Description

Positioning calculation module of cutting machine table and method of calibrating knife

The present invention relates to a cutting machine positioning calculation module and its calibration method, in particular to the technology that can calibrate the tool combination of the cutting machine, so that the tool can be corrected to the correct position to facilitate subsequent cutting When cutting, the maximum cutting quantity can be automatically compiled on the processed material, which can avoid the waste of processed materials and also improve the efficiency of the process.

According to the conventional cutting machine, before processing the material, the cutting mold needs to be set up, and the mold is adjusted to the required position, and then the material is cut. The mold will be directly punched on the material to cut the material out of the mold. The traditional mold system will have a knife die, which will be locked on the cutter head. When locking, the cutter head will be fixed by a clamping mechanism, and the position of the X axis and Y axis of the knife die will be manually corrected. In order to make the cutter die correctly fixed on the cutter head, if there is no correct relative position between the two, the material will leave many uncut places during the processing and cutting steps, resulting in material waste.

Chinese Patent Publication No. CN 104342512 A "Simple punching device with positioning structure" discloses a punching cutting device, which includes a punching plate and a punching device connected to the punching plate. The punching plate is vertically fixed with a positioning rod. The positioning rod described is located in the limit hole of the beam, so that the punching plate can only move vertically up and down, and will not shake left and right during the cutting process, so that the punching plate will not lose the correct position to ensure the cutting quality; Patent Bulletin No. TW M372777 "Eccentricity of Horizontal Punching Cutting Machine "Correction structure" discloses a transverse punching and cutting machine, which is provided with a power mechanism and a shaft driven by the power mechanism, and two sides are respectively provided with a linkage shaft and a linkage slider mechanism of the first mold.
