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 equipment. 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 equipment 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 that result in large height differences, higher requirements are placed on the closing height of the stamping equipment in order to accommodate the workpiece and the necessary mold structure.

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

[0006] For manufacturing enterprises, this constitutes a huge pressure on fixed asset investment, which 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 equipment for automobile 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: An automotive parts stamping apparatus has mutually orthogonal first, second, and vertical directions; the stamping apparatus includes: A stamping machine, which has a stamping working area; Stamping dies, which include: The lower die is placed on the worktable of the stamping machine; The upper die is located within the stamping working area, fixed to the output end of the stamping machine, and positioned above the lower die; An extension drive is fixed relative to the press, its driving direction is parallel to the first direction, and its output end is connected to the lower die. It is used to drive the lower die to move along the first direction, so that the lower die extends out of the stamping working area.

[0009] 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 worktable of the stamping machine and extend along a first direction; An extendable guide wheel is rotatably mounted on the lower mold and cooperates with the extendable guide rail to guide the lower mold.

[0010] As a further improvement to the above technical solution, the lower mold 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.

[0011] As a further improvement to the above technical solution, the end of the extension drive member is fixed with a first connecting part, and the lower mold is fixed with a second connecting part. The first connecting part and the second connecting part are inserted into each other, and the first connecting part and the second connecting part can slide relative to each other in the vertical direction.

[0012] As a further improvement to the above technical solution, the lifting drive component is a hydraulic linear drive device.

[0013] As a further improvement to the above technical solution, the extension drive 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 mold; The limit drive component is embedded and fixed to the worktable of the stamping machine, and its driving direction is parallel to the up and down direction. A limiting component is provided corresponding to the limiting slot. It is used to insert into the limiting slot to limit the lower die. It is fixed to the output end of the limiting drive component and is embedded in the worktable of the stamping machine.

[0015] As a further improvement to the above technical solution, multiple limiting mechanisms are provided, and the multiple limiting mechanisms are evenly arranged.

[0016] As a further improvement to the above technical solution, the upper edge of the limiting member and the groove 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 invention are as follows: In the prior art, after the workpiece is stamped, the robotic arm extends into the stamping working area to pick up the workpiece and lift it a certain distance before it can be moved laterally to remove the workpiece from the stamping working area. This places high demands on the closing height of the stamping equipment. In this solution, after the workpiece is stamped, the extending drive component drives the lower die to extend out of the stamping working area. With this configuration, the robotic arm can remove the workpiece from outside the stamping working area, effectively reducing the closing height requirement of the stamping equipment, thereby reducing the production cost of the stamping equipment and the cost of purchasing equipment for the factory.

[0026] The stamping equipment includes: a stamping press 100, a stamping die 200, an extension drive component 300, an extension guide assembly 400, and a limit mechanism 500.

[0027] The stamping machine 100 is a conventional hydraulic stamping equipment. The specific structure of the stamping machine 100 will not be described in detail here. The stamping machine 100 is equipped with an output end.

[0028] The stamping machine 100 is equipped with a stamping working area.

[0029] The stamping die 200 includes: a lower die 210 and an upper die 220.

[0030] The lower die 210 is placed on the worktable of the stamping machine. A second connecting part 320 is fixed to the side wall of the lower die 210.

[0031] Specifically, in this embodiment, the lower mold 210 includes: a main mold body 211, a lifting structure 212, and a lifting drive component 213.

[0032] The number of lifting structures 212 is set to two. The two lifting structures 212 are respectively set on both sides of the main mold body 211 in the second direction. The lifting structures 212 and the main mold body 211 slide and connect in the vertical direction.

[0033] The number of lifting drive components 213 is set to two, and the two lifting drive components 213 are respectively set to correspond to the two lifting structures 212. The lifting drive components 213 are set between the main mold body 211 and the lifting structure 212. The lifting drive components 213 are fixedly installed on the main mold body 211, and the output end of the lifting drive component 213 is fixedly connected to the lifting structure 212. Specifically, in this embodiment, the lifting drive component 213 is set as a hydraulic linear drive device.

[0034] The lifting drive component 213 is used to drive the lifting structure 212 to move up and down, so that the lower end face of the main mold body 211 is separated from or in contact with the worktable of the stamping machine, so as to facilitate the movement and fixation of the lower mold 210.

