Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a straightening device for steel core aluminum stranded wire. Background Art

[0002] Aluminum stranded wire is a bare conductor. Aluminum stranded wire generally uses aluminum-clad steel stranded wire as the conductor. The steel core mainly serves to increase the strength, and the aluminum stranded wire mainly serves to transmit electrical energy. A zinc layer is coated on the outermost side of the steel core aluminum stranded wire to prevent oxidation of the internal core wire. During the production process of aluminum stranded wire, in order to detect the galvanized layer and store the aluminum stranded wire, the finished aluminum stranded wire is often wound into a tube. However, when the aluminum stranded wire is used, the aluminum stranded wire wound into a tube needs to be straightened, so a straightening machine is required.

[0003] During use, the existing straightening machine mainly passes the aluminum stranded wire through the wire inlet, straightening wheel and wire outlet in sequence, and then sets a movable clamp at the wire outlet to clamp the aluminum stranded wire, and then pulls the aluminum stranded wire to cause the aluminum stranded wire to be straightened by the straightening wheel. In the above process, since the aluminum stranded wire is woven from multiple strands of aluminum wire, the aluminum stranded wire will be subjected to pressure applied by the straightening wheel during the straightening process, which makes it easy for gaps to form between the multiple strands of aluminum wire on the aluminum stranded wire, thereby affecting the strength of the aluminum stranded wire. Secondly, there will still be residual stress inside the aluminum stranded wire after straightening, which will cause the straightened aluminum stranded wire to bend under the influence of stress, thereby affecting the straightening effect of the aluminum stranded wire. Utility Model Content

[0004] In response to the shortcomings of existing straightening machines, the utility model provides a straightening device for steel-core aluminum stranded wire, which has the advantages of preventing the aluminum stranded wire from forming gaps due to the pressure applied by the straightening wheel after straightening, and using heating to release the internal stress of the aluminum stranded wire, thereby improving the straightening effect. It solves the technical problems such as the formation of gaps in the aluminum stranded wire due to the pressure applied by the straightening wheel during the straightening process.

[0005] The utility model provides the following technical solution: a straightening device for steel core aluminum stranded wire, comprising a straightening box and further comprising:

[0006] A wire inlet is provided in the middle of the left side wall of the straightening box, and a wire outlet is provided in the middle of the right side wall of the straightening box;

[0007] A fixed plate is fixedly mounted on the middle part of the side wall of the inner cavity of the straightening box. A rotating shaft is rotatably mounted on the fixed plate, and a straightening wheel is fixedly sleeved on the outer surface of the rotating shaft.

[0008] Preferably, the outlet includes:

[0009] A sleeve is rotatably sleeved on the inner side wall of the outlet;

[0010] An annular ball groove is provided on the outlet and the sleeve;

[0011] The ball is movably placed in the annular ball groove.

[0012] Preferably, the sleeve includes:

[0013] a spring fixedly connected to the middle portion of the inner side wall of the sleeve;

[0014] The guide block is fixedly connected to the end of the spring away from the sleeve.

[0015] Preferably, the guide block includes:

[0016] An arc-shaped groove is provided on the guide block;

[0017] The heating plate is fixedly connected to the side surface of the ball facing the middle of the sleeve.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By designing the sleeve, annular ball groove, ball guide block and arc groove, when the aluminum stranded wire is straightened and goes out through the outlet, the potential energy of the spring causes the guide block to fit onto the aluminum stranded wire, and then the arc groove on the guide block causes the guide block to be clamped on the multiple aluminum wires on the aluminum stranded wire. At this time, when the aluminum stranded wire moves under the action of tension, the tension exerted on the aluminum stranded wire will be transmitted to the sleeve through the guide block and the spring, causing the sleeve to rotate in the annular ball groove with the ball, thereby utilizing the rotation of the sleeve to cause the gap opened by the straightening wheel to be tightened again, thereby improving the strength of the aluminum stranded wire.

