Description

Automatic pickling system for copper pipe

Technical Field

The invention relates to a system for automatically operating copper pipe pickling operation.

Background

Copper tubing is a commonly used tubing; in the copper pipe production process, the length of the copper pipe can be 40 meters generally after material breakage, and the whole copper pipe is required to be subjected to acid washing treatment.

Copper pipes, including many wires, pipes and profiles, need to be subjected to cleaning operations such as acid washing, alkali washing and the like in the production process; because these products are generally long (the section bar is at least 6 meters long), they need to be placed on special hanging frames first during cleaning and then hung in a cleaning tank for treatment, such as a tunnel type closed pipe with the Chinese patent publication No. CN204918784U, a section bar pickling system, a hanging frame for pipeline pickling and phosphating with the Chinese patent publication No. CN209428614U, and the like.

On one hand, the existing hanging bracket has simpler function and needs manual operation; on the other hand, the production process is mostly dependent on manual operation, so that the operation efficiency is low, and the utilization rate of cleaning tanks such as a pickling tank is low.

Therefore, it is necessary to design an automated system for such cleaning operations to improve the productivity.

Fig. 18 (d), the lifting mechanism 3 works reversely to drive the copper pipe hanger 4 to lift, and during the lifting process, even if the supporting arm 422 carries the copper pipe away from the original copper pipe bracket;

when the copper pipe hanger 4 is lifted to a sufficient height, the lifting drive 32 can stop working, then the travelling mechanism 31 acts to transfer the copper pipe to the next station for discharging, and the discharging process is the reverse operation process of fig. 18.

In the process of lifting and transferring, the compression bar 441 is tightly attached to the upper surface of the copper pipe under the action of gravity and the downward elasticity of the spring 445, i.e. the copper pipe is reliably pressed on the upper surface of the supporting arm 422, thereby avoiding the displacement of the copper pipe in the process of transferring.

Further, in the process of fig. 18 (d), if the copper pipe is located at the station of the pickling tank 11, i.e. the copper pipe is taken out of the pickling tank 11, at this time, referring to fig. 19, after the copper pipe leaves the surface of the pickling solution, the 2 lifting mechanisms 3 of the copper pipe lifting device are controlled so that the heights of the two sides of the copper pipe lifting device 4 are not uniform, even if the supporting frame 41 is inclined by a certain angle along with the whole copper pipe, so that the pickling solution can flow out from the copper pipe holes, the discharge of the pickling solution is accelerated, and the copper pipe is kept in the pickling tank 11.

Or when the copper pipe lifting device is lifted above the draining pool, referring to fig. 19, the 2 lifting mechanisms 3 of the copper pipe lifting device are controlled to enable the heights of two sides of the copper pipe lifting device 4 to be inconsistent, even if the supporting frame 41 is inclined at a certain angle along with the whole copper pipe, so that pickling solution can flow out of copper pipe holes, and the pickling solution is discharged into the draining pool.
