Embodiment 1
[0033] Reference attached figure 1 Attached Figure 4 , The present invention includes a support platform 7; the support platform 7 is provided with a push mechanism, a sleeve cutting mechanism, and a transfer mechanism that are connected end to end from the front end to the rear end; a straight line is provided between the push mechanism and the sleeve cutting mechanism. A clamping mechanism in which the guide rail 40 and the support platform 7 are slidably connected to each other; the transfer mechanism is provided with a supporting guide block 13 sleeved in the film 12;
[0034] The pushing mechanism is provided with a plurality of pushing sliding rollers 25 corresponding to each other horizontally, and the pushing sliding roller 25 is rotatably connected with the front end of the supporting platform 7; a pushing plate 26 is provided above the pushing sliding roller 25, and the pushing plate 26 The pushing base 27 is fixedly connected to each other with the pushing base 27; th...
Embodiment 2
[0047] A cutter for a gypsum line coating device, which is prepared according to the following process:
[0048] 1) Take the following raw materials in parts by weight: 1 part cerium powder, 1 part samarium powder, 2 parts lanthanum powder, 2 parts graphite fiber, 3 parts tungsten powder, 5 parts molybdenum powder, 5 parts cobalt powder, 7 parts manganese powder, 30 parts of chromium powder, 90 parts of nickel powder, 500 parts of iron powder;
[0049] 2) Add cerium powder, samarium powder, lanthanum powder, graphite fiber, tungsten powder, molybdenum powder, cobalt powder and manganese powder to the stirred reactor in sequence, stir at 500rpm for 3min, then add chromium powder and nickel powder, and continue stirring at 500rpm 3min, then add iron powder, stir at 1000rpm for 5min to obtain a mixture;
[0050] 3) Preheat the furnace temperature of the electric arc furnace to 400°C, then add the mixture, heat to 1200°C, and hold for 30min; then enter the LF furnace for refining, the r...
Embodiment 3
[0053] The wear and corrosion resistance performance test of the cutter prepared in Example 2 of the present invention:
[0054] 1. The friction material of the grinding wheel is used, and the stopwatch counts for 180 seconds to detect the quality of the silicon carbide grinding wheel and the cutter to determine the wear ratio. The cutter materials are all 5mm×5mm×5mm size. See Table 1:
[0055] Table 1
[0056] Types of
[0057] 2. Salt corrosion resistance test: the cutter material prepared in Example 2 is soaked in 6% sodium chloride aqueous solution for 240 hours: the surface is very slightly corroded, and more than 99% remains bright; the area within 1% becomes gray-brown spots.
