Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to an automotive parts stamping and forming apparatus. Background Technology

[0002] Automotive metal connectors refer to metal parts used to connect, fix, and support automotive components. These connectors play a crucial role in automobile manufacturing, ensuring the structural stability of the vehicle, the secure connections between components, and significantly impacting overall vehicle performance and safety. U-shaped metal connectors (such as...) Figure 10 As shown, the most common automotive metal connectors require stamping for manufacturing.

[0003] Currently, the stamping process for U-shaped metal connectors has the following drawbacks: 1. During the stamping process, a sheet metal needs to be placed in the stamping machine, its position manually adjusted, and then stamped. Only after the stamped U-shaped metal connector is removed can the next U-shaped metal connector be stamped. This process requires stamping sheet metal one by one, significantly reducing production efficiency. 2. Although the sheet metal's position is manually adjusted before stamping, effective restraint is not applied, causing the sheet metal to shift during the stamping process. Inaccurate stamping position can affect the dimensional accuracy and shape of the stamped parts. Due to positional deviation, the stamped products may not meet specifications, leading to product scrap and increased production costs. 3. During the stamping process, the semi-circular grooves on both sides of the U-shaped metal connector are not supported. If stamped directly, the grooves of the U-shaped metal connector will deform due to uneven pressure, thus damaging the integrity of the grooves. Furthermore, excessive tensile force during stamping can cause material tearing, making the stamped U-shaped metal connector unable to meet usage requirements and leading to product scrap.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This automotive parts stamping forming device, through the coordinated use of a stamping mechanism, a positioning mechanism, and an alignment mechanism, adopts an integrated positioning and stamping mode to simultaneously stamp multiple U-shaped metal connectors. It can automatically calibrate and fix the sheet metal position before stamping, ensuring the dimensional accuracy and shape consistency of the U-shaped metal connectors. Simultaneously, through internal support positioning and groove alignment correction, it effectively prevents material deformation and tearing, improving product quality and reducing scrap rates. Furthermore, the device supports simultaneous stamping of multiple parts, significantly improving production efficiency. After stamping, it automatically lifts the formed parts, facilitating quick and safe removal by workers, reducing labor intensity and operational risks. This comprehensively optimizes production costs and operational efficiency, achieving an automated and high-precision production process.

[0019] 2. This automotive parts stamping forming device, through the coordinated use of the stamping mechanism and the positioning mechanism, uses the downward pressure of stamping to synchronously support and position the holes of multiple sheet metals. This automatically calibrates and limits the position of the sheet metals before stamping, ensuring the precise position of the sheet metals during the stamping process. This improves the dimensional accuracy and shape consistency of the stamped parts, ensures the stability of the quality of U-shaped metal connectors, and eliminates the need for manual intervention, reducing product scrap rate and production costs.

[0020] 3. This automotive parts stamping forming device, through a set alignment mechanism, aligns and corrects the groove part before stamping the U-shaped metal connector, further calibrating the position of the sheet metal. At the same time, the alignment plate is embedded in the groove so that it can move with the groove. It can support the groove throughout the stamping process to prevent the groove from deforming due to uneven force and reduce the risk of material tearing. This ensures that the shape and size of the groove remain consistent during the stamping process, thereby improving the precision of the product.

[0021] 4. This automotive parts stamping forming device, through the set stamping mechanism, presses and fixes the positioned sheet metal, ensuring the accuracy of the sheet metal position during the stamping process, further improving the dimensional accuracy and shape consistency of the stamped parts, and can simultaneously perform stamping forming operations on multiple U-shaped metal connectors, thereby greatly improving production efficiency and reducing the time required for production.

[0022] 5. The automotive parts stamping forming device, through the positioning mechanism, simultaneously lifts multiple U-shaped metal connectors after stamping, making it easier for workers to pick up the formed U-shaped metal connectors. This eliminates the need for workers to bend over or reach for the parts, improving operational efficiency and reducing the time workers spend operating near the stamping machine, thus reducing safety risks caused by improper operation.

[0036] Please see Figure 1 and Figure 2 The I-shaped carrier 2 is provided with a positioning mechanism 5 for internal support calibration and limiting of the holes of the U-shaped metal connector plate; the positioning mechanism 5 includes a mating part 51 provided on the I-shaped carrier 2 to cooperate with the pressing part 43, an inner support part 52 provided on the I-shaped carrier 2 to cooperate with the mating part 51, and a discharge part 53 for uniformly ejecting and discharging the formed U-shaped metal connector.

