Hydraulic Unit

Variation of Easy Powers: Laborsaving by a high lock unit!

• A high lock unit is most fitted for the system which performs a hydraulic lock. 
• This is maintenance-free, and complicated management like an electric pump is unnecessary
• An air-driven pump is adopted and, moreover, this is explosion-proof and energy-saving
• This unit is designed compact and low-cost. 
• Flawless safety confirmation is provided and abnormalities are quickly caught with the switch for pressure detection

HU High Lock Unit is a hydraulic unit that is a combination of the SR pump (air-driven hydraulic pump), the air pilot type hydraulic switch valve (non-leak type), directional control valve, pressure switch and also an optional circuit, and a spare circuit mounted on the manifold. So this unit has a flexible design but compact, so useful for any application.

HMS Power Units are compact hydraulic units that generate high-pressure oil by the use of SR pump (pneumatic-driven hydraulic pump).

• Incorporated with the non-leak type VF valve units, HMS POER UNITS serve best as a hydraulic source for the clamp system or die-lifter.
• SR pump provides a wide selection to meet various working conditions and applications.

VF Valve Unit are pilot-air-controlled non-leak valve units that employ manual-driven valves (M-301).

• Being a manual-operated valve, VF-MVALVE UNITS can simplify the system and provide easy operation.

Air-driven Hydraulic Pump

SR Pump / SR040/063/100 are air-over-hydraulic pumps operated with compressed air. The pump’s discharge pressure Is controlled by operating alr pressure. Oil flow rate increases at the low hydraulic pressure and decreases at the high hydraulic pressure. When air pressure is balanced with hydraulic pressure. the pump stops automatically and will start automatically when hydraulic pressure decreases. The pump, then, operates continuously until air pressure reaches equilibrium with hydraulic pressure.

Accessories

• Various needs can be satisfied by combining them. 
• A valve sheet part is of the non-leak structure by surface adjustment.

APCO, APCC Hydraulic Switching Valve is a 2-position-3-port change valve that changes an oil flow channel with an air pilot signal.

OCV Hydraulic Switching Valve: A 3-position-4-port rotary valve that changes the direction of hydraulic pressure by operating a handle knob.

EF,ET Pressure Switch: Various pressure switches covering low pressure to high pressure.

RLM, RL Relief Valve is a relief valve in small size and with sufficient rigidity which can be used for general hydraulic pressure in case of a relatively small flow.

AHPC Pilot Check Valve is a hydraulic change valve that controls high hydraulic pressure by air pilot pressure and mounts an accumulator supplying oil when the pressure becomes low.

APC Pilot Check Valve is a hydraulic change valve that can control high hydraulic pressure by low air pilot pressure.

Hydraulic Die Clamp

LZ Lever Clamp is a hydraulic clamp which tightens through a lever by the power of a single spring return type cylinder. (Maximum Allowable Working Pressure: 24.5MPa)

SZ,SY Straight Clamp is a hydraulic clamp that tightens between a U slot and a T slot by the direct power of a single spring return type cylinder.

LY Lever Clamp is a hydraulic clamp that tightens through a lever by the power of a single spring return type cylinder. (Maximum Allowable Working Pressure: 18.1MPa)

SFZ Center Hole Cylinder can be used by pushing or pulling through the power of a single spring return type single cylinder (single spring return type cylinder).

This is light in weight and compact in size, and, moreover, robust. 

The kind of piping port can be selected as an option.

Travelling Clamp

USZ Self Travelling Clamp: Self Travelling Clamp for Large-sized Transfer Press and Dedicated to Upper Die

MSY Self Travelling Clamp: The clamp moves up to 300mm in maximum, detects an upper die automatically, and is a self travelling hydraulic clamp dedicated to an upper die for clamping.(Maximum Allowable Working Pressure: 18.1MPa)

MSZ Self Travelling Clamp: The clamp moves up to 300mm in maximum, detects an upper die automatically, and is a self traveling hydraulic clamp dedicated to an upper die for clamping.(Maximum Allowable Working Pressure: 24.5MPa)

SSZ Non-touch Clamp is a hydraulic clamp of the short slide system which moves a single spring return type clamper SZ series by an air cylinder.(Maximum Allowable Working Pressure: 24.5MPa)

SSY Non-touch Clamp is a short slide type hydraulic clamp that moves a single spring return type clamper SZ series by an air cylinder. (Maximum Allowable Working Pressure: 18.1MPa）

SLY Non-touch Clamp is a short slide-type hydraulic clamp that moves an LY-type clamp by an air cylinder.

LYS Non-touch Clamp is an integral-type short slide hydraulic clamp that has built the air cylinder and the micro-switch into LY type of hydraulic clamper.

Swing Clamp

NSY Swing Clamp: Hydraulic clamp most fitted for press line and medium-sized press

A special cam operates in the middle of the stroke of a hydraulic cylinder, and this makes a clamp rod swing. The hydraulic cylinder introduces the structure which restricts the cylinder output in order to reduce the time for unclamped stroke and protect the swing cam.

AS Swing Clamp: An air cylinder acts on an eccentric cam axis, and a strong clamping force is achieved by the amplification mechanism of a cam. Moreover, the type with a built-in spring holds the clamped condition by spring power, even if air pressure is lowered.

HSK Swing Clamp: A clamp rod swings 90 degrees by air pressure, and this makes it suitable for lower die clamp application.

Rotary Clamp

RPY Rotary Clamp: A clamp rod turns 90 degrees, expands, and contracts by air pressure, and this is a hydraulic clamp that tightens die by hydraulic pressure.

RAY Rotary Clamp performs tightening of a die by hydraulic pressure and is a hydraulic clamp whose clamp rod turns 90 degrees from the position of tightening a die by air pressure.
