Description

Technical Field

[0001] The invention relates to the technical field of pipeline welding, in particular to a PTFE pipe welding device and a use method thereof. Background Art

[0002] PTFE tube, also known as polytetrafluoroethylene tube, is a high-quality plunger extrusion tube with reliable and excellent corrosion resistance. It can transport highly corrosive gases and liquids at high temperatures, which cannot be replaced by other pipes. When producing and processing PTFE tubes, laser welding is generally used to complete the assembly of multiple groups of PTFE tubes.

[0003] The existing Chinese patent application with publication number CN116690094A discloses a pipeline welding machine, comprising a base, two support frames on the top of which are respectively fitted with corresponding rotating rings, a limit ring is fixedly installed on the ring surface of the rotating ring, the two are coaxially arranged, and the limit ring is embedded in the side wall of the support frame of the base to form a rotation limit structure, and the two rotating rings are coaxially arranged; it also includes: a clamping plate, which has three equal angles distributed around the axis of the rotating ring, the clamping plate and the pipe body are located on the inner side of the rotating ring, and the pipe body and the rotating ring are coaxially arranged, and the three clamping plates are tightly fitted on the outer wall of the pipe body to form a fixed clamping structure, and the output end of the first electric cylinder is fixedly and vertically installed at the center of one side of the clamping plate away from the pipe body; this invention can quickly fix pipes of different diameters, and the device is provided with an automatic grinding structure for the pipe welding part, which does not require manual grinding by workers, thereby improving work efficiency and reducing labor intensity.

[0004] However, the pipeline welding device has the following defects when used specifically:

[0005] 1. When the existing pipeline welding device performs laser welding operations on various pipelines (including but not limited to PTFE pipes), in order to ensure the stability of the welding operation, the pipeline to be welded needs to be supported and fixed. However, when supporting and fixing the pipeline, the traditional solution generally uses multiple groups of electric cylinders to drive the output end clamping plate to move telescopically to achieve clamping and fixing. The assembly of multiple groups of electric cylinders will result in a high overall cost of the device. At the same time, each group of electric cylinders operates independently during clamping, and it is difficult to control the displacement of the output end clamping plate, and there is a risk of gaps in the clamped pipeline;

[0006] 2. When laser welding a clamped and fixed pipe (including but not limited to PTFE pipe), the existing pipe welding device generally uses the method of driving the pipe to rotate to perform laser welding operations on various points of the pipe. However, during the rotation of the pipe, it is easy to affect the clamping and fixing state of the pipe, which in turn causes the position of the pipe welding to be easily offset, affecting the effect of pipe welding.

[0043] The present invention also provides a method for using a PTFE tube welding device, comprising the following steps:

[0044] S1. First, move the welded PTFE pipe to the inner side of the arc support assembly, and use the arc support assembly to support and fix the PTFE pipe, so as to ensure that when the PTFE pipe is laser welded, the PTFE pipe will not be offset or shaken due to the vibration force generated by the laser welding, so as to ensure the accuracy of the PTFE pipe during laser welding;

[0045] S2, then start the pipeline docking assembly to operate, drive the two groups of PTFE pipelines to move towards each other, ensure that the welding points of the PTFE pipelines are close to each other and are arranged on the inner side of the annular welding assembly, and perform automated PTFE pipeline laser welding operations;

[0046] S3. When laser welding the PTFE pipes, the annular welding assembly is started to operate, and laser welding is performed on the outer sides of the connection between the two groups of PTFE pipes, so that the laser welding operation of the two groups of PTFE pipes is automatically realized;

[0047] S4. After laser welding is completed, one set of arc support components releases the support and fixation of the PTFE pipe.

[0048] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0049] 1. In the PTFE tube welding device and its use method, when the PTFE pipe to be welded is clamped and fixed, a group of second motors can be used to drive the first and second drive gears at the output end to rotate, and the two groups of arc-shaped tooth rods meshingly connected at the bottom of the first and second drive gears can be driven to rotate respectively, to ensure that the PTFE pipe can be clamped and fixed between the arc frame and the arc-shaped tooth rods. At the same time, the rotation of the two groups of arc-shaped tooth rods is achieved by the second motor driving the first bevel gear at the output end to rotate. At this time, the second and third bevel gears that are meshed can make the first and second drive gears rotate in opposite directions, and support both sides of the bottom of the PTFE pipe, to ensure that the PTFE pipe will not deviate or shake during subsequent laser welding. In addition, the cost of clamping and fixing the PTFE pipe is relatively low (driven by a group of second motors), which can effectively reduce the overall production cost of the pipe welding device;

[0050] 2. In the PTFE tube welding device and the method of using the same, when laser welding is performed on the PTFE pipe, the DC motor can drive the movable gear to rotate through the main gear, so that the two groups of laser welding guns installed on the inner side of the movable gear through the fixture can rotate 360 ​​degrees, and the laser welding operation can be performed on each point of the two groups of PTFE pipes that are in contact with each other. On the one hand, the efficiency of laser welding of the PTFE pipe can be improved, and on the other hand, the laser welding operation can be realized without rotating the PTFE pipe, which can effectively avoid the problem of affecting the clamping and fixing state of the PTFE pipe during the rotation process, thereby improving the quality of laser welding of the PTFE pipe;

[0051] 3. In the PTFE tube welding device and its use method, during the laser welding of the PTFE pipe, the first motor can be started to drive the first and second reciprocating screws connected to the output end to rotate, ensuring that the two sets of movable seats connected by balls on the outside of the first and second reciprocating screws and the clamped PTFE pipe can move, automatically approach, fit and move to the side of the laser welding gun to perform laser welding. At the same time, the operations of clamping, moving, laser welding and unloading the PTFE pipe are automatically controlled by the control panel, realizing automatic and intelligent PTFE pipe welding operations. In addition, the laser welding point and the quality of laser welding can be captured in real time by the camera end, which is convenient for control and adjustment to improve the effect of laser welding;

[0052] 4. In the PTFE tube welding device and its use method, the two sets of arc-shaped toothed rods are driven to rotate in opposite directions and the laser welding gun is driven to rotate 360 ​​degrees, both of which are realized by gear meshing transmission. At this time, the design of gear meshing connection can ensure the stability and accuracy of clamping and laser welding of PTFE pipes on the one hand, and on the other hand, it can improve the service life of the internal structure of the device during operation, and can sustainably carry out laser processing and production operations of several PTFE pipes.
