[0002] Aluminum molds and their composite materials are widely used in the construction field. For example, they are used as formwork systems to support and position the concrete during pouring. Aluminum molds have excellent heat insulation, sound insulation, moisture resistance, fire resistance and other properties, and can meet the requirements of modern buildings for energy conservation and environmental protection. The first step in aluminum mold processing is to cut the aluminum alloy sheet according to the design requirements for subsequent processing. The shearing machine can complete this step efficiently and accurately to ensure that the size and shape of the cut meet the design requirements.

[0003] The shearing machine disclosed in the existing patent announcement number CN212121883U is equipped with a cylinder to drive the mobile cutter to move downward, automatically cut the plate, and reduce manpower and material resources. By setting a buffer spring, the moving speed is slowed down when the mobile cutter is about to contact the fixed cutter to prevent the fragile plate surface from breaking. By setting a guide roller, it is convenient to convey the plate body into the interior of the outer shell and move it above the fixed cutter. By setting a pulley and a slide groove, the movement of the mobile cutter is smoother. By setting a connecting table, the plate body is supported to prevent it from falling after being cut short, and it can make it more stable when shearing the plate and achieve better cutting effect. By setting a transparent observation window, it is convenient to observe the shearing situation inside the outer shell.

[0004] When the above device shears the plate, the plate is squeezed and easily moves, causing errors in the shearing of the plate and affecting the production quality. In view of the above problems, a shearing machine is proposed. Utility Model Content
