A precision cutting machine and cutting method for oblique section of profiles

Abstract

The invention discloses an accurate cutting machine and a cutting method for an inclined section of sectional materials. The cutting machine comprises a movable base, wherein the movable base is provided with a vertical supporting arm, a shaft sleeve is arranged on the supporting arm, and a gap is formed between the shaft sleeve and the supporting arm in a clearance fit mode; the shaft sleeve is provided with a first supporting rod in the horizontal direction, the tail end of the first supporting rod is connected with a second supporting rod, the first supporting rod and the second supportingrod are in clearance fit, a third supporting rod is arranged at the tail end of the second supporting rod, one end of the third supporting rod is provided with an operation handle, and the other end of the third supporting rod is provided with a cutting knife; a first rotating angle ruler is arranged on the upper surface of the shaft sleeve, and a second rotating angle ruler is arranged on the outer surface of the first supporting rod; and the cutting machine realizes multi-degree-of-freedom adjustment through the rotating shaft sleeve and the second supporting rod, and the cutting angle of the cutting knife is adjusted. The device is convenient to carry and convenient to operate, accurate angle adjustment can be realized, user requirements can be met, the inclined section of any angle canbe accurately cut, and the cutting machine can be widely applied to the field of sectional material processing.

Description

technical field [0001] The invention relates to the field of profile cutting, in particular to a precision cutting machine and a cutting method for oblique sections of profiles. Background technique [0002] When cutting profiles such as aluminum materials at the construction site, size deviations are often encountered. For profiles that are relatively large and inconvenient to carry or have been installed and fixed and are inconvenient to disassemble, the cutting machine needs to be placed in the waiting area. Cut the appropriate position of the profile, and cut the profile on site. Therefore, the cutting machine is required to have the characteristics of easy movement and portability. Moreover, when the profile is processed and installed, sometimes a certain angle of oblique section is required. If the angle error of the cut oblique section is large, the installation will fail, which will greatly increase the scrap rate of profile cutting. Therefore, the profile cutting m...

Problems solved by technology

Moreover, when the profile is processed and installed, sometimes a certain angle of oblique section is required. If the angle error of the cut oblique section is large, the installation will fail, which will greatly increase the scrap rate of profile cutting. Therefore, the profile cutting machine is required to have multiple degrees of freedom. Cutting Features

[0003] However, the current free cross-section cutting of profiles has unsteady cutting, and the angle and dimension error of the cut cross-section is relatively large, which is not convenient for the later installation of aluminum materials, which greatly increases the scrap rate of aluminum cutting, and some profiles after installation and fixing Or it is not convenient to transport the relatively large profiles to the platform of a more accurate aluminum material cutting machine, and the existing manual aluminum material cutting machine cannot meet the requirements of precision
