Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to an aluminum profile straightening device. Background Art

[0002] Aluminum products are made of aluminum and other alloy elements. They are usually processed into castings, forgings, foils, plates, strips, tubes and bar profiles, and then processed by cold bending, sawing, drilling, assembly and coloring. During the processing of aluminum, it is easy to bend and deform. Generally, aluminum profile straightening devices are needed for straightening. Existing straightening devices are mainly divided into two types: stretch straightening and roller straightening.

[0003] At present, roller straightening is to use two sets of symmetrical rotating rollers to roll the deformed aluminum profile to achieve the straightening effect. However, in order to ensure the rolling effect, the distance between the two sets of rotating rollers is the same as the outer size of the aluminum profile. Therefore, before the aluminum profile enters the two sets of rotating rollers for transmission and movement, the aluminum profile cannot be automatically introduced between the two sets of rotating rollers. At this time, the user needs to manually push the aluminum profile to move so that it can be inserted between the two sets of rotating rollers. The operation is troublesome, time-consuming and labor-intensive.

[0004] Therefore, we propose an aluminum profile straightening device to solve the above problems. Utility Model Content

The upper pressure roller 2 is not set on the roller 1. One end of the aluminum profile is placed on the L-shaped support plate 8, and the other end is placed on the lower roller 1. When the reciprocating screw 6 rotates, the slider 7 moves along the length direction of the reciprocating screw 6, thereby driving the L-shaped support plate 8 to support the aluminum profile close to the gap between the lower roller 1 and the upper pressure roller 2. When the lower roller 1 and the upper pressure roller 2 rotate, the aluminum profile can be driven to move and be rolled and straightened at the same time. When the slider 7 moves to the closest to the lower roller 1, it can move back away from the lower roller 1, so that when the aluminum profile passes through between the lower roller 1 and the upper pressure roller 2, the slider 7 can drive the L-shaped support plate 8 to restore to its original state.

[0026] See also Figure 1-2 In order to facilitate the driving of the reciprocating screw 6 and the lower roller 1 to rotate, a transmission structure is set between the reciprocating screw 6 and the lower roller 1 for linkage.

At this time, when the motor 15 is working, it can not only drive the lower roller 1 to rotate, but also drive the reciprocating screw 6 to rotate.
