Title:
DEVICE FOR FLARING OPENING END OF GLASS TUBE
Document Type and Number:
Japanese Patent JPS59107932
Kind Code:
A
Abstract:

PURPOSE: To provide a titled device which permits easy flaring to a uniform shape by constituting said device wherein one opening end of a horizontally supported straight glass tube under rotation is heated to soften and the opening end is forcibly expanded from the inside to the outside by means of a flare lever.

CONSTITUTION: A straight glass pipe 3 is supported on a receiving part 4 provided to a lifting body 2 of a feed and discharge mechanism 1, and is carried into the space between a supporting part 9 and a gripping and rotating part 22. The non-working end of said tube 3 is supported by the collar plate 14 attached to a forward and backward moving rod 10 and a circular truncated cone-shaped supporting arm 11 provided with a circular truncated cone surface 13. On the other hand, the part near the working end of the tube 3 is gripped and rotated by the three rolls (not shown in the figure) which are moved forward and backward by the cam and spring in the part 22 operated by a cylinder 32, a rod 33 and a connecting rod 35; in addition, a thrust force is exerted on said part in the direction of the supporting part 9. The opening end is heated to soften in this state by a heating part 21, and a flaring part 15 mounted on a moving disc 18 is advanced into the opening end via a forward and backward moving rod 20 driven by a reversible motor 17, then a flaring lever 16 is driven by a motor 19, whereby the opening end is flared.
