[0018] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0020] like Figure 1-Figure 2 As shown, a punching and cutting integrated tool comprises an upper die base 1 and a lower die base 2 which are arranged relatively to each other. Both the upper die base 1 and the lower die base 2 can be assembled and installed together with a punching and cutting machine, and the power for the punching and cutting action is provided by the punching and cutting machine. At the same time, the upper die base 1 is provided with a plurality of positioning columns 3 which can be plugged and matched with the lower die base 2, so as to accurately position the upper die base 1 and the lower die base 2 for the punching and cutting action. In the present technical scheme, a plurality of positioning columns 3 are movably arranged on the pad 4; an outer contour punching and cutting knife 5 and an inner hole punching and cutting knife 6 are arranged on the side of the pad 4 facing the lower die base 2, and an inner hole punching and cutting column 7 which can pass through the pad 4 and the inner side of the inner hole punching and cutting knife 6 and can be plugged and matched with the lower die base 2 is arranged on the upper die base 1; the outer contour punching and cutting knife 5 and the inner hole punching and cutting knife 6 are both in the shape of a rounded rectangle.

[0021] In the above technical solution, specifically, the pad 4 can be assembled and installed together with the punching machine, and the power for the punching action of the pad 4 in cooperation with the upper die base 1 and the lower die base 2 is provided by the punching machine. Furthermore, the outer punching knife 5 and the inner hole punching knife 6 in the shape of a rounded rectangle can punch the touch panel into shape at one time when punching the touch panel.

[0022] Furthermore, in order to facilitate the discharge of the waste generated by punching, such as Figure 1 As shown, the lower die base 2 is provided with a discharge hole 201 that can be plugged with the inner hole punching column 7, and the discharge hole 201 passes through the lower die base 2. The waste material punched out by the inner hole punching knife 6 will be pushed into the discharge hole 201 by the inner hole punching column 7, which prevents the waste material from sticking and can also discharge the generated waste material from the discharge hole 201, which is convenient for the centralized collection and treatment of the waste material.

[0023] Furthermore, in this technical solution, if Figure 1As shown, the height of the inner hole punching knife 6 is smaller than that of the outer contour punching knife 5. When the punching machine drives the upper die seat 1 and the backing plate 4 to perform the punching action, the outer contour punching knife 5 will contact the sheet placed on the lower die seat 2 first, and by pressing down on the sheet, locate and fix the overall position of the sheet to be cut, so as to improve the accuracy of the inner hole punching knife 6 in punching the sheet.

[0024] In this embodiment, in order to increase the service life of the inner hole punching knife 6, the outer contour punching knife 5, and the inner hole punching column 7, the surfaces of the inner hole punching knife 6, the outer contour punching knife 5, and the inner hole punching column 7 are coated with a wear-resistant coating.

[0025] Furthermore, mounting holes 8 are provided on the upper die base 1 and the lower die base 2 to facilitate mounting the upper die base 1 and the lower die base 2 on the punching machine.

[0026] Furthermore, a plurality of positioning posts 3 are symmetrically distributed on the pad 4 to prevent the center of gravity of the pad 4 from shifting and reduce the sliding friction between the pad 4 and the positioning posts 3 .

[0027] Working principle: The upper die base 1, the lower die base 2 and the pad 4 can be assembled and installed together with the punching machine, and the punching and cutting integrated tool is driven by the punching and cutting machine as a power to perform the punching and cutting action. When the upper die base 1 moves toward the lower die base 2, the relative position between the upper die base 1 and the lower die base 2 is ensured by the plug-in cooperation of the several positioning columns 3 on the upper die base 1 and the lower die base 2. The outer contour punching knife 5 and the inner hole punching knife 6 in the shape of a rounded rectangle can punch out the outline of the touch panel (including chamfers) at one time when punching the plate placed on the lower die base 2. Through this device, the vertical surface and chamfer of the touch panel can be cut off after one punching and cutting action, which reduces the process and energy consumption, improves the production efficiency, and meets the needs of efficient production.

[0028] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
