[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The utility model provides a strip steel clamping device, such as Figure 1 and 2 As shown, it includes a workbench 1, a lower pressing plate platform 3, an upper pressing plate platform 2, a guide mechanism 4 and a driving mechanism;

[0028] The lower pressing plate 3 is fixedly arranged on the workbench 1, providing a stable basic support. The upper pressing plate 2 is movably arranged on the workbench 1 through the guide mechanism 4, and is located above the lower pressing plate 3. A passage for the strip to pass through is formed between the upper pressing plate 2 and the lower pressing plate 3, so that the strip can pass through the device smoothly.

[0029] like Figure 2 As shown, the fixed end of the driving mechanism is hidden in the workbench 1. This design not only reduces the interference of the external environment on the driving mechanism, but also improves the aesthetics and neatness of the entire device. The output end of the driving mechanism is connected to and drives the upper pressing plate 2 to make linear reciprocating motion along the guide mechanism 4. When the strip steel needs to be clamped, the driving mechanism moves the upper pressing plate 2 downward along the guide mechanism 4, close to the lower pressing plate 3, thereby clamping the strip steel; when the strip steel needs to be loosened, the driving mechanism moves the upper pressing plate 2 upward along the guide mechanism 4, away from the lower pressing plate 3, to achieve the loosening of the strip steel.

[0030] The upper clamping plate assembly 6 is provided on the upper pressing plate platform 2, and the lower clamping plate assembly 7 is provided on the lower pressing plate platform 3. The upper clamping plate assembly 6 and the lower clamping plate assembly 7 are in contact with the upper and lower surfaces of the steel strip respectively when clamping the steel strip. When the steel strip is clamped, the upper clamping plate assembly 6 and the lower clamping plate assembly 7 are in close contact with the upper and lower surfaces of the steel strip respectively, forming a stable clamping force to prevent the steel strip from moving or deviating during processing.

[0031] like Figure 1As shown, the guide mechanism 4 includes a guide column 41 and a slide plate 42. A guide column 41 is provided on each side of the workbench 1, and these guide columns 41 provide a stable support structure for the entire clamping device. Guide grooves (not shown in the figure) extending in the vertical direction are provided on the guide column 41. These guide grooves have smooth surfaces and precise dimensions, ensuring that the slide plate 42 can slide smoothly and without jamming inside them. The slide plate 42 is an important component connecting the upper platen 2 and the guide groove. The slide plate 42 is firmly mounted on the bottom of the upper platen 2, and its shape and size match the guide groove, so that the slide plate 42 can be tightly embedded in the guide groove. When the driving mechanism starts working, it drives the upper platen 2 to move. In this process, the slide plate 42 performs precise linear reciprocating motion along the guide column 41 under the constraint of the guide groove. This design ensures that the upper platen 2 can move smoothly and accurately along the predetermined trajectory when clamping or releasing the strip. The close fit between the slide plate 42 and the guide groove, as well as the stable support of the guide column 41, together ensure the high precision and stability of the clamping device, thereby improving the quality and efficiency of strip processing.

[0032] like Figure 1 As shown, the upper clamping plate assembly 6 includes an upper clamping plate 61 and an upper lining plate 61, the upper clamping plate 61 is fixed on the upper platen platform 2, and the upper lining plate 61 is embedded in the upper clamping plate 61. Similarly, the lower clamping plate assembly 7 includes a lower clamping plate 71 and a lower lining plate 72, the lower clamping plate 71 is fixed on the lower platen platform 3, and the lower lining plate 72 is embedded in the lower clamping plate 71. In the process of clamping the strip steel, the upper lining plate 61 and the lower lining plate 72 play a vital role. When the driving mechanism drives the upper platen platform 2 to move downward so that the upper platen platform 2 is close to the lower platen platform 3 to clamp the strip steel, the upper lining plate 61 and the lower lining plate 72 will be in close contact with the upper surface and the lower surface of the strip steel respectively. This design ensures that the strip steel is subjected to uniform force during the clamping process and prevents the surface of the strip steel from being damaged due to improper clamping.

