Detailed Description
The present invention will be described in detail with reference to the accompanying drawings, but the scope of the invention is not limited to the following examples, but is intended to cover all the modifications and equivalent changes within the scope of the present invention as defined by the appended claims and the description.
Referring to fig. 1-3, the pneumatic riveting machine without rivet connection of the invention comprises a frame 1, wherein a cylinder 2, a punching cutter bracket 3, a punching cutter 4, a punching cutter female die 5, a bracket guide rod 6, a back fastening block 7 and a stripping block 8 are arranged on the frame, the upper end of the punching cutter bracket is connected with the cylinder, and the cylinder can drive the punching cutter bracket to reciprocate along the left-right direction parallel to the axis direction of the cylinder; the punching cutter is arranged at the lower end of the punching cutter bracket, the edge of the punching cutter faces outwards towards the side face of the punching cutter bracket, the inner end of the bracket guide rod is fixed at the middle part of the punching cutter bracket, and the bracket guide rod and the punching cutter are positioned at the same side of the punching cutter bracket; the die of the punching cutter is fixed on the frame and is arranged corresponding to the interval of the punching cutter, and a feeding area is formed between the punching cutter and the die of the punching cutter; the middle part of the back-up block can be rotatably positioned on the frame through a rotating shaft 9, the outer end of the bracket guide rod is abutted against one side surface of the upper end of the back-up block, which is close to the punching cutter bracket, and the lower end of the back-up block is close to one side surface of the punching cutter bracket, which forms a back-up pressing part 71; the stripping block is fixed on the frame and positioned at one side of the punching cutter.
The reset spring 10 is elastically abutted against one side surface, far away from the punching cutter bracket, of the upper end of the back-up block, so that the upper end of the back-up block has a movement trend towards the punching cutter bracket. The die comprises a die base 41 and two die heads 42 symmetrically formed on a side of the die base remote from the die carrier. The frame is provided with limiting plates 11 respectively on the front and rear sides of the punching cutter, and the limiting plates form an eight-shaped feeding limiting groove corresponding to the feeding area.
