[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an intelligent oil-immersed transformer housing stamping fixture, including a base 1, a lifting assembly 2, and a worktable 3. The lifting assembly 2 is fixedly connected to the upper surface of the base 1, and the worktable 3 is fixedly connected to the upper end of the lifting assembly 2. The lifting assembly 2 is used to adjust the height of the worktable 3. The lifting assembly 2 includes a support column 201, which is fixedly connected to the upper surface of the base 1. A rack 202 passes through the inside of the support column 201. A fixed platform 203 is fixedly connected to the side of the support column 201. A forward and reverse motor 208 is fixedly connected to the upper surface of the fixed platform 203. A gear 204 is fixedly connected to the other end of the output shaft of the forward and reverse motor 208, and the gear 204 meshes with the rack 202. The upper end of the rack 202 is fixedly connected to the lower surface of the workbench 3. The first slider 205 is fixedly connected to the side of the rack 202. The inner wall of the support column 201 is provided with a first groove 206. The first slider 205 is slidably connected in the first groove 206. There are two sets of the first slider 205 and the first groove 206, which are symmetrically arranged on both sides of the rack 202. The upper surface of the base 1 is fixedly connected to the telescopic rod 207. The upper end of the telescopic rod 207 is fixedly connected to the lower surface of the workbench 3. There are multiple sets of telescopic rods 207, which are arranged in a rectangular shape on the upper end of the base 1. The telescopic rod 207 is a multi-set of symmetrically arranged metal telescopic components. Each set consists of an outer tube and an inner tube, and the telescopic function is realized by using a nested structure. In this embodiment, by setting up the lifting assembly 2, the forward and reverse motor 208 drives the gear 204 to rotate, and the meshing transmission between the gear 204 and the rack 202 will drive the rack 202 to rise and fall vertically along the first slide groove 206 inside the support column 201. The first slider 205 cooperates with the first slide groove 206 to ensure the stability of the lifting. At the same time, multiple sets of rectangular telescopic rods 207 extend and retract synchronously, further improving the support strength of the workbench 3 when it is raised and lowered. In this way, the workers can adjust the workbench 3 to a comfortable operating height according to their own height, reduce bending over, reduce labor intensity, and thus bring convenience to the stamping processing of the intelligent oil-immersed transformer box.

[0018] Please see Figure 1 , Figure 2 and Figure 4A lower mold 4 is fixedly connected to the upper surface of the workbench 3. A support arm 5 is fixedly connected to the upper surface of the workbench 3. An electric push rod 6 is fixedly connected to the lower surface of the support arm 5. An upper mold 7 is fixedly connected to the lower end of the electric push rod 6. The upper mold 7 matches the lower mold 4. The upper mold 7 and the lower mold 4 are used for stamping and forming the intelligent oil-immersed transformer tank. A demolding assembly 8 is provided inside the lower mold 4. The demolding assembly 8 is used to demold the stamped intelligent oil-immersed transformer tank. The demolding assembly 8 includes a transmission chamber 801, which is opened inside the workbench 3. A dual-axis motor 803 is fixedly connected inside the transmission chamber 801. A threaded column 804 is fixedly connected to the other end of the output shaft of the dual-axis motor 803. There are two sets of threaded columns 804, which are symmetrically arranged at both ends of the output shaft of the dual-axis motor 803. A threaded tube 805 is threadedly connected to the other end of the threaded column 804. An arc-shaped inclined platform 806 is fixedly connected to the other end of the threaded tube 805. The upper surface of the lower mold 4 has a groove 807, inside which a push block 808 is installed. A movable rod 809 is fixedly connected to the lower surface of the push block 808. A through hole is provided on the surface of the groove 807, through which the movable rod 809 passes. The cross-section of the movable rod 809 and the cross-section of the through hole are both rectangular. A limit plate 810 is fixedly connected to the lower end of the movable rod 809. A spring 811 is sleeved on the surface of the movable rod 809. The upper end of the spring 811 is fixedly connected to a functional plate 810. The lower end of the spring 811 is fixedly connected to the upper surface of the limiting plate 810 on the inner wall of the energy compartment 802. A roller 812 is fixedly connected to the lower surface of the limiting plate 810. The lower end of the roller 812 overlaps the upper surface of the arc-shaped inclined platform 806. The arc surface of the arc-shaped inclined platform 806 matches the roller 812. A second slider 813 is fixedly connected to the lower surface of the arc-shaped inclined platform 806. A second groove 814 is opened on the inner wall of the energy compartment 802. The second slider 813 is slidably connected in the second groove 814.

[0019] In this embodiment, by setting up a demolding assembly 8, the threaded column 804 is driven to rotate by a dual-axis motor 803, which drives the threaded tube 805 and the arc-shaped inclined platform 806 to move horizontally. With the cooperation of the arc-shaped inclined platform 806 and the roller 812, the movable rod 809 and the push block 808 are pushed to rise vertically along the through hole, and the molded box is ejected from the lower mold 4. The entire demolding process does not require manual labor, thus bringing convenience to the demolding of the intelligent oil-immersed transformer box.