[0033] In this embodiment, in order to improve the clamping effect and protect the surface of the steel strip, hardwood is specially selected as the material of the upper lining plate 61 and the lower lining plate 72. Hardwood has the characteristics of high hardness, good wear resistance, and not easy to deform, which can effectively prevent the steel strip from being damaged due to uneven force or excessive friction during the clamping process. At the same time, the hardwood lining can also improve the durability and service life of the clamping device.

[0034] The number of driving mechanisms for driving the upper platen 2 can be one group, or multiple groups can be configured according to needs. In this embodiment, considering stability and balance, the number of the driving mechanisms is two groups, such as Figure 1 As shown, two sets of driving mechanisms are symmetrically arranged on the left and right sides of the workbench 1, and independently drive the left and right sides of the upper platen 2. However, no matter how many sets of driving mechanisms there are, the fixed ends of the driving mechanisms are hidden inside the workbench 1.

[0035] In order to achieve connection and power transmission between the driving mechanism and the upper platen platform 2, the output end of each set of driving mechanisms is connected to the upper platen platform 2 through a connecting plate 8, and the connection method can be bolt thread connection, but is not limited to this.

[0036] In this embodiment, the driving mechanism selected is a hydraulic cylinder 5. The hydraulic cylinder 5 has the advantages of simple structure, stable operation, large output force and easy control, and is very suitable for this clamping device that requires high-precision control. Specifically, the cylinder body 51 of the hydraulic cylinder 5 is hidden inside the workbench 1, and the piston rod 52 of the hydraulic cylinder 5 is connected to the upper platen 2 through the connecting plate 8. When the hydraulic cylinder 5 is working, the telescopic movement of the piston rod 52 is transmitted to the upper platen 2 through the connecting plate 8, thereby driving the upper platen 2 to reciprocate up and down, thereby clamping and loosening the strip.

[0037] In this embodiment, the design of the strip clamping device fully considers the needs of rolling operation and strip threading operation. First, the distance between the lower clamping plate assembly 7 and the rolling elevation is 15mm. This setting is to ensure that when rolling the strip, the lower clamping plate assembly 7 cooperates more closely with the rolling equipment, improves the stability of the rolling process and the quality of the strip. When rolling the strip, the opening of the upper and lower clamping plate assemblies 7 is set to 60mm. The appropriate opening can ensure that the strip is clamped evenly during the rolling process, and prevent the deformation of the strip caused by too tight clamping or the slipping caused by too loose clamping. In addition, during the strip threading operation, the strip needs to pass through the clamping device smoothly. Therefore, the opening of the upper and lower pressure plates needs to be adjusted to a larger value so that the strip can pass smoothly. In this embodiment, the opening of the upper and lower pressure plates during strip threading is set to 185mm. This opening is large enough to accommodate strips of various sizes, and also ensures the smooth progress of the strip threading operation.

[0038] The working process of the strip steel clamping device of the utility model is as follows:

[0039] First, the device is in standby mode, at which time the piston rods 52 of the two sets of hydraulic cylinders 5 are in the initial position, and a certain distance is maintained between the upper platen 2 and the lower clamping surface to allow the strip to enter freely;

[0040] When the strip needs to be clamped, the control system starts the hydraulic cylinder 5. The piston rods 52 of the two groups of hydraulic cylinders 5 start to move synchronously under the action of hydraulic oil, causing the upper platen 2 to move downward; as the upper platen 2 descends, it gradually approaches and finally contacts the upper surface of the strip. At this time, the hydraulic cylinder 5 continues to work, causing the upper platen 2 to apply a certain pressure to the strip, so that it is tightly clamped between the lower clamping surface and the upper platen 2. Since the output force of the hydraulic cylinder 5 can be accurately adjusted by the control system, it can ensure that the strip is clamped firmly and will not be damaged by excessive pressure.

[0041] After the strip is clamped, the whole device enters the clamping state. At this time, the upper platen 2 maintains the clamping force on the strip to ensure that the strip remains stable in subsequent operations.

[0042] When the strip needs to be released, the control system starts the hydraulic cylinder 5 again. The piston rods 52 of the two groups of hydraulic cylinders 5 move synchronously again under the action of the hydraulic oil, thereby driving the upper platen 2 to gradually rise. As the upper platen 2 rises, its clamping force on the strip gradually decreases until the strip is completely released.

[0043] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.
