Embodiment Construction

[0038] With the help of the following figure 1 Preferred embodiments are described.

[0039] figure 1 The structure of the machine is shown schematically, with a drive 10 with an electric motor, a work element 20 to be driven by the drive 10 and a stop 30 for braking the machine. The stop device 30 has an electric brake device 40 and a mechanical stop device 50 .

[0040] The power mechanism 20 to be driven by the drive mechanism 10 can be implemented in many ways, for example as one or more work rolls and / or idlers in a rolling mill, tension or transport rolls, winding equipment, coating equipment, fly Shears, winches in vertical or horizontal storage containers, etc.

[0041] The electric motor of the drive mechanism 10 , preferably a synchronous motor or a torque motor, has a rotor 11 and a stator 12 , which are preferably fastened directly on the frame or housing of the power mechanism 20 . The rotor 11 is connected to the shaft of the power mechanism 20 , whereby the ...

Abstract

Method and device for braking a machine with a drive (10) with an electric motor, preferably a direct drive, and a work unit (20), preferably a work unit (20) for metalworking, wherein the drive The mechanism (10) is capable of driving the shaft of the work mechanism (20) in rotation, and the method comprises: braking the machine frictionlessly by means of an electric braking device (40) from a working state to a standstill in which the work mechanism The shaft of (20) is substantially at rest; the machine is mechanically locked to a standstill by means of and by operation of the mechanical stop device (50); wherein the electric brake device (40) and the mechanical stop device (50) are controlled In order that basically all the kinetic energy in the working state is converted by the electric brake device (40), while the mechanical stop device (50) only works in the machine's stop state.

Description

technical field [0001] The present invention relates to a method and a device for braking a machine having a drive mechanism with an electric motor, preferably a direct drive mechanism, and a power mechanism for metalworking. Background technique [0002] In different fields of metal processing, for example in rolling mills and embossing machines, there is a technical separation between mechanical devices or tools, such as rolls, idlers or tensioning rolls, and electric drives. This separation has historical reasons and can result in a suboptimal interface between mechanical and electrical equipment. [0003] Transmissions, couplings, brakes, cardan shafts and other mechanical components between the drive mechanism and the power mechanism to be driven are not conducive to better integration and related advantages such as improvements in energy efficiency and reliability as well as equipment miniaturization, etc. [0004] Many work mechanisms in the metalworking industry ar...
