The rack is also provided with a roller, the roller is positioned above the guide rail, and the surface of the roller positioned above the groove is provided with an annular bulge along the circumferential direction.
When the guide rail passes through the surface of the needle outlet, the needle in the needle box is received, after the needle is placed, the guide rail returns, at the moment, when the roller descends to contact with the surface of the guide rail, the guide rail drives the roller to rotate, and the annular protrusion is pressed into the groove to bend the end part of the needle.
The technical scheme can be further perfected as follows.
The roller is provided with an automatic lifting device, and the roller can ascend or descend through the automatic lifting device.
The surface of the guide rail is inclined, and an included angle is formed between the surface of the guide rail and the horizontal plane.
The needle outlet of the needle box is parallel to the surface of the guide rail, and the needle outlet is abutted against the surface of the guide rail.
The roller surface is parallel to the guide rail surface.
And a needle groove is formed in the position where the needle is placed on the surface of the guide rail, and the depth of the needle groove is smaller than that of the groove.
The position of the needle on the surface of the guide rail is provided with a magnet, the magnet is arranged in the guide rail body, and the magnet does not protrude out of the surface of the guide rail.
The needle swinging and bending machine has the advantages that the structural design is reasonable, the guide rail moves back and forth, the needle swinging and bending processes can be realized, the speed is high, the automation degree is high, and the guide rail, the needle box and the roller are obliquely arranged, so that the weight of all needles cannot be completely pressed at the needle outlet.
