Embodiment 1

[0046]A high-temperature phosphating tank for automobile hubs, the main body of which is a rectangular tank body 1, and a hub basket 2 is arranged side by side in the middle of the tank body 1. The bottom of the hub basket 2 is a hollow grid 6, and the hub basket 2 An inflatable tube 3 is arranged directly below the inflatable tube 3, and an aeration pan 4 is arranged vertically upward on the inflatable tube 3, and a left spoiler 7 and a right spoiler 8 are respectively arranged on the inner walls of both sides of the tank body 1;

[0047] Wherein the surrounding side walls of the hub basket 2 are provided with buffer mesh pads 5, and the buffer mesh pads 5 and the hub basket 2 are closely fixed together;

[0048] The aeration disc 4 on the inflation pipe 3 directly under the hub basket 2 is evenly arranged directly under the hub basket 2, and an aeration disc 4 is arranged under each hub basket 2;

[0049] The distance between the disk surface of the aeration disk 4 and the b...

Embodiment 2

[0051] A high-temperature phosphating tank for automobile hubs, the main body of which is a rectangular tank body 1, and a hub basket 2 is arranged side by side in the middle of the tank body 1. The bottom of the hub basket 2 is a hollow grid 6, and the hub basket 2 An inflatable tube 3 is arranged directly below the inflatable tube 3, and an aeration pan 4 is arranged vertically upward on the inflatable tube 3, and a left spoiler 7 and a right spoiler 8 are respectively arranged on the inner walls of both sides of the tank body 1;

[0052] Wherein the surrounding side walls of the hub basket 2 are provided with buffer mesh pads 5, and the buffer mesh pads 5 and the hub basket 2 are closely fixed together;

[0053] The mesh diameter of the buffer mesh pad 5 is the same as the diameter of the grid 6 at the bottom of the hub basket 2;

[0054] Furthermore, the buffer mesh pad 5 is a rubber mesh pad with high density and excellent corrosion resistance;

[0055] The hub baskets 2...

Embodiment 3

[0060] When using, first pour the phosphating solution into the tank body 1, pour the phosphating solution to about 5 cm from the edge of the hub basket 2, then put the hub into the hub basket 2, and put the hub vertically into the hub In the basket 2, then turn on the inflation equipment connected to the inflation pipe 3 at the bottom of the hub basket 2, and then use the aeration disk 4 installed on the inflation pipe 3 to inflate and disturb the phosphating solution. The aeration disk 4 and the inflation pipe The inside of 3 is nitrogen gas; the left spoiler 7 and the right spoiler 8 arranged on the inner wall of the tank body 1 cooperate with the role of the upper gas tube 3, so that the phosphating solution can be in the same direction in the tank body 1 according to different directions. Rotate slowly, so that the reaction between the phosphating solution and the hub can be fully increased, so as to achieve full phosphating and increase the phosphating speed.

Abstract

The invention relates to the technical field of hub machining equipment and technologies, in particular to a high-temperature phosphating tank for an automobile hub. A main body of the high-temperature phosphating tank is a rectangular tank body; hub baskets are arranged in the middle position in the tank body side by side; the bottoms of the hub baskets are hollowed-out grids; an inflating pipe is arranged under the nub baskets, and aeration discs are vertically upwards arranged on the inflating pipe; and a left turbulence plate and a right turbulence plate are further arranged on the inner walls of the two sides of the tank body correspondingly. The phosphating tank is subjected to turbulence through the inflating pipe, the contact area and the contact degree between a phosphating solution and the automobile hub are increased, and the acting force of the phosphating solution on the hub is increased; and through the left turbulence plate and the right turbulence plate which are arranged on the inner walls of the tank body and by matching the effect of the inflating pipe, the phosphating solution can rotate in the tank body in the same direction and at different slow speeds, in this way, a reaction between the phosphating solution and the hub can be fully increased, and thus the effects that the function of full phosphating is achieved, and the phosphating speed is increased are achieved.

Description

Technical field: [0001] The invention relates to the field of hub processing equipment and technology, and specifically designs a high-temperature phosphating tank for an automobile hub. Background technique: [0002] The wheel hub refers to the cylindrical metal part in the car tire that is centered on the shaft to support the tire. In layman's terms, it is the part where the axle is installed in the center of the wheel. It is an important part that connects the brake drum (brake disc), the wheel disc and the half shaft. part. [0003] The so-called "tyre" is the rubber part in the "wheel" of the car. It is soft in itself, so the drum-shaped part of the inner profile of the tire that supports the tire and the center is mounted on the shaft is called the hub. The main advantage of steel wheels is that the manufacturing process is simple and the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong.
