The invention discloses a combined method of arc ion plating and twin target bipolar high-power pulsed magnetron sputtering, and belongs to the technical field of material surface treatment. The method aims to solve the problem of large particles due to use of low-melting-point pure metal (like aluminum) or multicomponent alloy materials and non-metallic materials (like graphite) in arc ion plating and the limitation of semiconductor material silicon, and discharge arcing in the unipolar high-power pulsed magnetron sputtering technique and the limit in using of high-melting-point and difficult-to-ionize target materials (like zirconium) are eliminated. The method includes the steps that first, workpieces are placed on a sample table inside a vacuum chamber and connected with related equipment; second, thin film deposition is performed, working gas is introduced when vacuumizing is executed to 10<-4> Pa, and a film coating power supply is switched on; and the large-particle defect in arc ion plating is overcome through high-power pulsed magnetron sputtering, the high-melting-point and difficult-to-ionize materials are ionized through arc ion plating, twin targets generate multi-component plasma and further adjust the content of the plasma in a thin film, plasma energy is regulated through a grid bias power supply, and accordingly the thin film can be prepared.

The invention discloses a harmonic drive cam. According to the characteristic curve of the cam, low-angular-frequency and high-angular-frequency cosine waves are added on the basis of a cosine function, a low-angular-frequency cosine term is used for reducing the trend that a radius vector of the long axis of the cam becomes smaller, a high-angular-frequency cosine term is used for changing the deformation amount of the short axis of the cam, and the deformation amount of the long axis of the cam is smaller than that of the short axis of the cam. According to the harmonic drive cam, the comprehensive performance of harmonic drive is improved, the harmonic drive wrap angle can be increased through the characteristic curve of the harmonic drive cam, and the harmonic drive bearing capacity is improved.

The invention discloses a hydraulic power device of a dual-axis shearing type crusher, relates to the technical field of hydraulic power systems, and aims to solve the problem that an existing hydraulic power system is not beneficial for heat dissipation and maintenance, and is easily polluted. According to the technical scheme, the key point is that the hydraulic power device comprises a closed type hydraulic station and an external pipeline, wherein a hydraulic motor is connected to the closed type hydraulic station through an external pipeline; the closed type hydraulic station comprises acabinet type box body with a plurality of shutters on four side walls, a square tube beam, and an oil tank assembly, wherein an air cooler is mounted on the top of the cabinet type box body, the square tube beam is arranged on the middle part of the cabinet type box body for dividing the cabinet type box body into an upper box body and a lower box body from top to bottom; the oil tank assembly isborne on the square tube beam, and is positioned in the upper box body; and a motor pump group, an energy accumulator group and a flushing valve group are arranged in the lower box body. The motor pump group comprises a motor, a main pump and a gear pump, the main pump and the gear pump are positioned below the oil tank assembly, and the motor is positioned at one side of the oil tank assembly. The hydraulic power device facilitates heat dissipation and maintenance, and has a dustproof function.

The invention discloses a binding machine. The binding machine comprises a driving part, a transmission part, a binding part and a shearing part. The transmission part is driven by the driving part, and binding and shearing of a binding wire are completed through forward and reverse rotation of the transmission part; the binding part is in transmission connection with the transmission part, and inthe binding part, the binding wire is wound to form a binding coil; and the shearing part comprises a shearing transmission part and a shearing knife which are in transmission connection with the transmission part, and the shearing knife is driven by the shearing transmission part to shear off the binding coil from the binding wire. The binding part can quickly bind plant vines, and the arrangedbinding part can change the conveying path of the binding wire, so that the binding wire used for binding can be automatically wound to form a hanging ring shape to be wound on the surfaces of the vines, and binding is achieved; the binding efficiency is improved, and the labor intensity is reduced; and the arranged shearing part can be used for quickly shearing the binding wire, so that the working efficiency is improved, and the situation that scissors or other sharp edges are manually taken for shearing in the traditional process is avoided.
