Abstract
The utility model discloses a cavity blowing and pressing device for softening and bending glass tubes of fluorescent lamps, which comprises a vent pipe device. An air inlet is arranged at one end of the vent pipe device, an air outlet is arranged at a position of the vent pipe device close to a glass tube, a connecting fixing device and a roller device are arranged on a section of the vent pipe device with the air inlet, and one end of the connecting fixing device is connected with the vent pipe device movably. The vent pipe device which is slender is capable of not only blowing and pressing the glass tube but supporting the glass tube.
Description
Technical field
The utility model relates to a kind of fluorescent glass tubes blowing hold-down devices, relates in particular to the blowing hold-down devices that can practice thrift the anti-bending sagging increase counterweight glass-tube in two ends.
Background technology
Compact energy-saving fluorescent lamp; All be through the glass straight tube is softening, crooked through fusing (heating); And dwindle the linear length of discharge tube through connecing the one end fluorescent lamp that bridge is combined into, reaching again, common for example have: H shape, U-shaped, D shape, volution, quincunx, spherical.In various compact energy-saving fluorescent lamps, count quincunxly, the moulding of spherical sheet canal curvature is the most difficult, and it needs twice both direction brake forming.Plum blossom lamp shape is Chinese patent CN2610489, the CN3344198 of contriver's application for example; Globular light shape for example Chinese patent CN2502980, CN2582160, CN2710149, CN2710154, CN3303962, CN3171922, CN3585077, CN2561093, CN1674197, CN1830059 etc. is said; Its sheet pipe is all crooked through both direction; For example Chinese patent CN1528690 is said; Earlier the big section of glass straight tube is fused softeningly, bends to U-shaped like, and then by mould with the in-plane bent into shape.For satisfying the crooked requirement of above-mentioned both direction, need that the glass straight tube is carried out big section and fuse softeningly, vary in size according to processing lamp, fuse softening length at 10-30cm, account for sheet pipe length of straight pipe 2/3 and more than.A kind of glass-tube commonly used fuses softening, and CN1528690 is said like Chinese patent, and glass-tube is supported at both ends in the rolling e Foerderanlage, in advancing, needs crooked position to fuse gradually to softening glass-tube by big width flame.Two supports section broad in the middle fuses softening, and the objectively as easy as rolling off a log glass-tube middle part of causing fuses softening sag bent, and serious even sag bent drops on flame, not only causes the waste of glass-tube, and influences normal bend pipe moulding.Prior art is for guaranteeing that the two supports rolling is advanced, width broad in the middle fuses softening; Glass-tube does not drop because of fusing softening sag bent; Fuse the glass-tube two ends be provided with two can axial deciliter the mouth of pipe being in charge of down; Though this kind way can effectively be guaranteed two supports, big width and fuse not sag bent and drop its equipment used more complicated of glass-tube.
The utility model content
Goal of the invention: the purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, can reduce glass-tube consumption significantly and can effectively prevent to fuse the softening crooked interior empty blowing hold-down devices of the sagging fluorescent glass tubes that drops of glass-tube again.
Technical scheme: in order to solve the problems of the technologies described above; The utility model has adopted the softening crooked interior empty blowing hold-down devices of a kind of like this fluorescent glass tubes; Comprise submarine snorkel, be provided with inlet mouth, be provided with the air outlet near the glass-tube place at said submarine snorkel at this submarine snorkel one end; Be provided with connection stationary installation and roller devices in that section of said submarine snorkel inlet mouth; Connect stationary installation one end and submarine snorkel and flexibly connect through bearing, connect the stationary installation the other end and be fixedly connected on the lathe, roller devices is done periodicmotion through top roller.
On said submarine snorkel, be provided with counter weight device, this counter weight device is a threaded rod and some findings, and finding is to play the counterweight effect, confirms the size and the position of counterweight according to the requirement of blowing hold-down devices; This counter weight device also can be through being connected of spring and equipment, and reaches above-mentioned identical effect.
Said roller devices is fixedly connected with said submarine snorkel through screw, and the actual use location of roller devices is regulated through screw according to demand, at last screw tightening, makes vent-pipe and roller devices fix.
The softening crooked interior empty blowing hold-down devices of said fluorescent glass tubes does not need cylinder to wait a deciliter effect, so its used support equipment is fairly simple, has reduced manipulation strength.
Beneficial effect: the softening crooked interior empty blowing hold-down devices of the utility model fluorescent glass tubes, adopt elongated submarine snorkel, both glass-tube was played the blowing suppressing action, again glass-tube has been played auxilliary lining effect.
Description of drawings
Fig. 1 be former can axial deciliter the mouth of pipe down be in charge of scheme of installation;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the partial enlarged drawing at A place among Fig. 2.
Embodiment
As shown in Figure 1, a kind of fluorescent lamp slice pipe fuses softener, originally fuse the glass-tube two ends be provided with two can axial deciliter the mouth of pipe being in charge of down, it needs cooperations such as cylinder, just can play a deciliter effect; Of Fig. 2, Fig. 3; The softening crooked interior empty blowing hold-down devices of fluorescent glass tubes comprises submarine snorkel 1, is provided with inlet mouth 2 at these submarine snorkel 1 one ends; Be provided with air outlet 4 at said submarine snorkel 1 near glass-tube 3 places; Be provided with connection stationary installation 5 and roller devices 6 in said submarine snorkel 1 inlet mouth 2 those sections, this connects stationary installation 5 and said submarine snorkel 1 flexibly connects, and can link together through bearing between them; On said submarine snorkel 1, be provided with counter weight device 7; Said roller devices 6 is fixedly connected with said submarine snorkel 1 through screw 8; The top of the glass-tube 3 just in time of the air outlet 4 on the said submarine snorkel 1; Under the mating reaction of all parts; Air outlet 4 that section submarine snorkels 1 move up and down, and 1 pair of glass-tube 3 of submarine snorkel has played the blowing suppressing action, simultaneously glass-tube 3 has been played auxilliary lining effect; Empty blowing hold-down devices did not need corollary apparatus such as cylinder to come it is carried out the branch resultant motion in said fluorescent glass tubes was softening crooked, had simplified operational outfit.
