Description
Technical field
The utility model relates to a kind of novel graphite resistor rod, belongs to graphite electrode technical field.
Background technology
At present at metallurgy, plating, in the industries such as high-accuracy mechanical processing, graphite electrode plays an important role in these industries, the stability that graphite motor runs and reliability are directly connected to the quality that Product processing is produced, and presently used graphite electrode is often solid graphite block structure, and end face separately to be gone between with copper by screw be connected, although this structure to a certain degree can meet the actual needs used, but in use this kind of electrode is when being energized, along with the conversion of temperature environment and electric current, electric current is uneven in electrode surface density distribution, thus cause electrode serviceability to decline, and easily cause processing precision of products not enough, simultaneously, the graphite of current electrode owing to being a monoblock, therefore in use easily outlet is cracked comes off and the drawback of heat dispersion difference, thus cause graphite electrode stability in use poor, therefore for this present situation, in the urgent need to developing a kind of novel graphite electric machine structure, to overcome numerous deficiencies that current graphite electrode exists, meet the actual needs used.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, provides a kind of novel graphite resistor rod.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of novel graphite resistor rod, comprise graphite matrix, conducting copper, lead-in wire end cap, connecting bolt and network for location, wherein conducting copper at least three, and be distributed in graphite matrix around graphite matrix axis, and its end is positioned at outside graphite matrix, conducting copper distance graphite matrix outer surface distance is 1/6-1/3 of graphite matrix radical length, conducting copper is positioned at that graphite matrix part is another to be connected by connecting bolt, end is electrically connected with lead-in wire end cap lower surface, lead end covers surface and separately establishes binding post, network for location is embedded in graphite matrix, and be coated on outside conducting copper, and the distance of network for location and graphite matrix appearance and conducting copper is not less than 5 millimeters, graphite matrix axis place separately establishes heat radiation air holes.
Further, be threaded connection or weld between described conducting copper with lead-in wire end cap.
Further, described conducting copper outer surface establishes screw thread to strengthen groove.
Further, described network for location mesh is not more than 1/5 of graphite matrix radius.
The utility model structure is simple, topology layout rationally and good stability, thus effectively improve the drawback of CURRENT DISTRIBUTION inequality in graphite motor on the one hand, also effectively slow down on the other hand graphite motor in use to come off cracked phenomenon, simultaneously, separately effectively enhance electrode heat dispersion, further increase electrode operation stability and reliability.
Accompanying drawing explanation
Fig. 1 is this novel structural representation;
Embodiment
