There are a batch of long copper rods (200-600m.) in our factory which need to be knurled. According to the conventional processing method, add two center holes first, then knurling. There is eccentricity when the copper rod is clamped, and the processed center hole deviates from the center of the copper rod. During the knurling process, relatively large vibration will occur, and the pressed pattern will vary in depth. Later, J Lin used the method of adding a top set on the tail center, which eliminated the factory machining center hole. Pull sequence, when knurling, no vibration occurs, and the rolled pattern is relatively uniform, which is improved by adults. Improved labor efficiency and obtained good economic benefits. As shown in Figure 1, add a top sleeve 3 at the center of the tail (Figure 2), and choose a clearance fit between the counterbore and the copper rod, that is, J: larger than the diameter of the copper rod. Figure 1. Self-centering with three jaws Chuck 2. Copper rod 3. Top sleeve 4. Tail center 5. Tailstock 0.15-0.25mm, counterbore depth 4-6mm. The cone of the tail center bears against the pill hole, d: the aperture is 8 to 12 nlm. d. The cylindrical part of the counterbore and the tail center is selected for light interference with Figure 2 When adding knurling, the copper rod extends into the counterbore d, and the other end is clamped by a two-two-jaw self-centering chuck,.): Tighten the center of the tail and it can be processed. Long copper rod knurling does not need to drill the center hole Guangxi Pingnan Plumbing Equipment Factory! 537307 Our factory has a batch of long copper rods (200600mm) that need to be knurled. According to the conventional processing method, the center hole is processed first, and then the knurling is performed. When the copper rod is clamped, there is eccentricity, and the processed center hole deviates from the center of the copper rod. During the knurling process, relatively large vibration will occur, and the pressed pattern will be of different depths. Later, by adding a top sleeve to the tail center, the process of machining center holes was eliminated.
