When the T-shaped material is transmitted, Figure 5 After the No. 3 mobile frame 404 rises, the No. 2 support rod 403 needs to be moved under the No. 3 mobile frame 404, and then the No. 1 electric cylinder 410 cylinder is released, allowing the No. 3 mobile frame 404 to be placed on the No. 2 support rod 403, and the workpiece is placed on the plane of the No. 3 mobile frame 404 for sawing. After cutting, it descends, so that the material can be directly transmitted, thereby guiding the T-shaped material. The use of a double-bracket structure can effectively realize the synchronous operation of feeding and discharging of T-shaped or materials. This design not only improves the stability and positioning accuracy of the material, but also reduces the risk of tilting and sliding of the material during transportation, thereby ensuring the quality of cutting and processing. At the same time, the use of a double-bracket structure makes the support of the material more uniform, reduces the dependence on manual labor, and reduces the burden on workers.
