Description

Technical Field

[0001] This invention relates to the field of stamping die hoisting technology, specifically a safe hoisting device for stamping dies. Background Technology

[0002] Due to their significant weight, stamping dies for vehicle exterior body panels typically require gantry cranes for loading and unloading from stamping equipment. Traditional gantry crane hoisting of stamping dies primarily involves using a main lifting chain to attach multiple auxiliary lifting chains to the lifting rings on the die. However, this method suffers from low stability during movement. Therefore, a cross-type lifting device is needed to assist in hoisting and improve stability. However, because the lifting surface of the cross-type lifting device is fixed, while stamping dies vary in size, the adaptability of the lifting device is limited. Therefore, a highly adaptable hoisting device is required, such as the stamping die hoisting and unloading device disclosed in CN118004870A. This application relates to the field of stamping die hoisting technology. It includes a hoist for connection with a gantry crane, an adjustment mechanism for adjusting the hoisting surface area of ​​the hoist, and a rotating ring mechanism for driving the adjustment mechanism to slide. An upper lifting ring for connection with the gantry crane's lifting chain is located in the middle of the hoist, and several lower lifting rings for hoisting the stamping die are located at the ends of the hoist. By setting crossbeams and longitudinal beams, the longitudinal beams can rotate around the middle of the crossbeams to adjust the hoisting surface area. The rotating ring mechanism on the crossbeams and longitudinal beams drives the adjustment mechanism to adjust the included angle between the crossbeams and longitudinal beams, thereby adjusting the hoisting surface of the hoist to accommodate the hoisting and unloading of stamping dies of different sizes, thus improving the hoisting stability of the stamping die.

[0003] However, the aforementioned hoisting and unloading device for stamping dies mainly adjusts the hoisting surface of the hanger by adjusting the included angle between the crossbeam and the longitudinal beam. Constrained by the first and second hinge beams, and relying on the included angle of the crossbeam and the longitudinal beam for adjustment, the range of adjustment of the hoisting surface is small. It can only be adjusted in a circular motion around the crossbeam and the longitudinal beam, and can only adjust the first and second hinge beams at the same time. It cannot achieve fine adjustment of the installation position and the lowering tilt angle of the stamping die through unilateral adjustment, resulting in low safety. Therefore, this application proposes a safe hoisting device for stamping dies. Summary of the Invention

[0004] This invention provides a safe hoisting device for stamping dies, which aims to solve the problem that the above-mentioned hoisting devices for stamping dies cannot achieve fine adjustment of the installation position and the lowering tilt angle of the stamping die through unilateral adjustment, resulting in low safety.

[0005] To achieve the above objectives, the present invention provides a safety hoisting device for stamping dies, comprising: At least two crossbeams; The lateral moving mechanism has a rectangular frame that is slidably disposed on both ends of a crossbeam.

[0008] Preferably, both the crossbeam and the longitudinal beam have toothed grooves on one side and limit grooves on the other side. Moving parts one and two are gear structures, meshing within the toothed grooves. Limiting parts one and two are roller structures, rotating within the limit grooves.

[0009] Preferably, a slide rail is provided at the lower end of the longitudinal beam, and a slide groove is provided at the bottom of the U-shaped frame, with the slide rail located in the slide groove.

[0010] Preferably, the lateral movement mechanism includes a drive motor and a lateral lead screw. The drive motor is connected to one side of the crossbeam, the lateral lead screw is rotatably disposed inside the crossbeam, the output end of the drive motor is connected to the lateral lead screw, and the moving part is threadedly connected to the lateral lead screw.

[0011] The longitudinal moving mechanism includes a second drive motor and a longitudinal lead screw. The second drive motor is connected to one side of the longitudinal beam, and the longitudinal lead screw is rotatably located inside the longitudinal beam. The output end of the second drive motor is connected to the longitudinal lead screw for transmission, and the second moving part is threadedly connected to the longitudinal lead screw.

[0012] Limiting grooves are provided on both sides of the crossbeam and the longitudinal beam. Limiting component one and limiting component two are roller structures, and the roller structure limiting component one and limiting component two are rolled in the limiting groove.

[0013] Preferably, the transverse lead screw and the longitudinal lead screw are respectively provided with external threads with opposite directions of thread, so that the two rectangular frames located on the same crossbeam can move relative to each other, and the two U-shaped frames on the longitudinal beam can move relative to each other.

[0014] Compared with existing technologies, it has the following beneficial effects: By using a hanger consisting of two horizontal beams and two vertical beams, and by adjusting the lifting area of ​​multiple lifting rings on the U-shaped frame through a lateral moving mechanism slidably mounted on the horizontal beams and a longitudinal moving mechanism slidably mounted on the longitudinal beams, the hanger can accommodate the lifting of stamping dies of different sizes. At the same time, the installation position and lowering tilt angle of the stamping die can be finely adjusted by sliding the lateral and longitudinal moving mechanisms, effectively improving the lifting safety of the stamping die.

