Tube push pointer with automatic tube handling system

S t a n d n o . 6C21-03

THE George AMitchell Company, based in Ohio, USA, has produced more than 60 rotary die head push pointers of various capacities over the last 52 years. A rotary die head push pointer is used when more than three dies are needed to accomplish a specific schedule of point reductions. Mitchell has recently developed and built a150,000lb, four-die rotaryhydraulic push pointer for pointing thin and thick wall aluminum tubes in diameters up to 8", along with an automatic tube handling system, specifically designed for accommodating aluminium tubes, which consists of a tube unbundling unit, entry roll conveyor and easy down discharge buck system. The tubes are subsequently drawn and used for automotive drive shafts and various other applications. The rotation of the newly developed indexing die head is carried out via the use of a servo motor and drive system. The servo system allows infinite rotational adjustment and near-perfect angular accuracy. The original device Mitchell used for rotary die heads was

react swiftly to the needs of the market. Inspiration for new products also comes from within the company. Managing director Ernst Blissenbach encourages his 15 employees to think outside the box and places particular emphasis on a no-blame culture. As a result, there is a constant stream of innovative products. Requirements such as cost savings and emission reductions are gaining increasing relevance in the pipe producing industry and in plant construction. For inside tube scarfing systems, Ernst Blissenbach offers a high level of safety for demanding pipe production processes. BLISSart ® top-quality tools are synonymous with stability, longevity and functionality. head drive system for pointing solid superconductor rod prior to drawing. The drawn superconductor rod will be further processed into wire to be used in MRI machines for the healthcare industry. Other activities Mitchell has been involved in include variable wall drawn tubing, which the company developed back in 1985 and holds a patent on the process. These ‘tailor draw tubes’ can be used for a variety of applications to service the automotive, sporting goods and energy exploration industries.

a rotary cam indexing mechanism. These devices have proven to be very expensive and costly to maintain. In other special applications the servo motor system allows for varying angular positions, whereas the rotary cam indexing devices used previously could only achieve equal angular positions. One major safety advantage of the new servo motor system is that the rotary die head can be rotated by hand during die change over, which facilitates a very fast and safe method for die change. The rotary cam indexing mechanism did not possess this feature. Mitchell also recently delivered a 150,000lb, six-die rotary hydraulic rod push pointer, utilising a smaller servo

Success built upon entrepreneurial vision ERNST Blissenbach GmbH was hon- oured as one of Germany’s most inno- vative SMEs at theGerman SMESummit in Essen last year. The Remscheid- based company joins an exclusive group of prizewinners, and the award for Ernst Blissenbach was the outcome of a two-stage analytical procedure by a team of research scientists. Ernst Blissenbach GmbH’s innovations aim to set standards worldwide. The company develops systems which enable pipes to be produced with particularly smooth internal surfaces, while offering maximum reliability for demanding pipe production processes.
