The main features of thefour-column hydraulic press machineand how to choose
What we want to share today is the main purpose of the four-column hydraulic press. The hydraulic press manufacturer analyzes it from a professional point of view. Which forming products are mainly used for the four-column hydraulic press, the following content is easy to understand. Please continue to look down,
Four-column hydraulic press is suitable for limit technology of plastic materials. Such as powder product molding, plastic product molding, cold (hot) kneading metal molding, sheet stretching, transverse pressing, bending pressing, turning through, editing and other technologies.
It has an independent power mechanism and electrical system, centralized control by buttons, and can complete three modes of operation: adjustment, manual and semi-active.
Principle: The oil pump delivers the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper or lower chamber of the cylinder through various check valves and relief valves. Under the action of high pressure oil, the cylinder moves.
A hydraulic press is a device that uses liquid to transmit pressure. When a liquid transmits pressure in a closed container, it obeys Pascal’s law. The hydraulic transmission system of thefour-column hydraulic press machineconsists of a power mechanism, a control mechanism, an executive mechanism, an auxiliary mechanism and a working medium. The power mechanism usually uses the oil pump as the power mechanism, and usually uses the refined oil pump as the power mechanism. In order to meet the needs of the execution speed of organizational activities, choose one oil pump or multiple oil pumps. Centralized control via individual buttons. It has two modes of operation: adjustment and one-handed rotation.
The integrated system of cartridge valve can be used for hydraulic control, which is firm, has long service life, and has small hydraulic shock, which reduces the connection pipes and leakage points, or is usually hydraulically controlled. The hydraulic press has wide versatility and is suitable for various plastic materials. Kneading, forced bending, hemming, stretching and other processing molding; can also be used for limited molding of various plastic and powder products. In addition, it can also be used for finishing, pressing and forming of finished products.
315 tons of four-column hydraulic press
The 315-tonfour-column hydraulic press machineis suitable for metal drawing, bending, flanging, cold extrusion, blanking and other processes, and is also suitable for straightening, pressing, powder making, etc.
Products, abrasive products compression molding and plastic products, insulating materials compression molding.
315 tons of four-column hydraulic press
Advantages: The large effective area of the worktable can meet the processing requirements of various large workpieces. Compared with the traditional stamping process, the work is stable and the impact force is small.
The manufacturing process is to stamp and form two half pieces first, and then weld them into a whole, while thefour-column hydraulic press machineforms the workpiece at one time during the hydraulic process, reducing subsequent machining and
The amount of welding in the assembly reduces the weight of the workpiece, reduces the number of parts, improves the strength and stiffness, especially the fatigue strength, and realizes the advanced manufacturing of lightweight and high-strength structures.
manufacturing technology.
Features of 315 ton four-column hydraulic press:
1 Computer-optimized structural design, three-beam four-column structure, simple, economical and practical.
- The hydraulic control adopts the integrated system control of the cartridge valve, which has reliable action, long service life, small hydraulic shock, and reduces the side pipeline and leakage points.
3 Independent electrical control system, reliable action, intuitive, easy maintenance
4 Adopt button centralized control, with two operation modes: adjustment and manual single cycle
5 Through the selection of the operation panel, two molding processes of fixed stroke and fixed pressure can be realized, and there are functions such as pressure holding delay, and the working pressure stroke can be adjusted within the specified range according to the process needs.
How to choose the column of the four-column hydraulic press?
There are many customers who order four-column hydraulic presses, mainly because of high cost performance, easy to find accessories, and convenient maintenance. However, there are accessories for a column, and the probability of use is very high. There must be some requirements when choosing a column. The following analysis will be described in more detail, please take the time to read it.
The column of thefour-column hydraulic press machineis a very important part of the hydraulic press. If the choice is not good, it will cause damage to the beam. A series of unfavorable conditions that affect the work of the hydraulic press will follow. So this time, we will briefly introduce the first step of the four-column hydraulic press, which is dip dyeing, and then users can refer to our instructions to buy suitable products when purchasing columns, so as to avoid adverse effects on the hydraulic press.
Here we take a small tonnagefour-column hydraulic press machineas an example. Under normal circumstances, the small-tonnagefour-column hydraulic press machinewill cause considerable damage to the column in the case of frequent urban comparisons. Therefore, when choosing a hydraulic press, the column is also a small-tonnage four-column hydraulic press. The advantages that other hydraulic presses cannot match, such as high working frequency, The body has low rigidity and fast running speed.
Therefore, when choosing the column of the hydraulic press, be sure to stabilize the following aspects. First, the repetitive tensile stress must be excessive. Repeated loads should be calculated. The high-intensity repetitive stress of the single-column hydraulic press will produce cracks, followed by the load and centrifugal force being the largest. The damage of the column will not be suddenly forcibly broken. After being repeatedly stressed for hundreds of thousands of times, a crack occurs and then the crack expands.
