[0001] The utility model relates to the technical field of straightening machines, in particular to an electric angle adjustment mechanism for a straightening machine. Background Art

[0002] Straightening machines are equipment for straightening metal profiles, bars, pipes, wires, etc. Straightening machines use straightening rollers to squeeze bars and other materials to change their straightness. Generally, there are two rows of straightening rollers, with varying numbers. There are also two-roller straightening machines, which rely on the angle change of two rollers (concave in the middle, hyperbolic rollers) to straighten materials of different diameters. The main types include pressure straightening machines, balanced roller straightening machines, shoe roller straightening machines, rotary reverse bending straightening machines, etc.

[0003] When the straightening machine is working, in order to achieve different straightening degrees for workpieces of different diameters, the angle of the straightening wheel needs to be adjusted in real time.

[0004] The existing method of adjusting the angle of the straightening wheel mainly relies on manpower using a wrench, specifically: using a wrench to rotate the angle adjustment nut, the angle adjustment nut causes the angle adjustment screw to move back and forth, and finally drives the angle adjustment ring to rotate. However, the structure connecting the straightening wheel is complicated, the connecting rod mechanism and the joint bearing in the structure have large resistance, and the adjustment parts have heavy weight and sliding friction. Adjustment is particularly laborious and time-consuming, and the labor intensity of the staff is high.

[0005] Therefore, there is an urgent need for an electric angle adjustment mechanism for a straightening machine, which is used to facilitate the adjustment of the angle of the straightening wheel and reduce the labor intensity of the staff. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] See attached Figure 1-7 , as shown, an electric angle adjustment mechanism of a straightening machine comprises a casing 1, the casing 1 is composed of four rigid plates 19 connected end to end, i.e., steel plates, an end plate 21 is provided at one end of the casing 1, and the end plate 21 is used to enhance the structural strength and stability of the entire casing 1, a mounting plate 2 is provided in the casing 1 and parallel to the end plate 21, a mounting circle is provided on the mounting plate 2, a core barrel 3 is sleeved in the mounting circle, six connecting holes 18 are symmetrically provided on both sides of the port of the core barrel 3, and the six connecting holes 18 are used to connect the straightening wheel, and the angle of the straightening wheel is changed by rotating the core barrel 3;

[0031] The front and rear ends of the core barrel 3 are respectively provided with a front retaining ring 5 and a rear retaining ring 6. The core barrel 3 is provided with an angle adjustment ring 4 between the front retaining ring 5 and the rear retaining ring 6. A key block 22 is provided on one side wall of the angle adjustment ring 4 close to the core barrel 3. At the same time, a key groove is provided at a position of the core barrel 3 corresponding to the key block 22. The key groove cooperates with the key block 22. When the angle adjustment ring 4 rotates, the core barrel 3 is driven to rotate through the key block 22.

[0032] A connecting ring 7 is sleeved on the front retaining ring 5 through bolts, and four connecting frames 17 are set between the connecting ring 7 and the rear retaining ring 6. The four connecting frames 17 are arranged in an X shape. The connecting frame 17 is connected to the casing 1 to limit the front retaining ring 5 and the rear retaining ring 6. A first worm wheel 11 is provided on one side of the angle adjustment ring 4. A worm 10 is matched on the first worm wheel 11. The worm 10 is installed in the worm 10 seat 8.
