The application discloses an aluminum magnesium manganese color-coated aluminum plate processing and cutting device, and relates to the technical field of cutting devices.The device comprises a conveying frame, a mounting plate, a downward pressing and stretching component comprising a rotating rod, a deflection rod, a stretching roller and an inclined rolling assembly, a cutting and scrap removing component comprising a gas supply cylinder, a suction cylinder and a translation conveying assembly, and a roller pressing and leveling component.The stretching roller is rolled and stretched by the inclined rolling assembly during cutting, the suction cylinder is used to suck scrap by the translation conveying assembly, and the roller pressing and leveling component is used for leveling.The aluminum magnesium manganese color-coated aluminum plate processing and cutting device can drive the two stretching rollers to roll reversely when cutting the aluminum plate, can apply continuous stretching force to the two sides of the cut to inhibit deformation, and can automatically separate the cut after cutting;the suction cylinder can suck high-temperature aluminum scrap and dust in time to avoid hot melting and adhesion;the pressing roller can cooperate with the stretching roller and the conveying roller to press and level the plate near the cut during separation, can form a micro chamfer, and can improve the processing quality.

The application discloses a stamping equipment with a knife edge wear prevention function, and relates to the technical field of stamping machine tools.The stamping equipment comprises a feeding machine, an electric control cabinet, a punch mechanism and a bottom die mechanism, the feeding machine, the electric control cabinet and the punch mechanism are fixedly connected with the bottom die mechanism, and the electric control cabinet is connected with the punch mechanism through electric signals.The punch mechanism comprises a driving mechanism, an assembling frame and a cutter mechanism, the driving mechanism comprises a sliding block, the cutter mechanism comprises a base plate, and the assembling frame is fixedly connected with the sliding block and the base plate.The application realizes rapid approach of a stamping cutter to materials, improves stamping efficiency, stamps materials at a low speed, reduces instantaneous impact force on a knife edge, reduces micro-chipping, performs cyclic liquid cooling on the cutter, effectively controls the working temperature of the knife edge, prevents hardness reduction and thermal fatigue wear caused by excessively high temperature rise, forms a lubricating oil film between the knife edge and metal sheet raw materials, slows down the rigid collision between the knife edge and the metal sheet, and reduces knife edge wear.

The application discloses a blanking die and a blanking process for an ultrathin steel strip, and relates to the technical field of metal precision stamping. The die comprises a punch, a die and a back pressure ejection device arranged in the die. The punch has a center region of a material pressing body and a periphery of a die body, the material pressing surface of the material pressing body has a preset height difference Ah from the blade edge end surface of the die body; and the supporting surface of the back pressure ejection device is flush with the die blade edge plane in the initial state. During blanking, the material pressing body of the punch first contacts the material to be cut and presses the material to be cut on the supporting piece to move downward by a distance Ah, so that the "pre-stretching" is realized before the material is sheared; then, the blade edge of the die body cooperates with the die to complete the blanking. Through the "center pressing and periphery cutting" mode, the stress distribution in the material is effectively improved, the warping deformation is fundamentally inhibited, and the flatness of the material to be cut of the ultrathin steel strip and the cross section quality are significantly improved.

The invention provides a screen printing plate processing method for improving the performance of a heterojunction solar cell. The screen printing plate processing method comprises the following steps: preparing a super-hydrophobic ionic liquid / silicon dioxide / polyimide composite coating solution; preparing a super-hydrophobic ionic liquid / silicon dioxide / polyimide composite coating solution; coating the coating solution on a scraper surface of a screen printing plate, and drying; coating the film coating solution on the printing surface of a screen printing plate, attaching a film to the printing surface of the screen printing plate, and performing ultraviolet irradiation curing; after curing, the film is taken away, the printing face is washed with water, the needed pattern is formed, and the screen printing plate is manufactured. According to the method, a layer of super-hydrophobic ionic liquid / silicon dioxide / polyimide composite film is adhered to the tensioned screen, so that the performance of the screen is effectively improved, the adhesiveness of the slurry and the screen is reduced, and the use amount of the slurry is greatly reduced during printing.

The present invention relates to the technical field of hydraulic shears, and discloses an integral tool holder with an L-shaped connection structure, comprising a hanging plate, the bottom end of the hanging plate is fixedly connected to a main frame, the side of the main frame is fixedly connected to a feed port, the bottom end of the main frame is fixedly connected to a hydraulic cylinder, the middle part of the top end of the hydraulic cylinder is fixedly connected to a push rod, the top end of the push rod is fixedly connected to a connecting tool holder, and the top end of the push rod is set to be "L"-shaped; the present invention adopts an "L"-shaped connection structure of a specific size between the connecting tool holder and the push rod by providing a push rod, a connecting tool holder, a lower blade, and a fixing bolt, and the "L"-shaped connection can better ensure the stability of the connection between the cylinder and the tool holder under high impact, and the force stability during the shearing process is increased. At the same time, because the new structure is simpler and stronger than the traditional tool holder, the service life of the cylinder will be greatly improved, and the cross-sectional quality of the sheared steel billet will also be better.
