2results about How to "Accuracy requirements met" patented technology

The application relates to a positioning and mounting method of a continuous casting machine casting nozzle, which comprises the following steps: S1, centering adjustment device setting; S2, positioning device setting; S3, box body mounting and adjustment; S4, substitute module mounting; S5, refractory one-time pouring; S6, nozzle plate mounting; S7, refractory secondary pouring; the application takes the positioning device as a positioning reference, aligns the long side of the cross-shaped groove in the middle of the positioning device with the transverse center line of the continuous casting machine, aligns the short side of the cross-shaped groove in the middle of the positioning device with the casting flow center line of the continuous casting machine, adjusts the horizontal position of the box body through a horizontal jackscrew device, makes the position of the box body meet the accuracy requirement of the positioning device, carries out one-time pouring layer construction and preliminary positioning of the nozzle plate through the substitute module, and then accurately controls the accuracy of the nozzle plate and the positioning device through the cross-shaped scale, so that high-precision positioning of the box body, the nozzle plate and the control line of the continuous casting machine is finally realized.

This invention relates to the field of machining technology, and particularly to an intelligent matching method and system for slow wire EDM machining parameters. The method involves loading electrode wire parameters and workpiece parameters to configure machining parameters and obtain first machining parameters. When the monitored environmental parameters are inconsistent with the standard environmental parameters, the method uses the electrode wire parameters, workpiece parameters, first machining parameters, and monitored environmental parameters as constraints to search the slow wire EDM machining sample set, performs lumped value evaluation, and obtains the fitted dimensions of the workpiece after cutting. When the dimensional deviation between the fitted dimensions and the standard dimensions of the workpiece after cutting is less than or equal to the dimensional tolerance, metal cutting control is performed based on the first machining parameters; otherwise, the first machining parameters are updated. This invention improves the accuracy and stability of metal cutting using slow wire EDM, reduces trial cutting costs and scrap rates, increases machining efficiency, and reduces production burden.
