[0001] The invention belongs to the technical field of aluminum electrolysis, and in particular relates to a column busbar sawing device. Background Art

[0002] At present, the production of aluminum in my country's industry is mainly carried out by the electrolytic aluminum process. In the electrolytic aluminum process, the conductor busbar that transmits electricity to the electrolytic cell is a cast aluminum ingot. Since most of the aluminum ingots entering the site during the processing of the aluminum busbar are long strips, they need to be cut, and some busbars need to be cut at a certain angle.

[0003] The aluminum busbars to be processed are large in size, heavy in weight, and long in length. The sawing machines currently produced in China cannot meet the needs of sawing aluminum busbars at one time. In actual sawing, two sawing devices are generally used. One is to saw the busbars of sufficient length into several short-length column busbars, and then use another sawing device with adjustable angle to bevel the sawed short column busbars, so as to saw out column busbars of a certain angle. This not only requires more sawing equipment and occupies site space, but also reduces the sawing efficiency, resulting in a long sawing cycle, frequent transportation, and time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figures 1 to 17 As shown, a column busbar sawing device includes a first frame 1 and a second frame 4 arranged perpendicular to each other, a sawing mechanism is axially slidably arranged on the first frame 1, and the lateral movement of the sawing mechanism is achieved by a telescopic mechanism. The sawing mechanism includes a first saw blade 83 and a second saw blade 84 arranged on both sides of the first frame 1.

[0040] like Figures 1 to 17 As shown, the bottom end of the first frame 1 is rotatably provided with a third frame 3, and one side of the third frame 3 is provided with a first avoidance cutout 353, and the third frame 3 can be rotated to the side where the first saw blade 83 is located to align with the second frame 4 (as shown in FIG. Figure 3 ), and the first saw blade 83 is arranged opposite to the first avoidance cutout 353 (as shown Figure 4 As shown), at this time, the second frame 4 and the third frame 3 are butt-jointed and located on the same horizontal line. The busbar 5 to be sawed is arranged on the second frame 4 and the third frame 3. The busbar 5 is a long busbar and needs to be sawed in small sections first. In this case, the sawing mechanism can be driven to move horizontally, and the first saw blade 83 can be used to move horizontally to saw the busbar 5 on the second frame 4 and the third frame 3, and the sawed small busbar 51 is placed on the third frame 3.

[0041] like Figures 1 to 17 As shown, an inclined second avoidance cutout 32 is provided in the middle of the third frame 3, and the third frame 3 can be rotated to the side where the second saw blade 84 is located, and the second avoidance cutout 32 is parallel to the first frame 1 and is arranged directly opposite to the second saw blade 84 (as shown in FIG. Fig. 9 , 10 In this case, the small busbar 51 cut by the first saw blade 83 changes position with the rotation of the third frame 3 and is transferred to the other side of the first frame 1, that is, to the side of the second saw blade 84. Then, the sawing mechanism can be driven to move horizontally, and the second saw blade 84 can be used to move horizontally to saw the small busbar 51 on the third frame 3, thereby sawing out the column busbar 5 at a certain angle.

[0042] Reference Figure 3 , Figure 4In the present invention, the length of the third frame 3 is slightly greater than the width of the first frame 1. When the third frame 3 rotates and is aligned with the second frame 4, that is, the third frame 3 and the second frame 4 are arranged in parallel, at this time, the end of the third frame 3 is located on the inner side of the second saw blade 84, that is, the sawing mechanism moves horizontally. When the first sawing mechanism saws the busbar 5, the second saw blade 84 moves and will not interfere with the third frame 3.

[0043] Reference Figure 3 , Figure 4 , Figure 8 and Fig. 9 In the present invention, the third frame 3 rotates only 45 degrees each time; the angle between the second avoidance cutout 32 and the third frame 3 is 45 degrees, and the second avoidance cutout 32 is set in the middle position of the third frame 3, and is centrally symmetrical. With this design, when the third frame 3 rotates 45 degrees so that the second avoidance cutout 32 faces the second saw blade 84, the second saw blade 84 can cut through the center of the second avoidance cutout 32 to divide the small busbar 51 into two column busbars with 45-degree sections. When the second saw blade 84 moves to saw the small busbar 51, the first saw blade 83 moves, but the first saw blade 83 is located between the second frame 4 and the first frame 1, and will not collide with the second frame 4.

[0045] like Figures 14 to 16 As shown, further, a weight reduction groove 34 is provided through the middle of the third frame 3, a recovery groove 35 is provided at the bottom of the weight reduction groove 34, and the second avoidance cutout 32 is provided opposite to the recovery groove 35. When the second saw blade 84 cuts the small section of the busbar 51 on the third frame 3 at a 45-degree angle, the shavings generated by the sawing will fall into the recovery groove 35 for collection.

[0046] like Figure 4 , Figures 14 to 16 As shown, further, a recovery channel 36 connected to the recovery groove 35 is provided on one side of the third frame 3, and the recovery channel 36 is arranged obliquely, and the recovery channel 36 is arranged on the side where the first avoidance cutout 353 is located. When the first saw blade 83 performs a small section sawing on the busbar 5 on the second frame 4 and the third frame 3, the shavings generated by the sawing will fall into the recovery channel 36 and finally reach the recovery groove 35 for collection.

[0047] like Figure 4 , Figures 14 to 16As shown, further, a receiving plate 37 is obliquely arranged on the outer side of the recovery channel 36. When the second frame 4 and the third frame 3 are docked, the end of the receiving plate 37 is arranged close to the side wall of the second frame 4, and the shavings after sawing by the first saw blade 83 can be received by the receiving plate 37 and recycled in the recovery channel 36. A discharge port 351 is arranged on one side of the third frame 3 to discharge the shavings in the recovery groove 35. This recovery structure changes with the position of the third mechanism at any time, and can recover the shavings generated when sawing on both sides. The structure is ingenious and the recovery effect is good.

[0048] Figures 14 to 16 As shown, in the present invention, a positioning groove 31 is provided at the upper end of the third frame 3, the width of the positioning groove 31 is equal to or greater than the width of the busbar 5, and a plurality of threaded holes 33 for installing locking screws are provided on both sides of the positioning groove 31. In this way, the small busbar 51 after sawing can be stably fixed in the positioning groove 31, and then rotated 45 degrees, and then sawed by the second saw blade 84 at 45 degrees.

[0049] In the present invention, a plurality of bottom holes 352 are provided at the bottom end of the third frame 3, and rollers 354 are rotatably provided in the bottom holes 352, and the third frame 3 is supported on the foundation by the rollers 354 to realize the rotational movement of the third frame 3. Of course, an arc-shaped guide rail 6 can also be provided on the foundation, and the rollers 354 can be arranged in the guide rail 6 to rotate along a fixed track.

[0050] In the present invention, only one sawing device is needed to saw a long column busbar 5 into a small section busbar 51 material, and on this basis, by adjusting the angle, the small section material is sawed at a certain angle, and finally a column busbar at a certain angle is produced. The device occupies a small space, has a higher sawing efficiency, further shortens the sawing process and cycle, and saves time and labor.
