[0002] At present, in the hot-rolling mills for copper and copper alloy plates and strips, the rack roller tables arranged inside the columns of the two racks are made into a group of 3 roller tables driven by a motor. Due to the limited space inside the frame, the shape structure and strength of the bearing seat are limited to a large extent. Therefore, during the reciprocating rolling process of the ingot, once the end of the billet directly hits the roller table of the frame, it will cause the frame Damage to the roller table and shutdown accidents will affect the productivity of the rolling mill and waste the energy for heating up the ingot

Embodiment Construction
[0013] Such as figure 1 and figure 2 As shown, it is an embodiment of the rack roller table assembly of the present invention. The two ends of the rack roller table 1 pass through the roller table mounting holes 7 of the rack column 6 and extend to the outside of the frame column, and the outer sides of the frame column are fixed with bearing seats. Frame 4, bearing seat 2 is installed in the bearing seat frame, bearing 3 is installed in the bearing seat, both ends of the roller table of the frame are installed in the bearing, an elastic expansion device is arranged between the lower part of the bearing seat and the bearing seat frame, and the roller table The height of the mounting hole is greater than the diameter of the frame roller table in the roller table mounting hole to provide an elastic space for the frame roller table to jump up and down. The elastic telescopic device includes a spring 5 arranged vertically, the lower end of the spring is arranged in the spring gr...

The invention discloses a frame roller table assembly. The two ends of the frame roller table pass through the roller table installation holes of the frame column and extend to the outside of the frame column. A bearing seat frame is fixed on the outside of the frame column, and bearings are installed in the bearing seat frame. The bearing seat is installed in the bearing seat, and the two ends of the roller table of the frame are installed in the bearing. An elastic expansion device is installed between the lower part of the bearing seat and the frame of the bearing seat. The diameter of the rack roller table is adjusted to provide the elastic space for the rack roller table to jump up and down. Since the bearing seat of the rack roller table is arranged on the outside or front and rear of the frame without space restrictions, and can slide up and down in the vertical direction in the spring-supported bearing seat frame, the impact-resistant high-strength elastic rack roller table is formed , Such a single roller table structure is extremely convenient for maintenance and disassembly.
Description
technical field [0001] The invention relates to the field of hot rolling mills for copper and copper alloy plates and strips. Background technique [0002] At present, in the hot-rolling mills for copper and copper alloy plates and strips, the rack roller tables arranged inside the columns of the two racks are made into a group of 3 roller tables driven by a motor. Due to the limited space inside the frame, the shape structure and strength of the bearing seat are limited to a large extent. Therefore, during the reciprocating rolling process of the ingot, once the end of the billet directly hits the roller table of the frame, it will cause the frame The damage of the roller table and the occurrence of downtime accidents will affect the productivity of the rolling mill and waste the heating energy of the ingot. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rack roller assembly with simple structure, impact res...
