Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production, and more particularly to a stamping device for a panoramic sunroof crossbeam die. Background Art

[0002] The panoramic sunroof crossbeam is a crucial component of the vehicle's sunroof structure. It enhances the overall rigidity of the sunroof, withstands the significant loads from vehicle rollovers, side impacts, and overhead pressure, prevents excessive roof collapse, and protects occupants. Panoramic sunroof crossbeams are typically manufactured using stamping.

[0003] Prior art, such as Chinese patent publication number CN109807215A, discloses a stamping device for a panoramic sunroof crossbeam mold. The device comprises a lower die body, an upper die body, a press core, a single air path system, a support frame, and a stamping device. The upper and lower dies cooperate to form the press core, ensuring more precise production of the sunroof crossbeam. The lower die body is equipped with independent guide pin and sleeve assemblies, which are provided with holes. During the stamping process, each independent guide pin and sleeve assembly aligns with the holes in the upper die body, ensuring precise closing of the upper and lower dies.

[0004] However, during the use of the stamping equipment, due to the wear and deformation of the independent guide pin and guide sleeve components, the transmission error of the mold, and the guide pin hole matching clearance and other factors, slight deviations will occur in the positions of the upper and lower molds. The above-mentioned simple guide pin hole matching structure cannot be automatically corrected, which will cause further wear of the guide pins and other components, and the position deviation of the upper and lower molds will be aggravated, affecting the molding quality of the panoramic sunroof beam.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0047] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0048] Example 1:

[0049] like Figure 1 、 Figure 2 As shown, the present invention provides a stamping device for a panoramic sunroof crossbeam mold, comprising:

[0050] A punching machine body 1 is provided with a lower die 2 and a movable upper die 3;

[0051] The guide member includes a guide column 5 provided at the top end of the lower mold 2 and a guide hole 6 provided at the bottom end of the upper mold 3, and the guide column 5 and the guide hole 6 are provided correspondingly;

[0052] The buffer unit 7 is provided in the guide hole 6 and is used to reduce the impact on the top end of the guide column 5;

[0053] The active positioning unit 8 is provided on one side of the guide hole 6 and is used to adjust the position of the guide post 5 in the guide hole 6 .

[0054] The working principle and beneficial effects of the above technical solution are:

[0055] The present invention provides a stamping device for a panoramic sunroof crossbeam mold. The device is provided with a fixed lower mold 2 and a movable upper mold 3. A guide post 5 is provided on the lower mold 2, and a guide hole 6 is provided on the upper mold 3. During the mold closing process, the relative sliding of the guide post 5 and the guide hole 6 guides the mold closing process to ensure mold closing accuracy. A buffer unit 7 is provided in the guide hole 6 to reduce the impact generated during mold closing. An active positioning unit is provided in the upper mold 3. Since there is a clearance fit between the guide post 5 and the guide hole 6, when a small deviation occurs between the guide post 5 and the guide hole 6, the active positioning unit 8 is activated to reposition and correct the guide post 5.

[0056] Through the above-mentioned structural design, the present invention provides a stamping equipment for a panoramic sunroof crossbeam mold, in which a buffer unit 7 and an active positioning unit 8 are arranged in the upper mold 3. The buffer unit is used to reduce the wear and deformation of the mold and components, and the active positioning unit is used to quickly correct the positioning of the guide column 5, thereby further reducing the position deviation of the upper and lower molds, reducing the wear of the guide parts caused by misalignment, preventing the guide parts from further wear causing the mold closing deviation to be aggravated, realizing automatic position correction in the stamping process, and improving the forming quality of the panoramic sunroof crossbeam.

[0057] Example 2:

[0058] like Figure 1 As shown, on the basis of the above embodiment 1, a punching cylinder 4 is provided at the top of the punching machine body 1, and the telescopic end of the punching cylinder 4 is connected to the upper die 3.

[0059] The working principle and beneficial effects of the above technical solution are:

[0060] The punch cylinder 4 is used to provide power for the movement of the upper die 3. When the punch cylinder 4 is activated, its bottom end extends, pushing the upper die 3 downward toward the lower die 2 for mold closing while maintaining a certain mold closing pressure. After molding is complete, the punch cylinder 4 is activated to retract its bottom end, driving the upper die 3 to separate from the lower die 2.

[0061] Example 3:

[0062] like Figure 3 As shown, based on the above embodiment 1, the buffer unit 7 includes:

[0063] The fixing seat 11 is installed on the top of the guide hole 6;

[0064] The balancing seat 12 is disposed below the fixing seat 11 and spaced apart by a preset distance. The balancing seat 12 and the fixing seat 11 are connected via a buffer ball 13.

[0065] The elastic member 14 is configured to be arc-shaped and connected between the edge of the fixing seat 11 and the side wall of the balancing seat 12 . Four elastic members 14 are evenly arranged along the circumference of the balancing seat 12 .

