[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to cutting equipment is also constantly improving. High-strength rust-proof steel strips need to go through multiple processes during processing. When cutting high-strength rust-proof steel strips, steel strip cutting equipment is required.

[0003] The patent document with publication number "CN217254384U" discloses a high-strength rust-proof steel strip cutting device, including a base plate, and an unwinding device, a flattening device and a cutting machine body are installed on the top surface of the base plate from left to right.

[0004] Although the aforementioned patent documents have solved the problems of existing strip cutting devices being unable to roll the uncoiled strip, the strip being uneven after uncoiling, and reducing cutting accuracy, the following drawbacks still exist: after using hoisting equipment to lift the strip coil and place its shaft in the inner cavity of the notch, it is necessary to manually use bolts to position and lock it, which is cumbersome, inconvenient, and time-consuming. This results in low cutting efficiency for high-strength rust-proof strip steel and is not conducive to the use of the cutting device. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: after using hoisting equipment to lift the steel strip coil and place its shaft in the inner cavity of the placement notch, it is necessary to manually use bolts to position and lock it, which is cumbersome, inconvenient and time-consuming. This results in low cutting efficiency of high-strength rust-proof steel strip and is not conducive to the use of cutting devices. Therefore, a high-strength rust-proof steel strip cutting device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-strength rust-proof steel strip cutting device includes a base plate, two support plates fixedly mounted on the base plate, and a cutting machine body. Each support plate is rotatably connected to a rotating shaft. A rectangular cavity is formed inside the rotating shaft. A rectangular rod is slidably connected inside the rectangular cavity. One end of the rectangular rod is fixedly connected to an installation block. A clamping opening with an isosceles trapezoidal cross-section is formed inside the installation block. A fastening pad is fixedly connected to the inner wall of the clamping opening.

[0008] The base plate is provided with a load-bearing component, and a first motor is fixedly installed on one of the support plates. The drive end of the first motor is fixedly connected to a bidirectional lead screw, and two hangers are threadedly connected to the bidirectional lead screw. Each mounting block is provided with an annular groove for connecting the hangers.

[0009] Preferably, the bearing assembly includes an electric push rod fixedly mounted on the base plate, the drive end of the electric push rod is fixedly connected to a Z-shaped frame, and two bearing plates are fixedly connected to the Z-shaped frame, each bearing plate having an arc-shaped opening.

[0010] Preferably, a fixing rod is fixedly connected between the two support plates, and both hangers are slidably connected to the fixing rod.

[0011] Preferably, a bracket is fixedly connected to one of the support plates, a second motor is fixedly connected to the bracket, and one end of one of the rotating shafts is fixedly connected to the drive end of the second motor.

[0012] Preferably, each of the rotating shafts is fixedly connected to two rotating rings, and the surfaces of the two rotating rings are respectively attached to the two side surfaces of the support plate.

[0013] Preferably, each of the hangers has a plurality of balls rotatably connected to its inner surface, and the plurality of balls are in contact with the inner wall of the corresponding annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, the steel coil is lifted by hoisting equipment, and its shaft is placed inside the two arc-shaped openings. Then, the first motor drives the bidirectional lead screw to rotate, reducing the distance between the two hangers. The two mounting blocks move synchronously. During the movement of each mounting block, its clamping port gradually fits onto the outside of one end of the shaft until the outer surface of the shaft end is in close contact with the rubber fastening pad. The friction between the fastening pad and the shaft is relatively large. After both ends of the shaft are in close contact with the corresponding fastening pad, the shaft can be automatically positioned and locked without the need for manual positioning and locking with bolts. The operation is more convenient and faster, and the time consumption is shorter, which makes the cutting efficiency of high-strength rust-proof steel strip higher and is beneficial to the use of the cutting device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A high-strength rust-proof steel strip cutting device includes a base plate, two support plates 1 fixedly mounted on the base plate, and a cutting machine body 2. Each support plate 1 is rotatably connected to a rotating shaft 16. A rectangular cavity is formed inside the rotating shaft 16, and a rectangular rod 15 is slidably connected inside the rectangular cavity. One end of the rectangular rod 15 is fixedly connected to a mounting block 7. The mounting block 7 has a clamping opening 10 with an isosceles trapezoidal cross-section. A fastening pad 9 is fixedly connected to the inner wall of the clamping opening 10. A load-bearing component is provided on the base plate. A first motor is fixedly mounted on one of the support plates 1. A bidirectional lead screw 5 is fixedly connected to the drive end of the first motor. Two hangers 13 are threadedly connected to the bidirectional lead screw 5. Each mounting block 7 has an annular groove 14 for connecting the hangers 13.

