Description
Technical Field
The utility model relates to a hole dashes technical field, particularly, relates to a two-period form stainless steel hole dashes.
Background
The traditional one-section type hole punch is easy to tear in a hole and shear in the shearing process due to poor material flowability, so that a two-section type stainless steel hole punch is urgently needed.
SUMMERY OF THE UTILITY MODEL
Problem (A)
To sum up, the utility model relates to a two-stage type stainless steel hole is towards, through structure and functional improvement to solve the hole of above-mentioned traditional hole towards a segmentation and cut the problem at the in-process because of the material mobility is not good, easily produce downthehole two scissors problems of tearing.
(II) technical scheme
The utility model provides a two-period form stainless steel hole is towards, include: mould main part, installation piece, die head, two-stage punching area and one section punching area, its characterized in that: the die is characterized in that one side of the top end of the die body is fixedly connected with an installation block, the top end of the die body is fixedly connected with a die head, the outer side of the lower surface of the die head is fixedly connected with a two-section punching area, the bottom end of the die head is fixedly connected with a one-section punching area, and the top end of the one-section punching area is fixedly connected with the two-section punching area.
Preferably, the first punching area and the second punching area are identical in structure, and the central axes of the first punching area and the second punching area are overlapped.
Preferably, the width and length of the two sections of punching areas are both larger than the height and length of the one section of punching area by 0.25 mm.
Preferably, the height difference between the first-stage punching area and the second-stage punching area is 0.25 mm.
(III) advantageous effects
1. The utility model discloses a set up the two-stage section and punch a hole district and one section district of punching a hole, make the two-stage form stainless steel hole towards when punching a hole, well can play the secondary and scrape the hole, reach and supply and tear the material, can advance downthehole two of tearing and cut the problem, make its downthehole section 100% bright.
2. The utility model has the advantages of through setting up the installation piece, make two-stage form stainless steel hole towards be convenient for fixed mounting on stamping equipment.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In fig. 1, the corresponding relationship between the part names or lines and the reference numbers is:
the die comprises a die body-1, a mounting block-2, a die head-3, a two-section punching area-4 and a one-section punching area-5.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
Example (b):
referring to fig. 1, the present invention provides a two-stage stainless steel hole punch, including: mould main part 1, installation piece 2, die head 3, two-stage process punching area 4 and one section district 5 of punching a hole, 1 top one side fixed connection of mould main part is equipped with installation piece 2, 1 top fixed connection of mould main part is equipped with die head 3, 3 lower surface outsides fixed connection of die head are equipped with two sections district 4 of punching a hole, 3 bottom fixed connection of die head are equipped with one section district 5 of punching a hole, and 5 tops in one section district of punching a hole and two sections 4 fixed connection of district of punching a hole.
The first-stage punching area 5 and the second-stage punching area 4 are identical in structure, and central axes of the first-stage punching area and the second-stage punching area are overlapped, so that when the two-stage stainless steel hole punch performs punching operation, the first-stage punching area 5 and the second-stage punching area 4 are both located in the middle of punching.
Wherein, the width and the length of the two-section punching area 4 are both larger than the height and the length of the one-section punching area 5 by 0.25mm, the section difference of 0.25mm between the one-section punching area 5 and the two-section punching area 4 is ground by improving through repeated tests of a die, and the section of the scraping forming hole is changed from the original 50% bright band to 100% bright band, thereby thoroughly solving the problem of the hole section, and improving the die repairing efficiency and the production quality.
Wherein, the height difference between the first-stage punching area 5 and the second-stage punching area 4 is 0.25mm, and the improvement of the repeated test of the die enables the second-stage punching area 4 to play a role in secondary hole scraping in the shearing process, so as to supplement the tearing material, pre-solve the problem of tearing the second shearing in the hole and enable the inner section of the hole to be 100% bright.
The implementation scheme is as follows:
when the two-stage stainless steel hole punch is used for punching, the die main body 1 is installed on a punching machine and is fixedly installed through the installation block 2;
when punching operation is carried out, the first-section punching area 5 is firstly contacted with the surface of a product to carry out first-section punching on the product, and then the second-section punching area 4 carries out second-section punching on the first-section punching area of the product, so that the second-section punching area 4 can play a role of secondary hole scraping in the shearing process to supplement tearing materials, the problem of tearing of the second shearing in the hole can be solved, and the inner section of the hole is 100% bright.
