Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a strip head processing device of a strip steel leveling unit. Background Art

[0002] Generally, tension rollers are set during strip leveling to increase the strip tension to improve the strip elongation and ensure the leveling quality. In addition, during the strip threading process, the strip is bent and deformed under the action of the tension rollers, causing the strip head to easily form a downward bending shape.

[0003] The uncoiler often uses the upper uncoil mode. If the strip head is in a downward curved shape and is threaded, it is easy to get stuck in the gap between the guide plates of the strip leveling unit, causing a large amount of strip piling and other abnormal conditions. This not only increases the abnormal loss of strip material, but also requires additional production time to handle abnormal conditions, reduces production efficiency, and makes it difficult to achieve automatic threading. Utility Model Content

[0004] Therefore, in order to solve the above problems, the utility model provides a strip head processing device for a strip leveling unit, which effectively processes the strip head shape to prevent the strip from getting stuck during the strip threading process and facilitates automatic strip threading.

[0007] Furthermore, the first mold is a male mold, and the second mold is a female mold.

[0008] Furthermore, the cross-sectional shape of the mold cavity of the female mold is unilaterally warped, and the cross-sectional shape of the mold cavity of the male mold matches the cross-sectional shape of the mold cavity of the female mold.

[0009] Furthermore, it also includes a fixed frame, which is provided with a lifting slide, and the left and right ends of the lifting frame are respectively assembled on the lifting slide to form a vertical sliding arrangement.

[0010] Furthermore, the driving unit is a hydraulic cylinder, which is fixedly mounted on the fixed frame. The fixed support has a mounting through hole passing through the upper and lower surfaces.

[0011] Furthermore, the fixed support is equipped with a first guide plate on the feeding side of the strip conveying direction.

[0012] Furthermore, the fixed support is equipped with a second guide plate on the discharge side of the strip conveying direction.

[0013] The technical solution provided by the utility model has the following beneficial effects:

[0014] The driving unit drives the lifting frame to rise and fall in a sliding manner to drive the first mold to approach or move away from the second mold, so as to clamp the strip head between the first mold and the second mold, thereby effectively processing the shape of the strip head to avoid the strip head from penetrating into the gap where the guide plate of the strip leveling unit is connected, thereby preventing the strip from getting stuck during the threading process and facilitating automatic threading.

[0019] 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. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figures 1 to 3As shown, the present embodiment provides a strip head processing device (hereinafter referred to as the strip head processing device) of a strip leveling machine group, the strip head processing device includes a fixed support 4, a slidably arranged lifting frame 1 and a driving unit cooperating with the lifting frame 1 for lifting, the lifting frame 1 and the fixed support 4 are arranged up and down, the lifting frame 1 is provided with a first mold 9, the fixed support 4 is provided with a second mold 10, the first mold 9 corresponds to the second mold 10, the driving unit drives the lifting frame 1 to drive the first mold 9 to approach or move away from the second mold 10, and forms a clamping arrangement for the strip head between the first mold 9 and the second mold 10.

[0022] In this embodiment, the first mold 9 is a male mold, and the second mold 10 is a female mold.

[0023] The driving unit drives the lifting frame 1 to descend, thereby driving the first mold 9 to descend until it abuts against the strip head located on the second mold 10, and applies a certain pressure to the strip head. The punch and the die cooperate to achieve the change of the shape of the strip head after clamping (e.g., the initial shape of the buckle bending changes to a clamping shape that is warped toward the strip outlet side after clamping), that is, plastic deformation occurs to meet the strip threading requirements of the strip leveling unit, so as to avoid the strip head from penetrating into the gap where the guide plates of the strip leveling unit are connected.

[0024] After the strip head is clamped and completes plastic deformation, the driving unit drives the lifting frame 1 to rise, so that the first mold 9 is away from the second mold 10 and the strip head, that is, the clamping is released to facilitate the strip to continue to enter the strip leveling unit.

[0025] The driving unit drives the lifting frame 1 to rise and fall in a sliding manner, so as to clamp the strip head between the first mold 9 and the second mold 10, thereby effectively processing the shape of the strip head and effectively preventing the strip head from penetrating into the gap where the guide plate of the strip leveling unit is connected, so as to prevent the strip from getting stuck during the threading process and facilitate automatic threading.

[0026] Further preferably, when the uncoiler is in the upper uncoiling mode, the cross-sectional shape of the cavity of the concave mold (i.e., the second mold 10) is as follows: Figure 4 The single side shown is warped upward, and the cross-sectional shape of the mold cavity of the male mold matches the cross-sectional shape of the mold cavity of the female mold. After the strip head is clamped, the strip head is extruded according to the preset mold cavity shapes of the male and female molds, that is, the molding effect of the strip head warping upward.

[0027] Of course, in other embodiments, the cross-sectional shapes of the cavities of the first mold 9 and the second mold 10 are not limited thereto, and are determined according to actual conditions on site (such as the unwinding mode of the unwinding machine).

[0028] In another preferred embodiment, Figure 1 As shown, the strip head processing device also includes a fixed frame 3, which is provided with a lifting slide 2. The left and right ends of the lifting frame 1 are respectively assembled on the lifting slides 2 of the two fixed frames 3 to form a vertical sliding setting to ensure the stability of the up and down movement posture of the lifting frame 1, thereby ensuring that the strip head is tightly clamped or squeezed by the first mold 9 and the second mold 10 to ensure the stability of the clamping shape.

[0029] More specifically, the driving unit is two hydraulic cylinders 5, which are fixedly mounted on a fixed frame 3. A fixed support 4 has mounting holes that penetrate the upper and lower surfaces. The piston rods of the hydraulic cylinders 5 can movably pass through the mounting holes of the fixed support 4 and are fixedly connected to the lifting frame 1, so that the lifting frame 1 and the piston rods of the hydraulic cylinders 5 are fixed together and move synchronously.

[0030] In this specific embodiment, two hydraulic cylinders 5 are symmetrically arranged on the left and right and fixed below the fixed support 4 .

[0031] Before threading the belt, the piston rod of the hydraulic cylinder 5 extends upward, driving the lifting frame 1 to rise vertically to open the distance between the first mold 9 and the second mold 10, and then the belt head is placed on the mold cavity of the second mold 10, and then the piston rod of the hydraulic cylinder 5 is retracted downward, driving the lifting frame 1 to descend vertically until the belt head located between the first mold 9 and the second mold 10 is tightly clamped or squeezed to complete the clamping deformation. At this time, the belt head is extruded and formed according to the preset mold cavity shape of the convex and concave molds, that is, the belt head has a forming effect of upward warping.

[0032] More specifically, Figure 2 As shown, the fixed support 4 is equipped with a first guide plate 7 on the feeding side of the strip conveying direction (i.e., the front side of the fixed support 4), and the fixed support 4 is equipped with a second guide plate 8 on the discharging side of the strip conveying direction (i.e., the rear side of the fixed support 4). The first guide plate 7 and the second guide plate 8 are arranged in the front and rear, and the strip is transported along the extension direction of the first guide plate 7 and the second guide plate 8 to guide the strip.

[0033] Of course, in other embodiments, the number of hydraulic cylinders 5 can also be 4 or 6, and the hydraulic cylinders 5 are symmetrically distributed on both sides of the fixed support 4 along the conveying direction of the strip steel, and then the piston rod of the hydraulic cylinder 5 is directly fixed on the lifting frame 1, so that the lifting frame 1 can also be driven to achieve clamping.

[0034] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
