Furthermore, the pressure ring quickly springs back to its original position, causing deformation of the formed body panel and affecting product quality.

Description

Technical Field

[0001] This invention relates to the field of automotive body panel processing technology, and in particular to a drawing die pressure driving device for automotive body panels. Background Technology

[0002] With fierce market competition and changing customer demands for automobiles, the precision requirements for molds are increasing, mold manufacturing processes are maturing, and the requirements for mold surface lines are becoming more complex. Therefore, mold manufacturing technology needs to continuously improve mold quality in line with market demands. Drawing dies are the most critical process in automobile production, directly affecting the surface quality of stamped parts and the quality of sheet metal assembly.

[0003] In existing automotive body panel drawing die pressure drive devices, after the upper and lower dies complete the stamping of the material plate, the formed body panel will be adsorbed onto the lower die due to the negative pressure. Usually, the formed body panel is unloaded manually, which is cumbersome and laborious. Moreover, after the upper die pushes the pressure ring downward for stamping, the pressure ring is usually subjected to the elastic force of the support spring mounted on the guide rod, which makes it quickly spring back to its original position. This causes the pressure ring to deform the formed body panel by pressing it upward, affecting product quality. Summary of the Invention

[0004] In view of this, the present invention provides a drawing die pressure driving device for automotive body panels, to solve the problem that in existing drawing die pressure driving devices for automotive body panels, after the upper and lower dies have completed the stamping of the material plate, the formed body panels are usually unloaded manually, which is cumbersome and laborious. Moreover, the pressure ring quickly springs back to its original position, causing the body panels formed by the upward extrusion to deform, which affects the product quality.

[0005] This invention provides a drawing die pressure driving device for automotive body panels, specifically comprising: a base plate, the top of which is provided with a base; a pressure ring provided within the base; a lower die provided within the pressure ring, the lower die being located at the center of the top of the base plate; two lifting members provided on the pressure ring, the two lifting members being symmetrically distributed; a top mounting bracket and a bottom mounting bracket provided within the left and right vertical plates of the pressure ring, the top mounting bracket being located below the lifting members; first drive motors provided on the left and right sides of the pressure ring, the two first drive motors being symmetrically distributed; and an upper die provided above the lower die.

[0006] Furthermore, the base plate is provided with four guide rods arranged in a rectangular array, and a support spring is fitted on each guide rod. The guide rods slide through the pressure ring, and the support springs support the bottom of the pressure ring. A fixed plate is provided at the top center of the base plate, and two first guide rails are provided on the fixed plate, which are symmetrically distributed. Two sets of scissor bars are provided on the fixed plate, and a support plate is provided on each scissor bar. One end of the bottom of the scissor bar is connected to the fixed plate by a rotating bracket, and the other end of the bottom of the scissor bar is slidably connected to the first guide rail through a sliding sleeve.

[0007] Furthermore, the pressure ring is provided with fixed covers on the left and right sides, and the first drive motor is located inside the fixed covers. The left and right vertical plates of the pressure ring are provided with mounting cavities, and the top mounting bracket and the bottom mounting bracket are located in the mounting cavities. The bottom of the pressure ring is provided with a through hole, and the through hole communicates with the mounting cavity.

[0008] Furthermore, a through cavity is provided at the middle position of the bottom of the lower mold, and a second drive motor is provided in the through cavity. The scissor bar and the support plate are located on the left and right sides of the lower mold, and the support plate is located below the pressure ring.

[0009] Furthermore, a support block is provided at the middle position of the bottom of the lifting member, and one side edge of the bottom of the support block is chamfered. Tension springs are provided on both sides of the bottom of the lifting member, and the two tension springs are distributed symmetrically.

[0010] Furthermore, a sliding block is slidably installed in the middle groove of the top mounting bracket, and one side edge of the top of the sliding block is chamfered, and the chamfer of the sliding block matches the chamfer of the support block. Support seats are provided on both sides of the top of the top mounting bracket, and the two ends of the tension spring are respectively connected to the lifting member and the support seat. A first toothed plate is provided at the bottom of the sliding block.

[0011] Furthermore, a second toothed plate is slidably installed in the middle groove of the bottom mounting bracket, and the second toothed plate is located opposite to the first toothed plate, and a limiting block is provided at one end of the second toothed plate.

[0012] Furthermore, the first drive motor is provided with a rotating shaft, and the rotating shaft is rotatably connected to the pressure ring through a bearing. The rotating shaft is provided with a gear, and the gear is located in the mounting cavity, and the gear meshes with the second gear plate and the first gear plate.

