Abstract

The present invention belongs to the field of metal plate shearing technology, and is especially hydraulic rolling and cutting metal plate shearing machine. The metal plate shearing machine includes hydraulic cylinders, one transmission mechanism and one shearing mechanism; and features two hydraulic cylinders hinged horizontally on the frame, two piston rods, two link rods, two push rod and the upper shearing edge holder hinged successively, and one guide rod hinged between the upper shearing edge holder and the frame. The present invention has the advantages of simplified mechanism, simple and reliable transmission system and greatly raised sheared section quality.

Description

technical field [0001] The invention belongs to the technical field of metal plate shearing machines, and in particular relates to a hydraulic metal plate shearing machine. Background technique [0002] At present, there are many types of sheet metal rolling shears used at home and abroad, such as double-axis double-eccentric, single-axis double-eccentric, double-axis triple-eccentric, and hydraulic inclined-blade shears. They all have some disadvantages. The mechanical transmission type generally has a complex structure and a huge system. The stress on each component of the hydraulic inclined blade shears is not stable enough during the shearing process. Severe warpage, poor quality of sheared steel plate section, etc. Invention content: [0003] The purpose of the present invention is to provide a new technical solution, which can effectively overcome the defects in the prior art. [0004] The machine structure of the present invention includes a hydraulic cylinder, a ...
