Abstract
The utility model discloses a kind of punching cutter, including substrate, described substrate is rectangle steel plate, and substrate is provided with small one and large one two rectangular through holes, the substrate being positioned at the two through hole left and right sides is mutually symmetrical with, and the surrounding of substrate and the surrounding of each through hole are all fixed with a circle piercing tip；The top of described piercing tip is blade, and bottom is a plane, and the height of piercing tip is more than the thickness of substrate, and the blade of all piercing tips is in the same plane, and the plane of the bottom of all piercing tips and the lower surface of substrate are respectively positioned on same plane.This utility model length in service life, the punching cutter that precision is high, it is possible to ensure the precision of the protecting film size cut.
Description
Technical field
This utility model relates to a kind of cutting die, particularly relates to a kind of punching cutter for cutting thin film or leather.
Background technology
Along with the development of society, people are more and more higher to the requirement of product quality, and product is assembling, transports, using
During inevitably encounter scratch, scratch, the phenomenon such as dirty, thus affect the presentation quality of product,
Therefore the surface to product is protected necessary, at the product surface patch protecting film such as thin film or leather then
It it is a kind of common measure.In actual production, product patch protecting film before must first protecting film be cut into
Product protection position form and dimension is consistent, and the substrate of currently used cutting die is that plank makes mostly, essence
Accuracy does not reaches the highest, and use for a long time is easily caused between blade and plank and fluffs, and precision is further
Ground reduces.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of service life length, the punching cutter that precision is high,
Ensure that the precision of cut protecting film size.
In order to reach above-mentioned technique effect, the technical solution adopted in the utility model is:
A kind of punching cutter, including substrate, described substrate is rectangle steel plate, and substrate is provided with small one and large one
Two rectangular through holes, the substrate being positioned at the two through hole left and right sides is mutually symmetrical with, the surrounding of substrate and each logical
The surrounding in hole is all fixed with a circle piercing tip；The top of described piercing tip is blade, and bottom is one
Plane, the height of piercing tip is more than the thickness of substrate, and the blade of all piercing tips is in the same plane,
The plane of the bottom of all piercing tips and the lower surface of substrate are respectively positioned on same plane.
Further, the described blade often enclosing piercing tip is provided with rounding in the junction of its adjacent two sides.
Further, described piercing tip thickness from the top to the bottom is gradually increased.
Further, described substrate is additionally provided with some perforation, and two described perforation are symmetrically distributed in little through hole
The left and right sides.
Further, at a circle piercing tip outer ledge bottom it of described substrate surrounding and corner
Junction is equipped with rounding.
Compared with prior art, the beneficial effects of the utility model are: described substrate is rectangle steel plate, substrate
It is provided with through hole, substrate and through hole surrounding and is fixed with piercing tip so that this utility model length in service life,
The punching cutter that precision is high, it is possible to ensure the precision of the protecting film size cut.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand of the present utility model
Technological means, and can being practiced according to the content of description, and in order to allow of the present utility model above-mentioned and
Other objects, features and advantages can become apparent, and below especially exemplified by preferred embodiment, and coordinates accompanying drawing,
Described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile in the A-A direction of Fig. 1.
Each label and corresponding entitled in figure:
1. substrate, 2. through hole, 3. piercing tip, 4. perforation.
Detailed description of the invention
A kind of punching cutter, including substrate 1, described substrate 1 is rectangle steel plate, and substrate 1 is provided with one big one
Two little rectangular through holes 2, the substrate 1 being positioned at two through hole 2 left and right sides is mutually symmetrical with, the four of substrate 1
The surrounding of all and each through holes 2 is all fixed with a circle piercing tip 3.The top of piercing tip 3 is blade,
Bottom is a plane, and often the blade of circle piercing tip 3 is provided with rounding in the junction of its adjacent two sides.
The height of piercing tip 3 is more than the thickness of substrate 1, and piercing tip 3 thickness from the top to the bottom is gradually increased.
The blade of all piercing tips 3 is in the same plane, the plane of the bottom of all piercing tips 3 and substrate 1
Lower surface be respectively positioned on same plane.Described substrate 1 is additionally provided with two perforation 4, two symmetrical point of perforation 4
Cloth is in the left and right sides of little through hole 2.For safety, a circle piercing tip 2 of substrate 1 surrounding is at its end
At the outer ledge in portion and the junction of corner is equipped with rounding.Adopt between piercing tip 2 and substrate 1
The mode fixed with bolt or weld is fixing to be connected.
Utility model works principle: operationally, is fixed on this utility model on the upper table surface of press machine,
On the following table of press machine, correspondence position fixes backing plate, and backing plate area is more than area of the present utility model, institute
The protecting films such as the thin film that need to cut or leather are placed on backing plate that (certainly, punching cutter is permissible with the position of backing plate
Exchange), press machine works, and is molded by punching cutter and presses protecting film, thus is die-cut to by protecting film
Required shape.
This utility model is rectangle steel plate due to substrate 1, and substrate 1 is provided with through hole 2, substrate 1 and through hole 2 surrounding
It is fixed with piercing tip 3 so that this utility model length in service life, precision are high, it is possible to guarantee is cut
The precision of protecting film size.Rounding is used so that this practicality is new in the adjacent side junction often enclosing blade
The die-cut product of type is attractive in appearance, reduces product breakage rate simultaneously, provides cost savings.Piercing tip 3 is from top
Being gradually increased to bottom thickness, substrate 1 is provided with perforation 4 so that die-cut rear product and waste material are easy to fall off, unlikely
In blocking this utility model；Certainly, it is possible to apply in the back side of the present utility model perforation 4 or through hole 2 position
Blowning installation, makes product and waste material more easy to fall off.
This utility model is not limited to above-mentioned specific embodiment, for the person of ordinary skill of the art from
Above-mentioned design is set out, and without performing creative labour, done all conversion, all falls within this utility model
Protection domain within.
