As an important equipment for the production of hydraulic presses in the automation industry, for some foreign manufacturers, how to choose hydraulic presses has become a matter of great concern to them.As long as you fully understand the process requirements of the products you make, and know the fixing method and dimensions of the mold, it is not difficult to choose the right hydraulic press. In fact, the basic things you need to pay attention to when choosing a hydraulic press are tonnage, Table size, stroke, opening height, etc.
(1)Pressure:
The pressure of the selected product is better choose the 10%-90% of the range of the machine.
(2)Opening height:
It is the height of the press head from the work surface when it is located at the upper dead point; it is also called the mold opening height, which is the upper dead point of the press; it is also used with the closed height and the stroke to determine the opening height of the press. The closed height is the lower dead point of the press, and the stroke is the opening height; for a unified understanding, we call the opening height；
(3)Press-fit stroke:
The distance from the upper dead point to the lower dead point of the press head；
(4)The worktable size(Max upload capacity):
It is appropriate to install the mold and place the workpiece conveniently；
(5)Mold installation mode:
Fixed mode at the upper and lower ends (generally, the mold handle is used at the upper end, and the T-slot is opened on the countertop below for installation)
The hydraulic press adopts the principle of Pascal’s Law. It uses the power of fluid to operate.
Usually, the hydraulic press will contain three important parts: the machine, the power source and the hydraulic control unit. Shanghai Antis brings you the following four common types and applications.
1. Four-column hydraulic press：
Four-column hydraulic presses are used in precision tool applications.The drawing, bending, flanging, correction, press-fitting, hot and cold extrusion of metal materials are also suitable for the drawing, bending, flanging, cold extrusion and blanking of metal materials.The four-column universal hydraulic press is also suitable for the correction, press-fitting, powder products, abrasive products, press-forming and press-forming of plastic products and insulating materials.According to user needs, it can be equipped with digital display of stroke, digital display of pressure and other functions.It has the advantages of easy operation, fast installation and maintenance, and low cost.
2. Single-column hydraulic press：
The fuselage of the single-column hydraulic press is a C-type single-arm structure, so the single-column hydraulic press is also called a C-type rack hydraulic press.The hydraulic system is located in the fuselage, with a beautiful appearance and easy operation.The single-column hydraulic press has the characteristics of good structural rigidity, good guiding performance, and fast speed.。C-type rack hydraulic presses can be used in the automotive, electronics, household and medical industries, and can be used for sheet metal forming, plastic forming, bending, deep punching and other applications.The C-type rack hydraulic press saves space due to its small size.
3. Horizontal hydraulic press：
The horizontal hydraulic press has an independent power mechanism and electrical system, and adopts button centralized control. It can realize three working methods: adjustment, manual and semi-automatic: the working pressure of the machine, the pressing speed, the stroke and range of no-load fast descent and deceleration can be adjusted according to the needs of the process, and the ejection process can be completed. There are three process methods: ejection process and stretching process. Each process is a constant pressure and a fixed range. Two process actions are available, and the constant pressure forming process has an ejection delay and automatic return after pressing.The height of the workbench can be adjusted according to the comfort of the workers.
4.Two-column hydraulic press：
Computer-optimized structural design, three-beam and two-column structure, simple, economical and practical.The hydraulic control adopts an integrated system of cartridge valves, which has reliable operation, long service life and low hydraulic impact.The connecting pipeline and leakage point are reduced.Good electrical control system, reliable work, intuitive operation, easy maintenance.It adopts button centralized control, with adjustment, and two modes of operation in a single cycle with both hands.Through the selection of the operation panel, the two forming processes of fixed range and constant pressure can be realized, and they have the properties of holding pressure delay.The working pressure and stroke are adjustable within the specified range according to the needs of the process.Double-column hydraulic presses are suitable for major, medium and small enterprises, factories, industrial mines and auto repair shops.
