Abstract
The utility model relates to a discharge electrode for electrostatic powder spray guns; the discharge electrode is arranged at the end part of the spray gun body, wherein, the whole shape of the discharge electrode is lampshade shaped; a plurality of discharge tips are arranged at the external circumferential edge of the open end. The discharge tips are zigzag tips. The utility model has the advantages of uniform charged strength, high electric field intensity, and avoidance of damage to workpiece; meanwhile, as the discharge electrode can parallel with the surface of the work piece, the powder layer surface is not likely to breakdown, and no spark discharge is produced.
Description
The utility model relates to a kind of sparking electrode of electrostatic powder paint gun, the sparking electrode that especially a kind of charged probability that can make powder improves greatly.
In the external coating operation of various workpiece, because the effect of electrostatic spraying is better, it is increasingly extensive therefore to utilize electrostatic powder paint gun to carry out application.Existing electrostatic powder paint gun generally has two kinds of outer charged or interior charged formulas.The spray gun electrode of interior charged formula is positioned at powder channel, and the charged rate of powder is extremely low, present less application.The sparking electrode of outer charged formula spray gun is the single needle form, and the concrete structure schematic diagram as shown in Figure 1.The termination portion of spray gun body 1 is a sparking electrode 2, and body 1 is mainly the powder channel 3 of powder, and handle portion 5 is power supply, the powder break-make position of gauge tap high-tension cable 4.In the use, sparking electrode 2 energisings of needle point formula make powder charged, and charged powder is sprayed onto on the surface of workpiece.The sparking electrode 2 of needle point formula not only injures the surface of workpiece easily, and electric-field intensity is inhomogeneous, and the charged rate of powder is not high, and spraying effect is not good.
The purpose of this utility model is to provide a kind of sparking electrode of electrostatic powder paint gun, and the electric-field intensity of its electrode is not only even, and the intensity height.
The purpose of this utility model is achieved in that a kind of sparking electrode of electrostatic powder paint gun, and it is located at the termination portion of spray gun body, and wherein said sparking electrode global shape is a lampshade shape, and the circumferential periphery at open end place is provided with many discharge needle points.
Described discharge needle point is the zigzag needle point.
According to the technique scheme analysis as can be known, the utlity model has following advantage:
1, because the cylindrical of whole sparking electrode is the zigzag needle point, therefore charged intensity is even, and the electric-field intensity height.
2, sparking electrode no longer is an independent pin, and global shape is a lampshade shape, therefore is not easy the workpiece of damaging.
3, sparking electrode is parallel with surface of the work, therefore is difficult for puncturing the bisque surface, can not produce spark discharge.
Below in conjunction with accompanying drawing and concrete implementer's case the utility model is described in further detail.
Fig. 1 is the prior art structural representation;
Fig. 2 is arranged on structural representation on the lance head for the utility model;
Fig. 3 is the utility model needle point position concrete structure schematic diagram.
Shown in Fig. 2,3, the utility model is a kind of sparking electrode of electrostatic powder paint gun 1, it comprises spray gun body and the sparking electrode that is arranged on the rifle end of body, wherein the sparking electrode global shape is a lampshade shape 6, the circumferential periphery at the open end place of lampshade shape 6 is provided with many discharge needle points 61, and discharge needle point 61 is preferably and is the zigzag needle point.This structure has overcome the single needle discharge in the prior art spray gun, needle point directs at surface of the work, cause surperficial bisque to puncture easily, cause spark discharge, even causing the shortcoming that powder catches fire, and the zigzag needle point structure of cylindrical entire circumference has improved the intensity of electric field greatly, the charged rate of powder is further enhanced, the effect of spraying is improved.
