Abstract
The utility model relates to an automobile besides-star wheel forging die structure, which comprises an upper model core and a lower model core, and is characterized in that the upper model core is provided with a surplus material flash groove, the surplus material flash groove is arranged on the line contact of the outer surface of the upper model core and a formed product, the height of the surplus material flash groove is 10mm, and the depth of the surplus material flash groove is 1mm. According to the automobile besides-star wheel forging die structure provided by the utility model, a rag cutting process or a weighing process through precise computation does not need to be added, surplus waste burrs formed directly by a blank are taken down, so the requirement on sawing material is not very high, manpower and material resources are saved, the production efficiency is improved, and the production cost is reduced.
Description
Technical field
The utility model relates to the automobile metal parts and forges processing technique field, specifically just relates to a kind of automobile out star wheel forging mold structure.
Background technology
At present; Various car transmissions all adopt the drive disk assembly of out star wheel as key; Out star wheel is the critical piece of truck drive shaft, it with engine spread out of the moment of torsion that comes equably constant-speed transmission give driving wheel, take place when out star wheel also will satisfy wheel hop simultaneously stressed, turn to specification requirement such as deviation; The work force-bearing situation is extremely complicated, and the state of out star wheel directly influences security, the reliability and stability of vehicle transmission in the motion.Along with developing rapidly of automobile industry, the market demand of various auto parts and components enlarges day by day, and how rapidly and efficiently a large amount of manufacturing automobile out star wheel is a commercial production difficult problem of being badly in need of solution.
The out star wheel product belongs to a glass axial workpiece; Its shape is more elongated, and generally between 3.5～4, the diameter of axostylus axostyle and length are than between 3～3.5 for cup shaft diameter ratio; Elongated characteristic impels metal flow wayward; Especially the end moulding of axle difficulty relatively, required precision is high, and metal flow reaches specification requirement, and to be difficult to control percent defective higher to the end of axle.
Carry out traditionally in the automobile out star wheel excellent suitability for press forming process; Because raw material often heavily have unnecessary material than final products; But in carrying out the finish-forging forming process; Do not leave the space of flowing between the patrix core of mould and the counterdie core, solve the method that excess stock flows or be to adopt the open die forging, impressing forging Forging Technology, make unnecessary raw material freely overflow the formation overlap to unnecessary raw material; Be when adopting inaccessible hot die forming technology, the blanking stage just accurate calculate to weigh obtain the raw material identical with product weight.Utilize the open die forging, impressing forging Forging Technology need increase the deflashing operation, the waste machinery equipment increases manpower and materials and has strengthened production cost.Utilize inaccessible hot die forming technology to calculate to weigh that to obtain the raw material calculation control identical with product weight complicated, stability is not enough, mould is had a negative impact, and increased manual work and equipment cost.
Summary of the invention
The utility model technical problem to be solved provides a kind of automobile out star wheel forging mold structure; It has flash groove on the patrix core; Unnecessary waste material flows directly in the flash groove, does not need preorder weigh operation and follow-up excision overlap operation, directly just can take off waste material.Technical scheme
A kind of automobile out star wheel forging mold structure, it comprises patrix core, counterdie die cavity, it is characterized in that: have the excess stock flash groove on the said patrix core, the excess stock flash groove is opened in patrix core outer surface and formed product line contact position.
The high 10mm of said excess stock flash groove, dark 1mm.
Beneficial effect
The automobile out star wheel forging mold structure that adopts the utility model to provide; Need not increase excision overlap operation perhaps through closely calculating the operation of weighing, blank is the unnecessary waste material burr of formation automatically, takes off easily to get final product; It is not very high like this saw material being required; Both save manpower and materials, improved the efficient of producing again, reduced production cost.
Description of drawings
Accompanying drawing 1 is the utility model automobile out star wheel forging mold structural representation
The specific embodiment
A kind of automobile out star wheel forging mold structure; It comprises patrix core 1, counterdie die cavity 2, wherein, has the excess stock flash groove on the said patrix core 1; The excess stock flash groove is opened in patrix core 1 outer surface and formed product line contact position; Make the excess stock can flow therein, the high 10mm of said excess stock flash groove, dark 1mm.
To pass through the automobile out star wheel forging of blocking; Put into finish-forging compound extrusion forming mould counterdie die cavity 2; Finish-forging patrix core 1 stretches into the counterdie die cavity and forms the sealing shaping under the hotdie forging press effect; Normal blank is just in time filled full die cavity and can not formed unnecessary raw material; Have only the material of blank beyond last tolerance 1/3rd to form unnecessary raw material, unnecessary raw material can flow in the excess stock flash groove and form burr, and the back patrix core 1 that is shaped drives the rollback that makes progress down at hotdie forging press; Since the waste material in the excess stock flash groove be shaped after product be that line contacts under the hotdie forging press effect waste material in the excess stock flash groove and very easily separates with product in the counterdie die cavity 2; Product is stayed in the counterdie die cavity 2, and waste material is stayed in the excess stock flash groove and upwards separated with patrix core 1, and artificial then excess stock is taken out reclaimed.Utilize the described automobile out star wheel forging mold of the utility model new construction need not increase excision overlap operation or the tight operation of weighing of calculating of process; The material of blank beyond last tolerance 1/3rd forms unnecessary waste material burr; Take off and get final product, and simple in structure, both saved manpower and materials; Improve the efficient of producing again, reduced production cost.
Claims (2)
