Kammarton Bulgaria delivered and installed a profile bending machine COMAC model 305 HVP2 for the wagon-building and wagon-repair company "Traktsia", v. Samuil, region Razgrad.
Italian COMAC bending machines are designed and manufactured with over 35-years experience, with the goal of providing top level performance, with high accuracy and repeatability, constant throughout the useful life of the machines and almost maintenance free. Hence the structural oversizing of the parts subject to stress, the thorough precision of machining and the usage of high quality OEM components, whose parts are readily available worldwide. The machines comply with standard 2006/42/CE.
Main features of COMAC profile bending machine model 305 HVP2:
- Three driving rolls to guarantee maximum drive on the profile.
- Bending rolls independently adjustable, for double pre-bending capability on the leading and trailing end of symmetrical profiles.
- Diameter of the upper shaft - 80 mm
- Diameter of lower shafts - 70 mm
- Diameter of rolls - 245 mm
- Rolling speed – 6,1 m/min
- Lateral guide rolls with three-dimensional adjustment.
- Modular rolls that allow the bending of most profiles.
- Standard bending rolls of alloy steel, heat treated to surface hardness 60 HRC.
- Control panel P2 - Free standing remote control station to control the machine in safety.
- Possibility to install the machine both in vertical and horizontal position.
- One-piece fabricated steel frame.
- Torque limiter installed on top roll shaft.
- Shaft and pinions installed on high dynamic load roller bearings.
- Gears coupled directly on splined shaft
The machines are controlled by means of a push button board that allows the variation of the position of the bending rolls and by a pedal that control the advance and retreat of the profile. Depending on the deformation work to be performed, numerous additional controls are available like, for example, the hydraulic regulation of the lateral guide rolls, the speed regulation by means of a potentiometer, the double speed positioning of the bending rolls and the remote control of the special tooling. In case a high repeatability is required or if particular bending geometries must be achieved, the machines are equipped with programmable positioner (NC), numerical controls with independent axes and numerical controls with interpolated axes (CNC).
