Abstract: A device for removing tool joint edge burrs on a cap slot edge and an outer rim of a vehicle wheel includes a vehicle wheel positioning system and a cutter system. The vehicle wheel positioning system is used to make a rotating center of a cap seam allowance superposed with that of the cutter system. The cutter system includes a pyramid cutter and four blades, the pyramid cutter is used to remove burrs on the cap slot edge of the vehicle wheel, and the four blades are used to remove burrs on the outer rim of the vehicle wheel.

Abstract: A wheel outer rim fillet dressing device, wherein after a wheel is roughly positioned, an electric cylinder drives a moving plate to descend to an appropriate position, an adjusting cylinder drives a second sliding table to move away from a first sliding table, the first sliding table moves synchronously with the second sliding table under the action of a second gear rack, thus the distance between a precision positioning post on the first sliding table and a precision positioning post on the second sliding table is adjusted, and the precision positioning posts contact a vertical surface of a cap seam allowance of the wheel and hold the wheel tightly. The adjusting cylinder is restarted, and the outer rim fillets can be dressed when the distance between first and second cutters for dressing wheel outer rim fillets is adjusted to an appropriate position and under the cooperation of the rotating wheel.

Abstract: A device for removing tool joint edge burrs of a wheel comprises a frame, a base, first guide rails, a first movable plate, a first ball screw, a longitudinal motor, a transverse motor, second guide rails, a second ball screw, a movable plate II, an electric cylinder, a mobile roller bed, a circle center measuring sensor, an inner bearing, a shaft, a sleeve, guide keys, a hollow shaft, a pyramid cutter, outer cylinders, a left blade, a right blade and the like. The device is configured to simultaneously remove tool joint edge burrs from an outer rim and a cap slot edge and is used for automatic continuous production; by integrating inner and outer burr removing cutters, not only is the space saved, but also inner and outer independent feeding and independent rotation are realized; the inner and outer cutters have higher coaxiality, and the burr removing effect is improved.

Abstract: A low-pressure mold for improving performance of spokes of an aluminum wheel. The mold is characterized in that cooling air holes in a bottom mold are moved for 10 mm outwards; heat-insulation grooves are formed in positions, 5 mm from the cooling air holes, of a back cavity of the bottom mold, and are 8 mm from the surface of a cavity; and the width of each heat-insulation groove is set to 8 mm. A circumference arrangement range of the heat-insulation grooves needs to be larger than the widths of the spokes, and the number of the heat-insulation grooves is defined by the number of the spokes. Heat-preservation asbestos is arranged in each heat-insulation groove, thereby further strengthening heat-insulation and heat preservation functions. One air hole is added based on the prior art, thereby increasing the cooling area and improving the cooling intensity.

Abstract: Disclosed is a wheel outer rim fillet dressing device, including a rough wheel positioning system, a precision wheel positioning system, a wheel rotating system and a cutter dressing system. After a wheel is roughly positioned, an electric cylinder drives a moving plate to descend to an appropriate position, an adjusting cylinder drives a right sliding table to move right, a left sliding table moves synchronously with right sliding table under the action of a second gear rack, thus the distance between a precision positioning post on left sliding table and a precision positioning post on right sliding table is adjusted, and precision positioning posts contact vertical surface of cap seam allowance of wheel and hold the wheel tightly. The adjusting cylinder is restarted, and outer rim fillets can be dressed when the distance between two dressing cutters is adjusted to an appropriate position and under the cooperation of rotating wheel.

Abstract: A central heat-insulation hole structure for an aluminum wheel low-pressure water-cooling casting mold. The structure includes a top mold and a central heat-insulation hole. A split unit structure including a top mold and central flange loose pieces is changed into a non-split integrated top mold. Besides, a circle of uniformly distributed heat-insulation holes are thrilled in a circumferential direction of the position of a mold split unit parting surface of the original top mold and the central flange loose pieces. The diameter of each heat-insulation hole is 8 mm, the size of a wheel flange defines the number of the heat-insulation holes and the diameter of circumference of the heat-insulation holes distributed in the integrated top mold, and in order to ensure the service life and water cooling and heat insulation effects of the mold, the depth of each heat-insulation hole from the surface of a cavity is more than 20 mm.

Abstract: A low-pressure mold for improving performance of spokes of an aluminum wheel. The mold is characterized in that cooling air holes in a bottom mold are moved for 10 mm in outwards; heat-insulation grooves are formed in positions, 5 mm from the cooling air holes, of a back cavity of the bottom mold, and are 8 mm from the surface of a cavity; and the width of each heat-insulation groove is set to 8 mm. A circumference arrangement range of the heat-insulation grooves needs to be larger than the widths of the spokes, and the number of the heat-insulation grooves is defined by the number of the spokes.
