Abstract
Description
Technical Field
[0001] This utility model belongs to the field of strip straightening technology, specifically relating to a galvanized strip straightening device. Background Technology
[0002] During the rolling process, strip steel will produce plate shape defects such as waves, wavy lines, and sickle bends. The effective means to eliminate these plate shape defects is tension straightening. At present, the continuous roller tension straightening used for strip steel tension straightening is only widely used for cold-rolled strip steel with a thickness of less than 3mm due to the limitations of tension straightening force and structure. For hot-rolled strip steel with a larger thickness, these plate shape defects are mainly eliminated by leveling and roller straightening, which has the disadvantages of high cost and poor effect.
[0003] Existing strip straightening devices mostly have fixed straightening groove widths and can only straighten strips of corresponding sizes. When moving and straightening strips of different widths, problems such as strip displacement and misalignment can easily occur, affecting the overall straightening effect of the strips. Therefore, a galvanized strip straightening device is needed to help solve this problem. Utility Model Content

Two sets of threads with opposite helical directions are symmetrically provided on the bidirectional lead screw 10. The bidirectional lead screw 10 and the protrusion are threadedly engaged. An adjustment motor 9 for rotating the bidirectional lead screw 10 is installed on the outer side of the receiving frame 4.
[0028] By cooperating with the guide plate 5 and the adjustment component 8 set inside the receiving frame 4, the adjustment motor 9 can be started during operation. The adjustment motor 9 drives the bidirectional lead screw 10 to rotate as a whole. The bidirectional lead screw 10 is threadedly engaged with the protrusion, thereby moving the guide plate 5. During the movement of the guide plate 5, the two guide plates 5 are moved to the designated position, thus adapting to the receiving requirements of strip steel of different widths. When the strip steel is moved and straightened, the strip steel offset and misalignment can be avoided as much as possible, thus improving the overall practicality of the device.

[0034] The strip steel is placed at the top of the receiving frame 4 by the clamping component 12. The electric push rod 15 is activated. When the electric push rod 15 moves, it drives the clamping plate 14 to move as a whole. The clamping plate 14 presses against the top of the strip steel. As the strip steel moves, it is assisted in straightening. After straightening, it is convenient to perform auxiliary processing on the strip steel. It can meet the straightening needs of strip steel of different thicknesses and improve the overall practicality of the device.
[0035] Working principle:
[0036] Before the strip needs to be straightened, start the adjusting motor 9. The adjusting motor 9 drives the bidirectional lead screw 10 to rotate as a whole. The bidirectional lead screw 10 is threadedly engaged with the protrusion, thereby moving the guide plate 5. During the movement of the guide plate 5, the two guide plates 5 are moved to the designated position to meet the receiving requirements of strips of different widths. The position of the receiving frame 4 can be effectively determined by the scale plate 11 at the top of the receiving cavity 41.
[0037] During the straightening process, the strip is placed at the top of the receiving frame 4. The electric push rod 15 is started. When the electric push rod 15 moves, it drives the pressure plate 14 to move as a whole. The pressure plate 14 presses against the top of the strip. As the strip moves, it is used to assist in the straightening process. After straightening, it is convenient to perform auxiliary processing on the strip.
