The purpose of this utility model is achieved through the following technical solutions:

Bend mechanism according to the fluorescent tube that the utility model proposes, comprise duration and degree of heating, bending apparatus, building mortion, also comprise anchor clamps; Wherein bending apparatus can be made the gap rotational displacement, and is provided with bend arm, and two anchor clamps are individually fixed on the bend arm with the clamping lamp tube ends; The duration and degree of heating that fuses softening fluorescent tube is positioned at the fluorescent tube periphery and also can rotates around fluorescent tube; Building mortion is positioned at the station that rotate in the bending apparatus gap, and the fluorescent tube after softening is moulded.In this mechanism, an important change is: in traditional technology, fluorescent tube need rotate and displacement when heating or molten state, and in the utility model, fluorescent tube before softening by the anchor clamps fixed clamp, need not after fluorescent tube is softening can be reduced transport process thus to finish crooked preliminary shaping and shaping, also reduce various motions and cooperate stack and the defective of fault in enlargement by gripping again; Because fluorescent tube is fixed by anchor clamps, can effectively control lamp tube ends length, also need not the clout waste that counterweight causes, reach the purpose that reduces the pipe consumption; And, after fluorescent tube is fixed by anchor clamps, under heated condition, do not do rotation or move axially, so can prevent from effectively also to be pulled into heating region because of the softening sagging fluorescent tube of hot spots that makes not of fluorescent tube, thereby can be accurately along fluorescent tube axis subregion and branch temperature control fluorescent tube softening degree, give security for the crooked preliminary shaping of good fluorescent tube, also be more suitable for being shaped on a large scale and bend purpose than the complex curve fluorescent tube.

Preferably, duration and degree of heating has two groups or more, lays respectively at fluorescent tube periphery and vertical with fluorescent tube, thus, can control fusing of fluorescent tube in the subregion; Every group of duration and degree of heating is made up of two duration and degree of heatings, and two duration and degree of heatings are 30-120 degree angle, and duration and degree of heating fuses focus and all points to fluorescent tube, more effectively fluorescent tube is fused.Described duration and degree of heating can rotate around fluorescent tube, perhaps/and leave and the moving radially of close fluorescent tube, like this, can fuse fluorescent tube more equably, also can be controlled the softening degree that fuses of fluorescent tube.

Swan neck system can be done the gap rotation and be shifted, and makes it be in different station, and cooperates with duration and degree of heating, building mortion, so that operation such as fluorescent tube fuses, preliminarily forming and shaping is finished at different station, like this, can improve fluorescent tube to bend efficient, also can simplify bending required mechanism, reduce error.

Bend mechanism by fluorescent tube described in the utility model, can bend, also can bend shorter fluorescent tube, effectively guarantee bending quality, qualification rate height, and efficient height the big fluorescent tube of shaped region; Fluorescent tube is fused and bending forming by the anchor clamps clamping, and the clout that fluorescent tube is bent significantly reduces, so the pipe consumption is little, has reduced production cost; In addition, also can reach complicated curved effect.The utility model can be widely used among the fluorescent tube processing.