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] When guide pin 5 slides along guide hole 6 to its top end, it contacts balancing seat 12. This pressure exerted by guide pin 5 on balancing seat 12 causes the center of balancing seat 12 to squeeze and deform cushioning ball 13. Cushioning ball 13, made of elastic material, acts as a primary cushioning element for guide pin 5. Simultaneously, elastic elements 14 surrounding balancing seat 12 provide a spring force, enhancing the cushioning effect on guide pin 5 and reducing impact during mold closing, thus acting as a secondary cushioning element for guide pin 5. Four elastic elements 14 are evenly spaced along the circumference to facilitate balanced resetting of guide pin 5.

[0068] Example 4:

[0069] like Figure 3 As shown, based on the above embodiment 3, the balancing seat 12 includes:

[0070] The first piston cylinder 15 is provided on the fixing seat 11 and the balancing seat 12 , and both ends of the elastic member 14 are connected to the first piston rods of the two first piston cylinders 15 respectively;

[0071] The second piston cylinders 16, four second piston cylinders 16 are evenly arranged in the balance seat 12, and the second piston cylinders 16 are connected to the first piston cylinders 15 in a one-to-one correspondence;

[0072] The pressure plate 17 is connected to the second piston rod 18 of the second piston cylinder 16 , and the extension and contraction direction of the second piston rod 18 is perpendicular to the axis direction of the balance seat 12 .

[0073] The airbags 19 are four airbags 19 disposed on the bottom surface of the fixing seat 11 , and the airbags 19 are in contact with the pressure plate 17 .

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] When there is no positional deviation between the guide post 5 and the guide hole 6 or the deviation is small, the four elastic members 14 are evenly stressed and their deformation is within a preset range. The squeezing force on the first piston cylinder 15 is also within a preset range. The gas in the first piston cylinder 15 enters the second piston cylinder 16, pushing its second piston rod 18 to extend. The pressure plate 17 moves and squeezes the airbag 19. The deformation of the airbag 19 is within a preset range. The airbag 19 cushions the pressure plate 17, thereby providing a third level of cushioning for the balance seat 12. When the guide post 5 is removed from the guide hole 6, the elastic members and the piston cylinder return to their original positions under the action of the elastic force.

[0076] Example 5:

[0077] On the basis of the above-mentioned embodiment 4, an air pressure sensor is provided in the airbag 19 , and the controller is electrically connected to the air pressure sensor and the active positioning unit 8 .

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] A pressure sensor is installed within airbag 19. When the ends of guide post 5 and guide hole 6 are deformed and their positional deviation is large, the four elastic members 14 are subjected to uneven force, with one or two elastic members 14 subjected to greater force. At this time, the piston in the connected first piston cylinder 15 moves significantly, and gas flows into the second piston cylinder 16, causing the second piston rod 18 to extend significantly. This squeezes the airbag 19 through the pressure plate 17, deforming it and causing the air pressure within the airbag 19 to exceed a preset range. The controller obtains the detection data from the pressure sensor and, if it detects that the pressure value exceeds the preset range, activates the active positioning unit 8 to reposition and correct the position of guide post 5. This effectively realizes real-time detection of the position state, facilitates the determination of the timing of positioning correction, and improves the automatic adjustment capability of the equipment.

[0080] Example 6:

[0081] like Figure 4 、 Figure 5 As shown, based on the above embodiment 1, the active positioning unit includes:

[0082] Positioning cylinder 21, the positioning cylinder 21 is arranged in the positioning cavity on one side of the guide hole 6, and the telescopic direction of the positioning cylinder 21 is perpendicular to the axial direction of the guide hole 6;

[0083] The positioning frame 22 is connected to the telescopic end of the positioning cylinder 21 and is slidably disposed in the positioning cavity;

[0084] The first positioning block 23 is connected to the side of the positioning frame 22 close to the guide hole 6. The two first positioning blocks 23 are symmetrically arranged on both sides of the guide hole 6. The first positioning block 23 is provided with a first positioning arc surface 24, and the first positioning arc surface 24 is adapted to the inner wall of the guide hole 6; a permanent magnet is arranged in the guide column 5.

[0085] A second magnetic positioning block 25 is provided at the center of the positioning frame 22 . A second positioning arc surface 26 is provided on the second positioning block 25 . The second positioning arc surface 26 is adapted to the inner wall of the guide hole 6 .

[0086] The working principle and beneficial effects of the above technical solution are:

[0087] When the active positioning unit 8 is in use, the positioning cylinder 21 is activated to drive the positioning frame 22 to move, so that the first positioning block 23 and the second positioning block 25 are simultaneously close to the guide hole 6. The diameter of the first positioning arc surface 24 and the diameter of the second positioning arc surface 26 are equal to the diameter of the inner wall of each guide hole 6. The two first positioning arc surfaces 24 are set on both sides of the second positioning arc surface 26, so that the first positioning arc surface 24 and the second positioning arc surface 26 are flush with the inner wall of the guide hole 6, forming a positioning arc surface; at the same time, under the magnetic force of the second positioning block 23, the guide column 5 is attracted to the positioning arc surface and returned to the side where the active positioning unit is set. That is, the side where the active positioning unit is set is used as the reference surface, eliminating the mold closing gap on this side; when the guide column 5 slides along the inner wall of the guide hole 6 on this side, the mold closing is accurate.

