Description

Technical Field

[0001] This utility model belongs to the field of tin-phosphor bronze strip production technology, specifically relating to tin-phosphor bronze strip winding, and particularly to coils for cold rolling of high yield strength and high elasticity tin-phosphor bronze strip. Background Technology

[0002] Because the production process of high yield strength and high elasticity tin phosphor bronze strip requires multiple cold rolling processes, it is necessary to carry out repeated winding and unwinding operations. In the traditional coil winding process, the outermost copper strip needs to be pressed by the pressure rollers on the winding device to keep it neat and tight.

[0003] However, existing coiling devices have the following problems when finishing copper strip: the coil needs to be removed from the winding machine and the copper strip tail needs to be fixed with cable ties. However, since the springback of high yield strength ratio (≥0.9) tin phosphor bronze strip is 2-3% after cold rolling, the interlayer gap increases due to material springback after the coil is depressurized. After the coil is removed, the copper strip becomes loose between layers and cannot be directly transferred to the next process, affecting production continuity and efficiency.

[0004] Therefore, how to prevent the copper strip from becoming loose after the reel is unloaded from the winding machine is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one embodiment of a high yield strength ratio, high elasticity tin-phosphor bronze strip cold rolling coil to solve the technical problem of loose channels after the coil is unloaded from the winding machine.

[0007] In a first aspect, embodiments of this disclosure provide a coil for cold rolling high yield strength ratio and high elasticity tin-phosphor bronze strip, comprising: a drum adapted for winding tin-phosphor bronze strip, with a left stop plate and a right stop plate disposed on both sides of the drum; a pressing member disposed at the edge of the left stop plate; and a locking position disposed at the edge of the right stop plate; wherein, when locking, the pressing member spans across the drum to cooperate with the locking position, pressing and locking the end of the outermost tin-phosphor bronze strip.

[0008] In a preferred embodiment, the locking position includes a right notch formed on the right baffle, and locking grooves are formed on both sides of the right notch.

[0009] In a preferred embodiment, the pressing member includes a plate body rotatably connected to the left notch of the left baffle, the pressing surface of the plate body having a flexible strip adapted to press the tin-phosphor bronze strip; wherein the plate body is adapted to be flipped, and its end is adapted to extend into the right notch.

[0010] In a preferred embodiment, one end of the plate is provided with a through hole, and a pair of slidable locking blocks are provided inside the hole. The two locking blocks are connected by a spring. When the end of the plate is adapted to be flipped into the right notch, the spring is adapted to drive the locking blocks to extend into the locking groove.

[0011] In a preferred embodiment, a shaped paddle is fixed on the locking block, one end of which passes through a guide hole above the through hole; wherein the shaped paddle moves towards each other along the guide hole to drive the locking block to be pulled out from the limiting groove of the left notch.

[0012] In a preferred embodiment, the locking position includes a right limiting hole, which is formed on the right stop plate.

[0013] In a preferred embodiment, the holding member includes a threaded cylinder rotatably connected to the edge of the left threaded hole of the left baffle, and a threaded rod is screwed into the threaded cylinder; wherein the threaded cylinder is adapted to rotate, causing the threaded rod to move into the right limiting hole, so as to hold the outermost ring of tin-phosphor bronze strip wound on the drum.

[0014] In a preferred embodiment, a stop protrusion is provided in the right limiting hole; and the distance between the stop protrusion and the left stop plate is less than the length of the threaded rod.

[0015] In a preferred embodiment, the threaded rod is made of rubber.

[0016] In a preferred embodiment, the threaded rod has a hardness of 65-80 Shore A.

[0017] The beneficial effect of this utility model is that it provides a coil for cold rolling of high yield strength and high elasticity tin-phosphor bronze strip. By setting a pressing member on the left baffle and a locking position on the right baffle, the pressing member can be rotated to cross the coil and extend into the locking position, thereby pressing the outermost tin-phosphor bronze strip on the coil. This prevents the tin-phosphor bronze strip from becoming loose after the coil is removed from the winding device, thus improving the continuity of tin-phosphor bronze strip production.

[0037] Research has revealed the following drawbacks of existing technologies: Existing coil winding devices have the following problems when finishing copper strip: the coil needs to be removed from the winding machine, and then the copper strip tail needs to be secured with cable ties. However, because the high yield strength ratio (≥0.9) tin-phosphor bronze strip has a springback of 2-3% after cold rolling, the interlayer gap increases due to material springback after the coil is depressurized. After removing the coil, the copper strip becomes loose between layers and cannot be directly transferred to the next process, affecting production continuity and efficiency.

[0038] Therefore, how to prevent the copper strip from becoming loose after the reel is unloaded from the winding machine is a technical problem that urgently needs to be solved in this field.

[0039] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] Example 1

[0043] like Figures 1 to 4 As shown, some embodiments provide a coil for cold rolling high-yield-strength, high-elasticity tin-phosphor bronze strip, comprising: a drum 1, with a left baffle 11 and a right baffle 12 disposed on both sides of the drum 1; the drum 1 is used to mount on a winding or unwinding machine; the surface of the drum 1 is used to wind tin-phosphor bronze strip 2, and the tin-phosphor bronze strip 2 is wound into a coil and fixed between the left baffle 11 and the right baffle 12; a pressure member 3 is disposed at the edge of the left baffle 11; and a pressure member 3 is disposed at the edge of the right baffle 12. Locking position 4; wherein, when locking, the holding member 3 spans across the drum 1 to cooperate with the locking position 4, squeezing and locking the end of the outermost tin phosphor bronze strip 2. When the tin phosphor bronze strip 2 is wound to the set thickness, the winding stops. In order to prevent the coiled tin phosphor bronze strip 2 from loosening after being removed from the winding device, the outermost tin phosphor bronze strip 2 needs to be fixed at this time. Specifically, the holding member 3 is flipped in the direction F so that it spans across the drum 1 and its tail end extends into the locking position 4 to achieve the effect of pressing the outermost tin phosphor bronze strip 2.

