Description

Technical Field

[0001] The present invention relates to the technical field of part stamping, and particularly to a continuous stamping device for automotive parts. Background Art

[0002] A stamping die, also known as a punching die, a hardware die, or a hardware stamping die, is a pressure processing method that uses a die fixed on a punching press or a press to apply a certain pressure to a metal or non-metal sheet, causing the material to separate or form, so as to obtain parts that meet certain dimensional requirements and have qualified appearance quality.

[0003] The patent with the authorization announcement number CN119456830B discloses a stamping die for steel structure production, including a machine table. A cooling mechanism is arranged on the top of the machine table. The cooling mechanism includes a slot opened on the top of the machine table. At least four through holes are evenly opened between the inner wall and the outer wall of the top of the slot. At least four fixing columns aligned with the through holes three are evenly fixed on the top of the machine table. A cavity is opened inside the fixing column.

[0004] However, the above-mentioned invention patent still has some deficiencies in actual use: 1. It can only cool the processed parts. Although the four nozzles are at different heights, each nozzle can only cool one place, and it is impossible to cool the side of the die and the contact surface between the die and the processed parts; 2. Only the elastic force of the spring one reset is used to drive the air flow to spray onto the surface of the remaining raw materials that have completed stamping. The impact force of the air flow is not large enough. Therefore, a continuous stamping device for automotive parts is proposed to solve the above-mentioned problems. Summary of the Invention

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] Refer to Figure 1 - Figure 11 , a continuous stamping device for automotive parts, including an upper box body 1, an operating table 3 and four support columns 2. The four support columns 2 are fixedly connected to the upper box body 1 and the operating table 3. A liquid storage tank 16 is fixedly connected to the inner wall of the operating table 3. A stamping cylinder 5 is fixedly connected inside the upper box body 1. An end of the stamping cylinder 5 is fixedly connected to a mounting plate 6. Four extrusion columns 7 are fixedly connected to the bottom of the mounting plate 6. A fixed cylinder 10 is arranged below each extrusion column 7. A sliding cylinder 8 is slidably connected to the outer wall of each fixed cylinder 10. Four arc-shaped brackets 4 arranged in a circumferential array are fixedly connected to the surface of the operating table 3. It further includes:

[0036] A multi-angle cooling mechanism 101, including a double nozzle seat 19, a direction-adjusting gear 22, an end limiting rod 17 and a double-sided rack 18. The multi-angle cooling mechanism 101 is installed on the arc-shaped bracket 4;

[0037] The combined upward movement mechanism 202 includes a clamping rod 26, a fixing plate 32 and a transmission shaft rod 33. The fixing plate 32 is fixedly connected to the sliding cylinder 8. The transmission shaft rod 33 is rotatably connected to the fixing plate 32. The transmission shaft rod 33 is fixedly connected to the clamping rod 26. The combined upward movement mechanism 202 is installed inside the sliding cylinder 8;

[0038] The switching mechanism 303 includes a large gear 29, a longitudinal rack 38, a second connecting rod 39 and a cutting plate 25. The large gear 29 meshes with the longitudinal rack 38. The longitudinal rack 38 is fixedly connected to the second connecting rod 39. The second connecting rod 39 is slidably connected to the sliding cylinder 8. The cutting plate 25 is fixedly connected to the second connecting rod 39. The switching mechanism 303 is installed inside the sliding cylinder 8;

[0039] And the pressurized air jetting mechanism 404 is installed on the outer wall of the sliding cylinder 8.

[0040] Wherein, buffer springs 9 are fixedly connected between the sliding cylinder 8 and the fixed cylinder 10. The double nozzle seat 19 is rotatably connected to the arc-shaped bracket 4. The steering gear 22 is fixedly connected to the end of the double nozzle seat 19. The end limiting rod 17 is fixedly connected to the arc-shaped bracket 4. The double-sided rack 18 is slidably connected to the end limiting rod 17. The inner wall of the double nozzle seat 19 communicates with an infusion hose 20 and an air transmission hose 21.

[0041] In this implementation scheme, the stamping cylinder 5 drives the mounting plate 6 to reciprocate to stamp the parts. When the stamping cylinder 5 moves downward, the extrusion column 7 abuts against the sliding cylinder 8, driving the sliding cylinder 8 to move downward along the fixed cylinder 10. It is set that an external force is required between the first limiting ring 28 and the inner sliding rod 23 to drive the two to slide relative to each other. When the extrusion column 7 drives the sliding cylinder 8 to move downward, the inner sliding rod 23 drives the first connecting rod 27 and the double-sided rack 18 to move downward. Since it is default that the double nozzle seat 19 faces downward initially, the combination of the ventilation hose 42, the liquid storage cavity 14 and the infusion hose 20 plays a role in liquid spraying and cooling, and the combination of the ventilation hose 36, the air bag 12 and the air transmission hose 21 plays a role in air jetting and drying.

