Embodiment 1

[0036] Such as Figure 1~4As shown, this embodiment provides a frameless combined permanent magnet synchronous motor direct-driven plate rolling machine, including a frame 1, an upper pressure roller 4, two lower pressure rollers 10 and a driving device; the lower pressure roller The diameter of 4 is larger than the upper pressure roller 10; the upper pressure roller 4 is located between the two lower pressure rollers 10 and is connected to the upper end of the lifting device 10, and the two ends of the upper pressure roller 4 pass through sliding bearings 3 is installed on the frame 1, wherein one end of the upper pressing roller 4 passes through the sliding bearing 3 and is connected with a balancing device 5, and the lifting device 11 is installed at both ends of the upper pressing roller 4 , the lower ends of the two lifting devices 11 are fixedly connected to the driving device, and the two driving devices simultaneously drive the corresponding lifting device 11; one end ...

Embodiment 2

[0040] Such as Figure 5 As shown, the preferred embodiment of the present invention is to provide a plate bending machine directly driven by a frameless combined permanent magnet synchronous motor. The structure and working principle of this embodiment are similar to those of embodiment 1, but different from embodiment 1 The difference is that the lifting device 11 is installed at both ends of the upper pressing roller 4 in this embodiment, and the lower ends of the two lifting devices 11 are connected through a worm gear 12, and one of the lifting devices is connected to the lifting device 12. The frameless combined permanent magnet synchronous motor 9 is connected; the worm gear 12 includes a support base 13, a clutch 14, a support 15, a transmission rod 16 and a support base 13 connected in sequence; power is transmitted through the worm gear 12 .

Embodiment 3

[0042] Such as Figure 6-8 As shown, the preferred embodiment of the present invention is to provide a frameless combined permanent magnet synchronous motor direct-driven plate bending machine. The structure and working principle of this embodiment are similar to those of embodiment 1 or 2, while the The difference between or 2 is that there is an air gap 6 between the stator base and the rotor base in this embodiment, and the two ends of the air gap 6 are respectively provided with at least two layers of sealing rings 61 arranged in parallel. There is a hook-shaped structure 62 in the outer ring and the inner ring of the sealing ring 61, and elastic balls 63 distributed in a ring are embedded in the connection between the hook-shaped structure 62 and the body of the sealing ring 61; The free ends of the hook structures 62 are located in the space formed by the plurality of sealing rings 61 , and the hook structures 62 are alternately in free contact with the stator base and t...

Abstract

The invention discloses a plate rolling machine directly driven by a frameless combined type permanent magnet synchronous motor. The plate rolling machine comprises a rack, an upper compression roller, lower compression rollers and driving devices; the driving devices are used for providing power for the upper compression roller and the lower compression rollers; each driving device is a framelesscombined type permanent magnet synchronous motor which comprises a stator component and a rotor component; each stator component is fixedly installed on the rack; each rotor component is directly connected with a driven part; each stator component comprises fan-shaped blocks formed by the stator windings and stator cores which are integrally molded in a casting manner; and a plurality of fan-shaped blocks are annularly distributed and / or circumferentially distributed on the corresponding rotor component. According to the plate rolling machine disclosed by the invention, the frameless combinedtype permanent magnet synchronous motor is adopted as a direct driving motor for the plate rolling machine, so an intermediate driving link of a transmission part is reduced, the driving mode and thestructure are simplified, the driving efficiency is improved, direct driving of the plate rolling machine is realized, and energy loss is reduced.

Description

technical field [0001] The invention relates to the field of plate rolling equipment, in particular to a plate rolling machine directly driven by a frameless combined permanent magnet synchronous motor. Background technique [0002] The plate rolling machine is a kind of equipment that uses work rolls to bend and form the sheet metal. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate rolling machine is to move the work roll through the action of hydraulic pressure, mechanical force and other external forces, so that the plate is bent or rolled into shape. According to the rotation movement and position changes of the work rolls of different shapes, oval parts, arc parts, cylindrical parts and other parts can be processed. In the prior art, the upper roller of the plate rolling machine is at the central symmetrical position of the two lower rollers, and the hydrau...
