DETAILED DESCRIPTION

[0020] The technical scheme of the utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] For example, Figures 1 to 4As shown, a kind of wire guiding device of steel wire, including base 1, for example, base 1 can be supported in the front end of wire drawing machine, and two groups of guide wheels 2 are symmetrically arranged on base 1, and the steel wire 18 entering wire drawing machine is clamped and guided by two groups of guide wheels 2.

[0022] Each guide wheel 2 can include connecting shaft and coaxially arranged first wheel body 3 on connecting shaft, second wheel body 4. Two wheel bodies are spaced apart in axial direction, so that two wheel bodies cooperate to provide the clamping of steel wire 18. Specifically, the opposite side walls of the two wheel bodies are each configured with an annular slope 5, the inclination directions of the two slopes are opposite, and a guide groove 6 is formed, which gradually flares outward in the radial direction. Therefore, the two guide grooves 6 of the corresponding two guide wheels 2 cooperate to form stable clamping and guiding of the steel wire 18 passing through the middle.

[0023] And the first wheel body 3 is also adapted to change the installation height in the axial direction, so that the distance with the second wheel body 4 can be changed, and the width of the guide groove 6 can be changed. It can be understood that when the width of the guide groove 6 changes, the clamping area for the steel wire 18 to be clamped between the two guide grooves 6 will also increase accordingly. Specifically, the following use process can be had:

[0024] Put the steel wire 18 into the clamping area, then adjust the first wheel body 3 to be close to the second wheel body 4, so that the two annular slopes 5 of the guide groove 6 abut against the two sides of the steel wire 18 to realize clamping. And when the steel wire 18 is put into the clamping area, the steel wire 18 will be automatically centered under the guidance of the two lateral slopes.

[0025] In some embodiments, the first wheel body 3 can be fixed to the connecting shaft by screwing, for example, a thread can be provided on the connecting shaft for screwing of the first wheel body 3, so as to change the distance between the first wheel body 3 and the second wheel body 4. Alternatively, the first wheel body 3 can be sleeved on the connecting shaft, and the screw cap on the connecting shaft is tightened to abut against the steel wire 18.

[0026] For example, a rotating table (not shown) can also be provided on the base 1, which can be driven to rotate by a motor or can only provide a rotating degree of freedom without a driving source. The connecting shaft is arranged at the center of the rotating table, and the steel wire 18 can be guided more effectively by rotating.

[0027] In addition, the utility model also is adapted to set up the push rod 7 that can move along the radial direction on the top surface of second wheel body 4, and the end of push rod 7 still is provided with clamping plate 8. Drive mechanism 9 is also connected on push rod 7, and push rod 7 can be driven to push out outward in the process of first wheel body 3 descending by drive mechanism 9, until clamping plate 8 realizes the lateral clamping of steel wire 18. Clamping plate 8 can realize auxiliary clamping of steel wire 18 in the lateral vacancy inside guide groove 6, and the guided movement of steel wire 18 is more stable and reliable.

[0028] As Figure 2 shown, in a specific example, the driving mechanism 9 can be an electric cylinder 10, for example, an infrared distance measuring device (not shown) can be arranged between the two wheel bodies, as the measured value gradually decreases, the electric cylinder 10 pushes out the push rod 7 according to the proportional relationship of the expected distance, until the clamping plate 8 realizes the lateral abutment clamping of the steel wire 18.

[0029] As Figure 3 shown, in other examples, the driving mechanism 9 can also include a first inclined surface 11 arranged on the end of the push rod 7, and a driving block 12 arranged on the bottom surface of the first wheel body 3, and a second inclined surface 13 arranged on the driving block 12. It Figure 3 can be seen that the first inclined surface 11 and the second inclined surface 13 have a matching slope, during the process that the first wheel body 3 approaches the second wheel body 4, the second inclined surface 13 will push the first inclined surface 11, and drive the push rod 7 to be pushed out. More preferably, in this example, a return spring 14 can be arranged on the push rod 7, to reset the push rod 7 to the initial position when the first wheel body 3 is axially reset away from the second wheel body 4.

[0030] As Figure 4 provided in another example, the driving mechanism 9 can include a gas cylinder 15, and a gas bag 16 arranged on the top surface of the second wheel body 4, which is in communication with the gas cylinder 15 through a pipeline. During the process that the first wheel body 3 approaches the second wheel body 4, the first wheel body 3 will cause the gas bag 16 to be extruded, and the gas in the gas bag 16 will be filled into the gas cylinder 15, and in this way push the push rod 7 to be pushed out. In addition, the gas bag 16 is also provided with a pressure relief valve 17, which makes the clamping plate 8 abuts against the steel wire 18, and the first wheel body 3 can still continue to approach the second wheel body 4 to realize the overall clamping of the steel wire 18, and the gas in the gas bag 16 can be discharged from the pressure relief valve 17 to meet the freedom of movement of the first wheel body 3.

[0031] The above is only the preferred embodiment of the present application, it should be understood that the present application is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be within the scope of the concept described herein, by the above teaching or related art or knowledge. The changes made by the person skilled in the art without departing from the spirit and scope of the present application, shall be within the scope of protection of the appended claims of the present application.
