Description

Technical Field

[0001] The utility model relates to the technical field of wire flattening equipment, in particular to a copper wire flattening positioning and adjustable device. Background Technique

[0002] Copper wire refers to the wire produced by pressing or drawing copper. Copper wire is widely used in various fields and can be used to manufacture wires, cables, electric brushes, or for compasses, aviation instruments, etc. Due to its good plasticity, copper wire is also very easy to process by hot pressing and cold pressing.

[0003] Copper wire can be divided into round copper wire, flat wire, shaped wire, etc. according to the cross-sectional shape. Among them, the production process of flat wire is to flatten round copper wire into copper wire with a square cross-sectional shape. The existing copper wire flattening device includes a support, an upper pressing wheel, a lower pressing wheel, an incoming wire guiding wheel, an outgoing wire guiding wheel, and a driving motor capable of driving the lower pressing wheel to rotate. The driving motor is installed on the support, and the upper pressing wheel, the lower pressing wheel, the incoming wire guiding wheel, and the outgoing wire guiding wheel are all rotatably installed on the support. The upper pressing wheel is located above the lower pressing wheel, and the wheel surface of the upper pressing wheel is pressed against the wheel surface of the lower pressing wheel. The incoming wire guiding wheel is located on one side between the upper pressing wheel and the lower pressing wheel, and the outgoing wire guiding wheel is located on the other side between the upper pressing wheel and the lower pressing wheel. Among them, the position of the upper pressing wheel relative to the lower pressing wheel is fixed, which may lead to uneven pressure distribution during the flattening process, affecting the quality consistency of copper wire, and it is impossible to adjust the flattening pressure and gap according to the changes of parameters such as the hardness and diameter of copper wire. This kind of copper wire flattening device can only produce copper wire with a specific diameter size and is difficult to meet the production requirements of different sizes of flat wire. Content of the Utility Model

[0004] The problem to be solved by the utility model is to provide a copper wire flattening positioning and adjustable device, which can finely adjust the position of the upper pressing wheel relative to the lower pressing wheel to meet the production requirements of different sizes of flat wire.

[0005] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0006] A copper wire flattening and positioning adjustable device, comprising a support, an upper pressing wheel, a lower pressing wheel, an incoming wire guiding wheel, an outgoing wire guiding wheel, and a driving motor capable of driving the lower pressing wheel to rotate. The driving motor is installed on the support. The lower pressing wheel, the incoming wire guiding wheel, and the outgoing wire guiding wheel are all rotatably installed on the support. The upper pressing wheel is arranged above the lower pressing wheel, and the wheel surface of the upper pressing wheel is pressed against the wheel surface of the lower pressing wheel. The incoming wire guiding wheel is on one side between the upper pressing wheel and the lower pressing wheel, and the outgoing wire guiding wheel is on the other side between the upper pressing wheel and the lower pressing wheel. It is characterized in that: it further includes a bearing seat; a guiding cavity capable of accommodating the bearing seat is provided on the support, the guiding cavity is above the lower pressing wheel, a gap for the bearing seat to move left and right is provided in the guiding cavity, a guiding strip-shaped through hole is provided on the first side wall of the guiding cavity, and a position fine-tuning mechanism capable of adjusting the left and right movement of the bearing seat is provided on the second side wall of the guiding cavity adjacent to the first side wall; the bearing seat is movably installed in the guiding cavity left and right, a wheel shaft corresponding to the guiding strip-shaped through hole is provided on the bearing seat, one end of the wheel shaft passes through the guiding strip-shaped through hole and exposes outside the guiding strip-shaped through hole, and the upper pressing wheel is installed on one end of the wheel shaft; the power output end of the position fine-tuning mechanism is connected to the outer wall of the bearing seat.

[0007] Before wire pressing, the position fine-tuning mechanism drives the bearing seat to move slightly left and right in the guiding cavity, driving the wheel shaft to also move slightly left and right in the guiding strip-shaped through hole, so that the upper pressing wheel makes a synchronous displacement in the left and right directions, finely adjusting the position of the upper pressing wheel relative to the lower pressing wheel, and precisely adjusting the pressing gap between the upper pressing wheel and the lower pressing wheel.

