[0011] Figure 1 This is a schematic diagram of the working state structure of the utility model;

[0012] Figure 2 It is a schematic diagram of the state structure when the punching die head is replaced in the utility model.

[0013] In the figure: a stamping die head 1, a first thrust spring 2, a step guide head 3, a step channel 5, a roller 6, a pressure rod 7, a support rod 8, a hinge 9, a support shaft 10, a disk body 11, a stamping rod 12, a second thrust spring 13, and a frame 14. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] Reference Figure 1-2 A workpiece punching device comprises a frame 14 and a punching rod 12 connected to a punching machine. A vertically arranged support shaft 10 is fixedly connected to the frame 14. A disk body 11 with a vertically arranged axis is rotatably connected to the support shaft 10, and the disk body 11 can be moved and adjusted in the vertical direction along the support shaft 10. The purpose of the movement and adjustment is to insert the bottom end of the punching rod 12 into different step channels 5. The disk body 11 is located on the side of the support shaft 10 and is provided with a plurality of step channels 5. Each step channel 5 is penetrated by a step guide head 3 that can move vertically. A first thrust spring 2 is installed between the step guide head 3 and the step portion of the step channel 5. A punching die head 1 is fixedly connected to the bottom end of the step guide head 3. When working, the bottom end of the punching rod 12 can always be located in the step channel 5, that is, the upper stroke and the lower stroke of the bottom end of the punching rod 12 are both located in the step channel 5.

[0016] refer to Figure 1When the device is working, the punching machine drives the punching rod 12 to move up and down. Under the action of the punching rod 12 and the first thrust spring 2, the step guide head 3 moves back and forth up and down to realize the punching action of the punching die 1. When the punching die 1 needs to be replaced, the disk body 11 is adjusted to move it downward, so that the punching rod 12 is separated from the step channel 5, and then the disk body 11 is rotated to move the required punching die 1 to the bottom of the punching rod 12, and then the disk body 11 is adjusted to reset it, and then the punching can be performed. The punching die 1 of the device is easy and convenient to replace, and the structure is relatively simple and not easy to be damaged.

[0017] As an adjustment method, a second thrust spring 13 is sleeved on the support shaft 10, and the second thrust spring 13 is arranged between the disk body 11 and the frame 14. The second thrust spring 13 gives the disk body 11 an upward elastic thrust. When different stamping dies 1 need to be adjusted, the disk body 11 is pressed downward to disengage the stamping rod 12 from the stepped channel 5, and then the disk body 11 is rotated to replace a different stamping die head 1. The replacement is simple and convenient, and because the disk body 11 is flexibly connected to the support shaft 10 in the vertical direction, the device is prevented from being subjected to rigid impact, which is beneficial to extending the service life of the device, and the top end of the step guide head 3 can be better attached to the bottom end face of the stamping rod 12 to reduce noise pollution.

[0018] As an implementation mode, a pressing mechanism is installed between the support shaft 10 and the top surface of the disc body 11 , and the pressing mechanism can push the disc body 11 to move downward to make the punching rod 12 disengage from the stepped channel 5 .

[0019] As an implementation method of the pressing mechanism: the pressing mechanism includes a pressing rod 7, one end of which is rotatably connected to the support shaft 10 through a hinge 9, a support rod 8 is fixedly connected to the side of the pressing rod 7 close to the hinge 9, and a roller 6 is rotatably connected to the bottom of the support rod 8, and the projection of the axis of the roller 6 on the disk body 11 is arranged radially along the disk body 11.

[0020] refer to Figure 1 In the natural state, the second thrust spring 13 gives the plate 11 an upward elastic thrust to ensure that the punch rod 12 is always located in the stepped channel 5. When replacing the punch die head, refer to Figure 2 , press the pressure rod 7 downward, so that the roller 6 pushes the disc body 11 to move downward, and then the disc body 11 is rotated to replace different stamping dies, which is more labor-saving to use.

[0021] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
