Problems solved by technology

However, this kind of pipe bending processing method can only be processed once, and the processing efficiency is low, and the temperature of the pipe that has just been processed is high, it is inconvenient to manually disassemble, and the collection efficiency is low; secondly, in the prior art, The pipe fittings are heated through the heating box. The pipe fittings need to go through two steps of forming and bending. During the bending step, because the forming process has been carried out, there will be uneven heating of the inner and outer arc surfaces of the threaded pipe, resulting in thread The bending effect of the pipe is not good during the bending process of the remaining material, and the qualified rate of the product is not high

Embodiment 1

[0037] like Figure 1-Figure 7 As shown, the present invention discloses a multi-station bending equipment for producing spiral lamp tubes, including a workbench 1, and in a specific embodiment of the present invention, a straight pipe heating device 2 is installed on the workbench 1 , a longitudinal conveying device 3, a spiral forming device 4 and a pipe bending device 5 for continuous transportation of straight pipes; A number of spiral die heads 43 uniformly installed along the circumference of the first rotary table 42; the first rotary table 42 is rotationally connected with the first fixed seat 41 through a motor one 44 fixedly installed at the bottom of the workbench 1; the pipe bending device 5 includes a second fixed seat 51 fixedly installed on the workbench 1, a second rotary table 52, a clamping assembly 53 arranged to rotate along the circumference of the second rotary table 52 and used to clamp the workpiece on the spiral forming device 4, And the preheating de...

Embodiment 2

[0054] The present invention also proposes a processing method for producing a spiral lamp tube, comprising the following steps:

[0055] S1: Softening: transport the straight pipe to be processed to the longitudinal moving assembly through the first conveyor belt in the transportation device, and the vertical moving assembly will transport the straight pipe to be processed to the fixed groove of the heating box for heating and softening of the straight pipe ;

[0056] S2: Spiral forming: The straight pipe softened inside the heating box is transported downward through the longitudinal drive cylinder and the second drive support arm in the clamping part, and transported to the spiral forming device, and then passed through the spiral die on the spiral forming device. The softened straight pipe is spirally formed;

[0057] S3: Bending correction of remaining material: The spiral tube that has been spirally formed is transported to the right below the clamping device through th...

Description

technical field [0001] The invention relates to the technical field of lamp processing equipment, in particular to multi-station bending equipment for producing spiral lamp tubes and a production method thereof. Background technique [0002] At present, the common spiral lamp has the advantages of small size, and because of the advantage of the small shielding area between the lamps, the light can be irradiated at a larger angle to increase the brightness. Therefore, it is currently widely used and popular. Welcome lighting fixtures. [0003] The production method of the spiral shape of the lamp tube is traditionally a clamping part that can move up and down to hold a glass tube in a moldable high-temperature state above the spiral mold, and cooperate with the rotation and rising of the spiral mold to clamp the end of the glass tube. The part moves relatively to the central position, so that the glass tube can form a spiral tube shape along the periphery of the spiral mold....
