Technical Field

[0001] The utility model relates to the technical field of wire forming equipment, in particular to a metal wire coiling machine. Background Art

[0002] Some precious metals (usually gold and silver) are used to make jewelry. There are many types of jewelry. In order to maintain its beautiful shape, other metals (such as aluminum alloy) are first used as the base material, and then the surface is covered with precious metals. Finally, other metals are removed to form a hollow structure. In order to keep the aluminum alloy in good performance during use, after being processed into a specific size, it needs to be heat treated before further processing. Aluminum alloy wire is relatively hard and is not easy to be rolled into a certain volume size.

[0003] In the prior art, there is a patent application document with publication number CN202461222U and the name of which is a wheel rim rolling machine. In this document, a rolling mechanism composed of three rollers is provided to realize the bundle forming of the wire. The device is generally only applicable to bundles of one size, and the diameter of the bundle and the pressure on the wire cannot be adjusted, so it is not very practical. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a metal wire rolling machine, which can roll a certain length of wire into a predetermined shape by setting a wire conveying mechanism, a wire bending mechanism and a wire rolling mechanism, thereby improving work efficiency, being suitable for various types of wires, and improving practicality.

[0005] In order to achieve the above-mentioned object, the utility model provides a metal wire coiling machine, characterized in that it comprises a support plate perpendicular to the horizontal plane, and along the moving direction of the wire, the support plate is provided with a wire conveying mechanism, a wire bending mechanism and a wire coiling mechanism;

[0006] The wire conveying mechanism includes a plurality of groups of matching lower driving wheels and upper auxiliary pressing wheels, a slot for the wire to pass through is provided between the lower driving wheels and the upper auxiliary pressing wheels, and a pressure regulating device for regulating the upper auxiliary pressing wheel is provided between each upper auxiliary pressing wheel and the support plate;

[0007] The bending mechanism comprises a guide wheel, a guide plate and a guide lever, wherein the guide plate and the guide lever are both located at the lower part of the guide wheel and guide the wire to the direction of the wire winding mechanism;

[0008] The wire coiling mechanism comprises a main rotating frame and an auxiliary supporting frame. The main rotating frame is rotatably mounted on the supporting plate. The auxiliary supporting frame is sleeved in the rotating bracket and fixed to the main rotating frame by threaded fasteners.

[0009] Preferably, the power sources of the wire conveying mechanism, the wire bending mechanism and the wire bundling mechanism are all the same motor, and the wire conveying mechanism, the wire bending mechanism and the wire bundling mechanism are respectively connected to the motor via mutually meshing reduction gears.

[0010] Preferably, the pressure regulating device is an adjusting block and a rotating adjusting screw connected to the adjusting block, the adjusting block slides in the cavity of the support plate, and a rotating handle is fixedly provided on the top of the rotating adjusting screw.

[0011] Preferably, an arc-shaped guide plate is further provided on one side of the guide plate, and the arc-shaped guide plate is close to the outer side of the auxiliary support frame.

[0012] Preferably, the number of the auxiliary support frames is four, and every two auxiliary support frames are vertically symmetrically installed on the main rotating frame.

[0013] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0014] 1. Since the wire conveying mechanism, wire bending mechanism and wire bundling mechanism are sequentially arranged along the moving direction of the wire, the gap between the upper auxiliary pressure wheel and the lower driving wheel is changed and adjusted by the rotating adjusting screw, and then the pressure on the wire is adjusted, so that the wire can be better shaped when passing through multiple upper auxiliary pressure wheels and lower driving wheels to meet the set requirements. After the size reaches the predetermined value, it will finally be rolled and formed by the main rotating frame and the auxiliary support frame. Since the main rotating frame and the auxiliary support frame are socketed, the position of the auxiliary support frame can be adjusted, and it can be appropriately adjusted according to the hardness of the wire and the size of the arc.

[0015] 2. Since the power of the wire conveying mechanism, wire bending mechanism and the current winding structure all comes from the same motor, the power is transmitted through the meshing of multiple gears as a reduction mechanism, which can effectively reduce the occupied volume of the equipment and reduce maintenance costs.

