Description

Technical Field

[0001] This invention relates to the field of automotive roof stamping technology, specifically to an automotive roof stamping die. Background Technology

[0002] The car roof is the cover on the top of a car body, and is a body panel. It is mainly made of metal or glass and has little impact on the overall rigidity of the car body, but it needs to have a certain strength and rigidity to ensure safety. The roof needs to transition smoothly with the front and rear window frames and pillars to optimize aerodynamic performance and visual aesthetics. Reinforcing beams and heat insulation pads are often added inside to improve strength, sound insulation and heat insulation. Factories generally shape the car roof by stamping with molds and then process it through cutting and other processes.

[0003] To improve shaping accuracy and production efficiency and avoid repeated positioning, traditional automotive roof stamping dies generally adopt a one-time forming method during stamping. However, during the stamping process, the local deformation of the profile is relatively large, requiring high compensation values ​​for calculation and consideration, and is prone to damage to the profile. In addition, some automotive roofs have some angles due to design reasons, and some angles can cause the automotive roof to be stuck in the mold after stamping, making it difficult to demold and even damaging the mold.

Three sets of guide positioning components 2 are provided on both the front and rear sides of the transfer module 1. Each guide positioning component 2 is provided with a clamping positioning component 3. The clamping positioning component 3 includes a lower slide seat 31 and an upper slide seat 32, which are slidably disposed on the guide positioning component 2. A male mold is slidably disposed in the upper slide seat 32. A longitudinal stamping component 4 connected to the male mold is disposed on the top. A lateral stamping component 5 is disposed in the lower slide seat 31. An inlaid female mold 52 is disposed on the lateral stamping component 5.

[0032] In the above description, each clamping and positioning component 3 is guided and centered by the corresponding guide positioning component 2. The profile is transferred by the transfer module 1 and passes through three sets of clamping and positioning components 3 in sequence for graded stamping. During the process of passing through each clamping and positioning component 3, the profile is clamped and positioned by the clamping and positioning component 3. Then, the profile is stamped by the side stamping component 5 and the longitudinal stamping component 4. The side stamping component 5 stamps the included angle of the profile. By splitting the mold, the car roof is prevented from being stuck in the mold after stamping, which facilitates the demolding and transfer of the car roof.

[0033] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 9 As shown, the transfer module 1 includes a base 11 and a transfer belt 14. The base 11 is a U-shaped frame with the opening facing upward, and fixed plates 12 are respectively arranged at both ends along the front and rear sides. Support rods 13 are respectively arranged at both ends of the fixed plates 12. The support rods 13 are U-shaped frames with the opening facing inward. Two pairs of transfer belts 14 that abut against each other are arranged in a mirror image from left to right and are respectively rotatably mounted on the U-shaped frame (each transfer belt 14 is equipped with a servo motor with the same rotation speed).

[0034] As described above, the profile is placed horizontally and clamped between the two transfer belts 14 on both sides. After the transfer belt 14 rotates, it drives the profile forward and passes through three sets of clamping and positioning components 3 for graded stamping (the transfer belt 14 stops rotating during the stamping process). After the stamping of the car roof is completed, it is automatically taken away from the car roof.

[0035] Combined with appendix Figure 4 Appendix Figure 5 As shown, the guide positioning component 2 includes a positioning frame 21, which is a U-shaped frame with the opening facing upward. Three positioning frames are provided on the front and back of the base 11. A pair of guide rods 22 are vertically arranged on the inner side of each positioning frame 21 for easy left and right mirroring. Positioning plates 23 are horizontally arranged on the inner walls of the two side plates. Each positioning plate 23 is provided with a centering groove 24, which is provided on the clamping surface of the transfer belt 14. The centering groove 24 is arranged horizontally on the left and right and runs through the top and bottom.

