When RN Gupta & Co Ltd, a family-run company in India with 1,500 employees, required a larger forging machine to produce flanges, pipe fittings, and valves for the oil and gas industry, as well as parts for the automotive and railroad industries, it ordered a new type DG 63h Bêché counterblow hammer from
Schuler.
RN Gupta was founded in 1948 and is one of India’s leading manufacturers of forgings in India, quality is of the utmost importance for them. Explaining why the company decided to order a counterblow hammer from Schuler, president Gaurav — speaking at the factory acceptance test at the Schuler’s Erfurt plant — said: “We were not only impressed with Schuler’s good references and the service available here in India but also by the simulations offered, which helped optimise our forging processes.”
With an impact capacity of over 630kJ, the pneumatic counterblow hammer for RN Gupta can produce flanges and gears with diameters of up to 1,000mm, which is significantly larger than the company had previously been able to offer; and thanks to the pneumatic drive, very high levels of forging energy can be achieved.
Furthermore, the design of the sturdy uprights, together with a solid guide system, ensures high precision during forging. Another advantage of the pneumatic drive is that it has fewer parts compared to a hydraulic drive. This makes the counterblow hammer more robust and simplifies maintenance.
Founded in 1839 at its headquarters in Göppingen, Germany, Schuler has around 5,000 employees at production sites in Europe, China and the Americas, as well as service companies in more than 40 countries. The company is part of the international technology group Andritz.