[0020] Please see Figure 1 and Figure 2 A wheel assembly 9 is fixedly connected to the lower surface of the base 1. Brake pads are provided on the side of the wheel assembly 9. There are multiple wheel assemblies 9, which are arranged in a rectangular shape at the lower end of the base 1. A push handle 10 is fixedly connected to the side of the workbench 3.

[0021] The working principle and usage process of this utility model are as follows: First, the operator pushes the tooling to the designated processing position by using the push handle 10 on the side of the workbench 3 and the wheel set 9 at the lower end of the base 1. Then, the operator steps on the brake pad on the side of the wheel set 9 to lock the wheel set 9, ensuring that the tooling remains stable during processing and avoiding displacement that could affect the stamping accuracy.

[0022] When the worktable 3 is raised, the forward and reverse motor 208 rotates forward, and its output shaft drives the gear 204 to rotate. The gear 204 meshes with the rack 202 to drive the rack 202 to rise along the inside of the support column 201. At the same time, the first slider 205 on the side of the rack 202 slides synchronously along the first groove 206 on the inner wall of the support column 201 to limit the lateral displacement of the rack 202 and ensure that the lifting direction is vertical. Meanwhile, the multiple sets of telescopic rods 207 on the upper surface of the base 1 extend synchronously with the rise of the worktable 3 to assist in supporting the worktable 3 and prevent tilting. When the worktable 3 is lowered, the forward and reverse motor 208 reverses, the gear 204 drives the rack 202 to descend, and the telescopic rod 207 retracts synchronously until the worktable 3 reaches the target height. Then the forward and reverse motor 208 is turned off, and the height setting is completed. Next, the staff placed the intelligent oil-immersed transformer box plate to be stamped on the upper surface of the lower mold 4, ensuring that the edge of the plate was aligned with the lower mold 4. Then, the electric push rod 6 on the lower surface of the support arm 5 was activated. The electric push rod 6 extended vertically downward and drove the upper mold 7 at the lower end to descend synchronously. Since the upper mold 7 and the lower mold 4 are structurally matched, as the upper mold 7 continues to press down, the plate will undergo plastic deformation under the squeezing action of the upper and lower molds, gradually conforming to the shape of the inner wall of the lower mold 4, forming a molded workpiece that fits the transformer box. The top edge of the molded workpiece will overlap the top perimeter of the lower mold 4 and be located above the push block 808. When the electric push rod 6 pushes the upper mold 7 to reach the preset stamping pressure, it will hold the pressure for a few seconds to ensure that the sheet metal is fully shaped and to avoid dimensional deviations in the formed workpiece due to springback. After the pressure holding is completed, the piston rod of the electric push rod 6 drives the upper mold 7 to rise vertically and return to the initial position. Secondly, the demolding assembly 8 inside the lower mold 4 is activated, causing the two output shafts of the dual-axis motor 803 to rotate synchronously, driving the threaded pillars 804, which are symmetrically arranged at both ends, to rotate in the same direction. The threaded pillars 804 are threadedly engaged with the threaded tube 805. When the threaded pillars 804 rotate, they drive the threaded tube 805 to move horizontally away from the dual-axis motor 803. The arc-shaped inclined platform 806 fixed at the end of the threaded tube 805 moves synchronously with the threaded tube 805. The arc surface of the arc-shaped inclined platform 806 is aligned with the lower end of the limiting plate 810. Matching the roller 812, as the inclined plane 806 moves, its arc surface generates an upward pushing force on the roller 812, pushing the limiting plate 810 to rise vertically. When the limiting plate 810 rises, it drives the upper movable rod 809 to rise synchronously along the rectangular through hole on the surface of the groove 807. The push block 808 at the upper end of the movable rod 809 rises with the movable rod 809, pushing the top edge of the transformer box formed from the bottom of the lower mold 4 upward until the top of the transformer box separates from the top edge of the lower mold 4. Finally, the worker easily lifts the formed transformer box upwards, allowing the transformer box to move out of the lower mold 4. At the same time, the dual-axis motor 803 reverses, driving the threaded column 804 to rotate in the opposite direction, and the threaded tube 805 and the arc-shaped inclined platform 806 to move closer to the dual-axis motor 803. At this time, the spring 811 sleeved on the surface of the movable rod 809 needs to restore its elastic deformation. Since its upper end is fixed to the inner wall of the functional compartment 802 and its lower end is fixed to the upper surface of the limit plate 810 and releases its elastic force, it can push the limit plate 810 to descend vertically, driving the movable rod 809 and the push block 808 to return to their initial positions, thus waiting for the next stamping cycle.
