Description

Technical Field

[0001] This utility model relates to the field of automotive stamping die technology, and in particular to a hoisting device for automotive stamping dies. Background Technology

[0002] Automotive stamping dies are the core tooling for forming automotive parts, using a press to plastically deform sheet metal. They consist of working parts (punches and dies), guiding parts (guide pillars and guide bushings), and unloading devices. Based on the process, they are classified into blanking dies and punching dies. Blanking dies are used to obtain blanks, while punching dies process holes and slots. Their design requires precise calculation of the cutting edge clearance, and their manufacturing relies on high-precision machining technology.

[0003] In the automotive manufacturing industry, the efficient and safe lifting of stamping dies is crucial to the production process. Currently, traditional lifting equipment generally faces the problem of difficulty in accurately positioning the dies when lifting and transporting them. Due to the lack of effective positioning methods, the dies are prone to shaking during lifting, which not only increases the risk of surface damage and reduces their service life, but may also cause safety accidents such as equipment collisions. It also affects the accuracy and efficiency of subsequent die installation. Therefore, this utility model proposes a lifting device for automotive stamping dies to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a hoisting device for automotive stamping dies, which solves the problem in the prior art where it is inconvenient to position the die during hoisting and transportation, making the die prone to shaking during transportation and thus reducing the stability of the device during use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a hoisting device for automotive stamping dies, comprising a base plate, rollers installed at the four corners of the bottom end of the base plate, a controller installed at the front end of one side above the base plate, a support block installed on one side above the base plate, an mounting frame installed at the top of the support block, a lifting device body installed at one end of the mounting frame, a hook installed below the lifting device body via a lifting rope, a rotating mechanism provided below the support block, and a positioning mechanism provided on one side above the base plate;

[0006] The positioning mechanism includes a first servo motor, a threaded rod, a threaded sleeve, a mounting plate, a cylinder, a positioning frame, and a limiting structure. The first servo motor is mounted on the front end of the base plate, and the threaded rod is mounted on the upper part of one side of the base plate. The output end of the first servo motor is connected to one end of the threaded rod. The thread directions at both ends of the threaded rod are opposite. Threaded sleeves are symmetrically arranged on the outer side wall of the threaded rod. A mounting plate is mounted on the top end of the threaded sleeve. A cylinder is mounted on one end of the mounting plate. One end of the cylinder extends to the inner side of the mounting plate, and a positioning frame is mounted on one end of the cylinder.

[0007] A further improvement is that the positioning frame is designed in an E-shape, and plastic pads are provided on the inner side of the positioning frame.

[0008] A further improvement is that the limiting structure includes a limiting rod and a limiting sleeve. The limiting rod is installed on the lower side of one side of the base plate, and a limiting sleeve is provided on the outer side wall of the limiting rod. The top end of the limiting sleeve is connected to the bottom end of the threaded sleeve.

[0009] A further improvement is that the cross-section of the limiting rod is smaller than the cross-section of the limiting sleeve, and the limiting rod and the limiting sleeve form a sliding structure.

[0010] A further improvement is made in that: the rotating mechanism includes a mounting cavity, a worm, a worm wheel, and a second servo motor. The mounting cavity is installed inside the base plate. A worm is installed at one end inside the mounting cavity. A worm wheel meshes with one side of the worm. The top end of the worm wheel is connected to the bottom end of the support block. A second servo motor is installed at one end of the base plate. One end of the second servo motor is connected to one end of the worm.

[0011] A further improvement is that a counterweight is installed on one side of the top of the base plate, which makes the device more stable.

[0012] The beneficial effects of this utility model are as follows: By setting a positioning mechanism on one side above the base plate, the first servo motor, threaded rod, threaded sleeve, mounting plate, cylinder, positioning frame, limit rod, and limit sleeve of the positioning mechanism can drive two positioning frames to move. The two positioning frames are used to position the lifted automotive stamping die, making the automotive stamping die more stable during transportation, reducing hoisting swaying, lowering the risk of die damage, and improving installation accuracy and production efficiency, thereby greatly improving the practicality of the equipment in use. By setting a rotating mechanism inside the base plate, the mounting cavity, worm gear, worm wheel, and second servo motor of the rotating mechanism can drive the mounting frame and the main body of the lifting device to rotate, making the automotive stamping die more versatile when lifting and lowering.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a hoisting device for automotive stamping dies, including a base plate 1. Rollers 2 are installed at the four corners of the bottom end of the base plate 1. A controller 4 is installed at the front end of one side of the base plate 1. A support block 5 is installed on one side of the base plate 1. An mounting frame 6 is installed at the top of the support block 5. A lifting device body 7 is installed at one end of the mounting frame 6. A hook 8 is installed below the lifting device body 7 via a lifting rope. A rotating mechanism is provided below the support block 5. A positioning mechanism is provided on one side of the base plate 1.

