[0002] With the development of electronic telecommunications in the world, the demand for copper wires in the wire and cable, enameled wire and electronic wire industries has increased rapidly, which has led to an increasing demand for copper wire rods. Wire drawing is a metal processing technology. In metal pressure processing, the metal cross-sectional area is compressed by the die under the action of external force to obtain the required cross-sectional area shape and size.

[0003] Before drawing the copper rod, it is necessary to place the copper rod on a supporting device. In the prior art, the spacing between multiple limit rods is generally adjusted by screwing multiple bolts one by one so that the limit rods can fix the copper rod. The steps are relatively cumbersome and not conducive to improving work efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a copper rod wire drawing support device.

[0007] A fixing frame is arranged below the support plate, and a positioning mechanism is arranged below the support plate at a position close to the fixing frame. A cross bar is connected between the two fixing frames, and both ends of the fixing frames are rotatably connected with moving wheels.

[0008] Preferably, the retracting and releasing mechanism comprises a rotating shaft and a second round rod, the rotating shaft is rotatably connected to the support plate, a turntable is fixed to the upper end of the rotating shaft, and a driven gear is fixed to the lower end of the rotating shaft, one side of the driven gear is meshedly connected with a driving gear, the driving gear is rotatably connected to the support plate via a connecting shaft, a rotating handle is fixedly connected to the lower end of the connecting shaft, a first round rod is fixed above the turntable, the second round rod is fixedly connected to the first limit rod, and a connecting rod is rotatably connected between the second round rod and the first round rod, and a limit block is fixed below the second round rod.

[0009] Preferably, a sliding groove is provided above the support plate at a position corresponding to the limiting block, and the limiting block is in a square structure.

[0010] Preferably, protrusions are symmetrically arranged on the inner side of the first limiting rod, and grooves are provided on both sides of the second limiting rod at positions corresponding to the protrusions.

[0011] Preferably, a plurality of the second limiting rods are connected with telescopic rods.

[0012] Preferably, damping patterns are evenly arranged on the edge of the turntable, and an inner concave portion is provided above the support plate at a position corresponding to the turntable.

[0013] Preferably, outer sides of the first limiting rod and the second limiting rod are both in an arc surface structure.

[0014] Preferably, the positioning mechanism includes a fixing member and a first magnet, the fixing member and the first magnet are fixedly connected to the support plate, a back plate is arranged between every two fixing members, the back plate is rotatably connected to the fixing member through a pin shaft, and a second magnet is fixed above one side of the back plate, a torsion spring is sleeved on the surface of the pin shaft between the fixing member and the back plate, a fixing block is fixed to one side of the back plate, and a foot pedal is fixed to one end of the fixing block.

[0016] Preferably, the surface of the foot pedal is provided with anti-slip textures.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up the retracting and releasing mechanism, multiple first limit rods can be quickly and synchronously expanded outward without much operation, until multiple groups of first limit rods and second limit rods are pressed against the inner side of the copper rod. After the copper rod is fixed, the copper rod will not shift during the process of pushing the support device and drawing the wire;

[0019] 2. By setting a sliding connection between the second limit rod and the first limit rod, after continuous wire drawing, the length of the copper rod is reduced, that is, the overall height of the copper rod is reduced.

When the second magnet and the first magnet are attracted to each other, the support plate can be temporarily fixed to prevent the bottom end of the support plate from contacting the ground, thereby smoothly moving the support device. When the second magnet is not attracted to the first magnet, the bottom end of the support plate can be pressed against the ground under the elastic force of the torsion spring, thereby positioning the support device and preventing accidental sliding.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7 A copper rod wire drawing support device comprises a support plate 1, a first limiting rod 8 is arranged above the support plate 1, and the support plate 1 is connected to the first limiting rod 8 through a retracting mechanism, a second limiting rod 13 is slidably connected inside the first limiting rod 8, and a spring 14 is connected between the first limiting rod 8 and the second limiting rod 13, and the retracting mechanism is used to limit the copper rod;

[0031] A fixing frame 18 is provided below the support plate 1, and a positioning mechanism is provided below the support plate 1 near the fixing frame 18, a cross bar 19 is connected between the two fixing frames 18, and both ends of the fixing frames 18 are rotatably connected to moving wheels 20, and the positioning mechanism is used to achieve a stabilizing effect on the entire support device.

[0032] The retracting and releasing mechanism includes a rotating shaft 2 and a second round rod 9, the rotating shaft 2 is rotatably connected to the support plate 1, a rotating disk 6 is fixed to the upper end of the rotating shaft 2, and a driven gear 3 is fixed to the lower end of the rotating shaft 2, a driving gear 4 is meshed and connected to one side of the driven gear 3, the driving gear 4 is rotatably connected to the support plate 1 through a connecting shaft 28, a rotating handle 5 is fixedly connected to the lower end of the connecting shaft 28, a first round rod 7 is fixed above the rotating disk 6, the second round rod 9 is fixedly connected to the first limiting rod 8, and a connecting rod 10 is rotatably connected between the second round rod 9 and the first round rod 7, and the first round rod 10 is rotatably connected between the second round rod 9 and the first round rod 7. A limiting block 11 is fixed below the two round rods 9, and a slide groove 12 is provided above the support plate 1 at a position corresponding to the limiting block 11. The limiting block 11 is a square structure. This structure enables the first limiting rod 8 to move only along the trajectory of the slide groove 12. By setting a retracting and releasing mechanism, multiple first limiting rods 8 can be quickly and synchronously expanded outward without excessive operation, until multiple groups of first limiting rods 8 and second limiting rods 13 are pressed against the inner side of the copper rod. After the copper rod is fixed, the copper rod will not shift during the process of pushing the support device and drawing the wire.

