Description
Technical field
The present invention relates to the cold punching technology field of automobile metal plate work, it is related to a kind of mould structure of shaping in deburring, tool
Body says to be exactly the molding die and forming method for being used for wheel cover of automobile outside plate and C column inner panel component.
Background technique
Automobile market competition increasingly sharpens, and how to be effectively reduced increased costs competitiveness, is always that enterprise considers emphatically
Content.There is a large amount of metal plate punching part in body of a motor car part, the cost of raw material, processing and manufacturing expense account in vehicle body cost
Bigger specific gravity.Under market environment with keen competition, the cost of raw material and processing and manufacturing of metal plate punching part is effectively reduced
Expense is the important dimension of cost control.
According to the technological level that current domestic automobile produces, in conjunction with specific production experience, merging Element Design is
It is a kind of to improve stock utilization, reduce tooling development cost and fabricate the effective means taken.But by the separation of script
Component implements component molding, and urgent need will be provided for molding mold and corresponding moulding process, such as four sequence of die procedure
Problem is also following.For so-called four sequence of die procedure for 5 process in the prior art, i.e. Fig. 1 is wheel cover
Outside plate and C column inner panel component schematic diagram are that will take turns hood panel and C column inner panel is individually independently formed by mold and welded again in the prior art
It connects in succession.According to the moulding of this part, sheet metal component quality requirement, the in-process of traditional dies has: OP10 (process 10): DR
(drawing)；OP20 (process 20): TR (deburring)+CTR (side deburring)+PI (punching)+CPI (side punching)+RST (lower shaping)；
OP30 (process 30): TR (deburring)+PI (punching)+CPI (side punching)；OP40 (process 40): FL (flange)+RST (lower shaping)+
RST (UP) (upper shaping)；OP50 (process 50): TR (deburring)+CTR (side deburring)+PI (punching)+SEP (separation) totally 5 sequence.It adopts
With conventional 5 sequence molding dies and forming method, although solving wheel hood panel and C column inner panel is individually independently formed again by mold
The problem although scheme of welded connecting is solved the problems, such as first to form and be welded again, more than existing mold increase, process.
Summary of the invention
While top priority of the invention is to provide one kind convenient for simplifying molding procedure, it is ensured that outside the wheel cover of Forming Quality
Shaping mould in the deburring of plate and C column inner panel component.
To achieve the above object, the technical solution adopted is that: it is a kind of wheel hood panel and C column inner panel component deburring on shaping
Mold, including upper and lower die holder,

Position, retainer core stroke is completed at this time, is in pier death situation state；
Process 3003: when upper die holder continues to move downward, binder core model 30 is done to be moved back up relatively, on lower die holder
Deburring punch-pin 50 and upper die holder on deburring cavity plate 60 cooperation to upper process part processing A implement deburring, until process part processing on deburring arrive
Position；
Process 3004: after upper shaping, trimming process step content are fully completed, upper die holder drives binder core model 30 to return upwards
Cheng Yundong, retainer core model 10 rise this process part processing under the support of pressure source, are convenient for pickup.
Molding die includes the mold for forming left and right component simultaneously.
The present invention will be further explained below with reference to the attached drawings.
Before work: upper shaping cutter block 40 is fixed on lower die holder；Deburring punch-pin 50 is fixed on lower die holder；Deburring cavity plate 60 is fixed
On upper die holder, moved with upper die holder；Retainer core model 10 is moved by the core model driving unit 20 that nitrogen cylinder is constituted,
It carries out moving accurate guiding by 14 upper limit guide groove 141 of guide sliding base, inner guiding post 15；Binder core model 30 passes through upper mold nitrogen cylinder pressure
Power source is moved, and carries out moving accurate guiding by upper mold guide plate, upper mold inner guiding post；Upper process part processing A passes through retainer core model 10
Local profile, positioning pin 11, positioning plate 12 carry out stable initial alignment.
In work: upper process part processing A is on retainer core model 10 after stable position, and binder core model 30 is in upper die holder, upper mold nitrogen
Under the driving of cylinder, start to move downward；After moving 10mm, binder core model 30 is contacted with retainer core model 10, and is gradually compressed
Process part processing A；After moving 5mm, binder core model 30 is contacted with upper shaping cutter block 40, starts upper re-shaping exercise；After moving 30mm, retainer
10 movement travel of core model terminates, be in pier death situation state, upper shaping end of text, at this time the nitrogen cylinder on binder core model 30 start by
Compression；After moving 7mm, deburring cavity plate 60, deburring punch-pin 50 start to contact, and deburring content starts；After moving 8mm, waste material cutting,
Deburring end of text.Upper die holder, binder core model 30 start backhaul, move upwards, retainer core model 10 is in core model driving unit 20
Driving under, this process part processing is held up into 50mm, action terminates.
