Embodiment 1

[0024] A large-size potassium dihydrogen phosphate crystal cutting and fixing equipment is remanufactured by using an industrial magnetic lifter; a 300-600kg magnetic lifter is selected, and a steel plate is vertically fixed on one side of the magnetic lifter, and 6 pieces are evenly installed on the steel plate screw.

[0025] The thickness of the steel plate is 5-10mm, the height is 250-400mm, and the width is 10-250mm.

[0026] A method for preventing large-size potassium dihydrogen phosphate crystal forming blanks from fragmenting, the specific method steps are as follows:

[0027] 1) Place the KDP crystal to be cut in a cutting machine room with a relatively constant temperature, and the indoor temperature difference between day and night is ±1°C, and place it for 7-10 days;

[0028] 2) Place the crystal to be cut on the backing plate, and place a 3-5mm rubber cushion or 10-30mm foam between the crystal and the backing plate;

[0029] 3) Use the magnetic force of the ma...

Embodiment 2

[0037] The method for cutting fixtures and preventing the fragmentation of the molded blank is the same as in Example 1, the difference is that:

[0038] 8 screw rods are evenly installed on the steel plate of the cutting fixture.

[0039] In the method for preventing the fragmentation of the formed blank, step 4) uses the small contact surface of the screw on the cutting and fixing device to contact the crystal to fix the crystal; in step 5), the upper and lower edges of the blank to be cut do not affect the formation of the blank. Adhesive with glass strips.

Embodiment 3

[0041] The method for cutting fixtures and preventing the fragmentation of the molded blank is the same as in Example 1, the difference is that:

[0042] 12 screw rods are evenly installed on the steel plate of the cutting fixture.

[0043] In the method for preventing the fragmentation of the formed blank, step 4) uses the small contact surface of the screw on the cutting and fixing device to contact the crystal to fix the crystal; in step 5), the upper and lower edges of the blank to be cut do not affect the formation of the blank. Adhesive with hacksaw blades.

Abstract

The invention relates to a large size potassium dihydrogen phosphate crystal cutting fixed equipment and a method for preventing the fragmentation of forming billet tablets, which belongs to the technical field of processing artificial crystal materials. The cutting fixed equipment is remanufactured by using an industrial magnetic lifting jack; the method for preventing the fragmentation of forming billet tablets is that before cutting, a KDP crystal to be cut is arranged in a cutting machine chamber with a relative constant temperature, the diurnal temperature in the chamber is plus or minus 1 DEG C, and the KDP crystal is placed for 7-10 days; the crystal to be cut is put on a backing plate, the cutting fixed equipment is fixed on a cutting machine stage to fix the backing plate; a screw on the cutting fixed equipment is used for being contacted on the crystal through a plurality of points or a small contact surface, thus the crystal is fixed and the angle of the crystal is adjusted; a rubber pad and a baffle are arranged at one side of the forming billet tablet to be cut, the baffle is fixed on the stage, and the upper and the lower edges of the forming billet tablet to be cut where the billet tablet forming is not affected are pasted with an organic glass strip, a glass strip and a hacksaw blade; when the cutting is finished, the forming billet tablets are taken out safely and the futile parts are cut off. The large size potassium dihydrogen phosphate crystal cutting fixed equipment and the method for preventing the fragmentation of forming billet tablets of the invention can solve the problems of crystal fixing and easy fragmentation of the forming billet tablet.

Description

technical field [0001] The invention relates to cutting and fixing equipment for large-size potassium dihydrogen phosphate crystals and a method for preventing fragmentation of molded blanks, and belongs to the technical field of artificial crystal material processing. Background technique [0002] Since the international community signed the Nuclear Test Ban Treaty, Western powers have been investing heavily in the development of inertial confinement fusion (ICF) projects in order to improve nuclear weapons and possibly produce controlled nuclear fusion devices to obtain huge and "clean" energy , This is a major project reflecting the comprehensive national strength. In the ICF project, large-scale high-quality potassium dihydrogen phosphate (KDP) and dide-deuterium potassium phosphate (DKDP) crystals are important materials for frequency doubling devices and electro-optic devices in high-power laser drivers; in the field of nuclear explosion simulation technology at home a...
