Optical fiber laser cutting machine power station transformation, processing materials and branch transformation

Optical laser cutting machine power station transformation processing materials and division transformation projects are as follows:

1. According to the selected motor, process two 80mm and 50mm shaft sleeves, and the inner groove of the shaft sleeve.

2. Weld the coupling and the fan flange separately, the purpose is to ensure that the coupling, the fan flange and the motor shaft are coaxial and concentric, eliminate the vibration caused by the misalignment, and reduce the error (welding adopts The inlaid top pressure welding method can effectively eliminate the stress caused by welding).

3. Machining the flange of the vertical explosion-proof drive end cover and opening the inner diameter hole.

4. Process the transition gasket, open the inner diameter hole, process the concave and convex grooves, and connect with the motor flange transition plate inlaid bolts, the purpose is to eliminate the vibration of the concentricity of the motor and the hydraulic pump and reduce the error .

5. Machining the fan flange, inserting the pressure welding shaft sleeve, and installing the fan.

6. Process the welded hydraulic station base according to the measurement data of the whole machine, the base is made of 100mm channel steel welding, and the design reserves the position of the hydraulic oil tank, electric control box, and motor.

(2) Assembling division transformation project and processing materials, completing the transformation of the main body of the power station. The processing division transformation project and processing accessories and the original hydraulic station accessories are assembled and assembled. The transformation principle is that all the original hydraulic station accessories are used, and the unit modules before the power station are modified and repaired to achieve the purpose of saving costs. In the transformation, the motor end cover flange and the transition gasket and the transition flange are inlaid and connected to the groove to realize the one-time alignment and successful connection and eliminate the vibration of the unit. The transition disk fan is equipped with 6-blade clockwise rotating internal suction fan with a diameter of 380 mm. The original engine heat dissipation method is two-stage air-cooled heat dissipation between the oil cooler and the engine. The modified heat dissipation adopts an enlarged fan and the first-stage internal suction oil cooler and the motor dissipate heat at the same time. The heat dissipation effect is good after the modification. The radiator and hydraulic oil tank adopt the original machine accessories, and the adjusting valve changes the original installation position and is installed between the hydraulic pump and the motor. The design is more reasonable and convenient, and it is more convenient to adjust the pressure and install the hydraulic pipeline. Design and manufacture the electric control unit, which uses a 380V, 40A explosion-proof magnetic starter to realize motor protection and safe and convenient operation. After the transformation of the power station is completed, the power station and the fiber laser cutting machine, as well as the auxiliary pipelines and rails are assembled and designed to realize rapid loading during emergency operations.

After the transformation is completed, the test run uses a pipe with a test pipe diameter of Φ610mm*22mm, which is cut with a double bevel. After cutting the tube for 20 minutes, the temperature of each component tested is: hydraulic pump temperature 88°C, fuel tank temperature 71°C, oil filter temperature 71°C, motor temperature 58°C, cutter main motor temperature 80°C, and walking motor temperature 55°C. During this test run, the temperature was too high and the knife stuck. The reason for the technical demonstration analysis was that the pressure and flow were too small, or the hydraulic oil was selected incorrectly. Through continuous optimization and adjustment of parameters, the Shell anti-wear hydraulic oil L-HM46 was used instead The original hydraulic oil makes the pressure rise to working pressure and the temperature drops to within the working temperature range. The pipe cutting tool rotates at 55 rpm and the jamming phenomenon is eliminated. Choose Φ610mm*22mm pipe for cutting pipe diameter, and use double groove cutting. The pipe cutting starts at 15:10 and ends at 17:40. It takes 2 hours and 30 minutes. After the operation test, the pipe cutting tool has a speed of 55 rpm, no jamming, stable temperature, all indicators fully meet the technical requirements of the original hydraulic power fiber laser cutting machine, and meet the operating standards for the third test run (final test run), select The pipe diameter Φ610mm*8mm is cut with a single groove. The pipe cutting starts at 15:15 and ends at 16:32. It takes 1 hour and 17 minutes. During the whole trial run, the tool speed was 55 rpm, no jammed tool, stable temperature, and all indicators fully met the technical requirements of the original hydraulic power fiber laser cutting machine and the operating standards.

After the transformation of the tube-climbing machine power station, the various technical indicators meet the requirements of the original hydraulic station, the selection and configuration of the motor and electronic control unit are reasonable, and the measures for designing and processing accessories are appropriate. The hydraulic power station has a reasonable appearance design, which realizes the integration of the whole machine. Through the test run of pipe cutting with pipe diameters of different thicknesses, the quality of pipe cutting and safe operation of the modified equipment have been comprehensively improved, with no jamming and stable temperature. During rescue and field operations, the power hydraulic station of the pipe climbing machine can be equipped with the power supply of the rescue vehicle, which reduces the use of a fuel engine, saves fuel, reduces exhaust emissions, realizes the requirements of environmental protection and low carbon, and has a broad promotion prospect. Compared with purchasing new products, this hydraulic power station can save more than 500,000 yuan in cost by independent transformation under the same performance conditions, and the economic benefits are considerable.
