Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling mills, in particular to a discharge mechanism for cold rolling mills. Background Art

[0002] Currently, cold-rolling tube mills utilize annular perforations to cold-roll rough tubes. These mills offer excellent billet production capabilities and can also produce standard precision seamless non-ferrous metal tubes. The most significant feature of cold-rolling tube mills is their high material utilization rate, while achieving superior precision and surface finish compared to cold-drawn tubes. While different operating modes and structures vary, cold-rolling tube mills primarily consist of the following components: a main motor and its transmission mechanism, a steering gear, a drive shaft, a rolling mill frame, a rotary feed mechanism, a feed chuck and bed, a mandrel clamping device, inlet and outlet chucks, a loading mechanism, and a discharge mechanism. After the formed steel tubes are discharged from the discharge mechanism, a discharge rack is typically installed behind the discharge mechanism to facilitate collection. This rack features a material channel directly opposite the discharge mechanism. The steel tubes discharged from the discharge mechanism are gradually fed into the channel. Once the formed steel tubes are fully loaded into the channel, workers remove them from the channel.

[0003] After searching, the existing Chinese patent announcement number is: CN221388140U, which provides a cold rolling mill unloading mechanism.