[0037] Please see Figure 1 The support frame 1 and the I-shaped carrier 2 are both provided with an alignment mechanism 6 for supporting the groove of the U-shaped metal connector plate. The alignment mechanism 6 includes an alignment part 61 provided on the I-shaped carrier 2 for secondary alignment of the U-shaped metal connector plate. The alignment part 61 is provided with a support part 62, and the support frame 1 is provided with a synchronization part 63 for providing power to the alignment part 61.

[0038] Please see Figure 1 and Figure 2 The drive unit 41 includes a cylinder 411, a first connecting plate 412 and a connecting column 413. The cylinder 411 is fixedly installed on the upper end of the L-shaped support frame 3. The first connecting plate 412 located above a plurality of I-shaped carrier seats 2 is fixedly installed on the telescopic end of the cylinder 411. The connecting column 413 corresponding to the I-shaped carrier seats 2 is fixedly installed on the lower end face of the first connecting plate 412.

[0039] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The execution unit 42 includes a first slide rail 421, an inverted U-shaped stamping block 422, a force-bearing plate 423, a guide rod 424, and a first spring 425. The upper end face of the I-shaped carrier 2 is fixedly installed with the front and rear symmetrical first slide rails 421. The inverted U-shaped stamping block 422 is slidably installed between the front and rear symmetrical first slide rails 421. The center of the upper end face of the inverted U-shaped stamping block 422 is fixedly installed with a force-bearing plate 423 that is fixedly connected to the corresponding connecting column 413. The groove of the inverted U-shaped stamping block 422 is provided with a front and rear symmetrical first sliding hole. The guide rod 424 is slidably installed in the first sliding hole. The first spring 425, which is sleeved on the guide rod 424, is fixedly installed on the inverted U-shaped stamping block 422.

[0040] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The pressing part 43 includes a pressing block 431, a positioning hole 432, a second spring 433, and a contact plate 434. The lower ends of the front and rear symmetrical guide rods 424 are fixedly installed with a pressing block 431 corresponding to the groove of the inverted U-shaped stamping block 422. The lower end surface of the pressing block 431 is provided with a front and rear symmetrical positioning hole 432. The second spring 433 is fixedly installed in the positioning hole 432. The lower end of the second spring 433 is fixedly installed with a contact plate 434 that is slidably connected to the positioning hole 432.

[0041] Please see Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 The mating part 51 includes a positioning post 511, a third spring 512, a slide cylinder 513, and a hinge rod 514. The upper end face of the I-shaped carrier 2 is fixedly installed with a positioning post 511 corresponding to the alignment hole 432. The upper end of the positioning post 511 is slidably installed with a slide cylinder 513. The upper end face of the slide cylinder 513 is fixedly installed between the upper end face of the slide cylinder 513 and the upper end face of the positioning post 511. The lower end of the slide cylinder 513 is hinged with a number of hinge rods 514 in a circumferential array.

[0042] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 The inner support part 52 includes a limiting slide 521, an inner support slider 522, and an arc-shaped abutment 523. The upper end face of the I-shaped carrier 2 is provided with a limiting slide 521 corresponding to a plurality of hinge rods 514. The inner support slider 522, which is hinged to the corresponding hinge rod 514, is slidably installed in the limiting slide 521. The arc-shaped abutment 523 is fixedly installed on the upper end face of the inner support slider 522.

[0043] When stamping and forming U-shaped metal connector plates, the worker first places the plate on the upper surface of the I-shaped carrier 2, and makes the positioning post 511 just inside the hole of the plate. After placing the plates one by one on multiple I-shaped carriers 2, the loading operation of multiple plates is completed.

[0044] Next, the cylinder 411 is activated so that its extension end presses down the first connecting plate 412, and simultaneously presses down the force plate 423 through the connecting column 413. The force plate 423 then presses the inverted U-shaped stamping block 422 downward. At this time, the first slide rail 421, which is symmetrical in front and behind, limits the downward movement direction of the inverted U-shaped stamping block 422. Initially, the pressing block 431 is pushed out of the groove of the inverted U-shaped stamping block 422 under the elastic force of the first spring 425.

