Abstract
The invention provides a foam punching method with a small distance between two holes, which ensures that the edges of the holes with the small distance are not hulled and ensures the quality of products. The cotton hole of bubble that the cotton thickness direction of bubble was provided with two sets of equipartitions is first bubble cotton hole, the cotton hole of second bubble respectively, the minimum marginal interval in the cotton hole of first bubble, the cotton hole of second bubble is not more than 1mm, and it is through the whole first bubble cotton hole of punching press of first cutting die, later first cutting die wholly shifts up, through the whole punching press of second cutting die out second bubble cotton hole, later the whole shift up of second cutting die.
Description
Technical Field
The invention relates to the technical field of foam stamping, in particular to a foam stamping method with a small distance between two holes.
Background
When the existing foam is punched, the method of punching and forming the product hole at one time is adopted, but because the distance between the holes is small, the two holes are punched simultaneously to deform the foam, so that the edge of the foam hole can peel off the release film, and the quality of the product cannot be guaranteed.
Disclosure of Invention
In view of the above problems, the present invention provides a method for stamping foam with a small distance between two holes, which ensures that the edges of the holes with a small distance are not peeled off, and ensures the quality of the product.
A foam stamping method with a small distance between two holes is characterized in that: the cotton hole of bubble that the cotton thickness direction of bubble was provided with two sets of equipartitions is first bubble cotton hole, the cotton hole of second bubble respectively, the minimum marginal interval in the cotton hole of first bubble, the cotton hole of second bubble is not more than 1mm, and it is through the whole first bubble cotton hole of punching press of first cutting die, later first cutting die wholly shifts up, through the whole punching press of second cutting die out second bubble cotton hole, later the whole shift up of second cutting die.
It is further characterized in that:
a positioning hole is preset in the foam, a corresponding positioning bulge of the lower die is positioned behind the positioning hole, a corresponding first cutting die and a corresponding second cutting die are respectively and fixedly arranged on the upper die through two vertical driving components, and the first cutting die and the second cutting die are respectively and independently driven;
the lower end face of the upper template is pressed on the upper end face of the foam, and corresponding through avoidance holes are respectively formed in the upper template corresponding to the knife edge of the first cutting die and the knife edge of the second cutting die;
a plurality of first cutting dies are respectively arranged on the first cutting die driving plate, a plurality of second cutting dies are respectively arranged on the second cutting die driving plate, the first cutting die driving plate is located above the second cutting die driving plate, corresponding through yielding holes are formed in the second cutting die driving plate corresponding to the cutting edges of the first cutting dies, and the vertical moving distance of the first cutting die driving plate and the vertical moving distance of the second cutting die driving plate are not interfered.
After the method is adopted, the first foam hole is integrally punched by the first cutting die, then the first cutting die is integrally moved upwards, the second foam hole is integrally punched by the second cutting die, and then the second cutting die is integrally moved upwards, namely the first foam hole and the second foam hole are independently punched by the two times of cutting die punching respectively, so that the edges of the holes with smaller intervals cannot be hulled, and the quality of the product is ensured.
Detailed Description
A foam stamping method with a small distance between two holes comprises the following steps: the cotton hole of bubble that the cotton thickness direction of bubble was provided with two sets of equipartitions is first bubble cotton hole, the cotton hole of second bubble respectively, and the minimum marginal interval in the cotton hole of first bubble, the cotton hole of second bubble is not more than 1mm, and it is through the whole first bubble cotton hole of punching press of first cutting die, later first cutting die wholly shifts up, through the whole punching press of second cutting die out the cotton hole of second bubble, later the whole shift up of second cutting die.
A positioning hole is preset in the foam, a corresponding positioning bulge of the lower die is positioned behind the positioning hole, a corresponding first cutting die and a corresponding second cutting die are respectively and fixedly arranged on the upper die through two vertical driving components, and the first cutting die and the second cutting die are respectively and independently driven to be arranged;
the lower end face of the upper template is pressed on the upper end face of the foam, and corresponding through avoidance holes are respectively formed in the upper template corresponding to the knife edge of the first cutting die and the knife edge of the second cutting die;
a plurality of first cutting dies are arranged on the first cutting die driving plate respectively, a plurality of second cutting dies are arranged on the second cutting die driving plate respectively, the first cutting die driving plate is arranged above the second cutting die driving plate, corresponding through yielding holes are formed in the second cutting die driving plate corresponding to the cutting edges of the first cutting dies, and the vertical moving distance of the first cutting die driving plate and the vertical moving distance of the second cutting die driving plate are not interfered.
In a specific embodiment, the minimum edge distance between the first foam hole and the second foam hole is 0.7mm, and the processed foam holes are not peeled.
After the method is adopted, the first foam hole is integrally punched by the first cutting die, then the first cutting die is integrally moved upwards, the second foam hole is integrally punched by the second cutting die, and then the second cutting die is integrally moved upwards, namely the first foam hole and the second foam hole are independently punched by the two times of cutting die punching respectively, so that the edges of the holes with smaller intervals cannot be hulled, and the quality of the product is ensured.
The detailed description of the embodiments of the present invention is provided above, but the present invention is only the preferred embodiments of the present invention, and should not be considered as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the invention as claimed should be covered by this patent.
