Description
Technical field
The present invention relates to a kind of cold forging and make technical field of processing equipment, a kind of numerical control moving cold-forming machine frequently specifically is provided.
Background technology
Automatic transmission, owing to having energy-saving and environmental protection, the advantage such as safe, comfortable, easy and simple to handle, has become the developing direction of automotive transmission.The wet clutch assembly of electrichydraulic control is that the automatic transmission such as CVT, AT realize one of important executive component of automatic reverse, clutch or gearshift, and it is mainly by clutch hub, Wet-type friction slice, form coupling sheet, splined hub, input and output shaft etc.Wherein, clutch hub is its important force transfer element, and its manufacturing technology and technological equipment are subject to the attention of each large speed changer enterprise always.
The automatic transmission industrialization of China's independent intellectual property right falls behind, and its one of the main reasons is exactly that automatic gear-box kernel component (electric liquid module, clutch assembly, planet row assembly etc.) manufacturing technology and technological equipment fall behind.This has become one of technical bottleneck of puzzlement Chinese Auto Industry development, causes that China's automatic gearbox Product Process is backward, manufacturing cost is high, technical merit is backward, and the entrucking rate is low.Particularly on the economy car of independent brand, automatic transmission entrucking rate less than 30% (is nearly all foreign capitals or joint brand! ) and accounted for dominant position at some automobile developed country automatic transmission passenger cars, in automobile as the production of the states such as U.S., Japan and Korea S., automatic transmission entrucking rate is very high, surpass 90%, even Europe has also surpassed 50%, the competitiveness that this has seriously reduced China's vehicle complete vehicle, also limited the development of China's automobile energy-saving technology, even limit to a certain extent the development of our military vehicles, badly influenced national defense safety.
The clutch hub of current automatic transmission adopts rotation forging and stamping and the technology such as cold extrusion shaped more.
The advantages such as rotation forging and stamping and the technology such as cold extrusion shaped have that shaping efficiency is high, dimensionally stable, utilization rate of raw materials are high, less energy consumption, recruitment are few, belong to the low-carbon green manufacturing technology that country encourages.Adopt the parts of this technology manufacture can be widely used in the light industry and machinery fields such as Aero-Space, automobile, engineering machinery and weaving, there are boundless market prospects.But, due to the complex structure degree of the parts of different field, manufacture the difference such as batch, its process characteristic and specification requirement differ greatly, mostly the integrated special equipment that also there is no at present this respect, be to adopt relevant separating technology manufacture, not only exists automaticity and efficiency low, quality stability and precision also are difficult to control, bad adaptability, and be unfavorable for economizing on resources and improving environment, be difficult to realize intelligence programming and integrated manufacture.
Summary of the invention
The present invention be directed to above problem, a kind of numerical control moving cold-forming machine frequently is provided, it can not only meet the manufacture of clutch in automobile automatic gear shifting hub, can be satisfied with equally the demand of the industry key components and parts such as boats and ships.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of numerical control is moving cold-forming machine frequently, comprises lathe bed, in the master cylinder on described lathe bed top, is provided with main shaft, described main shaft upper end connects cylinder pressure, described main shaft lower end connects mould bases, and the mold platform of described mould bases below is arranged with takes blame for others, and cylinder pressure is connected with frequently moving digital control system.
A kind of numerical control is the frequency modulation forming method of moving cold-forming machine frequently, comprises the following steps:
Fixing workpiece to be processed between cylinder pressure lower end in A, master cylinder and the profile of tooth punch of the upper end of taking blame for others;
B, frequently moving digital control system control hydraulic system provide variable frequency hydraulic power to master cylinder, make axially frequently moving amplitude modulation extruding workpiece to be processed of master cylinder;
C, master cylinder press to fast workpiece to be processed and start frequently moving amplitude modulation extruding, and cylinder pressure presses down pushes down workpiece, thereby workpiece to be processed is inserted in the profile of tooth punch;
D, master cylinder be moving amplitude modulation extruding workpiece frequently, is extruded onto logical tooth, and the workpiece profile of tooth forms;
E, main-cylinder stroke are return, and the cylinder pressure stroke is return, and the stroke of taking blame for others ejects, and workpiece to be processed is ejected, and process finishes, and take out workpiece.
A kind of numerical control of the present invention is moving cold-forming machine frequently, and it adopts axial force frequency modulation method axially to be shaped, and it is a swing of stack on conventional forward travel.To Axial Force Needed reduces greatly, and in each return movement swung, in fact mould breaks away from workpiece, and the stress in material is released, and lubricating oil can constantly supplement, so lubricating film improves, thereby makes axial force reduce approximately 50% left and right.
Frequently moving digital control system is controlled hydraulic circuit cylinder pressure is carried to frequency conversion pressure, makes its downward reciprocating extrusion die.
A kind of numerical control of the present invention is moving cold-forming machine frequently, and it compared with prior art has following characteristics:
(1) enlarge the range of work
Because axial force greatly reduces, axially shaping also can be applied to because of axial force excessively, and is difficult to adopt the workpiece of conventional axial extrusion process.
(2) improve dimensional accuracy
Owing to producing without radial load, thereby the radially extension of mould reduces, thereby caused the improvement of the dimensional accuracy of workpiece.In some cases, the combination of the hardening constituent of frequency modulation and best mould size and mould, can make quality improve two grades, and the reliability of process also is improved.
(3) increase die life
When the shaping external splines, the radial dilatation of mould is little, has caused increase die life.Due to frequency modulation, the power on workpiece is able to continuous Cycle-release, makes lubricating oil can obtain continuous supplementation, and this is also very favorable to improving friction.
(4) quality:
With the workpiece be shaped for other method, compare, the workpiece that this forming machine is shaped can demonstrate improvement great aspect quality.Surface of the work through flow harden all is greatly improved on wear-resisting and intensity, and through the moving extruding of repetitious frequency, the workpiece inherent strain is released simultaneously.The grade of interior external splines DIN3962 reaches the 6-7 level.
The numerical control axially variable frequently, not only can be used widely on clutch hub by the pressure-variable technology in a word, simultaneously other products as: as the moulding of axle spline, a lot of fields such as different in nature hollow element moulding.
Compared with prior art, a kind of numerical control of the present invention is moving cold-forming machine frequently, its have reasonable in design, simple in structure, the range of work wide, can improve the production precision, increase die life, improve the characteristics of workpiece product quality.