[0044] The composition and structure of the pressing member 3 are described in detail below. The pressing member 3 includes a plate 33a, which is rotatably connected to the left notch 31a of the left baffle 11. The pressing surface of the plate 33a has a flexible strip 34a, which is suitable for pressing the tin phosphor bronze strip 2. The plate 33a is adapted to be flipped, and its end is adapted to extend into the right notch 41a. As the plate 33a is flipped, its pressing surface gradually approaches the outermost tin phosphor bronze strip 2 until it abuts against its surface and generates a pressing force. At this time, the end of the plate 33a extends into the right notch 41a.

[0045] like Figure 1 and Figure 3 As shown, for the plate 33a in a relatively fixed initial state and compressed state, please refer to [the relevant documentation]. Figure 4 A through hole 35a is provided at one end of the plate 33a, and a pair of slidable locking blocks 36a are provided inside the through hole 35a. The two locking blocks 36a are connected by a spring 37a. A T-shaped lever 39a is fixed on the locking block 36a, one end of which passes through a guide hole 38a above the through hole 35a. The T-shaped lever 39a moves towards each other along the guide hole 38a to drive the locking block 36a to be pulled out from the limiting groove 32a of the left notch 31a. The T-shaped lever 39a is easy for the operator to use. When it is necessary to flip the plate 33a, it is only necessary to press the two T-shaped levers 39a towards each other. When the locking block 36a is pulled out from the limiting groove 32a, the plate 33a can be separated from the left notch 31a and then flipped over. After the end of the plate extends into the right notch 41a, the force on the two T-shaped levers 39a is removed. At this time, the spring 37a rebounds, allowing the locking block 36a to extend into the locking groove 42a, thus fixing the plate 33a in the pressed state. Specifically, after the end of the plate 33a is adapted to be flipped into the right notch 41a, the spring 37a is adapted to drive the locking block 36a to extend into the locking groove 42a.

[0046] The locking position 4 includes a right notch 41a, which is opened on the right baffle 12, and locking grooves 42a are opened on both sides of the right notch 41a.

[0047] Example 2

[0048] like Figures 5 to 6As shown, some embodiments provide a coil for cold rolling high yield strength ratio and high elasticity tin-phosphor bronze strip, including: a drum 1, with a left baffle 11 and a right baffle 12 disposed on both sides of the drum 1, the drum 1 being mounted on a winding or unwinding machine, the surface of the drum 1 being used to wind tin-phosphor bronze strip 2, the tin-phosphor bronze strip 2 being wound into a coil and fixed between the left baffle 11 and the right baffle 12, the left baffle 11 and the right baffle 12 being disposed on both sides of the drum 1; a pressing member 3 is disposed at the edge of the left baffle 11; and a pressing member 3 is disposed at the edge of the right baffle 12. A locking position 4 is provided; when locking, the pressing member 3 spans across the drum 1 to cooperate with the locking position 4, pressing and locking the end of the outermost tin-phosphor bronze strip 2. When the tin-phosphor bronze strip 2 is wound to the set thickness, the winding stops. In order to prevent the coiled tin-phosphor bronze strip 2 from loosening after being removed from the winding device, the outermost tin-phosphor bronze strip 2 needs to be fixed at this time. Specifically, the pressing member 3 is rotated so that it spans across the drum 1 and its tail end extends into the locking position 4 to achieve the effect of pressing the outermost tin-phosphor bronze strip 2.

[0049] The following describes the composition and structure of the clamping component 3. The clamping component 3 includes a threaded cylinder 32b, which is rotatably connected to the edge of the left threaded hole 31b of the left baffle 11. The left baffle 11 is provided with a left threaded hole 31b, and the position of the left threaded hole 31b corresponds to that of the right limiting hole 41b. Specifically, their central axes coincide. A threaded rod 33b is screwed into the threaded cylinder 32b. Figure 5 As shown, in the initial state, the threaded rod 33b is placed inside the threaded cylinder 32b, and the other end extends to the outside of the threaded cylinder 32b. When it is necessary to press the tin phosphor bronze strip 2, rotate the threaded cylinder 32b to move the threaded rod 33b along the central axis of the left threaded hole 31b, that is, to the right limiting hole 41b, until one end of the threaded rod 33b extends into the right limiting hole 41b and abuts against the stop protrusion 42b. At this time, the threaded rod 33b is in a state of spanning the drum 1, and its outer wall is in a state of pressing the outermost tin phosphor bronze strip 2.

[0050] To achieve better holding effect, the threaded rod 33b is made of rubber. The hardness of the threaded rod 33b is 65-80 Shore A. The threaded cylinder 32b is adapted to rotate, so that the threaded rod 33b moves into the right limiting hole 41b to hold the outermost tin-phosphor bronze strip 2 wound on the drum 1.

[0051] The locking position 4 includes a right limiting hole 41b, which is opened on the right baffle 12. A stop protrusion 42b is provided in the right limiting hole 41b. The distance between the stop protrusion 42b and the left baffle 11 is less than the length of the threaded rod 33b.

[0052] In summary, by setting a pressing member 3 on the left baffle 11 and a locking position 4 on the right baffle 12, the pressing member 3 is rotated to span the drum 1 and extend into the locking position 4, thereby pressing the outermost ring of the tin-phosphor bronze strip 2 on the drum 1. This prevents the tin-phosphor bronze strip 2 from becoming loose after the drum 1 is removed from the winding device, thus improving the production continuity of the tin-phosphor bronze strip 2.

[0053] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
