Description
Technical Field
The utility model relates to a tensile mould particularly, especially relates to a from tensile mould of punching hole spiral.
Background
With the rapid development of machinery, machined products are applied more and more in daily life of people, so that the requirements of consumers on mechanical products are higher and higher, and precision products in the mechanical products account for a large part, so that the quality and the production efficiency of the precision products become the problems to be considered by producers.
At present, when a precision product is tapped, a workpiece clamp needs to be placed at a correct position, the center line of a threaded hole is placed at a horizontal or vertical position, and tapping is facilitated, so that whether the axis of a screw tap is perpendicular to the plane of the workpiece or not is easily judged. At the start of tapping, the tap is aligned as much as possible, pressure is applied to the tap and the reamer is turned, and the tap position is carefully checked and corrected as 1-2 cuts are made. Generally, when 3-4 turns of threads are cut, the position of the tap is correct. Later, only the wrench needs to be turned, and no pressure should be applied to the tap, otherwise the thread profile would be damaged. In addition, each time the reamer 1/2-1 turn, the reamer should be turned over about 1/2 turns, so that the chips are easy to discharge after being broken, and the phenomenon that the cutting edge rolls the tap due to chip sticking can be reduced. When a screw hole which can not be tapped is encountered, the screw tap needs to be frequently withdrawn, and chips in the hole are removed.
When the method is used for tapping a precision product, the problems of surface relation between the screw tap and a workpiece, pressure applied to the screw tap, position withdrawing and chip removal and the like need to be judged, so that the machining process is slow, the production efficiency is seriously influenced, and meanwhile, the quality of the precision product cannot be guaranteed.