[0020] 2. By designing the guide block and heating plate, the aluminum stranded wire will be discharged through the sleeve after straightening, and the aluminum stranded wire will fit with the guide block inside the sleeve. At this time, the heating plate is turned on to heat the straightened aluminum stranded wire. The heating is then used to release the stress of the aluminum stranded wire, so that the aluminum stranded wire will not bend due to stress after straightening, thereby reducing the influence of stress on the aluminum stranded wire as much as possible and improving the straightening effect of the aluminum stranded wire.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1-4 A straightening device for steel-core aluminum stranded wire comprises a straightening box 1, a wire inlet 2 is provided in the middle of the left side wall of the straightening box 1, a wire outlet 3 is provided in the middle of the right side wall of the straightening box 1, a fixing plate 4 is fixedly installed in the middle of the side wall of the inner cavity of the straightening box 1, a rotating shaft 5 is rotatably installed on the fixing plate 4, and a straightening wheel 6 is fixedly sleeved on the outer surface of the rotating shaft 5 to ensure that after the steel-core aluminum stranded wire enters the straightening box 1 through the wire inlet 2, the steel-core aluminum stranded wire will pass through the straightening wheel 6, and the steel-core aluminum stranded wire will be squeezed and straightened by the straightening wheel 6, and the straightened steel-core aluminum stranded wire will be discharged through the wire outlet 3.

[0028] See also Figures 1-4 A sleeve 31 is rotatably sleeved on the inner side wall of the outlet 3, and an annular ball groove 32 is provided on both the outlet 3 and the sleeve 31. A ball 33 is movably placed in the annular ball groove 32, so that the sleeve 31 can rotate at the outlet 3 through the fit between the ball 33 and the annular ball groove 32.

[0029] See also Figures 1-4 A spring 34 is fixedly welded to the middle of the inner wall of the sleeve 31, and a guide block 35 is fixedly welded to the end of the spring 34 away from the sleeve 31. The spring 34 can be used to force the guide block 35 to always fit on the outer surface of the steel-core aluminum stranded wire, so that the tension exerted on the steel-core aluminum stranded wire will be transmitted to the sleeve 31 through the guide block 35 and the spring 34, causing the sleeve 31 to rotate.

[0030] See also Figures 1-4 An arc groove 36 is provided on the guide block 35 to ensure that the multiple strands of aluminum stranded wire on the steel core wire can fit on the arc groove 36, and the steel core aluminum stranded wire will be stuck in the arc groove 36. A heating plate 37 is fixedly connected to the side of the ball 33 facing the middle of the sleeve 31. The heating plate 37 can be used to heat the steel core aluminum stranded wire, thereby releasing the stress inside the steel core aluminum stranded wire and preventing the steel core aluminum stranded wire from bending due to stress after straightening.

[0031] Working principle: When the steel core aluminum stranded wire needs to be straightened, the aluminum stranded wire is placed into the straightening box 1 through the wire inlet 2, and then the aluminum stranded wire will pass through the straightening wheel 6 in sequence, and finally the straightened aluminum stranded wire will be discharged through the wire outlet 3. In this process, since the aluminum stranded wire is straightened and goes out through the wire outlet 3, the potential energy of the spring 34 causes the guide block 35 to fit on the aluminum stranded wire, and then the arc groove 36 on the guide block 35 is used to cause the guide block 35 to be stuck on the multiple aluminum wires on the aluminum stranded wire. At this time, when the aluminum stranded wire moves under the action of tension, the tension on the aluminum stranded wire will be transmitted to the sleeve 31 through the guide block 35 and the spring 34, so that The sleeve 31 cooperates with the ball 33 to rotate in the annular ball groove 32, so that the rotation of the sleeve 31 can cause the gap of the aluminum stranded wire pressed open by the straightening wheel 6 to be tightened again, thereby improving the strength of the aluminum stranded wire. Secondly, since the aluminum stranded wire will be discharged through the sleeve 31 after straightening, and the aluminum stranded wire will fit with the guide block 35 inside the sleeve 31, the heating plate 37 is turned on at this time, so that the heating plate 37 will heat the straightened aluminum stranded wire, and then use the heating to cause the aluminum stranded wire to release stress, so that the aluminum stranded wire will not bend due to stress after straightening, and the influence of stress on the aluminum stranded wire is reduced as much as possible, thereby improving the straightening effect of the aluminum stranded wire.