[0008] When wire pressing, the round copper wire is first introduced between the upper pressing wheel and the lower pressing wheel through the incoming wire guiding wheel, and then the driving motor drives the lower pressing wheel to rotate. The round copper wire feeds under the action of friction, so that the round copper wire is gradually flattened under the extrusion of the upper pressing wheel and the lower pressing wheel, and finally the flat wire is led out by the outgoing wire guiding wheel.

[0009] In a preferred solution, the position fine-tuning mechanism includes a screw rod, a nut, a ball bearing, and a hand wheel. A positioning through hole running left and right is provided on the second side wall of the guiding cavity, the positioning through hole communicates with the guiding cavity, the nut is fixedly installed on the second side wall of the guiding cavity and corresponds to the positioning through hole, the rod part of the screw rod is in threaded cooperation with the nut and passes through the positioning through hole; a positioning groove is provided on the outer wall of the bearing seat, the ball bearing is installed in the positioning groove, the outer ring of the ball bearing is connected to the groove wall of the positioning groove, the inner ring of the ball bearing is connected to the end of the rod part of the screw rod, and the hand wheel is installed on the head end of the screw rod. By rotating the hand wheel to drive the axial movement of the screw rod, the rotational movement is converted into the linear displacement of the bearing seat through the screw pair, realizing the fine adjustment of the position of the upper pressing wheel relative to the lower pressing wheel.

[0010] In a preferred embodiment, the copper wire flattening and positioning adjustable device further includes a pressing rod. A vertically extending threaded hole is provided on the support. The lower end opening of the threaded hole communicates with the guiding cavity. The pressing rod is provided with an external thread matching the threaded hole, and the pressing rod is in threaded engagement with the threaded hole. The lower end of the pressing rod extends into the guiding cavity and is in contact and cooperation with the top surface of the bearing seat. A handle is provided at the upper end of the pressing rod. By rotating the handle, the pressing rod moves up and down in the threaded hole. By pressing the top surface of the bearing seat with the lower end of the pressing rod, it is difficult for the bearing seat to move, further positioning the position of the upper pressing wheel relative to the lower pressing wheel.

[0011] In a preferred embodiment, a first guide rail is provided on the upper side edge of the bearing seat, and an upper guide rail corresponding to the first guide rail is provided on the upper side edge of the guiding cavity. The length of the upper guide rail is greater than the length of the first guide rail. A first strip-shaped groove with an upward-facing notch is provided on the first guide rail, and an upper strip-shaped groove with a downward-facing notch is provided on the upper guide rail. The upper strip-shaped groove and the first strip-shaped groove are vertically opposite, and a plurality of upper balls are provided between the upper strip-shaped groove and the first strip-shaped groove.

The second strip-shaped groove and the lower strip-shaped groove are vertically opposite, and a plurality of lower balls are provided between the second strip-shaped groove and the lower strip-shaped groove. By providing the upper balls and the lower balls, the movement of the bearing seat is changed from sliding friction to rolling friction, reducing the movement resistance of the bearing seat.

[0012] In a preferred embodiment, the upper pressing wheel includes an upper hub and an upper pressing ring. The upper hub is installed at one end of the wheel shaft. A first annular groove is provided on the circumferential surface of the upper hub, and the upper pressing ring is located in the first annular groove. The circumferential surface of the upper pressing ring is an outwardly convex annular convex surface. The lower pressing wheel includes a lower hub and a lower pressing ring. The lower hub is rotatably installed on the support. A second annular groove is provided on the circumferential surface of the lower hub, and the lower pressing ring is located in the second annular groove. The circumferential surface of the lower pressing ring is an inwardly concave annular concave surface. The annular convex surface is in contact and cooperation with the annular concave surface. Generally, the cross-sectional shape of a traditional flattened copper wire is rectangular, and a copper wire with a rectangular cross-sectional shape may not meet the performance requirements in some specific applications. Furthermore, by designing the upper pressing ring of the upper pressing wheel and the lower pressing ring of the lower pressing wheel to be in concave-convex surface cooperation, the copper wire can be flattened into a flat copper wire with one concave side and one convex side, increasing the different cross-sectional shapes of the flat wire to meet the performance requirements in some specific applications.

