Copper tube cutting device

Abstract

The invention relates to the technical field of cutting and processing, and discloses a copper tube cutting device. The copper tube cutting device includes a rack, and a knife head mechanism and a driving mechanism mounted on the rack, wherein the knife head mechanism comprises a cutting knife and a cutting table, and the head chamfer of the cutting knife is 25 degrees-40 degrees, the cutting table is opposite to the cutting knife, and the opposite end face of the cutter head is conic, the driving mechanism is rotatably connected with the knife head mechanism, and can drive the knife head mechanism to move along the direction perpendicular to the copper tube to be cut, and drive the knife head mechanism to rotate when the knife head mechanism is clamped tightly to the copper tube to be cut, and the knife head mechanism is clamped to the copper pipe to be cut while cutting, and the unstable cutting position is avoided, the driving mechanism drives the knife head mechanism to move, and simultaneously drives the knife head mechanism to rotate, the cutting knife and the cutting table squeeze the copper tube, the pipe mouth is internal contraction, while the pipe wall of the copper tubeis extruded into an inward tilt cone, so that the tube will not touch the finned tube when wearing the tube, thereby solving the problem of scraping aluminium scraps and aluminum powder at the mouthof long U copper pipe.

Description

Technical field [0001] The invention relates to the technical field of cutting processing, in particular to a copper tube cutting device. Background technique [0002] In the field of cutting processing technology, when the long straight section of copper pipe is cut into a certain length and then applied to products such as air conditioners and solar water heaters, the copper pipes used in the heat exchange parts of air conditioners use long U pipes to pass through the pipes. The other end is welded in the form of a small elbow to realize the connection of the copper tube of the entire heat exchange part. [0003] At present, due to the limitation of the production and manufacturing process, the long U tube cut by the existing cutting device has problems such as uneven tube mouth, external flanging, and pipe running. The heat exchanger of the air conditioner is not conducive to the long U tube when the long U tube is worn. The installation of the tube and the air conditioner heat...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the limitations of the manufacturing process, the long U tubes cut by the existing cutting device have problems such as uneven nozzles, flanging, and tube beating. On the other hand, the nozzle of the long U tube will scrape on the inner wall of the air conditioner heat exchange part, and then scrape aluminum chips and aluminum powder from the inner wall, and remain at the nozzle of the long U tube Aluminum shavings and aluminum powder will cause problems such as welding leakage when welding small elbows. Therefore, in order to reduce the risk of welding leakage caused by scraping aluminum shavings and aluminum powder at the copper pipe nozzle, a new type of copper pipe cutting device is designed. appears to be particularly important