[0036] Combined with appendix Figure 3 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8As shown, the lower slide seat 31 and the upper slide seat 32 are arranged vertically opposite each other, and are slidably mounted on the two guide rods 22 on the left and right sides respectively. The upper slide seat 32 has an upper clamping cavity 321 at the bottom (the upper clamping cavity 321 is vertically connected), and the lower slide seat 31 has a lower clamping cavity 311 at the top (the top of the lower clamping cavity 311 is open). A clamping hydraulic cylinder 33 is vertically mounted between the bottom and the positioning frame 21. Guide posts 37 are vertically mounted on the upper slide seat 32 on the left and right sides of the upper clamping cavity 321. A guide tube 36 is vertically mounted on the lower slide seat 31 corresponding to the guide post 37. The guide post 37 is slidably mounted in the guide tube 36. A centering slider 35 is slidably mounted in the centering groove 24. Centering flip rods 34 are hinged to the lower slide seat 31 and the upper slide seat 32 on the sides respectively, and the other end of the centering flip rods 34 is hinged to the centering slider 35 on the same side respectively.

[0037] Combined with appendix Figure 3 Appendix Figure 6 Appendix Figure 8 As shown, positioning grooves 38 are respectively misaligned on the clamping surfaces of the lower clamping cavity 311 and the upper clamping cavity 321, and positioning punches 39 are respectively provided on the lower clamping cavity 311 and the upper clamping cavity 321 of the first set of clamping and positioning components 3. The positioning punches 39 are provided corresponding to the positioning grooves 38 and are in clearance fit with the positioning grooves 38.

[0038] As described above, the lower sliding seat 31 and the upper sliding seat 32 are precisely aligned vertically after being limited by the guide column 37, the guide tube 36 and the guide rod 22, ensuring accurate positioning after clamping. They are also precisely aligned vertically by the centering sliders 35 on both sides. During the clamping and positioning of the profile by the first set of clamping and positioning components 3, the positioning punch 39 punches the shearing area of ​​the profile edge to create a concave point, which facilitates the subsequent positioning of the profile by other clamping and positioning components 3 through the positioning groove 38, preventing the profile from shifting during transportation. The profile is fixed by the clamping of the lower clamping cavity 311 and the upper clamping cavity 321, preventing displacement during the stamping process and improving the stamping effect.

[0039] Combined with appendix Figure 1 Appendix Figure 7 Appendix Figure 8 As shown, the longitudinal stamping assembly 4 includes a stamping plate 41, a stamping frame 42 is provided on the top of the upper slide block 32, the stamping plate 41 is slidably disposed in the upper slide block 32, and a stamping hydraulic cylinder 43 is provided between the top and the stamping frame 42, the bottom is connected to the male mold, the stamping hydraulic cylinder 43 is vertically disposed, and the fixed end is disposed on the stamping frame 42, and the telescopic end is disposed on the stamping plate 41.

[0040] Combined with appendix Figure 10 Appendix Figure 12 Appendix Figure 13As shown, the lateral stamping assembly 5 includes a stamping sleeve 51, which is sleeved and fixed inside the sliding seat 31. A positioning rib ring 511 is provided on the inner side wall along the circumferential direction, and an adjustment structure 53 is provided on the stamping sleeve 51 below the positioning rib ring 511. An insert-type female die 52 is provided inside the stamping sleeve 51.

[0041] Combined with appendix Figure 10 Appendix Figure 11 Appendix Figure 12 Appendix Figure 14 As shown, the adjustment structure 53 includes an adjustment frame 531. A lateral displacement screw 535 is rotatably disposed inside the stamping sleeve 51, and one end of the lateral displacement screw 535 is connected to the drive shaft of the lateral displacement motor 536 disposed on the stamping sleeve 51. The adjustment frame 531 is slidably disposed on the stamping sleeve 51, and one end is threaded onto the lateral displacement screw 535. Adjustment screws 533 are rotatably disposed on both sides of the adjustment frame 531, and one end of each adjustment screw 533 is rotatably disposed on the adjustment frame 531, and the other end is connected to the drive shaft of the adjustment motor 534 disposed on the adjustment frame 531. A pair of adjustment slides 532 are slidably disposed on the adjustment frame 531, and the opposite ends of the two adjustment slides 532 are threaded onto the corresponding adjustment screws 533.

