Embodiment Construction
[0015] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0016] Please refer to figure 1 , figure 2 and image 3 , the embodiment of the present invention quickly removes the method for quickly removing the oxide layer on the inner wall of the exhaust pipe of a multi-elbow racing car, the method comprising: using a high-pressure air pipe 2 with a stainless steel hose sheath, coupled with a spray gun 1 with a 360-degree rotatable nozzle 3 , the spray gun 1 is equipped with stainless steel shot blasting with a diameter of 0.5mm; the other end of the high-pressure air pipe 2 is connected to the compressed air station, and the spray nozzle 3 is inserted into the elbow of the exhaust pipe of the racing car. When the air spray switch 5 is turned on, The high-speed ejected gas will suck out the 0.5mm-diameter stainless steel shot blast and spray it on the surface of the workpiece, and move ...

The invention relates to a method for rapidly removing an oxide layer on the inner wall of a multi-elbow racing car exhaust pipe, and an apparatus thereof. The method is characterized in that the method comprises the following steps: using a high pressure pipe having a stainless steel flexible pipe sheath, and allowing a spray gun having a 360DEG-rotatable nozzle to be matched, wherein a stainless steel peen having a diameter of 0.5mm is arranged in the spray gun; and connecting the other end of the high pressure pipe to a compressed air station, forcing the nozzle into the elbow pipe of the racing car exhaust pipe, opening a blowing switch for sucking out the stainless steel peen having a diameter of 0.5mm by a sprayed high-speed gas and for spraying the stainless steel peen on the surface of a workpiece, and moving the nozzle at a speed of 30mm / s until the inner wall of the exhaust pipe is completely cleaned. The method and the apparatus have the advantages of fast use, easy operation, no pollution, low cost, and high efficiency.
Description
technical field [0001] The invention relates to a method and a device for quickly removing an oxide layer on the inner wall of a multi-bend racing car exhaust pipe. Background technique [0002] Since the engine power of a racing car is much larger than that of an ordinary car, and most racing cars are usually refitted from an ordinary engine, each component of the racing car should have different performance requirements when increasing the engine power of the car. The exhaust pipe is required to adapt to the temperature of 650°C-700°C, and can achieve non-fading, corrosion resistance, high temperature oxidation resistance and high temperature vulcanization, light weight, low price, easy processing, etc., iron-based Fe-Al metal Ceramic exhaust pipes meet these characteristics, but in the process of processing, cleaning the surface oxide layer inside the elbow and improving the adhesion of the ceramic layer are technical difficulties.
