Description

Technical Field

[0002] Galvanized steel strip is a cold-rolled or hot-rolled, long and narrow steel strip plate coated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel strip substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the strip substrate, so it has strong corrosion resistance.

[0003] Post-treatment of galvanized steel strip includes three aspects: passivation, prephosphating and oiling. First of all, the galvanized steel strip should be passivated, which can improve the surface structure and gloss of the galvanized layer, improve the corrosion resistance and service life of the galvanized layer, and improve the bonding between the coating and the base metal. The passivation treatment mainly adopts chromate passivation. Some activators such as fluoride, phosphoric acid or sulfuric acid are added to the passivation solution to obtain a thicker chromate film after passivation. When there is fluoride in the passivation solution, the surface tension of the steel strip can be reduced, the film-forming reaction can be accelerated, and the chemical polishing effect can be increased to make the passivation film delicate and bright.

[0004] In the prior art, a lot of bent steel strips are produced during construction, which need to be corrected so as to be reused. In view of this, a hot-dip galvanized steel strip straightening device is developed. Utility Model Content

[0027] A table top 1, a side wall of the table top 1 is provided with an extension frame 2;

[0028] A clamping assembly 3, wherein the clamping assembly 3 is arranged on the upper end surface of the table 1;

[0029] A correction component 4, which is arranged on the top of the platform 1;

[0030] The clamping assembly 3 includes a gantry frame 3-1, which is arranged on the upper end surface of the table plate 1, a connecting frame 3-2 is arranged on one side surface of the gantry frame 3-1, a fixed frame 3-3 is arranged on the side wall of the connecting frame 3-2, a force-bearing wheel 3-4 is arranged in the fixed frame 3-3, a telescopic frame 3-5 is arranged on the other side wall of the gantry frame 3-1, a movable frame 3-6 is arranged at the end of the telescopic frame 3-5, and an extrusion wheel 3-7 is arranged inside the movable frame 3-6.

[0031] In this embodiment, the force wheel 3-4 installed on the connecting frame 3-2 in the clamping assembly 3 contacts one side of the steel strip, and the other side of the steel strip pushes the movable frame 3-6 to move through the telescopic frame 3-5, so that the extrusion wheel 3-7 is clamped on the other side of the steel strip. During the movement of the steel strip, the force wheel 3-4 moves in a state of being clamped by the extrusion wheel 3-7, and at this time, the force wheel 3-4 and the extrusion wheel 3-7 rotate in opposite directions.

[0032] Specifically, the force wheel 3-4 is connected to the inside of the fixed frame 3-3 through a bearing, and the extrusion wheel 3-7 is connected to the movable frame 3-6 through a bearing. The fixed frame 3-3 and the movable frame 3-6 are both C-shaped structures.

[0033] In this embodiment, a bearing connection is adopted to enable the extrusion wheel 3-7 and the force-bearing wheel 3-4 to rotate.

[0034] Furthermore, the correction component 4 includes a force-bearing plate 4-1, which is arranged on the upper end surface of the table 1, and a correction groove 4-2 is arranged on the inner side wall of the force-bearing plate 4-1, and a pushing cylinder 4-3 is arranged on the extension frame 2, and the telescopic end of the pushing cylinder 4-3 is connected to a pushing plate 4-4, and the position of the pushing plate 4-4 corresponds to that of the force-bearing plate 4-1, and an extrusion groove 4-5 is opened on the pushing plate 4-4, and a sliding track 4-6 is opened on the upper end surface of the table 1, and a limiting frame 4-7 is arranged on the back of the pushing plate 4-4, and the bottom of the limiting frame 4-7 is embedded in the sliding track 4-6.

[0035] In this embodiment, after the force plate 4-1 is fixed on the table 1, the pushing cylinder 4-3 drives the pushing plate 4-4 to move, and the pushing plate 4-4 slides in the sliding track 4-6 by the limiting frame 4-7, so that the pushing plate 4-4 moves more smoothly, and the strip steel moves between the correction groove 4-2 and the extrusion groove 4-5 and is extruded, so that the bent part of the strip steel achieves the effect of correction.

[0036] Furthermore, the correction groove 4-2 and the extrusion groove 4-5 are spliced ​​to form a rectangular structure.

[0037] Furthermore, the telescopic frame 3-5 is composed of a movable tube 3-501, a pushing spring 3-502, and a pushing rod 3-503.

[0041] When the strip needs to be corrected, the force wheel 3-4 placed on the receiving frame contacts one side of the strip, and the other side of the strip is pushed by the telescopic frame 3-5 to move the movable frame 3-6, so that the extrusion wheel 3-7 is clamped on the other side of the strip. During the movement of the strip, the force wheel 3-4 and the extrusion wheel 3-7 are clamped to move. At this time, the force wheel 3-4 and the extrusion wheel 3-7 are connected by bearings to realize self-rotation in the opposite direction. After the force plate 4-1 is fixed on the table 1, The pushing cylinder 4-3 drives the pushing plate 4-4 to move, and the pushing plate 4-4 slides in the sliding track 4-6 by the limiting frame 4-7, so that the pushing plate 4-4 moves more smoothly, and the strip steel moves between the correction groove 4-2 and the extrusion groove 4-5 for extrusion, so that the bent part of the strip steel achieves the effect of correction, and the pushing spring 3-502 drives the pushing rod 3-503 to move to the outside of the movable tube 3-501, so that the pushing rod 3-503 drives the extrusion wheel 3-7 to extrude the strip steel.