Detailed Implementation To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: Example 1: like Figures 1 to 6 As shown, the present invention provides a safety hoisting device for stamping dies, comprising: Two crossbeams 1; The transverse moving mechanism 2 has a rectangular frame 21 slidably disposed on both ends of the crossbeam 1. The rectangular frame 21 is provided with a moving member 22 for moving within the crossbeam 1 and a limiting member 23 for rolling within the crossbeam 1. Two longitudinal beams 3 are fixedly connected to the bottom of the transverse moving mechanism 2 and remain perpendicular to the crossbeam 1; The longitudinal moving mechanism 4 has a U-shaped frame 41 slidably disposed on both ends of the longitudinal beam 3. The U-shaped frame 41 is provided with a moving part 42 for moving within the longitudinal beam 3, a limiting part 43 for rolling within the longitudinal beam 3, and a lifting ring 7 for lifting. The lateral moving mechanism 2 and the longitudinal moving mechanism 4 are configured to slide horizontally and longitudinally to adjust the horizontal lifting area of ​​multiple lifting rings 7 to accommodate the lifting of stamping dies of different sizes. At the same time, the installation position and lowering angle of the stamping die can be finely adjusted by sliding the lateral moving mechanism 2 and the longitudinal moving mechanism 4.

[0018] The gantry, consisting of two horizontal beams 1 and two vertical beams 3, adjusts the lifting area of ​​multiple lifting rings 7 on the U-shaped frame 41 via a lateral moving mechanism 2 and a longitudinal moving mechanism 4. Furthermore, the upper part of the rectangular frame 21 is also provided with lifting rings 7 for connection to the truss slings.

[0019] The working principle of this embodiment is as follows: the lateral moving mechanism 2 adjusts the lateral spacing of the two longitudinal beams 3 by moving on the crossbeam 1, and the longitudinal moving mechanism 4 adjusts the longitudinal spacing of the multiple lifting rings 7 on the U-shaped frame 41 by moving on the longitudinal beam 3, so as to realize the adjustment of the lifting area of ​​the rectangular lifting plane composed of multiple lifting rings 7.

[0020] Example 2: As another embodiment of the present invention, such as Figure 6 As shown, the lateral moving mechanism 2 also includes a drive motor 24, which is mounted on one side of the rectangular frame 21 via a bracket. The rectangular frame 21 is slidably mounted on the crossbeam 1, and the longitudinal beam 3 is fixedly connected to the bottom of the rectangular frame 21. The moving part 22 is drivenly connected to the output end of the drive motor 24 and is located on one side inside the rectangular frame 21. The limiting part 23 is rotatably connected to the other side inside the rectangular frame 21. Specifically, the drive motor 24 is drivenly connected to the moving part 22 via a reducer to drive the moving part 22 to rotate on one side inside the rectangular frame 21, so that the rectangular frame 21 slides on the crossbeam 1.

[0021] See Figure 4 The longitudinal moving mechanism 4 also includes a second drive motor 44, which is mounted on one side of the U-shaped frame 41 via a bracket. The U-shaped frame 41 is slidably mounted on the longitudinal beam 3. A second moving member 42 is drivenly connected to the output end of the second drive motor 44 and is located inside the U-shaped frame 41 on one side. A second limiting member 43 is rotatably connected to the other side inside the U-shaped frame 41. Specifically, the second drive motor 44 is drivenly connected to the second moving member 42 via a reducer to drive the second moving member 42 to rotate inside the U-shaped frame 41, thereby causing the U-shaped frame 41 to slide on the longitudinal beam 3.

[0022] See Figure 4 and Figure 6 Both the crossbeam 1 and the longitudinal beam 3 have toothed grooves 5 on one side, with racks at the bottom of the toothed grooves 5. Limiting grooves 6 are provided on the other side of the crossbeam 1 and the longitudinal beam 3. Moving parts 1 (22) and 2 (42) are gear structures, meshing with each other within the toothed grooves 5. Limiting parts 1 (23) and 2 (43) are roller structures, rotating within the limiting grooves 6 to stably limit the rectangular frame 21 on the crossbeam 1 and the U-shaped frame 41 on the longitudinal beam 3. This allows the rectangular frame 21 to move axially along the crossbeam 1 and the U-shaped frame 41 to move axially along the longitudinal beam 3, thereby adjusting the lifting area. Drive motor 24 and drive motor 44 drive moving parts 22 and 42 to rotate within the tooth groove 5 to achieve linear movement. The linear movement is limited by the limiting parts 23 and 43 on the other side of the rectangular frame 21 and the U-shaped frame 41, so that the rectangular frame 21 and the U-shaped frame 41 can slide linearly and stably on the crossbeam 1 and the longitudinal beam 3.