[0042] Wherein, the combined upward movement mechanism 202 further includes a card slot 41, a stop rod 35, a second spring 34, a transverse rack 37 and a small gear 31. The card slot 41 is opened on the sliding cylinder 8. The stop rod 35 is fixedly connected to the second spring 34. The other end of the second spring 34 is fixedly connected to the sliding cylinder 8. The stop rod 35 is fixedly connected to the transverse rack 37. The transverse rack 37 is slidably connected to the sliding cylinder 8. The small gear 31 meshes with the transverse rack 37. The small gear 31 is fixedly connected to the clamping rod 26.

[0043] Among them, the switching mechanism 303 further includes a connecting shaft rod 30, a second ventilation hose 36, a third ventilation hose 42, and two one-way through holes 24. Both ends of the connecting shaft rod 30 are fixedly connected to the small gear 31 and the large gear 29. Both of the two one-way through holes 24 are fixedly connected to the sliding cylinder 8. One of the one-way through holes 24 is fixedly connected to the second ventilation hose 36, and the other one-way through hole 24 is fixedly connected to the third ventilation hose 42.

[0044] In this embodiment, as Figure 9 shown, the truncation plate 25 blocks the upper channel connected to the second ventilation hose 36 and opens the lower channel connected to the third ventilation hose 42. When the sliding cylinder 8 moves downward, it will squeeze the gas through the third ventilation hose 42 into the liquid storage cavity 14. The liquid storage cavity 14 will spray the internal coolant through one of the spray heads on the first infusion hose 20 and the double spray head seat 19. First, it sprays downward onto the processed part. Subsequently, the double-sided rack 18 moves downward along with the connecting rod one 27 and the sliding cylinder 8. The double-sided rack 18 meshes with the steering gear 22, and the steering gear 22 rotates the double spray head seat 19 obliquely upward to spray on the upper die. Finally, the other side of the double-sided rack 18 meshes with the steering gear 22, driving the double spray head seat 19 to spray horizontally on the side of the upper die, enabling the simultaneous cooling of the upper and lower dies and the processed part at one time.

[0045] Among them, a connecting rod one 27 is fixedly connected to the outer wall of the double-sided rack 18. An inner sliding rod 23 is fixedly connected to the outer wall of the connecting rod one 27. An inclined surface clamping block 40 is slidably connected to the inner wall of the inner sliding rod 23. A third spring 43 is fixedly connected between the inner sliding rod 23 and the inclined surface clamping block 40.

[0046] Among them, the other end of the third ventilation hose 42 is fixedly connected to a liquid storage cavity 14. The first infusion hose 20 is fixedly connected to the liquid storage cavity 14. A liquid supply pipe 15 is communicated with the outer wall of the liquid storage cavity 14. The liquid supply pipe 15 is communicated with a liquid storage tank 16. The liquid storage cavity 14 is fixedly connected to the operating table 3.

[0047] Among them, the pressurized air jetting mechanism 404 includes a first connecting rod 11, a push plate 13, and an air charging bag 12. The first connecting rod 11 is fixedly connected to the sliding cylinder 8. The push plate 13 is fixedly connected to the first connecting rod 11. The air charging bag 12 is fixedly connected to the inner wall of the operating table 3. The second ventilation hose 36 is communicated with the push plate 13. The first air delivery hose 21 is communicated with the air charging bag 12.

[0048] Among them, a one-way air inlet 44 is fixedly connected to the bottom outer wall of the fixed cylinder 10. A limit ring one 28 is fixedly connected to the top outer wall of the sliding cylinder 8.

[0049] In this embodiment, when the bilateral rack frame 18 moves along the end limit rod 17 to the lowest end of the end limit rod 17, at this time, since the sliding cylinder 8 is still moving downward, the inner sliding rod 23 and the first limiting ring 28 will slide. The inner sliding rod 23 moves upward relative to the first limiting ring 28. When the inclined surface clamping block 40 moves to the clamping groove 41, it extends into the clamping groove 41 under the elastic force of the third ventilation hose 42, squeezing the stop rod 35, so that the stop rod 35 drives the transverse rack 37 to move. The transverse rack 37 drives the pinion 31 to rotate. The tip of the clamping rod 26 is stuck in the annular groove outside the extrusion column 7. Subsequently, the connecting shaft rod 30 drives the large gear 29 to rotate synchronously with the pinion 31. The large gear 29 drives the second connecting rod 39 and the cutting-off plate 25 to move downward through the longitudinal rack 38. The cutting-off plate 25 opens the upper one-way through-hole 24 channel and closes the lower channel. At this time, the sliding cylinder 8 continues to move downward, so that the internal gas is input into the air bag 12 through the second ventilation hose 36 and temporarily stored in the air bag 12. Subsequently, since the clamping rod 26 is stuck on the outer wall of the extrusion column 7, when the stamping cylinder 5 retracts, the sliding cylinder 8 moves upward together with the extrusion column 7, rather than by the restoring force of the buffer spring 9. When the sliding cylinder 8 moves upward, it drives the push plate 13 to squeeze the gas in the air bag 12 through the first connecting rod 11, so that the gas jets on the outer wall of the upper die through the first gas transmission hose 21 first, then jets on the bottom of the upper die, and finally jets on the processed parts.

