Abstract
Description
Technical Field
[0001] This utility model relates to the field of pickling technology for wheel rims, specifically to a pickling device for wheel rims. Background Technology
[0002] Pickling is an important surface treatment process in the production of wheel rims, used to remove oxide scale and rust from the rim surface. Currently, the common technique involves immersing the rim in a pickling tank for pickling, and then using a crane or hook to lift the rim and transfer it to a nearby cleaning tank for rinsing.
[0003] However, during the aforementioned transfer process, residual pickling solution dripping from the wheel rims will drip and splash uncontrollably. This not only wastes acid and pollutes the workshop environment, but more seriously, the highly corrosive acid will splash onto equipment, the ground, and workers, posing a significant safety hazard and accelerating the corrosion and aging of other equipment in the workshop.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] A pickling device for wheel rims includes: a pickling tank 10, a draining mechanism 20, and a hoisting mechanism 30.
[0019] Pickling tank 10 is used to hold pickling solution to soak and pickle the steel wheel rims.
[0020] The draining mechanism 20 is located on one side of the pickling tank 10 and connected to the pickling tank 10. It includes a draining trough 201, one end of which is connected to the pickling tank 10. A rotating draining platform 202 is provided in the draining trough 201 for placing wheel rims for draining. The draining platform 202 is driven by a rotation drive mechanism. The draining platform 202 is provided with a clamping and fixing component for the wheel rims.
[0021] The hoisting mechanism 30 is used for hoisting wheel rims and includes a track 301 horizontally positioned above the pickling tank 10 and the drain trough 201, with movable lifting devices on the track 301.
[0022] The wheel rim is lifted by a hoist and transported to the pickling tank 10 for immersion and pickling. It remains suspended on the hoist throughout the pickling process. After pickling, it is lifted to the draining trough 201 and placed on the draining platform 202. The hoist is removed and secured using clamping components. The drive mechanism rotates the draining platform 202 at high speed, using centrifugal force to fling out any remaining pickling solution from the wheel rim. Finally, the drained wheel rim is lifted away by the hoist. This invention features a draining mechanism 20 connected to the side of the pickling tank 10. After pickling, the wheel rim is drained directly through the draining mechanism 20, removing any residual pickling solution and preventing spillage.
[0023] In a preferred embodiment, a rotating support column 203 is fixedly mounted at the lower center of the draining platform 202 and rotatably installed at the bottom of the draining trough 201. A first sprocket 204 is fixedly mounted on the rotating support column 203. A first motor 206 is mounted on the outer wall of the draining trough 201. A second sprocket 205 is mounted on the output end of the first motor 206. The first sprocket 204 and the second sprocket 205 are connected by a chain. A through hole for the chain to pass through is provided on the side wall of the draining trough 201.
[0024] The chain drive connects the first sprocket 204 and the second sprocket 205, thereby driving the rotating support column 203 to rotate via the motor. The lower end of the rotating support column 203 is rotatably mounted on the bottom of the drain trough 201 via a bearing, and the upper end of the rotating support column 203 is fixedly connected to the drain platform 202, thereby driving the drain platform 202 to rotate via the first motor 206.
[0025] In a preferred embodiment, the bottom of the drain trough 201 is inclined, with the end of the bottom of the drain trough 201 that is connected to the pickling tank 10 having a lower height and the end that is away from the pickling tank 10 having a higher height. The drain trough 201 is connected to the upper end of the pickling tank 10, and a notch 207 is provided on the side wall of the drain trough 201 near the pickling tank 10 to communicate with the pickling tank 10. The lower end of the notch 207 is flush with the bottom of the drain trough 201.
[0026] The pickling liquid splashed off the wheel rim flows back into the pickling tank 10 along the sloping bottom of the drain trough 201.
[0027] In a preferred embodiment, the clamping and fixing assembly includes a central column 2081 protruding from the upper end of the upper draining platform 202. The central column 2081 is located at the rotation center of the draining platform 202. A threaded hole is provided at the upper end of the central column 2081. A pressure plate 2082 is provided above the central column 2081. The pressure plate 2082 is arranged in a "+" shape. A connecting hole is provided at the center of the pressure plate 2082. A screw 2083, which is screwed into the threaded hole, passes through the connecting hole. A pressure block 2084 that can press against the upper end of the pressure plate 2082 is fixed on the screw 2083. A rotating handle 2085 is fixed at the top end of the screw 2083.
[0028] When the wheel rim is placed on the draining platform 202, the center post 2081 passes through the center hole of the wheel rim. Then, the pressure plate 2082 is pressed onto the upper end of the wheel rim. The screw 2083 passes through the connecting hole of the pressure plate 2082 and is screwed into the threaded hole at the upper end of the center post 2081 for locking. The pressure block 2084 on the screw 2083 presses onto the pressure plate 2082, thereby pressing the pressure plate 2082 onto the wheel rim. The wheel rim is fixed by the combined action of the pressure plate 2082 and the draining platform 202.
[0029] In a preferred embodiment, a first rubber pad layer is fixedly provided on the upper surface of the draining platform 202, and a second rubber pad layer is fixedly provided on the lower surface of the pressure plate 2082.
[0030] The first and second rubber pads can prevent the draining platform 202 and the pressure plate 2082 from making hard contact with the wheel rim and causing scratches on the surface of the wheel rim. In addition, they can increase the friction between them and the wheel rim, thereby further strengthening the clamping effect on the wheel rim and making it more secure.
[0031] In a preferred embodiment, the lifting device includes a crane 302 that moves on a track 301. The crane 302 is driven to move by a moving mechanism, which employs existing technology where the crane 302 moves on a gantry. A rotating take-up reel 303 is mounted on a bracket at the lower end of the crane 302. The take-up reel 303 is driven to rotate by a second motor 304 mounted on the bracket. A cable 305 is wound on the take-up reel 303. Four branch ropes 306 are connected to the free end of the cable 305. A hook 307 is connected to the end of each branch rope 306.
[0032] The hook 307 is hooked onto the wheel rim, and the second motor 304 drives the take-up reel 303 to rotate, thereby raising and lowering the wheel rim.
[0033] In a preferred embodiment, a rubber sleeve is fitted onto the hook 307.
[0034] The rubber sleeve prevents the hook 307 from scratching the surface of the wheel rim and increases friction to prevent the hook 307 from slipping when lifting the wheel rim.
[0035] In a preferred embodiment, the lifting device is provided in two sets.
[0036] One set of lifting equipment is used to lift the wheel rims for pickling and then transport them to the draining platform 202. Another set of lifting equipment is used to transport the drained wheel rims from the draining platform 202 to other processes. This division of labor between the two sets of lifting equipment is more efficient than using a single set to complete the entire process.
