Knuckle-joint presses for high-speed blanking deliver top-quality industrial disks

As varied as the application areas for industrial disks may be, the requirements of the companies using them are certainly unmistakable. When it comes to parts with a high functional and safety relevance, the utmost quality is required. Zero defect tolerance is the key expression. In addition to the supplier’s development and manufacturing expertise, it is the performance and reliability of the machines used which contribute most to economic efficiency. Schuler therefore offers an extensive range of knuckle-joint presses which are specially tailored to the process chain involved in the manufacturing of industrial disks.

Quality is the key criteria for the economic production of high-quality, mass manufactured blanks, such as industrial disks, chain link plates and retaining or sealing washers. Those companies which can offer the entire process chain – from blanking, to coining to multi-stage forming operations – enjoy sustainable competitive advantages. Schuler presents a range of presses tailored exactly to such requirements.

Press systems for all stages of high-speed blanking

The BMK range of high-speed stamping presses with knuckle-joint drives are designed to deliver maximum output and high part quality. These extremely precise press systems can produce high-volume blanked parts in compound dies at up to 250 strokes per minute, enabling the production of as many as 12,500 parts per minute. At the same time, the knuckle-joint drive reduces the impact speed of the slide and thus enhances edge quality and prolongs die service life. The dynamic mass-counterbalance of the slide also ensures that the machines run quietly – despite the tremendous speeds. As the compound die enables simultaneous blanking of both inner and outer contours, parts can be manufactured with minimal center deviation and excellent surface flatness and parallelism. The presses are available with forces of 2,000 or 4,000 kN. They are particularly well suited to the manufacturing of parts which are either mounted directly after subsequent deburring or form the basis for further forming operations.

Coining and sizing presses: quality and speed

A typical subsequent operation for industrial disks is coining or sizing, in order to manufacture functional parts such as high-precision industrial disks or washers for motors and gearboxes. Schuler offers extremely fast-running systems for such purposes with its EMK range of knuckle-joint presses. With forces of 1,000 to 3,000 kN and speeds of up to 750 strokes per minute, these presses are particularly well suited to the manufacturing of parts requiring extremely high accuracy. Thanks to the machine’s high rigidity and established drive technology, the manufactured products meet extremely tight tolerances. And because the machines are equipped with a mechanical quick-changeover device, users also benefit from short setup and changeover times. In view of the extreme cost pressure and tight margins faced by manufacturers, such benefits can have a decisive impact on the economic production of high-volume parts.

Automatic blanking and forming presses for the production of complex parts

Finally, the universal blanking and forming presses of the TMK range are ideally suited to the manufacturing of complex stamped parts. With press forces of 2,000 to 3,150 kN, the lines are geared toward the production of industrial disks and can be individually adjusted to a variety of forming tasks. As the presses use standard components which have proved their worth in daily use for over three decades, high quality and process reliability are guaranteed. Further safety is provided by the central lubrication unit, which is fed by a progressive distributor. As an option, the lines can be operated with progressive compound dies or a transfer system and are thus ideally suited to the production of ready-to-install precision parts.
