Abstract

Provided is a noise reduction die which can reduce stamping noise during stamping. The noise reduction die comprises a striking head, an upper die spring seat, a spring guide pillar, a lower spring seat, an upper die seat, a material returning device, an upper die, a pressure plate, a spring seat and a through bolt. The upper portion of the spring seat is matched with the striking head in a contact mode, the upper portion of the upper die seat is sleeved with an inner cavity of the spring seat, the upper die seat and the upper die are connected through the through bolt, the material returning device is arranged outside the upper die, the pressure plate is arranged on the lower portion of an inner cavity of the material returning device, the upper die spring seat and the lower spring seat are arranged on the spring seat, the spring guide pillar is arranged on the upper die spring seat, and a crash pad is arranged between the upper end face of the flange edge of the spring seat and the lower end face of the flange edge of the lower spring seat. The noise reduction die is ingenious in design and convenient to produce, effectively reduces noise generated during stamping, and reduces harm of the noise to the human body.

Description

Noise reduction mould
Technical field
The utility model relates to punching die device field, relates in particular to a kind of diel of the reduction noise for NC turret punch machine.
Background technology
Existing numerical control punch die is the problem of C, D station larger noise of existence in the time of work in use, and noise is greater than 90 decibels, forms noise pollution, works for a long time and can cause damage to personnel's body and mind under this environment.Cause noise reason we be analyzed as follows: (1) dish spring part, when the resilience of dish spring, the excessive and collision of elastic force causes noise; (2) between guide pin bushing and upper bolster because the resilience of dish spring is made and is clashed into the noise that causes; (3) holding pad and counterdie (or sheet material) clash into the noise causing.
Utility model content
The utility model, for above problem, can reduce the noise reduction mould of punching press noise when a kind of punching press is provided.
The technical solution of the utility model is: comprise attacking head, patrix spring base, spring lead, lower spring cup, upper bolster, stripping attachment, patrix, holding pad, spring base and punching bolt, described spring base top contacts cooperation with described attacking head, described upper bolster top is sheathed on described spring base inner chamber, described upper bolster is connected by described punching bolt with described patrix, described stripping attachment is located at described patrix outside, described holding pad is located at the inner chamber bottom of described stripping attachment, described patrix spring base and described lower spring cup are located on described spring base, described spring lead is located on described patrix spring base, between the lower surface of the upper surface of described spring base flange and described lower spring cup flange, be provided with crash roll.
Between described patrix spring base and described lower spring cup, be at least provided with four groups of springs, described in every group, spring housing is located on described spring lead.
The lower surface of described holding pad is lower than the lower surface of described stripping attachment.
Described holding pad material is macromolecular material.
The utility model is not affecting under the prerequisite of mould self function and performance, for the problem points that produces noise, makes to reduce with the following methods noise:
(1) between spring base and lower spring cup, set up crash roll, solved strike note between the two;
(2) use spring to replace dish spring, avoid between dish spring and spring base and dish spring and dish spring between noise;
(3) holding pad uses macromolecular material to replace metal material, reduce between metal between clash into and the noise that causes, also avoid directly contacting due to metal crimp flitch and sheet material the problems such as the sheet material impression that causes simultaneously.
The utility model design is ingenious, is convenient to produce, and the noise producing while effectively reducing punching press, reduces the injury of noise to human body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the top view of Fig. 1,
Fig. 3 is the left view of Fig. 1;
In figure, 1 is attacking head, the 2nd, and patrix spring base, the 3rd, spring lead, the 4th, spring, the 5th, lower spring cup, the 6th, upper bolster, the 7th, stripping attachment, the 8th, patrix, the 9th, holding pad, the 10th, spring base, the 11st, crash roll, the 12nd, punching bolt.
Detailed description of the invention
The utility model as Figure 1-3, comprise attacking head 1, patrix spring base 2, spring lead 3, lower spring cup 5, upper bolster 6, stripping attachment 7, patrix 8, holding pad 9, spring base 10 and punching bolt 12, described spring base 10 tops contact cooperation with described attacking head 1, described upper bolster 6 tops are sheathed on described spring base 10 inner chambers, described upper bolster 6 is connected by described punching bolt 12 with described patrix 8, described stripping attachment 7 is located at described patrix 8 outsides, described holding pad 9 is located at the inner chamber bottom of described stripping attachment 7, and the lower surface of described holding pad 9 is lower than the lower surface of described stripping attachment 7, while being convenient to punching press, described holding pad 9 first touches workpiece, prevent from damaging described stripping attachment 7,
Under off working state, the top of the lower surface of described patrix 8 in described pressure plare 9 lower surfaces;
Described patrix spring base 2 is located on described spring base 10 with described lower spring cup 5, described spring lead 3 is located on described patrix spring base 2, between described patrix spring base 2 and described lower spring cup 5, be at least provided with four groups of springs 4 and described spring 4 axle centered by the axis of described spring base 10 is uniform, described in every group, spring 4 is set on described spring lead 3;
Between the lower surface of the upper surface of described spring base 10 flanges and described lower spring cup 5 flanges, be provided with crash roll 11, when slowing down punching press described in shock between spring base 10 and described lower spring cup 5, reduce noise.
For better reducing noise, described holding pad 9 uses macromolecular material to replace metal material, reduces to clash between metal and the noise that causes, also avoids directly contacting due to the described holding pad 9 of metal material and sheet material the problems such as the sheet material impression that causes simultaneously.
Can regulate de-material power by the kind that increases and decreases the quantity of described spring 4 and change described spring 4 simultaneously, avoid taking off the excessive sheet deformation problem causing of material power, also can avoid the de-too small band material problem causing of material power.
