Description
Technical Field
The invention belongs to the technical field of chipless cutting processing of pipes, and particularly relates to a chipless cutting and stretch-breaking device for a metal flat pipe and a use method thereof.
Background
At present, porous aluminum flat tubes are increasingly used for replacing the prior copper tubes and steel tubes in cold and heat exchange equipment used in the fields of chemical industry, water heating, air conditioning and the like. The flat tube is a novel heat exchange material, the combination of the flat tube, the fins and the base tube replaces the traditional segment type combination, and aluminum materials and the like are commonly used for the flat tube. Because aluminum has good processing performance, copper pipes and steel pipes which can be processed into single holes in the past can be changed, and the porous aluminum flat pipes are formed at one time by using a hot extrusion mode, the width of the porous aluminum flat pipes used in the world at present is 6-220mm, the thickness is 1-20mm, the variety and the specification are extremely heavy, and the porous aluminum flat pipes are applicable to various industries requiring heat exchange from single holes to 62 holes. The largest application industry is the air conditioning industry at present, (including home and business air conditioners and automobile air conditioners.) but capillary holes, a booster valve and a compression pump are often arranged in the structure of the air conditioner, so that the aluminum scraps are never allowed to enter a heat exchange channel, and the prior chipless cutting mode of copper pipes and steel pipes cannot be suitable for a flat pipe cutting process: the rotary cutting and the cutting-in can not be performed, or the rotary cutting can be performed simultaneously, so that only saw blades can be used for cutting, aluminum scraps are inevitably generated after the saw blades are cut, compressed air is adopted to blow scraps (but not clean) after the saw blades are used for sawing, water washing is adopted (but the procedure is very complicated), the saw blades are dried after the water washing, the surface oxidation can be caused due to overlong process, and the scissors are adopted to cut off rapidly (but uneven fracture can be caused), so that the prior art cannot achieve the best effect.
In particular, the automobile industry is developing at a high speed at present, however, the air conditioner is installed in the automobile, which is fashionable and also necessary, and if the air conditioner is not installed in the automobile in hot summer, the automobile is driven on the automobile, so that the automobile is decocted. The micro-channel aluminum flat tube in the automobile is an important part in the automobile air conditioner, and the quality of the micro-channel aluminum flat tube directly influences the performance of the automobile air conditioner. At present, the technical field of cutting processing of micro-channel aluminum flat tubes is that the inner hole of the micro-channel tube is small, common toothed saw cutting is used for cutting to generate cutting scraps to block a pore canal, so that scrapping is caused, the overall cutting stability and accuracy are not enough, the yield is low, multiple people are required to operate, and the production efficiency is low. In addition, in the production process, the flat tube is cut straightly from the package, and the flat tube can be realized only by complex equipment combination.
At present, a chipless processing mode that a pipeline is broken after a part of the pipe wall is cut by a cutter can be used, the structure of the traditional device is complex, the operation of the cutting device is stable, the cutting accuracy is low, the yield is low, and the requirement of mass production cannot be met; in addition, all installation of the existing chipless cutting equipment is that a metal pressing plate clamps a pipeline, the metal pressing plate and the metal foreign matters are easy to electrostatically adsorb to cause the defects of pipeline crush injury and pipeline scratch, and the metal pressing plate is difficult to clean after the metal foreign matters are adhered to the metal pressing plate. The welding, service life and performance can be affected after the pipeline is scratched and pressed.
