A special-shaped pipe bender for air conditioners and its operating method

Abstract

The invention discloses a special-shaped pipe bending machine for an air conditioner, and further discloses an operating method of the special-shaped pipe bending machine. The special-shaped pipe bending machine comprises a plurality of first-stage bent pipe feeding assemblies which are parallelly arranged at intervals, a second-stage bent pipe feeding assembly and a pipe fitting supporting assembly. The first-stage bent pipe feeding assemblies and the second-stage bent pipe feeding assembly are both arranged on a fixed rack and provided with pressure sensors, ultrasonic fault detectors and laser three-dimensional scanners. The pressure sensors, the ultrasonic fault detectors and the laser three-dimensional scanners are connected to a central processor. According to the special-shaped pipebending machine for the air conditioner, pipe fittings are pulled to be bent through the first-stage bent pipe feeding assemblies, the second-stage bent pipe feeding assembly and the pipe fitting supporting assembly, the bending precision of the special-shaped pipe fittings can be improved greatly, and a product can be expanded into more special shapes.

Description

technical field [0001] The invention relates to a pipe bending machine, in particular to a special-shaped pipe bending machine and an operating method thereof. Background technique [0002] Pipe bending technology is widely used in the production and manufacture of pipe bends in central air-conditioning, automobile industry, aerospace industry, shipbuilding and other industries. The quality of pipe bends will directly affect the structural rationality of products in these industries , safety, reliability, etc., and the feeding of the pipe fittings is mainly controlled by the booster device during the pipe bending process of the pipe bending machine. The front end of the device has reached the position of the anti-wrinkle plate on the bending machine head. At this time, the pipe pushing device cannot continue to move forward due to the restriction of the anti-wrinkle plate, so it cannot continue to provide force to the pipe.

[0002] Pipe bending technology is widely used in the production and manufacture of pipe bends in central air-conditioning, automobile industry, aerospace industry, shipbuilding and other industries. The quality of pipe bends will directly affect the structural rationality of products in these industries , safety, reliability, etc., and the feeding of the pipe fittings is mainly controlled by the booster device during the pipe bending process of the pipe bending machine. The front end of the device has reached the position of the anti-wrinkle plate on the bending machine head. At this time, the pipe pushing device cannot continue to move forward due to the restriction of the anti-wrinkle plate, so it cannot continue to provide force to the pipe. Push the remaining pipe fittings in the pipe fitting chuck out for processing. At this time, the remaining pipe fittings in the pipe fitting chuck become processing surplus materials and are wasted. At present, the mechanical pipe bending industry often uses push bending, pulling bending, winding bending, and pressing bending. When processing bent pipes in the same way, the bending mechanisms used are all one-way bending mechanisms. If a pipe needs to be bent in multiple directions in different directions, it can only be solved by changing the material, which is labor-intensive and requires replacement. The material process affects the processing accuracy and forming quality;

[0003] Chinese patent ZL201110438634 discloses a pipe bender. The pipe bender uses a driving mechanism to fix the first roller at the limit position corresponding to the root of the mandrel head of the guide structure to withstand the pipe material, and drives the second roller in another The guide structure moves from the limit position corresponding to the root of the mandrel head to the limit position corresponding to the end of the mandrel head. During this process, the tube material is bent by rolling the tube material with the second roller. Although the pipe bender can The pipe material is bent into Z-shape, W-shape and other shapes, but there are still the following problems: 1. The driving mechanism is set on the work table, which will hinder the formed part of the pipe material during the bending process, especially not It is beneficial to the bending of serpentine pipes with multiple bending parts; 2. The relative position of the two rollers needs to be changed during the bending process, which affects the accuracy of the bending pipe; 3. The bending pipe requires two driving mechanisms, which is not only complicated in structure, but also The requirements for the driving mechanism are high, and special-shaped pipe fittings with complex shapes cannot be produced
