Description

Technical Field

[0001] This utility model relates to the technical field of busbar processing equipment, and in particular to a busbar processing machine for a frequency converter production line. Background Technology

[0002] According to the patent document with publication number CN220971414U, the patent document first moves the lower part of the shearing component downward, which in turn drives the second shearing part to move downward to shear the busbar. During this process, the lower end face of the busbar is supported by the support part and the upper end face of the busbar is restricted by the pressing part. Then, the punching part of the punching component moves downward to punch holes in the busbar on the fixing part. Finally, the bending cylinder in the bending component drives the flat bending die to move toward the flat bending punch to achieve bending of the busbar. During this process, the bending shaft contacts the busbar and rolls on the outer end face of the busbar.

[0003] In the process of bending the busbar by moving the flat bending die toward the flat bending punch, the patent document states that different busbars require different bending angles. When the bending angle needs to be changed, it is necessary to replace the flat bending die and flat bending punch with suitable ones, which is troublesome. In addition, when the flat bending die and flat bending punch are close to each other, the busbar is prone to slippage and displacement under force, which affects the bending accuracy.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8 As shown, a busbar processing machine for a frequency converter production line includes a machine base 1 and a bending mechanism 9.

[0029] In this embodiment: the bending mechanism 9 includes a first bending frame 901, which is slidably connected to the top front side of the machine base 1. The first bending frame 901 has a first concave plate 902 and a second concave plate 903 for supporting the bending of the busbar. An adjusting frame 904 is slidably connected inside the first bending frame 901. An adjusting screw 905 is threadedly connected to one side of the first bending frame 901. A first fixing plate 906 located on one side of the adjusting screw 905 is fixed to the top of the machine base 1. The first fixing plate 906 and the first bending frame 904 are connected to the first bending frame 901. Two springs 907 are fixed between the bending frames 901. A second bending frame 908 located on the other side of the first bending frame 901 is slidably connected to the top of the machine base 1. The second bending frame 908 is provided with a first convex plate 909 and a second convex plate 910 for pushing the busbar to bend. A connecting rod 911 is rotatably connected to the rear side of the second convex plate 910. A third cylinder 912 is fixed inside the second bending frame 908. A second fixing plate 913 located on the other side of the second bending frame 908 is fixed to the top of the machine base 1. On the other side, a fourth cylinder 914 is fixed. By rotating the adjusting screw 905, the adjusting frame 904 moves along both sides, thereby moving the first concave plate 902 and the second concave plate 903 to form an angle that meets the bending requirements of the busbar. The fourth cylinder 914 pushes the second bending frame 908 to one side, thereby moving the first convex plate 909 and the second convex plate 910 to one side, so that the first convex plate 909 and the first concave plate 902 clamp the rear side of the busbar, and the second convex plate 910 and the second concave plate 903 hold the busbar in place. The front side of the wire is clamped, and the connecting rod 911 is pushed to one side by the third cylinder 912. Then the connecting rod 911 pushes the first concave plate 902 and the second concave plate 903 to gradually squeeze the busbar. When the included angle of the first convex plate 909 and the second convex plate 910 is the same as the included angle of the first concave plate 902 and the second concave plate 903, the busbar bending is completed. The first convex plate 909 and the second convex plate 910 continue to move to push the first bending frame 901 to move. The two springs 907 contract, and the busbar is continuously squeezed during this process.

[0030] In this embodiment: a pad 2 is fixed on the top rear side of the machine base 1, a support plate 3 is provided on the upper side of the pad 2, the support plate 3 is fixedly connected to the machine base 1, a first cylinder 4 is fixed on the top of the support plate 3, and a shearing blade 5 for cutting the busbar is fixed on the telescopic end of the first cylinder 4. The shearing blade 5 is driven by the first cylinder 4 to move downward to cut the busbar on the pad 2.

[0031] In this embodiment: a pad frame 6 is fixed on the top front side of the machine base 1, a second cylinder 7 is fixed on the top of the pad frame 6, and a punching knife 8 for punching busbars is fixed on the telescopic end of the second cylinder 7. The punching knife 8 is driven to move downward by the second cylinder 7 to punch the busbars on the pad frame 6.

