Description
Technical field
The utility model belongs to hexagonal hole class part manufacture field scope, especially suitable for part manufacturing batch is small, species
It is more, it is desirable to the of a relatively high hexagonal hole part processing of precision.
Background technology
SOC.HD. cap screw with good positioning due to loosening effect, in fields such as Aeronautics and Astronautics, ship, electronics, defence
It is widely used.Because of the extensive use of soket head cap screw, so, it is necessary to ensure six in same size during hexagonal in manufacture
The uniformity and interchangeability of angle product.Therefore in such product manufacturing, to be ensured using mould.Some products were designing
In order to ensure that soket head cap screw has specificity in journey, the hexagonal hole punching die for the off-standard size for being ignorant of specification can be applied
Meet production.
Due to the particularity of factory products, that is, there is the characteristics of batch is few, and species is more, needed when manufacturing such hexagonal hole part
It is adapted to the hexagonal hole mould of different dimensions.But different product conventionally needs to use in production
The hexagonal hole mould of different size come meet produce needs, can so cause many hexagonal hole punching dies access times to be present
It is few, fail to have given play to mould to have and can be mass, the advantage such as long lifespan.
And it is this can punching plurality of specifications hexagonal hole part punching die, the processing that is provided with mould is fast, part is consistent
Property it is high, it is easy to operate the advantages that, while the hexagonal hole class part of different size can also be processed, the raising of high degree
The efficiency of production, and die manufacturing cost has been saved, reduce the manufacturing cycle of such mould.
Equivalent to conventionally processing, using when arriving a variety of hexagonal hole parts in a product, it is necessary to corresponding system
Corresponding hexagonal hole punching die is made to meet to produce needs；Using it is such a can punching plurality of specifications hexagonal hole part perforating die
Tool, it is general a set of or two sets can meet production needs.
Utility model content
The utility model proposes a kind of punching die of punching plurality of specifications hexagonal hole part, its object is to solve pin
High to mould input cost caused by the hexagonal hole part processing of small lot, multiple types, manufacturing cycle length, production task is completed
Most of moulds are in the problem of idle state afterwards.The utility model employs three kinds of replaceable structures to meet to a variety of rule
The processing of lattice hexagonal hole part：First, in terms of the clamping fixation to part, employ for different size part using special
Fixture block reaches the fixation purpose to parts to be processed, the clamping to different-diameter part so can be achieved, for different height
The part of degree is by the way of lower section is using cushion block and adjusting pad tile height, to meet the processing needs to different height part；
Secondly, the design of the punching process to part, i.e. drift employs the design structure of replaceable drift working portion, to meet pair
The punching processing of the hexagonal hole part of different specification size；Finally, it is necessary to make part from drift after hexagonal hole is completed in punching
Depart from, that is, need a back pieces device, back pieces device is corresponding with drift when selecting drift, and is used cooperatively with drift, comes
Reach back pieces effect.
The purpose of the requires of the utility model is realized by following design idea：
A kind of punching die of punching plurality of specifications hexagonal hole part, mainly including agent structure, detent mechanism, unloader

During, pull bar is pulled out, parts to be processed is being put among two locating pieces, and releasing lever handle, sliding shoe is in spring
In the presence of, two locating pieces compress parts to be processed, and are fixed, and start forcing press, and drift sweeps away, can will during backhaul
Part takes up, and when part bumps against discharging block, can split away off from drift, then take out part, work is completed.
When part height is not suitable for, cushion block is added between backing plate and part, to meet the processing of different height part.When needing to change
When another specification part is processed, corresponding locating piece is selected to be substituted into according to the appearance and size of new parts to be processed
On mould, further according to new cushion block is highly selected, finally by the hexagonal hole size dimension of new parts to be processed, select corresponding
Drift punch-pin, replace original punch-pin, and the model of discharging block is determined according to the model of punch-pin, and by new discharging
Block is substituted on mould.Treat it is above-mentioned after, you can process new parts to be processed.
Aforementioned body structure, is made up of backing plate and lower template, and both are connected by fastener, and are fixed at work
On press machine, played in mould structure connect other several mechanisms and undertake in punching course by part transmission come master
Want pressure.
Above-mentioned detent mechanism, it is made up of fixed block, sliding shoe, locating piece, bearing, pull bar, spring and handle.It is wherein fixed
Block, bearing are fixed on the body construction by fastener；Sliding shoe forms movable part with pull bar, spring, handle；Two positioning
Block is separately fixed on fixed block and sliding shoe by fastener.Play a part of fixed workpiece to be added in mold work, lead to
Cross and change locating piece to meet the clamping of different-diameter workpiece.
Above-mentioned shedding mechanism, it is made up of bearing support and discharging block, discharging block is fitted in bearing support by interference fit
On, bearing support is installed on the body construction by fastener.Bearing support is contacted to coordinate by H7/f7 gaps with sliding shoe and processed, right
Guide effect is played in the slip of sliding shoe.Played in mold work after punching press is completed, allow part to depart from the back pieces of drift and make
With.
Above-mentioned drift, it is made up of punch-pin, nut, die shank.Wherein nut and die shank can be used as common-use size part, you can system
Make a set of standard, it is convenient to exchange and repair；Punch-pin determines the size of punch-pin working end according to the hexagonal hole size of workpiece to be added,
Punch-pin position portion is made as unified just accurate, when can reach punching different size hexagonal hole, can retain die shank, nut, only logical
Cross replacing punch-pin and can reach requirement.
The utility model has the advantage of while can meet daily process requirements, reduce the manufacture week of such mould
Phase, the utilization rate of most of mould parts is improved, the locating piece only needed by changing in process, cushion block, be with punch-pin
The demand of processing different size hexagonal hole part is can reach, that is, disclosure satisfy that different height, different-diameter, different size hexagonal hole
The process requirements of part.Die cost input can be greatly lowered.
