Description

Technical Field

[0001] The present invention relates to a bimetal wire metal rubber winding device and its working method. Background Art

[0002] The existing damping materials are mainly polymer damping materials. The preparation process of polymer damping materials is simple and the cost is low. However, polymer damping materials are not resistant to high and low temperatures and are prone to aging. Therefore, their service life is short, they need to be replaced frequently, which increases the maintenance cost. Moreover, the failure of polymer damping materials will have a greater impact on the equipment.

[0003] Metal rubber is a new type of porous damping material. Metal rubber is only made by winding metal wires. Therefore, it has the advantages of being resistant to high and low temperatures, radiation, and having a long service life. In addition, due to the porous characteristics of metal rubber, metal rubber has both high strength and certain damping characteristics. However, the existing metal rubber is only wound by metal wires of a single diameter, resulting in low damping performance. The main reason is that the existing equipment can only wind one metal wire at a time, and the stretching of the metal wire of the equipment is uneven. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a bimetal wire metal rubber winding device and its working method to solve the problems existing in the above technical solutions.

[0005] The present invention is implemented as follows: A bimetal wire metal rubber winding device includes a base. On both sides of the base, a chuck and a fastener are respectively arranged. A mandrel is clamped on the chuck. One end of the mandrel is fixed in the chuck, and the other end is fixed in the fastener. Tensile mechanisms are symmetrically arranged on the left and right sides of the mandrel. At least two distance-adjusting turntable pairs are installed on the tensile mechanisms. The winding metal wire is wound around the mandrel through the distance-adjusting turntable pairs on the same-side tensile mechanism.

[0006] Further, the tensile mechanism includes a tensile frame. On the upper surface of the tensile frame, at least two distance-adjusting turntable pairs are arranged at intervals in a direction perpendicular to the mandrel. The distance-adjusting turntable pair includes horizontal turntables symmetrically arranged on the left and right sides of the winding metal wire. The periphery of the horizontal turntable abuts against the outer periphery of the winding metal wire.

[0007] Further, a driving motor for driving the horizontal turntable to rotate is installed in the tensile frame. The driving motor is slidably connected to the tensile frame in a direction perpendicular to the length direction of the winding metal wire.

[0008] Furthermore, the driving motor is slidably connected to the stretching frame through a motor fixing frame, and adjusting bolts are provided on the stretching frame at the left and right sides of the winding metal wire corresponding to the motor fixing frames. The adjusting bolts are screwed to the side of the stretching frame, and the extending end of the adjusting bolt extending into the stretching frame is sleeved on the motor fixing frame.

[0009] Furthermore, the horizontal turntable is a grooved wheel.

[0010] Furthermore, a clearance groove for movement is provided on the motor fixing frame corresponding to the connecting shaft between the driving motor and the horizontal turntable.

[0011] Furthermore, the base is symmetrically provided with slide rails parallel to the core shaft on the left and right sides of the core shaft, and the stretching machine frame is slidably connected to the slide rails.

[0012] Furthermore, the chuck is driven to rotate by an external motor.

[0013] A working method of a bimetallic wire metal rubber winding device:

[0014] The external motor drives the rotation of the core shaft, and the stretching mechanisms on both sides gradually move on the slide rails to transport the winding metal wire to the core shaft to realize the winding of the metal rubber. At the same time, by controlling the moving speed of the stretching mechanism and the rotation of the core shaft, the winding angle and winding length of the wound metal rubber blank can be controlled.

[0015] Furthermore, by screwing out or screwing in the adjusting bolt, the distance between the two horizontal turntables on the same pitch-adjusting turntable pair is controlled, thereby achieving fixed-pitch stretching of the metal wire, and at the same time, the winding metal wire is stretched in a step-by-step manner. The winding metal wire passes through the first pitch-adjusting turntable pair to stretch the tightly combined spiral metal wire to a smaller pitch, and then passes through the second pitch-adjusting turntable to stretch the smaller pitch to the required pitch.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1) The present invention realizes the constant pitch stretching of the spiral coil in the form of a turntable pair, enabling the spiral coil to be stretched at equal distances, solving the drawbacks of traditional manual stretching of metal rubber, improving the consistency of metal rubber, and greatly improving production efficiency; 2) The double stretching mechanism realizes the stretching of double metal wires. Among them, the double metal wires can select metal wires with different wire diameters to increase the friction between the metal wires inside the metal rubber, thereby improving the damping energy dissipation performance of the metal rubber. The double metal wires can also select metal wires with different materials to meet the requirements for the comprehensive mechanical properties of metal rubber. For example, copper wires and stainless steel wires are used to enable the metal rubber to not only maintain high strength characteristics but also increase the electrical conductivity of the metal rubber; 3) By adjusting the rotation speed of the mandrel and the sliding speed of the stretching mechanism on the slide rail, the winding of different metal rubber angles can be realized, achieving the adjustability of the stiffness and damping of the metal rubber, and greatly expanding the application range of the metal rubber.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] As Figures 1-3 shown, a bimetal wire metal rubber winding device includes a base. On both sides of the base, a chuck and a fastener are respectively arranged. A mandrel is clamped on the chuck. One end of the mandrel is fixed inside the chuck, and the other end is fixed inside the fastener. Tensioning mechanisms are symmetrically arranged on the left and right sides of the mandrel. At least two distance-adjusting turntable pairs are installed on the tensioning mechanisms. The winding wire is wound around the mandrel through the distance-adjusting turntable pairs on the same-side tensioning mechanism. The fastener is an existing clamping fastener. Since it is a conventional prior art, it will not be described in detail here.

