[0015] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of a hub blank punching and forming device provided by the utility model. The hub blank punching and forming device includes a workbench 10, a positioning portion 20 arranged on the workbench 10, a punching portion 30 arranged on the workbench 10 and located on one side of the positioning portion 20, and a pressing device 40 arranged on the workbench 10. It can be imagined that the hub blank punching and forming device also includes some other functional structures, such as door panels, electrical boxes, etc., which are well known to those skilled in the art and will not be repeated here.

[0017] The workbench 10 is used to set the positioning part 20, the punching part 30 and the pressing device 40. A material discharge trough 11 is provided on the workbench 10 for discharging waste materials. It should be a technology well known to industry personnel and will not be described in detail here.

[0018] The positioning portion 20 includes a base 21 fixedly disposed on the workbench 10, a positioning seat 22 fixedly disposed on the base 21, and a punch 23 embedded in the positioning seat 22. A cavity 24 is disposed between the base 21 and the workbench 10 for use with the punching portion 30. The positioning seat 22 is used to fix the wheel hub blank, and the punch 23 is used to cooperate with the punching portion 30 to perform the punching and shaping step on the wheel hub blank. The outer contour of the punch 23 is stepped. And a short punch 25 and a long punch 26 are respectively disposed on the two steps of the punch 23 at one end facing the punching portion 30. The short punch 25 and the long punch 26 are both used for use with the punching portion 30, and will be described below in conjunction with the punching portion 30.
