Ursviken GSA Guillotine shears

Ursviken GSA Guillotine shears 

Ursviken has become a familiar name within the plate working industry. Thanks to our knowledge and ability to constantly meet customers' demands, we have reached a market-leading position within the manufacture of plate working machines worldwide. Our standard program includes CNC-controlled hydraulic shears for cutting plates of thicknesses up to 45 mm. The machines are built with well-proven and reliable components, chosen to ensure the best possible cutting results and economical production.

Automatic setting of blade clearance The control system is especially developed for the Ursviken shears. In addition to an advanced control program, it contains a unique function that interprets important machine information into written text. This increases the capacity of the shear, with correct adjustments always giving a better cutting result. Furthermore, the shear blades will last longer than in shears with fixed cutting angle or in swing beam shears. The control system can be equipped with Remote Service Support (RSS), which makes it possible for Ursviken technicians to carry out troubleshooting and updating of machine functions over a telephone modem.

Many of our machine deliveries include CNC-controlled equipment for feeding in and out, conveying, and stacking. Ursviken has vast experience in the design and manufacture of CNC-controlled cutting plants, where, for example, cutting, material flow, and intermediate stacking are optimized in respect of economy and productivity.

Steplessly variable cutting angle The cutting angle is steplessly variable. The setting is done automatically or directly from the control panel, and the angle set is displayed in writing on the panel. Thin plates can be cut with a small angle, which reduces the determination, gives better cutting results, and shorter cutting time. In order to further improve the cutting economy, the standard has the possibility of automatic limitation of the cutting length.

Unlimited turnable shear blades The shear blades can be turned and are the same in bed and beam. The blades have a rectangular cross-section and thereby four cutting edges. A special attachment and design make it simple to change and turn the shear blades.

Plate holders increasing the power when needed A large number of closely located, individually acting plate holders hold the plate during the cutting cycle. During the actual cut, the plate holder power is automatically controlled by the cutting power. The plate thickness is also automatically considered so that the power is adjusted when cutting thick plate and different material qualities.

Shadow light increases precision Ursviken shears are equipped with a shadow light for cutting to a scribed line. The upper shear blade gives a distinct borderline between shadow and light and marks out where the cut will be. The shadow light follows the setting of the blade clearance, thereby always securing an exact cut.

Rigid motorized back gauge The back gauge has servo operation and ball screws. Desired setting and cutting cycle are programmed into the control system with an interval of mm. In order to allow the best possible accuracy, stopping is always in minus direction towards the operator. The cutting movement of the shear is blocked until the back gauge stops at the programmed measure. The feed-in is therefore quick and effective, without the risk of miscutting. The gauge reverses automatically during the cutting movement.

A feed-out conveyor that increases productivity By adding a feed-out conveyor to the shear, the handling time for stacking of cut plates and removal of trim cuts can be considerably shortened. Ursviken has feed-out conveyors of different executions and with different functions depending on the type of production and demand for productivity. There are, for example, conveyors with pneumatically controlled plate holders, scrap separation, and adjustable stacking function.

Feed-out conveyors are optional equipment.

Unique finger guard with self-detecting safety setting The GSA shears have an electrical and hinged finger guard. The guard can easily be completely turned up for checking the position of the plate when cutting to a scribed line, at which time it is not possible to operate the shear. The finger guard is so designed that from a safety point of view, the correct distance between the height of the opening and the distance to the plate holders is automatically set. The GSB is equipped as standard with a light curtain. It is also available on the GSA shears.

With QBC, the shear blades can be exchanged at least 20 times faster Sharp shear blades always give a better cutting result. By using the Ursviken QBC (Quick Blade Change) for shear blades, the time for changing or turning shear blades can be considerably reduced. In a three-meter shear, one man can change or turn the shear blades in 15 minutes. Thanks to the extremely short handling time, you can always choose the right shear blade for every plate quality.

QBC is optional equipment.

Ursviken Guillotine shear GSA - reliable production machine for plate thicknesses 8 to 25 mm and cutting lengths 3 to m

The Ursviken GSA is one of the most well-known hydraulic shears in the world. The GSA shears are the base of the heavy program, made for cutting heavy plate with relatively small cutting angles adjustable between 1 to 4. But the shears also function perfectly for cutting thin plate.

GSA is equipped as standard with openings in the frame to make it possible to cut plates longer than the nominal length of the machine. The hydraulic system is built up by modern block hydraulics with logic elements, ensuring even and shock-free operation.

The GSA shear is available in 16 models.
