Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing mold technology, and in particular to an automotive parts stamping mold. Background Technology

[0002] With the continuous improvement of industrial manufacturing capabilities, the application of large stamped parts in the production of automotive body panels is becoming increasingly widespread. The production of such parts generally relies on large stamping presses with high tonnage and wide worktables.

[0003] Currently, a mature automated production line typically includes a stamping machine, a robotic arm for loading and unloading, and a conveying device. After the workpiece is shaped in the mold, the robotic arm extends into the working area of ​​the equipment and uses its end effector (usually a vacuum chuck or an electromagnetic chuck) to pick up and transfer the workpiece.

[0004] However, when producing workpieces with significant height differences, such as workpieces with large thickness or complex shapes resulting in large height differences, higher requirements are placed on the closing height of the stamping press in order to accommodate the workpiece and the necessary mold structure.

[0005] As is well known, the manufacturing cost of a stamping press is positively correlated with its closing height. A higher closing height means that the press's frame, slide, worktable, and even drive system need to be reinforced, leading to a significant increase in the purchase price of the press.

[0006] When manufacturers need to produce workpieces with significant height differences, if the closing height of the existing stamping press does not meet the requirements, the manufacturers need to purchase a new stamping press. For manufacturing enterprises, this constitutes a huge fixed asset investment pressure and seriously affects the control of production costs and economic benefits. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a stamping die for automotive parts, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0008] The solution to the technical problem of this utility model is: A stamping die for automotive parts has mutually orthogonal first direction, second direction, and vertical direction; the stamping die has a closing direction, which is inclined relative to the first direction and the vertical direction, and includes: A stamping upper die, which has an upper die parting surface; the upper die parting surface is perpendicular to the closing direction; A stamping die has a parting surface, which is perpendicular to the closing direction; The misalignment driving mechanism includes: A power connection structure is used to drive the upper stamping die to move up and down. It is installed on the upper end of the upper stamping die and connected to the output end of the stamping machine. It can move relative to the upper stamping die in a first direction. The upper die guide structure is used to guide the upper stamping die so that during the upward movement of the upper stamping die, it moves away from the lower stamping die along a first direction.

[0009] As a further improvement to the above technical solution, the misalignment driving mechanism further includes: The lower die drive structure has its output end connected to the lower die of stamping, and is used to drive the lower die of stamping to move along a first direction.

[0010] As a further improvement to the above technical solution, the lower mold drive structure is a hydraulic linear drive device.

[0011] As a further improvement to the above technical solution, it also includes: an extension guide assembly, the extension guide assembly comprising: Extending guide rails are fixed to the factory floor and extend along a first direction; An extendable guide wheel is rotatably mounted on the lower stamping die and cooperates with the extendable guide rail to guide the lower stamping die.

[0012] As a further improvement to the above technical solution, the stamping die includes: Main model body; A lifting structure is slidably connected to the main mold body in the vertical direction; the extending guide wheel is rotatably mounted on the lifting structure. A lifting drive component is disposed between the main mold body and the lifting structure, and is used to drive the lifting structure to move up and down relative to the main mold body so that the extension guide wheel disengages from or engages with the extension guide rail.

[0013] As a further improvement to the above technical solution, the lifting drive component is a hydraulic linear drive device.

[0014] As a further improvement to the above technical solution, a limiting mechanism is also included, the limiting mechanism comprising: A limiting slot is provided in the lower stamping die; A limiting drive component is fixedly disposed on the side of the lower stamping die, and its driving direction is parallel to the second direction; A limiting component is provided corresponding to the limiting slot. It is used to insert into the limiting slot to limit the lower mold. It is fixed to the output end of the limiting drive component.

[0015] As a further improvement to the above technical solution, at least two limiting mechanisms are provided, and at least two limiting mechanisms are arranged on both sides of the stamping die in the second direction.

[0016] As a further improvement to the above technical solution, the edge of the limiting member near the limiting slot and the opening of the limiting slot are chamfered.

[0017] As a further improvement to the above technical solution, the limiting member has a conical structure, and the limiting slot matches the limiting member.

[0018] The beneficial effects of this utility model are as follows: when the upper die is driven upward by the press, the upper die moves away from the lower die along the first direction by the guide structure of the upper die, so that the distance between the parting surface of the upper die and the parting surface of the lower die is further increased. This facilitates the insertion of the actuator of the robotic arm between the upper die and the lower die, and provides more space for the actuator of the robotic arm to move, so that the workpiece after stamping can be taken out.

[0019] Compared to existing technologies that involve direct vertical movement, this solution reduces the required closing height of the stamping press. This allows manufacturers to produce workpieces with significant height differences without needing to replace the press with one that has a larger closing height, thus reducing their capital investment and ensuring their economic benefits.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0025] Reference Figures 1 to 3 A stamping die for automotive parts has a first direction, a second direction, and a vertical direction, which are orthogonally arranged. Referring to the illustration, the first direction is parallel to the X-axis, the second direction is parallel to the Y-axis, and the vertical direction is parallel to the Z-axis.