[0033] Bumps 15 are symmetrically arranged on the inner side of the first limiting rod 8, and grooves 16 are opened on both sides of the second limiting rod 13 at the positions corresponding to the bumps 15. The cooperation between the bumps 15 and the grooves 16 limits the second limiting rod 13, so that the second limiting rod 13 can only slide up and down inside the first limiting rod 8.

[0034] Telescopic rods 17 are connected between the plurality of second limiting rods 13 . The provision of the telescopic rods 17 facilitates the simultaneous pulling of the plurality of second limiting rods 13 upwards and does not hinder the outward expansion of the plurality of second limiting rods 13 .

[0035] The edge of the turntable 6 is evenly provided with damping patterns, and an inner concave portion is provided above the support plate 1 at a position corresponding to the turntable 6 . The damping patterns can enhance the friction between the turntable 6 and the inner concave portion, thereby improving the stability of the turntable 6 .

[0036] The outer sides of the first limiting rod 8 and the second limiting rod 13 are both in an arc surface structure, and this structure can make the first limiting rod 8 and the second limiting rod 13 contact the inner side of the copper rod more fully.

[0037] The positioning mechanism includes a fixing member 21 and a first magnet 24, the fixing member 21 and the first magnet 24 are fixedly connected to the support plate 1, a butt plate 22 is arranged between every two fixing members 21, the butt plate 22 is rotatably connected to the fixing member 21 through a pin shaft 23, and a second magnet 25 is fixed on one side of the butt plate 22, the second magnet 25 and the first magnet 24 attract each other with opposite poles, the surface of the pin shaft 23 is located between the fixing member 21 and the butt plate 22 and is sleeved with a torsion spring, a fixing block 26 is fixed on one side of the butt plate 22, a foot pedal 27 is fixed at one end of the fixing block 26, and the surface of the foot pedal 27 is provided with anti-slip patterns, when the second magnet 25 and the first magnet 24 attract each other, the butt plate 22 can be temporarily fixed to prevent the bottom end of the butt plate 22 from contacting the ground, thereby smoothly moving the support device, and when the second magnet 25 is not attracted to the first magnet 24, the elastic force of the torsion spring can make the bottom end of the butt plate 22 close to the ground, so as to position the support device and prevent accidental sliding.

[0038] In the present invention, the copper rod is first placed on the support plate 1, and the copper rod wound in a circle is sleeved on the outside of the plurality of first limit rods 8. The handle 5 is held to rotate the driving gear 4 clockwise, and the driving gear 4 then drives the driven gear 3 to rotate counterclockwise, so that the turntable 6 rotates counterclockwise along with the driven gear 3 (in Figure 5 ), under the rotation of the turntable 6, the first round rod 7 gradually approaches the corresponding slide groove 12, and under the rotation connection of the connecting rod 10, the limit block 11 slides in the slide groove 12 to limit the first limit rod 8, so that multiple first limit rods 8 can be synchronously expanded outward. At the same time, hold any telescopic rod 17 and pull up multiple second limit rods 13 at the same time. At this time, the spring 14 is stretched until multiple groups of first limit rods 8 and second limit rods 13 are pressed against the inner side of the copper rod, and because the second limit rod 13 is pressed against the inner side of the copper rod, after releasing the telescopic rod 17, the second limit rod 13 will not retract temporarily. After the copper rod is fixed, the support device can be pushed to the specified position. During the movement, the copper rod will not shift, and during the wire drawing process, the copper rod will not shift;

[0039] After the support device is moved to the designated position, the foot pedal 27 is lifted upwards, and the second magnet 25 is separated from the first magnet 24 under the positive rotation of the support plate 22. Subsequently, under the elastic force of the torsion spring, the bottom end of the support plate 22 can be pressed against the ground, so as to position the support device and prevent accidental sliding. Before the support device needs to be moved next time, the foot pedal 27 is stepped downwards, and the torsion spring is compressed under the reverse rotation of the support plate 22, so that the second magnet 25 gradually approaches the first magnet 24 until the second magnet 25 and the first magnet 24 are attracted to each other, thereby temporarily fixing the support plate 22 and preventing the bottom end of the support plate 22 from contacting the ground, thereby smoothly moving the support device.

[0040] After continuous wire drawing, the length of the copper rod decreases, that is, the overall height of the copper rod decreases. When the second limit rod 13 cannot contact the inner side of the copper rod, the elastic force of the spring 14 retracts and the second limit rod 13 is reset downward to avoid obstruction to the continuous upward pulling of the copper rod.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