[0032] In this embodiment: one side of the first concave plate 902 and one side of the second concave plate 903 are hinged together. The top and bottom of one side of the first concave plate 902 are both hinged to the adjusting frame 904. One end of the adjusting screw 905 extends into the first bending frame 901 and is rotatably connected to the adjusting frame 904. The adjusting frame 904 is moved by the movement of the adjusting screw 905, which in turn drives one side of the first concave plate 902 and one side of the second concave plate 903 to move along both sides.

[0033] In this embodiment: the other side of the first concave plate 902 and the second concave plate 903 are slidably connected to the first bending frame 901. The other side of the top and the other side of the bottom of the first bending frame 901 are provided with first sliding grooves 10 for cooperating with the first concave plate 902 and the second concave plate 903. By moving one side of the first concave plate 902 and one side of the second concave plate 903 along both sides, the other side of the first concave plate 902 and the second concave plate 903 slide in the first sliding grooves 10, thereby adjusting the bending angle of the first concave plate 902 and the second concave plate 903.

[0034] In this embodiment: the rear side of the first convex plate 909 and the front side of the second convex plate 910 are both slidably connected to the second bending frame 908. The top side and the bottom side of the second bending frame 908 are provided with second sliding grooves 11 for cooperating with the first convex plate 909 and the second convex plate 910. By moving the front side of the first convex plate 909 and the rear side of the second convex plate 910 to one side, the rear side of the first convex plate 909 and the front side of the second convex plate 910 slide in the second sliding groove 11, thereby the first concave plate 902 and the second concave plate 903 gradually squeeze the busbar.

[0035] In this embodiment: the front side of the first convex plate 909 and the rear side of the second convex plate 910 are hinged together; the telescopic end of the third cylinder 912 is fixedly connected to the connecting rod 911; and the telescopic end of the fourth cylinder 914 is fixedly connected to the second bending frame 908. The third cylinder 912 drives the connecting rod 911 to move to one side, thereby pushing the front side of the first convex plate 909 and the rear side of the second convex plate 910 to move to one side.

[0036] Working principle: Place the busbar to be cut on the top of the pad 2. The first cylinder 4 drives the shearing blade 5 to move downward to cut the busbar. Place the busbar to be punched on the pad 6. The second cylinder 7 drives the punching blade 8 to move downward to punch the busbar.

[0037] According to the busbar bending requirements, rotating the adjusting screw 905 drives the adjusting frame 904 to move along both sides, thereby moving one side of the first concave plate 902 and one side of the second concave plate 903 along both sides, so that the other side of the first concave plate 902 and the second concave plate 903 slides in the first slide groove 10, thereby adjusting the bending angle of the first concave plate 902 and the second concave plate 903, placing the busbar to be bent on the other side of the first concave plate 902 and the second concave plate 903, and the fourth cylinder 914 pushes the second bending frame 908 to one side, thereby driving the first convex plate 909 and the second convex plate 910 to one side, so that the first convex plate 909 and the first concave plate 902 clamp the rear side of the busbar, and the second convex plate 910 and the second concave plate 903 clamp the front side of the busbar. The three cylinders 912 drive the connecting rod 911 to move to one side, which in turn pushes the front side of the first convex plate 909 and the rear side of the second convex plate 910 to move to one side, so that the rear side of the first convex plate 909 and the front side of the second convex plate 910 slide in the second slide groove 11. Thus, the first concave plate 902 and the second concave plate 903 gradually squeeze the busbar. When the included angle of the first convex plate 909 and the second convex plate 910 is the same as the included angle of the first concave plate 902 and the second concave plate 903, the busbar bending is completed. The third cylinder 912 continues to drive the connecting rod 911 to move to one side, and the front side of the first convex plate 909 and the rear side of the second convex plate 910 continue to move to one side to start pushing the first bending frame 901 to move. The two springs 907 contract, and the busbar is continuously squeezed during this process.