[0013] In another preferred embodiment, the upper pressing wheel includes an upper hub and an upper pressing ring. The upper hub is mounted on one end of the wheel axle. A first annular groove is provided on the circumferential surface of the upper hub.

The lower pressing ring is located in the second annular groove, and the circumferential surface of the lower pressing ring is an outwardly protruding annular convex surface. The annular convex surface is in contact and cooperation with the annular concave surface.

[0014] In a further preferred embodiment, the upper pressing ring and the lower pressing ring are made of ceramic. Ceramic materials (such as alumina, silicon nitride, etc.) have extremely high hardness and excellent wear resistance. During the process of flattening the copper wire, the upper pressing ring and the lower pressing ring need to continuously bear the extrusion and friction of the copper wire. The ceramic material can significantly reduce the wear rate of the surfaces of the upper pressing ring and the lower pressing ring, reduce the decrease in dimensional accuracy or surface defects caused by wear, thereby prolong the service life of the upper pressing ring and the lower pressing ring, and reduce the equipment maintenance frequency and cost. At the same time, the ceramic surface can be processed to extremely high smoothness, reducing defects such as scratches and burrs on the surface of the copper wire, improving the surface quality of the product, and meeting the requirements of high-precision applications.

[0027] Before wire pressing, the position fine-tuning mechanism 7 is used to drive the bearing seat 6 to move slightly left and right in the guiding cavity 11, driving the wheel shaft 61 to also move slightly left and right in the guiding strip-shaped through hole 13, so that the upper pressing wheel 2 makes a synchronous displacement in the left and right directions, finely adjusting the position of the upper pressing wheel 2 relative to the lower pressing wheel 3, and precisely adjusting the pressing gap 12 between the upper pressing wheel 2 and the lower pressing wheel 3.

[0028] During wire pressing, the round copper wire is first introduced between the upper pressing wheel 2 and the lower pressing wheel 3 through the incoming wire guiding wheel 4, and then the driving motor drives the lower pressing wheel 3 to rotate.

By rotating the handwheel 74 to drive the axial movement of the screw rod 71, the rotational movement is converted into a linear displacement of the bearing seat 6 through a screw pair, realizing the fine-tuning of the position of the upper pressing wheel 2 relative to the lower pressing wheel 3.

[0030] This copper wire flattening and positioning adjustable device further includes a pressing rod 8. A screw hole 15 running up and down is provided on the support 1.

The annular convex surface 221 is in contact and cooperation with the annular concave surface 321. Usually, the cross-sectional shape of traditional copper wire after being flattened is rectangular. Copper wire with a rectangular cross-sectional shape may not meet the performance requirements in some specific applications. Furthermore, by designing the upper pressing ring 22 of the upper pressing wheel 2 and the lower pressing ring 32 of the lower pressing wheel 3 to be in concave-convex surface cooperation, the copper wire can be flattened into a flat copper wire with one concave side and one convex side, which can increase the different cross-sectional shapes of the flat wire to meet the performance requirements in some specific applications.

[0033] The materials of the upper pressing ring 22 and the lower pressing ring 32 are ceramics. Ceramic materials (such as alumina, silicon nitride, etc.) have extremely high hardness and excellent wear resistance. During the process of flattening the copper wire, the upper pressing ring 22 and the lower pressing ring 32 need to continuously bear the extrusion and friction of the copper wire. The ceramic material can significantly reduce the wear rate of the surfaces of the upper pressing ring 22 and the lower pressing ring 32, reduce the decrease in dimensional accuracy or surface defects caused by wear, thereby prolong the service life of the upper pressing ring 22 and the lower pressing ring 32, and reduce the equipment maintenance frequency and cost. At the same time, the ceramic surface can be processed to extremely high smoothness, reducing defects such as scratches and burrs on the surface of the copper wire, improving the surface quality of the product, and meeting the requirements of high-precision applications.
