When air cylinder group 35 was made up of the first cylinder 35a and the second cylinder 35b, fixing side by side and oppositely be provided with this connected mode except cylinder body, the first cylinder 35a and the second cylinder 35b also can adopt straight line to join.First piston boom end like the first cylinder 35a is fixedly connected with vertical transmission pedestal 3 through fixed support 36; The cylinder body afterbody of the first cylinder 35a is connected with second piston rod end of the second cylinder 35b, the cylinder body afterbody of the second cylinder 35b be connected support 37 and be connected; Perhaps the first piston boom end of the first cylinder 35a is connected with fixed support 36, and the cylinder body afterbody of the first cylinder 35a is connected with the cylinder body afterbody of the second cylinder 35b, second piston rod end of the second cylinder 35b be connected support 37 and be connected.Adopt this two kinds of modes that straight line joins; The number of cylinders of air cylinder group 35 can increase to three and more than; Correspondingly, the place, stroke position that slip drive rod 31 can arrive also can increase, and stamping knife 4 numbers also can increase accordingly; Slip drive rod 31 can freely be selected more stamping knife 4, has saved the replacing operation of stamping knife head 43 in the course of work.
Below be embodiment 3.Embodiment 3 is to the distortion of presser foot device on the basis of embodiment 1.
The presser feet 49 of presser foot device moves up and down with stamping knife head 43 in the course of the work, pushes down material prior to stamping knife head 43 during punching, and delays in stamping knife head 43 and leave material.
Shown in figure 10, the presser foot device of present embodiment comprises the back-moving spring 48 that is fixed in knife rest 41 bottoms, and back-moving spring 48 is sheathed on outside the stamping knife head 43, is connected with the presser feet 49 of annular in the lower end of back-moving spring 48.When not working, presser feet 49 is lower than the lower surface of stamping knife head 43.
When stamping knife 4 carried out the punching action, the presser feet 49 of stamping knife 4 was pushed down material prior to stamping knife head 43 contact materials.Stamping knife 4 continues to move downward subsequently, and back-moving spring 48 is compressed, and presser feet 49 keeps pushing down the state of material, and stamping knife head 43 passes the presser feet 49 of annular, on material, goes out the hole.When stamping knife 4 moved upward, back-moving spring 48 was resetted by elongation, and presser feet 49 keeps pushing down the state of material, and stamping knife head 43 moves upward away from material prior to presser feet 49, and presser feet 49 can prevent that stamping knife head 43 from causing upwarping of material when breaking away from material.
The most preferred embodiment of the utility model is illustrated, and various variations of being made by those of ordinary skills or remodeling can not break away from the scope of the utility model.
