Abstract

The invention is a cathode ray tube (CRT) straight tube neck glass cone manufacturing process method, mainly firstly binding the semi-finished glass cone and a neck tube with hydraucone together, and then processing them in working procedure of cutting tube into the straight tube neck glass cone. The working procedure of cutting tube: firstly using driving mechanism to drive cutter blade to cut the neck tube, then using fire to heat the cut position to achieve the purpose of cutting neck tube. After cutting, it polishes the notches by heating at high temperature. When cutting, it firstly uses cutter blade to turn the inner of the neck tube a circle, to make the neck tube generate partial stress, then properly heats the neck tube so that the part prestressed will automatically break. In this mode, only when cutting will it generate an error, avoiding many errors generated by traditional process so as to obviously enhance productivity and performance.

Description

The technological method for processing of cathode-ray tube straight tube neck glass awl
Technical field
The invention belongs to the welding technology field of cathode-ray tube glass tube neck and glass awl, specially refer to a kind of technological method for processing of cathode-ray tube straight tube neck glass awl.
Background technology
In recent years, along with being growing more intense of market competition, the clients of glass bulb manufacturer have proposed many new technical needs one after another, and wherein the demand to straight tube neck glass awl is particularly strong.
In 2000, the method that industry is produced the straight tube neck generally was earlier neck to be cut into full-length, carries out sealing-in with cone again, adds the error that three aspects appear in trade union like this: the one, and during the neck cutting, the neck error in length; The 2nd, when cutting the microcephaly on the cone, envelope is wired to the reference line height error; The 3rd, when neck and cone sealing-in, the error that the sealing-in process produces.
Produce straight tube neck glass awl like this, precision is low, yields is low, and the process capability index of corresponding manufacturing procedure is also low.
Summary of the invention
The object of the present invention is to provide a kind of technological method for processing of straight tube neck glass awl, to overcome the weak point of above-mentioned process technology.This technological method for processing can improve the machining accuracy of straight tube neck glass awl, and is applicable to the technology of large-scale production.
To achieve these goals, technological method for processing of the present invention relies on following technical proposals to finish, a kind of technological method for processing of cathode-ray tube straight tube neck glass awl, it is characterized in that: be mainly earlier with semi-finished product glass awl be with bell-mouthed neck to seal, again semi-finished product after the sealing-in are become straight tube neck glass awl in the pipe cutter working procedure processing.Described operation at pipe cutter uses driving mechanism to drive the blade cuts neck earlier, is cut the place with the fire heating again, reaches the purpose of neck cutting.After the cutting, otch is polished by heat.The blade of described employing, its diameter D are that 5mm, thickness H are the diamond blade of 0.6mm.The described nozzles height H that is finished to use 1Be 7mm, diameter D 1Be 56mm, be respectively D at the diameter of nozzles 223mm, D 326mm, D 429mm and D 5There are four loop diameter D at the 32mm place 6Uniform for 20 apertures of 0.8mm, be divided into 18 ° mutually between per two apertures.
Advantage of the present invention and good effect:
This technological method for processing is with the awl of the intact neck of sealing-in, on pipe cutter neck is cut (as shown in Figure 1).During cutting, use blade (as shown in Figure 3) earlier, make it produce local stress, again neck is suitably heated, produce the position of stress in advance, will rupture automatically at inner car one circle of neck.Under this processing mode, only when blade cuts, produce an error, the multinomial error of avoiding conventional machining process to produce.The straight tube neck slope awl that uses this processes to go out, its height dimension precision reaches ± 0.1mm, and process capability index is that the production capacity of 2.3, three pipe cutting machines is 700 pieces/hour.So that production efficiency and performance all are significantly improved.

Embodiment
The embodiment that provides technological method for processing of the present invention below with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 is as follows:
Earlier the semi-finished product glass awl of the good neck of sealing-in on the conveyer belt is placed into the lifting platform of pipe cutter by loading machine; Along with lifting platform rises, cone positions under the acting in conjunction of lifting platform and top stationary positioned device (wear-resisting graphite annulus) then; After the location finished, blade place driving mechanism drove diamond blade, implemented cutting at inboard wall of tube neck, but this moment, neck can't rupture, and only can produced local stress by application of force place; After blade rotates a circle, return the home position, heat duration and degree of heating then and lighted, cutting part is heated, neat fracture that pipe will be from the place of original generation stress (position of being streaked by blade); Add the oxygen flow that thermal-flame uses and be 1.5-2.5L/min, pressure is 4 ± 0.5Kg/cm 2, gas discharge is 1-2L/min, pressure is 0.65 ± 0.05Kg/cm 2
Owing to may produce burr at fracture during cutting, after cutting finishes, the glass awl enters down station, otch is implemented flame polish to be handled, polishing nozzles (as shown in Figure 4) should be apart from neck otch 10-15mm during polishing, flame (internal flame blue streak) length is 2-3mm, and flame envelope length is at 110-130mm, and oxygen pressure is 4 ± 0.5Kg/cm 2, gas pressure is 0.65 ± 0.05Kg/cm 2, polishing continues 8 ± 1.5Sec.Until here, the work of whole neck cutting action also just is through with.
Equipment, parts and material used in above embodiment are commercial prod.
