Fully Automatic Production Facility for Ornamental and Facing Rings

Task: 

Producing rings off the conveyor belt – is that your problem?
The manufacture of ornamental and facing rings from various materials for a wide variety of applications:
case rings for timepieces, ornamental and facing rings for pressure gauges and other instruments, protective rims for cooking pots, ball bearing cages, cooker hotplate rings etc. This has certainly caused many a headache, because the producion of the rings must keep in step with that of the products they`re used for.

Solution:

We`ve dealt with the problem once and for all – with our automatic ornamental ring machine.
The machine makes all formable materials into ornamental rings, facing rings and case rings for a wide variety of applications.
Between the minimum and the minimum and the maximum diameter (see specifications) all ring sizes can be produced with various profiles.

Resetting is achieved simply by changing the mountings.
Setting time is just 2 hours. The entire process is fully automatic.
The machine is selfmonitoring in the event of a fault.
So one person can operate several machines – or he can operate one machine and at the same time produce small runs of intermediate size in manual operation
(and here too we have an interesting proposal – ask for details).

The machine is easy to operate and permits shift working without problems.
The machine pays ist way quickly thanks to series production in large quantities with consistent quality.
Our fully automatic machine feature all the legally required accident prevention safeguards.
The automatic ornamental ring machine has the answer in particular to the tricky problem of overlap that has such a major effect on ring quality:
exact overlapping of the ring ends and calibration during the welding operation result in a clean and even weld.

Work Sequence

  1. A quietly running circular indexing table actuated by a high-quality and precision-operating stepping gear is responsible for conveying the workpiece to the various stations:
    The strip coming off the coil is exactly measured, cut to length, and transferred to the mounting, which doubles as the forming tool for the subsequent forming operation.
  2. In the welding station, the overlapped ring ends are welded.
    Particularly important: during welding the ring is kept to dimension (calibrated).
    The upright ring is then checked. The welding unit has a centralized water-cooling system.
    Operation with a decentralized unit is however possible on request.
    To supplement this basic machine a twin reel and a strip deburring unit are available on request.
  3. In this station, the ring receives ist final shape.
    This is generally achieved with a roller unit with hydraulic/pneumatic control.
    A cam control is possible for difficult shapes.
  4. In the discharge station, the ring is picked up by a gripper unit, removed from the machine working area, and set down:
    a) Standard method: the ring is set down onto a mandrel
    b) Positioned method: the ring is precisely positioned so that a ring fitting machine can be fitted behind it.

Two vacant stations are provided in addition which can be installed anywhere in the production sequence. They permit additional work processes or interim checks to be implemented. Electrical Control of the Facility The control unit is of the stored-program type and meets every technical requirement of today. A step display permits transmission of error diagnoses. The control console is provided with a mimic diagram enabling even less qualified personnel to pinpoint faults. All switches are designed as illuminated push-buttons. Control console and machine are connected by plug-in leads.