[0013] Furthermore, the top of the support plate is provided with a limiting clip, which corresponds to the position of the through hole. The limiting clip has an L-shaped structure. When the support plate and the pressure ring are connected, the limiting clip passes through the through hole and is located in the sliding groove of the bottom mounting bracket. The limiting clip is engaged with the limiting clip. The bottom of the support plate is provided with a second guide rail. One end of the scissor bar's top rotating bracket is connected to the support plate, and the other end of the scissor bar's top rotating bracket is slidably connected to the second guide rail through a sliding sleeve.

Both ends of the connecting rod are connected to the sleeves of the rotating frame at the bottom of the scissor lift.

[0015] Beneficial effects

[0016] 1. After the upper and lower molds have completed the stamping of the material plate, the first drive motor provides power and uses gear meshing to drive the first toothed plate to slide along the slide groove of the top mounting bracket. The sliding block pushes the support block to make the lifting part slide upward. The lifting part can lift the formed cover part upward, so that it can quickly detach from the lower mold, which saves the trouble of manual detachment.

[0017] 2. When the upper mold pushes the pressure ring downwards, the support plate and the pressure ring are connected. The limiting clip passes through the through hole and is located in the slide groove of the bottom mounting bracket. The gear meshing drives the second toothed plate to slide along the slide groove of the bottom mounting bracket, so that the limiting block and the limiting clip are engaged. This prevents the pressure ring from rebounding upwards and resetting due to the elastic force of the support spring, and avoids deformation of the cover formed by the upward pressing of the pressure ring, thereby effectively ensuring the quality of the product.

[0018] 3. The present invention is powered by a second drive motor. By adjusting the screw rotation, the threaded sleeve drives the connecting rod to slide, which in turn drives the sliding sleeve of the rotating frame at one end of the scissor lift to slide along the first guide rail and the second guide rail. The scissor lift can drive the support plate to slide upward, thereby simultaneously driving the pressure ring to rise steadily and slowly. This structure is simple and easy to use and operate.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0033] Example: Please refer to Figures 1 to 8 As shown:

[0034] This invention provides a drawing die pressure driving device for automotive body panels, including a base plate 1, a base 2 on the top of the base plate 1; a pressing ring 3 inside the base 2; a lower die 4 inside the pressing ring 3, and the lower die 4 is located at the middle of the top of the base plate 1; two lifting members 5 are provided on the pressing ring 3, and the two lifting members 5 are distributed symmetrically; a top mounting bracket 6 and a bottom mounting bracket 7 are provided in the left and right vertical plates of the pressing ring 3, and the top mounting bracket 6 is located below the lifting members 5; a first drive motor 8 is provided on the left and right sides of the pressing ring 3, and the two first drive motors 8 are distributed symmetrically; an upper die 12 is provided above the lower die 4.

[0035] The base plate 1 has four guide rods 101 arranged in a rectangular array. A support spring 102 is fitted on each guide rod 101. The guide rods 101 slide through the pressure ring 3, and the support spring 102 is supported at the bottom of the pressure ring 3.

[0036] The pressing ring 3 has two fixing covers 301 on the left and right sides, and the first drive motor 8 is set in the fixing cover 301. The pressing ring 3 has mounting cavities 302 on the left and right vertical plates, and the top mounting bracket 6 and the bottom mounting bracket 7 are located in the mounting cavity 302. The pressing ring 3 has a through hole 303 at the bottom, and the through hole 303 communicates with the mounting cavity 302.

[0037] A support block 501 is provided at the middle of the bottom of the lifting component 5, and one side of the bottom edge of the support block 501 is chamfered. Tension springs 502 are provided on both sides of the bottom of the lifting component 5, and the two tension springs 502 are distributed symmetrically.

[0038] A sliding block 601 is slidably installed in the middle groove of the top mounting bracket 6, and the top edge of the sliding block 601 is chamfered, and the chamfer of the sliding block 601 matches the chamfer of the support block 501. Support seats 602 are provided on both sides of the top of the top mounting bracket 6, and the two ends of the tension spring 502 are respectively connected to the lifting member 5 and the support seat 602. A first toothed plate 603 is provided at the bottom of the sliding block 601.

[0039] The first drive motor 8 is equipped with a rotating shaft 801, which is rotatably connected to the pressure ring 3 through a bearing. The rotating shaft 801 is equipped with a gear 802, which is located in the mounting cavity 302. The gear 802 is meshed with the second toothed plate 701 and the first toothed plate 603. After the upper mold 12 and the lower mold 4 complete the stamping of the material plate, the first drive motor 8 provides power and the gear 802 meshes to drive the first toothed plate 603 to slide along the slide groove of the top mounting bracket 6. The sliding block 601 pushes the support block 501 to make the lifting member 5 slide upward. The lifting member 5 can lift the formed cover part upward so that it can quickly detach from the lower mold 4, which saves the trouble of manual detachment.

