Description

Technical Field

[0001] This invention relates to the field of automotive parts stamping technology, and more particularly to a stamping positioning mechanism for automotive stamping parts. Background Technology

[0002] In the automotive manufacturing industry, stamping is a core process for producing key components such as body panels and structural parts. The dimensional accuracy and consistency of stamped parts directly determine the assembly quality and driving safety of automobiles. Among these, the stamping positioning mechanism, as a crucial piece of equipment ensuring stamping accuracy, has a significant impact on the efficiency and cost control of the entire production process. Currently, most mainstream automotive stamping part positioning mechanisms on the market rely on manual assistance for material loading and positioning. Operators must place the stamping plates one by one to designated workstations, which is not only labor-intensive but also prone to errors due to human intervention, leading to misalignment of the plates and increased scrap rates. This makes it difficult to meet the demands of large-scale automated production. Furthermore, while some semi-automatic positioning mechanisms achieve preliminary mechanical feeding, they lack stable unloading and calibration mechanisms, making the plates susceptible to positional deviations due to friction and collisions during sliding transport. Therefore, a new automotive stamping part positioning mechanism is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a stamping positioning mechanism for automotive stamping parts, which solves the problems of existing automotive stamping positioning mechanisms that rely on manual assistance for feeding and positioning, which easily leads to a high product scrap rate, and the lack of a stable feeding and calibration mechanism.

[0026] like Figure 1 and Figure 2 The illustrated stamping positioning mechanism for automotive stamping parts includes a base 1, which is used to install and fix the components in this embodiment. The base 1 is provided with: The material box assembly 2 includes a placement box 22, which is provided with a stacking groove 23 for stacking stamping plates 10. The placement box 22 has a sliding groove 24 that communicates with the stacking groove 23. In this embodiment, the stamping plate 10 is a circular plate structure, the placement box 22 is a cuboid structure, and the stacking groove 23 is a cylindrical groove. Several sets of stamping plates 10 can be manually stacked in the stacking groove 23 to facilitate subsequent feeding, unloading, positioning, stamping and other processes.

[0027] The pusher assembly 3 is used to push out a group of stamped plates 10 located at the bottom of the placement box 22 from the sliding groove 24. When the pusher assembly 3 is activated once, it will push out the stamped plate 10 located at the bottom of the stacked material groove 23 from the placement box 22 and allow the stamped plate 10 to enter the subsequent positioning process.

[0028] The unloading assembly 4 is used to push the stamping plate 10 from the pusher assembly 3 onto the positioning assembly 5. After the stamping plate 10 is pushed out of the placement box 22, it is still above the pusher assembly 3. Therefore, the unloading assembly 4 is needed to push the stamping plate 10 from the pusher assembly 3 so that the stamping plate 10 falls into the subsequent positioning process.

[0029] The positioning component 5 is used to move the stamping plate 10 to a designated position and clamp it after it falls. Because the stamping plate 10 is not fixed after falling onto the positioning component 5 due to the pushing process, it is not convenient to pick up the stamping plate 10 to the stamping position by the picking component 7. Therefore, the positioning component 5 is needed to push the fallen stamping plate 10 to the designated position and then clamp it for positioning. After the picking component 7 grasps the stamping plate 10, the positioning component 5 releases the stamping plate 10 so that the picking component 7 can smoothly remove the stamping plate 10.

[0030] The stamping assembly 6 is used to stamp the stamping plate 10 to form a product blank. Through the closing and opening operations of the upper and lower dies, the stamping plate 10 is stamped and formed into the required product blank, so as to facilitate subsequent processes such as drilling and grooving, and finally produce the finished product. After the stamping of the product blank is completed, the product blank is removed from the stamping assembly 6 by the take-up assembly 7 and moved to the designated position and placed down.

[0031] The picking component 7 is used to pick up the positioned stamping plate 10, move it to the stamping component 6, and remove the product blank after stamping. Since it is necessary to pick up the positioned stamping plate 10 to the stamping component 6 and remove the product blank after stamping, the picking component 7 automatically picks up the stamping plate 10 and the product blank, achieving automated operation, ensuring the stamping accuracy of subsequent processes, and reducing the scrap rate of stamped parts.

