Q:What are tensile and shrink wrapping?: Stretching: one of the basic characteristics. The tensile feature is to draw the cross section of the drawn cross section in a specified tensile direction at a specified depth. Stretching is the most commonly used entity creation type that is suitable for creating rule entities and should be skilled.The main purpose: contraction of envelope: complex parts or components 1. can be used as a reference or package model to create a lightweight version; 2. can be used to create geometric model sharing relationship with suppliers and customers, and get rid of what you don't want to share details; file - save a copy - type contraction envelope; create components, in the form of a activation element inserts - shared data - shrinkwrap -- referring to the type for the components of a subset of context.

Q:Mechanical structure and principle of automatic focusing lens for camera: Ultrasonic ranging method, which is based on the ultrasonic wave in the digital camera and the time between the subject of distance measurement. Digital cameras are equipped with ultrasonic transmitting and receiving device, when the ultrasonic vibration generator for ultrasonic, ultrasonic to the subject, is the receiver's perception of return immediately, and then by the integrated circuit according to the ultrasonic round-trip time to calculate the focusing distance.

Q:The working principle of the bolt tensioner: During operation, the high-pressure oil output by the power source is conveyed to the piston cylinder 3 by a high-pressure hose, and the piston in the piston cylinder moves upward under the action of pressure to drive the stretching nut upwards. The nut and bolt tensile work thread, thereby stretching the working bolt, the bolt elongation reached the required amount of deformation, deformation control in the elastic deformation range, then the pre tightening or disassembling operation, finally through the hydraulic or mechanical return the work bolt return to its original shape, finish the homework.

Q:Mechanical principle of belt expansion machine: Conveyor sections: two, three, four. Width of conveyor belt: 500, 600, 700, 800, 1000, 1200mm. Belt conveyor speed can be selected: constant or variable speed. Belt conveyor direction can be selected: one-way or two-way conveying materials. Belt conveyor angle can be selected: horizontal, fixed angle or automatic lifting. The fixed section of the conveyor can be fixed or fixed. Conveying speed: <30 M / min.. Conveyor capacity: <70 kg / m..

Q:What is a bolt tensioner? How do you use it?: Bolt tensioner is a bolt hydraulic stretcher with hydraulic booster pump (super high pressure hydraulic pump hydraulic source) provided, according to the tensile strength, yield tensile and elongation coefficient determined, using ultra high pressure pump the stretch, the bolt is applied force in the elastic deformation zone is stretched, bolt the diameter of slight deformation, so that the nut is easy to loose, and it can be used as a hydraulic interference connection device of applied axial force, top pressure installation. The biggest advantages of stretcher can make a plurality of bolts and fixed value fastening and disassembly, uniform force distribution, is a safe, efficient and fast tool is the best way to bolt fastening and disassembly of various specifications. Used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. According to different working conditions, application conditions and user requirements, it can be used as a special stretcher design.

Q:How to achieve telescopic power arm: Consider synchronous motor, screw drive, photoelectric induction limit, PLC connection drive control displacement

Q:What are the main uses of a bolt tensioner?: Stretch, fasten, or loosen the bolts and think of the bolts as a rubber band,

Q:What are the main uses of a bolt tensioner?: Stretch, fasten, or loosen the bolt and think of the bolt as a rubber band. It is flexible and can be stretched freely within its range of elastic deformation

Q:What kind of materials are used in the telescopic equipment of machinery industry?: The most common form of bond failure is shear. So the key requires enough strength and steel. No. 45 is the most commonly used steel.

Q:How do you pull the contracted muscles with a mechanical device?: Muscle cramps occur in swimming is not surprising in panic, self-help is not water side hand cramps cramp toes, forced to pull the body, at the same time with the side of the hand hold the leg cramps cramp knee, knee extension to help relieve spasm, after, and then slowly toward the shore. < < excerpt > > (Mo Fei) the method of dealing with muscle spasm during exercise. The main causes of muscle spasm are: 1. A great deal of dehydration in the training competition, which results in imbalance of the body's dielectric.
