A wire stabilizing apparatus is also respectively installed on the wire entering mechanism and the wire collecting mechanism. The utility model is used in processing a three-dimensional-shaped cavity, which is of high processing precision, low processing cost and high processing flexibility and stability.
Description
Technical field
The utility model relates to a kind of generating electrode that is used for the machining 3 D die cavity.
Background technology
In the prior art, the common method of carrying out three-dimensional die cavity spark machined is an electrode copy processing method, it adopts shaped electrode, by control electrode progressively to the workpiece feeding, rely on the spark discharge between electrode and workpiece to come material unnecessary on the ablation workpiece, at last with the shape copying of electrode to workpiece.Its disadvantage is must produce the shaped electrode identical with the part to be processed shape in first being processed, and when the shape more complicated of part to be processed, the manufacturing of the shaped electrode comparatively difficulty that also becomes has increased manufacturing cost, has prolonged the production cycle.In order to overcome these problems, from the 1980s, Chinese scholars is through exploratory development, developed a kind of novel spark-erosion sinking process technology---electric spark milling processing, it adopts the normal electrode (as stick electrode) of simple shape under the control of digital control system three-dimensional die cavity or profile to be carried out the generate spark machined.Compare with traditional Electric Discharge Machining, design and manufacturing that shaped electrode has not only been saved in electric spark milling processing, shortened the production cycle of product, reduced processing charges, improve processing flexibility, and solved series of process difficult problems such as processing stability in traditional spark machined, capacity effect effectively.But because the export license that in electric spark milling processing, exists inevitably, and the loss of electrode directly influences machining accuracy.Up to the present, the compensation for electrode wear problem in the electric spark milling also is not well solved, and the application of electric spark milling processing is very restricted.By retrieval, do not find similar patent.
Summary of the invention
The purpose of this utility model provides a kind of machining accuracy height in order to solve above-mentioned deficiency exactly, and processing cost is low, and process flexibility and stability are high, has solved the generating electrode that can be used for the machining 3 D die cavity of compensation for electrode wear problem effectively.
The utility model is realized above-mentioned purpose by following technical proposals:
The utility model comprises support, adds the Ministry of worker, add the Ministry of worker comprise bar guide and the wire electrode that can on bar guide, move, this generating electrode also include the wire feeder that is used for the traveling electrode silk with can rotating supporting plate.Bar guide is provided with seal wire groove or godet roller.Described wire feeder comprises into a mechanism and wire drawing mechanism, enters the two ends that a mechanism and wire drawing mechanism are separately fixed at wire electrode.Describedly advance on a mechanism and the wire drawing mechanism also to be provided with steady silk device respectively.
Advantage of the present utility model is:
1, the utility model is installed on the three-axis numerical control electric spark machine tool, by to lathe X, and Y, the interlock control of Z axle promptly can realize carrying out with line electrode the spark machined in three-dimensional shaped chamber.
2, the utility model but also can utilize the line electrode in the generating electrode to move the export license that compensates in the processing has solved the difficult problem that export license is difficult to compensate in the electric spark milling processing, has great application value.
3, when the shape more complicated of part to be processed, when utilizing traditional electrode copy method, make the shaped electrode comparatively difficulty that becomes, increased manufacturing cost, prolonged the production cycle.And the utility model adopts generating electrode to add man-hour, and cost is low, the efficient height.
4, the utility model has improved processing flexibility, processing stability and machining accuracy height.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in Figure 1, comprise support 1, add the Ministry of worker, wire feeder, can rotating supporting plate 9.Add the Ministry of worker and comprise bar guide 4 and removable electrode silk 3, bar guide 4 is provided with the seal wire groove, also can adopt godet roller to substitute.Motor 2 is located on the support 1 and drives and connect with adding the Ministry of worker, is provided with bearing 10 between supporting plate 9 and the support 1, also can be roller.Wire feeder comprises into a mechanism 7 and wire drawing mechanism 8, mainly plays the effect of traveling electrode silk; Advance a mechanism 7 and wire drawing mechanism 8 be separately fixed at the two ends of wire electrode 3 and be installed in can rotating supporting plate 9 on.Advance also to be provided with steady silk device on a mechanism 7 and the wire drawing mechanism 8 respectively, mainly play the effect of steady silk.Advance and also be provided with guide wheel 5 and guide wheel 6 between a mechanism 7 and wire drawing mechanism 8 and the bar guide 4.
The utility model is by to lathe X, Y, the spark machined that realizes carrying out with line electrode the three-dimensional shaped chamber is controlled in the interlock of Z axle, utilizes the line electrode in the generating electrode to move the export license that compensates in the processing, has solved the difficult problem that export license is difficult to compensate in the electric spark milling processing.
By said structure as seen, the utility model low cost of manufacture has shortened the production cycle greatly, has increased processing flexibility, has improved processing stability and machining accuracy.
