What are the characteristics of the hydraulic press
First, the characteristics of hydraulic press
1. The stroke speed of the movable beam of the hydraulic press depends on the characteristics and use of the hydraulic press of the pump, and has nothing to do with the deformation resistance of the forgings in the process. If the characteristics and uses of the hydraulic press of the pump are the characteristics and uses of the normal hydraulic press, the working speed of the hydraulic press is the characteristics and uses of the fixed hydraulic press.
2. The hydraulic supply pressure and power consumption of the pump are related to the deformation resistance of the workpiece to be processed. The working deformation resistance is large, and the hydraulic supply pressure and power consumption of the pump are also large, and vice versa.
3. The characteristics of the constant travel speed of the movable beam and the change of the hydraulic pressure of the pump can be used as the signal for operating the distributor to realize the automatic control of the hydraulic press.
4. The basic investment is low, the floor area is small, and the daily maintenance and maintenance are simple. The hydraulic pumps in the pump direct drive system are selected according to the maximum working speed and working pressure of the hydraulic press, and the hydraulic pump cannot be fully utilized when the hydraulic press has a small filling stroke, return stroke, auxiliary process and required working pressure, especially It is a hydraulic press with the characteristics and uses of a large hydraulic press, and its utilization coefficient is very low. Therefore, the hydraulic press tends to transmit the working speed and working pressure in stages.
Features and uses of hydraulic presses
Second, the classification of hydraulic presses
Hydraulic presses are classified by structure
Now it is mainly divided into: four-column hydraulic press (three-beam four-column type, five-beam four-column type), double-column hydraulic press, single-column hydraulic press (C-shaped structure), frame hydraulic press, etc.
Classification by use of hydraulic presses
Mainly divided into metal forming hydraulic press, bending hydraulic press, stretching hydraulic press, punching hydraulic press, powder (metal, non-metal) forming hydraulic press, press-fitting hydraulic press, extrusion hydraulic press, extrusion molding, etc.
Third, the use of hydraulic press
It is widely used in the processing of spare parts in the automotive industry and the shaping, edge punching, correction of various products in various industries, and the pressing, embossing and forming of shoe-making, handbags, rubber, molds, shafts, and bushings. Bending, embossing, sleeve stretching and other processes, washing machines, electric motors, automobile motors, air-conditioning motors, micro motors, servo motors, wheel manufacturing, shock absorbers, motorcycles and machinery industries.
