TAURUS Blackline

SINCE 1964, ALWAYS A STEP AHEAD!

TAURUS BLACKLINE

The BLACKLINE project has been revised, updated and completed with the entire line of “TR” continuous feeding inclined shear. The range has been expanded with the introduction of TR-VHD (very heavy duty) shears with cutting forces up to 1800 tons, suitable for the continuous shearing of any type of scrap, from profiles, pipes, pantographed sheets to mixed and bulky scrap, demolition, rails, rods etc…

"TR" - INCLINED SHEAR
CONTINUOUS FEEDING

The “AUTOMATIC” INCLINED SHEAR for any type of scrap, regardless its length.

Automatic and perpetual cutting cycle;
Open box with oscillating inclined floor and continuous feeding;
Cutting force from 700 to 1800 tons;
Cutting width up to 1400 mm;
Vertical compression force up to 500 tons;
Lateral compression force up to 500 tons;
Installed power up to 800 kw;
Does not require foundations.

INCLINED SHEAR OPERATION

The scrap, if not in particular cases (bundles of pipes, rails, scrap from the production of profiles, bales of scrap, shipwrecked scrap...), is of undefined dimensions that must be reduced in order to pass through the mouth of the shear.
For this reason the shear is equipped at the entrance with a vertical "hammer" clamp and two side flaps. Combining the action of these elements it is possible to have a size reduction of the scrap.
The gravity "pull" , aided by the movement of the oscillating floor, the scrap into the inclined feed box under the blades of the shear.
A positive reference, placed at the exit of the shear and adjustable from console, stops the scrap at a predefined length. After that the scrap is ready to be shared. The three-stage vertical "hammer" clamp placed at the inlet of the shear adjacent to the blades (3), moves vertically compressing the material from top to bottom.
The function of the three compression stages is to compress the scrap vertically in successive stages.

The two side flaps (2) for lateral prestressing are hinged on the outside, frontally to the guillotine structure. The combined action of the flaps (2) and the vertical clamp(3) permits the reduction of the scrap size allowing the material to pass through the shear mouth.

The scrap to be sheared is loaded into the feeding box, fixed in front of the shear structure, composed of a hopper closed at the sides, with the upper part open and the bottom inclined and oscillating floor (1).

The operator's work is therefore limited to loading the feeding box.

The "TR" shears have a limited footprint, concentrate their weight on the elements subject to stress and wear, can be loaded from both sides and are controlled by a single operator.

INCLINED SHEAR OPERATION

ADVANTAGES AND DISADVANTAGES

The reasons that lead some operators to prefer the system with open box continuous feeding over the classic and traditional systems that foresee a compression phase before the automatic shearing cycle, can be summarized as follows:

unbeatable machines in the shearing of long and/or in bales
possibility to shear materials with lengths longer than the size of the feeding box,
lower ordinary maintenance costs due to less wear and tear,
the convenience of a single operator in charge at the same time to load and to control the operation of the shear,
less space occupied, due to the compactness of the shear and its limited dimensions,
less production downtime for the preparation of the scrap to be sheared,

On the other hand, this type of inclined shears continuous feeding presents difficulties and limitations such as:

The cutting length, whose maximum size is defined by the external positive stop but is not certain and constant, because it is left to gravity and friction resistance,
The cut rejection due to excess of scrap under the guillotine, since there is no longitudinal pusher, causes the machine stop temporarily with manual intervention to free the blades from the material that has produced the overload,
The loading height makes it difficult to see the inside of the feed box,
The difficulty of maintenance interventions due to the inclined parts of the structure that forces to not easy operations,
The inability to produce scrap bales.

Compared to traditional shears with oscillating lids, the inclined shears are continuous feeding and do not have the downtime due to the scrap compression phase, to the return of the feeding cylinder and to the opening of the lids at the end of the cycle. It is true that the traditional systems, for each cutting cycle, haven't the closure of the flap, the movement of the inclined floor, the over stroke of the vertical pusher with three reduction stages.

The choice between the two working systems is therefore left to the needs of the user who has to examine the limits and merits of the two different systems in relation to his needs, types of scrap, available space, size of the investment…
