FAQ

The design principle of Pneumatic machine is to convert the circular motion into linear motion, by the force of the main motor, drive the flywheel, drive the clutch gear, crankshaft (or eccentric gear), connecting rod operation, to achieve the linear motion of the slider, the motion from the main motor to the connecting rod is circular motion. Between the connecting rod and the slider, there need to be a connection point of circular motion and linear motion. There are roughly two kinds of mechanisms in the design, one for the ball type and the other for the pin type (cylindrical type). The circular motion is converted into the linear motion of the slider by this mechanism.

Pneumatic punching machine exerts pressure on the material, so that its plastic deformation, and obtain the required shape and accuracy, so it must be matched with a group of molds (divided into upper and lower die), the material placed in the middle of the machine to exert pressure, deformation, processing force caused by the force on the material, Absorbed by the punch machine body.

The design principle of Stamping Press is to convert the circular motion into linear motion, drive the flywheel by the output of the main motor, drive the gear, crankshaft (or eccentric gear), connecting rod and so on through the clutch to achieve the linear motion of the slider, and the motion from the main motor to the connecting rod is circular motion.

There should be a transfer point of circular and linear motion between the connecting rod and the slider. There are roughly two kinds of mechanisms in the design, one is ball type and the other is pin type (cylinder type). The circular motion is converted into the linear motion of the slider through this mechanism. The punch applies pressure to the material, so that the plastic deformation, and obtain the required shape and accuracy, so it must be matched with a group of die (divided into upper die and lower die), the material is placed in the middle, by the machine to exert pressure, make its deformation, processing force on the material caused by the reaction force, by the punch mechanical body absorbed.

C-Frame Hydraulic Fast Press is a device that uses liquid to transfer pressure. Liquids follow PASCAL’s law when transferring pressure in a closed container.

The Hydraulic transmission system of C-Frame Hydraulic Fast Press is composed of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism and a working medium.

The power mechanism usually uses the oil pump as the power mechanism, which is generally a positive displacement oil pump. In order to meet the requirements of the movement speed of the actuator, one oil pump or more oil pumps are selected. Low pressure (oil pressure is less than 2.5MP) with gear pump; Medium pressure (oil pressure less than 6.3MP) with vane pump; High pressure (oil pressure less than 32.0MP) with plunger pump.

C-Frame Hydraulic Fast Press usually refers to hydraulic pump and hydraulic motor. Hydraulic pump and hydraulic motor are energy conversion devices in hydraulic system. The difference is that hydraulic pump converts the mechanical energy of driving motor into the pressure energy of oil, which is a power device in hydraulic system. And hydraulic motor is to convert the pressure energy of oil into mechanical energy, is the implementation device in the hydraulic system.

The hydraulic pump and hydraulic motor commonly used in the hydraulic system are volumetric, and its working principle is to use the change of sealing volume for oil absorption and oil pressure. From the working principle, most of the hydraulic pump and hydraulic motor is reciprocal, that is, the input pressure oil, hydraulic pump into hydraulic motor, can output speed and torque, but in the structure, hydraulic pump and hydraulic motor or some differences.

C-Frame Hydraulic Fast Press has an independent power mechanism and electrical system, and adopts button centralized control, which can realize three working modes of adjustment, manual and semi-automatic. The working pressure and pressing speed of the machine, as well as the stroke and range of no-load fast descending and deceleration can be adjusted according to the process needs. And can complete the ejection process with ejection process, drawing process three process modes, each process is constant pressure, fixed range two process action for choice, constant pressure molding process after pressing with ejection delay and automatic return. Single column hydraulic press has a wide range of versatility, suitable for a variety of plastic materials processing and forming, such as extrusion, bending, folding, stretching, etc., while the hydraulic press can also be used for a variety of plastic, powder products extrusion forming. In addition, the single column hydraulic press can also be used for product correction, pressing and shaping.

The hydraulic transmission system of Four column hydraulic press is composed of a power mechanism, a control mechanism, an actuator, an auxiliary mechanism, and a working medium. The power mechanism usually uses the oil pump as the power mechanism, which is generally the product oil pump. In order to meet the requirements of the movement speed of the actuator, one oil pump or more oil pumps are selected. Low pressure (oil pressure is less than 2.5MP) with gear pump; Medium pressure (oil pressure less than 6.3MP) with vane pump; High pressure (oil pressure less than 32.0MP) with plunger pump. The pressure processing and forming of various plastic materials, such as the extrusion, bending, stretching of stainless steel plate and cold pressing of metal parts, can also be used for powder products, grinding wheels, bakelite, resin thermosetting products.
