Abstract
The invention is concerned with the driven gear manufacture technics that is static pressure blank by numerical control hydraulic press, makes hole expansion by ring rolling machine, cone rolling swaging roller, which is for rear axle driven gear of vehicle and other plate or ring forging piece. It is: reforms the travelling table with four work-positions on the general hydraulic press, and connects with the hydraulic press become to numerical control operation system; fixes four work-positions with forging mould on the travelling table, in order to process the forging of driven gear bad pre-forge; makes upper radial hole expansion by D51-450 ring rolling machine, in order to achieve tangential distortion; uses WGZ400 numerical control cone swaging roller to rolling along the axial direction in order to achieve the axial direction distortion, get the driven gear blank correspond to finish forge by 8000KN heat drop press.
Description
Technical field
The present invention relates to sedan-chair driven-gear briquette and other dish behind a kind of motor vehicles, lopps new technique for forging.
Background technology
One, driven-gear briquette (basin tooth) forging of automobile, tractor, engineering truck adopts coal, oil heating more at present, forging hammer blocking (jumping-up, punching, die-cut gross weight, expand hole, shaping), vertical staving press is the spreading finish forging radially, the shortcoming of this technology is that 1. the forging hammer blocking is that hitting power is forged, vibration, noise height, certain danger is arranged, and work situation is poor.2. coal, oil heating, dust polluting environment.3. in the radially spreading process of driven-gear briquette staving press, the distortion of workpiece generation end face bowl-type causes roll milling wheel to cut away the metal-cored roller spreading of cylindrical side and goes out the axial overlap of endoporus, the many metals of loss; End face bowl-type distortion vestige behind finish-forging is an end face ring flute profile pit, thereby needs to increase axial chipping allowance, has reduced stock utilization.
Two, the above dish of D＞200mm, lopps forge piece all are to adopt large-scale hotdie forging press or the hot die forming of hammer class forging press.Its shortcoming is: 1, because hot forging platen class part contact area is big.Therefore, need Forging Technology power big, the equipment needed thereby tonnage is big, equipment volume is big; Not only equipment investment is big, and the investment of required workshop building is also big.2, the tonnage because of equipment is big, and consumed power is big, so power consumption is big.3, the forging impulsive force is big, and vibration is strong, noise is big.4, hot forging overlap, punching recess are all big, and stock utilization is low.
Summary of the invention
The objective of the invention is to provide a kind of driven-gear briquette, reach dish, circular piece new technique for forging.Utilize four station numerically controlled hydraulic press quasi static pressure bases, Ring Rolling Machine reaming, awl roller rivet bucker processing driven gear new technology.1, on a general hydraulic press, the workbench that moves that transformation can be adorned four stations combines as a whole with hydraulic press and becomes the numerical control operating system and link.2, four station forging molds are installed on travelling table, are carried out prefabricated continuous forging driven-gear briquette.3, adopt radially reaming on the Ring Rolling Machine, tangential deformation is rolling.4, adopt numerical control awl roller rivet bucker with the hotdie forging press finish forge driven-gear briquette more than the axially rolled form replacement 80000KN.
Owing to adopted the technical program: 1, workpiece non-trimming in the spreading operation of rolling, micron order forge that chipping allowance is little, tolerance is little, save material, and equipment does not have that noise is forged in impact, friction, nothing, the time is short, work efficiency is high.2, WGZH400 awl roller rivet bucker power and equipment volume all are far smaller than the power and the volume of 8000 tons of hot die forming forcing presses or 10 tons of forging hammers.Therefore equipment, factory building and distribution investment are low.3, new technology adopts quasi static pressure to forge, and material is heated to be electric furnace, cooling water is a cycling use of water, and factory does not have useless cigarette, no waste water, noiselessness discharging, the vibration of no impulsive force, and forging or oxide skin are not splashed and hurted sb.'s feelings, and work situation is good.4, because the new technology investment in fixed assets is low, forging and pressing process non-trimming, plant capacity is little, factors such as operating efficiency height.Reach energy-conservation 60%, economize material 10%, the corresponding production cost that reduced.
Description of drawings
Below in conjunction with accompanying drawing invention is further described.
Fig. 1 is a process chart of the present invention.
The specific embodiment
Adopt four station numerical control operating platforms to carry out program control four the station motions of finishing.Realize hydraulic press quasi static pressure base, move up and down and align heated parts and in mould, carry out quasi static pressure and forge moved cross beam speed of working stroke 20-25mm/S when operating cylinder drives moved cross beam in working order down.Station 1 jumping-up, workpiece changes station 2 rapidly over to, and moved cross beam is under the oil cylinder effect, and back and forth movement is once finished the punching operation, and work changes station 3 over to, and program is finished the cut-out gross weight, changes station 4 over to and finishes bloated hole of blank and shaping.Be transferred to reaming on the D51-450 Ring Rolling Machine then, change on the WGHZ400 numerical control awl roller rivet bucker and carry out smart tooth blank molding.Its principle: the blank after the reaming is packed in the die, workbench is delivered to workpiece with two rolls and is contacted the rotation of motor drives main shaft under the rising migration of oil cylinder, roll with the blank contact friction generation rotation of being obstructed, workpiece is carried out finish rolling tooth blank molding.
