The blank 1 is placed in a flattening machine for flattening so that the warp of the blank 1 is less than 0.2mm, as shown in fig. 2.
In step S2, a plurality of semi-finished parts 2 are machined on the first side of the blank 1 by a CNC machine, the semi-finished parts 2 are uniformly arranged, so that the first ends of the semi-finished parts 2 are independently separated, and the second ends of the semi-finished parts 2 are connected together by the connecting portion 5.
During processing, enough rim charge 3 is reserved between the edge of the blank 1 and the closest row of semi-finished parts 2, and a connecting part 5 with the thickness of more than or equal to 0.3mm is reserved between the second end of each semi-finished part 2 and the bottom of the blank 1 so as to ensure the connection stability between the semi-finished parts 2, as shown in fig. 3 and 4.
Then, step S3 is executed to clean the semi-finished part 2.
And cleaning the whole plate blank 1 to remove the residual scraps and oil stains on the blank 1, and after the cleaning is finished, cooling the blank 1 to room temperature to perform the next procedure.
In step S4, a binder 4 is filled in the first side of the blank 1, the binder 4 comprising landplaster, an antifoaming agent and water, the landplaster being preferably anhydrite in this embodiment, and the antifoaming agent being preferably a gypsum antifoaming agent.
The preparation method of the adhesive 4 comprises the following steps:
(1) Preparing gypsum powder, water and a defoaming agent according to the proportion requirement, wherein the proportion of the gypsum powder to the water is 100:30, and the defoaming agent accounts for 1-3 per mill of the total weight of a concoction of the gypsum powder and the water;
(2) Pouring all the defoaming agent into water and stirring uniformly;
(3) Slowly pouring the mixed solution of the defoaming agent and the water into the gypsum powder, adding the mixture and stirring the mixture until the mixture is uniformly stirred, wherein the stirring time needs to be controlled within 1 minute;
(4) The prepared fluid adhesive 4 is uniformly filled in the first side of the blank 1, and the surface is scraped by a hardboard, so that the surface of the adhesive 4 is about 0.3mm to 0.5mm higher than the blank 1, or each part semi-finished product 2 cannot be seen visually, as shown in fig. 5.
then, step S5 is executed to perform defoaming and curing processes including:
and putting the blank 1 filled with the binder 4 into a vacuum box for vacuum-pumping treatment, wherein the negative pressure value in the cavity is kept between 0.08 and 0.1MPa, and the keeping time is 15 to 20 seconds.
After defoaming treatment, a vacuum suction clamp is adopted to suck the blank 1 and keep the first side surface of the blank 1 horizontally upward, then the blank is kept standing for 30-35 min under the environment that the temperature is more than or equal to 20 ℃ and the air humidity is less than or equal to 80 percent, so that the binder 4 is dehydrated and solidified, the main component of the gypsum powder is CaSO 4 4 and reacts with water to generate CaSO 4.2H 2 O, the CaSO 4.2H 2 O is gradually solidified into hard blocks after losing water in the air, all the semi-finished parts 2 and the rim charge 3 are bonded together to form a whole, the semi-finished parts 2 are conveniently clamped for subsequent processing, meanwhile, no damage is caused to the semi-finished parts 2, and burrs can be effectively prevented from being generated at the edges of the semi-finished parts during processing.
In step S6, the first end face of the semi-finished part 2 is milled.
Specifically, after the binder 4 is cured, the back surface of the blank 1, i.e., the second side surface, is adsorbed on the corresponding vacuum fixture, and an end mill with a diameter of 100mm is used to mill off 0.15 mm-0.2 mm of the whole surface of the first side of the blank 1, so that the first end faces of all the semi-finished parts 2 can be milled in the process. Then, finishing the workpiece, controlling the cutting depth within 0.01-0.015 mm and the cutting speed at 600mm/min to obtain good surface quality and avoid accumulating burrs, as shown in figures 6 and 7.
In step S7, the second side of the blank 1 is milled.
Specifically, the blank 1 is cleaned with compressed air, and then the blank 1 is sucked by a vacuum suction jig and the second side surface of the blank 1 is kept horizontally upward. And (3) milling the connecting parts 5 on the second side of the blank 1 by using an end mill with the diameter of 100mm to ensure that the second ends of all the part semi-finished products 2 are not directly connected, and then finishing the end surfaces of the second ends of all the part semi-finished products 2 to ensure that the thickness tolerance of all the part semi-finished products 2 is controlled within +/-0.015 mm, as shown in fig. 8 and 9.
Then, step S8 is executed to separate the slabs.
Specifically, all the semi-finished parts 2 in the blank 1 are separated into a plurality of first fragments together with the binder 4, the size of the first fragments is controlled within 5 mm-8 mm, namely, each first fragment contains about four semi-finished parts 2, as shown in fig. 10.
Subsequently, step S9 is executed to perform the immersion softening process.
4 2 4 2 4 2Putting all the first fragments into a sodium carbonate solution with the concentration of 20%, soaking for a first preset time, and stirring once every second preset time in the soaking process, wherein the first preset time is preferably 1H, and the second preset time is preferably 2H.
Then, step S10 is executed to perform the dissolution separation process.
Further breaking the first fragment into second fragments, the size of the second fragments being smaller than the size of the first fragments; in the process, workers need to wear silica gel protective gloves to prevent skin from being burnt.
and putting the second fragment into diluted hydrochloric acid with the proportioning concentration of 1mol/L, and soaking for a third preset time until the binder 4 is dissolved. In the process, calcium carbonate remained on the surface of the semi-finished part 2 reacts with diluted hydrochloric acid to generate calcium chloride, water and carbon dioxide which are easy to dissolve in water, so that the binder 4 is separated from the semi-finished part 2, and the binder 4 is prevented from being attached to the surface of the semi-finished part 2.
subsequently, step S11 is executed to execute the flushing screening process.
and after the binder 4 is dissolved, putting the second fragments in a fine filter screen, washing with clear water, screening out all the semi-finished parts 2, completely separating the semi-finished parts 2 from the binder 4, and finally, leaving the finished parts.
generally, after confirming that the finished part is free of impurities, step S12 is performed to clean the finished part to ensure the surface quality of the part.
