Bevel guide rail plate-shearing machine and shearing method thereof

Abstract

The invention discloses a bevel guide rail plate-shearing machine and a shearing method thereof and belongs to the field of mechanical manufacturing. The bevel guide rail plate-shearing machine comprises a material pressing beam, an upper knife blade, a lower knife blade, a knife rest and a feeding bracket. The upper knife blade is arranged on the lower portion of the knife rest. The lower knife blade and the feeding bracket are both arranged on a plate-shearing machine platform. A front guide rail is arranged on the right side surface of the knife rest. A back upper guide rail and a back lower guide rail are arranged on the left side surface of the knife rest. The included angle between the guide rail surface of the front guide rail and the knife rest, the included angle between the guide rail surface of the back upper guide rail and the knife rest and the included angle between the guide rail surface of the back lower guide rail and the knife rest are angles alpha, controlled by a controller and adjustable. The slope range of the guide rail surfaces is 0.06-0.08 mm. The front guide rail is connected with a front rolling wheel arranged on the left side surface of the material pressing beam. A back upper rolling wheel and a back lower rolling wheel move simultaneously and are both eccentric wheels. According to the bevel guide rail plate-shearing machine and the shearing method thereof, the perpendicularity and gap value between an upper knife and a lower knife can be automatically adjusted, and machining errors are small.

Description

technical field [0001] The invention relates to a hydraulic gate type shearing machine, which belongs to the field of mechanical manufacturing, and more specifically relates to a slope guide rail shearing machine and a shearing method thereof. Background technique [0002] At present, the angle structure between the moving surface of the tool holder on the mainstream shearing machine and the knife-edge surface is between 0.5 degrees and 1 degree. Such a structure is prone to processing errors during production and processing, and the two oil cylinders cannot be guaranteed to be on the same processing surface. Inside, it is generally corrected manually in the later stage, which will cause distortion and deformation of the shearing machine during the working process, which will affect the seal of the oil cylinder. During the shearing process, the upper knife and the lower knife will not interfere, but the impact The verticality of the upper knife and the lower knife is further...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problem that large processing errors are easy to occur in the production and processing of the existing shearing machine, the present invention provides a shearing machine with inclined plane guide rail and its shearing method, which can automatically adjust the vertical distance between the upper knife and the lower knife. Degree and gap value, small processing error
