Description
Technical field
The invention belongs to flat tube processing technique field, more particularly, to a kind of double disjunctor pipe reducing shaping die.
Background technology
China's evaporator for motor vehicle air conditioner is more at present adds the parts such as cooling radiating fin brazed with aluminum alloy porous flat pipe
Composition, and the structure of evaporator and condenser is essentially identical, difference is that simply length is more shorter, and thickness is thinner, flat
The hole count of pipe is some more, and size is more compact.It is arranged in parallel that assembling mode is generally two flat tubes, to cool down radiating fin soldering company
Connect, in assembling, cooperation to each part requires all very high, while when being combined into parallel two combs to single flat tube, adds
Installation time requires also very high to assembly technology.
In order to overcome above mentioned problem, evaporator manufacturer is answered, with dropping this requirement, to occur by continuous technological innovation in recent years
Two independent flat tubes are combined, a kind of double disjunctor pipe suitable for A/C evaporator is have developed, can effectively carry
High efficiency of assembling, still, the problem of thus causing, which is that there is presently no ripe and efficient equipment, to complete double disjunctor pipe
Necking down process, the necking down process of double disjunctor pipe are completed by manual operation mostly, and efficiency is low, can not adapt to industrial metaplasia
Production, and the equipment that double disjunctor pipe necking down process can be completed for some, the symmetry that it is processed are poor, defect rate compared with
Height, can not large scale investment production.
The content of the invention
It is an object of the invention to provide a kind of double disjunctor pipe reducing shaping die, and a necking is carried out to double disjunctor pipe
Shaping so that product has good symmetry and uniformity.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of double disjunctor pipe necking forming
Mould, including upper die component and lower mold assemblies, upper die component include upper bolster and are fixed on the cope plate of upper bolster, upper bolster and
Cylinders connect, and lower mold assemblies include die shoe, are fixed on the lower template and lower mold fixed plate of die shoe, and cope plate is provided with energy
The positioning guide column of lower mold fixed plate is enough inserted, two necking briquettings, two necking briquetting lower ends point are oppositely arranged on cope plate
Inclined-plane that She You be not relative, reducing device is respectively equipped with lower template both sides, and reducing device includes reducing die fixed plate and run through
The reducing die of reducing die fixed plate, the groove that reducing die is provided with and necking briquetting lower end shape is engaged, is arranged on reducing die
The back-moving spring of reducing die fixed plate can be withstood on, is pushed in upper die component by the process of necking briquetting lower end insertion reducing die
In, by two reducing die synchronization relative motions of slope driving on necking briquetting, necking is synchronized to double disjunctor pipe.
Preferably, it is provided with cope plate to the double stamping forming drift of disjunctor pipe, drift upper end connects with cylinder.
Preferably, a de- material block is connected on upper bolster, de- material block both sides are provided with the chute slided along necking briquetting, de-
Spring is set between material block and upper bolster, de- material block is determined the double disjunctor pipe for being placed on lower template by the elastic force of spring
Position and compression, described drift lower end passes from de- material block.
Preferably, connected between described de- material block and upper bolster by de- material block connecting rod, de- material block connecting rod one end is fixed
On de- material block, the other end is plugged in hole corresponding to upper bolster through cope plate activity.
Preferably, the imitation-shaped groove that the bottom of the de- material block is provided with and double disjunctor pipe coordinates.
Preferably, cylinder contiguous block is provided with upper bolster.
Preferably, described reducing die is provided with necking moulded board.
Preferably, contour cylinder is arranged on described reducing die, contour cylinder can pass through reducing die fixed plate, described reset
Spring is set on contour cylinder.
Described necking briquetting is movably arranged in cope plate, and is provided with upper bolster to move up and down necking briquetting
Adjustment mechanism, the adjustment mechanism includes adjustable plate, adjusting nut and clamp nut, and adjusting nut is through the regulation on adjustable plate
It is screwed in behind hole in the screw on necking briquetting top, after clamp nut is screwed in the screw of adjustable plate, its lower end withstands on necking pressure
The top of block is to fix necking briquetting.
Compared with prior art, the beneficial effects of the invention are as follows：
First, the present invention is engaged by the groove on necking briquetting and reducing die, is moved using slope driving reducing die, is protected
Demonstrate,proved two reducing dies can synchronizing moving, and there is same displacement so that double disjunctor pipe has in necking
Preferable uniformity, in addition, the process need not reduce the power consumption of processing by power is additionally provided.
Second, the de- material block in the present invention not only acts as the effect of workpiece pressing, and can also play de- material and positioning
Effect, during drift is withdrawn, workpiece is easily taken up into deformation, and de- material block can be when drift be withdrawn, compression work
Part prevents its deformation；De- material block bottom is provided with the imitation-shaped groove for accommodating double disjunctor pipe, and the elastic force that spring can be relied on downward exists
Before the double disjunctor pipe of punch. contact, double disjunctor pipe is positioned；Because de- material block is provided with chute, therefore, in spring bullet
When power acts on lower slider, vertical direction can be kept, ensureing the imitation-shaped groove of de- material block accurately can determine double disjunctor pipe
Position.
3rd, the present invention in double disjunctor pipe necking length adjustment can by adjustment mechanism control necking briquetting under
The length that cope plate is stretched out at end is realized, when needing to lengthen necking length, can screw adjusting nut, by adjusting nut and
Screw thread between necking briquetting coordinates so that necking briquetting moves down, that is, increases the length of necking briquetting lower end insertion reducing die
Degree, promote reducing die to move bigger distance, lengthen the length of necking, then screw clamp nut again, prevent necking briquetting to
On altered；Conversely, when needing to reduce necking length, clamp nut is first unclamped, then reversely screws adjusting nut, drives necking pressure
Block moves up, and reduces the length of necking briquetting insertion reducing die, finally screws clamp nut.
4th, the positioning between upper bolster and die shoe is completed by positioning guide column, is so advantageous to fast in more mold exchange
Quick-mounting plays fast positioning with ensureing precision after mold changing with mould.
5th, the present invention can realize automated production to double disjunctor pipe with one-shot forming, raw relative to current craft
Production or Semi-automatic device production, production efficiency of the invention can improve more than 10 times.
