The purpose of the utility model can be realized by the following technical proposal: a zero-offset electric vehicle wheel hub shaping device comprises two guide pillars, an upper base plate, a lower base plate, a template and mold cores, wherein the template and the mold cores are identical in structure and are respectively installed on the upper base plate and the lower base plate, the lower base plate and the bottoms of the guide pillars are mutually fixed, the upper base plate is movably sleeved on the guide pillars and is connected with hydraulic equipment to realize up-and-down movement, the two mold cores are respectively fixed with the upper base plate and the lower base plate, the zero-offset electric vehicle wheel hub shaping device is characterized in that the mold cores are of a circular table structure, shaping mold sleeves matched with the mold cores in structure are arranged outside the mold cores, gaps are formed between the shaping mold sleeves and the template and can slide up and down through a plurality of pin shafts, thrust blocks are fixed on two sides of the template, and thrust springs are arranged between the shaping mold sleeves.

The principle of the zero-offset electric vehicle hub shaping device is as follows: the hub workpiece sleeve needing to be shaped is arranged on the shaping die sleeve below, the upper side and the lower side of the hub workpiece are symmetrical due to the fact that the hub workpiece is a zero-offset hub, then the upper base plate is driven to press downwards through hydraulic equipment to enable the shaping die sleeve above to enter the other side of the hub, along with downward pressure, the shaping die sleeve connected with the die core matching pin shaft of the circular truncated cone structure can be touched to enable the shaping die sleeve of the split structure to expand radially, the hub is shaped, further a buffering effect can be achieved when the hub is shaped, the shaping die sleeve is aligned with the center of the hub, thrust springs radially arranged in a thrust block matching mode are arranged on two sides of the die plate, the buffering effect is achieved when the shaping die sleeve expands, and the contact surface of the hub is prevented from being scratched.

In the zero-offset-distance electric vehicle hub shaping device, the upper end and the lower end of the shaping die sleeve are both provided with an annular groove, and an extension spring is clamped in the annular groove.

In the zero-offset electric vehicle hub shaping device, a gap is formed between the lower bottom plate and the template, and a compression spring is arranged.

Compared with the prior art, the zero-offset electric vehicle hub reshaping device effectively buffers the reshaping die sleeve when expanding through the cooperation of the thrust spring, the extension spring and the compression spring, effectively prevents the surface from being scratched when the hub is reshaped, and can increase the die closing speed to a certain extent.
