The application discloses a high-precision rolling and expanding method for an asymmetric outer double-groove machine case ring forging and a product. The method comprises the following steps: firstly, carrying out multi-pass special-shaped section rolling and expanding after rolling on a rectangular cross-section ring blank to obtain an asymmetric outer double-groove ring forging; and then carrying out afterheat expanding on the asymmetric outer double-groove ring forging after heat treatment to obtain a final ring forging. For the forming process of the asymmetric outer double-groove ring forging, the number of special-shaped section rolling, the number of expanding, the expanding amount of the afterheat expanding process, the expanding amount after each pass of special-shaped section rolling, and the outer diameter of the special-shaped section ring forging after each pass of special-shaped section rolling are designed and calculated in advance, so that the size difference of the axial two end faces of the final ring forging and the ovality are reduced. The rolling process of the asymmetric outer double-groove machine case ring forging is carried out in steps, the size end problem is eliminated, and the ovality of the final machine case ring forging can be ensured to be within 0.1% of the outer diameter size.

The application relates to a beating machine for corrugated paperboard production, which comprises a tank body with a chamber in the inside, an inner cylinder is arranged in the chamber, a plurality of through holes are formed in the inner cylinder, a pulping crushing chamber is arranged in the inside of the inner cylinder, and a buffer chamber for storing paper pulp is formed in the outside of the inner cylinder by the inner cylinder; two fly cutter rollers are arranged in the inside of the buffer chamber and rotate oppositely, a driving element is arranged above the tank body, and a circulating unit is further arranged on the tank body; the beating machine can make the paper pulp in the buffer chamber return to the crushing chamber for circulating crushing for multiple times through cooperation of the driving element, the fly cutter rollers and the circulating unit, different raw materials with different particle sizes continuously receive the cutting action of the fly cutter rollers in the multiple circulating processes, the size difference of the raw material particles is effectively reduced, and the uniformity of the paper pulp is remarkably improved.

The present application belongs to the technical field of titanium alloy forging, and relates to a die forging method of a special-shaped titanium alloy nozzle shell. In view of the problems of low material utilization, low processing efficiency and damaged metal streamline in the prior art, the present application proposes to integrate the pre-forging and finish-forging dies into an integrated multi-cavity die, thereby simplifying the forging process. The specific steps include designing and processing the die, preheating the die, heating the bar and forging the pre-forging piece, transferring the pre-forging piece to the finish-forging die to forge the formed piece, and then performing surface treatment, heat treatment and machining. The present application can improve the material utilization, save the production cost, ensure the stable product performance, simplify the process flow, reduce the labor intensity and cost of workers, and has a wide application prospect.

The embodiment of the invention provides a driving method of a display panel and the display panel, the display panel is provided with a display area and a light-transmitting area, the display panel comprises data lines and a plurality of pixel circuits arranged in an array, and each column of pixel circuits is connected with one data line. The number of the pixel circuits connected with the data lines corresponding to the light-transmitting area is smaller than that of the pixel circuits correspondingly connected with the data lines corresponding to the display area, and the pixel circuits are located in the display area; the driving method comprises the steps that in a display period, preset data voltage is transmitted to at least part of column data lines corresponding to at least part of row scanning periods in a light-transmitting area; wherein at least part of the lines include the last line of pixels corresponding to the light-transmitting area, and the preset data voltage is non-black state voltage. According to the scheme, the problem that a bright line extending upwards is generated at the junction of the light-transmitting area and the display area is effectively solved, and the display effect is further improved.
