HYDRAULIC DRAWING WITH VIOLI’S TECHNOLOGIES
Since its founding in 1992, Violi Macchine has become a symbol of Italian excellence in machinery, specializing in various industries, including industrial, goldsmithing, and precious metal recovery. Through its cutting-edge technologies and carefully selected components, Violi has made a mark on both national and international markets. One of its standout products is the hydraulic drawing bench. This article explores the key features and applications of Violi’s drawing technologies.
Founded in 1992, Violi Macchine is a Made in Italy symbol for machineries in several fields, such as industrial, goldsmith and precious metals recovery. Its technologies for tubes, wire and metal profiles working are considered cutting-edge in national and international markets.
Mostly, when we talk about tubes, wire and metal profiles, we are referring to various processes, like drawing, winding, straightening and cutting. Violi Macchine manufactures a wide range of machineries, some of them patented, such as the hydraulic drawing bench. The standard hydraulic drawing bench that Violi manufactures is a machine that reduces the section of bars and tubes by passing the starting product through a calibrated die and pulling it with a hydraulic clamp.
A complete range of machines made with cutting-edge technologies
The traction is in line with the drawing die and the machine maintains a constant drawing speed for the whole working stroke. The operator can vary the machine’s working speed before or during the drawing process This category represents a complete range of machines for drawing round tubes and bars or complex profiles, in all the fields: industrial, pharmaceutical and goldsmith sector to work stainless steel, aluminium, copper and precious metals; it ensures a really high standard in the processed product.
Machines made with cutting-edge technologies, selected components and innovative design solutions covered by patent, are completely controlled by PLC both for the work phases and for safety protection. These machines are designed and manufactured in various versions, based on the sectors belonging and the requests of the costumer. The hydraulic drawing benches, have also been equipped with special components, in addition to drawing, there are requirements in some sectors, starting from coil, also to cut the drawn product to size, cutting it at the head and tail by means of circular saws to programmed dimensions with evacuation of the bar.
Violi Macchine’s automatic tube drawing plant allows the feeding, insertion of the internal tube mandrel, drawing and automatic discharge of the processed tubes, with high productivity requirements. An exclusive system can be installed on request, which allows the drawing to be started gradually in terms of both power and speed.
The logic of the plants, in addition to determining all the processing parameters, has the possibility of inserting recipes and recalling them if necessary; it is also possible to equip the machines with a remote assistance module.
Violi produces also a wide range of straightening machines for wire, bars, round section tubes, square, rectangular and complex profiles. These machineries can be equipped with automatic loading/ unloading and also with cutting-edge fly cutting systems.
