[0034] Reference Figure 3-Figure 5 The fixed assembly 5 includes a moving seat 51, the inner wall of the moving seat 51 is rotatably connected with a rotating disk 53, the top of the outer wall of the rotating disk 53 is fixedly connected with a fixed block 52, the fixed block 52 is slidably connected to the inner wall of the moving seat 51, the shape of the fixed block 52 is matched with the arc groove provided on the surface of the moving seat 51, and the rotating disk 53 can be driven to rotate on the inner wall of the moving seat 51 by moving the fixed block 52, the inner wall of the moving seat 51 is slidably connected with two groups of clamping blocks 54, the surface of the moving seat 51 is provided with two groups of linear guide grooves, so that when the clamping blocks 54 move toward each other on the inner wall of the rotating disk 53, no arc motion will be generated, and only lateral movement can be performed, the surface of the rotating disk 53 is provided with two groups of arc grooves, and the clamping blocks 54 are slidably connected to The inner wall of the arc groove of the rotating disk 53 allows the bottom end of the clamping block 54 to move in the arc groove through the rotation of the rotating disk 53, so as to achieve the movement toward each other or away from each other. The inner wall of the fixed block 52 is elastically connected with the pressing block 56 through the limiting spring 55. One end of the limiting spring 55 is fixedly connected to the inner wall of the fixed block 52, and the other end of the limiting spring 55 is fixedly connected to the outer wall of the pressing block 56. The function of the limiting spring 55 is to reset the position of the pressing block 56 when it moves. The pressing block 56 is slidably connected to the inner wall of the fixed block 52. The inner wall of the movable seat 51 is provided with multiple groups of slots, and the pressing block 56 is plugged into the inner wall of the slot. The plugging between the two fixes the rotating disk 53 at multiple positions of the inner wall of the movable seat 51 when it rotates.

[0035] Reference Figure 2 and Figure 6 The top end of the outer wall of the workbench 1 is fixedly connected with a fixed plate 6, and the outer wall at the top of the fixed plate 6 is fixedly connected with an electric telescopic rod 7. The electric telescopic rod 7 is a prior art, and is controlled by an electric control device to drive the upper mold 9 to rise or fall synchronously to stamp the laminated sheets. The bottom end of the outer wall of the electric telescopic rod 7 is provided with a mounting assembly 8, and the electric telescopic rod 7 is detachably mounted with the upper mold 9 through the mounting assembly 8. The bottom end of the outer wall of the electric telescopic rod 7 is fixedly connected with a mounting seat 81, and the top end of the outer wall of the upper mold 9 is fixedly connected with two groups of guide blocks 10, and the guide blocks 10 are slidably connected to the inner wall at the bottom end of the mounting seat 81. The inner wall at the bottom end of the mounting seat 81 is provided with two groups of sliding grooves that fit the guide blocks 10, so that the upper mold 9 has a positioning effect during installation.

[0036] Reference Figure 6 The mounting assembly 8 includes a mounting seat 81, and the inner wall of the mounting seat 81 is elastically connected with two groups of L rods 85 through a return spring 84. The L rods 85 are slidably connected to the inner wall of the mounting seat 81. The inner wall of the mounting seat 81 is provided with a slide groove that fits the two sides of the L rod 85, so that the L rod 85 can only move in the slide groove. The outer wall of the guide block 10 is provided with a through hole, and the L rod 85 is plugged into the inner wall of the through hole. The plugging between the two fixes the guide block 10 and the upper mold 9 to the inner wall of the mounting seat 81. One end of the return spring 84 is fixedly connected to the outer wall of the L rod 85, and the other end of the return spring 84 is fixed. Connected to the inner wall of the mounting seat 81, the inner wall of the mounting seat 81 is slidably connected with a trapezoidal block 82. The reset spring 84 can reset the L rod 85 when it moves. The outer walls on both sides of the trapezoidal block 82 are in contact with the outer walls of the L rod 85. The inclined surfaces on both sides of the trapezoidal block 82 are used to squeeze the inclined surfaces of the L rod 85, so that the two groups of L rods 85 are moved outward synchronously. The outer wall of the trapezoidal block 82 is fixedly connected with a moving rod 83, and the moving rod 83 is slidably connected to the inner wall of the mounting seat 81. By setting the moving rod 83, the trapezoidal block 82 can be pushed to move on the inner wall of the mounting seat 81.

[0037] Working principle: when stamping the transformer laminations, the upper die 9 can be replaced according to the transformer laminations. First, the moving rod 83 is grasped to push the trapezoidal block 82 to move on the inner wall of the mounting seat 81. When the trapezoidal block 82 moves, the outer walls on both sides thereof will squeeze the inclined surfaces of the L rods 85 to allow the two groups of L rods 85 to move outward synchronously. When the L rods 85 move, the reset spring 84 will be compressed, and at the same time, it will also be separated from the through hole of the guide block 10 at the top of the upper die 9, so that the upper die 9 can be taken out from the inner wall of the mounting seat 81, so as to quickly disassemble it. At this time, the guide block 10 at the top of the upper die 9 of the corresponding lamination can be inserted into the inner wall of the mounting seat 81, and the moving rod 83 is released at this time. At the same time, the trapezoidal block 82 will cancel the squeezing of the inclined surfaces of the two groups of L rods 85. At this time, the two groups of L rods 85 will be subjected to the elastic action of the reset spring 84, and will be restored to their initial positions, so as to be plugged into the through hole of the guide block 10, so as to quickly install the upper die 9.

[0038] When the upper mold 9 is replaced, the laminate is placed between the two groups of clamping blocks 54 on the surface of the moving seat 51. At this time, the pressing block 56 can be moved on the inner wall of the fixed block 52 by pressing the pressing block 56, and the pressing block 56 can be disengaged from the card slot of the current position of the moving seat 51, and the limit spring 55 can be elastically compressed when the pressing block 56 moves. At this time, the fixed block 52 can be rotated to drive the rotating disk 53 to rotate on the inner wall of the moving seat 51. When the rotating disk 53 rotates, the two groups of clamping blocks 54 sliding in the arc grooves on its surface will move toward each other, and because the surface of the clamping block 54 is slidably connected to the linear guide groove of the moving seat 51, the two groups of clamping blocks 54 will move linearly toward each other, thereby quickly fixing the laminate, and at this time, the pressing block 56 can be released and it will be elastically acted upon by the limit spring 55 to restore it to its initial position to engage with the card slot of the current position of the moving seat 51, thereby fixing the position of the rotating disk 53 and the clamping block 54.

[0039] At the same time, when punching different positions of the stack through the upper die 9, the motor 2 can be started to allow its output shaft to drive the reciprocating screw 4 to rotate. When the reciprocating screw 4 rotates, it will drive the moving seat 51 to move laterally on the inner wall of the workbench 1, so that it can be adjusted according to the position of the stack to be punched, and there is no need to release the fixation of the stack before adjusting the position of the stack.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
