Description
Technical field
The present invention relates to ultra-thin smart handset field, more particularly to a kind of support punching mechanism for smart mobile phone.
Background technology
The mobile phone of existing mobile phone, especially low and middle-end, its housing be largely adopt it is made of plastic.Plastic handset shell is resistance to
Mill property is poor, using cut occurs after a period of time, or even the situation such as fade.Therefore, some high-end handsets, are more and more adopted
With metal shell, for example with stainless steel, aluminium alloy or titanium alloy shell, these metal hand casings because wearability is good, and
The outward appearance of fineness can be made, is liked by consumer very much.But existing metal hand casing is limited by processing method, cost occupies
It is high not under, it is difficult to generally use.Existing metal hand casing is formed by block of metal cutting, and metal hand casing requires external portion
Simple and beautiful, below with parts part-structure it is very complicated, need to be mounted so that other parts are, it is necessary to design many buttons
Position, post position, western arc angle, height step etc., it is necessary in processing center of numerical-control machine tool if being made of whole block material cutting
For a long time, machinery is surprising precisely and more than quantity, causes cost extremely expensive for processing.
The content of the invention
The present invention provides a kind of support punching mechanism for smart mobile phone, and this is used for the support punching mechanism of smart mobile phone
It is simple to operate, it is possible to reduce it is artificial, while scrappage is reduced, production cost is correspondingly reduced, reduces cost of investment, equipment
Cost is low, and maintenance cost is low, and it also avoid the damage to workpiece without bits are taken during push broach reset.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of support punching mechanism for smart mobile phone,
Including upper mold holder, baffle plate, stripper plate and the die shoe set gradually from top to bottom, the upper mold holder lower surface has one
Vertical wedge and elastic component, the baffle plate erect with a transmission rod, for the through hole of vertical wedge insertion and lower surface with one
Straight inclined plane slide block, stripper plate have one to suppress block and 2 through holes, and being provided between the die shoe and stripper plate can be along level side
To the stamping knife of motion, the rear end of this stamping knife has a horizontal ramps sliding block, and a through hole is for upper mold holder in the stripper plate
Vertical wedge insertion, another through hole are embedded in for the vertical inclined plane slide block of baffle plate；
One installing plate is fixed on the stripper plate or die shoe, and a spring housing is loaded on push rod and is located at its mounting blocks
Between installing plate, the front-end and back-end of this push rod are respectively mounting blocks, block, and the mounting blocks other end of this push rod is fixed with one
Horizontal wedge and push rod, the preceding end in contact of the push rod and stamping knife, the vertical inclined plane slide block of the horizontal wedge and baffle plate are matched somebody with somebody
Close；
There is material spilling hole between the transmission rod is located at elastic component and suppresses block, between the stripper plate and die shoe and take off
Flitch has one to blow useless through hole above material spilling hole, and a suction nozzle is located at the side end face of stripper plate, and this suction nozzle is useless with blowing
Penetrated between through hole by passage；
The friction plate is secured by bolts in die shoe.
Further improved technical scheme is as follows in above-mentioned technical proposal：
In such scheme, the die shoe upper surface is provided with a friction plate.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1st, the present invention is used for the support punching mechanism of smart mobile phone, and its is simple to operate, it is possible to reduce and it is artificial, reduce simultaneously
Scrappage, correspondingly reduce production cost, reduce cost of investment, equipment cost is low, and maintenance cost is low, reduce investment into
This, again reduce machining processing capacity, process time highest can be reduced 95%, greatly reduce metal hand casing into
This；Secondly, when upper mold holder is descending, vertical wedge promotes horizontal ramps sliding block, so as to drive stamping knife is horizontal to move ahead, erects simultaneously
Straight inclined plane slide block is descending to promote horizontal wedge, the push rod compression spring when its thrust is more than spring tension, and suppresses block positioning work
After part, stamping knife carries out scraping operations to machined part, after the completion of, upper mold holder is up, under the thrust of spring, the push rod of push rod
Promote stamping knife to automatically reset and promote baffle plate up respectively with horizontal wedge, now suppress the pressure of block to machined part almost
It is zero, without bits are taken when push broach resets, it also avoid the damage to workpiece.
2nd, the present invention is used for the support punching mechanism of smart mobile phone, between its transmission rod is located at elastic component and suppresses block, takes off
Above material spilling hole useless through hole is blown with one with material spilling hole and stripper plate between flitch and die shoe, a suction nozzle is located at
The side end face of stripper plate, this suction nozzle and blowing are penetrated by passage between useless through hole, after stamping knife is to workpiece scraping operations, can be led to
Cross from suction nozzle ventilation body, so as to realize that will take bits caused by scraping blow down material spilling hole, avoid under the thrust of spring, push rod
Push rod promote stamping knife take the scratch considered to be worth doing to product when automatically reseting.
