Abstract

The utility model provides a be suitable for stamping die for veneer material, 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, a punched product is arranged on the female die, the upper die comprises an upper die base and a punch arranged below the upper die base, a negative gap is formed between the punch and the female die, and the punching angle of the punched product is more than or equal to 90 degrees. The beneficial effects of the utility model are embodied in: by adjusting the clearance between the punch and the female die and the punching depth of the punch, the special angle requirement of the punched end face can be ensured under the condition of meeting the requirement of smooth cutting end face.

Description

Be suitable for stamping die for glued material

Technical Field

The utility model belongs to the technical field of stamping forming, concretely relates to stamping die suitable for veneer material.

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, stamping occasions are more and more extensive, and for some glued metal materials, such as plates glued by aluminum materials and steel materials, obvious bulges and pits are often formed on the cut end face after stamping, so that product scrappage is caused, and the qualification rate is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be suitable for stamping die of veneer material, be particularly useful for the veneer material of aluminium material and steel material, and the thickness of veneer material is less.

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

be suitable for stamping die for glued material, 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, treats that the punching press product is arranged in on the die, go up the mould and include the upper die base and set up the drift in the upper die base below, the drift with be the negative clearance between the die, treat that the die-cut angle of punching press product is more than or equal to 90.

Preferably, the punch is depressed to a depth less than the thickness of the product to be punched.

Preferably, the clearance between the punch head and the female die is-0.1 mm to-0.2 mm.

Preferably, the pressing depth of the punch is smaller than 1.1 mm-1.3 mm of the thickness of a product to be punched.

Preferably, the thickness of the product to be punched is 5.0-8.8mm, and the product is formed by gluing copper and aluminum alloy.

Preferably, the punching angle of the product to be punched is 90-92 degrees.

The beneficial effects of the utility model are embodied in: by adjusting the clearance between the punch and the female die and the punching depth of the punch, the special angle requirement of the punched end face can be ensured under the condition of meeting the requirement of smooth cutting end face.

Detailed Description

Following combination embodiment specifically explains the technical scheme of the utility model, the utility model discloses a be suitable for stamping die for veneer material, figure 1 shows the utility model discloses a veneer material structure, it comprises aluminum alloy flitch 1 and the steel sheet of veneer in aluminum alloy flitch 1 below. And the thickness of the adhesive material plate is 5.0 mm-8.8 mm.

The utility model discloses a stamping die structure is similar with prior art's stamping die, all including the last mould and the lower mould of mutually supporting, upward the mould has set gradually upper padding plate, fixed plate and stripper etc. under the mould. And the stamping mechanism is arranged between the upper die and the lower die. Different from the prior art, the lower die comprises a lower die base and a female die 3 arranged on the lower die base, a product to be punched is arranged on the female die 3, and the punching mechanism comprises a punch 5 matched with the female die 3.

And a negative clearance is formed between the punch and the female die, and the clearance is-0.1 mm to-0.2 mm. The pressing depth B of the punch 5 is smaller than the thickness of a product to be punched, the general depth B is smaller than 1.1 mm-1.3 mm of the thickness of the product to be punched, and the optimal thickness difference is 1.2 mm. The adjustment of structure above makes the utility model discloses in treat under punching press product face 11 guarantees smooth no pit, its die-cut angle C realizes 90 ~ 92. And the special requirements of customers on products are met.

The different clearances affect the section angles, and the results can be specifically implemented with reference to table 1.

Table 1: relationship between different clearances and product section angles

Serial number	Gap	Angle of product cross section
			1	-0.2mm	91°
2	-0.1mm	90°~91°
			3	0mm	89°~90.5°
4	+0.1mm	87°~88°

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.
