An intermediate die is fixedly arranged on the side of the support die. Avoidance holes are arranged equidistantly along the horizontal direction at the top of the intermediate die. Bottom holes are arranged equidistantly below the avoidance holes of the support die. Holes with the same diameter as the bottom holes are arranged equidistantly at the bottom of the intermediate die. A driving component for driving the top die and the bottom die to simultaneously approach the support die is arranged on the side of the support die.

[0007] Optionally, positioning columns are fixedly arranged at the four corners of the bottom of the top die and the four corners of the top of the bottom die. Positioning holes are opened at the corresponding positions of the support die for the positioning columns.

[0008] Optionally, the driving assembly includes a left driving rack, an intermediate gear, a right driving rack, and a stepped column. The intermediate gear is rotatably connected to the side of the supporting die, and the bottom of the right driving rack is fixedly arranged on the side wall of the bottom die.

[0009] Optionally, a vertical groove is formed on the side of the right driving rack, and the stepped column passes through the vertical groove and is fixedly arranged on the side of the supporting die.

[0010] Optionally, a plurality of top punching columns are equidistantly arranged on one side of the bottom of the top die away from the positioning column, and a plurality of bottom punching columns are equidistantly arranged on the bottom die directly below the bottom hole.

[0011] Optionally, the top of the left driving rack is fixedly arranged on the side of the top die, and the left driving rack, the intermediate gear, and the right driving rack are meshed with each other.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. The main structure of the present utility model includes a top die, an intermediate die, and a bottom die.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Reference Figures 1-3 Figures 1-3 , a punching die for the carriage railing, includes a support table 6, a top die 3, a support die 5, and a bottom die 7. At the edge position of the top of the support table 6, a support frame 2 is fixedly arranged. At the edge position of the top of the support frame 2, a punching cylinder 1 is fixedly arranged. At the output end of the punching cylinder 1, a top die 3 is fixedly arranged. At the middle position of the top of the support table 6, a support die 5 is fixedly arranged. On the side of the support die 5, an intermediate die 4 is fixedly arranged. There is a certain gap between the bottom of the intermediate die 4 and the bottom of the support die 5, which facilitates the insertion of the intermediate die 4 into the carriage railing and enables the bottom die 7 and the top die 3 to punch the top and bottom of the carriage railing simultaneously.

[0020]

[0020] On the top of the intermediate die 4, avoidance holes 41 are arranged equidistantly in the horizontal direction. Below the avoidance holes 41 on the support die 5, bottom holes 51 are arranged equidistantly. At the bottom of the intermediate die 4, holes with the same diameter as the bottom holes 51 are arranged equidistantly. On the side of the support die 5, a driving component is arranged to drive the top die 3 and the bottom die 7 to approach the support die 5 simultaneously. At the four corners of the bottom of the top die 3 and the four corners of the top of the bottom die 7, positioning columns 13 are fixedly arranged. At the corresponding positions of the positioning columns 13 on the support die 5, positioning holes 12 are provided. The arrangement of the positioning columns 13 and the positioning holes 12 is used to position the vertical displacement of the top die 3 and the bottom die 7.

[0021]

[0021] The driving component includes a left driving tooth bar 8, an intermediate gear 11, a right driving tooth bar 15, and a stepped column 14. The intermediate gear 11 is rotatably connected to the side of the support die 5. The bottom of the right driving tooth bar 15 is fixedly arranged on the side wall of the bottom die 7. A vertical groove 16 is provided on the side of the right driving tooth bar 15. The stepped column 14 passes through the vertical groove 16 and is fixedly arranged on the side of the support die 5. On one side of the bottom of the top die 3 away from the positioning column 13, top punching columns 9 are arranged equidistantly.

[0022]

[0022] Below the bottom holes 51 on the bottom die 7, bottom punching columns 10 are arranged equidistantly. The top of the left driving tooth bar 8 is fixedly arranged on the side of the top die 3. The left driving tooth bar 8, the intermediate gear 11, and the right driving tooth bar 15 are meshed with each other. When the punching cylinder 1 extends to drive the top die 3 to move down, it will drive the bottom die 7 to move up through the right driving tooth bar 15, the intermediate gear 11, and the left driving tooth bar 8, and use the bottom punching columns 10 on the top of the bottom die 7 to complete the punching work on the bottom of the carriage railing.

[0023] The specific implementation steps and principles of the present utility model are as follows:

[0024] In the initial state, the stamping cylinder 1 is in the retracted state. After the worker inserts the carriage railing into the intermediate die 4, the worker activates the stamping cylinder 1. On the one hand, the stamping cylinder 1 drives the top die 3 to move downward, and the punching column 9 of the top die 3 is inserted into the avoidance hole 41 of the intermediate die 4 to punch a hole with a certain diameter in the top of the carriage railing. On the other hand, the stamping cylinder 1 drives the bottom die 7 to approach the support die 5 through the left driving tooth bar 8, the intermediate gear 11, and the right driving tooth bar 15. The bottom punching column 10 at the top of the bottom die 7 punches holes with different diameters in the bottom of the carriage railing sleeved on the intermediate die 4 after passing through the bottom hole 51.

[0025] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
