Structural Characteristics of Hydraulic Press Machine

图片
The  hydraulic press machine  consists of two parts: the main engine and the control mechanism. The main part of the hydraulic press machine includes the fuselage, the main cylinder, the ejector cylinder and the liquid filling device. The power mechanism consists of a fuel tank, a high-pressure pump, a low-pressure control system, an electric motor, and various pressure valves and directional valves. Under the control of the electrical device, the power mechanism realizes the conversion, adjustment and delivery of energy through pumps, oil cylinders and various hydraulic valves, and completes the cycle of various technological actions. The  hydraulic press machine  directly driven by the hydraulic press pump has the following characteristics 1. The stroke speed of the movable beam of the hydraulic press depends on the liquid supply of the pump, and has nothing to do with the deformation resistance of the forging in the process. If the liquid supply of the pump is constant, the working

Features of metal  cold  extrusion  hydraulic press 1. Double speed, double motor, wide application range and high efficiency. 2. The frame and movable table have high precision, good rigid

Operation of Hydraulic Sheet Metal Drawing Press

图片
The operation of  hydraulic sheet metal drawing press : adjustment and single cycle, which are converted with a transfer switch. There are two working modes of the press: constant pressure forming and fixed stroke forming. The constant pressure forming process action has the functions of pressure holding delay and automatic return. Adjustment: jogging, an intermittent action proportional to the length of time the button is pressed, and the action stops when the button is released. In the adjusted working mode, there is a micro-motion matching function: press the down button, the upper chamber of the main cylinder of the slider does not pressurize, the slider is under the control of the throttle valve without pressure and slowly micro-moves down, and the hand is released to stop. It is used when aligning molds and molds.                                                   Single cycle: A single cycle of the slider operation: After the initial conditions and safety conditions are met, pres

Status and Trend of Hydraulic Press Machine Development

With the rapid development of China's manufacturing industry, the processing accuracy of parts is also getting higher and higher. Some forged parts with complex shapes and high accuracy requirements, especially forges that are difficult to process with machine tools or high costs. They must not be processed without processing. Perform precise forging directly under the premise. The  hydraulic press machine  is studied on the basis of absorbing Western advanced experience and technology. Today, with the increasingly developed technology power, the performance of the hydraulic press machine is gradually increasing. It provides convenience and creates greater economic and social benefits. Due to the wide range of applications and stable performance of the hydraulic press, it is necessary to achieve a variety of processes only needed to replace the mold. It is a rare advanced mechanical and equipment, saving investment costs, and has been well received by investors. At present, China&#

Hydraulic Sheet Metal Drawing Press

  Hydraulic sheet metal drawing press is also called metal sheet stretching machine. Stretching hydraulic press, automobile cover stretching hydraulic press, auto parts stretching hydraulic press, fan casing stretching hydraulic press, ash bucket truck stretching hydraulic press, teacup cover stretching forming machine, metal special-shaped parts stretching hydraulic press, etc. The four-column hydraulic press for sheet metal stretching is a commonly used model. It adopts a three-beam four-column structure. The fuselage consists of an upper beam, a sliding beam, a workbench, a hydraulic backing plate, a mandrel, an oil cylinder, a column, a liquid filling tank, and a limit mechanism. . Sheet metal stretching hydraulic press, metal sheet stretching machine 200 tons, 315 tons, 400 tons, 800 tons. The system adopts servo system control, and the stretching pressure, speed and displacement precision are well controlled to ensure that the stretched products are highly consistent. The equipme

Servo Hydraulic Press Improves Performance and Save Energy

图片
The   servo hydraulic press  is in the general hydraulic press and the direction control circuit, while the AC servo hydraulic press plus the quantitative oil pump is composed of a controllable hydraulic source, instead of the ordinary induction motor to drive the uncontrollable hydraulic source, combined with various sensors, through the motor control, to achieve the pressure of the energy-saving system, position, speed control. The servo hydraulic press adds displacement sensors to the main cylinder and auxiliary cylinder, and enters the hydraulic pressure sensor in the main cylinder to realize position, speed, pressure, and closed-loop control. Servo hydraulic presses  improve performance and save energy 1. Operational errors of common sense. For example, the three phases are reversed, the fuel tank is not enough, and the pressure regulating valve has no friends to increase the pressure. This usually comes up on newbies in the press. 2. Insufficient power supply. It usually appears

Punch presses are also called open tilting presses and are also a branch of hydraulic presses. However, there are also certain differences between   hydraulic presses   and punch presses. Hydraulic presses are also called presses or hydraulic presses, which mainly use hydraulic oil medium, hydraulic cylinders and electrical systems to cooperate with each other through certain molds to press products. The following is an explanation of the difference between a   hydraulic press   and a punch. 1. Detailed description of the characteristics of the hydraulic press In modern machining, the productivity requirements are low, and the blanking of small and medium-sized parts is generally carried out by hydraulic presses, and the production cycle is generally not more than half an hour. According to the size of the workpiece to be processed, the pressure load (centering or eccentric) and the forming method, the structure of the press is determined as a single-column hydraulic press with a C-sha
