1. Yz28 Series Frame-type Hydraulic Press is a kind of multifunctional precision machine which has high speed.

2. Optimized design, the frame is entirely welded with steel plates, and treated to relive stress by tempering for high precision.

3. Cartridge valve equipped for hydraulic control system, reliable, durable and less hydraulic shock, shorter connection pipeline and fewer release points.

4. Centralized button control system, with adjustment, hand and semi-auto operation modes at operator’s choice (set-stroke single and set pressure single).

5. Four-angle and eight-side guide rail in high precision and with strong capacity against deflection, concentrated lubrication.

6. New type of oil cylinder sealing components marked by high reliability and long service life.

7. Sliding blocks operating in high speed, ensuring high efficiency.

8. The slide operating pressure, no-load quick travel and low-speed movement can be adjusted according to technological requirements.

9. Hydraulic cushion is fitted beneath the worktable; adequate knockout hole and hydraulic cushion are prepared on the plate of worktable with the operating modes including drawing, ejection and no ejection.

10. The working speed of this equipment is 3 to 4 times faster than that of Yz41. It employs eight-side guide device and ejecting device, which can automatically eject workpieces with accurate guiding and fast speed.

11. The drawing device can be added to this equipment in order to change moulds easily. But the stretching of large metal parts needs to add hydraulic cushion to this equipment.

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 90s.

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.
