Description
Technical field
The present invention relates to hot forging technical field of forging, specifically a kind of trimming for adapting to the hot forging of different-diameter piston is de-
Expect mechanism.
Background technique
Piston structure is similar, and specification is more.Steel piston generally uses open type hot-die forging process, different productions in forging process
Product correspond to different trimming die carrier structures.It is every to replace a kind of product, it is necessary to the synchronous forging die and trimming mould bases for replacing the product
Structure, in the replacement of trimming die carrier structure, it usually needs replacement trimming punch, three trim die, trimming stripper plate toolings.
Wherein, the design requirement of trimming stripper plate is lower, however, to ensure that intensity, eliminates hot forging when because of trimming as far as possible
Height temperate zone would generally thicken the influence that deforms, thickness, this result in the stripper plate of trimming process be lost in process of production compared with
Greatly, increase die adjustment time and manufacturing cost.Design and produce a kind of versatile piston that can be suitable for different-diameter
Trimming stripper plate mechanism generates under exactly such background.
Summary of the invention
The purpose of the present invention is to provide a kind of trimming material removing mechanisms for adapting to the hot forging of different-diameter piston, on solving
State the problem of proposing in background technique.
To achieve the above object, the invention provides the following technical scheme: a kind of adapt to cutting for different-diameter piston hot forging
Side material removing mechanism, including trimming cope plate and trimming lower template are fixed with two trimming station plates of installation, trimming in trimming lower template
It stands and trim die seat is installed on plate, trim die seat holds trim die, the interior bottom of trim die by pressing plate fixing clamp
There is piston forging vertically, the bottom of trimming cope plate is fixedly installed with transition plates, and the lower surface edge of transition plates is in rectanglar arrangement
Four groups of guiding guide posts equipped with die springs straight down are installed, the transition plates positioned at four groups of guiding guide post middle positions
Lower surface is fixedly installed with trimming punch link block, and the bottom end of trimming punch link block is connected with trimming punch, is oriented to guide post
Bottom is equipped with trimming stripper plate by bolt presses, and the bottom of trimming stripper plate offers adjustment tank, setting inside adjustment tank
There are four groups of adjustment blocks with adjustable internal control diameter.
As a further solution of the present invention: trimming cope plate is driven by the sliding block in crank press, crank
Press machine is 250T/315T using device model.
As a further solution of the present invention: the overlap of piston forging is connected on the outer diameter of trimming punch.
As a further solution of the present invention: guiding guide post and trimming stripper plate are compressed by nut, convenient between the two
Installation and removal.
As a further solution of the present invention: the adjustment tank clearance fit of adjustment block block and trimming stripper plate, in order to
Store lubricating oil, the error of compensation between the two etc..
As a further solution of the present invention: realizing that trimming de- material diameter is variable, it is meant that the diameter on stripper plate can
With adjustment, this function is realized, while guaranteeing that the intensity of trimming stripper plate is constant, reduce piston forging and trimming stripper plate is deformed
Influence, adjustment block is arranged to T-type structure, the adjustment tank on trimming stripper plate is corresponding to be also changed to T-slot, due to adjustment block
It is mounted in the T-slot of stripper plate, forms a kind of semi-surrounding structure, the purpose done so is to reduce meeting of slotting on stripper plate
Low intensive influence is dropped, to guarantee the stability of tooling.
As further scheme of the invention: adjustment block is by two bolts adjustment and is fixed on trimming stripper plate,
Die springs elastic force of the de- material active force that trimming stripper plate generates on four guiding guide posts, selects suitable mold bullet
Spring has also been assured that the range of this set trimming mould bases de- material ability, has also determined that trimming stripper plate upper setting block is adjustable
Whole range.
Compared with prior art, the beneficial effects of the present invention are: since de- material diameter is adjustable, a set of trimming mould bases,
As long as switching trimming punch and trim die, trimming stripper plate do not need to replace again, the efficiency of switching tooling is improved；
The application of the block structure of T-type adjustment simultaneously, also reduces the influence de- material to stripper plate intensity to greatest extent to a certain extent
The adjustment effect of T-type adjustment block on plate, so that the range that a set of trimming mould bases is applicable in no longer is single piston kind, but one
The piston trimming for determining diameter range can be applicable in, and the adjustability of de- material diameter increases the trimming scope of application of trimming mould bases, contracting
Casual labourer's dress changes the outfit the time, avoids unnecessary tooling material loss, has saved production cost, production efficiency has been turned up.

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment one
A kind of trimming material removing mechanism adapting to the hot forging of different-diameter piston referring to FIG. 1-2, including trimming cope plate 11 and cut
Side lower template 13, trimming cope plate 11 are driven by the sliding block in crank press, and crank press is using equipment
Model 250T/315T is fixed with two trimming station plates 12 of installation in trimming lower template 13, is equipped with trimming on trimming station plate 12
Die socket 7, trim die seat 7 hold trim die 5 by 8 fixing clamp of pressing plate, and piston forging is arranged vertically at the interior bottom of trim die 5
Part 6, the bottom of trimming cope plate 11 are fixedly installed with transition plates 1, and the lower surface edge of transition plates 1 is equipped with four in rectanglar arrangement
The guiding guide post 3 equipped with die springs of group straight down, positioned at the following table of the transition plates 1 in four groups of 3 middle positions of guiding guide post
Face is fixedly installed with trimming punch link block 2, and the bottom end of trimming punch link block 2 is connected with trimming punch 4, piston forging 6
Overlap is connected on the outer diameter of trimming punch 4, and the bottom of guiding guide post 3 is equipped with trimming stripper plate 10 by bolt presses, is led
It is compressed to guide post 3 and trimming stripper plate 10 by nut, convenient for installation and removal between the two.The bottom of trimming stripper plate 10
Adjustment tank is offered, adjustment tank is internally provided with four groups of adjustment blocks 9 with adjustable internal control diameter, 9 pieces of adjustment block and trimming
The adjustment tank clearance fit of stripper plate 10, in order to store lubricating oil, the error of compensation between the two etc..
In order to realize that trimming de- material diameter is variable, it is meant that the diameter on stripper plate is adjustable, realizes this function,
Guarantee that the intensity of trimming stripper plate 10 is constant simultaneously, the influence that piston forging 6 deforms trimming stripper plate 10 is reduced, by adjustment block
9 are arranged to T-type structure, and the adjustment tank on trimming stripper plate 10 is corresponding to be also changed to T-slot, since adjustment block 9 is mounted on de- material
In the T-slot of plate, a kind of semi-surrounding structure is formed, the purpose done so, which is to reduce the fluting on stripper plate 10, can reduce intensity
Influence, to guarantee the stability of tooling.
The working principle of the invention is: adjusting the de- material diameter that trimming stripper plate 10 controls trimming, trimming by adjusting block 9
