26, so that the pressure between the upper roller 27 and the lower roller 25 can be adjusted to adapt to raw materials 40 of different thicknesses.

[0030] The lever plate 36 is rotated to make one end of the lever plate 36 close to the connecting rod 35 rise, and then the power is transmitted through the connecting rod 35 to make the connecting plate 32 and the slider 26 rise, the upper roller 27 and the lower roller 25 separate, and the raw material 40 is placed into the upper roller 27. The lever plate 36 is released, and the spring three 34 provides elastic force so that the upper roller 27 and the lower roller 25 clamp the raw material 40.

[0031] When the punching plate 11 rises, the upper rotating plate 31 and the lower rotating plate 30 rotate, and 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, so the lower roller 25 rotates synchronously with the inner ring of the one-way bearing 29, and then transmits power through the two gears 28, so that the upper roller 27 rotates synchronously with the lower roller 25 in the opposite direction, and the lower roller 25 and the upper roller 27 push the raw material 40 onto the feeding plate 4 and the circular punch 3 to prepare for processing the sealing gasket 23. When the punching plate 11 descends, the outer ring of the one-way bearing 29 rotates in the opposite direction, 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.

[0032] A side base plate 37 is provided on the side plate of the base 1, a disc 38 is rotatably provided in the middle part of the side base plate 37, a plurality of rollers 39 are provided on the side base plate 37 and rotate evenly around the disc 38, a roll of raw material 40 is put into the center of the plurality of rollers 39, two rollers 39 are connected together with a baffle 41 in a detachable manner, optionally, a threaded hole is provided on the outside of the roller 39, after the baffle 41 is inserted into the roller 39, a nut is screwed into the threaded hole of the roller 39, and the installation of the baffle 41 is completed.

[0033] Specifically, the roll of raw material 40 is placed into a plurality of rollers 39, and then a baffle 41 is installed on the rollers 39 to prevent the raw material 40 from falling. The head of the roll of raw material 40 is pulled out from the upper two rollers 39 and placed between the lower roller 25 and the upper roller 27. When the raw material 40 is placed onto the annular punch 3 and the feed plate 4, the roll of raw material 40 rotates in the plurality of rollers 39.

[0034] A cutter 42 is provided on the die 12, and a slide 43 is provided on the base 1 and below the cutter 42. When the stamping plate 11 descends with the die 12, the die 12 descends synchronously with the cutter 42. The cutter 42 cuts the portion where the sealing gasket 23 should be punched out, and the waste after cutting enters the waste area along the slide 43 for subsequent processing. At the same time, it can also avoid the punched area of ​​the raw material 40 being too long, which affects the punching of the sealing gasket 23 from the remaining raw material 40.

[0035] Working principle: In the preparation stage, the roll of the raw material 40 is placed into the multiple rollers 39, and then the baffle 41 is installed on the rollers 39 to prevent the raw material 40 from falling, and the head of the roll of the raw material 40 is pulled out from the upper two rollers 39. The lever plate 36 is rotated to make the end of the lever plate 36 close to the connecting rod 35 rise, and then the 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, and the head of the raw material 40 is placed into the upper roller 27 and the lower roller 25, and the head of the raw material 40 is placed above the circular punch 3. The lever plate 36 is released, and the spring 34 provides elastic force, so that the upper roller 27 and the lower roller 25 clamp the raw material 40.

[0036] In the original state, spring 1 7 provides elastic force, and the upper surface of the stopper 6 contacts the base 2, so that the slide rod 5 is in the upper position. At this time, the upper plane of the feed 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 along the feed plate 4 to the top of the circular ring punch 3; at the same time, spring 2 15 provides elastic force, so that the demolding ring 13 and the pressure rod 14 are in the upper position, even if the upper plane of the demolding ring 13 contacts the plane of the annular groove 1201.

[0037] Start the hydraulic cylinder 10, and the telescopic shaft of the hydraulic cylinder 10 drives the punching plate 11 to move downward along the guide rod 8. During this process, the two long rotating rods 17 rotate, and the rotating pin 18 moves away from the base 2. The rotating pin 18 moves away from the base 2 with the side shift plate 21 and the guide plate 22 to make room for the descent of the punching plate 11. When the punching plate 11 moves downward with the die 12 and contacts the raw material 40, the die 12 drives the feed plate 4 to move downward along the annular punch 3, the spring 7 is compressed, the annular punch 3 enters the annular groove 1201, and the punch rod 1202 enters the corresponding circular hole 301, so that the blanking of the raw material 40 can be completed to form the sealing gasket 23.

[0038] The hydraulic cylinder 10 is started in the reverse direction, the telescopic shaft of the hydraulic cylinder 10 is contracted, the stamping plate 11 and the die 12 are raised, and the sealing gasket 23 is stuck in the annular groove 1201 and rises with the die 12. In this process, the guide plate 22 moves in the direction close to the base 2, that is, the guide plate 22 is translated to the bottom of the die 12. When the die 12 rises to the upper position, the push rod 16 passes through the circular hole of the stamping plate 11 and enters the sliding hole 1203. After the lower end of the push rod 16 contacts the top of the pressure rod 14, the push rod 16 drives the pressure rod 14 and the demoulding ring 13 to move downward relative to the sliding hole 1203, so that the lower plane of the demoulding ring 13 is flush with the lower plane of the die 12, and the sealing gasket 23 can be pushed out from the annular groove 1201 to the guide plate 22, and the sealing gasket 23 slides along the guide plate 22 to the finished product area, preventing the sealing gasket 23 from falling directly onto the base 1.

[0039] At the same time, during the rising process of the punching 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, so the lower roller 25 rotates synchronously with the inner ring of the one-way bearing 29, and then transmits power through the two gears 28, so that the upper roller 27 rotates synchronously with the lower roller 25 in the opposite direction, and 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 sealing gasket 23. The part of the sealing gasket 23 that has been punched out moves to the outside of the circular ring punch 3. When the punching plate 11 and the die 12 are lowered next time, the cutter 42 cuts the part of the sealing gasket 23 that should be punched out, and the waste after cutting enters the waste area along the slide 43 for subsequent processing, and at the same time, it can also avoid that the punched area of ​​the raw material 40 is too long, which affects the punching out of the remaining raw material 40.

[0040] 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 included in the protection scope of the present invention.
