Description

Technical Field

[0001] This utility model relates to the field of galvanized steel sheet straightening technology, specifically a continuous straightening device for processing high-adhesion galvanized steel sheets. Background Technology

[0002] The main purpose of tension straightening galvanized steel sheets is to eliminate internal stress and shape defects in the sheet through a combination of tension and bending, thereby obtaining a good sheet shape.

[0003] For example, the Chinese authorized patent with announcement number CN215965606U (A continuous straightening device for processing galvanized pipe profiled steel sheets) includes a worktable, on which a straightening mechanism and a collecting mechanism are provided; the straightening mechanism includes a C-shaped work frame, a rotating box one, a motor one, a rotating rod one, a block, four hydraulic cylinders, a rotating box two, a motor two, a rotating rod two, a rectangular block, and five extrusion mechanisms. The C-shaped work frame is fixedly installed on the top of the worktable, and the rotating box one is fixedly installed on the top of the worktable. The technical problem solved by this utility model is to provide a continuous straightening device for processing galvanized pipe profiled steel sheets that can adjust the distance between the upper roller group and the lower roller group according to the thickness of the steel sheet and the required flatness, and can spray cooling oil to cool and lubricate the rotating parts after long-term operation.

[0004] However, existing methods for straightening high-adhesion galvanized steel sheets mostly involve a single bending and straightening operation, resulting in poor straightening performance. Multiple straightening operations require a large floor space, leading to significant resource waste. Furthermore, the loading and unloading rollers require separation rollers and a rotating shaft for connection, which is time-consuming and labor-intensive to install and disassemble. Therefore, these methods do not meet current requirements. To address this, we propose a continuous straightening device for processing high-adhesion galvanized steel sheets. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous tension straightening device for processing high-adhesion galvanized steel sheets, so as to solve the problems mentioned in the background art. In the existing high-adhesion galvanized steel sheet tension straightening, most of them are straightened by a single bending and straightening operation, resulting in poor tension straightening effect. If multiple tension straightening operations are required, a large area is needed, resulting in serious waste of resources. In addition, the loading and unloading rollers need to be connected to the separation roller and the rotating shaft, which is time-consuming and labor-intensive to install and disassemble.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous straightening device for processing high-adhesion galvanized steel sheets, comprising: a first bending component, a feeding component disposed on one side of the first bending component, a straightening component disposed on the other side of the first bending component, a second bending component disposed on one side of the straightening component, the straightening component comprising a first guide roller, a first pressure roller disposed above the first guide roller, a second pressure roller disposed below the first guide roller, and a second guide roller disposed at the lower end of the second pressure roller.

[0007] Preferably, the straightening assembly further includes a stabilizing side plate located on both sides of the second guide roller. The side surface of the stabilizing side plate is provided with an adjustment groove, and the roller shafts at both ends of the first and second pressure rollers move up and down along the adjustment groove. A fixing knob is provided on one side of the roller shafts at both ends of the first and second pressure rollers.

[0008] Preferably, the feeding assembly includes a feeding roller and a support frame. One end of the support frame is provided with a rotating groove, and one side of the rotating groove is provided with a mounting plate. There are two mounting plates and two support frames. The mounting plate is rotatably connected to the rotating groove through a plate shaft integrally formed on the side surface.

[0009] Preferably, both ends of the feeding roller are provided with connecting plates, one side of the mounting plate is provided with a connecting slot, and the connecting plate is inserted into the connecting slot. One side of the connecting plate is provided with an installation knob, and one end of the installation knob passes through the mounting plate and the connecting plate and is threadedly fixed.

[0010] Preferably, a safety groove is provided on one side surface of the support frame near the rotating groove, and the mounting knob can pass through the safety groove.

[0011] Preferably, a discharge guide plate is provided on one side of the stabilizing side plate, and the discharge guide plate is welded and fixed to the stabilizing side plate.

