Air pipe linking machine

Abstract

The invention provides an air pipe linking machine. The air pipe linking machine comprises a driving assembly arranged at the top end of the whole device, wherein a workbench is arranged under the driving assembly, the workbench comprises a first workbench, a second workbench is oppositely arranged on one side face of the first workbench, two guide wheels and two first working wheels are arranged on the bottom surface of the first workbench in the air pipe linking direction, a gear assembly is arranged on the workbench, and a height adjusting assembly is arranged on the second workbench. According to the air pipe linking machine, the distance between the first workbench and the second workbench can be flexibly adjusted, then the linking requirements of air pipes with different specifications can be met, meanwhile, the height control between the second working wheel and the workbench is realized, then the linking requirements of the air pipes with different specifications can be met, the height of the two working wheels during working can be flexibly adjusted, and then the quality of the bent edges of the air pipes is improved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to an air duct sewing machine. Background technique [0002] Portable air duct joint sewing machine, also known as pneumatic air duct joint joint machine, iron air duct joint joint machine, is a new type of air duct production hot-selling tool. The portable air duct seaming machine mainly uses high-pressure gas and its own special hammer to act on the seam of white iron to effectively achieve the sewing effect. It is mainly suitable for the production of professional air ducts such as ventilation and drainage pipes and white iron sheet metal. , Fan volute seam and curved elbow seam, seam row, curling, etc., the application range is: heating and ventilation system engineering, chimney engineering, building outdoor facilities, industrial ventilation system. [0003] Therefore, this portable air duct seaming machine is different from the traditional manual seaming method. Usin...

Problems solved by technology

[0003]Therefore, this portable air duct seaming machine is different from the traditional manual seaming method. Using a portable seaming machine not only greatly improves the product forming speed , and the noise is low, and the seaming effect is beautiful, but when the portable air duct seaming machines on the market currently seam the thin plates, due to the difference in the thickness of the thin steel plates, there is a phenomenon that the seam is not in place, so that The air duct has the possibility of being broken. In addition, when switching thin steel plates of different thicknesses, it is difficult to accurately control the working gap between the two workbenches of the portable pipe branching and jointing, so that when the switch is made, the steel plate is in the latter thickness. The product defect rate of air duct products is relatively high

[0004] At present, there is this kind of portable air duct seaming machine on the market, which can also adjust the stainless steel used to clamp the air duct according to the thickness of different plates. The gap between the two worktables of the plate is adjusted, and there are different gears for plates of different thicknesses. The height of the seaming machine table should also be different. In the existing device, the height of the drive roller and the seaming machine table is determined by adjusting the height of the drive shaft in the seaming machine motor. This method is difficult to be flexible Adjust the distance between the working wheel and the workbench properly, resulting in quality problems in the bending edges of the entire air duct
