A series of EYP model pulse wrench presents highest efficiency with simple mechanism of pulse. Oil is filled everywhere inside of the Cage which is combined with built-in Shank-anvil. Shank-anvil has two Pistons that are located 180? opposite. Each Piston is fitted on with a Roller which is always contacting inside wall of the Cage. There are two mounted portions that are protruded from inside wall of the Cage. Those two mounts are located 180? opposite, also. Shank-anvil is not directly connected with the airmotor, but the Cage is dirctly connected with it.When Shank-anvil is under no load ie., free running, it is rotating together with the Cage. Once Shank-anvil is on load, it begins to stop rotating but the Cage keeps rotating. Then, two mounted portions in the Cage begin to push a pair of Rollers together with the Pistons towards the center of the Cage and then, this movement of pistons forms a pair of sealed chambers in the Shank-anvil where oil flow will be intercepted. After oil flow is intercepted, oil in the chambers where a pair of Pistons are moving will be compressed and will generate pulse in a moment to transfer energy from the Cage to the Shank-anvil.

PULSE MECHANISM

New EYP model pulse unit recently developed has a pair of pistons. Oil is filled in the cage and shall be efficiently compressed in the sealed chambers in the shank-anvil. A pair of pistons and a pair of balls-steel will form a pair of sealed chambers in the shank-anvil. (Patented)This simple mechanism helps to lower the number of parts required, and makes it easy to perform repair work. EYP model pulse unit simply generates single pulse per single rotation without using any mechanical cams. Shank-anvil has a pair of pistons, and each piston is located 180? opposite. There are two mounted portions in the cage that are protruded from inside wall of the cage. These protruded mounts in the cage are corresponding with a pair of pistons. (Patented)

DIRECT AIR SHUTOFFShut off mechanism to intercept supply-air is directly related to main valve. After reaching pre-set torque, supply-air shall be automatically shut off. (Patent Pending)Shut off mechanism provides most reliable and stable performance in terms of torque accuracy even if the suppy-air pressure should be 0.4MPa.

MOST DURABLE OIL SEALOil seals are to intercept lower pressure oil. This mechanism helps to extend life of seals much longer than the case as oil seals are to intercept higher pressure oil. Relief valve to adjust range of torque is positioned in the center bore of shank-anvil, which provides easiest handling for torque adjustment.

RELEEF VALVEShank-anvil has two-pieces structure consisting of the cap-anvil which forms square end and the body which forms substance to generate pulse. (Patent Pending)

CHANGEABLE SQUARE ENDThis structure is adopted on the EYP-80AS, EYP-300AS and EYP-380AS models. In case of the EYP-80AS, for example, the square end can be selected among 3/8 inch, 1/2 inch and the one to accept bit-driver. Changing cap-anvils can be easily executed on the job site without using any special tools.

ERGONOMIC GRIP HANDLEErgonomic requirements like less vibration or less reaction force are realized on the EYP model pulse wrenches. To enhance these features, the grip-handle is covered with the same rubber that is used on the tennis racket. This rubber grip is supplied as a standard equipment to help to reduce burden on wrist, arm and shoulder of the operator.

SLIPPING TOOLS DESIGNED FOR SERVICE AND REPAIR:

• TSC Calibrated Wrenches incorporate Torqueleaders unique slipping technology, eliminating the possibility of overtightening
• The wrenches are non length dependent, giving accurate repeatability regardless of where the tool is held
• The micrometer style scale allows precise adjustment resulting in better accuracy. The built in adjustment lock prevents accidental adjustment
• Designed to operate in any environment from the toughest Production line to the most delicate Electronic Assembly area
• EPA compliant for use in electrostatically sensitive applications
• Designed and manufactured to exceed the requirements of ISO 6789:2003
• Accuracy +/- 6% of setting
• ISO 6789:2003 classification 2A
• Accessories available (end fittings, adaptors & sockets)

Entorquer present wrenches are designed and made for the assembly plant, where they need to perform repetitive torque application to a present value.

• */-4% accuracy
• Classified to ISO 6789:2003
• Present adjustable with special tool
• 52 tooth ratchet
• Industrial grade construction
• Molded grip for operator comfort
• Light weight

FOR GREATER CONTROL OVER THE PRODUCTION PROCESS:

• Signal Transmission Options
• The Torqueleader range of TBN, TSN, TSP and STB Production tools can be supplied with a choice of two options for transmitting a signal when a tightening event has taken place. Each time the operator uses the tool a signal is sent or can be recorded, offering greater control over the production process
• Switch and Cable Tools use a mechanical switch which is operated each time the wrench achieves its set torque. The switch is connected via cable to the Production Line Control System. This option is a cost effective system for Production environments as well as offering guaranteed torque control

DESIGNED TO PROVIDE FAIL SAFE TIGHTENING:

• The TBN, STB and TSN Switch Tools send a signal to a remote monitoring device when the preset torque has been applied, providing greater control over the production process
• The TBN, STB and TSN Switch tools are based on the well established Torqueleader technology and bring all the benefits of reducing the risk of overtightening
• Switch tools can be integrated into most Production Line Control Systems, as well as operate counters and gate switches
• Torqueleader Switch tools come complete with a 6m cable featuring a cable strain relief system
• A Signal Delay Unit (SDU) is available as an optional interface between the Switch tool and Production Line Control Systems. Its function is to prolong the signal duration to guarantee communication
