Abstract
The utility model relates to an electrode bar connecting device, which comprises a stainless steel electrode bar and a blind hole flange, wherein the blind hole flange is inserted into the stainless steel electrode bar through an electrode blind hole which is formed at the center of the blind hole flange; and the blind hole flange is provided with a ring of seal grooves. The electrode bar connecting device provided by the utility model has the beneficial effects that the stainless steel electrode bar and the blind hole flange are in the welding connection, so an air leakage phenomenon at the joint of the stainless steel electrode bar and the blind hole flange can be avoided because a welding line connection position is cracked due to temperature variation.
Description
Technical field
The utility model relates to a kind of improved electrode assembly, relates in particular to a kind of electrode bar jockey.
Background technology
Electrode assembly is the intermediary that connects heating element in vacuum furnace external power (band voltage regulator) and the vacuum furnace, and heating element is heated processed workpiece smoothly.Gland adopts the copper electrode rod to be connected with the gas welding of through hole simple steel flange in the existing electrode assembly; This device is in copper rod and through hole flange torch weld junction; Because fluctuation ratio is bigger up and down with working condition for temperature in the vacuum furnace stove, causes weld seam junction cracking, and then makes between copper electrode rod and the through hole simple steel flange junction and produce gas leak phenomenon; Influence the normal use of vacuum furnace, therefore necessaryly carry out certain improvement.
The utility model content
To above defective, the purpose of the utility model provides a kind of excellent electrode bar jockey that does not have gas leak phenomenon with flange connections, helps practicing thrift cost of stainless steel electrode of guaranteeing, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of electrode bar jockey comprises stainless steel electrode rod and blind hole flange, and said blind hole flange inserts the stainless steel electrode rod through the electrode blind hole of its center position, offers a circle seal groove on the said blind hole flange.
The beneficial effect of the described electrode bar jockey of the utility model is: adopt the stainless steel electrode rod to be connected through electric welding with blind hole flange, can avoid producing gas leak phenomenon because of the weld seam junction receives the variations in temperature cracking at stainless steel electrode rod and flange connections.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the described electrode bar jockey of a utility model structural representation.
Among the figure:
1, flange gland; 2, seal groove; 3, blind hole flange; 4, stainless steel electrode rod.
Embodiment
As shown in Figure 1; The described electrode bar jockey of the utility model; Comprise stainless steel electrode rod 4 and blind hole flange 3, said blind hole flange 3 inserts stainless steel electrode rod 4 through the electrode blind hole of its center position, offers a circle seal groove 2 on the said blind hole flange 3; Stainless steel electrode rod 4 arranged outside insulating parts, blind hole flange 3 outside mounting flange glands 1.
Claims (1)
1. electrode bar jockey; Comprise stainless steel electrode rod (4) and blind hole flange (3); It is characterized in that: said blind hole flange (3) inserts stainless steel electrode rod (4) through the electrode blind hole of its center position, offers a circle seal groove (2) on the said blind hole flange (3).
