Processing large gate blade outer arc surface and tooling design and manufacture of arc

Pieces of 22-bit board seat positioning plates 24 connected fixed. 2.7 transmission gear, transmission parts rack paid and l6 15 power head to control the tool path and speed of horizontal alignment. Feed me pieces of round pieces of l8 l7 manual hand power tool to control the amount of size (you can manually fine-tuning), power head cut off the nose milling cutter pieces 2l 2o pieces are made from the 42-Summer Eagle - Book Two # 43 Tin Chong garlic halo twilight H a HH a button ah tan cells ancient LJLJ close the eyes King World Pi {a field Mighty leisurely meal.

Gaozhicaoshi. Island drugs. q cents, milling effect. 3 arc gate blade 3.1 will be assembled cylindrical arc processing gate blade piece 1 piece 4 activities pivot leg pieces 5,[link widoczny dla zalogowanych], the connection as a whole, according to Figure I (radial gate working position) with the support bracket pieces l0 fixed and seek positive, requires arc radius allowance 1t = 20O00 stay 5-8. 3.2 will be the central axis positioning plate pieces 7 pieces of 27 were installed in the arc of the piece of Movement of pivot hole 5, the use of alignment plate 26 and pull pieces of ruler and draw needle, draw the arc of the door on both sides of processing line (rustic demand pull feet under tension in 7lcg) 3.3, respectively, the activities of the tooling support fixed pivot hinge piece 6 piece 8 piece 7 mounted on the central axis,[link widoczny dla zalogowanych], and fixed on the base parts 9. Assemble a good two-arm,[link widoczny dla zalogowanych], piece l1.12 and 13 pieces of bed (bed body power head, gearbox, feed boxes, large pallet, the pallets,[link widoczny dla zalogowanych], etc. should be fully assembled and tested prior good car.) 3.4, respectively, arc welding on the side doors on both sides adjustable positioning plates 24,[link widoczny dla zalogowanych], the short arm tooling positioning plate corresponding to the fixed seat the silk. Lifting the door frame welded to the top of the door mount manual arc and wire rope hoist shown in Fig. 3.5 installed in the bed by the body parts to find are thimble stork to draw good base line for radial gate processing, tooling parts to the central axis of rotation 7 as the center and check the plunger up and down the sides of the door with the arc line processing line is re-sets If the size of a deviation variable is the length of two arms, transferred to coincide with the processing line. 3.6 arc when the doors should be on the down milling, each row is 150 by the displacement from the positioning plate, the first knife for the rough milling, leaving 1-2 margin, the second knife is fine milling, milling to size requirements. 4 arc door design features of 4.1 processing power head tooling, milling cutter center line should be perpendicular to the direction of the tangent arc-arc door, the door can only be milling arc. Because the power head and vertical sliding body in the bed bed, so bed connection with the short arm, must have a central angle to meet the processing technology, as shown in Figure 3 requirements: it is calculated as shown in Figure 4 production 'l -jI-1 set JlL one l. 1I, Il . / T Yue Hao base connecting plate body 2. Main boom center anuran 3 Xiao Yue Department of interconnect 4. Body of British Columbia - War around three body and arm themselves and join around four dollars renovating the arm angle = 735 = 0.003586: o3 'so the bed center and the center arm offset in the manufacture of installation requirements 2 o3 angle. 4.2 Radial Gate arc in the process were due to walk the knife is the rows, the effective processing of flat cutter 150, cutter diameter of 250 (take the knife width of three-fifths of the diameter cutter to consider tool cooling Factors that 250 of the 3 = l5O) shown in Figure 5, the flatness of the processed as: sim_ = Qing = 75 = ~ o. 130375 = 0.21486oOC = o0sax2000O = 19999.86CD = oa (R) a 012 = 2o000-1999.86 = 0.14 ~ <0.15 meet product design requirements. 1. Nine contour lines arc after processing 2. Contour arc door before processing electrical coil electrical part of the design requirements of 55 rotation and horizontal milling tool path centralized operation, separate departure, stop, and can be carried forward and reverse movement. 6 6.1 Effect of the tooling process in March 1, 1999 into the first cylindrical arc leaves the door f1 processing, the original plan for one month (two shifts), the actual only a 2o days. 6.2 The factory will be processed in the factory gate blade and the threshold arc of the big group. The Yellow River Conservancy will institute, Xiaolangdi project engineering supervision bureau and other departments to a joint inspection team of experts acceptance, the cylindrical arc radius of curvature, surface roughness, roughness and other horizontal machining precision, geometry and sealing requirements items are fully meet the design standards, a through acceptance. 7 Conclusion This large gate blade cylindrical arc process in the country is the first case, practice has proved that the drawings of the technical indicators have reached the design requirements. The success of its manufacturing process, and no large cutting machine tools can not replace; it leaves for future Water arc process arc fll'7 out a new path profile, water conservancy construction in our country and all walks of life in the machining worth learning and promotion. 46
