Abstract
The utility model discloses an explosion-proof machine heating electrode device, which is adopted in the explosion-proof operation if the manufacture flow path of color kinescope. The electrode made up by copper material is taken as a heating element to heat the explosion-proof steel belt made up by ferro-nickel alloy to 500-600DEG C, the explosion-proof steel belt is sheathed on the side skirts of the screen of the color kinescope by using the heat expansion and cold contraction characteristic of metal, and then rapidly blast cooling the explosion-proof steel belt to make it have a fastening function to the screen. The device made in this manner, has good explosion-proof performance, high heating efficiency, evenly heating of the explosion-proof steel belt, simple process, and capability of satisfying explosion-proof operation of various types of color kinescopes.
Description
Technical field
The utility model belongs to picture tube and makes the field, relates to blast proof steel strap heater in a kind of colorful visualization pipe manufacturer, particularly a kind of explosion-proof machine heating electrode device.
Background technology
Color picture tube is after manufacturing is finished, high vacuum state is pumped in the glass bulb inner space, its volume is very big again, if color picture tube is subjected to the bump of external force, trickle other factors such as scar are perhaps arranged on the glass bulb, color picture tube just might break, and the phenomenon that bursts under vacuum state is exploded exactly like this.This blast is under the effect of atmospheric pressure, and poor owing to having little time by the crack compensatory pressure, micro-crack will expand whole envelope surfaces rapidly to.Glass bulb just becomes fragment in moment like this, and because of action of pressure, fragment begins inwardly then outwards to fly out, the explosion time glass fragment to around disperse, will jeopardize televiewer's personal safety.Therefore, when making color picture tube, design special explosion precaution.
At present, all color picture tubes have all been taked the safety anti-explosive measure when dispatching from the factory, screen side shirt edge assigned position at color picture tube heats explosion-proof band then around all adhesive tapes, utilize the metal characteristic of expanding with heat and contract with cold to be set on the assigned position of screen side shirt edge of color picture tube, and blowing cooling rapidly, make it play fastening effect to screen.Can apply certain prestressing force (compression stress) to the severe stress district of glass bulb like this, offsetting the tension stress in a part of severe stress district, thereby the actual tension stress in glass bulb severe stress district be reduced greatly, therefore improve the stability of glass bulb.Simultaneously, if glass bulb bursts, plastic deformation can take place in the blast proof steel strap that has been fastened on the screen side shirt edge thereupon, will absorb the energy of blast, has reduced the danger of blast, has improved the security protection performance greatly.
The heating means of present explosion-proof band have: high-frequency heating and coal gas heating, adopt the coal gas heating to need a lot of auxiliary devices, and some unsafe factors have been brought to production, therefore do not advocate employing, and the high-frequency heating apparatus cost is high and harmful health, can not become the best heating means of explosion-proof band.
The utility model content
The purpose of this utility model is the defective that overcomes above-mentioned prior art, a kind of explosion-proof machine heating electrode device is provided, this explosion-proof machine heating electrode device is simple in structure, can carry out the adjustment of size, position, shape according to the colour picture tube anti explosion steel band of different cultivars, different model.
The purpose of this utility model solves by the following technical programs:
This explosion-proof machine heating electrode device comprises blast proof steel strap, it is characterized in that: be provided with pair of electrodes on the described blast proof steel strap at least, described electrode is provided with the via hole of fixedlying connected with blast proof steel strap, and described electrode is electrically connected with described blast proof steel strap.
Above-mentioned blast proof steel strap is provided with pair of electrodes, and described pair of electrodes is located at the opposite side of blast proof steel strap respectively.
Above-mentioned blast proof steel strap is provided with two pairs of electrodes, and described two pairs of electrodes are uniformly distributed on the blast proof steel strap.
Above-mentioned electrode size can be mated according to blast proof steel strap width size.
The installation site of above-mentioned electrode on blast proof steel strap can be adjusted according to the length and width size of the blast proof steel strap of different size.
Above-mentioned electrode is the red copper material.
Above-mentioned blast proof steel strap is a dilval.
Explosion-proof machine heating electrode device of the present utility model adopts the mode of electrifying electrodes that blast proof steel strap is directly heated, not only simple and reasonable for structure, dependable performance, and firing rate is fast, the efficient height, be heated evenly, technology is simple, has overcome the defective of present high-frequency heating apparatus cost height, harmful human body.And this kind device can carry out explosion-proof operation to the blast proof steel strap of plurality of specifications, can satisfy the colour picture tube anti explosion operation of various models.
Description of drawings
Fig. 1 is an electrode schematic diagram described in the utility model;
Fig. 2 is that electrode described in the utility model is assemblied in the blast proof steel strap schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1 and Fig. 2, explosion-proof machine heating electrode device of the present utility model, comprise blast proof steel strap, described blast proof steel strap is electrically connected with electrode, described electrode is fixedlyed connected with described blast proof steel strap through via hole, described electrode is located on the blast proof steel strap in pairs, to heat blast proof steel strap, at least need pair of electrodes to be set thereon, it among Fig. 2 the situation when pair of electrodes is set, to logical low-voltage, high-current alternating current or direct current on the pair of electrodes, electric current just flows on the blast proof steel strap by the conduction of electrode, and blast proof steel strap adopts dilval, has bigger resistance value, make electric current in blast proof steel strap, do work and give birth to heat, thereby play the effect of heating blast proof steel strap, this heating electrode can make blast proof steel strap at short notice temperature be increased to 500 ℃～～～600 ℃, utilize the metal characteristic of expanding with heat and contract with cold blast proof steel strap to be set on the assigned position of panel of color picture tube side shirt edge, and blowing cooling rapidly, make it play fastening effect to screen.
