Technical Field
[0001] The utility model relates to the field of stamping dies, in particular to a stamping die which is convenient for replacing a punch. Background Art
[0002] Stamping is a metal processing process that involves the use of presses and dies to apply external force to metal materials such as plates, strips, tubes and profiles to produce workpieces with the desired shape and size through plastic deformation or separation. Such workpieces are usually called stampings.
[0003] However, the existing stamping dies have worn punches due to long-term use. There are deviations between the parts punched out by the worn punches and the standard parts. However, the current stamping die punches are fixed together with the die, which is not convenient for replacing the punches. The entire stamping die needs to be replaced, resulting in waste.
[0004] Therefore, in order to solve the above problems, we design a stamping die that is easy to replace the punch. Utility Model Content

The utility model provides a stamping die that is easy to replace the punch.
[0006] The technical solution of the utility model is: a stamping die for easy replacement of punches, comprising a lower die base, guide columns, an upper die base, a mounting frame, a punch body and a clamping block, a plurality of guide columns are arranged on the lower die base, the plurality of guide columns slidably penetrate the upper die base together, a mounting frame is installed at the bottom of the upper die base, the punch body is movably arranged in the mounting frame, notches are symmetrically opened on both sides of the mounting frame, a clamping block is slidably penetrated in the notch, and the clamping block is movably clamped with the punch body.
[0007] Furthermore, it also includes a stopper and a tension spring. The side surfaces of the clamping block are all equipped with a stopper, and the side surfaces of the stopper are equipped with a tension spring. The tension springs are respectively connected to the side surfaces of the installation frame.
[0008] Furthermore, a pull rod is included, and the two clamping blocks are slidably penetrated by the pull rod.
[0009] Furthermore, it also includes a support frame, which is symmetrically installed on the bottom of the upper mold base, and the pull rod slides through the support frame.
[0010] Furthermore, the pull rod movably pushes the clamping block.
[0011] Furthermore, it also includes a rubber sleeve, and the outer side of the pull rod is covered with the rubber sleeve.
[0012] The beneficial effects of the utility model are as follows: the clamping blocks are pulled to both sides, the clamping blocks move to both sides and leave the punch body, the clamping relationship is released, the old punch body is taken out downward, and the new punch body is squeezed upward into the installation frame, the punch body contacts the clamping blocks and is squeezed to both sides, and when the punch body reaches the top of the installation frame, the clamping blocks clamp the punch body, so as to achieve the effect of convenient replacement.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] Example 1
[0026] A punching die that is easy to replace the punch, such as Figure 1-Figure 10As shown, it includes a lower die base 1, a guide column 2, an upper die base 3, a mounting frame 4, a punch body 5 and a clamping block 6. A plurality of guide columns 2 are arranged on the lower die base 1, and the plurality of guide columns 2 slide through the upper die base 3 together. The number of the guide columns 2 is 4, which can be increased or decreased according to actual needs. A mounting frame 4 is installed at the bottom of the upper die base 3, and the punch body 5 is movably arranged in the mounting frame 4. Notches are symmetrically opened on both sides of the mounting frame 4, and a clamping block 6 slides through the notch, and the clamping block 6 is movably clamped with the punch body 5.
[0027] When the punch body 5 needs to be taken out, the block 6 is pulled to both sides, the block 6 moves to both sides along the notch, the block 6 leaves the punch body 5, hold the punch body 5, move it downward to take it out, bring the new punch body 5 close to the installation frame 4, push the punch body 5 upward, the punch body 5 moves into the installation frame 4, the punch body 5 squeezes the block 6, the block 6 moves backwards under the action of the squeezing force, the punch body 5 reaches the top of the installation frame 4, and is slidably engaged with the inner wall of the installation frame 4, and the block 6 clamps both sides of the punch body 5.
[0028] Example 2
[0029] On the basis of Example 1, Figure 5 and Figure 8 As shown, it also includes a block 7, a tension spring 8, a support frame 9, a pull rod 10 and a rubber sleeve 11. Blocks 7 are installed on the sides of the blocks 6, and tension springs 8 are installed on the sides of the block 7. The tension springs 8 are respectively connected to the sides of the installation frame 4. The two blocks 6 are slidably penetrated by the pull rod 10. There is a gap between the block 7 and the block 6 to facilitate the passage of the pull rod 10. The bottom of the upper mold base 3 is symmetrically installed with a support frame 9, the pull rod 10 slides through the support frame 9, the pull rod 10 movably pushes the block 6, and the outside of the pull rod 10 is covered with a rubber sleeve 11.
[0030] When the punch body 5 needs to be taken out, the pull rod 10 is pulled, and the pull rod 10 moves along the support frame 9. The moving pull rod 10 squeezes the block 7 outward, and the block 7 moves to both sides with the block 6. The block 6 leaves the punch body 5, and the punch body 5 can be taken out, which makes it easier to pull the block 6.
