Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a stamping die for rapid positioning in automotive parts processing. Background Technology
[0002] In the field of stamping processing of automotive parts, with the rapid development of the automotive industry and the continuous improvement of market demand for automotive quality and personalization, higher requirements have been placed on the processing accuracy, production efficiency and versatility of molds. However, existing stamping dies have many problems in practical applications and are difficult to meet current production needs.
[0003] On the one hand, existing stamping dies have significant deficiencies in the automatic correction function of parts. In actual production, parts inevitably experience positional deviations or tilting during placement. If these deviations are not corrected in time, the parts will not be able to accurately enter the die cavity, affecting stamping quality and even damaging the die. However, most stamping dies currently lack an effective automatic correction mechanism and cannot detect and adjust the initial position of parts, relying solely on subsequent manual intervention or rework. This undoubtedly increases production costs and reduces production efficiency. On the other hand, traditional positioning components are mostly fixed, and when different specifications of products need to be produced, the entire die often needs to be replaced.
[0004] Therefore, those skilled in the art provide a stamping die for rapid positioning in the processing of automotive parts to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the shortcomings of traditional automotive parts processing stamping dies, such as the lack of correction devices and low adaptability of positioning components, this invention provides a stamping die for rapid positioning in automotive parts processing, employing the following technical solution:
[0006] A stamping die for rapid positioning in automotive parts processing includes a base plate, a lower die fixedly connected to the top of the base plate, a correction mechanism fixedly connected to the bottom of the base plate, a positioning mechanism movably connected to the inner cavity of the lower die, and a stamping mechanism disposed on the top of the lower die. The correction mechanism includes a motor, the bottom of which is fixedly connected to the base plate. A gear is fixedly connected to the output end of the motor, a gear plate meshing with one side of the gear, a fixed block rotatably connected to the inner side of the gear plate, the top of which is fixedly connected to the base plate, a correction rod slidably connected to the inner cavity of the fixed block, a slot being formed on the surface of the gear plate, a sliding pin fixedly connected to the top of the correction rod, the top of which is slidably connected to the slot, and a correction plate fixedly connected to the top of the correction rod, with both sides of the bottom of the correction plate slidably connected to the base plate.
[0007] Optionally, the positioning mechanism includes a lead screw, one side of which is movably connected to the lower mold via a bearing, and the other side of which passes through the inner cavity of the lower mold and extends to the surface of the lower mold. A connecting block is threaded onto the surface of the lead screw, and slide rods are slidably connected to the bottom of both sides of the connecting block. Both sides of the slide rods are fixedly connected to the lower mold, and positioning pins are fixedly connected to the top of both sides of the connecting block.
[0008] Optionally, the stamping mechanism includes a fixed frame, the bottom sides of the fixed frame are fixedly connected to the base plate, a hydraulic cylinder is fixedly connected to the top of the fixed frame, a hydraulic rod is slidably connected to the inner cavity of the hydraulic cylinder, an upper die is fixedly connected to the bottom of the hydraulic rod, and both sides of the upper die are slidably connected to the fixed frame.
[0009] Optionally, the top of the base plate is provided with a movable groove, and a limit rod is slidably connected to the inner cavity of the movable groove. The top of the limit rod is fixedly connected to the correction plate.
[0010] Optionally, a knob is provided on one side of the lower mold, and one side of the knob is fixedly connected to the lead screw.

[0013] Optionally, a scale groove is provided on one side of the limiting groove, and an indicator is provided on the top of the scale groove. One side of the indicator is fixedly connected to the connecting block.
[0014] In summary, this utility model has the following beneficial effects:
[0015] 1. The correction mechanism of this utility model uses a motor-driven gear and a gear plate to mesh and transmit power, which converts the rotational motion of the motor into the horizontal movement of the correction rod and the correction plate. This realizes the automatic correction of the placement deviation of the parts. Compared with the traditional manual adjustment or molds without automatic correction function, this mechanism can quickly respond to the position deviation of the parts without manual intervention, which greatly shortens the positioning preparation time, significantly improves the degree of production automation and the overall processing cycle, and meets the high efficiency requirements of large-scale production of automotive parts.
[0016] 2. The positioning mechanism of this utility model utilizes the threaded transmission between the lead screw and the connecting block to precisely convert the rotational motion of the lead screw into the linear movement of the connecting block. Combined with the guiding effect of the sliding rods on both sides, the positioning pin can move along a precise trajectory. In the process of processing automotive parts, whether it is a complex irregular-shaped part or a precision part with extremely high dimensional accuracy requirements, the positioning pin can accurately fit the positioning reference of the part, eliminate the processing error caused by position deviation, thereby ensuring that the dimensional accuracy of the stamped part is highly consistent with the design standard, and effectively improve the product qualification rate.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] Example 1:
[0026] Please refer to Figure 1-5A stamping die for rapid positioning in automotive parts processing includes a base plate 1, a lower die 2 fixedly connected to the top of the base plate 1, a correction mechanism 3 fixedly connected to the bottom of the base plate 1, a positioning mechanism 4 movably connected to the inner cavity of the lower die 2, and a stamping mechanism 5 provided on the top of the lower die 2. The correction mechanism 3 includes a motor 301, the bottom of the motor 301 fixedly connected to the base plate 1, a gear 302 fixedly connected to the output end of the motor 301, a gear disk 303 meshing on one side of the gear 302, a fixing block 304 rotatably connected to the inner side of the gear disk 303, the top of the fixing block 304 fixedly connected to the base plate 1, a correction rod 305 slidably connected to the inner cavity of the fixing block 304, a slot 306 opened on the surface of the gear disk 303, a sliding pin 307 fixedly connected to the top of the correction rod 305, the top of the sliding pin 307 slidably connected to the slot 306, and a correction plate 308 fixedly connected to the top of the correction rod 305, with both sides of the bottom of the correction plate 308 slidably connected to the base plate 1.
