[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Example 1

[0026] The current punching device is difficult to achieve continuous punching of the plate, which affects the production efficiency. Therefore, this embodiment provides a punching device for transformer production, such as Figures 1-6 As shown, it includes a cabinet 1, in which a waste box 9 for collecting waste sheets is placed at a position corresponding to a punching section 6 in the cabinet 1, and a side door is provided at a position corresponding to the waste box 9 in the cabinet 1. By opening the side door, the waste box 9 can be taken out regularly and the waste sheets inside can be cleaned. A processing table 2 is installed at the top of the cabinet 1, and a strip groove 10 is opened in the middle of the processing table 2. The width of the strip groove 10 is slightly larger than the width of the push rod 4. The top of the processing table 2 is sequentially provided with a storage member 3 for storing stacked sheets and a punching section 6 for punching a single group of sheets. The punching section 6 consists of a frame, a hydraulic rod movably mounted on the frame, and a punch head mounted on the movable end of the hydraulic rod. A guide path is provided between the storage member 3 and the punching section 6 to enable the sheets to be accurately moved to a position directly below the punching section 6. The guide path is composed of two sets of limit plates 5 fixed to the top of the processing table 2. The two sets of limit plates 5 are distributed on both sides of the strip groove 10 to prevent the sheets from shifting during movement. A retractable push rod 4 is provided in the cabinet 1 and moves along the strip groove 10. Figure 6 To determine the up and down, left and right directions as a benchmark, initially, the staff puts multiple sheets to be punched in the storage part 3, moves the push rod 4 to the left position of the storage part 3, controls the push rod 4 to extend the strip groove 10, and controls the push rod 4 to move from left to right. In the process of the push rod 4 passing through the storage part 3, the bottom layer of sheet material is pushed out from the storage part 3. As the push rod 4 continues to move, the sheet material is moved to the position directly below the stamping part 6, and stamping begins. After the stamping is completed, the push rod 4 is controlled to continue to move to the right to make the sheet material leave the position below the stamping part 6; then, the push rod 4 is controlled to retract into the cabinet 1, and then the push rod is driven to move left to its original position. Repeat the above operations, and the stacked sheets in the storage part 3 can be pushed out and punched in turn, thereby realizing continuous production, improving production efficiency, and reducing work intensity.

[0027] The storage part 3 includes a fence 31 fixed on the processing table 2. The side end of the fence 31 is provided with a notch 32 for the push rod 4 to pass through at the position corresponding to the strip groove 10. There are two groups of notches 32, which are distributed on both sides of the fence 31. An outlet 33 perpendicular to the notch 32 is provided at the bottom of the side end of the fence 31. The height of the outlet 33 is greater than the thickness of a single group of plates, but less than the thickness of the two groups of plates superimposed. When the push rod 4 moves from left to right and passes through the fence 31, the push rod 4 enters the fence 31 from the left notch 32, pushes the plate on the bottom side to move and pushes it out from the outlet 33. Due to the height limitation of the outlet 33, only a single plate can be pushed out at a time, and the other plates will be retained in the fence 31. The overall structure is relatively simple. When used with the push rod 4, continuous punching of the plates can be achieved, thereby improving production efficiency.

[0028] To control the push rod 4 in pushing the panels of the enclosure 31, a telescopic member 7 is installed within the cabinet 1 to control the push rod 4 from extending from the slot 10 or retracting into the cabinet 1. The telescopic member 7 includes a movable block 71 on which the push rod 4 slides. A hydraulic rod 72 is mounted at the bottom end of the movable block 71 to drive the push rod 4 vertically. By controlling the extension or contraction of the hydraulic rod 72, the push rod 4 can be driven to extend from the slot 10 or retract into the cabinet 1. A power member 8 is installed within the cabinet 1 to drive the movable block 71. The power member 8 includes a screw 82 rotatably mounted within the cabinet 1 and a guide rod 81 fixed within the cabinet 1. A reduction motor 83 is installed within the cabinet 1 to drive the screw 82 in rotation. The screw 82 is threadedly mounted to the movable block 71, and the guide rod 81 is slidably mounted to the movable block 71. By activating the reduction motor 83, the screw 82 rotates, which, constrained by the guide rod 81, drives the movable block 71, thereby driving the telescopic member 7 and the push rod 4 connected thereto. The telescopic member 7 is installed between the screw rod 82 and the guide rod 81 .

[0029] Example 2

[0030] Based on Example 1, Figure 3 The storage unit 3 further includes a plurality of groups of balls 34 mounted on the top of the processing table 2. The balls 34 are distributed in the enclosure 31. The contact surface between the bottommost plate, which is under greater pressure, and the processing table 2 is changed from sliding friction to rolling friction, thereby reducing the load on the reduction motor 83 and making it easier to push the plate out of the enclosure 31.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
