[0002] The spoke is a device that protects the rim and spokes of the vehicle wheel. It is characterized by a pair of circular cover plates. The diameter of the cover plates is close to the diameter of the rim. There is a hole in the center of the cover plates that is larger than the wheel's rotating axis. There is an opening at the part of the cover plates close to the edge. There is an annular wheel plate at the edge of the cover plates. The curved surface of the wheel plate can fit tightly with the curved surface of the rim. According to the structure of the spokes, the wheels can be divided into spoke plate type and spoke type. The spoke plate type spokes, retaining rings, rims and valve stem extensions together form the wheel. The spoke plate is a steel round plate, which connects the hub and rim into one, and is mostly made by stamping. The spoke type spokes are composed of steel wire spokes or cast spokes cast integrally with the hub. Mainstream family cars mainly use the spoke plate type spoke structure.

[0003] In the prior art, an alignment mold is used in the process of aligning the outer circle of the wheel spoke. After the alignment mold is used for a long time, the die head or the die core may be worn out. If it is not replaced, deviations will occur in the process of aligning the outer circle of the wheel spoke. However, it is inconvenient to replace the die head and the die core of the existing mold. If the entire mold is replaced, the processing cost will increase.

[0004] For this purpose, a wheel spoke outer circle correction die is proposed. Utility Model Content

At this time, the slider 8 can be slid into the installation port 1. When the slider 8 contacts the other rectangular shell 1304, the rectangular shell 1304 can be loosened. Under the restoring elastic force of the spring 1303, the slider 8 will be limited, and the installation of the core 12 is also the same, so that the die head 9 or the core 12 is installed and positioned. By pulling one of the rectangular shells 1304 upwards and sliding the slider 8 into the installation port 1, the rectangular shell 1304 can be loosened, and pushing the slider 8 will drive the roller 1305 to rotate in the rotating groove, so there is no need to wait for the slider 8 to completely slide into the installation port 1 before loosening it, which improves convenience. By turning the twist handle 1410, the bidirectional screw rod 1402 and the round tube 1403 are driven to rotate, and the two long plates 1405 are driven between the two cylindrical The two long plates 1405 can slide towards or away from each other on the boards 1404, thereby adjusting the distance between the two long plates 1405. When the two long plates 1405 move towards each other, the four fixing rods 1406 and the four plug-in rods 1409 can be driven to move towards each other in pairs of two, and the four plug-in rods 1409 can slide in the four plug-in interfaces 1407 and the four plug-in slots 1408 to fix the slider 1 8, and the slider 2 11 is fixed in the same manner. The stability of the support can be improved by setting the number and orientation of the fixing columns 2, and the effect of buffering and shock absorption can be improved by setting the number of buffer springs 3.