[0032] like Figure 3 As shown, the material box assembly 2 also includes a first fixing frame 21, which is screwed to the base 1 for easy installation and fixation of the placement box 22. The placement box 22 is screwed to the first fixing frame 21 to allow for precise adjustment of its height, enabling it to better cooperate with the pushing assembly for material pushing. The sliding groove 24 is located at the bottom of the placement box 22 and extends through the entire placement box 22. The placement box 22 is stably fixed to the base 1 by the first fixing frame 21, preventing the box from shaking due to the stacking of the stamping plates 10. At the same time, the communication structure between the stacking groove 23 and the sliding groove 24 ensures that the stamping plates 10 can be stacked in an orderly manner without any messy accumulation.

[0033] In this embodiment, the sliding groove 24 is a rectangular groove that penetrates the front and rear side walls of the placement box 22, so that the pushing assembly 3 can smoothly push the stamping plate 10 out of the placement box 22.

[0034] like Figure 3 and Figure 4As shown, the pusher assembly 3 includes a first fixed base 31, which is fixedly connected to the base 1 by screws. The first fixed base 31 is used to fix and connect the housing of the first electric push rod 32. The output end of the first electric push rod 32 is set towards the sliding groove 24. The output end of the first electric push rod 32 is also fixedly connected to a pusher plate 33. The top of the pusher plate 33 is provided with a pusher groove 34. The pusher groove 34 is used to place the lowermost set of stamping plates 10 in the stacking groove 23. The pusher plate 33 is slidably connected in the sliding groove 24.

[0035] In this embodiment, the pusher plate 33 is a rectangular plate adapted to the sliding groove 24, and the pusher groove 34 is disposed on the upper rear end surface of the pusher plate 33. The pusher groove 34 is a U-shaped groove structure with a semi-circular arc, and the depth of the pusher groove 34 is the same as the thickness of a stamping plate 10. The upper end of the groove wall of the pusher groove 34 is provided with a chamfer 35, so when the stamping plate 10 enters the pusher groove 34, there will be a certain gap between the chamfer 35 and the stamping plate 10.

[0036] like Figure 5 As shown, the feeding assembly 4 includes a rotating base 41, on which a push rod 45 is hinged and connected, and a torsion spring 44 provides elastic force to the push rod 45. The lower end of the push rod 45 is correspondingly located at the outlet of the sliding groove 24. In this embodiment, the rotating base 41 has a U-shaped structure, with its opening on one side located away from the placement box 22.

[0037] The rotating seat 41 is fixedly connected to the outer wall of the placement box 22 at the outlet of the sliding groove 24. A set of rotating shafts 42 are symmetrically fixed on both sides of the push rod 45. The rotating shafts 42 are rotatably connected to the rotating seat 41. Fixing rods 43 are fixedly installed on both sides of the rotating seat 41. Torsion springs 44 are also sleeved on the rotating shafts 42. In this embodiment, the fixing rods 43 can be positioned in front of the rotating shafts 42, one end of the torsion spring 44 is fixedly connected to the rotating shaft 42, and the other end of the torsion spring 44 is fixedly connected to the fixing rod 43.

[0038] The lower end of the push rod 45 has a V-shaped structure. The head of the V-shaped structure can be better inserted into the gap between the chamfer 35 and the stamping plate 10, and at the same time, it can facilitate the rotation of the push rod 45 by the push plate 33 and the stamping plate 10. In addition, in order to achieve a buffering effect and prevent wear on the parts of the stamping plate 10 and the push rod 45, silicone pads 46 are fixedly connected to both the front and rear sides of the V-shaped head of the lower end of the push rod 45.