[0050] At the same time, when the sliding cylinder 8 moves upward, it replenishes the gas inside the fixed cylinder 10 through the one-way air inlet 44. When the bilateral rack frame 18 moves to the top of the end limit rod 17, the bilateral rack frame 18 stops moving. Therefore, at this time, the inner sliding rod 23 and the first limiting ring 28 slide relative to each other again. The inner sliding rod 23 moves downward relative to the first limiting ring 28, so that the third ventilation hose 42 disengages from the clamping groove 41 and everything returns to its original state.

[0051] The following makes a detailed explanation of the specific working principle and usage method of the present invention: When in use, the stamping cylinder 5 drives the mounting plate 6 to reciprocate to stamp the parts. When the stamping cylinder 5 moves downward, the extrusion column 7 abuts against the sliding cylinder 8, driving the sliding cylinder 8 to move downward along the fixed cylinder 10. It is set that an external force is required between the first limiting ring 28 and the inner sliding rod 23 to drive the two to slide relative to each other. When the extrusion column 7 drives the sliding cylinder 8 to move downward, the inner sliding rod 23 drives the first connecting rod 27 and the bilateral rack frame 18 to move downward. Since it is default that the double nozzle seat 19 faces downward initially, the combination of the third ventilation hose 42, the liquid storage cavity 14 and the first liquid transmission hose 20 plays a role in spraying liquid for cooling, and the combination of the second ventilation hose 36, the air bag 12 and the first gas transmission hose 21 plays a role in jetting air for drying.

[0052] As Figure 9As shown, the truncated plate 25 blocks the upper channel connected to the second ventilation hose 36 and opens the lower channel connected to the third ventilation hose 42. When the sliding cylinder 8 moves downward, it will squeeze the gas through the third ventilation hose 42 into the liquid storage cavity 14. The liquid storage cavity 14 will spray the internal coolant through one of the nozzles on the first infusion hose 20 and the double nozzle seat 19. First, it sprays downward onto the processed part. Subsequently, as the double-sided rack 18 moves downward along with the first connecting rod 27 and the sliding cylinder 8, the double-sided rack 18 meshes with the steering gear 22. The steering gear 22 rotates the double nozzle seat 19 obliquely upward to spray onto the upper die. Finally, the other side of the double-sided rack 18 meshes with the steering gear 22, driving the double nozzle seat 19 to spray horizontally onto the side of the upper die, enabling synchronous cooling of the upper and lower dies and the processed part at one time.

[0053] When the double-sided rack 18 moves along the end limiting rod 17 to the lowest end of the end limiting rod 17, at this time, since the sliding cylinder 8 is still moving downward, the inner sliding rod 23 and the first limiting ring 28 will slide. The inner sliding rod 23 moves upward relative to the first limiting ring 28. When the inclined surface block 40 moves to the clamping groove 41, it extends into the clamping groove 41 under the elastic force of the third ventilation hose 42 and squeezes the stop rod 35, causing the stop rod 35 to drive the transverse rack 37 to move. The transverse rack 37 drives the small gear 31 to rotate. The tip of the clamping rod 26 is stuck in the annular groove outside the extrusion column 7. Subsequently, the connecting shaft rod 30 drives the large gear 29 to rotate synchronously with the small gear 31. The large gear 29 drives the second connecting rod 39 and the truncated plate 25 to move downward through the longitudinal rack 38. The truncated plate 25 opens the upper one-way through hole 24 channel and closes the lower channel. At this time, the sliding cylinder 8 continues to move downward, enabling the internal gas to be input into the air bag 12 through the second ventilation hose 36 and temporarily stored by the air bag 12. Subsequently, since the clamping rod 26 is stuck on the outer wall of the extrusion column 7, when the stamping cylinder 5 retracts, the sliding cylinder 8 moves upward together with the extrusion column 7, rather than by the restoring force of the buffer spring 9. When the sliding cylinder 8 moves upward, it drives the push plate 13 to squeeze the gas in the air bag 12 through the first connecting rod 11, enabling the gas to spray on the outer wall of the upper die first through the first gas transmission hose 21, then on the bottom of the upper die, and finally on the processed part.

[0054] At the same time, when the sliding cylinder 8 moves upward, it replenishes the gas inside the fixed cylinder 10 through the one-way air inlet 44. When the double-sided rack 18 moves to the top of the end limiting rod 17, the double-sided rack 18 stops moving. Therefore, at this time, the inner sliding rod 23 and the first limiting ring 28 slide relative to each other again. The inner sliding rod 23 moves downward relative to the first limiting ring 28, causing the third ventilation hose 42 to disengage from the clamping groove 41 and everything returns to its original state.

[0055] Further explanation, unless otherwise clearly stipulated and limited, the above-mentioned fixed connection should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0056] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