[0045] The cylinder 411 continues to move downward, causing the inverted U-shaped stamping block 422 to move further down. This causes the contact plate 434 inside the pressing block 431 to first contact the upper end face of the slide cylinder 513. Under the pressure of the second spring 433, the contact plate 434 will press the slide cylinder 513 downward. The descent of the slide cylinder 513 will cause the hinge rods 514 around it to open outward, thereby pushing the inner support slider 522 to move away from the corresponding positioning post 511 in the limiting slide 521 until the expanded arc-shaped abutment 523 abuts against the inner ring wall of the plate hole. At this time, the cylinder 411 stops running. The expanded arc-shaped abutment 523 provides synchronous internal support for the holes in front and behind the plate, thereby automatically calibrating and limiting the position of the plate before stamping to ensure the accurate position of the plate during the stamping process.

[0046] Please see Figure 1 , Figure 5 and Figure 6 The alignment part 61 includes a second slide rail 611, an alignment slider 612, an arc-shaped slide rail 613, and a compensation groove 614. The I-shaped carrier 2 is fixedly installed with the left and right symmetrical second slide rail 611. The alignment slider 612 is slidably installed in the second slide rail 611. The side wall of the alignment slider 612 that is close to each other is an arc surface. The arc surface of the alignment slider 612 is provided with the front and back symmetrical arc-shaped slide rail 613. The left and right side walls of the I-shaped carrier 2 are provided with symmetrical compensation grooves 614.

[0047] Please see Figure 1 , Figure 5 and Figure 8 The support part 62 includes a slide plate 621, an alignment plate 622, and a tension spring 623. The slide plate 621 is slidably mounted on the front and rear symmetrical arc-shaped slide rails 613. The alignment plate 622, which is used to support the groove of the U-shaped metal connector plate, is fixedly mounted on the slide plate 621. The left and right symmetrical semi-circular barrier plates are fixedly mounted on the alignment plate 622. The tension spring 623, which is fixedly connected to the slide plate 621, is fixedly mounted on the arc surface of the alignment slider 612 through an arc groove.

[0048] Please see Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The synchronization unit 63 includes a third connecting plate 631, a bidirectional screw 632, and a motor 633. The bidirectional screw 632 is rotatably mounted on the upper end face of the support frame 1 through a bearing seat. The bidirectional screw 632 is threadedly connected to the left and right symmetrical third connecting plates 631. The lower ends of several alignment sliders 612 on the same side are fixedly connected to the third connecting plate 631. The motor 633, whose output end is fixedly connected to the bidirectional screw 632, is fixedly mounted on the support frame 1.

[0049] In specific operation, after the stamping mechanism 4 and the positioning mechanism 5 work together to fix the sheet metal once, the motor 633 is started to rotate the bidirectional screw 632, thereby causing the alignment sliders 612 on both sides to move synchronously towards the I-shaped carrier 2 through the third connecting plate 631. At this time, the slide plate 621 is at the top of the arc-shaped slide 613 under the action of the tension spring 623, and the alignment plate 622 is flush with the upper surface of the I-shaped carrier 2. As the left and right symmetrical alignment sliders 612 move closer to each other, the alignment plates 622 on both sides will simultaneously insert into the groove of the sheet metal. When the alignment sliders 612 on both sides are in contact with the I-shaped carrier 2, the alignment plates 622 will be stuck into the groove of the sheet metal. The groove of the sheet metal is located between the left and right symmetrical semi-circular barrier plates. The position of the sheet metal is corrected again by aligning the groove of the sheet metal, and the position of the sheet metal is further calibrated.

[0050] Then, the cylinder 411 can be activated to continue lowering the inverted U-shaped stamping block 422, causing the pressing block 431 to continue lowering. At this time, the slide cylinder 513 can no longer move down, thereby moving the contact plate 434 up and squeezing the second spring 433 until the pressing block 431 presses the plate against the upper surface of the I-shaped carrier 2. At this time, the pressing block 431 stops moving down, thereby pressing and fixing the positioned plate, thus ensuring the accuracy of the plate position during the stamping process once again.