[0023] See Figure 4 The crossbeam 1 and the longitudinal beam 3 are provided with grooves on both sides. The grooves are connected to the toothed groove 5 and the limiting groove 6 respectively. The grooves are connected to the limiting blocks to prevent the rectangular frame 21 and the U-shaped frame 41 from sliding off the crossbeam 1 and the longitudinal beam 3.

[0024] See Figure 4 A slide rail 31 is provided at the lower end of the longitudinal beam 3, and a slide groove is provided at the bottom of the U-shaped frame 41. The slide rail 31 is located in the slide groove to further limit the sliding of the U-shaped frame 41, so that it can slide stably on the longitudinal beam 3.

[0025] The working principle of this embodiment is as follows: Drive motor 24 drives moving part 242 to rotate in the tooth groove 5 of the longitudinal beam 3, so that moving part 242 engaged in the tooth groove 5 drives U-shaped frame 41 to slide linearly on the longitudinal beam 3, thereby adjusting the longitudinal spacing of lifting rings 7 on multiple U-shaped frames 41; Drive motor 124 drives moving part 122 to rotate in the tooth groove 5 of the crossbeam 1, so that moving part 122 engaged in the tooth groove 5 drives rectangular frame 21 to slide linearly on the crossbeam 1, thereby adjusting the lateral spacing of lifting rings 7 on multiple U-shaped frames 41, so that multiple lifting rings 7 can adjust the lifting area in the horizontal lateral and vertical directions.

[0026] Example 3: As another embodiment of the present invention, such as Figures 7 to 9 As shown, the transverse moving mechanism 2 includes a drive motor 24 and a transverse lead screw 25. The drive motor 24 is connected to one side of the crossbeam 1, and the transverse lead screw 25 is rotatably disposed inside the crossbeam 1. The output end of the drive motor 24 is connected to the transverse lead screw 25 for transmission, and the moving part 22 is threadedly connected to the transverse lead screw 25.

[0027] See Figure 7 and Figure 10 The longitudinal moving mechanism 4 includes a second drive motor 44 and a longitudinal lead screw 45. The second drive motor 44 is connected to one side of the longitudinal beam 3, and the longitudinal lead screw 45 is rotatably disposed inside the longitudinal beam 3. The output end of the second drive motor 44 is connected to the longitudinal lead screw 45 for transmission, and the second moving part 42 is threadedly connected to the longitudinal lead screw 45.

[0028] See Figure 9 and Figure 10 Limiting grooves 6 are provided on both sides of the crossbeam 1 and the longitudinal beam 3. The limiting component 1 23 and the limiting component 2 43 are roller structures. The roller structure limiting component 1 23 and the limiting component 2 43 are rolled in the limiting grooves 6 to roll and limit the two sides of the rectangular frame 21 and the U-shaped frame 41, so that the rectangular frame 21 and the U-shaped frame 41 can slide stably on the crossbeam 1 and the longitudinal beam 3.

[0029] Specifically, the transverse lead screw 25 and the longitudinal lead screw 45 are respectively provided with external threads with opposite directions of rotation at both ends, so that the two rectangular frames 21 located on the same crossbeam 1 can move relative to each other, and the two U-shaped frames 41 on the longitudinal beam 3 can move relative to each other. When the drive motor 1 24 and the drive motor 2 44 are working, they drive the transverse lead screw 25 and the longitudinal lead screw 45 to rotate in the crossbeam 1 and the longitudinal beam 3, thereby driving the moving parts 1 22 and 2 42 at both ends of the transverse lead screw 25 and the longitudinal lead screw 45 to move relative to each other, thereby driving the lifting ring 7 at the bottom of the U-shaped frame 41 to move laterally and longitudinally in the horizontal direction, so as to adjust the lifting area of ​​the lifting structure composed of multiple lifting rings 7.

[0030] The working principle of this embodiment is as follows: Drive motor 24 drives the transverse lead screw 25 to rotate within the crossbeam 1, thereby causing the two rectangular frames 21 slidably connected to the crossbeam 1 to move relative to each other, thereby adjusting the transverse spacing of the two longitudinal beams 3; Drive motor 44 drives the longitudinal lead screw 45 to rotate within the longitudinal beam 3, thereby causing the two U-shaped frames 41 slidably connected to the longitudinal beam 3 to move relative to each other, thereby realizing the adjustment of the longitudinal spacing of the lifting ring 7.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
