Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The present invention will be further explained below with reference to specific embodiments.

[0035] like Figures 1-3 As shown in the figure, the front support mechanism of the main shaft of the flattening machine provided in this embodiment includes: a support component 1 and a drive component 2;

[0036] The support assembly 1 is provided with a support block 11, which can be rotatably approached and moved away from the underside of the main shaft 4 of the flattening machine, for supporting the main shaft 4 when the rim 5 is flattened and for unloading the rim 5 after flattening.

[0037] Drive component 2 is used to drive support block 11 to rotate;

[0038] The support component 1 is fixedly installed at the front of the flattening machine body 3.

[0039] The rotatable support block 11 provides upward support to the front of the main shaft 4 when the rim 5 is flattened, reducing the pressure on the front of the main shaft 4 when it is pressed down by the upper pressure head, thus preventing cracks or breakage of the main shaft 4 and improving its service life. This also improves the flattening quality of the rim 5. At the same time, it reduces equipment vibration and lowers environmental noise.

[0040] The support assembly 1 also includes a support 12, which is fixedly mounted on the body 3 of the flattening machine, and the support block 11 is rotatably mounted on the support 12.

[0041] Furthermore, the drive assembly 2 includes a rotating shaft 21, which is rotatably disposed on the support 12, and the middle part of the rotating shaft 21 is coaxial and fixedly sleeved on the lower part of the support block 11.

[0042] The lower part of the support block 11 is inserted into the middle of the support 12.

[0043] like Figure 4 As shown, in this embodiment, the support block 11 and the rotating shaft 21 are fixedly connected by a flat key 13, which is used to drive the support block 11 to rotate.

[0044] Both ends of the rotating shaft 21 extend into the support 12, and rolling bearings 14 are provided between the rotating shaft 21 and the support 12 to prevent jamming between the rotating shaft 21 and the support 12 due to rotational friction, thereby improving the rotational stability of the rotating shaft 21.

[0045] The connection method of the flat key 13 is simple and highly reliable, ensuring that the support block 11 accurately reaches the vertical support position and returns to the horizontal position during rotation.

[0046] like Figure 5 As shown, a limiting surface 111 is provided on one side of the support block 11 for limiting the vertical support position of the support block 11;

[0047] The setting of the limiting surface 111 ensures the limitation of the vertical position of the support block 11, and improves the accuracy and stability of the support block 11 in the supporting position;

[0048] The top of the support block 11 is provided with an arc surface 113 to avoid interference between the support block 11 and the main shaft 4 of the flattening machine when the support block 11 rotates, thus ensuring the smooth positioning and reset of the support block 11.

[0049] In addition, the support block 11 has a first keyway 112 adapted to the flat key 13.

[0050] A rotating rod 22 is fixedly installed at one end of the rotating shaft 21 to drive the rotating shaft 21 to rotate.

[0051] like Figures 6-8 As shown, in this embodiment, a flat platform 211 is provided at one end of the rotating shaft 21 connected to the rotating rod 22 along the axial direction, and a flat groove 221 adapted to the flat platform 211 is provided at one end of the rotating rod 22 connected to the rotating shaft 21. This is used for circumferential limiting when the rotating shaft 21 and the rotating rod 22 are connected, ensuring the synchronous rotation of the rotating shaft 21 and the rotating rod 22.

[0052] The flat platform 211 has a screw hole along the axial direction at one end, and the rotating rod 22 has a through hole 222 for fastening screws. By fastening the rotating shaft 21 and the rotating rod 22, the stability of the axial connection between the rotating shaft 21 and the rotating rod 22 is improved.

[0053] In addition, a second keyway 212 adapted to the flat key 13 is provided on the rotating shaft 21.

[0054] The other end of the rotating rod 22 is connected to a telescopic mechanism.

[0055] The telescopic mechanism can be a telescopic cylinder, a telescopic hydraulic cylinder, or an electric telescopic rod, etc.

[0056] In this embodiment, the telescopic mechanism is a telescopic cylinder 23;

[0057] The body of the telescopic cylinder 23 is pivotally connected to the machine body 3 of the flattening machine; the telescopic end of the telescopic cylinder 23 is fixedly provided with a connecting joint 24, and the other end of the connecting joint 24 is hinged to one end of the rotating rod 22 through a pin.

[0058] In addition, the telescopic cylinder 23 is equipped with an electrical limit mechanism for limiting the extension of the telescopic mechanism, thereby assisting the support block 11 in reaching the limit position.

[0059] Specifically, when the rim 5 is being fed, the support block 11 is in a horizontal position, facilitating the smooth feeding of the rim 5. After the rim 5 is placed on the flattening die of the main shaft 4, the telescopic end of the telescopic cylinder 23 extends, driving the rotating rod 22 to rotate clockwise. At the same time, the rotating rod 22 drives the support block 11 to rotate clockwise. Through the limiting surface 111 of the support block 11 and the electrical limiting of the telescopic cylinder 23, the support block 11 accurately reaches the support position to support the flattening main shaft 4. After the rim 5 is flattened, the telescopic cylinder 23 retracts, and the rotating rod 22 and the support block 11 rotate counterclockwise to a horizontal position, realizing the smooth unloading of the rim 5.

[0060] The front support mechanism for the main shaft of a flattening machine provided by this utility model has the following advantages:

[0061] 1. A support block is installed at the front of the flattening machine to support the front end of the main shaft, which improves the load-bearing capacity of the main shaft, avoids cracks or breakage caused by cantilever at the front end of the main shaft, improves the service life of the main shaft, and thus improves the flattening quality of the rim.

[0062] 2. The front support mechanism of the main shaft of this flattening machine has a compact structure, is easy to install, and is simple to operate.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