[0026] The stamping die has a closing direction, which is inclined relative to the first direction and the up and down direction.

[0027] The stamping die includes: a die frame 110, an upper stamping die 120, a lower stamping die 130, a misalignment drive mechanism, and an extension guide assembly 300.

[0028] The mold frame 110 is fixedly placed on the worktable of the stamping machine.

[0029] The lower stamping die 130 is mounted on the die frame 110. Specifically, in this embodiment, the lower stamping die 130 includes: a main die body 131, a lifting structure 133, and a lifting drive component 132.

[0030] The main mold body 131 is provided with a lower mold parting surface, which is perpendicular to the closing direction. Specifically, the main mold body 131 should be provided with a limiting structure to prevent the sheet metal from slipping. Those skilled in the art can adjust the position of the limiting structure according to actual needs, ensuring that the limiting structure is located below the sheet metal.

[0031] The number of lifting structures 133 is set to two. The two lifting structures 133 are respectively set on both sides of the main mold body 131 in the second direction. The lifting structures 133 and the main mold body 131 slide and connect in the vertical direction.

[0032] The number of lifting drive components 132 is set to two, and the two lifting drive components 132 are respectively set to correspond to the two lifting structures 133. The lifting drive components 132 are set between the main mold body 131 and the lifting structure 133. The cylinder of the lifting drive component 132 is fixedly installed on the main mold body 131, and the output end of the lifting drive component 132 is fixedly connected to the lifting structure 133. Specifically, in this embodiment, the lifting drive component 132 is set as a hydraulic linear drive device.

[0033] The lifting drive component 132 is used to drive the main mold body 131 to move up and down, so that the lower end face of the main mold body 131 is separated from or in contact with the worktable of the stamping machine, so as to facilitate the movement and fixation of the stamping lower die 130.

[0034] The upper stamping die 120 is positioned above the lower stamping die 130, and the upper stamping die 120 is slidably connected to the die frame 110. When stamping a workpiece, the stamping machine drives the upper stamping die 120 to move in the closing direction, bringing the upper stamping die 120 closer to the lower stamping die 130 until the two close together to complete the stamping process.

[0035] The upper stamping die 120 is provided with an upper die parting surface, which is perpendicular to the closing direction.

[0036] Specifically, a support structure 500 is provided between the stamping upper die 120 and the die frame 110. The number of support structures 500 is set to two, and the two support structures 500 are respectively provided on both sides of the stamping upper die 120 in the second direction.

[0037] The support structure 500 includes: a support slide 510, a first guide rail 520, and upper and lower guide rails 530. The upper and lower guide rails 530 extend in the vertical direction, and there are two upper and lower guide rails 530 arranged at intervals along a first direction. The upper and lower guide rails 530 are fixedly installed on the mold frame 110. The support slide 510 is slidably connected to the upper and lower guide rails 530, allowing the support slide 510 to move in the vertical direction. There is one first guide rail 520, which extends in the first direction, and the side wall of the upper stamping die 120 is slidably connected to the first guide rail 520.

[0038] By setting up a support structure 500, the output end of the stamping press can be prevented from being biased to one side after the upper stamping die 120 moves along the first direction, thus protecting the stamping press.

[0039] The misalignment drive mechanism includes: a power connection structure 210 and an upper mold guide structure 220.

[0040] A power connection structure 210 is disposed between the upper stamping die 120 and the output end of the stamping machine. The power connection structure 210 is fixedly connected to the stamping machine. The lower end of the power connection structure 210 has an upper die sliding groove, and the upper end of the upper stamping die 120 has an upper die sliding strip. Both the upper die sliding strip and the upper die sliding groove extend along a first direction. The upper die sliding strip and the upper die sliding groove are slidably connected, allowing the upper stamping die 120 to slide relative to the power connection structure 210 along the first direction. When the output end of the stamping machine moves upward, the power connection structure 210 drives the upper stamping die 120 to move upward.

[0041] The upper mold guide structure 220 is fixedly installed on the mold frame 110. The upper mold guide structure 220 includes an upper mold guide track groove 221 and an upper mold guide connector 222. The upper mold guide track groove 221 is inclined. The upper end of the upper mold guide track groove 221 is further away from the lower stamping die 130 in the first direction than its lower end. The upper mold guide connector 222 is disposed in the upper mold guide track groove 221 and is slidably connected to the upper mold guide track groove 221.

[0042] Specifically, in this embodiment, the upper die guide connector 222 is configured as a roller structure, and the upper die guide connector 222 is rotatably connected to the upper stamping die 120. The upper die guide track groove 221 includes a first guide section 223 and a second guide section 224. The extension direction of the first guide section 223 is parallel to the closing direction, and the second guide section 224 is more inclined than the first guide section 223, so that after the upper die guide connector 222 enters the second guide section 224, it has the same displacement in the vertical direction, which can drive the upper stamping die 120 to move a greater distance in the first direction, so that the upper stamping die 120 can quickly move away from the lower stamping die 130.

