Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a pneumatic control system for a shearing machine. Background Technology

[0002] Although there are many types of shearing machines currently in use, they are basically similar in terms of working principle and structure. Generally, the lower blade holder is fixed, and the workpiece to be processed is sent from the shearing machine's worktable to the position where the upper and lower blades interlock. Power is transmitted to the upper blade holder through the crankshaft, and the upper blade holder moves up and down in the sliding guide rail, thereby driving the upper blade to move up and down to complete the shearing of the workpiece to be processed.

[0003] For example, Chinese patent CN221125111U discloses an electrical control system for stacking materials after shearing, including a lifting pallet assembly, a safety detection assembly, a control assembly, a limit assembly, a magnetic detection assembly, and a lifting control assembly; the lifting pallet assembly is used for stacking materials after shearing; the magnetic detection assembly is installed on the lifting pallet assembly and is connected to the lifting control assembly, and is used to detect the position of the output end of the lifting pallet assembly and control the output of the lifting control assembly; the safety detection assembly is used to detect the height of the loading plate of the lifting pallet assembly, and is connected to the control assembly.

[0004] However, the technology has the following problems: After the air support system of the shearing machine tool described above shears the sheet metal, the sheet metal and the waste material from trimming are mixed together. Therefore, after the shearing machine shears the sheet metal, it is still necessary to manually separate the sheared sheet metal and waste material one by one. The workload is large, which increases the labor intensity of workers. Moreover, the waste material after shearing is easy to fall into the gap of the air support of the shearing machine and is not easy to remove. Over time, this has affected the normal operation of the shearing machine.

[0005] Based on this, this utility model designs a pneumatic control system for a shearing machine to solve the above problems. Utility Model Content
