Description

Technical Field

[0001] This utility model relates to the field of stainless steel coil processing technology, specifically a straightening device for stainless steel coil processing. Background Technology

[0002] Stainless steel coils are corrosion-resistant steel products. After uncoiling, stainless steel coils often have problems such as bending and wavy deformation, which need to be eliminated by straightening devices to eliminate internal stress.

[0003] Chinese Patent CN222036374U discloses a straightening device for processing stainless steel coils, including a base, a winding wheel, a first leveling roller A, a second leveling roller A, a first leveling roller B, and a second leveling roller B. Support plates are provided at both ends of the top of the base, and a stepper motor is installed at one end of one side of each support plate. A straightening assembly is provided between the support plates, including the winding wheel, the first leveling roller A, and the second leveling roller A. The winding wheel is located at one end between the support plates. The extrusion force generated between the second leveling roller A and the second leveling roller B, and between the first leveling roller A and the first leveling roller B, can be used to level the stainless steel coil, effectively eliminating slight bending or deformation on the surface of the stainless steel coil, restoring its flatness, and effectively achieving the straightening effect.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: after long-term use, the surfaces of multiple sets of leveling rollers will be scratched by direct friction with the stainless steel coil. If they are not replaced in time, they will damage the subsequent stainless steel coil and reduce the leveling quality. Furthermore, the above-mentioned straightening device is not convenient for quick disassembly and replacement of multiple sets of leveling rollers, which reduces processing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a straightening device for processing stainless steel coils.

[0006] The technical solution of this utility model is as follows: A straightening device for processing stainless steel coils includes a fixed base with a support at its bottom; a movable base that is slidably connected to the fixed base; a lower rotating mechanism disposed between the fixed base and the movable base, on which multiple sets of lower straightening rollers are detachably mounted; an upper rotating mechanism disposed between the fixed base and the movable base and distributed above the lower rotating mechanism, on which multiple sets of upper straightening rollers are detachably mounted, the upper straightening rollers having the same structure as the lower straightening rollers, and the upper rotating mechanism having the same structure as the lower rotating mechanism. The upper rotating mechanism consists of multiple sets of drive shafts rotatably connected to the fixed base via drive components and multiple sets of driven shafts rotatably connected to the movable base. The lower straightening rollers or upper straightening rollers are detachably mounted between the drive shafts and driven shafts; and a support mechanism consisting of multiple sets of abutment seats that are vertically and vertically connected to the fixed base, the abutment seats abutting against the bottom end of the outer circumferential surface of the lower straightening rollers or upper straightening rollers.

[0007] Preferably, the fixed seat is L-shaped, and a support seat is installed on the fixed seat. A threaded rod is threadedly connected to the support seat, and one end of the threaded rod is rotatably connected to the movable seat.

[0008] Preferably, slots are provided on both the drive shaft and the driven shaft, and insert rods are installed at the ends of the lower straightening roller or the upper straightening roller. The insert rods are inserted into the slots and are square rods.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, this utility model proposes a straightening device for processing stainless steel coils, including a fixed base 1, a movable base 101, a lower rotating mechanism, an upper rotating mechanism, and a support mechanism. A bracket 102 is provided at the bottom of the fixed base 1. The movable base 101 is slidably connected to the fixed base 1. A guide groove is provided on the fixed base 1, and a slider is provided at the bottom of the movable base 101, which slidably connects to the guide groove, improving the stability of the sliding connection between the movable base 101 and the fixed base 1. The lower rotating mechanism is located between the fixed base 1 and the movable base 101, and multiple sets of lower straightening rollers 3 are detachably mounted on the lower rotating mechanism. The upper rotating mechanism is located between the fixed base 1 and the movable base 101 and is distributed above the lower rotating mechanism. Multiple sets of lower straightening rollers 3 are detachably mounted on the lower rotating mechanism. The upper straightening roller 4 has the same structure as the lower straightening roller 3. The surfaces of the lower straightening roller 3 and the upper straightening roller 4 are covered with a polyurethane layer to reduce scratches on the stainless steel surface. The upper rotating mechanism has the same structure as the lower rotating mechanism. The upper rotating mechanism consists of multiple sets of drive shafts 2 that are driven to rotate and connected to the fixed base 1 by a drive component, and multiple sets of driven shafts 201 that are driven to rotate and connected to the moving base 101. The drive component is existing technology and can drive multiple sets of drive shafts 2 to rotate synchronously along the fixed base 1. The lower straightening roller 3 or the upper straightening roller 4 can be detachably installed between the drive shafts 2 and the driven shafts 201. The support mechanism consists of multiple sets of abutment seats 504 that can be raised and lowered and connected to the fixed base 1. The abutment seats 504 abut against the bottom end of the outer peripheral surface of the lower straightening roller 3 or the upper straightening roller 4.

