Description

Technical Field

[0001] This utility model relates to the field of material coil winding technology, and in particular to a tensioning device for the winding process of metal material coils. Background Technology

[0002] The existing material strip can only adjust the tension of the roll during the winding process by relying on the winding tension of the material strip. However, during the winding process, the material strip itself also has a force to resist deformation. As winding continues, this force to resist deformation will accumulate. Therefore, the winding force of the roll and the force of the roll's own expansion coexist, making it difficult for the material strip to tighten. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a tensioning device for the winding process of metal strips, so as to solve the problem of tensioning of the strip during the winding process.

[0004] To solve the above-mentioned technical problems, this utility model provides a tensioning device for the winding process of metal coils, including: a pressing drive (1), a horizontal opening module (2), and a bearing platform (3). Multiple horizontal opening modules (2) are provided, and each horizontal opening module (2) includes an arc-shaped tensioning panel (21) and a wedge-shaped drive block (22). The wedge-shaped drive block (22) is connected to the inner side of the arc-shaped tensioning panel (21). Multiple horizontal opening modules (2) are evenly distributed around the circumference of the pressing drive (1). It is arranged in a circular shape, and the two adjacent arc-shaped tensioning panels (21) retain a gap; the inner side of the wedge-shaped drive block (22) is arranged at an angle and is equipped with a guide rail (23); correspondingly, the pressing drive component (1) includes a tensioning ring (11) and a plurality of pressing sliders (13) arranged on the circumference of the tensioning ring (11). The tensioning ring (11) is cylindrical and is arranged vertically on the upper part of the central axis of the plurality of horizontally opening modules (2). The pressing sliders (13) are slidably connected to the guide rail (23).

[0005] The angle between the inner side of the wedge-shaped drive block (22) and the horizontal plane is between 60 and 85 degrees.

[0006] The pressing drive (1) further includes a pressing wedge connector (12), which is wedge-shaped and parallel to the inner side of the wedge drive block (22).

[0007] The pressure drive (1) further includes an extension screw (14) and a pressure plate (15), the pressure plate (15) being fixedly connected to the tensioning ring (11) by a plurality of extension screws (14).

[0008] The lower pressure plate (15) can receive the driving force of the cylinder to make a vertical extension and retraction movement, drive the entire lower pressure drive component (1) to move in the vertical direction, and thus drive the horizontal opening module (2) to make an expansion or retraction action on the horizontal surface.

[0009] The pressing slider (13) and the guide rail are connected by a T-slot or dovetail groove structure so that they can only move relative to each other in the sliding direction, while locking each other in other directions.

[0010] The wedge-shaped drive block (22) has a downward protruding protrusion (221) at its bottom, and the protrusion (221) is connected to the slide groove (31) on the bearing platform (3); the slide groove (31) is arranged radially around the pressing drive member (1).

[0011] At least one of the arc-shaped tensioning panels (21) has an inclined material-holding groove (211) and a straight groove (212) that runs through the upper and lower ends on its outer arc surface.

[0012] The metal coil winding tensioning device provided by this utility model can drive the horizontal opening module to open outwards on a horizontal plane by pressing down the driving component. This allows the strip to be tensioned on the horizontal opening module during the winding process. After the strip is wound, the horizontal opening module can be separated from the coil by retracting the driving component upwards. The metal coil winding tensioning device provided by this utility model can finely adjust the tension of the coil by the inclined structure arrangement of the wedge-shaped driving block and the pressing wedge connector, as well as the relative action of the guide rail and the pressing slider.

Detailed Implementation

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1-4 As shown, this utility model provides a tensioning device for the winding process of metal coils, including: a pressing drive 1, a horizontal opening module 2, and a supporting platform 3. Multiple horizontal opening modules 2 are provided, and each horizontal opening module 2 includes an arc-shaped tensioning panel 21 and a wedge-shaped drive block 22. The wedge-shaped drive block 22 is connected to the inner side of the arc-shaped tensioning panel 21. The multiple horizontal opening modules 2 are evenly distributed around the circumference of the pressing drive 1 and arranged in a circular pattern, with a gap maintained between adjacent arc-shaped tensioning panels 21. The inner side of the wedge-shaped drive block 22 is inclined and is equipped with a guide rail 23 (the guide rail 23 can be fixedly connected to the wedge-shaped drive block 22 by screws). Correspondingly, the pressing drive 1 includes a tensioning ring 11 and multiple pressing sliders 13 arranged around the circumference of the tensioning ring 11. The tensioning ring 11 is cylindrical and vertically arranged above the central axis of the multiple horizontal opening modules 2. The pressing sliders 13 are slidably connected to the guide rails 23.

[0022] The angle between the inner side of the wedge-shaped drive block 22 and the horizontal plane is between 60 and 85 degrees, so that the vertical drive stroke of the pressing drive 1 is slowly transformed into the horizontal opening stroke of the horizontal opening module 2 (the vertical drive stroke of the pressing drive 1 is much larger than the horizontal opening stroke of the horizontal opening module 2), thereby allowing for more precise adjustment of the opening amplitude of the horizontal opening module.

[0023] The pressing drive component 1 also includes a pressing wedge connector 12, which is wedge-shaped and parallel to the inner side of the wedge drive block 22. The pressing wedge connector 12 can be fixedly connected to the outer circumference of the tensioning ring 11 by welding or screw riveting.

[0024] The pressing drive component 1 also includes an extension screw 14 and a pressing plate 15, wherein the pressing plate 15 is fixedly connected to the tensioning ring 11 through a plurality of extension screws 14.

[0025] The lower pressure plate 15 can receive the driving force of the cylinder to make a vertical extension and retraction movement, drive the entire lower pressure drive 1 to move in the vertical direction, and thus drive the horizontal opening module 2 to make an expansion or retraction movement on the horizontal plane.

[0026] The pressing slider 13 and the guide rail are connected by a T-slot or dovetail groove structure so that they can only move relative to each other in the sliding direction, while locking each other in other directions. In particular, when the pressing drive 1 retracts upward, it can synchronously drive the horizontal opening module to retract inward.

[0027] The bottom of the wedge-shaped drive block 22 is provided with a downward protruding protrusion 221, which is connected to the slide groove 31 on the bearing platform 3; the slide groove 31 is arranged radially around the downward drive member 1.

[0028] At least one of the arc-shaped tensioning panels 21 has an inclined material-holding groove 211 and a straight groove 212 that runs through both the upper and lower ends on its outer arc surface.

[0029] The metal coil winding tensioning device provided by this utility model can drive the horizontal opening module to open outwards on a horizontal plane by pressing down the driving component. This allows the strip to be tensioned on the horizontal opening module during the winding process. After the strip is wound, the horizontal opening module can be separated from the coil by retracting the driving component upwards. The metal coil winding tensioning device provided by this utility model can finely adjust the tension of the coil by the inclined structure arrangement of the wedge-shaped driving block and the pressing wedge connector, as well as the relative action of the guide rail and the pressing slider.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