[0035] The upper die 220 is fixedly installed at the output end of the stamping machine 100. The upper die 220 is located in the stamping working area and is positioned above the lower die 210. When stamping a workpiece, the stamping machine 100 drives the upper die 220 to move downward, bringing the upper die 220 closer to the lower die 210 until the two are closed, thus completing the stamping process.

[0036] Specifically, in this embodiment, the extension drive 300 is configured as a conventional hydraulic linear drive device, and the driving direction of the extension drive 300 is parallel to the first direction.

[0037] The extension drive 300 is fixedly connected to the factory floor via a connecting frame, thereby fixing the extension drive 300 relative to the press. The output end of the extension drive 300 is fixed with a first connecting part 310.

[0038] The first connecting part 310 and the second connecting part 320 are connected by insertion in the vertical direction, so that the first connecting part 310 and the second connecting part 320 can slide relative to each other in the vertical direction.

[0039] When the lower die 210 moves in the vertical direction, the second connecting part 320 moves vertically relative to the first connecting part 310. By setting the first connecting part 310 and the second connecting part 320, the connection between the lower die 210 and the extension drive 300 can be ensured, so that the extension drive 300 can normally drive the lower die 210 to move in the first direction, thereby allowing the lower die 210 to smoothly extend out of the stamping working area.

[0040] Specifically, the extendable guide assembly 400 includes: an extendable guide rail 410 and an extendable guide wheel 420.

[0041] The extendable guide rail 410 is fixedly installed on the worktable of the stamping machine 100 by screws. The portion of the extendable guide rail 410 extending out of the worktable of the stamping machine 100 is fixed to the factory floor by a frame. The extendable guide rail 410 extends along a first direction. Specifically, in this embodiment, the number of extendable guide rails 410 is set to two, and the two extendable guide rails 410 are arranged along a second direction.

[0042] The extendable guide wheel 420 is rotatably mounted on the lifting structure 212. The extendable guide wheel 420 cooperates with the extendable guide rail 410 to restrict the movement direction of the lower mold 210.

[0043] Specifically, in this embodiment, the cross-section of the extending guide rail 410 is triangular, and the outer periphery of the extending guide wheel 420 is provided with a guide groove. The cross-section of the guide groove is triangular, and the guide groove engages with the extending guide rail 410 to restrict the position of the extending guide wheel 420 in the second direction.

[0044] Specifically, the limiting mechanism 500 includes: a limiting mounting shell 510, a limiting slot 520, a limiting drive component 530, and a limiting component 540.

[0045] The limiting slot 520 is located at the lower end of the main mold body 211 of the lower mold 210.

[0046] The limiting mounting shell 510 is embedded in the worktable of the stamping machine.

[0047] The limit drive component 530 is fixedly installed inside the limit mounting shell 510, so that the height of the limit drive component 530 is lower than the height of the worktable of the stamping machine, and the driving direction of the limit drive component 530 is parallel to the up and down direction.

[0048] The limiting member 540 is fixedly installed at the output end of the limiting drive member 530 and is installed inside the limiting mounting shell 510. The position of the limiting member 540 corresponds to the position of the limiting slot 520. The limiting member 540 is used to plug into the limiting slot 520 to limit the lower die 210, so as to prevent the lower die 210 from being displaced in the first direction during the stamping process, thereby ensuring the quality of the final processed product and protecting the upper die 220 and the lower die 210.

[0049] Specifically, in this embodiment, the number of limiting mechanisms 500 is set to two, and the two limiting mechanisms 500 are arranged at intervals along the second direction. In other embodiments, the number of limiting mechanisms 500 may also be set to three, four, or other numbers. Those skilled in the art can select the number of limiting mechanisms 500 according to actual needs.

[0050] Specifically, in this embodiment, chamfers are provided at the upper edge of the limiting member 540 and at the opening of the limiting slot 520. 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 540 can be more easily inserted into the limiting slot 520.

[0051] Specifically, in this embodiment, the limiting member 540 has a conical structure, and the limiting slot 520 matches the limiting member 540. By setting the limiting member 540 to a conical structure and matching the limiting slot 520 with the limiting member 540, the main mold body 211 can be repositioned when it descends, so as to ensure the accuracy of the final placement position of the main mold body 211 and thus ensure the quality of the workpiece.

[0052] 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.