[0039] The working principle of the unloading component 4: The push rod 45 is initially set vertically. When the push plate 33 moves backward and extends out of the sliding groove 24, it will push the bottom set of stamping plates 10 in the placement box 22 out of the sliding groove 24. At this time, the push plate 33 and the stamping plates 10 will drive the push rod 45 to rotate clockwise by a certain small angle. At this time, the torsion spring 44 will also be compressed. The silicone pad 46 on the front side of the push rod 45 presses against the upper end face of the stamping plate 10, assisting the stamping plate 10 to smoothly leave the sliding groove 24. When the push plate 33 continues to move backward to the limit, it will push the stamping plate 10 out of the sliding groove 24. When the pressure plate 10 is fully pushed out of the sliding groove 24, the spring force of the torsion spring 44 is released due to the presence of the chamfer 35. The push rod 45 will return to its original position and rotate counterclockwise at a small angle. At this time, the V-shaped head at the lower end of the push rod 45 will be inserted into the gap between the chamfer 35 and the stamping plate 10. At this time, the push rod 45 will no longer be pushed by the stamping plate 10, and the push rod 45 will no longer rotate counterclockwise. When the push plate 33 moves forward to return to its original position, the stamping plate 10 in the push groove 34 will be blocked by the push rod 45 and slide in the push groove 34 until the stamping plate 10 falls onto the positioning component 5.

[0040] like Figure 6 As shown, the positioning component 5 includes a second fixed base 51, which is fixedly connected to the base 1 by screws. A second electric push rod 54 is fixedly connected to one side of the top of the second fixed base 51. A push plate 55 is fixedly connected to the output end of the second electric push rod 54. A positioning block 56 is provided on the other side of the top of the second fixed base 51. The push plate 55 and the positioning block 56 cooperate to clamp and limit the stamping plate 10.

[0041] In this embodiment, the second electric actuator 54 can be disposed on the right side of the second fixed base 51, and the positioning block 56 can be disposed on the left side of the second fixed base 51. When the stamping plate 10 falls from above onto the second fixed base 51, the second electric actuator 54 is activated to drive the push plate 55 to move the stamping plate 10 toward the positioning block 56 until the stamping plate 10 is blocked by the positioning block 56. At this time, the stamping plate 10 is also clamped by the push plate 55 and the positioning block 56, completing precise positioning.

[0042] To facilitate the positioning and placement of the stamping plate 10, and to facilitate the detection of whether the stamping plate 10 has fallen into place, a circular placement plate 52 is fixedly installed on the top of the second fixing base 51. The output end of the second electric push rod 54 is positioned facing the placement plate 52, and a contact sensor 5 is installed in the middle of the placement plate 52. In this embodiment, the contact sensor 5 is electrically connected to the signal receiver 82.

[0043] like Figure 6As shown, in order to better adapt to the peripheral wall of the stamping plate 10 with a circular plate structure, two sets of positioning blocks 56 are symmetrically arranged and arranged in a triangular shape with the push plate 55 to clamp and limit the stamping plate 10. The contact surfaces of the positioning blocks 56, the push plate 55 and the stamping plate 10 are conforming to the side wall of the stamping plate 10.

[0044] In this embodiment, the push plate 55 has an arc structure, and the contact surface between the positioning block 56 and the stamping plate 10 is also an arc structure. The positioning block 56 is located on the left side of the second fixed base 51, and the second electric push rod 54 is located on the right side of the second fixed base 51. The positioning stamping plate 10 is clamped and positioned from three directions, which not only ensures the stability of the clamping structure, but also ensures the accuracy of clamping and positioning.

[0045] like Figure 7 As shown, in order to stamp the stamping plate 10 into the required product blank, the stamping assembly 6 includes a second fixing frame 61 and a third fixing seat 62. The second fixing frame 61 and the third fixing seat 62 are both fixedly installed on the base 1. A hydraulic rod 63 (hydraulic cylinder) is fixedly installed on the second fixing frame 61. The lower end of the output end of the hydraulic rod 63 is fixedly connected to the upper stamping die 65. A lower stamping die 66 is provided directly below the upper stamping die 65. The lower stamping die 66 is fixedly connected to the third fixing seat 62.

[0046] In this embodiment, the second fixing frame 61 has an inverted L-shaped structure. The bottom of the second fixing frame 61 is fixedly connected to the base 1. A set of sliding rods 64 is slidably connected to each of the four corners of the top of the second fixing frame 61. The lower ends of the four sets of sliding rods 64 are fixedly connected to the upper end of the stamping upper die 65. The sliding connection of the four sets of sliding rods 64 not only ensures the stability of the stamping upper die 65 when it moves up and down, but also ensures the stamping accuracy of the die.

