Description

Technical Field

[0001] The invention belongs to the technical field of micro-channel zinc-sprayed aluminum flat tube processing technology, and specifically relates to a process for eliminating aluminum chips on the surface of a micro-channel zinc-sprayed aluminum flat tube. Background Art

[0002] Microchannel aluminum flat tube (also known as "parallel flow aluminum flat tube") is a thin-walled porous flat tubular material made of refined aluminum rods through extrusion. It is also called "zinc-sprayed aluminum flat tube" after surface zinc spraying anti-corrosion treatment. It is mainly used in various air-conditioning systems. It uses new environmentally friendly refrigerants and is a key material for the new generation of parallel flow microchannel air-conditioning heat exchangers. The development of condensers is divided into three stages: the first is the tube sheet type (expansion tube type), the second is the tube belt type (serpentine tube type), and the third is currently the parallel flow condenser. The heat dissipation pipeline has also changed accordingly, with round tubes (above Φ8mm), large porous flat tubes (thickness above 3.5mm) and micro porous flat tubes (thickness 1mm-2mm). Microchannel flat tubes are special components for R134A environmentally friendly refrigerant bearing pipelines. Due to their high efficiency, environmental protection, low cost, light weight and high reliability, they were first used in automotive air conditioning systems (EU regulations in 1996, China regulations in 2002). They are mainly divided into pointed flat tubes, square flat tubes, internal tooth flat tubes, triangular hole flat tubes, double-row connection flat tubes and other special-shaped flat tubes. Microchannel aluminum flat tubes will be zinc-sprayed during processing. Before zinc spraying, the aluminum chips on the surface of the microchannel aluminum flat tubes need to be removed to ensure the quality of the product after zinc spraying; After searching, the Chinese patent with the authorization announcement number CN221871386U discloses a deburring device for aluminum tube processing. Through the joint action of the fixing frame, the lower arc frame, the upper arc frame and the first electric push rod, the grinding port of the aluminum tube can be clamped and fixed, and the other end of the aluminum tube is supported by the arc seat, thereby improving the stability of the aluminum tube fixation. Through the joint action of the movable plate, the shell, the through hole, the conduit and the box, the shell is used to wrap the grinding part to prevent the waste chips from splashing everywhere, and then the waste chips are introduced into the box through the conduit for collection.

The rocker arm 303 is fixedly installed on the output shaft of the reduction motor 302 and is located at the top of the support plate 301. The eccentric pin 304 is fixedly installed on the rocker arm 3 03, and away from one end of the output shaft of the reduction motor 302, the push-pull block 305 is fixedly installed on the side of the bottom of the support platform 201 away from the motor fixing seat 2010, the top of the push-pull block 305 is penetrated downwardly by a path groove 306, the outer wall of the eccentric pin 304 is slidably connected with the inner wall of the path groove 306 through a bearing, the linear slider 307 is fixedly installed at the four corners of the bottom of the support platform 201, the linear guide rail 308 is fixedly arranged on the top of the front and rear pick plates 102 in a left-right distribution manner, and the linear guide rail 308 is slidably connected with the linear slider 307.

[0023] Specifically, when the microchannel aluminum flat tube makes a linear motion inside the sandpaper belt 205, the output shaft of the reduction motor 302 drives the rocker arm 303 and the eccentric pin 304 to rotate, so that the eccentric pin 304 generates an eccentric force, thereby pushing the push block 305 to move back and forth under the sliding connection between the eccentric pin 304 and the path groove 306, thereby driving the bearing platform 201 to move forward and backward together. Since the bearing platform 201 is guided by the sliding of the linear slider 307 and the linear guide rail 308 , which can ensure the stability and smoothness of the reciprocating movement of the supporting platform 201. The reciprocating movement of the supporting platform 201 drives the two front and rear fixed seats 202, the two front and rear tightening rollers 206, the sandpaper belt 205 and the tensioning block 203 to move together, so that the sandpaper belt 205 can perform reciprocating kneading movement on the outer wall of the microchannel aluminum flat tube.

[0024] In this solution, the microchannel aluminum flat tube passes through the upper and lower aluminum flat tube clamping rollers 400 and the sandpaper belt 205, and one end of the microchannel aluminum flat tube is fixedly connected to the conveying section of the external winding device, and the microchannel aluminum flat tube is continuously wound by the external winding device, so that the microchannel aluminum flat tube moves linearly inside the upper and lower aluminum flat tube clamping rollers 400 and the sandpaper belt 205; The output shaft of the servo motor 2011 drives the active synchronous wheel 2012 to rotate, thereby driving the driven synchronous wheel 209 to rotate together under the transmission action of the synchronous belt 2013, and then driving the screw rod 208 to rotate inside the support platform 201. Since the screw rod 208 is connected to the thread hole 207 through a thread, the rotation of the screw rod 208 will push the tension block 203 to move downward. The downward movement of the tension block 203 is affected by the sliding connection of the correction slide groove 215 and the side wall of the support platform 201, which can provide a tensioning force for the tension block 203. The tension block 203 moves downward accurately to guide the downward movement, so that the tension block 203 moves downward more stably and smoothly. The downward movement of the tension block 203 drives the sandpaper belt 205 to move downward, and the sandpaper belt 205 is tightened around the periphery of the microchannel aluminum flat tube under the winding action of the front and rear tightening rollers 206. After the sandpaper belt 205 is tightly wrapped around the periphery of the microchannel aluminum flat tube, the servo motor 2011 is turned off to ensure the wrapping effect of the sandpaper belt 205 on the microchannel aluminum flat tube. After that, the microchannel aluminum flat tube makes a linear motion inside the sandpaper belt 205. During the process, its outer wall is constantly rubbed against the grinding surface of the inner side of the sandpaper belt 205 to remove the aluminum chips attached to the surface of the microchannel aluminum flat tube; at the same time, the output shaft of the reduction motor 302 drives the rocker arm 303 and the eccentric pin 304 to rotate, so that the eccentric pin 304 generates an eccentric force, and further pushes the push block 305 to move back and forth under the sliding connection between the eccentric pin 304 and the path groove 306, thereby driving the bearing platform 201 to move forward and backward together. The sliding guiding function of 308 can ensure the stability and smoothness of the reciprocating movement of the supporting platform 201. The reciprocating movement of the supporting platform 201 drives the two front and rear fixed seats 202, the two front and rear tightening rollers 206, the sandpaper belt 205 and the tensioning block 203 to move together, so that the sandpaper belt 205 can perform reciprocating kneading motion on the outer wall of the microchannel aluminum flat tube. Through the linear motion of the microchannel aluminum flat tube itself and the friction of the inner wall of the sandpaper belt 205, multi-dimensional grinding of the microchannel aluminum flat tube is realized, and the effect of eliminating aluminum chips is improved.
