Key Features

Body: Main body use Q345B steel and main big parts are with welded structure, in order to make sure the quality of welding, those big parts will be processed with annealing treatment to eliminate welding deformation and stress, positioned block has been used in the joint surface between the lower platen, column, beam to prevent dislocation to guarantee the precision of installation; Four tie bar has been pre-tightened by hydraulic force, slide use eight side guiding system to reach the advantage of high adjustable precision, good rigidity. Besides, the guiding system use wear resistant bronze material, it has good wear resistance and long life use.

Cylinder: Main cylinder body use whole parts 45# quality forged steel as well as piston and plunger, surface with hardening treating, hardness can reach HRC45 or more. Seals use imported components to guarantee the sealing.

Lubrication device: Slider and hydraulic cushion rail adopt centralized intermittent oil lubrication system, it has lubricating oil level indicator and filter clogging alarm function, you can set the lubrication time on the touch screen.

Hydraulic System: The machine is equipped with the oil filtration system, when operate the machine, this system automatically circulate the oil tank filter to clean the oil; the pump and motor group and hydraulic control valve has been placed on the surface of the oil tank, main pump and motor group use horizontal installation method. At the bottom of the tank, pump inlet is equipped with a permanent magnet, remain the impurities on the permanent magnet, reducing hydraulic system failure.

Oil Tank: it is mounted on the top: tank disposed on the side of the upper platen, it has oil indicator, and with oil clogging alarm system.

Noise: According to DIN EN ISO 11202 stds measured in 1 m distance form operator working position on a height of 1.6 m for a time of 90 s.

Painting: As per customer’s requirement.

CE-Norm: This offer is for the supply of machine according to Directives 2006/42/EC and its amendments.

The advantage of ZHENGXI Hydraulic System

1) The hydraulic control system of the equipment is mainly arranged on the right side of the fuselage with neat appearance and convenient maintenance. Hydraulic system is composed of oil tank, hydraulic main control system, pump station, pressure gauge, filter and other accessories. It is mainly connected to the whole hydraulic control system through pipeline.

2) The hydraulic system of this machine mainly adopts the advantages of servo closed-loop control, hydraulic oil temperature control and double support protection control.

3) The fuel tank is arranged on the right side of the fuselage. It is mainly used to supply oil and heat dissipation of hydraulic oil for the driving elements of the whole equipment and to fill the cylinder quickly when the slider goes down rapidly. The oil tank is steel plate welded by mixed gas, which reduces welding slag and is designed as a closed structure. Pickling, passivation and rust-proof treatment are carried out during tank installation. Industrial flour dough is used to clean up again before shipment to ensure that there are no residues and debris on the inner wall. The fuel tank panel is equipped with a return tank to facilitate the recovery of waste oil.

4) The side of the tank is provided with a manhole for cleaning the window cover of the tank to facilitate the cleaning of the tank. The tank passes through a special oil injection hole, and the bottom of the tank is also equipped with magnets to absorb impurities in the oil. The bottom of the tank is slightly inclined and equipped with an oil drain valve. The tank is welded with steel plate. Before assembly, pickling, passivation, rust-proof treatment and leak-proof test should be carried out.

5) The tank is equipped with a level gauge (with temperature display) on the side, which is convenient for observation when refueling.

6) The tank is equipped with an independent oil filter with a filtering accuracy of 10 microns. Equipped with plugging alarm device of filter element of oil filter to remind replacement of filter element. The oil tank is connected with the outside world through the air filter to ensure that the hydraulic oil is not polluted by the outside world. The filtering accuracy of air filter is 20 micron.

7) The main oil pump and servo motor are arranged orderly on the oil tank. The high-pressure pump adopts high-quality high-pressure internal meshing gear pump. The internal meshing gear pump has the advantages of low noise, energy saving, high-pressure stability and small heat output.

8) The main hydraulic control system of the equipment adopts the cartridge integrated valve produced by Shandong Jining Taifeng Company, which is installed on the thickened tank panel and connects the valve parts, instruments and pumps through high-pressure pipelines. The cartridge type integrated valve is characterized by compact structure, sensitive and reliable action, strong anti-pollution ability, small liquid flow resistance, convenient maintenance and long service life. The structure of two-way cartridge valve mainly consists of cartridge parts, control cover plate, pilot control valve and integrated valve block, and slide valve structure.

9) In the hydraulic system of this machine, there are pressure detection points in key parts. Pressure of each part is measured by pressure gauge and pressure sensor. Pressure gauge is directly in the form of pointer system. Pressure sensor is reflected by analog quantity to PLC through touch screen display. The fault of hydraulic press can be quickly diagnosed and the working state of hydraulic press can be monitored through the pressure detection point.

10) The type of hydraulic oil used in this machine system is L-HM46# anti-wear hydraulic oil (Party B provides the first injection).

11) Hydraulic tubing is made of c
