Hydraulic presses and hydraulic presses are two common types of presses in the mechanical industry. There are some differences in principle, structure and application. The differences between hydraulic presses and hydraulic presses will be discussed in detail below.
1. Principle:
Hydraulic presses and hydraulic presses work differently. The hydraulic press generates pressure in the seal cylinder through hydraulic oil, drives the piston downward movement, and then drives the stamping mechanism to complete the stamping work. The hydraulic punch directly drives the mechanical rod through the hydraulic cylinder to produce a downward impact force and complete the stamping work.
2. Structure:
Hydraulic presses and hydraulic presses are also different in structure. The hydraulic press is generally composed of motor, oil pump, flow control valve, governor, hydraulic cylinder, connecting rod and other components. Hydraulic press is mainly composed of motor, oil pump, direction control valve, pressure control valve, hydraulic cylinder and so on.
3. Functions:
Hydraulic presses and hydraulic presses differ in function. Hydraulic punching machine is mainly used for metal material punching, punching, drawing, forming and other processes. Hydraulic presses are more suitable for the punching of large-size metal workpieces, such as automotive body panels, large containers, etc.
4. Control mode:
Hydraulic presses and hydraulic presses are also different in the control mode. The hydraulic press is generally controlled by hand or foot, and the operation is relatively simple. The hydraulic press is controlled by electric control or PLC, which can realize automatic production and improve work efficiency.
5. Accuracy:
The machining accuracy of hydraulic presses and hydraulic presses is also different. Because the working principle of the hydraulic punch is more simple and direct, its processing accuracy is relatively high. Because of the sealing and control accuracy of the hydraulic valve, the machining accuracy of the hydraulic press is relatively low.
6. Energy utilization:
There are also some differences in energy utilization between hydraulic presses and hydraulic presses. Because of the large energy loss, the energy utilization efficiency of hydraulic press is low. The hydraulic press can use the pressure oil flowing in the system to recover and reuse, and realize the recycling of energy.
7. Maintenance:
Hydraulic presses and hydraulic presses are also different in terms of maintenance. The hydraulic press needs to replace or add hydraulic oil regularly, clean the hydraulic system, and keep the system running normally. The hydraulic press needs to regularly check the tightness and oil leakage of the hydraulic system to ensure the stable operation of the system.
In summary, there are some differences between hydraulic presses and hydraulic presses in terms of working principle, structure, function, control mode, processing accuracy, energy utilization and maintenance. Selecting the right type of press requires consideration of specific processing requirements and production needs to meet the required stamping process.
