Description

Technical Field

[0001] The invention relates to the field of quartz plate processing, and more specifically to a circular quartz plate orifice plate fine sintering method. Background Art

[0002] At present, quartz orifice plates are often processed by two methods: fine firing from the inner circle to the outside, or first firing small holes from the outside and then fine firing from the outer diameter to the inner diameter. Among them, the product is prone to deformation when fine firing is carried out from the inner circle to the outside. If the orifice plate has small hole characteristics, it will easily crack from the small hole position. When first firing small holes from the outside and then fine firing from the outer diameter to the inner diameter, the probability of cracking is significantly reduced, but there is still a large deformation in size. The above two methods of fine firing of quartz orifice plates have their own disadvantages, and both have the problem of high loss rate. Summary of the invention

[0003] In order to overcome the above problems, the present invention provides a method for fine-firing a quartz plate, which can reduce the probability of cracking and dimensional deformation at the small holes in the quartz plate, thereby improving the success rate of fine-firing the quartz plate.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a perforated plate sintering method, comprising the following steps:

[0005] Step a: fix the circular quartz orifice plate on the workbench by a positioning fixture for fine firing;

[0006] Step b: according to the characteristics of the small holes on the surface of the circular quartz orifice plate and the position characteristics of the circumferential array arrangement, the orifice plate is equidistantly arranged into a number of firing stations, and a small flamethrower is used to sequentially perform fine firing around the small holes in the firing stations, and the corresponding positions on the reverse side are also fine fired in the same manner;

[0007] Step c: Use a collective spray gun to fine-fire the small hole position in the firing station that has completed the fine-firing in step b, and fine-fire the corresponding position on the reverse side in the same way;

[0008] Step d: Use a collective spray gun to fine-fire the circular quartz orifice plate that has been fine-fired in step b from the center to the outer diameter, and fine-fire the corresponding position on the reverse side in the same way;

[0009] Step d: The other firing stations of the circular quartz plate are also finely fired in the same manner as in steps b, c and d.

[0010] The present invention provides a method for fine-firing a hole plate, which is an improvement on two original fine-firing processing schemes for circular quartz hole plates, namely, fine-firing by expanding the inner circle to the outside or first burning small holes from the outside and then fine-firing from the outer diameter to the inner diameter. The processing scheme can reduce the probability of cracking of the circular quartz hole plate due to the position of the small holes and dimensional deformation during the fine-firing process, thereby improving the yield of the circular quartz hole plate. A further optimization scheme of this scheme is as follows: Step b is further optimized: according to the characteristics of the small holes on the surface of the circular quartz orifice plate and the position characteristics of the circumferential array setting, the orifice plate is equidistantly arranged into a number of firing stations, and the several firing stations are equally divided into four equally divided arc areas of A, B, C, and D. Area A is 0°~90°, area B is 90°~180°, area C is 180°~270°, and area D is 270°~0°. Then, a small flamethrower is used to perform fine firing in sequence around the small holes in the 0° firing station in area A, and the corresponding position on the opposite side is also fine fired in the same way; Step c: Use a collective spray gun to perform fine firing on the small hole position in the firing station that has completed the fine firing in step b, and the corresponding position on the opposite side is also fine fired in the same way ; Step d is further optimized: use a collective spray gun to fine-fire the circular quartz orifice plate that has completed the fine-firing in step b from the center to the outer diameter, and first fine-fire half of the firing station, and then fine-fire the corresponding position on the opposite side in the same way; then fine-fire the remaining part of the front side, and then fine-fire the corresponding position on the opposite side in the same way; Step e is further optimized: rotate the circular quartz orifice plate to 90°, and perform the fine-firing operations of steps b, step c and step d again; rotate the circular quartz orifice plate to 30°, and perform the fine-firing operations of steps b, step c and step d again; rotate the circular quartz orifice plate to 60°, and perform the fine-firing operations of steps b, step c and step d again; thereby achieving the fine-firing of the circular quartz orifice plate in area A. B area sintering process: rotate the circular quartz orifice plate to 180°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate to 120°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate to 150°, and perform the sintering operations of step b, step c and step d again. C area sintering process: rotate the circular quartz orifice plate to 270°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate to 210°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate to 240°, and perform the sintering operations of step b, step c and step d again. D area fine firing process: rotate the circular quartz orifice plate to 300°, and perform the fine firing operations of step b, step c and step d again; rotate the circular quartz orifice plate to 330°, and perform the fine firing operations of step b, step c and step d again.The above steps can finally realize the fine firing of the circular quartz orifice plate.

[0060] Step b: Step b is further optimized: according to the characteristics of the small holes 101 on the surface of the circular quartz orifice plate 100 and the position characteristics of the circumferential array setting, the circular quartz orifice plate 100 is equidistantly arranged into a plurality of firing stations 102 in the circumferential direction, and the plurality of firing stations 102 are equally divided into four equally divided arc regions of A, B, C, and D, wherein the A region is 0° to 90°, the B region is 90° to 180°, the C region is 180° to 270°, and the D region is 270° to 0°. Then, a small flamethrower is used to sequentially perform fine firing on the small holes 101 in the 0° firing station 102 in the A region, and the corresponding positions on the reverse side are also fine fired in the same manner. The four small flamethrowers 401 are started, and then the first motor 412 is started. The first motor 412 is started to drive the first gear 413.

[0062] Step d: Step d is further optimized: the circular quartz orifice plate 100 that has completed the fine firing in step b is finely fired from the center to the outer diameter using the collective spray gun 402. The fine firing first fires half of the firing station 102, and the corresponding position on the reverse side is also finely fired in the same way; then the remaining part of the front side is finely fired, and then the corresponding position on the reverse side is also finely fired in the same way; in this step, different areas of the same firing station 102 can be fired simultaneously by four collective spray guns 402, and at the same time, the first The second motor 418 rotates to drive the screw rod 419 to rotate, and the screw rod 419 rotates to drive the threaded sleeve 420 to slide along the slide groove 429, thereby driving the connecting arm 405 to move the circular quartz orifice plate 100 from the center to the outer diameter direction to perform fine firing.

Fine-firing process of area B: the circular quartz orifice plate is rotated to a 180° position, and the fine-firing operations of step b, step c and step d are performed again; the circular quartz orifice plate 100 is rotated to a 120° position, and the fine-firing operations of step b, step c and step d are performed again; the circular quartz orifice plate 100 is rotated to a 150° position, and the fine-firing operations of step b, step c and step d are performed again. C area sintering process: rotate the circular quartz orifice plate 100 to 270°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate 100 to 210°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate 100 to 240°, and perform the sintering operations of step b, step c and step d again. D area sintering process: rotate the circular quartz orifice plate 100 to 300°, and perform the sintering operations of step b, step c and step d again; rotate the circular quartz orifice plate 100 to 330°, and perform the sintering operations of step b, step c and step d again; wherein, the circular quartz orifice plate 100 is adjusted in angle by rotating the adjusting device 416, first adjusting the piston cylinder 201 to shrink the clamping plate by a certain distance, and then starting the third motor 422, the third motor 422 rotates to drive the roller group 423 to drive, thereby driving the circular quartz orifice plate 100 to perform precise angle adjustment. The above steps can finally achieve fine firing of the circular quartz orifice plate 100. This process is relatively cumbersome, and common manual firing is prone to omissions or uneven firing of the circular quartz orifice plate 100, thereby affecting the fine firing quality of the circular quartz orifice plate 100. Therefore, this solution can perform fine firing operations through a controller combined with a mechanical device.