[0023] refer to Figure 2 The supporting components include an electric push rod 3 fixedly mounted on the base plate. The drive end of the electric push rod 3 is fixedly connected to a Z-shaped frame 4. Two support plates 8 are fixedly connected to the Z-shaped frame 4. Each support plate 8 has an arc-shaped opening 11. The inner wall of the arc-shaped opening 11 is relatively smooth. After the high-strength rust-proof strip steel on the shaft is uncoiled, the locking treatment at both ends of the shaft is released, that is, both mounting blocks 7 are located on the outside of the shaft. The electric push rod 3 drives the Z-shaped frame 4 to move, which can then move the shaft inside the arc-shaped opening 11 out from between the two support plates 1. After that, the shaft can be quickly removed by a robot or manually. The operating space is large and the operation is less restricted.

[0024] refer to Figure 2A fixed rod 17 is fixedly connected between the two support plates 1. Both hangers 13 are slidably connected to the fixed rod 17. The fixed rod 17 can limit the movement trajectory of the hangers 13 and effectively prevent the hangers 13 from swinging. A bracket 6 is fixedly connected to one of the support plates 1. A second motor is fixedly connected to the bracket 6. One end of one of the rotating shafts 16 is fixedly connected to the drive end of the second motor. After both ends of the shaft are tightly attached to the corresponding fastening pads 9, the second motor drives the rotating shaft 16 to rotate, which can drive the shaft and the other rotating shaft 16 to rotate synchronously, thereby realizing the unwinding of the steel coil.

[0025] refer to Figure 3 Two rotating rings 12 are fixedly connected to each rotating shaft 16. The surfaces of the two rotating rings 12 are respectively in contact with the two side surfaces of the support plate 1. The friction between each rotating ring 12 and the support plate 1 is small. The rotating rings 12 can restrict the movement of the rotating shaft 16 and prevent the rotating shaft 16 from sliding relative to the support plate 1 along the axial direction. Multiple balls are rotatably connected to the inner surface of each hanger 13. The multiple balls are in contact with the inner wall of the corresponding annular groove 14. The surface of the balls is relatively smooth, and the friction between the mounting block 7 and the balls is small when the mounting block 7 rotates.

[0026] In this utility model, reference is made to Figure 2 and Figure 3 In use, the steel coil is lifted by hoisting equipment, and its shaft is placed inside the two arc-shaped openings 11. At this time, the two ends of the shaft are located on the opposite side of the two clamping openings 10. Then, the first motor drives the bidirectional lead screw 5 to rotate, and the two hangers 13 move simultaneously along the bidirectional lead screw 5, and the distance between the two hangers 13 decreases. Under the transmission action of the hangers 13, the two mounting blocks 7 move synchronously. During the movement of each mounting block 7, its clamping opening 10 will gradually fit on the outside of one end of the shaft until the outer surface of the shaft end is in close contact with the rubber fastening pad 9. The friction between the fastening pad 9 and the shaft is large. After both ends of the shaft are in close contact with the corresponding fastening pad 9, the shaft can be positioned and locked. There is no need to manually use bolts to position and lock it. The operation is more convenient and quick, and the time consumption is shorter. This makes the cutting efficiency of high-strength rust-proof steel strip higher, which is beneficial to the use of the cutting device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
