Rolling wire processing is a multi-functional cold extrusion forming machine tools, rolling machine can be in its rolling pressure range in the cold state of the workpiece thread, straight, oblique rolling and other treatments; is an advanced non-cutting processing, can effectively improve the inherent quality of the workpiece and the surface, processing of the radial compressive stress can significantly improve the workpiece’s fatigue strength and torsional strength, is a highly efficient, energy-saving, low-consumption of the ideal technology.
1, adjust the distance Adjust the distance between the three axes, so that the distance between the three rolling die for the rolling workpiece roughly into an equilateral triangle, and open the hydraulic manual gear, adjust the cylinder nut against the plug, so that the activity of the guide rail of the rolling die to send over just to touch the workpiece being rolled.
2, to the teeth
First, roll half tooth (that is, only one section of the workpiece is threaded, the length is not greater than the maximum size of the mold wheel)
1. Color the thread rolling place of three-axis thread rolling machine with a color pen, manually loaded into the three die wheels between, with a foot switch to the movable guide rail die wheel up to squeeze the workpiece.
2. Turn the pulley by hand, so that the workpiece on the three die wheel silk screen just into a circle, and then look at the three silk screen is connected, if it is not connected, then the three die wheels in any one of the benchmark, loosen the other two die wheels behind the connecting axle connected to the gear box, rotate the scale, and so on and so forth until the three sections of the silk screen connected to a good into the thread print.
3. After the threads are connected, start the main power and cooling pump, put the workpiece, while rolling, while adjusting the cylinder stroke, once not in place shall be adjusted several times, so that the thread depth to reach the standard and requirements. Which must pay special attention to the pressure of the hydraulic pump should not be too high, should be between 35kg / s, in order to avoid damage to the mold wheel due to high pressure.
4. Automatic rolling: After the standard thread is formed, open the hydraulic automatic gear, adjust the time relay according to your own needs, adjust the automatic rolling and back time arbitrarily, rapid cycle rolling.
Second, roll the whole tooth (i.e. the whole screw)
1. Loosen the two compression nuts on the three bearing seats, gently swing an angle, so that it is adjusted close to the rising angle of the rolling threads, and then lock the compression nuts on the bearing seats.
2. The steps for thread alignment and rolling are the same as for half-thread rolling.