[0012] Preferably, both the first bending assembly and the second bending assembly include bending rollers and roller frames, and multiple bending rollers are provided. The side surfaces of the roller frames and the stabilizing side plates are provided with connecting grooves, and both ends of the roller frames, the first guide roller, and the second guide roller are inserted into the connecting grooves through roller shafts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model consists of a straightening assembly composed of a first guide roller, a first lower pressure roller, a second lower pressure roller, a second guide roller, and a stabilizing side plate. After bending by the first bending assembly, the high-adhesion galvanized steel sheet is stretched and straightened by the pressure of the first guide roller and the first lower pressure roller. After bending by the second bending assembly, the high-adhesion galvanized steel sheet is stretched and straightened by the pressure of the second lower pressure roller and the second guide roller. This realizes continuous, multi-segment straightening, and it is a stacked form rather than a horizontal installation form, which reduces the horizontal footprint and improves resource utilization. Furthermore, the roller shafts at both ends of the first and second lower pressure rollers move up and down along the adjustment groove and are fixed by a fixing knob. This is suitable for high-adhesion galvanized steel sheets of different thicknesses, improving applicability. This solves the problem that in the past, when straightening high-adhesion galvanized steel sheets, most straightening operations were carried out by a single bending and straightening, resulting in poor straightening effect. If multiple straightening operations were required, a large footprint would be needed, resulting in serious resource waste.

[0015] (2) By inserting the connecting plate into the connecting slot and fixing it with the installation knob, the connection limit effect is achieved. When rotating, the feeding roller and the mounting plate can rotate together and will not separate and fall off. When rotating, the installation knob can pass through the safety groove without hindering normal use. When disassembling the feeding roller to change materials, only the installation knob needs to be removed to replace the feeding roller. Compared with the existing feeding roller and mounting plate being a whole for feeding, it is not necessary to disassemble the mounting plate, and therefore it is not necessary to disassemble the connection structure with the support frame. It is quick and convenient, improves flexibility, and solves the problem that the existing feeding rollers need to separate the roller and the shaft connection when feeding, and the installation and disassembly are time-consuming and laborious.

[0023] When connecting the feed roller 16 to the mounting plate 20, such as Figure 3 , Figure 4As shown, the connecting plate 17 is inserted into the connecting slot 21 to limit the connection. When rotating, the feeding roller 16 and the mounting plate 20 can rotate together. One end of the mounting knob 18 passes through the mounting plate 20 and the connecting plate 17 and is threaded to fix the feeding roller 16 and the mounting plate 20, so that they will not separate and fall off when rotating. A safety groove 22 is provided on one side surface of the support frame 19 near the rotating groove 23. When rotating, the mounting knob 18 can pass through the safety groove 22 without affecting normal use. When disassembling the feeding roller 16 for material replacement, only the mounting knob 18 needs to be removed to replace the feeding roller 16.

It is quick and convenient and improves flexibility.

[0024] For further information, please refer to Figure 1 , 2 A discharge guide plate 5 is provided on one side of the stabilizing side plate 15, and the discharge guide plate 5 is welded and fixed to the stabilizing side plate 15. The first bending assembly 1 and the second bending assembly 4 both include bending rollers 12 and roller frames 13, and multiple bending rollers 12 are provided. The roller frames 13 and the side surfaces of the stabilizing side plate 15 are provided with connecting grooves 14, and both ends of the roller frames 13, the first guide roller 6 and the second guide roller 8 are inserted into the connecting grooves 14 through roller shafts. When straightening high-adhesion galvanized steel sheets, one end of the high-adhesion galvanized steel sheet moves upward along the bending roller 12 of the first bending assembly 1, and then passes through the first guide roller 6 and the first guide roller 8. The lower pressure roller 7 stretches and straightens the high-adhesion galvanized steel sheet, which then moves downward through the bending roller 12 of the second bending component 4. After being stretched and straightened by the second guide roller 8 and the second lower pressure roller 9, the sheet is discharged along the discharge guide plate 5 after the straightening is completed. This achieves continuous, multi-segment straightening, and it is a stacked form rather than a horizontal installation, which reduces the horizontal footprint and improves resource utilization. Furthermore, the roller shafts at both ends of the first lower pressure roller 7 and the second lower pressure roller 9 move up and down along the adjusting groove 10 and are fixed by the fixing knob 11. This method is suitable for high-adhesion galvanized steel sheets of different thicknesses, thus improving applicability.
