The Voortman V505-160T angle punching and shearing machine is specifically designed with the challenges and needs of the tower fabrication industry in mind. As a result of the machine’s high level of automation and unmatched processing speed, manufacturers of steel towers can be assured of a significant improvement in productivity. The Voortman V505-160T is developed to optimize material efficiency by allowing production with only minimal scrap, while its robust construction assures high quality results.
CROSS-TRANSPORTS WITH INTEGRATED MAGNETS The Voortman V505-160T punching and shearing machine owes its improved productivity to a number of features that enable high speed processing. Starting at the infeed side, the Voortman V505-160T is standard equipped with cross-transports with integrated magnets that separate the angle profiles from each other. With the sturdy tiltable roller conveyor, the angles are loaded very easily and fully automatic into the machine. The need to manually load the transports is therewith eliminated. FAST SERVO DRIVEN GRIPPER TRUCK Productivity is further improved by equipping the Voortman V505-160T with the fastest gripper truck on the market. The gripper truck is servo driven and runs at a maximum speed of 110 m/min. The gripper truck comes with a very accurate material sensor allowing full speed approach of the angle profile. The combination with the cross-transports with integrated magnets makes the complete infeed fully automatized, therewith eliminating the risk of undesirable variances caused by human errors at the start of the process. Both the infeed and outfeed are available in 6, 9, 12 or 15 meter configuration. POWERFUL PUNCHING CYLINDER The Voortman V505-160T has two rigid punching frames, each holding three rigid punching tools. On each punching frame a powerful 80 tons hydraulic cylinder is mounted which in turn punches angles up to a maximum thickness of 19 mm. The punching cylinder is mounted on two linear guidance rails and is driven with two pneumatic cylinders. This design enables a fast tool selection by which running speed is enhanced and productivity improved.
HIGH QUALITY RESULTS
ACCURATE PROFILE POSITIONING The high speed processing of the Voortman V505-160T punching and shearing machine comes without any compromise to the quality of the end product. On the contrary, the Voortman V505-160T is equipped with a number of clever features that assure high quality results under the most demanding conditions. To guarantee that the angle profiles are always perfectly positioned before the punch reaches the material, the machine comes standard with three solid external down keepers. Additionally, Voortman equipped the two punching frames with their own down keepers to make sure that the material is always kept in place when the punching tool retracts. This reduces punch wear, offering a high quality of the end product. PRECISE PUNCHING FRAMES High quality of the end product largely comes down to the design of the punching process. In order to prevent vibrations in the machine while punching, the two punching fames of the Voortman V505-160T are mounted on a sliding frame with a hinge and a spring load. The positioning of the punching frames on two linear guidance rails is done with a servo drive and a spindle. This design assures a very accurate punching process which is not compromised at high running speeds. OPTIMIZED SHEARING The shear of the Voortman V505-160T features a heavy 245 tons cylinder for cutting the angle profiles. The shearing blade itself is optimized on all four corners. It can cut every angle in the range from 35 mm to 160 mm with the right radius, resulting in cutting quality as specified. EFFECTIVE BARREL MARKING The Voortman V505-160T can be equipped with a barrel marking unit which has space for eight cassettes, each containing a high number of thirteen characters. With the barrel marking unit, a complete row of characters can be imprinted at once. The height of the characters can be chosen in either 13 mm or 16 mm, in both cases 10 mm wide. The characters are pressed with a force of maximum 130 tons. This gives clearly visible and identifiable results with depths between 1 mm and 2 mm. Alternatively, a hydraulic disk marking unit is available. The disc holds 36 characters, which are selected automatically.
SMART TILTING DEVICE AT OUTFEED SIDE Voortman paid a lot of attention to optimizing the user friendliness of the V505-160T angle punching and shearing machine. The outfeed side of the machine comes with a special tilting device which lifts for short products and feeds the long products onto the outfeed roller conveyor. The outfeed roller conveyor can tilt to both sides for unloading. Underneath the shear at the outfeed side there is space for a removable waste bin on wheels which is delivered standard with the machine. LIGHTWEIGHT PUNCHING BLOCKS Removing and replacing punching blocks can be a complex and time consuming activity. To optimize ease of use, the Voortman V505-160T is designed as such that each punching block only weighs 7 kg each, enabling easy tool changing for the machine operator. Furthermore, the easily accessible die is separated from the punch and fixed in the punching frame itself. VACAM OPERATING SOFTWARE Just like all other machines from Voortman, the Voortman V505-160T is operated and controlled by its proprietary and very user friendly VACAM software. All Voortman machines have the same “look-and-feel” which significantly reduces the learning curve for the operator. The VACAM operating software is a Voortman development and is completely developed in house. It is the result of decades of experience in steel machinery and is continuously optimized by adding new technologies. Because VACAM is an open platform, an API can be used to easily exchange production data between VACAM and ERP or MRP packages. It allows the user to monitor production real-time.
SHORT MATERIAL REST LENGTH To minimize waste and therewith achieve a high material efficiency, the Voortman V505-160T offers the possibility of a minimum material rest length of only 65 mm. This short rest length, which is realized by applying an end cut, is measured as the length between the gripper truck and the shearing blade. PRODUCTION WITHOUT SCRAP Alternatively to the end cut, the operator can opt for a no end cut principle. In that case, the gripper truck places the angle at the right position, retracts (so that the machine can punch as close to the profile end as possible), grips the profile again and feeds it out of the machine. Applying the no end cut principle is especially useful for tower fabricators that source angle profiles which are already cut to length.
