The method comprises the following steps of carrying out special steel wire rod defect identification and determining the sampling part and a sampling mode. According to the on-line inspection confirmation method, the defect type and the defect part of the special steel wire rod are identified, so that the influence of defects on a roller on a finished product is reduced to the maximum extent, and the surface quality of the special steel wire rod is improved.

The invention relates to an automobile interior trim part slush molding bed which comprises a lifting mechanism, a horizontal conveying mechanism and a turnover mechanism. The automobile interior trim part slush molding bed is characterized in that the turnover mechanism comprises a turnover frame, a powder box automatic locking mechanism installed on the turnover frame and a mold automatic locking mechanism of a self-locking structure. The automobile interior trim part slush molding bed has the advantages that a mold and a powder box do not need to be manually locked, the locking speed is high, self locking is achieved through the self structure in the mold locking process, and it is ensured that the mold is not disengaged from the turnover frame.

The invention discloses a manufacturing method of an isolation board for sintering. The method comprises the following steps of: 1, preparing polyvinyl alcohol or cellulose into an aqueous solution, adding metal oxide powder and stirring uniformly to obtain slurry; 2, uniformly coating slurry on one or two faces of a metal board with a flat surface; and 3, putting the slurry-coated metal board into a drying oven for drying to obtain the isolation board for sintering. The manufacturing method has the advantages of simple procedures, low cost and high production efficiency. The manufactured isolation board for sintering can be used repeatedly. After the isolation board is used, organic matters are volatilized, oxide powder particles fall, and slurry can be repainted on the recycled metal board after soot cleaning, so that an isolation board for sintering is manufactured for repeated use. The isolation board for sintering manufactured with the method is taken as an isolation layer between laminated plate blanks, so that sintering adhesion of the plate blanks can be prevented effectively, the surfaces of the plate blanks are protected, and the surface quality of the sintering plate blanks is not influenced simultaneously.

The invention discloses an automatic control method of a counting stacking machine and belongs to the field of automatic mechanical equipment. The method includes the steps that a driving cylinder ofa material distributing mechanism drives a material receiving plate to be folded, and material receiving is prepared; metal blades fall onto the material receiving plate and are received and positioned; the driving cylinder drives the material receiving plate to be opened, the metal blades fall onto a conveying mechanism, and meanwhile counting is performed; the material receiving plate is foldedagain, the steps are repeated so that the metal blades can be overlaid and stacked on a conveying mechanism; when stacking is performed till a set number is achieved, the conveying mechanism drives the stacked metal blades to move forwards by certain distance and then stops; and the operation is repeated so that a row of stacked metal blades can be obtained on the conveying mechanism, and the counting and stacking operation of the metal blades is completed. The automatic control method of the counting stacking machine can be used for stacking the blades, automatic operation is achieved, counting is accurate, efficiency is high, manual intervention is avoided, the blades are not damaged, and the safety is high.

The invention provides an ultra-large diameter all-welded ball valve sealing structure. The ultra-large diameter all-welded ball valve sealing structure comprises a ball, a ball pad, a ball pad base and a connecting pipe which are sequentially connected from interior to exterior. The face, attached to the ball, of the ball pad is provided with a first slope and a second slope which are tangent to the ball, and the position, tangent to the ball, of the first slope is located above the position, tangent to the ball, of the second slope.