[0047] like Figure 9 As shown, in order to automatically move and pick up the stamping plate 10 and the product blank from the positioning component 5 and the stamping component 6, the picking component 7 includes an electric guide rail 71, which is fixedly connected to the base 1. The electric guide rail 71 can be arranged on the base 1 in the front-back direction. An electric lifting platform 72 is provided on the electric guide rail 71. A suction cup mounting bracket 73 with a pneumatic suction cup 76 is fixedly connected to the electric lifting platform 72. The pneumatic suction cup 76 is used to hold the stamping plate 10 and the product blank.

[0048] The suction cup mounting bracket 73 includes a fourth fixing base 74, on which two sets of suction cup connecting plates 75 are fixedly connected. The pneumatic suction cup 76 is fixedly connected to the suction cup connecting plates 75. In this embodiment, both the fourth fixing base 74 and the suction cup connecting plates 75 are of a straight-line structure, with the suction cup connecting plates 75 facing to the right. The two sets of suction cup connecting plates 75 are fixedly connected to the front and rear sides of the fourth fixing base 74, respectively, and the fourth fixing base 74 and the suction cup connecting plates 75 are fixedly connected to form a U-shaped structure.

[0049] In this embodiment, the electric lifting platform 72 is fixedly connected to the top of the slider of the electric guide rail 71, the suction cup mounting bracket 73 is fixedly connected to the top of the electric lifting platform 72, and two sets of suction cup connecting plates 75 and pneumatic suction cups 76 are arranged in parallel, and as shown... Figure 2 As shown, the center distance between the two sets of pneumatic suction cups 76 is the same as the center distance between the placement plate 52 and the stamping die 66. Therefore, when the front set of pneumatic suction cups 76 picks up the stamping plate 10, the rear set of pneumatic suction cups 76 can also pick up the product blank from the stamping die 66 at the same time.

[0050] like Figure 9 As shown, to facilitate electronic control of the operation of the first electric push rod 32, the second electric push rod 54, the hydraulic rod 63, the electric guide rail 71, the electric lifting platform 72, and the pneumatic suction cup 76, the stamping positioning mechanism also includes a control component 8. In this embodiment, the control component 8 includes a control box 81, which houses a signal receiver 82 and a central main board 83. The central main board 83 is equipped with a logic operation module 84 and a controller 85. The signal receiver 82 is connected to the contact sensor 53 to receive information transmitted by the contact sensor 53 in real time. The signal receiver 82 is electrically connected to the central main board 83 and sends the received information to the logic operation module 84 for analysis and calculation. Finally, the controller 85 controls the operation of each component through a pre-set program. The controller 85 is electrically connected to the first electric push rod 32, the second electric push rod 54, the hydraulic rod 63, the electric guide rail 71, the electric lifting platform 72, and the pneumatic suction cup 76.

[0051] The present invention also provides a stamping process method applicable to this stamping positioning mechanism, comprising the following steps: Step S1: Stack multiple sets of stamping plates 10 into the material box assembly 2. The bottom stamping plate 10 falls naturally into the push groove 34 of the push assembly 3. The push groove 34 limits the stamping plate 10, completing the feeding preparation. Step S2: Control the first electric push rod 32 of the pusher assembly 3 to push the pusher plate 33 towards the positioning assembly 5, and make the pusher plate 33 slide along the sliding groove 24; Step S3: When the stamping plate 10 moves to the outlet of the sliding groove 24, the push rod 45 contacts the stamping plate 10, assisting the stamping plate 10 to smoothly leave the sliding groove 24; after the stamping plate 10 has completely passed through the sliding groove 24, the lower end of the push rod 45 enters the gap between the chamfer 35 of the push groove 34 and the stamping plate 10. Step S4: Control the first electric push rod 32 to retract, drive the push plate 33 to move away from the positioning component 5, and push rod 45 to block the stamping plate 10 until the stamping plate 10 is pushed down onto the positioning component 5. Step S5: Control the second electric push rod 54 to drive the push plate 55 to move towards the stamping plate 10 until the stamping plate 10 is tightly attached to the positioning block 56 to achieve clamping and positioning. Step S6: Start the automatic pick-up component 7, and drive the electric guide rail 71 to move the electric lifting platform 72 so that one set of pneumatic suction cups 76 is directly above the stamping plate 10 on the positioning component 5 and descends to absorb the stamping plate 10; at the same time, the other set of pneumatic suction cups 76 descends synchronously to absorb the stamped product blank. Step S7: Control the electric lifting platform 72 to rise, transfer the product blank to the outside, and at the same time place the previously positioned stamping plate 10 into the stamping assembly 6, and then automatically take the assembly 7 back to the initial position. Step S8: Control the hydraulic rod 63 to drive the upper stamping die 65 and the lower stamping die 66 to close, and stamp the stamping material plate 10 to form a product blank.

