Abstract
The invention discloses a kind of die-cut indeformable production technology of sponge elastomer, by sponge elastomer needs the shaped perimeters line of the product of punched shaping resolve into a plurality of line, it is carved into respectively after curved section and straightway etc. are broken up in different upper cutting dies, the feed direction of coastal for upper cutting die continuous elastomer is arranged successively, so sponge elastomer is carried out substep the most die-cut after obtain required product.Present invention process effectively controls the deformability of die-cut of sponge elastomer and cross cutting dimensional tolerance within 0.3mm, improves conforming product rate.
Description
Technical field
The present invention relates to a kind of die-cut indeformable production technology of sponge elastomer.
Background technology
The method of die cutting sponge elastomer mainly obtains required according to consumer product shape direct die sinking stamp in the market
Product.But because sponge elastomer itself is the most soft, when its height is at 5mm or more than 5mm, sponge elastomer is in punching
Being affected by molding when cutting, inside and outside its mould, pressure experienced is inconsistent, and product will deform, and causes die-cut one-tenth ' C ' shape
Or upper and lower skewed, and cross cutting dimensional tolerance is generally at more than 1mm, fraction defective is higher.
Summary of the invention
It is an object of the invention to provide a kind of die cutting sponge elastomer and die-cut after the production work that will not be deformed of product
Skill.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of die-cut indeformable production technology of sponge elastomer, described production technology comprises the following steps:
(1) get the raw materials ready and cut: the sponge elastomer needed for preparatory technology is some, cuts required width by product size；
(2) set of molds is prepared: described set of molds includes multiple mould arranged successively along the feed direction of described sponge elastomer, often
Individual described mould all includes the lower mold of cutting die and the described corresponding matched moulds of upper cutting die, and described upper cutting die offers the first location
Hole, described lower mold is provided with inserts the alignment pin in described first hole, location for correspondence；
The perimeter line that described sponge elastomer needs the shape of punched shaping resolves into line group, and described line group includes a plurality of line, will
A plurality of described line is carved in multiple described upper cutting die respectively, selects different rushing according to the thickness of described sponge elastomer with hardness
Cutter, and embed in a plurality of described line trend respectively with the identical described stamping knife of moving towards of a plurality of described line；
(3) hole, die-cut location: punch out the second hole, location for allowing described alignment pin correspondence insert on described sponge elastomer；
(4) punching and shaping: by described sponge elastomer along described feed direction transmission, described sponge elastomer is respectively through described mould
Multiple described mould in tool group, is gone out a plurality of described line successively, and the combination of a plurality of described line forms described sponge elastomer and needs
Shape to be rushed out.
Preferably, described line group includes circle, curved section and straightway.
Preferably, described stamping knife is peak cutter or one side cutter, the angular range of the knife edge of described stamping knife 30 ° to 65 ° it
Between.
It is highly preferred that the thickness of described stamping knife is between 0.5mm to 1.8mm, the height of described stamping knife is at 22mm extremely
Between 30mm.
It is highly preferred that be equipped with between lower surface and the described knife edge being provided thereon of upper cutting die described in each described mould
Elastic insert.
Preferably, the thickness of described sponge elastomer is not less than 5mm, and density is 10～300kg/m3Between.
Preferably, described sponge elastomer includes spongiosum, glue-line, is attached at described spongiosum by described glue-line
The release layer of both side surface.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that one sponge of the present invention
The die-cut indeformable production technology of elastomer, by needing the product perimeter line of punched shaping to resolve into many by sponge elastomer
Bar line group, is carved into circle, curved section and the straightway in described a plurality of line group in different upper cutting dies, respectively by upper cutting die edge
The feed direction of sponge elastomer is arranged successively, by obtaining required product after line group continuous cutting a plurality of to sponge elastomer,
Effectively control the deformability of die-cut of sponge elastomer and cross cutting dimensional tolerance within 0.3mm, improve product qualified
Rate.
Detailed description of the invention
Below technical scheme is further elaborated.
Above-mentioned a kind of die-cut indeformable production technology of sponge elastomer, comprises the following steps:
(1) get the raw materials ready and cut: the sponge elastomer needed for preparatory technology is some, and in the present embodiment, this sponge elastomer includes sponge
Body, glue-line, it is attached at the release layer of spongiosum both side surface by glue-line.The thickness of this sponge elastomer is not less than
5mm, density is 10～300kg/m3Between.This sponge elastomer is cut out required width by the size according to product.
(2) set of molds is prepared: this set of molds includes multiple mould arranged successively along the feed direction of sponge elastomer, often
Individual mould all includes the lower mold of cutting die matched moulds corresponding with cutting die on this, and this offers on cutting die the first hole, location, lower mold
On be then provided with for correspondence insert this first location hole in alignment pin；
The perimeter line that above-mentioned sponge elastomer needs the product of punched shaping resolves into line group.This line group includes a plurality of line, wherein
There are circle, curved section and straightway etc..A plurality of line is carved in multiple upper cutting die respectively, and according to sponge elastomer hardness and thickness
The different stamping knife of different choice of degree, and embed in a plurality of line trend respectively with the identical stamping knife of moving towards of a plurality of line.
Where like first a plurality of line being combined and the line after combination is carved in different upper cutting dies, respectively to subtract
Go up the number of cutting die less.It should be noted that and connected difform curve is carved in different upper cutting dies respectively, with
Reduce the deformability of the product punched out.
In order to reduce the pressure within sponge elastomer when cutting, stamping knife here uses peak cutter or one side cutter, this punching
The angular range of the knife edge of cutter is between 30 ° to 65 °；The thickness of stamping knife is between 0.5mm to 1.8mm；The height of stamping knife
Degree is between 22mm to 30mm.
After cutting in order to avoid upper slitter stamping rise time take up processed sponge elastomer, on this lower surface of cutting die and
Elastic insert it is provided with between the knife edge.
(3) hole, die-cut location: punch out several on sponge elastomer for the second location allowing alignment pin correspondence insert
Hole；
(4) punching and shaping: by sponge elastomer along feed direction transmission, sponge elastomer is respectively through the multiple moulds in set of molds
Tool, by the upper cutting die in multiple moulds and lower mold by behind the first hole, location, the second hole, location and alignment pin location matched moulds successively
Go out a plurality of line, die-cut after, the combination of a plurality of line forms the shape of product that sponge elastomer needs to be rushed out.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
