Abstract

The utility model relates to a bending device of fluorescent tube. The utility model is provided with an air port; therefore, the glass of the top end of the bending section of the U-type glass tube and the counter U-type glass tube meet the thickness requirement, so that the damage is reduced, and the percent of pass of the fluorescent tube is increased and the user is secure.

Description

The fluorescent tube bending apparatus

One, technical field:

The utility model relates to a kind of fluorescent tube bending apparatus, and especially related fluorescent tube bending apparatus has the air port.

Two, background technology:

Fluorescent tube is saved the energy because of its light efficiency height, has been widely used in various illuminations.Can make the compact fluorescent lamp of different shape now as the convenient use of incandescent lamp for making fluorescent lamp.Compact fluorescent lamp tube with U type and П type, generally be that a straight glass tube is constantly rotated, curve the U type in middle thermoplastic, enter mould then with flame, send into compressed air by pipe end, make the bend of glass tube after die for molding is U type or П type, make fluorescent tube again.The fluorescent tube of making like this is on the top of U type bend or the attenuation that is stretched during in moulding because of glass tube of two jiaos on П type bend top; In this production process afterwards and the fluorescent lamp finished product in use regular meeting cause the fragmentation of fluorescent tube top, influence the fail safe of the qualification rate of product and user use.

Three, summary of the invention:

The utility model aims to provide a kind of fluorescent tube and makes the two jiaos of fluorescent tube bending apparatuss that adequate thickness is arranged in its bend top or bend top when crooked.

In conjunction with embodiment of the present utility model, now particular content of the present utility model is described below:

1, the fluorescent tube bending apparatus by duration and degree of heating (4), air port (6) (6a), mould (7) (7a) etc. forms, and it is characterized in that having at least one or more air port (6) (6a).

The utility model fluorescent tube bending apparatus glass tube (1) (1a) stop the rotation heating back to mould (7) (7a) close before, the wind (5) that (6a) is blown out by air port (6) (5a) makes after the corresponding moulding the heated local glass (2) on glass tube bend top (2a) lower the temperature, and its viscosity is increased; Like this glass tube mould (7) (7a) in during moulding glass (2) (2a) be stretched less.Make after the moulding U type glass tube bend top or П type glass tube bend top reach enough thickness for two jiaos.

Because the utility model is provided with the air port, make that fluorescent lamp U type glass tube bend top, the two jiaos of glass in П type glass tube bend top reach enough thickness in the moulding, reduce damagedly, improved fluorescent lamp qualification rate and the fail safe used of user aborning.
