It is alarming how much discharged air welding fixtures are permanently exposed to. Certainly, the air is sound absorbed, cleaned, hardly raises dust and is ideally oil-free.

When weight is of decisive importance in the installations, each kilogram that can be saved is of value.

Almost 2 kg can be saved with the special LW series of our Vario clamps which are immediately available in the sizes 40, 50 and 63.

The predominant function of the toggle-joint clamp is to move the contour block in the desired working position. In general, the contour block is mounted with the aid of a hole pattern with two stud boreholes and two through holes. Less conformity can be found as to the clamp arm height, although the requirements on clamping fixture are the same everywhere.

Although the bending of tabs is a rather exotic procedure in body framing, this forming technique also requires an industrial-suited tool system.

What is already well know from EXPERT-TÜNKERS now comes new from TÜNKERS-the rotating indexing units. However the TÜNKERS units are smaller and operated with pneumatic drives.

Our EXPERT rotary table EDM is conceived for purely manual operation. Simply worded, this product comprises of a base frame with robust bearing and a table plate.

The flange clamp was developed for special body framework applications and as a customised solution for our regional customers. This clamp is a modified version of the well-known Alpha clamps, APH 50, APH 40 and the miniature clamp K 25.

The ongoing discussion about the climate killer CO2 has increased the sensitivity to the topic energy consumption in production. With more than 1,000 operating cycles per day, pneumatic clamps virtually run marathons in the production lines. Anybody who moves a lot burns a lot of energy; hence, the pneumatic clamps account for a considerable degree of energy consumption in car body manufacturing with more than 1,000 to 2,000 units per production line.

The high pressure networks of 12 bar in the plants are used to generate high forces with standard pneumatic cylinders s. a. in welding application. Especially with a view to energy efficiency, high pressure networks are met with criticism, as the costs of the preparation of compressed air rise exponentially with the pressure.

Even though very rarely used in practice, locating pins are responsible for one of the most important tasks in automated body framework: the protection of the operator.
