Abstract
The invention discloses a machining method of a valve element. The problem that the performance of a control valve is influenced because the weight of the valve element is large is solved. The method includes the steps of material preparation, lathing, thermal processing, bench work, grinding, bench work, surface processing, grinding, bench work and the like. The valve element machined through the method is resistant to wear, small in weight, stable in quality and capable of meeting the requirement for the use performance of a precise control valve.
Description
Technical field
The present invention relates to a kind of processing method of spool, belong to field of machining.
Background technology
Spool is the vitals in control valve, in order to improve the wearability of spool, spool material selects the steel that intensity is large usually, but steel spool certainly focus in fine control valve the performance affecting control valve, particularly bulky valve core, its Heavy Weight, greatly can affect the performance of control valve, cause control valve cisco unity malfunction.Devise a kind of spool, the material of its spool is aluminium alloy, lightweight for this reason, and spool face after treatment wearability is equivalent to the steel part that hardens.This kind of spool is wear-resisting, lightweight, thus meets the serviceability of control valve, stabilizes product quality.
Summary of the invention
The technical problem to be solved in the present invention is: the processing method providing a kind of spool, and by processing method of the present invention, spool is wear-resisting, lightweight, steady quality, thus meets the instructions for use of control valve accuracy.
The present invention is achieved in that it comprises the following steps:
The first, get the raw materials ready: choose aluminium alloy bar;
The second, Vehicle Processing: each cylindrical of turning and groove, and car breaks to corresponding length;
Three, drill centers: clamping above-mentioned aluminium alloy bar two ends respectively, at its two ends drill centers;
Four, tapping thread: internal thread in centre bore inside fire attack respectively;
Five, heat treatment: workpiece is heat-treated;
Six, pincers processing: repair and grind two ends centre bore 60 ° of conical surfaces;
Seven, mill processing: with heart carrier clamping workpiece one end, the Double ejection pin of lathe holds out against two ends centre bore, heart carrier drives workpiece to rotate, cylindrical grinding;
Eight, pincers processing: repair burr clearly;
Nine, surface treatment: adopt the mode of anodic metal oxide process to process surface of the work.
Compared with prior art, the spool of the present invention's processing is wear-resisting, lightweight, steady quality, can meet the serviceability of fine control valve completely.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the spool that need process
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the invention will be further described:
Please refer to Fig. 1, concrete procedure of processing is as follows:
1, get the raw materials ready: aluminium alloy bar, aluminium alloy bar, in advance through cutting process, leaves certain allowance.
2, Vehicle Processing, drill centers and tapping thread:
(1) bar A end is clamped on lathe, hard three-jaw folder cylindrical A end, car aluminium alloy one end face, brill, car centre bore and internal thread hole, tailstock center holds out against centre bore, more rough turn cylindrical, made allowance.
(2) stop, change the direction of aluminium alloy bar and clamp B end, car other end, brill, car centre bore and internal thread hole, tailstock center holds out against centre bore, more rough turn cylindrical, made allowance.
(3) clamp cylindrical, tailstock center holds out against centre bore, half fine turning outer circle, and cylindrical stays allowance, and the cannelure that car is each section is to the size needed.
3, heat treatment: artificial aging, temperature 140 ± 5 DEG C, insulation 6 ~ 7h.
4, pincers processing: repair and grind two ends centre bore 60 ° of conical surfaces.
5, mill processing: be loaded on aluminium alloy one end with heart carrier, the Double ejection pin of lathe holds out against two ends centre bore, heart carrier drives workpiece to rotate, cylindrical grinding.
6, pincers processing: repair burr clearly, sharp edge rounding is not more than 0.05mm.
7, surface treatment: carry out anodic metal oxide, the electrode of surface processing equipment connects with electric conductor with between workpiece, with screw, aluminium alloy bars is fixed to the electrode union end place of surface processing equipment, aluminium alloy bars with workpiece union end is made external screw thread, and connect with the internal thread of workpiece termination, the other end of electrode connects minus plate, puts into oxidation trough and carries out anodic oxidation.
