How to use the wire rubbing board for non-standard teeth rubbing machines

Non-standard teeth rubbing machineIt is a processing equipment for the outer surface of a cylindrical workpiece. The working principle of a non-standard tooth rubbing machine is: it is the same as the two pieces, and the thread-pulling surface has the same spiral angle as the bolt thread. When the thread-pulling plate moves each other, the thread-pulling plate is rubbed out the threads. The thread-pulling plate is processed one bolt thread at a time, and the speed is quite high. The thread-pulling plate is mostly used for small bolt processing. Summary: The thread-pulling is the processing of the outer surface of the cylindrical workpiece.

The installation and adjustment of the wire rubbing board of the non-standard tooth rubbing machine only requires the wire rubbing board to be installed in the moving mold groove and the fixed mold groove. There is no need for any thin pads or iron sheets under the mold. You only need to properly adjust the gap between the two wire rubbing boards, and then tighten and fix it. Adjust the gap between the two plates so that the blank can be pressed just enough. If the gap is too large, the blank will not be rubbed and fall off.

If the gap between the wire rubbing board of the non-standard tooth rubbing machine is too small, the blank will not enter the gap between the two plates. Similarly, the blank will not be rubbed and fall off. At the same time, adjust the gap between the upper and lower end surfaces of the 2-wire rubbing board by rotating the 2-wire rubbing bolts and the tension bolts. If the tightening bolts are tightened a little, the gap between the tail plate mold becomes smaller, and the gap should be adjusted to the depth of the rubbing thread until it meets the requirements.

When the wire rubbing machine of the non-standard tooth rubbing machine works for a long time, the friction surface between the sliding guide rail and the body guide rail will wear and tear. At this time, the upper and lower wire rubbing boards will have uneven surfaces, causing the rubbed thread to produce inclined lines (that is, the screws or bolts cannot be screwed into the nut), and waste threads such as self-tapping screws will be produced. At this time, a grinding or scraper is needed to restore the bottom surface and the fixed mold groove to the same plane.

For the time being, you can appropriately place some thin pads or iron sheets on the moving wire rubbing board to make the two wire rubbing boards on the same plane, but this will make the adjustment complicated and will make the product quality unstable. For this reason, when the wear is severe, the best way is to perform a grinding or scraper.
