Description
Technical field
The invention belongs to Warm Extrusion precision form new technology and the Tool and Die Technology of a kind of gear, be used for improving straight tooth column tooth
The working (machining) efficiency of wheel.
Background technology
At present, producing of most straight spur gear uses traditional cutting working method mostly, but it has very
Many defects, such as: stock utilization is low, cost is high, and working (machining) efficiency is low.Along with the development of mechanical industry and intensifying of international competition,
The raising of performance and the reduction of processing cost to gear product are had higher requirement, the especially raising of working (machining) efficiency.Cause
Extruding and the forging and molding technology of this gear are paid attention to and are developed.This type of processing method is by original traditional handicraft processing method
The stock utilization of 40% brings up to more than 70%, and the strength of gear teeth also improves 20%, and working (machining) efficiency raising about 40%, but
This type of processing method all uses single-piece production processing method, and its working (machining) efficiency needs further to be promoted.To this end, inventor proposes
A kind of extruding new method of highly-efficient processing straight spur gear.
The extruding new method of this highly-efficient processing straight spur gear be the Warm Extrusion precision form new technology with gear and
Based on Tool and Die Technology, in vertical extruder, continuously extruded shaping hollow strip straight spur gear pipe, then uses line
Continuously extruded shaping part is cut into gear finished parts by the method for cutting.This kind of method is to use continuous Warm Extrusion precision form
Technique, produces as far as possible close to the product of gear net shape, and therefore this kind of processing method not only has material-saving, energy-conservation, low cost
Deng significant advantage, and mechanical property and the processing characteristics of gear can be improved, additionally, due to use ferrous metal vertically to extrude
The continuously extruded shaping of machine, then uses linear cutter to become gear finished product, has than single-piece extrusion molding and higher add work efficiency
Rate.
In this Warm Extrusion precision progressive forming new technology and Tool and Die Technology, use Warm Extrusion precision progressive forming method
Manufacture the hollow strip straight spur gear pipe fine forge piece close to gear part shape, more traditional Precise Cold-extrusion side
Method working (machining) efficiency is high, and the surface quality and the mechanical property that obtain compared with thermal extrusion moulding method are good.In Design of Dies, use die
On put and be easy to continuously extruded shaping, facilitate feeding simultaneously, and Die Design become pre-stress combination matrix, part can be offset
Or be completely counterbalanced by the tangential stress produced during mold work, thus improve the intensity of whole die, it is possible to improve mould
Life-span, and when die inner ring produces mill an ancient egg-shaped, holed wind instrument or crackle, only need to change die inner ring, be greatly saved mold materials.Above-mentioned
New technology makes the precise extrusion molding of straight spur gear, and the mechanical property of the part being possible not only to acquisition obtains bigger proposing
Height, but also have higher production efficiency.Therefore, the extruding new method of the hollow straight spur gear of this highly-efficient processing has very
Good use value and development prospect.
Summary of the invention
The purpose of patent of the present invention is: for the problems referred to above, overcomes the material poor efficiency that straight spur gear is processed, high
Manufacturing cost and relatively low working (machining) efficiency.In ferrous metal vertical extruder, use continuous Warm Extrusion precision form, then adopt
Gear finished parts is become with linear cutter.Hollow strip straight spur gear is manufactured with continuous Warm Extrusion accurate forming method
Pipe, more traditional forming technique decreases the cutting output of rear operation, decreases the consumption of the material energy.Continuous way Warm Extrusion is accurate
Shape, the longest gear tubes fine forge piece can be squeezed out through a warm-extrusion forming, be then passed through line and cut into gear finished product
Part, more traditional single-piece extrusion forming method, it is possible to reduce manufacturing procedure, improves the working (machining) efficiency of gear further.
The technical scheme of patent of the present invention is: the present invention is the extruding new method of a kind of highly-efficient processing straight spur gear,
Including the set-up procedure of blank, continuous warm-extrusion forming process, three corresponding stages of line cutting forming process.
The set-up procedure of blank mainly includes that rod iron blanking, material softening annealing, bead blasted surfaces process technique, washing, phosphorus
Change and saponification process；Continuously Warm Extrusion process mainly includes, with the technique realizing material and being full of tooth cavity, female die of die being put, and
Use combined die, increase strength of concave mould, and die is made up of guide ring, extrusion chamber and forming cavity.Line cutting forming process master
If continuous warm-extrusion forming part is cut into more than one piece gear finished product.
Use this kind of scheme, by the gear member of the continuous once-forming longer dimension of Warm Extrusion accurate forming method, then
Line cuts final formed gear finished parts.This new technology can realize higher Gear Processing efficiency.
As a modification of the present invention, use and put on die, in ferrous metal vertical extruder by mould upwards
Warm-extrusion forming spool gear pipe fine forge piece continuously, then uses line cutting forming gear finished parts.
Use this kind of scheme, not only contribute to improve the size of straight spur gear part, form accuracy and mechanical property,
The mold use life-span, and the working (machining) efficiency of gear can be improved further.