[0052] Specifically, the stamping process in this embodiment is as follows: Step S1: Stack multiple stamping plates 10 neatly into the stacking trough 23 inside the placement box 22. The bottom stamping plate 10 falls naturally into the sliding groove 24 and enters the pushing groove 34 at the top of the pushing plate 33, completing the loading preparation. Step S2: Start the control component 8 and work according to the working sequence and process set in advance by the internal controller 85. The controller 85 first sends a start signal to the first electric push rod 32 of the pusher component 3. After the first electric push rod 32 is energized, its output end pushes the pusher plate 33 to move backward (i.e. towards the positioning component 5) and slides along the sliding groove 24. The pusher groove 34 at the top of the pusher plate 33 limits the bottom set of stamping plates 10 to prevent the stamping plates 10 from shifting to the side. Step S3: When the stamping plate 10 moves to the outlet of the sliding groove 24, the push rod 45 contacts the stamping plate 10 under the elastic force of the torsion spring 44, assisting the stamping plate 10 to smoothly leave the sliding groove 24; after the stamping plate 10 has completely passed through the sliding groove 24, the torsion spring 44 drives the push rod 45 to reset, and the lower end of the push rod 45 enters the gap between the chamfer 35 and the stamping plate 10; Step S4: The first electric push rod 32 retracts, driving the push plate 33 to move forward (i.e. away from the positioning component 5). The push rod 45 blocks the stamping plate 10 to prevent it from moving forward until the stamping plate 10 is pushed onto the placement plate 52 of the positioning component 5. Step S5: After the contact sensor 53 in the middle of the placement plate 52 detects the stamping plate 10, it immediately transmits a signal to the signal receiver 82. The signal receiver 82 receives the signal and transmits it to the central main board 83. After analysis by the logic operation module 84, the controller 85 sends an action command to the second electric push rod 54 of the positioning component 5. After the second electric push rod 54 is energized, it drives the push plate 55 to move towards the stamping plate 10, pushing the stamping plate 10 towards the two symmetrical positioning blocks 56 until the stamping plate 10 and the positioning blocks 56 are tightly fitted together, thus achieving clamping and positioning. Step S6: The controller 85 controls the electric guide rail 71 to be powered on and start, driving the electric lifting platform 72 to move, so that one set of pneumatic suction cups 76 is directly above the stamping plate 10 on the positioning component 5. Then the electric lifting platform 72 descends, so that the pneumatic suction cups 76 are in contact with the stamping plate 10. After the pneumatic suction cup 26 is powered on, it generates negative pressure and adsorbs the stamping plate 10. At the same time, the other set of pneumatic suction cups 76 is directly above the stamping die 66 and descends synchronously to adsorb the stamped product blank. Step S7: The electric lifting platform 72 rises and transfers the product blank to the external storage box through the electric guide rail 71. At the same time, the previously positioned stamping plate 10 is placed inside the stamping die 66. Then, the component 7 is automatically retrieved and reset to the initial position to avoid interference with the stamping component 6. Step S8: The hydraulic rod 63 is energized and starts, outputting downward pressure to drive the upper stamping die 65 to descend vertically along the sliding trajectory of the four sets of sliding rods 64. The sliding rods 64 ensure that the upper stamping die 65 does not deviate and is always aligned with the lower stamping die 66 below. When the upper stamping die 65 and the lower stamping die 66 are completely closed, the stamping material plate 10 can be stamped to form a product blank. Then the hydraulic rod 63 maintains the set pressure and drives the upper stamping die 65 to return to its original position, completing a single stamping operation. This completes one workflow, which is then repeated in a cycle.