[0040] The lower mold 4 has a cavity 401 at the bottom center, and a second drive motor 11 is provided in the cavity 401. The scissor bar 9 and the support plate 10 are located on the left and right sides of the lower mold 4, and the support plate 10 is located below the pressure ring 3.

[0041] A second toothed plate 701 is slidably installed in the middle groove of the bottom mounting bracket 7, and the second toothed plate 701 is located opposite to the first toothed plate 603, and a limiting block 702 is provided at one end of the second toothed plate 701.

[0042] The support plate 10 is provided with a limiting clip 1001 at the top, and the limiting clip 1001 corresponds to the position of the through hole 303. The limiting clip 1001 has an L-shaped structure. When the upper mold 12 pushes the pressure ring 3 downward, the support plate 10 and the pressure ring 3 are connected. The limiting clip 1001 passes through the through hole 303 and is located in the slide groove of the bottom mounting bracket 7. The gear 802 is used to drive the second toothed plate 701 to slide along the slide groove of the bottom mounting bracket 7, so that the limiting clip 702 and the limiting clip 1001 are engaged. This can prevent the pressure ring 3 from rebounding upward and resetting rapidly due to the elastic force of the support spring 102, and avoid deformation of the cover formed by the upward pressing of the pressure ring 3, thereby effectively ensuring the quality of the product.

[0043] The base plate 1 has a fixed plate 103 at the top center, and two first guide rails 104 are provided on the fixed plate 103. The two first guide rails 104 are distributed symmetrically. The fixed plate 103 has two sets of scissor bars 9, and the scissor bars 9 have a support plate 10. One end of the bottom of the scissor bar 9 is connected to the fixed plate 103, and the other end of the bottom of the scissor bar 9 is slidably connected to the first guide rail 104 through a sliding sleeve.

[0044] The bottom of the support plate 10 is provided with a second guide rail 1002, and the top end of the scissor bar 9 is connected to the support plate 10 via a rotating bracket, and the other end of the scissor bar 9 is slidably connected to the second guide rail 1002 via a sliding sleeve.

[0045] The second drive motor 11 is equipped with an adjusting screw 1101, which is rotatably connected to the fixed plate 103 via a bearing seat. A threaded sleeve 1102 is slidably installed on the adjusting screw 1101 via a thread, and the threaded sleeve 1102 is installed at the top middle position of the connecting rod 1103. Both ends of the connecting rod 1103 are connected to the sleeves of the rotating frame at the bottom of the scissor lift 9. This device is powered by the second drive motor 11. By rotating the adjusting screw 1101, the threaded sleeve 1102 drives the connecting rod 1103 to slide, which in turn drives the sleeve of the rotating frame at one end of the scissor lift 9 to slide along the first guide rail 104 and the second guide rail 1002. The scissor lift 9 can drive the support plate 10 to slide upward, thereby simultaneously driving the pressure ring 3 to rise steadily and slowly. This structure is simple and easy to use and operate.

[0046] The specific usage and function of this embodiment: In this invention, after the upper mold 12 and the lower mold 4 complete the stamping of the material plate, the first drive motor 8 provides power, and the gear 802 meshes to drive the first toothed plate 603 to slide along the slide groove of the top mounting bracket 6. The sliding block 601 pushes the support block 501 to make the lifting member 5 slide upward. The lifting member 5 can lift the formed cover part upward, so that it can quickly detach from the lower mold 4, which saves the trouble of manual detachment. When the upper mold 12 pushes the pressure ring 3 downward, the support plate 10 and the pressure ring 3 are connected. The limiting clip 1001 passes through the through hole 303 and is located in the slide groove of the bottom mounting bracket 7. The gear 802 meshes to drive the first toothed plate 603 to slide along the slide groove of the top mounting bracket 7. The second toothed plate 701 slides along the groove of the bottom mounting bracket 7, causing the limiting block 702 to engage with the limiting piece 1001. This prevents the pressure ring 3 from rapidly rebounding upwards under the elastic force of the support spring 102, thus avoiding deformation of the cover formed by the upward pressing of the pressure ring 3 and effectively ensuring product quality. Power is provided by the second drive motor 11. By adjusting the screw 1101, the threaded sleeve 1102 drives the connecting rod 1103 to slide, causing the sleeve of the rotating frame at one end of the scissor bar 9 to slide along the first guide rail 104 and the second guide rail 1002. The scissor bar 9 can drive the support plate 10 to slide upwards, thereby simultaneously causing the pressure ring 3 to rise steadily and slowly upwards. This structure is simple and easy to use.

[0047] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