[0020] Furthermore, the fixed base 1 is L-shaped, and a support base 106 is installed on the fixed base 1. A threaded rod 104 is threadedly connected to the support base 106. One end of the threaded rod 104 is rotatably connected to the movable base 101. A nut is threadedly connected to the threaded rod 104. The nut abuts against the support base 106 to limit the threaded rod 104 and prevent rotation without external force adjustment.

[0021] Furthermore, slots 202 are provided on both the drive shaft 2 and the driven shaft 201, and insert rods 301 are installed at the ends of the lower straightening roller 3 or the upper straightening roller 4. The insert rods 301 are inserted into the slots 202, and the insert rods 301 are square rods.

[0022] Furthermore, multiple sets of lower straightening rollers 3 and multiple sets of upper straightening rollers 4 are staggered between the fixed seat 1 and the movable seat 101 to increase the direct contact surface of the stainless steel coil and improve the straightening effect.

[0023] Furthermore, a first mounting seat 5 is installed on the bracket 102 via a first electric push rod. Multiple sets of first columns 501 are evenly installed on the top of the first mounting seat 5. A second mounting seat 502 is installed on the bracket 102 via a second electric push rod. Multiple sets of second columns 503 are evenly installed on the second mounting seat 502. Abutment seats 504 are installed on the top of both the second columns 503 and the first columns 501. Both the first columns 501 and the second columns 503 are slidably installed through the bottom of the fixed seat 1. The length of the first column 501 is less than the length of the second column 503. The abutment seats 504 on the first column 501 correspond to the lower straightening roller 3, and the abutment seats 504 on the second column 503 correspond to the upper straightening roller 4.

[0024] In this embodiment, the controller activates two sets of driving components to drive the upper and lower rotating mechanisms, thereby causing multiple sets of upper straightening rollers 4 to rotate synchronously in opposite directions. This feeds the stainless steel coil between the upper straightening roller 4 and the lower straightening roller 3. The rotating lower straightening roller 3 and upper straightening roller 4 then roll-straighten and convey the stainless steel coil. The straightening process is complete when the stainless steel coil is discharged from the output end. When the lower straightening roller 3 or upper straightening roller 4 experiences severe wear after prolonged use, the controller activates the first and second electric push rods to drive the corresponding first mounting base 5 and second mounting base 502 to slide upwards along the fixed base 1. This causes multiple sets of first columns 501 and second columns 503 to rise, thereby causing multiple sets of abutment seats 504 to contact the outer periphery of the corresponding lower straightening roller 3 or upper straightening roller 4. The ends abut against each other, thereby supporting the lower straightening roller 3 and the upper straightening roller 4 at the end closest to the moving seat 101. Then, rotating the threaded rod 104 can drive the moving seat 101 to slide and adjust horizontally along the fixed seat 1, thereby driving the driven shaft 201 on the moving seat 101 away from the lower straightening roller 3 and the upper straightening roller 4. At this time, the lower straightening roller 3 or the upper straightening roller 4 that needs to be replaced is moved horizontally so that the insertion rod 301 is pulled out from the slot 202 on the drive shaft 2, and the lower straightening roller 3 or the upper straightening roller 4 can be disassembled. The new lower straightening roller 3 or the upper straightening roller 4 is moved horizontally along the abutment seat 504 until the insertion rod 301 is inserted into the slot 202 in the drive shaft 2. Then, the moving seat 101 is moved toward the fixed seat 1 until the slot 202 on the driven shaft 201 is connected with the insertion rod 301, and the disassembly and assembly of the lower straightening roller 3 or the upper straightening roller 4 is completed.

[0025] Example 2

[0026] like Figures 1 to 3 As shown, the present invention proposes a straightening device for processing stainless steel coils. Compared with Embodiment 1, both the fixed seat 1 and the movable seat 101 are provided with clearance openings 105. Both the fixed seat 1 and the movable seat 101 are connected to lifting seats 103 through a third electric push rod. The lifting seats 103 are driven by the third electric push rod to adjust their height in the clearance openings 105. The upper rotation mechanism is set between the two sets of lifting seats 103.

[0027] In this embodiment, the lifting seat 103 is driven to move up or down along the clearance opening 105 by the third electric push rod. This can drive the upper rotating mechanism and multiple sets of upper straightening rollers 4 to move up or down for adjustment, thereby adjusting the distance between the upper straightening rollers 4 and the lower straightening rollers 3, which can be used to straighten stainless steel coils of different thicknesses.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
