Description
Technical field
The present invention relates to a kind of method of processing parts of vacuum condenser, be specifically related to the processing method of the electrode retaining collar on a kind of vacuum condenser.
Background technology
Vacuum condenser, as shown in Figure 1, mainly comprise two pieces of disc-shaped electrode dishes 1 and 2 and two groups of concentric circles tubular electrode retaining collars 3 and 4 and insulation crust 5, there is the clamping ring 6 and 7 of connecting electrode dish and insulation crust at two ends, wherein two groups of concentric circles tubular electrode retaining collars 3 and 4 are welded in electrode disk 1 and 2, and intercouple, become the electrode of capacitor, to be sealed in the shell 5 of insulation using vacuum as medium.
Electrode retaining collar is the cylinder electrode in vacuum condenser product, and they intercouple, and utilizes vacuum as medium, and forming property is stablized and the low capacitor of loss.The wall thickness of electrode retaining collar, diameter and height design according to the appearance and size of capacitor and capacitance value, operational voltage value.Because vacuum condenser operationally, two arrays of electrodes needs the high pressure carrying volt up to ten thousand, therefore each electrode retaining collar must be unanimously spaced, and surface should be smooth, impulse-free robustness, tip or impurity.Otherwise arcing between electrode can be caused, cause the moment of vacuum medium to puncture.
The electrode retaining collar processing of universal vacuum capacitor is undertaken by following processing technology: blanking → blanking extends → repeatedly transition extend → clean → to anneal → stretching of attenuation → cut circle → rounded corner → cleaning.Wherein, raw material are the no-oxygen copper plate of round sheet, in blanking extends operation, the raw material of round sheet are struck out cup shape, in order to the size making it reach expection, must to extend → clean → → stretching of attenuation operation of annealing through repeatedly transition again, and then the bottom of cup cut off make it present ring-type by cutting circle operation, and the length of electrode retaining collar is cut to meets the expected requirements, in order to avoid point discharge, rounded corner operation must be passed through again by the two ends rounded corner of electrode retaining collar.Above-mentioned conventional machining process needs repeatedly to extend, and extends at every turn and all needs special die clamper to ensure the precision of size.Because the surface smoothness requirements of electrode retaining collar is high, therefore the dimensional accuracy of this electrode retaining collar special mould and fixture thereof and surface smoothness requirements very high, the process-cycle of die clamper is long, and development cost is high.Thus the production time of causing electrode retaining collar to process is long, manufacturing cost is high.In each process of extending, all can cause the damage of electrode ring surfaces simultaneously, affect the fineness of electrode retaining collar.
Along with vacuum condenser product manufactures promoting the use of field in high-frequency heating apparatus field and solar facilities, requirements at the higher level are proposed to the price of product and the product quality of manufacturing cost and vacuum condenser, therefore must reduce production cost by process modification.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of electrode retaining collar processing method of vacuum condenser, processing method of the present invention not only increases production efficiency and the product quality of electrode retaining collar and vacuum condenser, and reduces the production cost of electrode retaining collar and vacuum condenser.
The present invention in order to the technical scheme solving its technical problem and adopt is:
An electrode retaining collar processing method for vacuum condenser, the raw material of electrode retaining collar are the no-oxygen copper plate of rectangle (or claiming oxygen-free copper stripe), the no-oxygen copper plate of rectangle are rolled into cylinder and shaping along bead direction straight seam welding (longitudinal measure).Welding sequence is the main operation in electrode retaining collar processing method; welding current and speed of welding depend on the wall thickness of electrode retaining collar, length and the Distance geometry shield gas flow rate value between electrode retaining collar and capillary; and the wall thickness of electrode retaining collar, length are according to the appearance and size of capacitor and capacitance value, operational voltage value and fixed; therefore welding current and speed of welding there is no concrete restriction in the present invention, need adjust according to specific product difference.Processing method of the present invention is mainly through changing raw-material shape, and by the no-oxygen copper plate raw material of rectangle being rolled into tubular and carry out straight seam welding at seam (weld seam) place shaping, this processing method is for traditional handicraft, eliminate and repeatedly extend and annealing operation and without the need to adopting special mould and fixture thereof, effectively can improve the production efficiency of electrode retaining collar, reduce production process, shorten the production cycle, and reduce in process the scuffing of material surface and pollution.
The present invention in order to the further technical scheme solving its technical problem and adopt is:
The raw material of described electrode retaining collar are that thickness is less than 2 millimeters and the surface roughness no-oxygen copper plate that is less than 0.8 micron.
In described welding process, adopt inert gas to carry out weld seam protection, avoid weld seam to be oxidized.
Clean after the no-oxygen copper plate of rectangle is rolled into cylinder, to remove the spot on cylindric no-oxygen copper plate surface, then carry out described straight seam welding.
After described straight seam welding (longitudinal measure) is shaping, obtain electrode retaining collar semi-finished product, electrode retaining collar semi-finished product are carried out cutting circle.Cutting circle is cut electrode retaining collar semi-finished product two ends, to make semi-finished product two ends smooth, and makes electrode retaining collar semi-finished product reach expection length.This is prior art, therefore does not add to repeat.
Rounded corner is carried out by cutting the electrode retaining collar semi-finished product after circle.Rounded corner is that radiussed is accomplished, to avoid point discharge in the two ends of half-finished for electrode retaining collar round.This is prior art, therefore does not add to repeat.
Electrode retaining collar semi-finished product after rounded corner are cleaned, to remove the spot of electrode retaining collar surface of semi-finished, obtained electrode retaining collar finished product.
The invention has the beneficial effects as follows: the electrode retaining collar processing method that the invention provides a kind of vacuum condenser, mainly through changing raw-material shape, and by the no-oxygen copper plate raw material of rectangle being rolled into tubular and carry out straight seam welding at seam crossing shaping, this processing method is for traditional handicraft, eliminate and repeatedly extend and annealing operation and without the need to adopting special mould and fixture thereof, when ensureing electrode retaining collar dimensional accuracy and surface smoothness, effectively can improve the production efficiency of electrode retaining collar, reduce production process, shorten the production cycle, and reduce in process the scuffing of material surface and pollution, the cost of manufacture of electrode retaining collar can also be made to decline more than 40%.