[0043] When the upper stamping die 120 is driven upward by the stamping machine, it is guided by the upper die guide structure 220 to move away from the lower stamping die 130 along the first direction, so that the distance between the upper die parting surface and the lower die parting surface is further increased. This facilitates the insertion of the robotic arm's execution end between the upper stamping die 120 and the lower stamping die 130, and provides more space for the robotic arm's execution end to move, so that the stamped workpiece can be taken out.

[0044] Compared to existing technologies that involve direct vertical movement, this solution reduces the required closing height of the stamping press. This allows manufacturers to produce workpieces with significant height differences without needing to replace the press with one that has a larger closing height, thus reducing their capital investment and ensuring their economic benefits.

[0045] Specifically, in this embodiment, the misalignment drive mechanism further includes a lower die drive structure 230. The lower die drive structure 230 is configured as a hydraulic linear drive device. The lower die drive structure 230 is fixedly connected to the factory floor via a frame. The lower end of the lower die drive structure 230 is fixed to the factory floor via a frame. The driving direction of the lower die drive structure 230 is parallel to the first direction. The output end of the lower die drive structure 230 is fixed to the main die body 131. When the lower die drive structure 230 is working, it drives the lower die 130 to move away from the upper die 120 along the first direction, thereby increasing the distance between the lower die 130 and the upper die 120, so that the robotic arm can more easily remove the stamped workpiece.

[0046] Specifically, in this embodiment, a first connecting part 231 and a second connecting part 232 are provided between the lower mold drive structure 230 and the main mold body 131. The first connecting part 231 is fixedly installed at the output end of the lower mold drive structure 230, and the second connecting part 232 is fixedly installed at the main mold body 131.

[0047] The first connecting part 231 and the second connecting part 232 are connected by insertion in the vertical direction, so that the first connecting part 231 and the second connecting part 232 can slide relative to each other in the vertical direction.

[0048] When the main mold body 131 moves in the vertical direction, the second connecting part 232 moves vertically relative to the first connecting part 231. By setting the first connecting part 231 and the second connecting part 232, the connection between the lower mold and the extension drive can be ensured, so that the lower mold drive structure 230 can normally drive the stamping lower mold 130 to move in the first direction, thereby increasing the distance between the stamping lower mold 130 and the stamping upper mold 120.

[0049] The extension guide assembly 300 includes: an extension guide rail 310 and an extension guide wheel 320.

[0050] The extendable guide rail 310 is fixedly installed on the worktable of the stamping machine by screws and other components. The extendable guide rail 310 extends along a first direction, and the portion of the extendable guide rail 310 extending out of the worktable of the hydraulic press is fixed to the factory floor by a frame. Specifically, in this embodiment, the cross-section of the extendable guide rail 310 is set as a triangular cross-section structure.

[0051] The extension guide wheel 320 is rotatably mounted on the lifting structure 133. The extension guide wheel 320 has a guide groove, which is engaged with the extension guide rail 310. The extension guide wheel 320 and the extension guide rail 310 cooperate to guide the stamping die 130, so that the stamping die 130 moves in the first direction.

[0052] Specifically, the limiting mechanism 400 includes: a limiting slot 410, a limiting drive 420, and a limiting component 430.

[0053] The limiting drive component 420 is fixedly installed on the mold frame 110. The limiting drive component 420 is located on the side of the main mold body 131 in the second direction, and the driving direction of the limiting drive component 420 is parallel to the second direction.

[0054] The limiting component 430 is fixedly installed at the output end of the limiting drive component 420, and the limiting slot 410 is opened at the lower end of the main mold body 131 of the lower mold. The position of the limiting slot 410 corresponds to the position of the limiting component 430. The limiting component 430 is used to plug into the limiting slot 410 to limit the lower mold, so as to prevent displacement in the first direction during the stamping process of the lower mold, thereby ensuring the quality of the final processed product, and also protecting the upper stamping mold 120 and the lower stamping mold 130.

[0055] Specifically, in this embodiment, the number of limiting mechanisms 400 is set to two, and the two limiting mechanisms 400 are symmetrically arranged on both sides of the stamping die 130 along the second direction. In other embodiments, the number of limiting mechanisms 400 can also be set to three, four, or other numbers. Those skilled in the art can select the number of limiting mechanisms 400 according to actual needs.

[0056] Specifically, in this embodiment, chamfers are provided at the upper edge of the limiting member 430 and at the opening of the limiting slot 410. In this embodiment, the chamfer is set as a rounded corner. In other embodiments, the chamfer can also be set as an oblique chamfer. Those skilled in the art can select the specific structure of the chamfer according to actual needs. By setting the chamfer, the limiting member 430 can be more easily inserted into the limiting slot 410.

[0057] Specifically, in this embodiment, the limiting member 430 has a conical structure, and the limiting slot 410 matches the limiting member 430. By setting the limiting member 430 to a conical structure and matching the limiting slot 410 with the limiting member 430, the main mold body 131 can be repositioned when it descends, so as to ensure the positional accuracy of the main mold body 131 and thus ensure the quality of the workpiece.

[0058] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
