Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, this utility model provides a metal mold processing punch press that is easy to clamp, including a punch press main unit 1. The punch press main unit 1 has an upper positioning plate 3 and a lower positioning plate 2 respectively located at the top and bottom. Telescopic cylinders 6 and support seats 10 are respectively located on both sides of the lower part of the punch press main unit 1. A lower mold base 4 is placed above the lower positioning plate 2, and a T-shaped slider 402 is located below the lower mold base 4. The T-shaped slider 402 is inserted into the upper part of the lower positioning plate 2. A pushing block 7 is located above the telescopic cylinder 6, and one end of a rotating connecting clamping rod 8 is inserted into the upper part of the pushing block 7. The clamping rod 8... The connecting rod 9 is fitted inside the middle lower part and is clamped above the support base 10. The other end of the clamping rod 8 is provided with a positioning ball block 11. Both sides of the lower mold base 4 are provided with spherical grooves 401. The positioning ball block 11 is inserted and fixedly connected into the spherical grooves 401. The upper mold base 5 is installed below the upper positioning plate 3. T-shaped round blocks 13 are inserted into both sides of the upper positioning plate 3 and the upper mold base 5. The threaded rod 14 is fixedly connected below the T-shaped round block 13. The threaded rod 14 is fitted with a clamping block 15. The clamping block 15 is provided with a rubber pad 16 above it.

[0024] In this embodiment, the punch press host 1 has grooves 101 on both sides, and the lower part of the telescopic cylinder 6 is fixedly connected in the grooves 101. The telescopic cylinder 6 and the support base 10 are on the same vertical line, and the telescopic cylinder 6 and the support base 10 are both placed on both sides of the lower positioning plate 2 with a distance between them.

[0025] Furthermore, multiple T-slots 201 are provided above the lower positioning plate 2, and sliding T-slide blocks 402 are inserted into the T-slots 201.

[0026] The main body of the punch press 1 is equipped with telescopic cylinders 6 and support seats 10 on both sides, and push block 7, clamping rod 8 and connecting rod 9 are respectively provided between them. When the telescopic cylinder 6 is working, the push block 7 pushes one end of the clamping rod 8. Since the middle of the clamping rod 8 is restricted by the connecting rod 9, the clamping rod 8 can be flipped. The positioning ball block 11 located below the other end of the clamping rod 8 fixes the lower die seat 4 on the lower positioning plate 2. At the same time, the T-shaped slider 402 at the bottom of the lower die seat 4 is inserted into the upper part of the lower positioning plate 2, so that the lower die seat 4 will not slide above the lower positioning plate 2.

[0027] In this embodiment, a rotatable connecting pin 12 is inserted into the upper part of the pushing block 7 and into one end of the clamping rod 8, and a rotatable connecting pin 12 is inserted into the middle part of the clamping rod 8 and into the upper part of the connecting rod 9. At the same time, a rotatable connecting pin 12 is inserted into the lower part of the connecting rod 9 and into the support base 10.

[0028] After inserting pins 12 between the push block 7 and the clamping rod 8, between the clamping rod 8 and the connecting rod 9, and between the connecting rod 9 and the support base 10, the three pairs of structures are rotatably connected, so that the clamping rod 8 can be flipped during operation.

[0029] In this embodiment, multiple T-shaped openings 301 are provided on the side of the upper positioning plate 3, and multiple U-shaped openings 501 are provided on the side of the upper mold base 5. At the same time, the U-shaped openings 501 are connected to the lower part of the T-shaped openings 301.

[0030] Furthermore, a T-shaped round block 13 is inserted into the U-shaped opening 501 and the T-shaped opening 301, and the top of the rubber pad 16 is pressed against the lower sides of the upper mold base 5.

[0031] After inserting T-shaped round blocks 13 into both sides of the upper positioning plate 3 and the upper mold base 5, and with threaded rods 14 and clamping blocks 15 respectively below the T-shaped round blocks 13, rotating the clamping blocks 15 causes the rubber pads 16 to press against the lower sides of the upper mold base 5, so that the upper mold base 5 is fixed below the upper positioning plate 3.

[0032] In this embodiment, a pneumatic telescopic cylinder 18 is fixedly connected to the top of the punch press host 1, and the telescopic end of the pneumatic telescopic cylinder 18 extends through the top plate of the punch press host 1. At the same time, the bottom of the telescopic end of the pneumatic telescopic cylinder 18 is fixedly connected to the middle of the top of the positioning plate 3.

[0033] Furthermore, support rods 17 are provided at all four corners of the punch press host 1, and a controller 19 is provided on one side of the top of the punch press host 1.

[0034] After the pneumatic telescopic cylinder 18 is installed above the punch press host 1, it can drive the lower upper positioning plate 3 and the upper die base 5 to perform punching work, and the internal structure of the punch press host 1 is controlled by the controller 19.

[0035] Working principle:

[0036] The upper positioning plate 3 and lower positioning plate 2 are respectively provided on the upper and lower sides of the punch press main body 1. The telescopic cylinder 6 on both sides of the punch press main body 1 is connected to the support base 10 by the push block 7, the clamping rod 8 and the connecting rod 9 respectively. At the same time, the push block 7, the clamping rod 8 and the connecting rod 9 are inserted with pins 12. When the telescopic cylinder 6 is working, the push block 7 rises and pushes up the outer end of the clamping rod 8. However, because the middle part of the clamping rod 8 is limited by the length of the connecting rod 9, the inner end of the clamping rod 8 is pressed down. There is a positioning ball block 11 below the inner end of the clamping rod 8, and there are spherical grooves 401 on both sides of the lower die base 4. At this time, the lower end of the inner end of the clamping rod 8 is pressed down. On both sides above the lower mold base 4, the positioning ball blocks 11 are simultaneously inserted into the spherical grooves 401, thereby fixing the lower mold base 4 above the lower positioning plate 2 with the clamping rod 8. At the same time, a T-shaped groove 201 is provided in the upper part of the lower positioning plate 2, and a T-shaped slider 402 is provided below the lower mold base 4. The T-shaped slider 402 is inserted into the T-shaped groove 201. The cooperation between the T-shaped slider 402 and the T-shaped groove 201, together with the action of the clamping rod 8 and the positioning ball blocks 11, makes the lower mold base 4 fixed above the lower positioning plate 2, and it will not slide during operation. When it is necessary to replace the lower mold base 4, firstly, the telescopic cylinder 6 is retracted, so that the clamping rod 8 is flipped up, and then the lower mold base 4 can be pulled out.

[0037] T-shaped openings 301 and U-shaped openings 501 are respectively provided on both sides of the upper positioning plate 3 and the upper mold base 5, and the T-shaped openings 301 and U-shaped openings 501 are connected. T-shaped round blocks 13 are inserted into both of them. Threaded rods 14 and clamping blocks 15 are respectively provided below the T-shaped round blocks 13. When the clamping blocks 15 are rotated, the rubber pads 16 above the clamping blocks 15 are pressed against the lower sides of the upper mold base 5, so that the upper mold base 5 is fixed below the upper positioning plate 3.

[0038] In addition, when replacing the entire mold, the upper mold base 5 and the lower mold base 4 are in a combined state. At this time, first rotate the clamping block 15 to take out the T-shaped round block 13. Then the upper mold base 5 is released from the fixation. Then the lower mold base 4 is released from the fixation. Finally, the upper mold base 5 and the lower mold base 4 are pulled out together as a whole.
