Background

The prior process flow for reducing the diameter of the metal wire is generally as follows: after the metal wire is subjected to multiple die drawing or rolling processes, the metal wire is reduced in diameter to form a finished product or a semi-finished product.

Rolling is a different process than drawing. In the rolling process, the metal blank passes through the pores of the pair of rotating rollers, and the metal wire rod is reduced in section and increased in length due to the compression of the rollers. The rolling is beneficial to improving the mechanical property of the metal wire.

In a traditional rolling device, a speed reduction motor or a motor is matched with a gearbox to serve as a driving mechanism, and then the driving mechanism drives a roller to rotate through the gearbox. Because the driving mechanism is internally provided with the speed reducer or the gearbox, power can be transmitted to the gearbox only through the speed reducer or the gearbox, energy loss is large, and transmission efficiency is low.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A rolling device of a parallel permanent magnet motor direct-drive rolling box comprises a permanent magnet motor 1, a main transmission shaft 3 and a rolling box 4.

The permanent magnet motor 1 is internally provided with a stator assembly and a rotor assembly, and the stator assembly is fixed on the frame. An encoder 1a is arranged in the permanent magnet motor 1.

One end of the main transmission shaft 3 is fixedly connected with the output end of the permanent magnet motor 1, and the other end of the main transmission shaft is connected with the rolling box 4. Preferably, the main transmission shaft 3 is connected with the output end of the permanent magnet motor 1 through a coupling 2. As another preferred mode, the main transmission shaft 3 and the output end of the permanent magnet motor 1 are of an integrated structure and form a part of the output shaft of the permanent magnet motor 1.

Preferably, the main transmission shaft 3 is fixedly connected with an input rotating shaft of the rolling box 4, and the main transmission shaft 3 drives the input rotating shaft of the rolling box 4 to rotate. As another preferred mode, the main transmission shaft 3 is inserted into the rolling box 4 and fixedly connected with an input gear of the rolling box 4, and in this case, the main transmission shaft 3 corresponds to an input rotating shaft of the rolling box 4.

Further, a first roller 6 and a second roller 7 are arranged in the rolling box 4; the first roller 6 and the second roller 7 are arranged in pairs, and a first roller groove 8 is formed between the first roller 6 and the second roller 7; and the roll shaft of the first roll 6 and the roll shaft of the second roll 7 are both arranged in parallel with the output shaft of the permanent magnet motor 1.

Preferably, the mill box 4 comprises a first rotating shaft 5a, a second rotating shaft 5b, a third rotating shaft 5c, a first gear 5d, a second gear 5e, a third gear 5f, a fourth gear 5g and a fifth gear 5 h; the first gear 5d is fixedly arranged on the main transmission shaft 3; a second gear 5e is fixedly arranged on the first rotating shaft 5a, and the second gear 5e is meshed with the first gear 5 d; the second rotating shaft 5b is provided with a third gear 5f and a fourth gear 5 g; the third gear 5f is meshed with the second gear 5 e; the fourth gear 5g is meshed with a fifth gear 5 h; the third rotating shaft 5c is provided with a fifth gear 5 h.

The rolling direction can be adjusted by setting the relative positions of the third rotating shaft 5c and the second rotating shaft 5 b.

When the synchronous driving device works, the permanent magnet motor 1 drives the main transmission shaft 3 to rotate, so that the first gear 5d is driven to synchronously rotate. The first gear 5d rotates the third gear 5f via the second gear 5 e. Since the third gear 5f, the fourth gear 5g and the first roller 6 are all fixed to the second rotating shaft 5b, the fourth gear 5g and the first roller 6 rotate in synchronization with the third gear 5 f. Meanwhile, the fourth gear 5g drives the fifth gear 5h and the second roller 7 to rotate.
