Abstract

The utility model provides a stamping die suitable for pad pasting panel, including the last mould and the lower mould of mutually supporting, the lower mould includes the die holder and sets up the die on the die holder, go up the mould and include the upper die base and set up the drift in the upper die base below, be provided with the boss on the die, treat that the punching press product is arranged in on the die, treat that the punching press product includes the panel body and paste and locate the protection film on panel body surface. The beneficial effects of the utility model are embodied in: the film is pressed by the concave die with the boss structure, so that the film reaches the strength of supporting trimming, and finally the requirement of product appearance grade is met under the condition of ensuring the standard height of burrs.

Description

Stamping die suitable for pad pasting panel

Technical Field

The utility model belongs to the technical field of stamping forming, concretely relates to stamping die suitable for pad pasting panel.

Background

The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. The work done in shear in the product processing method is die cutting. At present, the stamping occasions are more and more extensive, and for some metal plates with films pasted on the surfaces, such as plates of SUS301, aluminum plates, copper plates and the like, in the stamping process, the requirement that the burr height reaches the required standard requirement is met, and the appearance of the films pasted on the surfaces cannot be damaged. However, the existing stamping die is often adopted, and the burr height of the stamping die is not up to the standard, so that the product is finally scrapped.

SUMMERY OF THE UTILITY MODEL

The utility model provides a stamping die suitable for pad pasting panel especially is suitable for and still needs to satisfy the panel product of outward appearance grade demand after protecting and punching press through the pad pasting.

The purpose of the utility model is realized through the following technical scheme:

stamping die suitable for pad pasting panel, including the last mould and the lower mould of mutually supporting, the lower mould includes the die holder and sets up the die on the die holder, go up the mould and include the upper die base and set up the drift in the upper die base below, be provided with the boss on the die, treat that the punching press product is arranged in on the die, treat that the punching press product includes the panel body and pastes and locate the protection film on panel body surface.

Preferably, the height of the boss corresponds to the thickness of the protective film.

Preferably, the boss is arranged at the knife edge end of the female die.

Preferably, it is characterized in that: and the side of the protective film of the product to be punched is arranged on the female die.

The beneficial effects of the utility model are embodied in: the film is pressed by the concave die with the boss structure, so that the film reaches the strength of supporting trimming, and finally the requirement of product appearance grade is met under the condition of ensuring the standard height of burrs.

Detailed Description

The technical solution of the present invention is specifically described below with reference to the following examples.

Example 1

The utility model discloses a stamping die suitable for pad pasting panel, it is shown with reference to figure 2, pad pasting panel is for treating the punching press product, locate including panel body 3 and subsides the protection film 31 on 3 surfaces of panel body. The utility model discloses in panel be sheet metal, can be stainless steel, aluminum plate or copper etc.. The protective film 31 is a plastic film attached to the surface of the metal plate, and is used for protecting the produced aluminum material from being damaged in a series of processes such as carrying, storing, transporting, processing and installing.

Its stamping die includes mould and lower mould of mutually supporting, the lower mould includes the die holder and sets up die 1 on the die holder, go up the mould and include the upper die base and set up drift 2 in the upper die base below, drift 2 wear out stripper 4 with die 1 cooperatees, be provided with boss 11 on the die 1, the height of boss 11 with the thickness of protection film 31 matches. The boss 11 is arranged at the knife edge end of the female die 1. And the side of the protective film of the product to be punched is arranged on the female die 1. The utility model discloses the principle of utilization does, during the punching press, at the in-process that the drift pushed down, and boss 11 extrudees the protection film 31 of tool bit end by force for film extrusion attenuation, the mechanical strength of film increase, with reinforcing side cut intensity, final side cut back burr height B is in 8% T, T is film thickness, and can keep the requirement of product appearance. The utility model discloses an other structures of mould are similar with general stamping die, and do not belong to the scope that this application protected, so no longer give unnecessary details here.

Comparative examples

Fig. 1 shows a non-modified die, that is, an existing stamping die, and under the condition that other structures of the stamping die are not changed, the difference from embodiment 1 is that the contact surface of the female die 1 and a product to be stamped is a smooth and flat structure without a boss, the product to be stamped is placed on the surface of the female die 1, the punch 2 stamps the product, and the final burr height a is T +8% T, where T is the thickness of a film. The effect is far less than the improved mould solution.

The utility model has a plurality of specific implementation modes. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.

Claims

1. Stamping die suitable for pad pasting panel, including the last mould and the lower mould of mutually supporting, its characterized in that: the lower die comprises a lower die base and a female die arranged on the lower die base, the upper die comprises an upper die base and a punch arranged below the upper die base, a boss is arranged on the female die, a punching product is arranged on the female die, and the punching product comprises a plate body and a protective film attached to the surface of the plate body.

2. The stamping die suitable for the film-coated plate as recited in claim 1, wherein: the height of the boss is equivalent to the thickness of the protective film.

3. The stamping die suitable for the film-coated plate as recited in claim 2, wherein: the boss is arranged at the knife edge end of the female die.
