The present invention relates to CVT gearbox V-type belt wheel axle, particularly relate to a kind of CVT automatic gear-box V-type belt wheel axle finish forge plastic forming technique.
Background technology
CVT gearbox is exactly do not have clearly concrete gear, similar automatic gear-box in operation, but the change of speed ratio is but different from the trip stop process of automatic gear-box, but continuous print, therefore power transmission is lasting and smooth and easy.V-type belt wheel axle is that CVT gearbox is used for transmitting motion and turning round short mechanical key parts, and its inherent quality and precision directly affect the total quality of gearbox.China Intellectual Property Office discloses CN201110416697.7 driving belt pulley shaft, it mainly comprises input and band wheel face, input is arranged on the rear portion of band wheel face, front portion with wheel face is belt wheel construction section, the front portion of belt wheel construction section is belt wheel control section, and the diameter of belt wheel construction section is greater than belt wheel control section, and on the end face of belt wheel construction section, be evenly equipped with oil circuit mouth, belt wheel control section is provided with and oil circuit groove, the position of described oil circuit groove coordinates with the position of oil circuit mouth.Oil circuit mouth is arranged on the end face of belt wheel construction section by it, thus decreases the length of belt wheel control section, and then reduces the length of whole driving belt pulley shaft.At present both at home and abroad manufacturing firm all adopts following explained hereafter: 1. and blanking → heating (1100 ~ 1150 DEG C) → pneumatic hammer freely pulls out → and gathering stock is shaping → heat treatment → machine cut Gear shape process one by one, this production technology process complexity.Effect is very low, and the production cycle is longer, and production cost is high, and difficult quality guarantee.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, mainly solve existing conventional machining process, machine tool drops into more, machining wastes metal material, the labor productivity low production cycle is long, the technical problem that processing cost is high, adopts warm cold compound finish forge plastic forming technology, provides a kind of CVT automatic gear-box V-type belt wheel axle finish forge plastic forming technique.
The present invention is achieved by the following technical solution:
CVT automatic gear-box V-type belt wheel axle finish forge plastic forming technique, comprises the following steps:
1. warm forging plastic forming: solid cylindrical metal stock is heated to forging temperature, die forging goes out the input of frustum cone structure, belt wheel and external diameter and to taper off the cylindrical shank blank of trend, the angle that the band wheel face of described belt wheel and horizontal plane are formed is 11 °, and the another side of described input peripheral pulleys is provided with the round bump of band external tooth;
2. process annealing, Vehicle Processing: remove surperficial overlap, burr, ball blast, phosphatization, saponification process, tube reducing is processed: push the forging shank diameter tube reducing again after finishing to cold, thus reach dimensional requirement;
3. cold to push finishing shaping: push finishing with the profile of tooth of tooth die to the round bump of band external tooth is cold, cold-finish is the forging of profile of tooth without the need to following process.
Described warm forging moulding process comprises a, fracture: intercept metal bar; B, base ball blast: to metal bar sizing scale, turning, end chamfer, ball blast: blank is put into shot-blasting machine and carries out surface sand-blasting; C, coating: above-mentioned metal bar is heated to 150-200 DEG C, rare graphite soaks, and carries out face coat; Forward extrusion after d, heating: the blank good by above-mentioned coating, is heated to 800-900 DEG C and puts into die, extrude the upper surface of blank, makes bar becomes diameter, length differs three sections of column type bars and the changeover portion between them; E, jumping-up extrude: jumping-up die put into immediately by the blank of forward extrusion having been got well, and in the mold cavity closed, carry out jumping-up extruding, form two head rod portions and telophragma portion to blank; F, preformed forward extrusion: in the mold cavity closed, blank is extruded, form the input of frustum cone structure, belt wheel and external diameter to taper off the cylindrical shank blank of trend, the angle that the band wheel face of described belt wheel and horizontal plane are formed is 11 °, and the another side of described input peripheral pulleys is provided with the round bump of band external tooth.
The present invention compared with prior art has following beneficial effect:
The present invention produce constant product quality, intensity is large, density is high, shock resistance, adopt finish forge technology, decrease the substantial contribution adopting the machine tooling flank of tooth to bring to drop into, production effect is high, save raw material, after instead of forge hot, a large amount of processing method adopting machine tooling, can meet Product Precision requirement, production cycle and manufacturing cost can be shortened again, also meet the trend of world today's development of manufacturing simultaneously.
