Description
Technical field
The present invention relates to stamping die technical fields, and in particular to a kind of low noise stamping die.
Background technique
In the manufacturing, punch process is kind of a relatively conventional manufacturing process, and production efficiency is higher.When punch process
It needs to use punching machine and stamping die, is wherein commonly progressive die in stamping die, completed by continuous punching press complex
The punch process of part.
But using the punch process of the prior art, there is for a long time an open question always: when punch process by
In there are the impacts of formed punch and flitch, the noise generated is quite big, can seriously affect operator and surrounding people in factory
Health.If carrying out punching press in the press workshop being specially arranged, since press machine is more, caused by noise more
Greatly, negative effect will also result in for the ambient enviroment other than workshop.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of low noise stamping die, it is intended to noise when punching press is reduced, to protect
Protect the health of operator and surrounding people.Specific technical solution is as follows:
A kind of low noise stamping die, including upper die holder, lower die holder are respectively arranged with and the upper die holder on the upper die holder
Punch-pin, the stripper with the up and down connection of the upper die holder being fixedly connected, are provided between the stripper and upper die holder
It pushes stripper to make the elastic element of discharging movement when for discharging, is provided on the stripper for passing through punch
Dumping pit is provided with cavity plate on the lower die holder, and the cavity plate is fixedly connected on the die block of the lower die holder, described
The lower end of dumping pit is provided with the elastic noise reduction circle for surrounding the punch, and the lower end surface of the elasticity noise reduction circle is rushing
Upper flat face when pressure with charging flitch touches.
In above-mentioned technical proposal, by the way that elastic noise reduction circle is arranged around punch, its is convex when can make punching press
When stamping head is with charging flitch collision the impulsive sound that is given out into surrounding air surrounded by elastic noise reduction circle, it is besieged
The sound attenuation hole that impulsive sound passes through on elastic noise reduction circle realizes noise alleviation, so that impulsive sound when reducing punching press is to ring around
It is influenced caused by border.
As a further refinement of the present invention, being located at the surrounding of the cavity plate in the upper surface of the die block
Position offers annular groove, and the upper surface of the flexible noise reduction ring of setting in the annular groove, the elasticity noise reduction ring is rushing
It is in contact when pressure with the lower plane of charging flitch.
The above-mentioned surrounding in cavity plate is arranged elastic noise reduction ring and equally plays the role of reducing punching press noise.
As to further improvement of the invention, the surrounding position of the lower end surface of the stripper is provided with the first bullet
Property noise reduction frame, upper flat face of the lower end surface of the first elastic noise reduction frame in punching press with charging flitch touch.
Likewise, be provided with the second elastic noise reduction frame in the surrounding position of the upper surface of the die block, described the
The upper surface of two elastic noise reduction frames is in contact in punching press with the lower plane of charging flitch.
The first elasticity noise reduction of lower end surface surrounding frame of above-mentioned stripper, the second elasticity of upper surface surrounding of die block disappear
The setting of sound frame can make the major part of the impulsive sound passed out when punching press by charging flitch be closed in elasticity and disappear
In sound frame, and noise alleviation is realized by the sound attenuation hole on elastic noise reduction frame, thus impact when further reduced punching press
Sound is influenced caused by ambient enviroment.
In order to further increase erasure effect, the side surrounding of the stripper, the upper surface of the stripper are sticked
There is abatvoix.
Likewise, the side surrounding of the die block has sticked abatvoix.
As a preferred solution of the present invention, the elastic noise reduction circle is the pore type elasticity noise reduction circle that gathers, and the elasticity disappears

The decaying of micropore realization sound；Elastic noise reduction circle, elastic noise reduction ring, elastic noise reduction frame and abatvoix have the work of sound absorption simultaneously
With the good absorption of sound wave progress that can will be transmitted by feeding flitch, stripper and die block.
The beneficial effects of the present invention are:
First, a kind of low noise stamping die of the invention can be with by the way that elastic noise reduction circle is arranged around punch
So that when punching press its punch and when charging flitch collision the impulsive sound that is given out into surrounding air by elastic noise reduction circle
It is surrounded, the sound attenuation hole that besieged impulsive sound passes through on elastic noise reduction circle realizes noise alleviation, thus when reducing punching press
Impulsive sound influenced caused by ambient enviroment.
Second, a kind of low noise stamping die of the invention is arranged elastic noise reduction ring in the surrounding of cavity plate and equally plays drop
The effect of low punching press noise.
Third, a kind of low noise stamping die of the invention, the elastic noise reduction frame of the lower end surface surrounding first of stripper, cavity plate are solid
The setting of the elastic noise reduction frame of the upper surface surrounding second of fixed board, can make the impact passed out when punching press by feeding flitch
The major part of sound is closed in elastic noise reduction frame, and realizes noise alleviation by the sound attenuation hole on elastic noise reduction frame, from
And it further reduced impulsive sound influence caused by ambient enviroment when punching press.
4th, in the surrounding of punch elastic noise reduction circle is arranged, simultaneously recessed in a kind of low noise stamping die of the invention
Elastic noise reduction ring is arranged in the surrounding of mould, realizes first order noise reduction；In the elastic noise reduction of lower end surface surrounding setting first of stripper
Frame, simultaneously in the elastic noise reduction frame of the upper surface surrounding setting of die block second, realize second level noise reduction；Stripper and recessed
The setting of abatvoix in mould fixed plate, realizes third level noise reduction.The combination of above-mentioned three can play the noise reduction mutually cooperateed with
Effect, so as to achieve the purpose that reduce punching press noise by a relatively large margin.
5th, a kind of low noise stamping die of the invention, elastic noise reduction circle, elastic noise reduction ring, elastic noise reduction frame are close
Cloth pore type structure, when punching press, be closed in elastic noise reduction circle, elastic noise reduction ring or elastic noise reduction frame impact sound wave pass through it is close
The micropore of cloth realizes the decaying of sound；Elastic noise reduction circle, elastic noise reduction ring, elastic noise reduction frame and abatvoix have sound absorption simultaneously
Effect, can will carry out good absorption by the sound wave of charging flitch, stripper and die block transmitting.
