A punching and shearing method of a double-head angle iron hydraulic combined punching and shearing machine

Abstract

The invention discloses a double-head angle iron hydraulic combined punching and shearing machine and a punching shear method thereof, and belongs to the technical field of machining equipment. The double-head angle iron hydraulic combined punching and shearing machine comprises a first operation area and a second operation area, the first operation area and the second operation area are mirror symmetrical with the central axis as the axis, wherein the second operation area comprises a knife plate matching mechanism, a knife plate in the knife plate matching mechanism is connected with an eccentric shaft, and a moving knife plate is matched with a static knife plate by rotating the eccentric shaft. The double-head angle iron hydraulic combined punching and shearing machine is a special machine for angle iron shearing, mainly solves the problem of shearing inconvenience caused by opposite direction of an angle steel cutting angle Moreover, the double-head angle iron hydraulic combined punching and shearing machine is improved concerning other defects of existing punching and shearing machine, the use effect of the punching and shearing machine is improved, and the economic benefit is good.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, and more specifically relates to a double-head angle iron hydraulic combined punching and shearing machine and a punching and shearing method thereof. Background technique [0002] Currently used punching and shearing machines mainly include flywheel punching and shearing machines and hydraulic combined punching and shearing machines, which gradually develop from single punching, shearing or bending functions to multifunctional functions. Among them, the hydraulic combined punching and shearing machine generally has five stations: standard punching station, angle steel section steel shearing station, bar shearing station, plate shearing station, corner cutting station, etc., which can realize multiple Various types of steel and plates are processed to achieve the effect of one machine with multiple functions. [0003] However, although the functions of the existing punchi...