[0088] Through this structural design, the active positioning unit 8 utilizes two fixed positioning blocks and a magnetic positioning block. During positioning correction, the magnetic force pulls the guide post 5 back toward the guide hole 6. This eliminates unilateral transmission gaps, ensuring accurate mold closing and reducing positioning difficulty. The magnetic positioning block provides power for the positioning process.

[0089] Example 7:

[0090] like Figure 4-Figure 6 As shown, based on the above embodiment 6, a magnetic switching component is provided on the positioning frame 22 and the second positioning block 25, and the magnetic switching component includes:

[0091] The magnetic block 31 is rotatably connected to the cavity of the second positioning block 25 via a rotating shaft 32, and a permanent magnet is provided on one side of the magnetic block 31;

[0092] Gear 33, which is connected to the rotating shaft 32 and arranged outside the second positioning block 25;

[0093] The turning cylinder 34 is mounted on the support frame 36 of the positioning frame 22;

[0094] The rack 35 has two ends slidably connected to the support frame 36 , and the rack 35 is meshed with the gear 33 , and one end of the rack 35 is connected to the telescopic end of the flip cylinder 34 .

[0095] The working principle and beneficial effects of the above technical solution are:

[0096] When the magnetic switching assembly is in use, the flip cylinder 34 is started to drive the rack 35 to move, and the rack 35 engages with the gear 33 for transmission, driving the rotating shaft 32 to rotate, and then driving the magnetic block 31 to rotate, so that the position of the permanent magnet on the magnetic block 31 changes. When the active positioning unit is performing positioning correction, the magnetic switching assembly is started to rotate the permanent magnet of the magnetic block 31 to face the guide hole 6. At this time, the magnetic attraction force of the magnetic block 31 on the guide column 5 is the largest, providing sufficient power for the positioning correction process. When the active positioning unit is positioned and the upper and lower molds are separated, the magnetic switching assembly is started to rotate the permanent magnet of the magnetic block 31 to face away from the guide hole 6. At this time, the magnetic attraction force of the magnetic block 31 on the guide column 5 is small. At the same time, as the positioning cylinder 21 is retracted, the adsorption on the guide column 5 is released, and the mold opening process is not hindered.

[0097] Through the above structural design, the magnetic block 31 is set to a rotating structure, and the position of the magnetic surface of the magnetic block 31 is adjustable, which can be adjusted to adapt to the positioning and mold opening process, providing sufficient power for the positioning correction process, while not hindering the mold opening process, thereby improving the flexibility of the active positioning unit.

[0098] Example 8:

[0099] like Figure 4 、 Figure 5 As shown, on the basis of the above-mentioned embodiment 7, the positioning frame 22 is configured as a double-layer structure, including two positioning plates 37 spaced a preset distance apart, and the two positioning plates 37 are connected by a connecting rod 38; a shock-absorbing rod 39 is also movably arranged between the two positioning plates 37, and a spring is provided on the shock-absorbing rod 39, and both ends of the spring are in contact with the two positioning plates 37.

[0100] The working principle and beneficial effects of the above technical solution are:

[0101] The positioning frame 22 is configured as a double-layer structure, providing stable support for the first positioning block 23 and the second positioning block 25. The two positioning plates 37 are stably connected by a connecting rod 38. When the guide post 5 contacts the positioning blocks under the action of magnetic force, the resulting impact is transmitted to the positioning blocks, then to one positioning plate 37, where it is dissipated by the shock-absorbing rod 39, providing a shock-absorbing effect. This prevents deformation of the guide post 5 during the positioning process, ensuring accurate and reliable positioning.

[0102] Example 9:

[0103] like Figure 4、 Figure 5 As shown, based on the above-mentioned embodiment 7, the first positioning blocks 23 are set into multiple groups and arranged axially at intervals along the guide hole 6; the sensing blocks 41 are symmetrically arranged on both sides of the positioning frame 22, and the detection ends of the sensing blocks 41 abut against the side walls of the guide column 5 for detecting the contact pressure with the guide column 5; the sensing blocks 41 are set into two groups, upper and lower.

[0104] The working principle and beneficial effects of the above technical solution are:

[0105] When adjusting the position of the guide column 5, due to the transmission gap between the guide column 5 and the guide hole 6, the deflection and deformation of the guide column 5 during the adjustment process will cause inconsistencies in the upper and lower positioning states. Therefore, the first positioning blocks 23 of the automatic positioning unit are set to multiple groups to perform adsorption positioning on multiple points above and below the guide column 5, thereby improving the consistency of the upper and lower positioning of the guide column 5. At the same time, a sensing block 42 is set, and the detection end of the sensing block 41 contacts the side wall of the guide column 5. When the detection value deviation of the sensing block 41 in the upper and lower positions is within the preset range, it indicates that the upper and lower positioning of the guide column 5 is consistent, and the positioning correction process is effective. This effectively realizes the evaluation feedback of the active positioning process, helps to identify the positioning failure state, and provides a basis for the maintenance of the automatic positioning unit.
