Description
Technical Field
The utility model relates to a roll-in, roll bending forming technology, concretely relates to a roller set for roll bending takes shape.
Background
Roll bending is a process of continuously bending a metal strip such as a coil or a strip transversely by a plurality of sequentially arranged forming rolls (see fig. 3) to form a profile having a specific cross section. The forming rollers rotate, and the linear speeds of the rollers in each group are different, so that the following two defects can occur during roll bending:
1) in FIG. 3, the material at A is not constrained, so that the instability phenomenon occurs and wrinkles are easy to occur; 2)
in the roll bending forming process, the edges of the plate strips are wrinkled and wavy, so that the appearance quality of parts is seriously influenced. Therefore, improvements and enhancements to the roll-forming process are highly desirable.
Disclosure of Invention
In order to solve the above problem, the utility model provides a roller set for roll bending takes shape.
The utility model adopts the technical proposal that: a roller set for roll bending forming comprises an upper roller and a lower roller, wherein the upper roller comprises an upper roller and an upper roller sleeve sleeved on the upper roller; a convex ring is processed on the upper roller sleeve;
the lower roller comprises a lower roller wheel and a lower roller sleeve sleeved on the lower roller wheel; and an annular groove corresponding to the convex ring is processed on the lower roller sleeve.
Preferably, the upper roller is axially provided with a first shaft hole for mounting a first transmission shaft;
and a second shaft hole is axially formed in the lower roller and used for mounting a second transmission shaft.
Preferably, the first transmission shaft and the second transmission shaft are mounted on the fixing base through bearings.
Preferably, a fixing plate is arranged between the fixing seat and the upper roller wheel and between the fixing seat and the lower roller wheel.
Preferably, the outer diameter of the male ring is larger than the outer diameter of the annular groove.
Preferably, the outer diameter of the male ring is one third greater than the outer diameter of the annular groove.
Preferably, the width of the annular groove is greater than the width of the torus.
Compared with the prior art, the beneficial effects of the utility model are that: the roller group solves the defect that the multi-group roller combination roll bending process is easy to cause wrinkles and the edges are easy to wrinkle and form waves. The surface of the material after roll bending is smooth and has no wrinkles, the appearance quality is good, and the device is simple and saves materials, thereby saving the cost.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Refer to fig. 1 and 2;
the roller set is improved on the basis of the original roller set, three groups of rollers are omitted from the original four-group roller combined roll bending forming device, and only one group of rollers is reserved to finish roll bending forming; the device comprises an upper roller 2 and a lower roller 4, wherein the upper roller 2 comprises an upper roller 210 and an upper roller sleeve 220 sleeved on the upper roller 210, and the upper roller 210 is axially provided with a first shaft hole 240 for mounting a first transmission shaft 5; a convex ring 230 is processed on the upper roller sleeve 220;
the lower roller 4 comprises a lower roller wheel 410 and a lower roller sleeve 420 sleeved on the lower roller wheel 410, and the lower roller wheel 410 is axially provided with a second shaft hole 440 for mounting the second transmission shaft 6; the lower roll sleeve 420 is provided with an annular groove 430 corresponding to the convex ring 230; and the width of the annular groove 430 is greater than the width of the torus 230;
the first transmission shaft 5 and the second transmission shaft 6 are installed on the fixed seat.
Further, a fixing plate 7 is arranged between the fixing seat 1 and the upper roller 210 and the lower roller 410, and the fixing plate 7 is used for adjusting the position of the lower roller.
Further, the outer diameter of the protruding ring 230 is larger than the outer diameter of the annular groove 430, and in this case, the outer diameter of the protruding ring 230 is one third larger than the outer diameter of the annular groove 430.
As shown in figure 2, the roller group of the application only adopts the upper roller 2 with a big upper part and a small lower roller 4 to combine to complete the roller bending forming device, wherein the lower roller 4 is movable and is used for adjusting the position, thereby achieving the purpose of adjusting the radius of the circular arc and meeting various parameters of the circular arc.
