Hydraulic Press Brake Profi 56 CNC

This machine has what it takes: the PROFI 56 CNC universal die-bending press Efficient, economical folding, bending and pressing in the workshop and on the production floor As simple as possible, providing as much as you need, plus various options for individual customization – according to this principle, Boschert GmbH & Co. KG, the specialist for notching, punching, bending and deburring machines in Lörrach, Germany, have expanded the PROFI hydraulic die-bending and folding press series to include the new PROFI 56 CNC model. A press system for universal application was developed based on the oft-proven design on a solid welded frame, with a folding beam guided by four sophisticated linear components as well as two hydraulic pressure cylinders with 28 tons of pressure each. The practical combination consists of four linear guides at right and left for the folding beam, two separately controllable hydraulic cylinders for the raising/lowering operation of the upper tool, two measuring systems per cylinder, two versions of tool holders for different stamping systems, the electrically driven and thus freely positionable rear stop system as well as the control unit.

The result is a compact, high-performance press in yet another performance dimension. The standard PROFI 56 CNC die-bending press is available in the versions PROFI 56/1000 CNC and PROFI 56/2200 CNC with working lengths of 1,000 and 2,200 mm. The clearance between the stands is 890 and 2,100 mm respectively. The stroke is 200 mm and the clearance between the folding beams is 310 mm, so that tall tools can also be used, thanks to the maximum installation height of 325 mm. The worktable is 2 x 270 mm and accepts correspondingly wide tool systems for universal use as a press system for folding, die-bending or press work of all types. The machine has a stable, rigid design for reproducibly accurate individual and series production, and is equipped with sophisticated machine components. Furthermore, each cylinder has its own hydraulic drive and is monitored by its own measuring system. The control unit continuously compares the current positions and adjusts these as required. It was designed as a master-slave control system, so that consistent pressing accuracy is ensured across the entire working width. The control system permits easy entry of the folding length and the bending angle. A maximum of 250 different work programs (folding lengths and bending angles) can be configured and called up at any time. Additional parameters such as tool data, material thicknesses and material data can be entered via „Teach-in“. The entry of the actually required angle is used inprocess during folding/pressing to correct the angle in the mold, and the reproduction accuracy of the press stroke is specified as +/- 0.02 mm. Thus every part is a „good part“. The folding and pressing work can be carried out semi-automatically and therefore with optimal timing thanks to the electrically adjustable and controllable rear stop, which is equipped with two stop bars that can be laterally and vertically adjusted. The working speed is 8 to 10 mm/s and the return speed is 40 mm/s. This facilitates short work cycles.

Available accessories and options include various tool systems, tools and metal support arms with T-groove strips. The user thus receives a cost-effective complete solution ready for operation, which consists of the machine, tools and service in the renowned Boschert quality from a single source.
