Technical field

The invention relates to improvement, relate in particular to a kind of bend pipe efficient and finished product height, save the brake forming device of glass-tube single-ended fluorescent lamp slice pipe bending and molding device.

Background technology

Single-ended fluorescent lamp slice pipe, no matter be the U type, still flower is distinguished type or lotus flower lamp sheet pipe etc., all be by the glass straight tube through bend pipe, move into two processes of mould typing, for example feed pressed gas and make the mellow and full typing of crooked glass-tube, or go into to feed the slick and sly typing of pressed gas after mold pressing is bent again.For example simple U-shaped sheet pipe, straight tube becomes U-shaped through thermoplastic by the involutory bend pipe in mechanical manipulator clamping glass-tube two ends, moves into and can finalize the design in involutory/divided mould; Lotus flower lamp sheet pipe becomes U-shaped or U-shaped roughly by the involutory bend pipe in mechanical manipulator clamping glass-tube two ends, moves into the typing of bending of involutory/divided mould then.

Prior art fluorescent lamp slice pipe bending (Figure 17), all be thermoplastic straight glass tube 7 to be taken over from heating unit earlier by a pair of mechanical manipulator 29 is straight, close up action simultaneously in opposite directions, the straight glass tube bend pipe is become U-shaped or U-shaped roughly, by another mechanical manipulator 28 is taken over then and put into shaper and finalize the design.This bend pipe mode all has been so to the invention one end fluorescent lamp, any change is not arranged, by industry is given tacit consent to.This bending method and device exist not enough: for example two processes of bend pipe need to finish through the handing-over of second mate's mechanical manipulator, the i.e. glass straight tube involutory bend pipe of first pair of mechanical manipulator after with thermoplastic, and then send into final shaper position after taking over by the second secondary mechanical manipulator, close up typing (U matrix pipe) or the typing (for example lotus flower lamp sheet pipe) of bending by mould, for satisfying second mate's machinery affiliative need lengthening fluorescent tube termination, increase length and behind bend pipe, also need excise this in the operation, increased the invalid and waste of the required process section of technology of fluorescent tube, simultaneously to special relatively shorter pipe of some not molten soft section requirements, because of supreme delivery position down, also inapplicable mechanical bend pipe can only rely on manual bend pipe; Secondly, because of need second mate mechanical manipulator handshaking, thereby cause the corresponding reduction of shaping speed, production efficiency is carried not high; The 3rd, handover procedure can make molten soft Glass tubing because of the handing-over time lengthening, can produce change of shape, and produces shake during handing-over, all can cause the curved tabs pipe to go into the mould qualification rate and reduce, and increases scrap rate.And the shaping speed that the handing-over of this second mate's mechanical manipulator brings is low, and it is low to go into the mould qualification rate, increases technological process and invalid glass-tube waste three big shortcomings, and people also know, but fail for a long time effectively to be solved, and perplex the single-ended fluorescent lamp slice pipe bending moulding for a long time.The disclosed bend pipe of Chinese patent CN1762869 is processed with 4 steps, first step is that the position, center of glass-tube is heated, with described glass-tube to curved, second step be with to the glass-tube even heating after curved to softening temperature, the 3rd step is to be heated to softening temperature curved back glass-tube is placed on the bend pipe mould, utilize tube-bending machine to carry out bend pipe, the 4th step is at described glass-tube the crook to be connected a vapor pipe.

For reducing the distortion of softening glass-tube in handshaking, improve and go into the mould qualification rate, the applicant is at first to file 200810123373.2 both direction curved fluorescent lamp sheet canal curvature forming method and devices, after bending to U-shaped like for the first time, close up shaping by the both sides shaping mould, then by the involutory bent into shape of mould.Only be to meet follow-up press-bending and go into mould shape qualification rate and consider from improving crooked U-shaped glass-tube.Therefore still having is worth improved place.
