Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-3, the present application provides a punching machine, including a base 1 and a supporting frame, wherein the bottom end of the supporting frame is fixed on the base, the supporting frame includes a first supporting body 2-1 and a second supporting body 2-2, a supporting body 3 is disposed between the first supporting body and the second supporting body, one end of the supporting body is connected with the first supporting body, the other end is connected with the second supporting body, a driving device 5 for driving a punch 4 to move up and down is fixed on the supporting frame, wherein the driving device may use the existing driving device, such as an electric hydraulic cylinder or a lifting motor, a die fixing platform 6 is disposed below the driving device, and one end of the die fixing platform is slidably connected with the supporting frame; the lower part of the die fixing platform is provided with an elastic piece, one end of the elastic piece is connected with the die fixing platform, the other end of the elastic piece is connected with the base, in the embodiment, the elastic piece is a spring 9, the base is provided with a guide post 10, the height of the guide post is smaller than or equal to that of the stand column, the spring is sleeved on the guide post, two sides of the elastic piece are provided with stand columns 7, the stand columns are positioned on the inner side of the die fixing platform, the stand columns are provided with cushion blocks 8, the cushion blocks can move forwards and backwards, are positioned on corresponding stand columns when moving to the front end position, are positioned on the outer side of the support frame when moving to the rear end position, and the height of the lower surface of the die fixing platform is larger than or equal to that of the upper surface of the cushion blocks in the original state.
