Q & A
What’s hydraulic press machine?
Hydraulic press is a kind of metal forming machine which uses liquid as working medium and is made according to Pascal principle to transfer energy and realize various processes.
The hydraulic press is not only used for forging, but also for straightening, pressing, packing, pressing block and pressing plate. It is widely used in the pressing processing and forming of various plastic materials, such as the extrusion, bending, drawing of stainless steel plate and the cold pressing forming of metal parts. It can also be used in the pressing of powder products, grinding wheel, bakelite, resin thermosetting products, etc.
The basic principle is that the oil pump transmits the hydraulic oil to the integrated cartridge valve block, and distributes the hydraulic oil to the upper cavity or the lower cavity of the oil cylinder through each one-way valve and overflow valve, so as to make the oil cylinder move under the action of high pressure oil. In order to meet the requirements of the moving speed of the actuator, one or more oil pumps are selected. Gear pump for low pressure (oil pressure less than 2.5MP); vane pump for medium pressure (oil pressure less than 6.3mp); plunger pump for high pressure (oil pressure less than 32.0mp).
The hydraulic press consists of the main engine and the power mechanism. The main part of the hydraulic press includes the main body, the main cylinder press, the ejecting cylinder and the filling device. The power mechanism consists of oil tank, high-pressure pump, low-pressure control system, motor, various pressure valves and directional valves. Under the control of the electric device, the power mechanism realizes the energy conversion, regulation and transmission through the pump, oil cylinder and various hydraulic valves, and the hydraulic press completes the circulation of various process actions.
The specification of hydraulic press is generally expressed by nominal working force (KN) or nominal tonnage (T).
The biggest characteristic of the hydraulic press is that it is pressed average flat, economical and can be widely used.
Types of hydraulic press machine?
According to the type of liquid transmitting pressure, can be divided into oil hydraulic press and water hydraulic press
According to the direction of force, can be divided into vertical and horizontal
According to the operation mode, can be divided into manual and electric
According to the control mode, can be divided into CNC and general
According to the structure, can be divided into four column type, single column type (C type), double column type, horizontal type, vertical frame (gantry H frame), universal hydraulic press, etc
According to application, can be divided into metal forming, bending, stretching, punching, powder (metal, non-metal) forming, pressing, extrusion, etc
According to the processing technology, can be divided into powder forming hydraulic press, automobile heavy beam hydraulic press, non-metallic special hydraulic press, mechanical repair hydraulic press, carbon product hydraulic press, plastic product hydraulic press, ceramic product hydraulic press, etc
According to the tonnage, can be divided into 1 ton, 5 tons, 10 tons, 50 tons, 63 tons, 100 tons, 200 tons, 315 tons, 500 tons, 1000 tons, 3000 tons, etc. Any pressure tonnage can be set according to the customer’s requirements.
Application of hydraulic press machine
Automotive, aerospace and home appliances industries
It is mainly used for forming all kinds of metal devices, including stamping, drawing, and forming processes of metal covering parts, metal sheet parts, and other metal devices. In this field, the function of a hydraulic press is irreplaceable, and it is the necessary machinery of this kind of industry.
Processing of small and medium-sized mechanical parts
It is often used for small and medium-sized metal mechanical parts in various industries involving metal devices. Including extrusion forming, die pressing forming, cold and hot die forging and stamping as well as the free forging of metal profiles.
Powder products industry
The industry needs to achieve large pressure in a small space to enable powder products to be processed, so the advantages of the hydraulic press are very obvious, and its stability and pressure make powder products more possible. For example, powder metallurgy and magnetic materials.
Pressing and forming of non-metallic materials
The pressing of non-metallic materials belongs to the process of manufacturing of specific products. For example, SMC molding, hot pressing molding of automobile interior parts and processing of rubber products, etc.
Hot pressing technology of wood products
This field fully embodies the characteristics of the hydraulic press, which can not only process hard metal products but also complete the production of flexible products. For example, the hot processing technology of profiles and the processing of plant fiber plates, and so on.
Other applications
The application of hydraulic press in other fields, more obvious processes such as plastic sealing, press fitting, correction, and stamping, etc.
Our 300 ton hydraulic press adopts computer-optimized design, simple structure, economical and practical. What is the 300 ton hydraulic press made of? Is the quality reliable? Take 300 tons three-beam four-column hydraulic press as an example, the machine is composed of two parts: the mainframe and the control mechanism, through the main pipe and electrical devices connected to form a whole. The mainframe includes fuselage, main oil cylinder, buffer oil cylinder, and liquid filling system, etc. Three beams are welded with a Q235A steel plate, and a high-temperature annealing treatment is adopted to eliminate welding stress. T-grooves are arranged on the lower surface of the middle beam and the surface of the worktable to facilitate the installation and replacement of molds. The material of the cylinder body is 45# forged steel of high quality to ensure uniform material; All piston rod surfaces are quenched. Use imported sealing rings (such as Taiwan Dingzing, Japan NOK), reliable sealing, no leakage. The electric control system is composed of an electric cabinet and button box. the button and signal lamp are made of a domestic famous brand. The hydraulic valve station is usually arranged on the right side of the main engine. The hydraulic system adopts an advanced cartridge integrated valve system. This valve flow, anti-pollution, flexible control, reliable performance, easy maintenance. The oil tank is welded from a Q235A steel plate, which is installed with an oil level indicator, air filter, and so on. Pickling, passivation, and anti-rust treatment should be carried out when the oil tank is installed. The oil filter device is equipped to ensure the cleanliness of the working oil. The trial operation will be carried out before the delivery of the 300-ton hydraulic press to ensure that everything is normal before the machine is allowed to leave the factory. Every process has been strictly controlled.
How to maintain and operate 300 tons hydraulic press?
Please read the instruction carefully before use. Familiar with machine structure and operation procedure. We have the following suggestions for machine maintenance and safe operation:
1. Anti-wear hydraulic oil of 32 # -46 # is recommended for working oil. Should be based on the temperature: room temperature below 20℃, available 46 # hydraulic oil. When the room temperature is higher than 30℃, 32 # can be used. The oil temperature should be in the range of 15℃ to 60℃.
2. The oil should be strictly filtered before it is allowed to be added to the oil tank. The amount of oil in the oil tank should not be lower than the oil mark, and the filling tank should also be added to the oil mark.
3. The working oil should be replaced once a year, and the first time should not exceed three months.
4. The slider should be regularly lubricated, the column appearance should always be kept clean, and the oil should be sprayed before each work.
5. Calibrate and check the pressure gauge every six months
6. When the machine is not used for a long time, the processing surface should be scrubbed clean and coated with anti-rust oil.
