Abstract
The invention provides a punching technology. The punching technology comprises the following steps of: firstly, performing a semi-fine boring on a blank; installing a punching head, of which the diameter is slightly larger than the pore diameter of the blank by several microns, on a drilling machine or manually punching machine; extruding the punching head into a hole of a workpiece, wherein the surface of the punching head is smooth; the head of the punching head is provided with a small fillet; under the condition of proper interference, the punching head can extrude and flatten concave and uneven tool marks in the hole, so that the smoothness inside the hole can be improved, the pore diameter can be properly corrected, and products with unqualified blank pore diameters can be indentified and screened according to an extruding force; the punching technology has the characteristics of simple process, high production efficiency and the like; and the qualified rate of the pore diameters of the products can reach 99.9%.
Description
Technical field
The present invention relates to a kind of punching technology.
Background technology
Generally speaking, tolerance is that 0.01 aperture processing way all is that right boring technology is processed, because the right boring feeding speed is slower, production efficiency is not high yet, and can't guarantee that a large amount of productions the aperture substandard product can not occur.
Summary of the invention
The object of the invention provides a kind of production efficiency high to above-mentioned situation exactly, the punching technology that product percent of pass is high.The object of the invention can be realized through following scheme: a kind of punching technology, at first blank is adopted half reboring, and use a diameter drift bigger several microns slightly to be contained in then and bore on art or the hand punch than blank aperture; Drift is squeezed in the hole of workpiece; Said punch head surface is smooth, and the head of drift has little fillet, and drift is under the magnitude of interference situation that is fit to; The uneven tool marks of indent in the hole are flat through extruding stem; So both fineness in the hole can be provided, revise aperture size in right amount, can discern the defective work in screening blank aperture simultaneously through the size of extruding force.It is simple that the present invention has technology, characteristics such as production efficiency height, and the qualification rate in product aperture can reach 99.9%.
Claims (1)
1. punching technology; It is characterized in that at first blank being adopted half reboring, use a diameter drift bigger several microns slightly to be contained in then and bore on art or the hand punch, drift is squeezed in the hole of workpiece than blank aperture; Said punch head surface is smooth, and the head of drift has little fillet.
