Schematic diagram of the structure and side view of the structure. As shown in the figure, the punching machine structure of the present invention is mainly composed of a base 20 and a punching element 30. The punching element 30 is connected to the base 20 so as to be supported by the base 20. The punching element 30, and the punching element 30 is mounted on a high-altitude position, so that there is a punching space between the punching element 30 and the ground or a plane, so that the punching space can provide the punching space. The hole element 30 has sufficient space when performing the punching operation to perform a punching action with, for example, a punch downward.

The base 20 includes a first outer frame 21, a second outer frame 22, a first inner frame 23, and a second inner frame 24. The first outer frame 21 is, for example, set at the front side (for example, FIG. 3 The upper position), and the second outer frame 22 is set at a rear position opposite to the front position (for example, the lower position in FIG. 3), and the second outer frame 22 is connected to the first outer frame 21 , Making the first outer frame 21 and the second outer frame 22 parallel to each other. In addition, in order to effectively support a punching force generated by the punching element 30, a first bending portion 211 is provided in a first direction (the X-axis direction in FIG. 4) of the first outer frame 21. The second outer frame 22 may also be provided with a second curved portion 221 in the first direction, and because the first outer frame 21 and the second outer frame 22 are parallel to each other, the first curved portion 211 and the second outer frame 22 are parallel to each other. The positions between the second bending portions 221 are also parallel to each other, so as to effectively withstand the bending stress A generated by the pressing force through the bending strength of the first bending portion 211 and the second bending portion 221.

The first inner frame 23 and the second inner frame 24 are frames arranged between the first outer frame 21 and the second outer frame 22, and the first outer frame 21 and the second outer frame 22 are The first inner frame 23 and the second inner frame 24 are frames erected in the high-altitude position. Therefore, when the first inner frame 23 is set on the first inner frame 23 and the second inner frame 24 The adjacent part of the outer frame 21 is connected to the first outer frame 21 via a first connecting element 25, so that the first inner frame 23 and the first outer frame 21 are parallel to each other, and the second inner frame 24 is Is arranged adjacent to the second outer frame 22 and connected to the second outer frame 21 via a second connecting element 26, so that the second inner frame 24 and the second outer frame 22 are parallel to each other, so The combination of the first outer frame 21 and the first inner frame 23 and the combination of the second outer frame 22 and the second inner frame 24 may be formed by a mirror image structure.

The punching element 30 is sandwiched between the first inner frame 23 and the second inner frame 24 (more specifically, the punching element 30 is separated from the first inner frame 23 and the second inner frame 24). The inner frame 24 is vertically sandwiched between the first inner frame 23 and the second inner frame 24) so as to be connected to the first inner frame 23 and The second inner frame 24 is connected. In addition, in order to enable the first inner frame 23 and the second inner frame 24 to further provide a supporting force opposite to the direction of the first curved portion 211 and the second curved portion 221, the There is a stress gap SG between the punching element 30 and a side surface of the first inner frame 23 and a side surface of the second inner frame 24, so that one side of the punching element 30 can pass through the first curved portion 211 and the second curved portion 221 support the punching force generated therefrom, but also through the first inner frame 23 and the second inner frame 24 on the stress spacing SG to support the punching element 30 on the other side This impulse force can achieve the effect of left-right balance.

In addition, since the punching element 30 is provided on an upper section of the base 20, the lower die 40 is provided on the lower section of the base 20, and the lower die 40 is provided on the base 20. 20 (the position between the first outer frame 21 and the second outer frame 22) and is located at a punching position F of the punching element 30, so when the punching element 30 is based on the punching position F When the trajectory performs a punching operation, for example, the punch on the punching element 30 will punch down to the position of the lower punch 40 to perform the punching action.

However, when the punching element 30 performs the punching operation, the punching force is relatively generated due to the downward punching action. At this time, the punching element 30 is located at the first curved portion 211 and the second The second curved portion 221 is located at the middle position and is connected between the first inner frame 23 and the second inner frame 24, so when the first curved portion 211 and the second curved portion 211 and the second inner frame are located on the side of the punching element 30 When the bending 221 receives the punching force, the inner arcs of the first bending portion 211 and the second bending portion 221 (that is, the position marked by the bending stress A) will correspondingly generate bending stress A, which is located on the punching element When the first inner frame 23 and the second inner frame 24 on the other side of 30 receive the pressing force, the first inner frame 23 and the second inner frame 24 at the stress interval SG will correspondingly generate bending stress B, and in this embodiment, the bending stress A and the bending stress B are the same stress.

In this way, through the above-mentioned multi-frame design and the positional arrangement of the punching elements, the problems caused by the restriction of the punching machine can be improved, and the open space at the front side of the punching machine can be effectively enlarged, and the inner frame and the curved part can also be penetrated. Provide sufficient supporting force to avoid problems such as tilt, high production cost, or insufficient space caused by the prior art.
