Abstract

The utility model discloses a straightening element for gripping-bending machine comprising a bracket, two groups of upper and lower back-up rolls, two groups of upper and lower intermediate rolls, two groups of upper and lower working rolls, wherein two ends of the two groups of upper and lower back-up rolls, the two groups of upper and lower intermediate rolls and the two groups of upper and lower working rolls are respectively and actively connected with the bracket. The utility model is characterized in that, a clearance for copper strips to pass through is arranged between the two groups of upper and lower working rolls, two ends of every back-up roll of the two groups of upper and lower back-up rolls are provided with bearing seats, which are arranged inside the bracket and provided with needle roller bearings, wherein the needle roller bearings are arranged on the back-up rolls, one side of every needle roller bearing closed to the middle portion of every back-up roll is respectively provided with a bearing touched with the needle roller bearing. The utility model employs such a structure thereby improving the service life of the bearings on the two ends of the back-up rolls, the yield of strips and the productivity.

Description

Stretch bending-straightening machine aligning unit

Technical field

The utility model relates to stretch bending-straightening machine, especially relates to stretch bending-straightening machine aligning unit.

Background technology

As Fig. 2, shown in Figure 3, existing stretch bending-straightening machine aligning unit comprises two groups of backing rolls 5 up and down, two groups of intermediate calender rolls 8 up and down, two groups of working rolls 10 up and down, frame 2, two groups of backing rolls 5 up and down, two groups of intermediate calender rolls 8 up and down, the two ends of two groups of working rolls 10 and frame 2 flexibly connect up and down, has the gap that band 9 passes between two groups of working rolls 10 up and down, the two ends of backing roll 5 all have the bearing block 4 that is positioned at frame 2 about in the of every, needle bearing 3 is installed in the bearing block 4, needle bearing 3 is installed on the backing roll 5, the end of backing roll 5 has the plane bearing that is positioned at end cap 61 that contacts with needle bearing 3, such structure is because plane bearing 1 is positioned at the end of backing roll 5, plane bearing 1 internal diameter is less, plane bearing 1 is fragile, cause backing roll 5 after the damage of bearings again, intermediate calender rolls 8, working roll 10 chews mutually, thereby it is frequent to cause plane bearing 1 to be changed, backing roll 5, intermediate calender rolls 8, working roll 10 is also changed frequently, and not only the yield rate of band 9 is lower, and production capacity also is restricted.

The utility model content

Technical problem to be solved in the utility model is: is provided a kind of service life that prolongs bearing, backing roll, intermediate calender rolls, working roll, reduces and change frequency, thereby the stretch bending-straightening machine that improves production capacity and band yield rate is aligned the unit.

Solve this technical problem, the technical solution of the utility model is: a section stretch bending-straightening machine aligning unit, comprise frame, on, following two groups of backing rolls, on, following two groups of intermediate calender rolls, on, following two groups of working rolls, on described, following two groups of backing rolls, on, following two groups of intermediate calender rolls, on, the two ends of two groups of working rolls all flexibly connect with frame respectively down, on described, has the gap that copper strips passes between following two groups of working rolls, on described, the two ends of every backing roll of two groups of backing rolls all have the bearing block that is positioned at frame down, needle bearing is installed in the bearing block, needle bearing is installed on the backing roll, and a side at the close backing roll middle part of described needle bearing is provided with and the contacted bearing of needle bearing.

One side at the close backing roll middle part of described needle bearing be provided with the contacted bearing of needle bearing be plane bearing.

The diameter of described plane bearing is 8 millimeters.

Side away from the backing roll middle part of described needle bearing is provided with enclosing cover.

The utility model is owing to adopt such structure, compared with prior art, changed the position of the bearing at two groups of backing roll two ends up and down, bearing is adjusted to a side at the close backing roll middle part of needle bearing from the side away from the backing roll middle part of needle bearing, because backing roll is the step axle, the internal diameter of bearing increases, the bearing load of bearing increases, improved the service life of bearing, avoided causing backing roll after original damage of bearings, intermediate calender rolls, chewing mutually of working roll, reduced bearing, backing roll, intermediate calender rolls, the time of the replacing of working roll and workload, backing roll, intermediate calender rolls, the smooth operation of working roll has improved the yield rate of band, and production capacity also is improved simultaneously.
