Continuous rolling planetary mill

Abstract

The invention relates to a continuous rolling planetary rolling mill. A first feeding mechanism, a second feeding mechanism and a rolling mechanism are sequentially arranged from one side to the other side according to the sequence of stations. The first feeding mechanism pushes a received to-be-rolled material to the second feeding mechanism, returns to the initial station after pushing the materials and continues to receive the next to-be-rolled material. The second feeding mechanism pushes the material received from the first feeding mechanism to the rolling mechanism, returns to the initial station after pushing the material and continues to receive the next to-be-rolled material pushed by the first feeding mechanism. The overturning time of ingots, time for pushing and returning of a feeding trolley, and time for a core bar to penetrate through the ingots and return are shortened, feeding continuity and rolling continuity of the materials are achieved, rolling efficiency is greatly improved, impact to the rolling mechanism is reduced, and the service life of the rolling mill is prolonged.

Description

technical field [0001] The invention relates to the field of metallurgical rolling, in particular to a continuous rolling planetary rolling mill. Background technique [0002] Existing planetary rolling mills generally include a feeding mechanism for conveying hollow slabs and a planetary host for casting hollow slabs. The feeding mechanism consists of a conveying platform and a propulsion mechanism arranged on the top of the conveying platform and used to push forward the hollow cast slab. The propulsion mechanism is composed of a core rod with a core rod, a push head for pushing the core rod forward, and a push trolley for pushing the hollow cast slab forward. Then, in the working process of the existing planetary rolling mill, the pusher will send the mandrel with the mandrel into the hollow casting slab and withstand the hollow casting slab, and send it to the roll group of the planetary main machine together, and wait for the planetary main machine to roll. , Rolled p...

Problems solved by technology

Therefore, in this working process, when the hollow cast slab is loaded, it is necessary to pass through the cast slab through the core rod, and then push the hollow cast slab into the planetary host for rolling through the push trolley. After the rolling is completed, the push trolley can Drive the mandrel to withdraw from the slab to realize the turning and winding of the slab. In this way, the push trolley cannot return to continue loading the next hollow slab during the period from the start of slab loading to the completion of slab rolling. This will inevitably cause the discontinuity of feeding, rolling, and receiving, that is, the planetary main machine is in an idle state during the process of returning the pushing trolley and conveying the slab, and the rolling process of the planetary main machine There is no material loading to undertake in

[0003] Therefore, due to the above-mentioned structure of the existing planetary rolling mill, not only the rolling efficiency is low, but also because of the intermittent rolling of the planetary main machine, it is easy to bring a certain impact to the planetary main machine, which affects the service life of the planetary rolling mill
