Abstract
Description
Technical Field
[0001] The utility model provides a punching machine with a knife die pad fixing part, belonging to the technical field of punching die. Background Art
[0002] In the current punching and shearing machines, the knife die pad is fixed to the bottom of the punch by bolts and nuts. This method makes the pad installation very firm and flat. However, in actual production, the knife die and the pad are fixed in position. Since the knife die works on the knife die pad in the same position for a long time, the knife die pad is worn out and is easily scrapped at one time. The knife die pad in other positions is not used. The low utilization rate of the knife die pad increases the cost of consumables in the production process of the punching and shearing machine.

[0024] Embodiment
[0025] Figure 1This is a schematic diagram of the structure of the punching machine described in the present utility model. The schematic diagram shows a punching machine with a die holder fixing member, including a punch 1 and a workbench 2. A die 21 is fixed on the workbench. The punch includes a pressure plate 11, a fixing plate 12, and a punching backing plate 13. Both ends of the fixing plate 12 and the punching backing plate 13 extend beyond the pressure plate 11. At least two fixing members 3 are provided at both ends of the extended parts of the fixing plate and the punching backing plate. There are fixing screw holes 31 at the bottom of the fixing member. The fixing screw holes are evenly distributed at the bottom of the fixing member, and the number of screw holes is at least two. A fixing bolt 311 passes through the fixing screw hole and the holes in the fixing plate and the punching backing plate, and then is connected to the fixing screw hole, so that the fixing member, the fixing plate, and the punching backing plate are fixedly connected. There is a groove 32 in the middle of the fixing member. The groove of the fixing member is movably connected to the bottom of the punch, so that the fixing plate, the punching backing plate, and the fixing member are fixed to the bottom of the punch. There is a punch screw hole 14 on the side of the bottom of the punch. The groove of the fixing member and the punch screw hole are fixed by passing a groove bolt 321 through them. By tightening the groove bolt 321, the fixing member and the punch are connected tightly and cannot move. After the groove bolt is loosened, the fixing member hangs on the groove bolt and can be adjusted in position. The distance from the lower end of the groove 32 of the fixing member to the groove bolt is greater than the distance from the fixing plate to the pressure plate, to prevent the fixing member from being damaged due to excessive force when the pressure plate presses towards the fixing plate during production due to insufficient space distance. The distance that the fixing plate and the punching backing plate extend beyond the pressure plate is the sum of the width of the fixing member and the length of the fixing bolt. At this distance, when the moving area of the fixing member is maximized, it will not cause waste of the area of the fixing plate and the punching backing plate. The area contours of the fixing plate and the punching backing plate are the same size, and the consistent area contours are convenient for fixing and operation. There is a positioning hole 33 beside the groove of the fixing member. Tighten the positioning bolts 331 on the fixing members on both sides of the punch. The positioning bolts are tightly connected to the outer side of the bottom of the punch, so that the fixing member is positioned and fixed to prevent it from moving back and forth during production. There is a brake block 34 between the groove and the bolt. The brake block prevents the fixing member from shifting under the pressure of the punch during production. The height of the groove of the fixing member is greater than the thickness of the groove bolt, providing space for the fixing member to move up and down, preventing the pressure plate from not being able to contact the fixing plate due to too narrow a space, so that the punching machine can adapt to different types of dies, die holders, and fixing plates required by different products. The groove of the fixing member and the bolt are pulled by a mechanical hook or chain. The position adjustment between the groove of the fixing member and the groove bolt is achieved by pulling simultaneously from the grooves of the fixing members on both sides through a small mechanical hook or chain, realizing rapid position adjustment. One way to determine the position during the adjustment process is to fill part of the brake block in the groove of the fixing member. When the fixing member moves to the position of the brake block, it realizes fixed-point position movement.
[0026] When the punching machine is in use, lock the positioning bolt and the groove bolt to fix the fixing piece, the pressing plate, the die cushion plate and the punch. When adjustment is needed, rotate to loosen the positioning bolt and the groove bolt. Under manual or mechanical external force, the position of the groove of the fixing piece and the groove bolt changes, so as to adjust the position of the die cushion plate in the front, back, left and right directions, increase the utilization rate of the stamping cushion plate and reduce the cost of auxiliary materials. According to statistics, by adjusting the position of the die cushion plate through the fixing piece, the effective working range is expanded by 11%, saving the reinvestment of equipment and controlling the increase of fixed asset cost.
[0027] Although the present utility model has been disclosed above with a preferred embodiment, it is not intended to limit the present utility model. Any person familiar with this technology can make various modifications and decorations without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be defined by the claims.
