Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, the existing hub structure includes:

[0032] The rim 11 is assembled with the tire and supports the wheel part of the tire;

[0033] rim 12, the part of the rim that holds and supports the direction of the tire;

[0034] The bead seat 13 is in contact with the bead of the tire and supports the rim portion maintaining the radial direction of the tire;

[0035] And groove bottom 14, for the convenience of tire assembly and disassembly, leave the pit etc. of certain degree of depth and width on the wheel rim.

[0036] Such as Figure 2-Figure 6 As shown, the embodiment of the present invention provides a hub stretching machine, including a hub heating device 2 and a hub stretching device 3, the hub heating device 2 is used to he...

Abstract

The invention discloses a hub stretching machine, comprising a hub heating device and a hub stretching device, the hub heating device is used to heat the hub to a predetermined temperature; the hub stretching device includes a rotating base, a stretching wheel and A surface heating device; the rotating base is used to fix and rotate the hub; the surface heating device is used to heat the surface of the hub during the stretching process of the hub. The wheel hub stretching device of the present invention includes a stretching wheel that is inclined downward at a certain angle relative to the edge of the wheel hub. The stretching wheel can rotate freely relative to the rotating shaft on the stretching lifting seat and follow the stretching The lifting seat moves up and down to realize the stretching of the wheel hub, and molds the wheel hub in accordance with the outer surface contour of the rotating base to stretch the wheel hub into a predetermined thickness and shape.

Description

technical field [0001] The invention relates to a hub processing machine, in particular to a hub stretching machine. Background technique [0002] The existing wheel hub production method is mainly one-piece casting molding. This method has simple process, low production cost, and the formed wheel hub has good rigidity and durability. [0003] With the development of the automobile industry, people demand more lightweight and high mechanical strength wheels. In order to achieve the above object, the method of stretching the wheel hub after casting and molding can be adopted. The metallographic arrangement of the wheel hub is more uniform after stretching. Compared with casting molding, the wheel hub of stretch molding is lighter in weight under the same specification, and its rigidity and surface hardness are also better, which can effectively reduce the weight of the whole vehicle and make the car run more smoothly. But, the automatic stretching machine of wheel hub does...
