The invention belongs to the field of rubber, and specifically discloses a rubber vulcanization method and a rubber production method. The rubber vulcanization method includes placing the compounded rubber in the mold cavity, closing the mold, and raising the temperature in the mold cavity to the vulcanization temperature to carry out the vulcanization reaction, wherein, the method also includes before closing the mold. Water is sprayed on the surface of the rubber compound and / or the mold cavity, and during the vulcanization process, the vulcanization temperature is controlled to not be lower than the gasification temperature of water in the mold cavity. Using the method provided by the invention to vulcanize rubber not only greatly improves the yield of vulcanized rubber products, but also can significantly reduce the cleaning frequency of molds and reduce production costs.

The invention discloses a compact single-axis scanning device for a laser cleaning machine, and relates to the technical field of laser cleaning. The compact single-axis scanning device of the laser cleaning machine includes a splint, the upper end of the splint is installed with an upper clip for docking and installing on the inner side of the laser cleaning machine, and the lower end of the splint is installed for clamping and installing on the laser cleaning machine. For the lower clip on the inner side, the bottom of the splint is equipped with a connecting plate, the connecting plate is in the shape of a ring, and an intermediate plate is installed on the upper end of the connecting plate, and the splint is connected to a The first-order shrapnel is movable and installed, and the tangent line between the clip and the rod ring can be the central axis, and the splint is turned to the outside. Under the continuous pressing and fitting of the wide push ring on the upper part of the splint, the inner side of the first-order shrapnel is effectively lifted up.

The invention relates to the field of maintenance of steel equipment, in particular to a quick lifting method for online drawing a rotor of a large motor. The quick lifting method comprises the steps as follows: dismantling a cardan shaft of the motor; dismantling an upper tile of a bearing base of the motor, an outer cover of the motor and a foundation bolt of a stator of the motor; dismantling an encoder of the motor and a thrust bearing. The quick lifting method is characterized in that a lifting beam of the rotor is lifted by a traveling crane and arranged at the top of the stator of the motor; chain blocks and steel cables are hung at the two ends of the lifting beam of the rotor; the rotor of the motor is lifted through the chain blocks, and is not contacted with the interior of the stator of the motor; electric hydraulic jacks are erected at the four corners of the stator of the motor and used for synchronously lifting the stator of the motor and the rotor, fixed through the lifting beam of the rotor, of the motor; when the electric hydraulic jacks are lifted to the lowest position of the rotor of the motor beyond the plane of the bearing base, the lifting beam of the rotor is lifted by the traveling crane, and the rotor of the motor is drawn out. The quick lifting method can quickly and safely lift the large motor and finish the rotor drawing operation, and overcomes the defects in the traditional large motor lifting operation.
