In these days in north Italy has been installed and tested a new shear baler TAURUS BLULINE ACH873. The shear has the following features: cutting force tons 800 with n.2 shear cylinders; slides in HARDOX mm 40, a clamp cylinder of tons 140. Which are the characteristics of an 800 tons shear head? The shear head is operated hydraulically by 2 cylinders. The benefits of the twin cylinder configuration are:
– to minimize the sliding friction between the blade holder and guides which reduces wear and tare.
– to better balance the movable blade during the shearing operation.
– 2 smaller cylinders are easier to service than one large one.
Eccentric pins are used to adjust the clearance between the slides and blades, to maintain the right position during time.
Interchangeable bolted on guides can easily be replaced when worn to avoid expensive reconditioning shear head walls
Wear plates made of 40 mm thick Hardox steel to protect the parts subject to wear
Mobile blade holder guides made from hardened steel and a synthetic polymer which embeds foreign bodies in the polymer to avoid damage to the guides.
The front surface of the mobile blade holder is also pro-tected with a Hardox wear plate.
Fixed blade with replaceable blade seat to preserve tight clearances between the fixed and movable blades, even after many years of operation.
These are just some of the major compositional characteristics of the TAURUS heads. All shears are machined internally, through high-precision numerical control machines, to ensure the strength and sturdiness that TAURUS has demonstrated for over 50 years.