[0042] Combined with appendix Figure 10 Appendix Figure 12 Appendix Figure 13 Appendix Figure 14 As shown, the insert-type female mold 52 includes a concave cavity 521 and a side-joining cavity 522. The concave cavity 521 is fitted and fixed inside the stamped sleeve 51 on the upper side of the positioning rib ring 511, and a machining groove 523 is opened at the bottom. Side-joining hydraulic cylinders 54 are horizontally arranged on the two adjusting slides 532 respectively. The telescopic ends of the two side-joining hydraulic cylinders 54 are arranged opposite each other and are respectively provided with mounting plates 55. The fixed ends are respectively set on the corresponding adjusting slides 532. A pair of side-joining cavities 522 are arranged opposite each other at the bottom of the concave cavity 521 (the bottom surface of the side-joining cavity 522 overlaps with the bottom surface of the concave cavity 521), and are respectively installed on the two side mounting plates 55.

[0043] In the above description, the male mold is installed in the upper slide block 32, and the insert-type female mold 52 is installed in the lower slide block 31. Through the adjustment structure 53, the two side cavities 522 are arranged to correspond to the processing slots 523. After the profile is clamped, positioned and fixed by the clamping and positioning assembly 3, the stamping hydraulic cylinder 43 is extended to drive the male mold to press down, causing the profile to deform. After deformation, part of the profile passes through the processing slots 523 and is arranged between the two side cavities 522. The two side hydraulic cylinders 54 are extended, and the part of the profile that passes through the processing slots 523 is clamped between the two side cavities 522 and deformed, completing the stamping and shaping operation. The two side hydraulic cylinders 54 are retracted to make the car roof detach from the side cavities 522, preventing the car roof from getting stuck in the side cavities 522. Then the stamping hydraulic cylinder 43 and the clamping hydraulic cylinder 33 are retracted, and the car roof is completely demolded and conveyed away by the transfer belt 14.

[0044] In specific implementations of this invention, the contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] The working principle of this invention is as follows: The male mold is installed in the upper slide block 32, and the insert-type female mold 52 is installed in the lower slide block 31. Through the adjustment structure 53, the two side cavities 522 are arranged to correspond to the processing slots 523, so that the profile is placed horizontally and clamped between the two side conveyor belts 14. After the conveyor belts 14 rotate, they drive the profile forward and pass through three sets of clamping and positioning components 3 for graded stamping. After the profile is clamped and positioned by the first set of clamping and positioning components 3, the positioning punch 39 stamps the shearing area of ​​the profile edge to create a concave point, which facilitates the subsequent positioning of the profile by other clamping and positioning components 3 through the positioning grooves 38. The first-stage stamping hydraulic cylinder 43 is controlled to extend, driving the male mold to press down and deform the profile. After deformation, part of the profile passes through the clamping and positioning components 3. The processing slot 523 is positioned between the two side cavities 522. The extension of the two side cavities 54 is controlled, and the portion of the profile passing through the processing slot 523 is clamped between the two side cavities 522 and deformed, completing the stamping and shaping operation. The retraction of the two side cavities 54 is controlled, causing the car roof to detach from the side cavities 522. The retraction of the stamping hydraulic cylinder 43 and the clamping hydraulic cylinder 33 is controlled. After the car roof detaches from the first-level clamping and positioning assembly 3, it is conveyed to the next-level clamping and positioning assembly 3 via the transfer belt 14. After the next-level clamping and positioning assembly 3 clamps, it quickly positions and adjusts its position through the positioning groove 38, and performs the next level of stamping on the car roof. After each level of stamping is completed, the car roof is automatically carried away by the transfer belt 14 for cutting, drilling, and shaping.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
