Problems solved by technology

[0003] Passivation treatment is a kind of anti-rust treatment for the plane of the shell. Passivation is to use the oxidation-reduction reaction between the oxidizing substance in the passivation solution and the metal to promote the formation of a layer of metal oxide on the metal surface to transform the metal surface. In order to be in a state that is not easy to be oxidized, the oxide layer is often damaged at the weld position when welding before the shell plane and needs to be re-passivated. In the prior art, the weld position is often covered by the box, and then the cavity of the weld The room is filled with passivation solution to passivate the welds, but the welds on the plane of the shell are often longer, and the debris generated by the actual passivation will be spread on the bottom, making the actual passivation effect poor

Embodiment 1

[0028] refer to Figure 1-3 , a shell plane weld passivation device for mechanical processing, comprising a passivation piece 1, a passivation cavity is opened at the bottom of the passivation piece 1, and a liquid inlet pipe 2 and a liquid outlet pipe are connected to the top of the passivation piece 1 3. Both sides of the top outer wall of the passivation piece 1 are fixed with a connecting piece 4, and the top of the connecting piece 4 is connected with a moving guide rail 5. Both positions are fixed with fixed blocks 7, and both sides of the bottom outer wall of the passivation part 1 are fixed with spacer pads 8, and both ends of the bottom outer wall of the passivation part 1 are fixed with smoothing pads 9;

[0029] When the device is in use, the lifting frame 6 is used to cover the passivation part 1 at the position of the weld, and the passivation liquid is circulated in the passivation chamber through the liquid inlet pipe 2 and the liquid outlet pipe 3, and the devi...

Embodiment 2

[0035] refer to Figure 1-5 , a shell plane weld passivation device for mechanical processing, a flow guide 16 is fixed on the top inner wall of the passivation piece 1, and the bottom outer wall of the flow guide 16 is set in an arc-shaped structure with an upward arch at the middle position, and the The liquid pipe 3 is fixed at the position corresponding to the top of the passivation piece 1 and the middle of the guide piece 16. There are two liquid inlet pipes 2, and the two liquid inlet pipes 2 are respectively fixed at the two ends of the passivation piece 1, so that the blunt The passivation solution in the passivation part 1 enters and fills from both ends and is drawn out from the middle position. Cooperating with the overall movement of the passivation part 1 and the diversion effect of the guide part 16 on the passivation liquid and solid debris, the two The passivation liquid at the position of end troweling roller 12 is kept clean to ensure the actual passivation ...

Abstract

The invention belongs to the technical field of machining, particularly relates to a shell plane weld joint passivation device for machining. Specific to the problem of the poor passivation effect ona metal shell plane weld joint in the prior art, the following scheme is now put forwards. According to the following scheme, the shell plane weld joint passivation device for machining comprises a passivation part; a passivation cavity is formed in the bottom of the passivation part; a liquid inlet pipe and a liquid outlet pipe are connected to the top of the passivation part; connecting parts are fixed to the two sides of the outer wall of the top of the passivation part; movable guide rails are connected to the top ends of the connecting parts; lifting frames are connected to the two ends of each movable guide rail; and fixing blocks are fixed to the four corners of the bottom of the passivation part. According to the shell plane weld joint passivation device for machining, the overallmovement of the passivation part is matched with the circulation of internal passivation liquid, so that the chips generated by passivation are prevented from always staying at a certain position to influence the actual passivation effect, and trowelling rollers at the two ends are used for trowelling the positions of weld joints which just enter and are to be discharged so as to improve the actual passivation effect on the weld joints.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a passivation device for shell plane welds used in mechanical processing. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. With the continuous development of mechanical technology, it has been applied to daily In all aspects of life and production and processing, anti-rust treatment is often required in the process of machining metal shells. [0003] Passivation treatment is a kind of anti-rust treatment for the plane of the shell. Passivation is to use the oxidation-reduction reaction between the oxidizing substance in the passivation solution and the metal to promote the formation of a layer of metal oxide on the metal surface to transform the metal surfac...