[0027] In this embodiment, the tensioning mechanism includes a tensioning frame. At least two distance-adjusting turntable pairs are arranged at intervals on the upper surface of the tensioning frame along the direction perpendicular to the mandrel. The distance-adjusting turntable pair includes horizontal turntables symmetrically arranged on the left and right sides of the winding wire. The periphery of the horizontal turntable abuts against the outer periphery of the winding wire, and fixed-distance tensioning is achieved through the horizontal turntable.

[0028] In this embodiment, a driving motor for driving the horizontal turntable to rotate is installed inside the tensioning frame. The driving motor is slidably connected to the tensioning frame along the direction perpendicular to the length of the winding wire.

[0029] In this embodiment, the driving motor is slidably connected to the inside of the tensioning frame through a motor fixing frame. Adjusting bolts are arranged on the tensioning frame corresponding to the motor fixing frame on the left and right sides of the winding wire. The adjusting bolts are screwed on the side of the tensioning frame. The extending end of the adjusting bolt extending into the tensioning frame is sleeved on the motor fixing frame. Specifically, the end of the adjusting bolt can be provided with a smooth shaft of a certain length, and an annular arc-section convex shoulder is arranged on the outer periphery of the smooth shaft. A clearance sleeve is provided on the motor fixing frame corresponding to the smooth shaft. The smooth shaft is sleeved in the clearance sleeve, and an annular arc-section groove is arranged on the inner wall of the clearance sleeve corresponding to the arc-section convex shoulder. Through the clamping fit between the arc-section groove and the arc-section convex shoulder, the adjusting bolt can drag the motor fixing frame. Of course, other similar screw mechanisms can also be used to realize the movement of the motor fixing frame. At the same time, a chute can be arranged inside the tensioning frame corresponding to the movement track of the motor fixing frame.

[0030] In this embodiment, for reasonable design, the horizontal turntable is a grooved wheel disc, which is convenient for the wheel groove to limit the winding wire and avoid the winding wire from slipping out of the horizontal turntable.

[0031] In this embodiment, a relief groove (not shown) for the movement of the connecting shaft corresponding to the driving motor and the horizontal turntable is provided on the motor fixing bracket. That is, the horizontal turntable is located on the upper surface of the stretching frame, and the driving motor is located inside the stretching frame. In order to avoid interference with the rotating shaft of the horizontal turntable, the relief groove is provided.

[0032] In this embodiment, slide rails parallel to the mandrel are symmetrically arranged on both the left and right sides of the mandrel on the base. The stretching frame is slidably connected to the slide rails. The stretching frame can move on the slide rails by means of screw drive. At the same time, an existing movement controller can be provided on the base to control the movement speed and movement distance of the stretching frame. The controller only needs to control the rotation speed and opening / closing of the screw. The control method is prior art, so it will not be elaborated here.

[0033] In this embodiment, for reasonable design, the chuck is driven to rotate by an external motor. A rotating seat can be provided on the base, and the chuck is rotatably connected inside the rotating seat. The chuck is connected by an external motor to achieve rotation, similar to the rotation of the chuck of an existing lathe. This is prior art, so it will not be elaborated here.

[0034] A working method of a bimetal wire metal rubber winding device:

[0035] The external motor drives the rotation of the mandrel, and the stretching mechanisms on both sides gradually move on the slide rails, conveying the winding metal wires 101\102 on both sides to the mandrel to realize the winding of the metal rubber. At the same time, by controlling the movement speed of the stretching mechanism and the rotation of the mandrel, the winding angle and winding length of the metal rubber blank after winding can be controlled.

[0036] In this embodiment, by screwing out or screwing in the adjusting bolts 701\703, the distance between the two horizontal turntables on the same pitch adjusting turntable pair is controlled, thereby realizing the fixed-pitch stretching of the metal wire. At the same time, the stretching of the wound metal wire is realized in a step-by-step form. The wound metal wire is fixed-pitch stretched to a smaller pitch by the first pitch adjusting turntable pair 702, and then stretched to the required pitch by the second pitch adjusting turntable 704.

[0037] A double-stretching mechanism is adopted to realize the stretching and winding of the bimetal wire metal rubber. Each stretching mechanism can be controlled by a controller to have different sliding speeds. Different wire diameters of metal wires can be selected for the bimetal wire to improve the better meshing inside the metal rubber and increase the friction between the metal wires inside the metal rubber, thereby improving the friction energy dissipation ability of the metal rubber. In addition, two different materials of metal wires can also be selected according to actual needs to meet the requirements of the comprehensive mechanical properties of the metal rubber. For example, stainless steel metal wires and copper wires are used to make the metal rubber not only maintain high strength characteristics but also increase the electrical conductivity of the metal rubber.

Any person skilled in the art should understand that the preferred numerical range is only the numerical values with obvious technical effects or representativeness among many implementable numerical values. Since there are too many numerical values to enumerate, the present invention only discloses some numerical values to illustrate the technical solutions of the present invention. Moreover, the listed numerical values should not constitute a limitation on the protection scope of the present invention.

[0039] If terms such as "first" and "second" are used in this article to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing components in description. Unless otherwise stated, the above terms have no special meaning.

[0040] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or it can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured by integral casting process) (except when it is obviously impossible to adopt the integral forming process).

[0041] In addition, for the orientation or positional relationship indicated by terms used to represent positional relationships in any of the technical solutions disclosed by the present invention, such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., it is based on the orientation or positional relationship shown in the drawings.

Therefore, it should not be understood as a limitation to this patent. Moreover, for the terms used to represent shapes in any of the technical solutions disclosed by the present invention, unless otherwise stated, their meanings include shapes that are approximate, similar or close to them.