[0027] In this embodiment: A control panel is fixedly connected to one side of the top of the base plate 1 for controlling the entire device. A photoelectric sensor is set on the top of the control panel. One side of the photoelectric sensor is fixedly connected to the lower mold 2 for detecting whether the parts are in the correct position. If the parts are detected to be on the top of the lower mold 2, the information is transmitted to the control system and the motor 301 is started. The whole process does not require manual intervention, which greatly improves production efficiency. A rubber pad is fixedly connected to the surface of the correction plate 308 to prevent damage to the surface of the parts during the correction process. There are four correction plates 308 and four correction rods 305, which are evenly distributed around the lower mold 2, and can correct the position of the parts from four directions at the same time.
[0028] Example 2:
[0029] Reference Figure 1-5The positioning mechanism 4 includes a lead screw 401. One side of the lead screw 401 is movably connected to the lower mold 2 via a bearing, and the other side of the lead screw 401 passes through the inner cavity of the lower mold 2 and extends to the surface of the lower mold 2. A connecting block 402 is threaded onto the surface of the lead screw 401. Sliding rods 403 are slidably connected to the bottom of both sides of the connecting block 402. Both sides of the sliding rods 403 are fixedly connected to the lower mold 2. Positioning pins 404 are fixedly connected to the top of both sides of the connecting block 402. The stamping mechanism 5 includes a fixed frame 501. The bottom of both sides of the fixed frame 501 is fixedly connected to the base plate 1. A hydraulic cylinder 502 is fixedly connected to the top of the fixed frame 501. A hydraulic rod 503 is slidably connected to the inner cavity of the hydraulic cylinder 502. The bottom of the hydraulic rod 503 is fixedly connected to... The upper mold 504 is slidably connected to the fixed frame 501 on both sides. The bottom plate 1 has a movable groove 6 on the top. The inner cavity of the movable groove 6 is slidably connected to the limit rod 7. The top of the limit rod 7 is fixedly connected to the correction plate 308. The lower mold 2 has a knob 8 on one side. The knob 8 is fixedly connected to the lead screw 401 on one side. The upper mold 504 has guide rods 9 fixedly connected to both sides. The surface of the guide rods 9 is slidably connected to the fixed frame 501. The lower mold 2 has limit grooves 10 on both sides. The connecting block 402 is slidably connected to the limit grooves 10 on both sides. The limit groove 10 has a scale groove 11 on one side. The top of the scale groove 11 has an indicator 12. The indicator 12 is fixedly connected to the connecting block 402 on one side.
[0030] In this embodiment: there are four positioning pins 404, symmetrically distributed at the four corners of the lower mold 2, which can accurately limit the movement and rotation of the parts in the horizontal and vertical directions. The lead screw 401 has threads on both sides, which can make the connecting blocks 402 on both sides move inward at the same time, greatly shortening the positioning time. The fixed frame 501 is located on one side of the two correction plates 308, which can improve the stability of the hydraulic cylinder 502 during operation. The setting of the movable groove 6 and the limit rod 7 can limit the range of motion and operation mode of the correction plate 308. The operator can adjust the position of the positioning pins 404 by rotating the knob 8, which improves the convenience of the device. There are two guide rods 9, which provide precise guidance for the upper mold 504. There are two limit grooves 10, which can limit the range of motion of the connecting block 402. The combination of the scale groove 11 and the indicator 12 makes the positioning process no longer dependent on experience judgment, and improves the positioning accuracy from the traditional approximate range control to precise numerical control.
[0031] The implementation principle of this utility model is as follows: In use, the position of the positioning pin 404 is first adjusted according to the specifications of the parts. By rotating the knob 8, the knob 8 drives the lead screw 401 to rotate. The lead screw 401 drives the connecting blocks 402 on both sides to move along the slide bar 403. The positioning pin 404 moves with the connecting blocks 402. After the adjustment is completed, the parts are placed on the top of the lower mold 2. After the photoelectric sensor detects that the parts are not correctly placed on the lower mold 2, it will transmit this information to the control system, start the motor 301, drive the gear 302 to rotate, drive the gear disk 303 to rotate, and drive the groove. When 306 rotates, the sliding pin 307 gradually moves towards the center of the lower mold 2 through the slot 306. The correcting rod 305 moves along the inner cavity of the fixed block 304 following the sliding pin 307. The correcting plate 308 moves along the correcting rod 305 and pushes the part towards the center of the lower mold 2, so that it enters the inner cavity of the lower mold 2 and engages with the positioning pin 404. Then, the motor 301 reverses and drives the correcting plate 308 to reset, preparing for the next correction. After the part enters the inner cavity of the upper mold 504, the hydraulic cylinder 502 pushes the hydraulic rod 503. The hydraulic rod 503 presses down on the upper mold 504, and the upper mold 504 enters the inner cavity of the lower mold 2 and stamps the part.
[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
