Embodiment 1

[0038] see Figure 1-8 As shown, a rust-proof treatment process for an electric vehicle frame includes the following steps:

[0039] Step 1. The first electric push rod 107 pushes the movable rack 103 from the top of the lifting rack 102 to the outside of the processing box 10. The slider 106 at the bottom of the movable rack 103 slides inside the chute 111 on the top of the lifting rack 102 to ensure the movable rack 103 Stability during the sliding process, then place the welded electric vehicle frame on the top of the movable frame 103, and the two sides of the frame are respectively located in the placement slots 104 inside the two placement frames 110, and then pass through the placement slots. The limit blocks 105 inside 104 limit the two sides of the frame, so that the frame can be stably placed on the top of the movable frame 103, control the first electric push rod 107 to drive the shaft to reset, and send the frame into the processing box 10 internal;

[0040] Step...

Embodiment 2

[0045] see Figure 1-8 As shown, the anti-rust treatment device used in the anti-rust treatment process of the electric vehicle frame in the present invention includes a treatment box 10, wherein a movable partition is arranged inside the treatment box 10, and a baffle is arranged inside the movable partition. When the rust removal treatment is performed, both sides of the inside of the treatment box 10 are separated by baffles and movable partitions. A partition curtain 20 is provided on the left side of the processing box 10 , a fixing box 30 is provided on the right side inside the processing box 10 , a placing mechanism is provided on the lower part of the left side inside the processing box 10 , and an upper left side inside the processing box 10 is provided. Drying mechanism, a sandblasting mechanism is arranged on the back of the inside of the processing box 10, a feeding mechanism is arranged on the top of the processing box 10, and a processing mechanism is arranged i...

Embodiment 3

[0052] In the present invention, the drying mechanism includes an air inlet duct 301 , the front and rear sides of the top of the processing box 10 are provided with mounting brackets 302 , and the bottoms of the two mounting brackets 302 are provided with rotating grooves 303 , and the interior of the rotating grooves 303 is rotated and provided with hot air knife 304, and the inside of the hot air knife 304 is communicated with one end of the air inlet pipe 301, one side of the mounting frame 302 is provided with a first motor 305, and one end of the output shaft of the first motor 305 is fixedly connected to one side of the hot air knife 304;

[0053] In use, compressed hot air is blown into the hot air knife 304 through the air inlet pipe 301, and finally the compressed hot air is blown to the surface of the frame through the hot air knife 304, and at the same time, the hot air knife 304 is driven to rotate by the output shaft of the first motor 305. The inside of the groov...

Abstract

The invention relates to the technical field of anti-rust treatment, in particular to an electric vehicle frame anti-rust treatment process which comprises the following steps: carrying out overall rust removal treatment and cleaning treatment on the surface of a frame, then soaking the frame by using a water-based anti-rust agent, and then carrying out rapid drying treatment to finish the anti-rust treatment of the frame. The sand blasting mechanism and the drying mechanism are arranged in the treatment box, rust at the welding position of the surface of the electric vehicle frame is subjected to rust removal treatment, the surface of the frame is kept clean in cooperation with the drying mechanism, then the frame is turned over through the feeding mechanism, and rust removal treatment on the whole surface of the frame is completed; the vehicle frame subjected to surface rust removal treatment is conveyed into a liquid medicine box in a fixing box, the vehicle frame is soaked with a water-based antirust agent, and then the surface of the vehicle frame is rapidly dried through a drying mechanism, so that the water-based antirust agent forms a compact protective film on the surface of the vehicle frame, oxygen and water in air are effectively prevented from making contact with the surface of steel, and the service life of the vehicle frame is prolonged. The purpose of long-term rust prevention is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-rust treatment, in particular to a process for anti-rust treatment of an electric vehicle frame. Background technique [0002] The frames of electric vehicles are generally made of iron pipes, which have poor corrosion resistance. Although the traditional painting and anti-rust process has a good anti-rust effect, it has great limitations. Aging and rubbing of the paint surface causes the anti-rust paint to peel off, lose the anti-rust ability and lead to the rust of the frame, which not only affects the riding safety, but also has a negative impact on the manufacturer; [0003] In the existing Chinese utility model patent CN212189821U, an anti-rust treatment device for the frame of an electric vehicle is proposed. In this solution, the whole frame is immersed in the anti-rust liquid to complete the anti-rust treatment of the entire frame. After the frame is welded, there are rust spots formed by ox...
