Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for channel steel production. Background Technology

[0002] Channel steel is a long strip of steel with a U-shaped cross-section. Due to its excellent mechanical properties and structural stability, it is widely used in construction, bridges, machinery manufacturing, rail transportation, energy equipment and other fields as a key load-bearing component of beams, columns or supporting structures. In the processing of channel steel, punching is one of the core processes, which directly affects the efficiency of subsequent assembly and structural safety.

[0003] A search revealed Chinese patent application number 202323407369.8, which discloses a channel steel punching device. The device includes a support platform with multiple support legs fixedly connected to its lower surface. A storage cabinet is fixedly connected to one side of the lower surface of the support platform. The storage cabinet contains multiple sets of molds, each set including a bottom mold and a top mold, with each top mold having a different size. Each bottom mold has a corresponding die hole in its center. This invention includes a support platform, storage cabinet, multiple bottom molds, multiple top molds, mounting groove, positioning assembly, gantry frame, hydraulic rod, connecting seat, and locking assembly. The channel steel punching device in the aforementioned patent has the following drawback: the positioning assembly uses roller clamping, which can easily cause the channel steel to move during clamping, thus affecting processing accuracy.

[0028] This device is further configured such as Figure 1 As shown, a control box 3 is installed on one side of the main body 1 of the punching device. The control module inside the control box 3 is a Siemens S7-300 model. The control box 3 is equipped with a control system. The operator can input parameters such as the position, size, and quantity of punching through the human-machine interface. The control system automatically completes the positioning, clamping, punching and other processes.

By using the detachable mounting method of the pressing block 19, it is easy to match the required channel steel size, allowing the hydraulic rod 17 to clamp and fix the channel steel by driving the pressing block 19 downwards, thereby preventing the channel steel from moving during processing.

[0030] This device is further configured such as Figure 3As shown, the transverse clamping mechanism includes a slide rail 11, which is detachably mounted on its bottom via a bracket.

The quick-release connector 9 facilitates the rapid replacement of the punch head 10 as needed, thereby improving processing efficiency. The position of the punch head 10 is adjusted by using linear motor drive assembly 1 6 and linear motor drive assembly 2 7, and then the puncher 8 is used to press the punch head 10 to punch the channel steel.
