Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment, and in particular to a stamping device for processing automotive reinforcing pads. Background Technology

[0002] Stamping is a forming process that uses a press and a die to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size. With the development of society, people's demand for stamping is increasing, including the stamping of automotive parts.

[0003] In existing technologies, the stamping of automotive reinforcement pads is generally carried out by driving equipment to separate or close two dies to stamp the automotive reinforcement pads. However, there are various types of stamping operations for automotive reinforcement pads, and different sizes of stamping dies are required for different types of stamping operations. Existing stamping devices can only fix stamping dies of one size. When fixing stamping dies of different sizes, gaps often occur due to incompatibility, resulting in unstable installation. Consequently, the dies may shift due to force during the stamping process, leading to a decrease in the quality and precision of the stamping operation. Therefore, a stamping device for processing automotive reinforcement pads is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1This utility model provides an embodiment of a stamping device for processing automotive reinforcing pads, including a base 1. The base 1 can improve the stability of the equipment during operation, thereby improving the processing quality. A support frame 2 is fixedly connected to the top of the base 1, and a stamping mechanism is provided at the bottom of the support frame 2. The stamping mechanism includes an electric cylinder 3, which is fixedly installed on the top of the support frame 2. A worktable 8 is fixedly connected to the top of the base 1 to facilitate stamping operations. A limit mechanism is provided inside the worktable 8, which includes a stepper motor 12. The stepper motor 12 can precisely control the rotation angle of its output shaft, making it easy to adjust the rotation angle of the stepper motor 12. It can adapt to the installation of lower molds 11 of different sizes, with good adaptability. The stepper motor 12 is fixedly installed on the back of the worktable 8, and a controller 20 is fixedly connected to the front of the base 1 to facilitate the control of the working state of the stepper motor 12 and the electric cylinder 3.

[0032] Reference Figure 1 , Figure 2 The stamping mechanism also includes a vertically arranged transmission rod 4, which is fixedly installed at the bottom of the output shaft of the electric cylinder 3. A fixing block 5 is fixedly connected to the bottom of the transmission rod 4 to facilitate the installation of the upper die 6. The stamping mechanism also includes an upper die 6 for stamping automotive reinforcing pads. The upper die 6 is detachably connected by fastening bolts 7 and fixing block 5 to facilitate the replacement of the upper die 6.

[0033] Reference Figures 3-4 The limiting mechanism also includes a positioning rod 10. The top of the worktable 8 is provided with an installation groove 9. The positioning rod 10 is fixedly installed at the bottom of the inner wall of the installation groove 9. The number of positioning rods 10 is set to multiple, and the multiple positioning rods 10 are symmetrically arranged at the bottom of the inner wall of the installation groove 9. The positioning rod 10 is set as a vertical cylinder. The limiting mechanism also includes a lower mold 11 that cooperates with the upper mold 6 to facilitate the stamping of the automotive reinforcement pad. The lower mold 11 is inserted into the outer wall of the positioning rod 10, and the bottom of the lower mold 11 contacts the bottom of the inner wall of the installation groove 9. By setting the positioning rod 10, the lower mold 11 can be positioned when installed in the installation groove 9, so that the lower mold 11 can be accurately installed directly below the stamping mechanism, improving the installation accuracy of the lower mold 11 and thus improving the processing quality of the punching.

[0034] Reference Figures 3-5The limiting mechanism also includes a worm gear 13 and a worm wheel 14. The worm gear 13 is fixedly installed on the front side of the output shaft of the stepper motor 12. The worm gear 13 and the worm wheel 14 mesh. Due to the self-locking characteristic of the transmission between the worm wheel 14 and the worm gear 13, the positioning and clamping effect is relatively stable after the stepper motor 12 stops rotating when the lower mold 11 is bidirectionally limited, ensuring the machining accuracy. The limiting mechanism also includes a bidirectional threaded rod 15. The circumferential surface of the bidirectional threaded rod 15 is provided with two sections of threaded grooves with opposite directions of rotation. The worm wheel 14 is fixedly installed on the circumferential surface of the bidirectional threaded rod 15. The bidirectional threaded rod 15 is rotatably installed on the inner wall of the worktable 8. The limiting mechanism also includes a nut block 16 and a connecting rod 17. The nut block 16 slides on the circumferential surface of the bidirectional threaded rod 15. The number of nut blocks 16 is set to two sets, and the two sets of nut blocks 16 slide on thread grooves with different helical directions. When the bidirectional threaded rod 15 rotates, the two sets of nut blocks 16 move away from each other or move closer to each other. One end of the connecting rod 17 is hinged to the surface of the nut block 16, and the other end of the connecting rod 17 is hinged to a limiting plate 18. The number of limiting plates 18 is set to two sets. On the side of the two sets of limiting plates 18 that are close to each other, there is a fixed anti-slip rubber block 19 to improve the friction force, which further improves the stability of clamping and fixing.

[0035] Working principle: In use, first install the lower mold 11, align the lower mold 11 with the positioning rod 10 and press the lower mold 11 down so that the positioning rod 10 is inserted into the inner wall of the lower mold 11, completing the initial installation. Start the power of the stepper motor 12 through the controller 20. The stepper motor 12 drives the worm gear 13 to rotate. The rotation of the worm gear 13 drives the worm wheel 14 to rotate. The rotation of the worm wheel 14 drives the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 causes the two sets of nut blocks 16 to move closer to each other. Then, the connecting rod 17 pulls the two sets of limiting plates 18 to move and move closer to each other. When the two sets of limiting plates 18 move closer to each other and press the front and rear sides of the lower mold 11 together, stop the operation of the stepper motor 12 and apply a pre-tightening force to the lower mold 11, thereby firmly fixing the lower mold 11 inside the mounting groove 9. Since the rotation angle of the stepper motor 12 is adjustable, the displacement distance of the limiting plate 18 can be precisely controlled, and the lower mold 11 of different sizes can be positioned and fixed.

[0036] When it is necessary to replace the upper mold 6 that matches the lower mold 11, the upper mold 6 is removed from the surface of the fixing block 5 by loosening the fastening bolts 7. Then, the upper mold 6 that matches the lower mold 11 is aligned with the fixing block 5 and pressed upward to install the upper mold 6 on the surface of the fixing block 5. Then, the upper mold 6 is securely installed on the surface of the fixing block 5 by tightening the fastening bolts 7, which improves the stability of the upper mold 6 during stamping and thus ensures the quality and precision of stamping the automotive reinforcing pad.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