[0020] The positioning mechanism includes a first servo motor 9, a threaded rod 10, a threaded sleeve 11, a mounting plate 12, a cylinder 13, a positioning frame 14, and a limiting structure. The first servo motor 9 is mounted on the front end of the base plate 1. The threaded rod 10 is mounted on the upper part of one side of the inside of the base plate 1. The output end of the first servo motor 9 is connected to one end of the threaded rod 10. The thread directions at both ends of the threaded rod 10 are opposite. Threaded sleeves 11 are symmetrically arranged on the outer wall of the threaded rod 10. The top end of the threaded sleeve 11 is mounted on the mounting plate 12. A cylinder 13 is mounted on one end of the mounting plate 12. One end of the cylinder 13 extends to the inner side of the mounting plate 12. The device is equipped with positioning frames 14. In use, the starting cylinder 13 drives the positioning frames 14 to move, so that the automotive stamping die is located inside the two positioning frames 14. Then, the first servo motor 9 is started to drive the threaded rod 10 to rotate. Therefore, under the limit of the limiting rod 15 and the limiting sleeve 16, the threaded rod 10 drives the threaded sleeve 11 to move, which in turn drives the two mounting plates 12 to move towards the middle. The two positioning frames 14 are used to position the automotive stamping die, making the automotive stamping die more stable during transportation, reducing shaking during hoisting, reducing the risk of die damage, and improving installation accuracy and production efficiency, thereby greatly improving the practicality of the equipment in use.

[0021] The positioning frame 14 is designed in an E-shape, and plastic pads are provided on the inner side of the positioning frame 14, so that it is not easy to damage it when positioning the automotive stamping die.

[0022] The limiting structure includes a limiting rod 15 and a limiting sleeve 16. The limiting rod 15 is installed on the lower side of one side of the base plate 1. The limiting sleeve 16 is provided on the outer side wall of the limiting rod 15. The top end of the limiting sleeve 16 is connected to the bottom end of the threaded sleeve 11. The cross-section of the limiting rod 15 is smaller than the cross-section of the limiting sleeve 16. The limiting rod 15 and the limiting sleeve 16 form a sliding structure. In use, the mutual cooperation between the limiting rod 15 and the limiting sleeve 16 can limit the movement of the threaded sleeve 11, making the threaded sleeve 11 more stable when moving.

[0023] The rotating mechanism includes a mounting cavity 17, a worm gear 18, a worm wheel 19, and a second servo motor 20. The mounting cavity 17 is installed inside the base plate 1. The worm gear 18 is installed at one end inside the mounting cavity 17, and the worm wheel 19 is meshed on one side of the worm gear 18. The top end of the worm wheel 19 is connected to the bottom end of the support block 5. The second servo motor 20 is installed at one end of the base plate 1, and one end of the second servo motor 20 is connected to one end of the worm gear 18. In use, the second servo motor 20 is started to drive the worm gear 18 to rotate. Since the worm gear 18 and the worm wheel 19 are meshed with each other, the worm wheel 19 is driven to rotate, which in turn drives the support block 5 to rotate, adjusting the lifting device body 7 to an appropriate position, thus improving the versatility of the automotive stamping die during lifting and lowering.

[0024] A counterweight 3 is installed on one side of the top of the base plate 1. The counterweight 3 makes the device more stable and improves the stability of the device during use.

[0025] Working principle: The operator first uses roller 2 to move the equipment to the appropriate position, then starts the second servo motor 20 to drive the worm gear 18 to rotate. Since the worm gear 18 and worm wheel 19 are meshed with each other, the worm wheel 19 is driven to rotate, which in turn drives the support block 5 to rotate, adjusting the lifting body 7 to the appropriate position. Then, the hook 8 is connected to the lifting hole of the automobile stamping die, and the lifting body 7 is started to lift the automobile stamping die. Then, the second servo motor 20 is started to drive it to rotate, rotating the hook 8 and the automobile stamping die to the top of the bottom plate 1. Then, the cylinder 13 is started to drive the positioning frame 14 to move, so that the automobile stamping die is located inside the two positioning frames 14. Then, the first servo motor 9 is started to drive the threaded rod 10 to rotate. Therefore, under the limit of the limit rod 15 and the limit sleeve 16, the threaded rod 10 drives the threaded sleeve 11 to move, which in turn drives the two mounting plates 12 to move towards the middle. The two positioning frames 14 are used to position the automobile stamping die, making the automobile stamping die more stable during transportation.
