[0018] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to its structure, and they are relative concepts. Therefore, it is possible to change accordingly according to its different positions and different usage states; so, these or other orientation terms should not be interpreted as restrictive terms.

[0019] As used in this specification, the singular forms "a", "the" and "said" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only for explaining this application and are not used to limit this application.

[0021] The present utility model provides a punching machine with adjustable die height as shown in the Figures 1-4 accompanying drawings, which includes a punching machine body 1. A hydraulic cylinder 2 is fixedly connected to the inner top of the punching machine body 1. The movable end of the hydraulic cylinder 2 is fixedly connected to a pressure plate 3. A slider 4 is arranged below the pressure plate 3. Both ends of the slider 4 are connected to the punching machine body 1 through a booster crank assembly 5, and the bottom of the booster crank assembly 5 is connected to a sliding seat 6. A die 7 is connected to the bottom of the sliding seat 6. A processing table 8 is arranged at the inner bottom of the punching machine body 1 and the processing table 8 is located below the die 7. Lifting guide assemblies 9 connected to the sliding seat 6 are arranged on both sides inside the punching machine body 1.

[0022] As Figure 1 and Figure 2 shown, two support bases 10 are fixedly connected to the bottom of the punching machine body 1 in the present utility model.

[0023] As Figure 1 , Figure 2 , Figure 3 shown, a guide post 11 passing through the slider 4 and the pressure plate 3 is fixedly connected to the top of the sliding seat 6 in the present utility model, and the guide post 11 is slidably connected to both the slider 4 and the pressure plate 3.

[0024] As Figure 3 and Figure 4 shown, the lifting guide assembly 9 in the present utility model includes a mounting plate 901 fixedly connected to the punching machine body 1. An adjustable slide rail 902 is mounted on the mounting plate 901. Two electric sliding tables 903 slidably connected to the adjustable slide rail 902 are fixedly connected to both sides of the sliding seat 6, and the electric sliding tables 903 cooperate with the adjustable slide rail 902.

[0025] As Figure 3 shown, the booster crank assembly 5 in the present utility model includes a first connecting rod 501 hinged to the slider 4. One end of the first connecting rod 501 is hinged to a second connecting rod 502 connected to the punching machine body 1 and a third connecting rod 503 connected to the sliding seat 6. The second connecting rod 502 is hinged to the punching machine body 1, and the third connecting rod 503 is hinged to the sliding seat 6.

[0026] Working principle: When the present utility model is specifically implemented, the hydraulic cylinder 2 controls the elongation of its movable end, causing the pressing plate 3 to move downward to contact the slider 4 and drive it to slide downward along the guiding column 11. Furthermore, the force is transmitted to the sliding seat 6 through the boosting crank arm assembly 5, thereby pushing the die 7 to move downward to punch the material on the processing table 8. When it is necessary to adjust the height of the die 7 to adapt to materials of different thicknesses, the movable end of the hydraulic cylinder 2 retracts, the pressing plate 3 moves upward, and the electric slide table controls it to slide upward along the adjustable slide rail. The sliding seat 6 moves upward accordingly, and the die 7 is also adjusted to the required height position.

[0027] The design of the boosting crank arm assembly 5 of the present utility model enables the die 7 to obtain greater pressure during the punching process, thus ensuring the accuracy and quality of the punching; the connecting rod structure design of the boosting crank arm assembly 5 enables the force transmission to be more uniform and efficient during the punching process, and at the same time reduces the load requirement for the hydraulic cylinder 2.

[0028] The lifting guiding assembly 9 of the present utility model ensures the stability and guiding accuracy of the die 7 in the vertical direction. Through the cooperation of the adjustable slide rail 902 and the electric slide table 903, the sliding seat 6 can maintain precise linear motion during the punching process, avoiding deviation and error, and the height of the sliding seat 6 can be adjusted by the electric slide table 903 after the punching is completed; at the same time, the design of the guiding column 11 ensures the stability and guiding accuracy of the slider 4 and the pressing plate 3 during the movement process, improving the processing accuracy and quality of the punching.

[0029] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
