The cutting mechanism 230 comprises a gantry stand 231, a driving assembly, a mounting plate 232, a synchronizing wheel, a driving motor and a diamond wire saw 400, wherein the gantry stand 231 is positioned right above the working platform 210, and the mounting plate 232 is longitudinally connected to the gantry stand 231 in a sliding manner; the number of the synchronous wheels is multiple, in one embodiment, the number of the synchronous wheels is three, and the diamond wire saw 400 is in transmission connection between the synchronous wheels; a driving motor is connected to the axial direction of one of the synchronous wheels, and the diamond wire saw 400 is driven by the driving motor to drive, wherein the horizontal part of the diamond wire saw 400 is used as a cutting part for cutting the ingot 100; the driving assembly is connected to the gantry frame 231 and is used for driving the mounting plate 232 and the diamond wire saw 400 to move longitudinally, wherein the driving assembly can be driven in a screw rod or the like, so that the mounting plate 232 can move up and down.

Working principle/steps:

the cutter withdrawing device of the guillotine shear is used for driving the crystal bar 100 which is cut to move, so that the cutting gap 101 of the crystal bar 100 is widened, and secondary cutting of the end face of the crystal bar 100 in the cutter withdrawing process of a diamond wire is prevented.

After the ingot 100 is cut, the diamond wire saw 400 is positioned in the accommodating space 214 below the crystal; at this time, the sliced ingot 100 is driven to be lifted in the first direction by the lifting means, so that the cutting gap 101 of the ingot 100 is widened.

Specifically, the lifting shaft 3212 is driven to lift along the first direction by the cylinder 3213, so that the lifting plate 3214 is communicated with the lifting shaft 3212 to lift along the first direction, and in the lifting process of the lifting plate 3214, the lifting plate 3214 acts on the ingot 100, so that the ingot 100 is driven and lifted along the first direction, and the cutting gap 101 of the ingot 100 is gradually widened. After the cutting gap 101 is widened, the end surface of the ingot 100 is not cut secondarily during the upward movement and retracting process of the diamond wire saw 400.

The technical effects are as follows:

1. according to the method, the cut crystal bar 100 is driven by the driving mechanism, the crystal bar 100 moves towards the direction far away from the cutting gap 101 under the driving action, so that the cutting gap 101 of the crystal bar 100 is gradually widened, when the diamond wire saw 400 retracts, the diamond wire saw 400 cannot perform secondary cutting with the end face of the crystal bar 100, and the technical problem of inconvenience in retracting in the prior art is solved; achieving the technical effect of convenient tool withdrawal.

2. According to the ingot 100 cutting device, the lifting assembly 321 lifts the cut ingot 100 along the first direction, the lifting shaft 3212 in the lifting assembly 321 acts on the cut ingot 100 through the lifting plate 3214 to increase the stress area on the ingot 100, so that the stress stability of the cut ingot 100 is improved, the pressure of the cut ingot 100 is reduced, and the surface damage of the ingot 100 is prevented.

A protection assembly 323 is arranged between the connecting seat and the lifting shaft 3212 and/or the guide shaft 3222, a protection cavity 3234 in the protection assembly 323 is used for being connected with an external air source, and the protection cavity 3234 is filled with air pressure through the external air source to prevent liquid from entering the shaft core through a protection ring 3232; meanwhile, lubricating oil can be injected into the shaft core through the air passage to lubricate the shaft core, so that the service life of the shaft core is prolonged.
