Punch mould makes a technology reach its to use an analysis

Handle of the guide-post bushing that 1 turning machines turning to basically be used in treatment die, model, guide pillar and cylinder are sold wait for current part, the main technique that its process asks to have: Surface roughness of mutual position precision, geometrical appearance precision and dimension precision, surface. Round face can ask to undertake turning according to precision outside; The circumstance such as surface roughness of size of the structure that aperture surface needs to consider a hardware inside, material, aperture, ratio of pit-depth to pit-diameter, surface and precision, whether to machine in order to decide with the method of turning. 2.

2 milling treatment is made in die in, application is the widest is all-purpose tool milling machine and vertical milling machine, the aperture form that machining an object basically is all sorts of small-sized die spare partses and plane, and fixed head of aperture of makings of leakage of discharge board, sunken model, base, punch. And the treatment to large die, more adoption profile modeling milling machine. 2.

3 dig cut the dig that machines die spare parts to cut treatment facilities basically is double housing planer and shaping machine. Among them, because shaping machine is machining respect of die spare parts to have better economic effect and be applied extensively. It can machine plane already, also can machine oblique plane. Additional, when machining oblique plane, perpendicular feed and horizontal feed can undertake at the same time. 2.

4 insert in cutting treatment to be made in die, of the appearance treatment of large part and special spare parts inside aperture rough machining relies on slotting machine to finish. Use slotting machine to be able to machine the simple appearance datum plane that gives a few parts directly, if rush,cut modular rectangle or square into parts discharge board, fixed head and sunken pattern plate. 2.

Car of course of spare parts of die of 5 grinding treatment, mill, dig, after inserting, should undertake grinding is machined commonly, in order to improve its surface quality. According to the appearance difference of die spare parts, grinding treatment can be divided for figuration grinding, outside round grinding, inside the category such as grinding of face of round grinding peace. Spare parts of 3 die figuration makes spare parts of technical die figuration basically include punch-die, sunken model and punch to wait. This kind of spare parts because form is more complex, and precision requirement is general taller, besides can use common figuration car, mill, planing machine, outside grinding treatment, the introduction is emphasized below a few other treatment methods. 3.

The extruding of spare parts of 1 extrusion figuration is machined, main extrusion having heat and cold extrusion two kinds of methods. Optimum treatment sunken model or punch aperture appearance compare this method complex, and can become yield part group by group, like electromotor rotor piece reach stator piece punch-die. 3.

2 chemistry corrode figuration to be when production die, if quench the sunken model after or punch form are too complex, and quench when hardness is exorbitant, if benchwork undertakes nap is machined not easily, can use chemistry to corrode a law to machine. Corrode place to be aqua regia with solution, reason should notice in treatment process: (1) before chemistry is corroded, the mental allowance of punch-die should is 0.

1mm left and right sides, and the surface must undertake polishing; (2) control is good corrode time, edge edge etching answers to measure when be being operated, until appropriate till; (3) acid-proof on the place besmear that does not need to undertake cankerous nitro- varnish defends. 3.

Die of v of alloy of die of 3 alloy v is to point to the matrix in preform of die of steel of common carbon knot to go up, use soldering method, will the technique that steel of steel radical horniness or alloy steel v give its job position. The advantage of this technology depends on: (1) the service life that can improve die significantly; (2) saved precious steel products, reduced die to make cost; (3) the maintenance of facilitating die; (4) craft is simple, suitable scope is wide. 3.

Die of figuration of 4 benchwork nap manufactures production technology, centered the elite that machine, report machines almost, it is both union even sometimes. But no matter use which kinds of technology, cannot leave benchwork operation. Each edges and corners is the burr of place bequeath, smeary after die makes take shape wait with foreign matter, must rely on benchwork to come nap is finished. Spare parts of 4 accurate die makes a technology the article with report processing technique is exemple undertake summarizing. Report processing technique is one of advanced treatment methods in be being built to moulding, it is to use electric energy to press spare parts dimension and a kind of technique that appearance asks to machine figuration to metallic stuff directly. Its treatment precision is tall, quality of production spare parts is good, and the spare parts gets temper by dipping in water not easily influence of metabolic of igneous heat treatment, the application in developing moulding to build consequently is wide. 4.

Treatment of electric spark of treatment of 1 electric spark is to be based on electric spark to corrode a principle, below the circumstance of electrify, make scintilla arises to discharge between workpiece and electrode, fuse the metal, much heat energy produces when be being arranged, in order to achieve the goal of perforative treatment. Its application basically has: (1) those who machine all sorts of mould spare partses model aperture, if cold die is medium of discharge board, sunken pattern plate model aperture; (2) whorl aperture is machined in hard alloy; (3) grinding round cylinder and plane; (4) production alveolus (bore diameter 0.

015mm) . 4.

Shape cutting of 2 lines electrode processes this technique is technology of a kind of new electric spark treatment. In machining a process, because line electrode is not contacted with workpiece directly, consequently nonexistent cutting master piece is used, also won't arise likewise a series of technology issue. Its machine together with precision is taller, and realize automation control easily, saved labor power greatly. The limits that machines die has: (1) of the sunken model in die, punch, discharge board and fixed head guide form aperture; (2) aleatoric curve is narrow seam, miniature aperture chamfer; (3) the spare parts that can machine other method hard, the spare parts of as above round lower part. 4.

Electrochemical machining of 3 electrochemical machining is to use a metal to be below action of field of dispatches from foreign news agency, below the zincous and deliquescent effect that produces in electrolyte, make the spare parts processes a kind of technique of figuration. Use this technology, can undertake grinding to the spare parts, long grind, the treatment such as figuration and polish. The suitable scope of electrochemical machining object is wider, if cylinder is sold, guide-post bushing and guide pillar, spare parts antrum, and even figuration spare parts. 5 last words are current, die produces production technology to already made one of fundamental industry of national economy. As the progress of science and technology, existing production technology is being perfected stage by stage and rise. Meanwhile, a lot of new technology and new technology also will ceaseless emerge in large numbers, for die production industry offers new thinking, infuse more vigor. CNC Milling
