The system usually includes components such as a special tool magazine, a rotating cross arm, a tool retracting device, a tool loading and unloading device and a robot, etc., which replaces the traditional manual tool changing with automated operations to solve the tedious and time-consuming problems in the tool changing process. For example, the automatic tool changing system of the slitting machine proposed in the publication number "CN214185524U" uses a rotating cross arm, including a base, and transverse guide rails are installed on both sides of the base. The transverse guide rails are arranged along the length direction of the base, and a transverse shift seat that can move along the transverse guide rails is installed on the transverse guide rails on both sides. The positive effect of the utility model is that the utility model pre-installs the used tools on multiple groups of cross arm shafts, and performs transverse movement and rotation of the whole device as needed to achieve docking with the main shaft of the longitudinal shearing machine, so as to facilitate the replacement of the tools on the longitudinal shearing machine. The operation process of loading and unloading the tools is only in opposite directions, and the other operations are the same. The process is simple, time-saving and labor-saving, and the labor intensity of the operators is effectively reduced, the efficiency of the tool changing operation is improved, and the production cost is greatly reduced compared with the traditional tool changing operation.

Then the staff activates the matching component to connect the mounting frame with the transmission component. Then the staff starts the transmission component to move the tool holder along the direction of the slide slot, so that one end of the tool holder fits with the end of the shear roller. At this time, the staff starts the hydraulic cylinder to drive the pressure block to move at its output end, so that the pressure block presses against the inner wall of the slide slot, thereby fixing the position of the tool holder.

During the tool change process, the selection and exchange of the annular blade is mainly achieved through the rotation of the rotating drum 4 and the movement of the tool holder 10 and the pushing frame 11, and the range of motion is limited. Therefore, the floor space occupied is greatly reduced compared with the cross-arm tool changing system, avoiding limiting the operating space and preventing affecting the operating efficiency and safety of the operator, while reducing the cost of renting or purchasing the site.
