Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a gantry gate type plate shearing machine special for unwinding, leveling and shearing. Background Art

[0002] A shearing machine is a machine that shears plates by reciprocating linear motion with a movable blade and a matching fixed blade. It uses a moving upper blade and a fixed lower blade, and a reasonable blade gap to apply pressure to metal plates of different thicknesses and break and separate the plates according to the required size. A shearing machine is a type of forging machine, which is widely used in machining and can shear steel plates of various thicknesses. Commonly used shearing machines are divided into three types: flat shears, rolling shears and vibrating shears.

[0003] The patent specification with announcement number CN218982554U discloses a hydraulic gate shearing machine. When the hydraulic gate shearing machine needs to shear the workpiece, the workpiece is first placed on the placement table, and then the workpiece is positioned by a clamp. After positioning, the staff moves the workpiece backward to under the cutter. However, during the movement of the workpiece, the workpiece will drive the clamp to move backward, prompting the clamp to move inside the slide groove, and then the workpiece can be sheared by the cutter.

[0004] In the above technical scheme, after the workpiece is simply sheared by a single set of clamps, the workpiece located on the other side of the clamp is likely to roll up after shearing because there is no pressing effect of the clamp. This not only causes certain harm to the workers, but also is not conducive to the effect of continuous shearing. In view of this, a gantry gate shearing machine dedicated to unwinding, leveling and shearing is provided to overcome the above defects. Utility Model Content
