Description

Technical Field

[0001] The invention relates to the field of aluminum alloy wheel manufacturing, in particular to an aluminum alloy wheel shaping device. Background Art

[0002] Aluminum alloy wheels are manufactured according to the following processes: aluminum ingot smelting, low-pressure casting of blanks, blank heat treatment, machining, surface spraying, product packaging, etc. Among them, the purpose of the heat treatment process is to improve the mechanical properties of aluminum alloy wheels, enhance the corrosion resistance of aluminum alloy wheels, improve the machining performance, and obtain the stability of product size. However, during the heat treatment process, due to the changes in the internal microstructure, internal and external stresses are released, thus forming the deformation of the blank of the aluminum alloy wheel. Specifically, during the heat treatment and subsequent machining process, the casting will change in shape and size, which will bring unnecessary effects to all processes. Deformation is inevitable. Although the deformation can be minimized by reasonably adjusting the specific process parameters of the heat treatment, the deformation will always exist.

[0003] In order to provide the best possible aluminum alloy blanks for the subsequent machining process, the aluminum alloy blanks must be corrected to restore the deformation to the smallest possible state. Summary of the invention

DETAILED DESCRIPTION

[0023] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference below Figure 1-Figure 5 The aluminum alloy wheel shaping device according to the embodiment of the present invention is described in conjunction with the embodiment.

[0026] An aluminum alloy wheel correction device includes a frame 1, a reduction motor 2, an upper turntable 6, a hydraulic rotary joint 5, a clamping cylinder 8, a pressure claw 10, a tapered roller 13, a bearing assembly 14, a guide column 16, a lifting base 18, a guide plate 17, a lifting cylinder 22, a positioning cylinder 19, a positioning cone 20, a bearing seat 11, a roller 12 and other structures. The reduction motor 2 is installed on the top of the frame 1 by bolts, the upper turntable 6 is connected to the reduction motor 2, and the reduction motor 2 can drive the upper turntable 6 to rotate. The hydraulic rotary joint 5 is fixed to the frame 1 with bolts and connected to the upper turntable 6. The clamping cylinder 8 is installed on the upper turntable 6 by screws 9. The clamping cylinder 8 and the hydraulic rotary joint 5 are connected by an oil pipe 7. The pressure claw 10 is installed on the clamping cylinder 8. The tapered roller 13, the bearing assembly 14, and the guide column 16 are assembled together. There are three sets in total, which are respectively installed on the lifting base 18 with bolts. The guide column 16 passes through the guide plate 17 to play a guiding role. There are also three lifting cylinders 22, which are respectively installed at the bottom of the frame 1 and can drive the lifting base 18 to move up and down. The positioning cylinder 19 is installed at the bottom of the frame 1, and the positioning cone 20 is installed on the piston rod of the positioning cylinder 19. The bearing seat 11 is fixed on the frame 1, and the roller 12 is connected to the bearing seat 11. Multiple rollers 12 and the bearing seat 11 form a roller conveyor system.

[0027] During operation, the roller conveyor system composed of the roller 12 and the bearing seat 11 will transport the aluminum alloy wheel 21 to the central working area of ​​the equipment ( Figure 2 ).

[0028] Next, the positioning cylinder 19 drives the positioning cone 20 to move upward, lifting the aluminum alloy wheel 21 until it contacts the upper turntable 6; then the clamping cylinder 8 drives the pressing claw 10 to rotate and clamps the wheel 21 with the pressing claw 10 ( Figure 4 ).

[0029] When the pressing claw 10 presses the wheel 21, the positioning cylinder 19 drives the positioning cone 20 to descend to the initial position ( Figure 5 ).

[0030] Then, the reduction motor 2 drives the upper turntable 6 to rotate slowly. Since the hydraulic rotary joint 5 is installed, the pressing claw 10 is still in the state of pressing the wheel 21. At the same time, the three lifting cylinders 22 synchronously drive the lifting base 18 to move upward, and drive the three sets of tapered rollers 13, the bearing assembly 14, and the guide column 16 to move upward until the tapered roller 14 contacts the inner wall of the wheel 21 ( Figure 5 ).

[0031] During the upward movement of the lifting cylinder 22, the aluminum alloy wheel 21 rotates slowly; at the same time, since the tapered roller 13 has a bearing assembly 14 inside, the tapered roller 13 also rotates. Therefore, the lifting cylinder 22 causes the three tapered rollers 13 to roll and squeeze the inner cavity of the aluminum alloy wheel 21 outward, causing it to deform, thereby achieving the effect of correcting the shape.

[0032] Compared with the prior art, the aluminum alloy wheel shaping device of the present invention has the following advantages:

[0033] The invention can meet the need for aluminum alloy wheel shape correction and has the characteristics of simple structure and easy operation.
