[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-2 , the utility model provides an embodiment: a square tube punching device for a building climbing frame, including an operating platform 1, a top plate 2 is fixedly connected to the top of the operating platform 1, a hydraulic rod 3 is fixedly connected to the top of the top plate 2, a support plate 4 is fixedly connected to the output end of the hydraulic rod 3, an upper mold 6 is arranged at the bottom of the support plate 4, a lower mold 1 5 is fixedly connected to the top of the operating platform 1, a lower mold 2 7 is fixedly connected inside the operating platform 1, a top rod 8 is slidably connected inside the lower mold 2 7, both sides of the bottom of the top rod 8 are fixedly connected to a limiting block 1 9, a limiting assembly is arranged inside the operating platform 1, an upper towing hook 12 is fixedly connected to the bottom of the support plate 4, a lower towing hook 10 is fixedly connected to the top of the limiting block 9, and the upper towing hook 12 is buckled with the lower towing hook 10;

[0032] Specifically, in the stamping process, the step of placing the sheet on the lower die 5 is crucial. The accurate implementation of this step is the prerequisite for the smooth progress of the subsequent stamping process. Subsequently, the output end of the hydraulic rod 3 extends out, and through the transmission of the support plate 4, drives the upper die 6 and the lower die 7 to fit together. This fitting action is crucial to ensure the accuracy and stability of the stamping. When the output end of the hydraulic rod 3 retracts, a series of linkage actions begin to occur. First, the support plate 4 is lifted up. This action ensures the smooth separation of the molds. Subsequently, the upper towing hook 12 is buckled with the lower towing hook 10, driving the lower towing hook 12 to fit together. The hook 10 is lifted. The precise execution of this action is crucial to maintaining the integrity of the stamped parts. Driven by the lower towing hook 10 through the limit block 9, the push rod 8 begins to lift up and ejects the stamped parts from between the lower mold 5 and the lower mold 7. This operation not only ensures the smooth removal of the parts, but also prepares for the smooth progress of the next stamping process. It is worth noting that in the next stamping process, the descent of the support plate 4 and the synchronous descent of the upper towing hook 12 and the lower towing hook 10 are coordinated with each other. This high degree of synchronization ensures the continuity and efficiency of the stamping process.

[0033] Reference Figure 2 The limit block 9 is pushed to reset by the tension of the spring 11. This design enables the limit block 9 to quickly return to its original position after being acted upon by an external force. At the same time, the limit block 9 is penetrated through the outer wall of the limit column 23, which can effectively limit the movement range of other components.

[0034] Reference Figure 3-4 , a worm gear 15 is rotatably connected inside the support plate 4, a transmission shaft 16 is rotatably connected inside the support plate 4, one end of the transmission shaft 16 is fixedly connected to a handwheel 18, a worm 17 is fixedly connected to the outer wall of the transmission shaft 16, and the worm 17 is meshed with the outer wall of the worm gear 15, a connecting block 13 is fixedly connected to the top of the upper mold 6, a card slot 14 is provided inside the connecting block 13, a connecting disk 19 is fixedly connected to the top of the worm gear 15, a connecting rod 20 is rotatably connected to the inside of the connecting disk 19, one end of the connecting rod 20 is rotatably connected to a push rod 21, one end of the push rod 21 is fixedly connected to a limited block 22, a card block 24 is fixedly connected to the top of the limited block 22, and the outer wall of the card block 24 is embedded in the card slot 14, a telescopic rod 25 is arranged inside the support plate 4, and a spring 26 is sleeved on the outer wall of the telescopic rod 25, one end of the telescopic rod 25 and the spring 26 are fixedly connected to the inside of the support plate 4, and the other end of the telescopic rod 25 and the spring 26 are fixedly connected to one side of the limited block 22;

[0035] Specifically, when the upper mold 6 needs to be replaced, the operator only needs to gently rotate the hand wheel 18. This action will drive the transmission shaft 16 to start rotating. The rotation of the transmission shaft 16 further drives the worm 17 to rotate. The worm 17 is connected to the worm wheel 15. As the worm 17 rotates, the worm wheel 15 also starts to rotate. The worm wheel 15 transmits torque through the connecting plate 19 to make the push rod 21 at one end of the connecting rod 20 slide. During the sliding process, the push rod 21 will use the power of the limit block 22 to separate the block 24 from the slot 14. In this way, the upper mold 6 can be easily removed to prepare for replacing the new mold. When installing the new upper mold 6, the operator needs to first insert the connecting block 13 into the interior of the support plate 4, and then rotate the hand wheel 18 again to reset the block 24 and embed it into the interior of the slot 14. In this process, the block 24 will be assisted by the spring 26 to ensure that it is stably embedded in the slot 14 to prevent dislocation.

[0036] Working principle: When using the square tube punching device for building climbing frame, first, during punching, place the plate on the lower die 1 5, then the output end of the hydraulic rod 3 extends through the support plate 4 to drive the upper die 6 and the lower die 2 7 to engage and press the plate, then when the output end of the hydraulic rod 3 retracts, it drives the support plate 4 to be lifted, and at the same time, the lower towing hook 10 is driven to be lifted through the engagement of the upper towing hook 12 and the lower towing hook 10, and the lower towing hook 10 drives the ejector rod 8 to be lifted through the limit block 1 9, and the part is ejected from between the lower die 1 5 and the lower die 2 7, and during the next punching process, when the support plate 4 descends, the upper towing hook 12 and the lower towing hook 10 will also descend synchronously, and the limit is pushed by the tension of the spring 11. Block 1 9 assists in resetting. When the upper mold 6 needs to be replaced, it is only necessary to rotate the hand wheel 18 to drive the transmission shaft 16 to rotate, the transmission shaft 16 drives the worm 17 to rotate, the worm 17 drives the worm wheel 15 to rotate, and the worm wheel 15 drives the push rod 21 at one end of the connecting rod 20 to slide through the connecting plate 19, and the push rod 21 drives the block 24 to separate from the slot 14 through the limit block 22, and then the upper mold 6 can be removed for replacement. During installation, it is only necessary to insert the upper mold 6 into the support plate 4 through the connecting block 13, and then rotate the hand wheel 18 in the opposite direction to drive the block 24 to reset and embed it into the slot 14 to lock it. The block 24 is placed in an offset position with the auxiliary support of the spring 26.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
