Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0019] according to Figures 1-6 As shown, a high-safety square tube punching press includes a punch 1, a base 2 below the punch 1, a positioning frame 3 on the base 2, a positioning groove 4 on the positioning frame 3 to allow the square tube to pass through, a through hole on the top of the positioning frame 3 to allow the punch 1 to pass through, a support frame 5 on one side of the positioning frame 3, a square guide post 6 rotatably mounted on the support frame 5, the square tube being sleeved on the guide post 6, a clamping assembly on the guide post 6 for clamping the end of the square tube, a conveying chain 7 below the guide post 6, a push plate 8 on the conveying chain 7, and the push plate 8 pushing the clamping component to move towards the positioning frame 3, so that the square tube passes through the positioning groove 4.

[0020] In the above specific technical solution, when it is necessary to punch a square tube, the square tube is first fitted onto the guide post 6 and fixed by the clamping assembly. Then, the conveyor chain 7 is started, and the push plate 8 on the conveyor chain 7 pushes the square tube to move in the direction of the positioning frame 3. The square tube is inserted into the positioning slot 4. According to the control program setting, after moving to the designated position, the push plate 8 stops moving, the punch 1 descends, passes through the through hole to punch the square tube, and then the punch 1 rises, and the square tube continues to move forward. After moving to the designated position, it is punched again, thus realizing accurate continuous punching of the square tube and improving the quality of the product. After punching is completed, the punch press stops working, and the operator disconnects the connection between the clamping assembly and the square tube. The operator pulls the square tube out from the other side where the square tube was inserted to complete the unloading. Then, the guide post 6 is rotated to move the guide post 6 away from the punch 1, and a new square tube is inserted into the guide post 6. The loading safety is high.

[0021] The positioning groove 4 is provided with a guide roller 9, which makes rolling contact with the square tube, so as to facilitate the square tube entering and exiting the positioning groove 4 and being pulled out of the positioning groove 4.

[0022] The clamping assembly includes a slider 10 that slides along the length of the guide post 6. A fixing plate 11 is installed at the bottom of the slider 10. The fixing plate 11 is threadedly connected to the screw rod 12. A clamping plate 13 is provided at the top of the screw rod 12. The clamping plate 13 is slidably connected to the slider 10. The top of the clamping plate 13 abuts against the square tube. A movable plate 14 that cooperates with the push plate 8 is installed on the slider 10. A movable groove is provided at the bottom of the guide post 6. The slider 10 is slidably connected to the guide post 6 through the movable groove. By rotating the screw rod 12, the clamping plate 13 can cooperate with the guide post 6 to clamp the square tube, thereby ensuring the accurate movement of the square tube. After the square tube is continuously punched, the screw rod 12 is rotated to remove the square tube. When a new square tube is installed, the square tube pushes the slider 10 to move it to the leftmost end of the movable groove.

[0023] The punch 1 is mounted on the lifting bracket 15. The lifting bracket 15 is connected to the output end of the hydraulic cylinder 16.

The right and front sides of the square shell are open structures, allowing the guide post 6 to rotate 90°. When a new square tube needs to be installed on the guide post 6, the guide post 6 is rotated 90° to move the end of the guide post 6 away from the punch 1, increasing the safety of the square tube installation. After the square tube is installed on the guide post 6, the guide post 6 is rotated in the opposite direction to make the guide post 6 and the positioning groove 4 on the same plane.

[0025] The conveying chain 7 is connected to the sprocket 20, which is mounted on the drive roller. The conveying chain 7 is installed inside the fixed housing 21. A support frame 5 is installed above the fixed housing 21. The push plate 8 is slidably connected to the top wall of the fixed housing 21. The top of the fixed housing 21 is provided with a sliding groove. The push plate 8 is slidably connected to the fixed housing 21 through the sliding groove. It is worth noting that the length of the sliding groove at the top of the fixed housing 21 is greater than the length of the moving groove at the bottom of the guide column 6. When the push plate 8 moves to the leftmost end of the sliding groove, the guide column 6 rotates, and the push plate 8 and the moving plate 14 will not interfere with each other.