[0051] Continue to start the cylinder 411 to bring the inverted U-shaped stamping block 422 down. At this time, the pressing block 431 will retract into the groove of the inverted U-shaped stamping block 422. The inverted U-shaped stamping block 422 simultaneously performs stamping and forming operations on multiple plates to greatly improve production efficiency.

[0052] During the stamping process, the grooved part of the sheet metal will gradually rotate downwards. The grooved part of the sheet metal is located between the left and right symmetrical semi-circular baffles. Therefore, the semi-circular baffles will follow the sheet metal and move the alignment plate 622 along the arc-shaped slide 613, thereby providing support for the shape of the groove during the stamping process to prevent the groove from deforming due to uneven force. The compensation groove 614 provides displacement space for the alignment plate 622.

[0053] Please see Figure 1 , Figure 2 and Figure 8 The discharge section 53 includes an equipment base 531, an electric push rod 532, a second connecting plate 533, a push rod 534, and a top rod 535. The I-shaped carrier 2 and the support frame 1 are provided with a third sliding hole corresponding to the I-shaped carrier 2. The push rod 534 is slidably installed in the third sliding hole. The lower end of the support frame 1 is fixedly installed with the electric push rod 532 through the equipment base 531. The lower ends of several push rods 534 are fixedly installed with a second connecting plate 533 that is fixedly connected to the telescopic end of the electric push rod 532. The upper end of the push rod 534 is hinged to the top rod 535 located in the third sliding hole through a torsion spring.

[0054] In specific operation, after completing the stamping and forming of multiple U-shaped metal connectors, the reverse start cylinder 411 causes the inverted U-shaped stamping block 422 to move away from the I-shaped carrier seat 2. At this time, the pressure on the slide cylinder 513 and the U-shaped metal connectors disappears. Under the action of the third spring 512, the slide cylinder 513 moves upward, releasing the inner support lock of the positioning mechanism 5.

[0055] At this point, the electric push rod 532 can be activated, causing it to move upwards simultaneously with the push rod 534 via the second connecting plate 533. This push rod 534 then pushes the top rod 535 upwards, thereby simultaneously ejecting multiple stamped U-shaped metal connectors from the I-shaped carrier 2. After disengaging from the third sliding hole, the top rod 535 will swing to the right under the action of the torsion spring, thus placing the U-shaped metal connectors in a position easily accessible to the worker. After the worker collects the U-shaped metal connectors one by one, the electric push rod 532 can be activated in reverse to continue the stamping of the next set of U-shaped metal connectors.

[0056] Please see Figures 1-10 Working principle: When making U-shaped metal connectors, the worker first places the plate on the upper surface of the I-shaped carrier 2, and makes the positioning post 511 just inside the hole of the plate. Then, the same operation is performed to complete the loading operation of multiple plates. Then, the cylinder 411 is started and the drive unit 41 cooperates with the execution unit 42 to press down the inverted U-shaped stamping block 422. The stamping mechanism 4 cooperates with the positioning mechanism 5 to make the expanded arc-shaped abutment 523 abut against the inner ring wall of the hole of the plate, and provide synchronous internal support for the holes at the front and rear of the plate. At this time, the cylinder 411 stops running.

[0057] Then, the motor 633 is started and the alignment mechanism 6 is used to align the plate groove to correct the position of the plate again. Then, the cylinder 411 can be started to make the inverted U-shaped stamping block 422 continue to descend, so that the pressing block 431 presses the plate against the upper surface of the I-shaped carrier 2, thereby pressing and fixing the positioned plate. The inverted U-shaped stamping block 422 descends, so that it can perform stamping and forming operations on multiple plates at the same time.

[0058] After the stamping of multiple U-shaped metal connectors is completed, the reverse-start cylinder 411 moves the inverted U-shaped stamping block 422 away from the I-shaped carrier seat 2. At this time, the pressure on the slide cylinder 513 and the U-shaped metal connectors disappears. Therefore, under the action of the third spring 512, the slide cylinder 513 is moved upward, releasing the inner support lock of the positioning mechanism 5. Then, the electric push rod 532 places multiple U-shaped metal connectors in a position that is easy for the worker to pick up through the discharge part 53. After the worker collects the U-shaped metal connectors one by one, the electric push rod 532 can be reversed to continue the stamping of the next set of U-shaped metal connectors.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
