Hydraulic press is a kind of mechanical equipment that uses hydraulic system to produce strong force, which is often used in the stamping process of metal materials. Its working principle is to convert hydraulic oil into mechanical energy through the hydraulic cylinder, and drive the punch to work.
The hydraulic press is mainly composed of frame, chassis, cylinder, head, upper die, lower die, hydraulic pump station and electrical system. The hydraulic pump station provides hydraulic oil and controls the lift of the cylinder through the hydraulic control system. When the hydraulic oil enters the cylinder, the hydraulic oil in the cylinder is subjected to pressure, pushing the indenter to move downward, so that the material between the upper die and the lower die is subjected to a strong force. In this way, the metal material can be stamped into the desired shape. During the working process, the hydraulic oil returns to the hydraulic pump station through the oil return port to complete a working cycle.
The application range of hydraulic press is very wide, can be used for metal stamping, die parts, lathe parts of cutting, pressing, stretching, double die, hydraulic bending, powder stamping and other processes.
1. Metal stamping: The hydraulic press can be used for punching, drawing, forming and other stamping processes of metal materials, such as the production of auto parts.
2. Mold processing: The hydraulic press has large pressure and high reliability, which is suitable for the processing of large molds. It can be stamped out of various shapes of metal parts by changing the shape and size of the bottom die.
3. Sheet metal processing: hydraulic punch can be used to process a variety of complex sheet metal parts, such as electrical boxes, mechanical shells, aviation parts and so on.
4. Sheet processing: The hydraulic press has a large workbench area and can process sheet materials of larger sizes, such as furniture metal finishing stamping.
5. Powder stamping: The hydraulic press can be used for cold stamping in the powder metallurgy process, and the metal powder is formed into various complex shapes by stamping.
6. Hydraulic bending: The hydraulic press can achieve bending of metal materials by changing the shape of the bottom die and the upper die.
In general, the hydraulic press has the characteristics of high pressure, good stability, high power and strong adaptability, and is widely used in stamping, mold manufacturing, auto parts, hardware products, home appliance manufacturing and other industries. At the same time, with the development of science and technology, the degree of automation of the hydraulic press is also constantly improving, making the production efficiency higher and the quality more stable.