[0023] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figure 1-Figure 3 The utility model provides a metal wire coiling machine, including a support plate 1 perpendicular to the horizontal plane. Along the moving direction of the wire, the support plate 1 is provided with a wire conveying mechanism 2, a wire bending mechanism 3 and a wire coiling mechanism 4; the support plate 1 is mainly used for support, and cooperates with the support seat below to place heavy equipment such as a motor 11, generally to achieve the shaping and coiling of the wire in a horizontal plane. In actual use, since the motor 11 drives multiple lower driving wheels 21 to provide power for the movement of the wire, and the wire is relatively hard, the wire coiling mechanism 4 generally requires less power and only needs to control the rotation at a certain speed. In the figure, the power of the motor 11 is transmitted sequentially through multi-stage gears, and multiple mechanisms can directly use one motor 11.

[0025] The wire conveying mechanism 2 includes several groups of matching lower driving wheels 21 and upper auxiliary pressure wheels 22. A slot for the wire to pass through is provided between the lower driving wheel 21 and the upper auxiliary pressure wheels 22. A pressure adjustment device for adjusting the upper auxiliary pressure wheel 22 is provided between each upper auxiliary pressure wheel 22 and the support plate 1. A groove is provided between the upper auxiliary pressure wheel 22 and the lower driving wheel 21. The groove is mainly used to limit the wire. The cooperation of multiple upper auxiliary pressure wheels 22 and the lower driving wheel 21 can ensure that the wire is smoother and there is almost no bending.

[0026] The bending mechanism includes a guide wheel 31, a guide plate 32 and a guide lever 33. The guide plate 32 and the guide lever 33 are both located at the lower part of the guide wheel 31 and guide the wire to the direction of the wire winding mechanism 4. The guide wheel 31 and the guide plate 32 guide the wire after being arranged to the outer circumference of the auxiliary support frame 42, and adjust the length of the corresponding auxiliary support frame 42 according to the diameter of the winding bundle as needed. The length and position of the guide plate 32 and the guide lever 33 are adjustable. After the adjustment is completed, they are fixed by rotating the nut. In actual use, the length of the wire bundled each time is generally fixed, so generally no additional cutting equipment is required.

[0027] The wire coiling mechanism 4 includes a main rotating frame 41 and an auxiliary support frame 42. The main rotating frame 41 is rotatably mounted on the support plate 1, and the auxiliary support frame 42 is sleeved in the rotating frame and fixed to the main rotating frame 41 by threaded fasteners.

[0028] The power sources of the wire conveying mechanism 2, the wire bending mechanism 3 and the wire bundling mechanism 4 of the utility model are all the same motor 11, and the wire conveying mechanism 2, the wire bending mechanism 3 and the wire bundling mechanism 4 are respectively connected to the motor 11 through mutually meshing reduction gears.

[0029] The pressure regulating device of the utility model comprises an adjusting block and a rotating adjusting screw 12 connected to the adjusting block. The adjusting block slides in the cavity of the support plate 1, and a rotating handle is fixed on the top of the rotating adjusting screw 12. The rotating handle is used to adjust the position of the adjusting block. A bearing seat is provided in the middle of the adjusting block for placing the upper auxiliary pressing wheel 22. By changing the position of the adjusting block, the gap distance between the upper auxiliary pressing wheel 22 and the lower driving wheel 21 is adjusted, thereby adjusting the pressure on the wire.

[0030] The guide plate 32 of the present invention is also provided with an arc-shaped guide plate on one side, and the arc-shaped guide plate is close to the outer side of the auxiliary support frame 42. The arc-shaped guide plate 32 mainly plays a guiding role.

[0031] The number of the auxiliary support frames 42 of the utility model is four, and every two auxiliary support frames 42 are vertically symmetrically installed on the main rotating frame 41. The auxiliary support frames 42 and the main rotating frame 41 are processed separately, and symmetrical installation is more convenient. When adjusting, the two auxiliary support frames 42 are generally adjusted symmetrically each time to keep their lengths consistent. In this way, the overall roll bundle will be flatter and less prone to bending. Moreover, when rotating in this way, the main rotating frame 41 hardly requires too much power and can rotate under the push of the wire. Generally, the wire made of metal is relatively hard, and is generally spiral after winding, and will not be stacked.

[0032] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
