Bendcheck assures straightness ABSOLUTE straightness is one of the concise quality criteria in the production of round bars and pipes. Bendcheck – the precision laser measuring system from Zumbach – monitors bending continuously without missing any sections directly within the production process. saves considerable time through the use of the online data check. Bendcheck can be used for synchronous real time scanning in the production process; quality assurance directly after the straightening process; direct integration in the production process (customer-specific installation); and no time consuming and laborious checks with manual tools.

Bendcheck calculates the deviation of the central measuring head in respect of a virtual straight line projected from the position of the left head to the position of the right head, from the data. This value is either divided by the distance or by the distance squared. The operator can select the preferred formula for the bend calculation. Thanks to this information, the bend of the product is continuously calculated and graphically displayed. Bendcheck can be operated in a continuous measuring mode without encoder, or in a triggered mode where the measurement pulse is generated by an encoder along the cutting edge. The respective data is clearly shown on a display board. Diameter, absolute bend value, bending angle as well as the individual and current measurements of the three measuring heads are clearly shown. Additional statistics complement the informative value of the measurement. Zumbach Electronic AG – Switzerland Email: sales@zumbach.ch Website: www.zumbach.com

This replaces the ODAC ® laser measuring heads used currently to manually spot test with a non-contact online test for bending. Apart from the gain in quality the manufacturer also

The system measures the position and diameter of the product at three different locations along its axis.

Tool change speeded up THE tube bending machine manufacturer Schwarze-Robitec developed the new rapid clamping system Quick Tool Unlock for tube bending machines according to the engineering motto “keep it simple”. This allows quick change of the bending formers without tools and therefore reduces set-up time noticeably.

The rapid clamping system is comprised of a split tension rod with clamping lever as well as a swivel device. While in customary models the continuous tension rod to the swivel cross arm needs to be unscrewed at the top of the bending former for a tool change, the procedure is much simpler with the Quick Tool Unlock. Here, only the clamping lever is actuated and therefore the connection to the swivel cross arm disengaged. The swivel device can subsequently be opened so that the bending former is exposed at the top. In interaction with the automatic tool clamping, the bending former can be removed without any difficulty. There is no longer any need for the previously necessary unscrewing of the bending former. The work-saving technology is absolutely self-explanatory and quick. Another plus for Quick Tool Unlock is that all connections from static to rotating parts are carried out via rolling bearings, which contribute to the durability of the machine.
