Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

A spinning machine and a rolling assembly thereof according to an embodiment of the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic view of a rolling assembly of a spinning machine according to an embodiment of the present application, which includes a bracket 110 and a roller 150, as shown in fig. 1.

The support 110 is disposed above the blank and can be driven by the driving device to move along the axial direction of the blank.

It should be noted that the blank in the present application mainly refers to a spoke, the rolling assembly in the present application is mainly applied to the spinning forming of the spoke, the blank, the support 110 and the driving device are structurally arranged from bottom to top, and the support 110 is driven by the driving device to move close to or away from the blank.

In an embodiment, the support 110 is formed in an inverted U-shaped structure, and particularly, the support 110 has a support arm 120 extending toward the blank at a lower portion thereof, and the support arm 120 provides a mounting space for the roller 150.

For example, the two support arms 120 are symmetrically disposed below the bracket 110 and perpendicular to the bracket 110, and the two support arms 120 and the bracket 110 are integrally formed.

An annular connecting part 111 is arranged at the top of the bracket 110, and the bracket 110 is fixedly connected with the driving device through the connecting part 111.

The roller 150 is rotatably connected to the two support arms 120 of the support 110, the axis of the roller 150 is parallel to the top surface of the blank, and the peripheral surface of the roller 150 abuts against the top surface of the blank.

The roller 150 applies pressure through the bracket 110 to press the top surface of the blank, when the blank rotates, the roller 150 is driven to roll under the action of friction force, and the rolling of the roller 150 is utilized to realize the rolling of the top surface of the blank.

In this embodiment, the rollers 150 are uniformly distributed along the circumference of the top surface of the blank to ensure that the top surface of the blank is uniformly pressed.

For example, a support shaft 140 is fixed between the two support arms 120, and the roller 120 is rotatably coupled to the support shaft 140, and the support shaft 14 is parallel to the top surface of the billet.

In order to improve the stability of the whole structure, a positioning plate 130 is disposed between the two support arms 120, the positioning plate 130 is parallel to the support arms 120 and is located at the middle position of the two support arms 120, and a support shaft 140 passes through both the support arms 120 and the positioning plate 130.

It should be noted that the positioning plate 130 divides the installation space between the two support arms 120 into two parts, and the rollers 150 are symmetrically disposed on both sides of the positioning plate 130, and the positioning plate 130 provides a supporting function for the support shaft 140, and at the same time, improves the strength of the overall structure.

For example, the positioning plate 130 is integrally formed with the bracket 110.

It can be understood that, the peripheral surface of the roller 150 in the present application is pressed against the top surface of the blank and is driven by the blank to rotate, and compared with the design of pressing the top surface of the blank by using the pressing plate structure in the related art, the roller in the present application generates less friction force on the top surface of the blank, and the rolling form can better ensure the flatness of the top surface of the blank.

A spinning machine according to embodiments of the present application includes a roll stack of a spinning machine according to embodiments of the present application. Because the rolling assembly of the spinning machine has the beneficial technical effects, the rolling process of a subsequent rolling machine can be reduced, and the working efficiency of blank forming is improved.
