Abstract

The invention provides a hardware die stamping method, which ensures the attractive and flat surface of a product when an upper plate and the product are demolded and ensures the quality of the product. The lower convex punching needle area below the upper plate is filled with foam, through holes are formed in the area, corresponding to the punching needles, of the foam, the thickness of the foam is equal to the lower convex height of the punching needles in an unpressed state, the upper plate drives the foam and the punching needles to punch products located at the lower position, the foam is elastic and is compressed in the pressing process of the upper plate, the punching needles penetrate through the corresponding through holes and protrude downwards relative to the lower surface of the foam to complete punching of the products, and the lower surface of the foam in the punching process and the unfinished demolding process is tightly pressed against the upper surface of the products, so that the products cannot move.

Description

Hardware die stamping method

Technical Field

The invention relates to the technical field of product stamping, in particular to a hardware die stamping method.

Background

When present five metals mould punching press product, it is including the upper plate, the lower surface of upper plate is provided with a plurality of protruding towards needles down, at five metals mould punching press in-process, the upper plate moves to punch towards the surface of product and forms the punching press hole that corresponds, until the lower surface laminating of upper plate presses the upper surface of attaching the product, accomplish the punching press, later the upper plate moves towards the needle and breaks away from the product, when the upper plate lifted up, can take the altitude, and then make towards the needle can cause the crease mark on the product, and then make the flaw appear.

Disclosure of Invention

Aiming at the problems, the invention provides a hardware die stamping method which ensures the attractive and flat surface of a product when an upper plate and the product are demolded and ensures the quality of the product.

A hardware die stamping method is characterized by comprising the following steps: the lower convex punching needle area below the upper plate is filled with foam, through holes are formed in the area, corresponding to the punching needles, of the foam, the thickness of the foam is equal to the lower convex height of the punching needles in an unpressed state, the upper plate drives the foam and the punching needles to punch products located at the lower position, the foam is elastic and is compressed in the pressing process of the upper plate, the punching needles penetrate through the corresponding through holes and protrude downwards relative to the lower surface of the foam to complete punching of the products, and the lower surface of the foam in the punching process and the unfinished demolding process is tightly pressed against the upper surface of the products, so that the products cannot move.

It is further characterized in that:

after the punching needle is completely separated from the product, the lower surface of the foam is separated from the upper surface of the product under the driving of the upper plate, so that the demolding is accurate and reliable;

the upper surface of the foam is fixedly arranged on the lower surface of the upper plate through bonding or an external fixed connection part, and the descending distance of the upper plate during stamping is ensured within the range of the set deformation amount in the height direction of the foam.

After the punching needle device is adopted, the lower convex punching needle area below the upper plate is filled with foam cotton, the area of the foam cotton corresponding to the punching needle is provided with a through hole, the foam cotton has elasticity, the foam cotton is compressed when the upper plate is pressed downwards, the punching needle punches through a product, when the upper plate and the punching needle are lifted, the foam cotton is restored to a prototype and always keeps a pressing state on the upper surface of the product, the foam cotton and the upper plate can be separated from the product after the punching needle is completely separated from the product, the product is always pressed and attached by the foam cotton in the punching and demolding processes, the position of the product is stable and reliable, the punching needle cannot damage the surface of the product, the appearance and flatness of the surface of the product are ensured when the upper plate and the product are demolded.

Drawings

FIG. 1 is a schematic flow diagram of a stamping method of the present invention;

the names corresponding to the sequence numbers in the figure are as follows:

the device comprises an upper plate 1, a punching needle 2, foam 3, a through hole 4 and a product 5.

Detailed Description

A hardware die stamping method is shown in figure 1: the area of a lower convex punching needle 2 below an upper plate 1 is filled with foam 3, a through hole 4 is formed in the area, corresponding to the punching needle 2, of the foam 3, the thickness of the foam 3 is equal to the lower convex height of the punching needle 2 in an unpressed state, the upper plate 1 drives the foam 3 and the punching needle 2 to punch a product 5 located below the foam 3, the foam 3 has elasticity and is compressed in the pressing process of the upper plate 1, the punching needle 2 penetrates through the corresponding through hole 4 and protrudes downwards relative to the lower surface of the foam 3 to complete punching of the product 5, and the lower surface of the foam 3 in the punching process and the demolding unfinished process is tightly pressed on the upper surface of the product 5, so that the product cannot move.

After the punching needle 2 is completely separated from the product, the lower surface of the foam 3 is separated from the upper surface of the product 5 under the driving of the upper plate 1, so that the demolding is accurate and reliable;

the upper surface of the foam 3 is fixedly arranged on the lower surface of the upper plate 1 through bonding or external connection of a fixed connecting piece, and the descending distance of the upper plate 1 during stamping is ensured within the range of the set deformation amount in the height direction of the foam 3.

The working principle is as follows: it fills the bubble cotton with protruding punching needle region under the upper plate, the bubble cotton is provided with the through hole corresponding to the region of punching the needle, the bubble cotton has elasticity, compress when the upper plate pushes down, let the punching needle punch the product, when the upper plate rises with punching the needle, the cotton answer prototype of bubble, remain the holding down state to the product upper surface all the time, treat that the punching needle leaves the product after completely, the bubble cotton just can leave the product with the upper plate together, the product is pressed by the bubble cotton all the time in punching press and drawing of patterns process and is attached, the product position is firm reliable, the punching needle can not damage the surface of product, it guarantees that the product surface is pleasing to the eye level and smooth when upper plate and product drawing of patterns, ensure the quality of product.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
