Underbody Clamp operation Instruction

1. Description

The underbody clamp is a high-power tool designed for usein clamping tasks processing sheet metal. lt consists of apneumatic cylinder,a metal housing with mounting faces.front and rear, and a locating pin with an integrated clamphook.
When used in clamping, the pneumatic cylinder moves anintegrated toggle lever joint to accentuate power; the jointtriggers the swivel action of the clamp hook. The positioncontrol of the clamp arm is achieved optionally through anintegrated inductive sensing cartridge

2. Safety

The underbody clamp was not conceived to be a completetool,ready for independent applications and has thereforenot been fitted with safety equipment. Only when it is correct-lyinstalled in a production system and a corresponding safe-ty control system is added, will all safety requirements bemet.
Should any faults occur that place personnel at risk, theunderbody clamp is to be switched off immediately. Mainte-nance measures are only to be undertaken when the ma-chine is at a complete standstill and by suitably qualifiedspecialists.
After maintenance work has been carried out, the protectiondevices are to be refitted in the correct way.

3. Assembly of the underbody clamp

The clamp is installed by means of four socket headcap screws on the mounting face, front or rear.
Connect to supply air between pneumatic controlvalve and clamp (connections "N").Attention: For fine adjustment of speed of clampingprocess, the use of external directional flow contro!valves is recommended.
lf external magnet switches are used, they are to beassembled and connected.

A.Inductive limit switch set (T12)

Set plug on socket "C" according to the electrical designof the pneumatic clamp(see circuit diagrams), and tight-en.
Caution: Operation with incorrect or too high voltage canlead to short circuiting and danger to personnel.

B.Pneumatic limit switch set (T08/T10)
Connect control line for pneumatic limit switch set to therear of the clamp according to the marking (P, R).
Attention: Working pressure for control lines max. 6bar.

4. Set up for the Underbody Clamp

Caution! Danger of crushing!
When the clamp hook is being set, fingers could be sev-ered or crushed. Do not reach into the toggle lever area ofthe clamping hook while the underbody camp is in opera-tion. Before adjustments are started, the air supply must beshut off
For sight checks of the support roller, remove cover "B"by releasing the screws.
Move the underbody clamp to the opened position, theclamping hook is inside the locating pin; support rollersare in lower position.
Set work piece on locating pin and move to desiredposition.
Move underbody clamp to clamping position; the clamping hook lies on the work piece; the support roller is inthe upper position.
Attention: The support roller must be at the upper limitstop. Only in this way the operation of the upper dead-centre lock can be ensured.

5. Replacement of limit switch cartridge

Remove limit switch cartridge by releasing screw "D"Assemble new limit switch cartridge.

6. Maintenance

The underbody clamp is designed for high production ap.plications; it is equipped with high quality, low-maintenancebearings,seals and quides. This technical concept allows 3million cycles without significant component wear.Because of the closed structure no special maintenance ofthe underbody clamp is necessary.
Caution: Damage can be caused to the underbody clampby cleaning with steam-jet or dry ice.
