Description

Technical Field

[0001] The utility model relates to the technical field of steel-lined polytetrafluoroethylene pipe processing, in particular to a steel-lined polytetrafluoroethylene pipe assembly device. Background Art

[0002] Traditional metal pipes have many shortcomings: rough pipe walls, heavy weight, many joints, easy leakage, short service life, serious pollution to materials, etc. At the same time, non-metallic pipes have poor performance in mechanical strength, impact resistance, anti-aging, etc. The pipe has a large thermal expansion coefficient, is prone to rapid cracking, and the pipeline joints are easy to pull off, which limits its use and is not an ideal pipe material.

[0003] Steel-lined PTFE pipe is a composite structure of steel pipe and PTFE pipe. The PTFE pipe is installed in the steel pipe by applying external force, so that the PTFE pipe and the inner wall of the steel pipe are assembled by interference fit. The steel pipe bears the internal and external pressure of the pipe through interface bonding, and the PTFE pipe lining can play a role in corrosion prevention; the steel-lined PTFE pipe has the characteristics of metal hardness, rigidity, non-deformation, heat resistance, pressure resistance, anti-static, etc., and has the characteristics of plastic corrosion resistance, no rust, no stains, smooth pipe wall, good thermal insulation, clean and non-toxic, light weight, simple construction, long service life, etc.

[0004] When processing existing steel-lined PTFE tubes, it is often necessary to first process the PTFE tubes separately, and then assemble the processed PTFE tubes into steel tubes through machines. The operation is complicated and the work efficiency is low, which cannot meet people's use needs. For this reason, we propose a steel-lined PTFE tube assembly device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a steel-lined polytetrafluoroethylene pipe assembly device, which can assemble the polytetrafluoroethylene pipe with the steel pipe after processing it by itself, has simple operation, reliable structure, high working efficiency, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel-lined polytetrafluoroethylene pipe assembly device, comprising a workbench, a clamping unit and a processing unit;

[0007] Workbench: rectangular plate structure;

[0008] Clamping unit: comprising a clamping plate, a servo motor, a transmission gear 1, a fixing ring, a transmission gear 2 and a steel pipe clamping assembly. The upper end of the workbench is fixedly connected to the lower end of the clamping plate. A circular groove is provided on the surface of the clamping plate. The fixing ring is rotatably connected in the groove. The upper end of the workbench is fixedly connected to the lower end of the servo motor.

[0009] Processing unit: installed on the top of the workbench.

[0010] The workbench is used to support the main structure, and the clamping unit is used to clamp the steel pipe and the polytetrafluoroethylene pipe. The polytetrafluoroethylene pipe can be inserted into the fixing ring when in use. The polytetrafluoroethylene pipe needs to be rotated when processing the polytetrafluoroethylene pipe. The servo motor is started during rotation, and the servo motor drives the transmission gear 1 to rotate, and the transmission gear 1 drives the transmission gear 2 to rotate, and the transmission gear 2 further drives the fixing ring to rotate, which can drive the target polytetrafluoroethylene pipe to rotate for easy processing.

[0011] Furthermore, the steel pipe clamping assembly comprises a slide groove 1, a sliding clamping plate and a clamping hole. A longitudinal slide groove 1 is provided at the upper end of the workbench. The interior of the slide groove 1 is longitudinally slidably connected to two sliding clamping plates. Two corresponding clamping holes are respectively provided on the surfaces of the two sliding clamping plates. When it is necessary to clamp a steel pipe, the two sliding clamping plates can be slid in the direction of the slide groove 1 to separate them, and then the steel pipe is placed through the clamping hole. After the steel pipe is placed, the sliding clamping plate is closed in the direction of the slide groove 1, so that the clamping hole is closed to clamp and fix the target steel pipe.

[0012] Furthermore, it also includes a fixed plate, a hydraulic cylinder and a push plate. The left end of the upper surface of the workbench is fixedly connected to the lower end of the fixed plate, the left end of the fixed plate is fixedly connected to the right end of the hydraulic cylinder, and the output shaft of the hydraulic cylinder passes through the fixed plate and is fixedly connected to the left end of the push plate. During assembly, the hydraulic cylinder can be started, and the hydraulic cylinder drives the push plate to move the left end of the PTFE tube to the right through the push plate, and the PTFE tube is processed at the same time, and then the PTFE tube is pushed into the steel pipe for assembly.

[0013] Furthermore, the processing unit includes a U-shaped bracket, a second slide groove and a cutting assembly. The upper end of the workbench is fixedly connected to the lower end of the U-shaped bracket. Two vertical slide grooves are respectively opened at the front and rear ends of the U-shaped bracket.

A V-shaped cut is cut at the front end of the PTFE tube so that the front end of the PTFE tube can be contracted by a clamp during assembly to facilitate passing through the inside of the steel pipe. During cutting, the PTFE tube can be cut by the cutting assembly, and the PTFE tube can be rotated to make the V-shaped cut at the front end of the PTFE tube uniform.

When cutting, the telescopic cylinder 1 is started, the telescopic cylinder 1 drives the slider 1 to slide along the direction of the slide groove 2, and the slider 1 drives the V-shaped cutter to move vertically to cut the front end of the PTFE tube.

[0015] Furthermore, the processing unit also includes a slide rail, a telescopic cylinder 2, a slider 2 and a shrink clamp.

When in use, the telescopic cylinder 2 is started, and the telescopic cylinder 2 drives the slider 2 to slide along the direction of the slide rail, and further drives the two shrink clamps to close and aggregate the front end of the PTFE tube, which is convenient for assembly.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the steel-lined polytetrafluoroethylene pipe assembly device has the following advantages:

[0017] 1. In order to facilitate assembly, the PTFE tube needs to be cut. A V-shaped cut is made on the front end of the PTFE tube so that the front end of the PTFE tube can be retracted by the clamp during assembly to facilitate passing through the inside of the steel pipe. When cutting, start the telescopic cylinder 1, which drives the slide block 1 to slide along the direction of the slide groove 2. The slide block 1 drives the V-shaped cutter to move vertically to cut the front end of the PTFE tube. The PTFE tube can be processed by itself, which is convenient to operate and has high work efficiency.

[0018] 2. When it is necessary to clamp the steel pipe, the two sliding clamps can be slid along one direction of the slide groove to separate them, and then the steel pipe can be put in through the clamping hole. After putting it in, the sliding clamp can be closed along one direction of the slide groove to close the clamping holes to clamp and fix the target steel pipe. The inside of the clamping hole is made of a material with a large friction coefficient, which can avoid the PTFE tube pushing the steel pipe to move due to unstable clamping of the steel pipe during the assembly process, reducing work efficiency and making the device more stable.

[0019] 3. This steel-lined PTFE pipe assembly device can process PTFE pipes by itself. It is easy and quick to operate, has high work efficiency, and a stable working process, which can meet people's use needs. BRIEF DESCRIPTION OF THE DRAWINGS
