Technical Field

The utility model relates to a collecting device for rolling by a planetary rolling mill, which is mainly used for collecting coils and conveying the coils by a process in the process of drawing copper and aluminum tube coils, and belongs to special supporting equipment of a metal coil drawing machine.

Background

The planetary rolling mill is a metal pipe inclined tube mill with a known technology, and is greatly popularized in the copper pipe industry due to advanced technology, and almost 100% of copper pipes for air conditioning and refrigeration in China are produced by the planetary rolling mill. In the last 20 years, with the gradual improvement of the technology, the yield and quality of the copper tube rolled by the planetary rolling mill are also greatly improved. In terms of yield, the initial annual yield of the planetary rolling mill is only 5000-6000 tons, and by the time about 30000 tons of annual yield is reached, the annual yield is changed to 5/ton/hr in consideration of factors such as actual working days.

The existing novel rolling mill generally adopts a continuous rolling mode to improve the yield, such as Chinese patent publication No. CN206535866U, and describes the continuous rolling mode. CN206535866U discloses a four-station gantry receiving rack, which comprises a gantry, a driving mechanism and a winding mechanism; the driving mechanism is fixedly arranged on the portal frame, and the winding mechanism is connected with the driving mechanism in a shaft way and is arranged in the middle of the portal frame; the driving mechanism comprises four motor speed reducers, and the driving mechanism is arranged on two sides of the portal frame in a pairwise aligned manner; the winding mechanism comprises four material receiving rollers, and each material receiving roller corresponds to a motor speed reducer. The four-station gantry material receiving frame can realize continuous rolling of the rolling mill, so that rolling efficiency is improved, and meanwhile, the service life of the rolling mill can be prolonged. Because four stations are in a parallel structure, the two stations are distributed on two bases, namely, each base is provided with only two stations, the occupied area is large, and the structure is complex.

The efficiency of the winding plays a very important role in the yield of the rolling mill. And the rolled pipe is pre-bent by a pre-bending machine and enters an upper rolling first station, a finished cylinder is hung on the upper rolling first station, and before the next rolled pipe reaches the upper rolling, the copper pipe at the first station is moved to a second station, the first station is vacated, and the next copper pipe is accepted. In the prior art, in actual production, only two stations are used for winding. When the copper tube at the first station is moved to the second station, the second station must complete unreeling. If the follow-up equipment has problems in actual production and can not be unreeled in time, the first station must stop winding, so that the efficiency is affected. As disclosed in chinese patent publication No. CN211464283U, the apparatus includes a gantry, a winding driving mechanism and a winding mechanism disposed on the gantry, the winding driving mechanism includes two winding motors disposed on two sides of the gantry, the winding mechanism has two material receiving rollers, each winding roller corresponds to one winding motor, and the winding roller is connected with a winding motor shaft corresponding thereto, each material receiving roller corresponds to a middle region of the gantry to form a winding station, a material moving frame, a trolley driving mechanism and a material moving trolley are further disposed on the gantry, the trolley driving mechanism is disposed on the material moving frame, and the material moving trolley is disposed on the material moving frame and is driven by the trolley driving mechanism to reciprocate between the two winding stations on the gantry. The device can stably and rapidly transfer the rolled pipe, and effectively prevent the rolled pipe from being mutually collided or scratched in the transfer process. It has only two receiving stations, no buffer station, and once any station has a problem, the rolling must stop working.
