Abstract

The utility model discloses a forming device for a lighting tube spiral forming machine. The forming device mainly adopts a structure that the top part of a die is provided with a positioning groove, the periphery of the die is provided with a double spiral forming groove, the die is arranged on a threaded rod, the upper part of the threaded rod is provided with threads and is in threaded connection on a nut which is arranged on a stander, the lower part of the threaded rod is provided with a guide key which is matched with a guide groove inside a transmission wheel, the lower part of the threaded rod and the transmission wheel are respectively sleeved inside a fixed bracket, and the transmission wheel is matched with an external bending pipe engaging driving mechanism and rotates positively and reversely to drive the die to lift and descend spirally. The forming device has simple and compact as well as reasonable structure, realizes that the forming die spirally lifts and descends stably, improves the lighting tube spiral forming quality, produces the spiral lighting tubes with different spiral length specifications and is suitable for various lighting tube spiral forming machines with a plurality of stations.

Description

The shaped device of tube helix tube shaper

Technical field

The utility model relates to a kind of tube helix tube forming production device, a kind of more precisely shaped device of tube helix tube shaper.

Technical background

The Double-spiral power saving fluorescent lamps is in the bend pipe moulding, mould needs rotation simultaneously to rise during bend pipe, mould then needs to rotate simultaneously decline when moving back pipe, the tube helix tube shaped device of public use at present, adopt cylinder to promote the bigger screw rod of spiral angle, promote the bend pipe mould spiral lifting by screw rod and nut threaded again, the pipe speed of sending when its rising or falling speed is difficult to lamp tube formation is complementary, screw rod and nut right alignment are poor during simultaneously owing to rotation, amplitude of fluctuation is very big during the mould rotation, cause the tube helix tube Forming Quality poor, the scrap rate height is difficult to realize the tube helix tube shaping automation.

The utility model content

Deficiency at the prior art existence, thereby provide a kind of shaped device of simple in structure, compact, rational tube helix tube shaper, can realize the steady spiral lifting of fluorescent tube bent pipe mold, and the pipe speed of sending when mould spiral lifting speed can be by lamp tube formation is regulated control, make the tube helix tube moulding process controlled fully, improve the tube helix tube Forming Quality.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of shaped device of tube helix tube shaper, employing mould top is shaped on locating slot, the mould periphery is shaped on the duplex forming tank, mould is installed on the screw rod, screw rod top is shaped on screw thread and is screwed onto on the nut, nut is installed on the support, and the screw rod bottom is shaped on feather key, and the guide path in feather key and the power wheel matches, screw rod bottom and power wheel are set in the anchor, and power wheel cooperates forward and backward to drive the mould spiral lifting with the outside curved pipe engagement driving mechanism that moves back.

The duplex forming tank pitch of described mould is consistent with screw flight pitch.

Compared with the prior art the utility model has the following advantages:

The utility model is simple in structure, compact, reasonable; Screw rod top adopts the screw thread of less spiral angle and nut to be spirally connected, the screw rod bottom cooperates by the up and down keyway of feather key and power wheel, can realize the steady spiral lifting of bend pipe mould, and the pipe speed of sending when mould spiral lifting speed can be moved back pipe engagement driving mechanism by lamp tube formation by the outside is curved is regulated control, make fluorescent tube bend pipe moulding process controlled fully, improved quality product; Can produce the fluorescent tube of different helix length specifications with rotating cycle by the rotating speed of adjusting power wheel simultaneously, be particularly suitable for various multi-work-station tube helix tube shapers.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

The utility model is mainly by bend pipe mould 1, nut 2, support 3, screw rod 4, compositions such as power wheel 5 and anchor 6, the utility model adopts mould 1 top to be shaped on locating slot 11, the mould periphery is shaped on duplex forming tank 12, mould is installed on the screw rod 4, screw rod top is shaped on screw thread 41, screw flight partly is screwed onto on the nut 2, nut is installed on the support 3, the screw rod bottom is shaped on feather key 42, guide path 51 in feather key and the power wheel 5 matches, screw rod bottom and power wheel are set in the anchor 6, and power wheel is by just cooperating with the curved pipe engagement driving mechanism that moves back in outside, counter-rotating drives the mould spiral lifting.

Principle of work of the present utility model: because the screw rod bottom connects by up and down keyway with power wheel, screw thread position, screw rod top is spirally connected with the nut that is installed on the support, after roasting soft fluorescent tube base pipe is put into the locating slot of bend pipe mould by clamp mechanism (or manual) clamping of tube helix tube shaper, the curved pipe engagement driving mechanism that moves back is just changeing the bend pipe mould spiral that drives screw rod and be installed in above the screw rod with the power wheel engagement and is rising in the outside of shaping station, and clamp mechanism send pipe to finish the work of bend pipe spiral forming along the spiral angle inclination of bend pipe mould duplex forming tank simultaneously; After the cooling of moulding fluorescent tube, curvedly in the outside of moving back the plumber position move back that pipe engagement driving mechanism drives screw rod with power wheel engagement counter-rotating and the bend pipe mould spiral descends, the pin of the clamp of shaper or cutting agency (or by hand) clamping moulding fluorescent tube withdraws from fluorescent tube from the bend pipe mould forming tank simultaneously.

Outside of the present utility model is curved moves back pipe engagement driving mechanism and can adopt by the stepper-motor of rotating control device control or servomotor and drive meshing gearwheel through band synchronously, again by meshing gearwheel and power wheel engaged transmission, can accurately control the rotating speed and the rotating cycle of the rotating of power wheel, the spiral lifting action that makes bend pipe mould is complementary with the pipe speed of sending of the clamp mechanism of shaper, also can adjust the rotating speed and the number of turns of power wheel, and then the rotating cycle and the speed of adjustment bend pipe mould, thereby produce the helical lampl of different helix length specifications.

The utility model can be produced needs according to helical lampl, customizes the close or consistent duplex forming tank mould of threaded thread pitch and is installed on the screw rod, thereby produce helical lampl with the close or consistent different pitch specifications of screw flight pitch.
