Hydraulic press machine
A hydraulic press is a multifunctional machine with strong generality: press fitting of shaft components and axle sleeves, coining and overprinting, and pressing powder and plastic products where requirements are not strict. Eight standard models, 10 to 250 tons, button control as standard and PLC as an option.
What this machine is
KECMT Hydraulic Press is a kind of multifunctional machine which has strong generality. It is suitable for the press fitting of shaft components and axle sleeve parts as well as the movements of coining and overprinting. It can also be used to press powder and plastic products which the requirements are not strict. At the same time, it mainly applies to the fields of machine tool, engineering machinery, electrical components, bearings, washing machine, automobile parts and motor components. It can even be used as an assembly line.
Main advantages
- Energy saving, high speed, low noise
- Pressure, stroke and pressure-maintaining time all regulated
- Integral two-way plug-in valve block — fast response, large oil-passing capacity, small flow resistance, reliable operation, easy maintenance
Standard and optional fitment
- Light curtain safety device (optional)
- Button panel controller
- Optional PLC program controller
- Stroke and speed digital control device
- Cooler device, displacement sensor
- Constant stroke / constant pressure exchange
Hydraulic press system
The hydraulic transmission device of the machine is arranged beside the hydraulic press machine, and its role is to control the movement of the slider. The hydraulic control system adopts the integral two-way plug-in valve integrated block. It has fast response speed, large oil-passing capacity, small flow resistance, reliable operation and easy maintenance. The power device of the cartridge valve uses a large-flow CY high-pressure variable axial piston pump. The large-diameter pipes of the hydraulic system are connected by flange joints, which are shockproof and leak-proof. The hydraulic oil tank is equipped with an oil filter device and a liquid level display device, and the filling tank is installed on the upper end of the upper beam.
Component details
- Oil pump (updated from YCY to HY): nine plungers, high oil supply density, more stable flow — greatly reducing micro-crawling of the cylinder piston, suitable for fine work, especially metal drawing where the forming effect is better
- Hard pipe: the pressure line is connected by hard pipe — neat and beautiful, reduces impact on the pipeline, and makes spillage more difficult
- Combination gasket: all oil joints sealed with a combination of gaskets — rubber internally, customised red copper externally; the ductility of red copper makes the bond tight and effectively protects the rubber skin from breakage
- Seal ring: rough machining on an ordinary lathe, finishing by CNC lathe — the α angle is processed more smoothly, quality is uniform, and the seal is tight and difficult to leak
- Piston rod and column: medium-frequency hardening of 45 steel, deepening the material 2–3 mm, surface hardness of the piston rod to HRC 55 — an effective solution to seal ring injury; after medium-frequency quenching the workpiece is soft-thrown on the lathe and cylindrical-ground to repair deformation and ensure accuracy
