Abstract
The utility model relates to a graphite heating element connecting structure in a vacuum furnace. The graphite heating element connecting structure comprises a graphite heating element base seat, graphite bolts, graphite screw caps and a graphite heating element. Bolt holes are respectively arranged at the feeler positions where the graphite heating element base seat and the graphite heating element are required to be connected, internal thread is machined in the holes, the graphite heating element and the graphite heating element base seat are connected through the graphite bolts matched with the bolt holes, and are further reinforced through the graphite screw caps. The graphite heating element connecting structure can ensure the stability of the current during the production process, and reduce the alloy liquid loss and the energy consumption; the service life of the heating element is effectively prolonged, and the consumption of the raw material is reduced, and the manufacture cost is lowered; the maintenance period of the production process is prolonged, the productivity is enhanced, and unexpected technical effect is attained.
Description
One, technical field
The utility model relates to heating graphite attachment structure in a kind of vacuum furnace, the syndeton of especially high electric current, high-power graphite heater.Belong to the machine components syndeton.
Two, background technology
Known graphite heater is connected with the graphite heater base, is to dig a groove on the graphite heater base, and the heater pin is inserted in the groove, injects alloy liquid with the wedging of graphite chock, heating back then, installs and uses after cooling again.The weak point of this method of attachment is that conductive area is little, electric current is unstable, installation procedure is loaded down with trivial details, the alloy liquid loss is big, heater useful life is short etc.
Three, summary of the invention
The purpose of this utility model provides heating graphite attachment structure in a kind of vacuum furnace, with the graphite bolt graphite heater and graphite heater base are coupled together, this syndeton is not only installed simple and convenient, and current stabilization, heater significantly improve useful life.
Fig. 1-the 3rd, composition structure chart of the present utility model.It comprises graphite heater base 1, graphite bolt 2, graphite nut 3, graphite heater 4.Respectively open a bolt hole 5 and car internal thread in the hole at graphite heater base 1 with the feeler place that graphite heater 4 needs to be connected, with the graphite bolt 2 that is complementary with this bolt hole 5 graphite heater and graphite heater base are coupled together, and further reinforce with graphite nut 3.
Advantage of comparing with known technology and good effect:
1), guaranteed the stability of electric current in the production process to reduce alloy liquid loss and energy consumption;
2) prolong useful life of heater effectively, reduced raw-material consumption, reduced production cost;
2), prolonged the maintenance period of production process, improved productivity, received unexpected technique effect
Four, description of drawings
Fig. 1 is the profile of the utility model graphite heater 4, and 5 is bolts hole among the figure; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is each parts assembling schematic diagram described in the utility model, and 1 is the graphite heater base among the figure, the 2nd, and graphite bolt, the 3rd, graphite nut, the 4th, graphite heater.
Five, embodiment
Structure as shown in Figure 3, it comprises graphite heater base 1, graphite bolt 2, graphite nut 3, graphite heater 4.Respectively open a bolt hole 5 at graphite heater base 1 with the feeler place that graphite heater 4 needs to be connected, and in bolt hole the car internal thread, with the graphite bolt 2 that is complementary with this bolt hole 5 graphite heater and graphite heater base are coupled together, and further reinforce with graphite nut 3.
