Problems solved by technology

However, for mechanical shearing machines, the pressing mechanism is fixed with the knife holder, and the pressing mechanism is driven by the knife holder to move, so it is difficult to directly install a horizontal pressing plate on the outside, lacking fixed support points, and three-point support cannot be realized

Abstract

The invention discloses a machining method for a mechanical plate shearing machine and belongs to the field of plate shearing machines. According to the mechanical plate shearing machine, the lower end of a front panel is provided with a protruding section, roller shaft holes are machined in a wall plate and a front panel, and a three-point supporting structure is applied to the mechanical plate shearing machine. The main machining method for the plate shearing machine comprises the steps that the roller shaft holes in the wall plate and the front panel are machined, next, a main shaft and a drive shaft are installed, then, the front panel and a bracket are welded and installed, integrated machining is carried out on an installed rack, the size precision of the roller shaft holes is guaranteed, and finally machining and installation of other components are carried out. By means of the machining method, the problem that a traditional mechanical plate shearing machine is heavy in abrasion is solved, by means of control over the machining sequence and a process, the size precision of the rack is improved, the product machining quality of the plate shearing machine is advantageously improved, and the service life of the plate shearing plate is advantageously prolonged.

Description

technical field [0001] The invention relates to the technical field of shearing machines, and more specifically relates to a mechanical shearing machine with three-point support and a processing method thereof. Background technique [0002] According to the power type, the shearing machine is divided into hydraulic shearing machine and mechanical shearing machine. The hydraulic shearing machine mainly relies on two hydraulic cylinders to drive the movement of the upper tool holder, so as to realize the shearing of the plate. It has stable performance, but the processing efficiency Low; the mechanical shearing machine is driven by a motor, and the knife holder moves up and down along the slide rail. The mechanical shearing machine has sufficient power and high efficiency, but the knife holder wears a lot and the noise is loud. Therefore, how to reduce the wear and tear of the tool rest of the mechanical shearing machine is a major problem to improve its performance. [0003]...
