Abstract

The utility model discloses an accurate deburring die structure of aluminium foil material, including the material pressing plate of elastic connection upper die base bottom, can dismantle the drift that is fixed in upper die base bottom and symmetrical position pressure flitch both sides, be used for bearing thin material tablet and with the lower bolster of pressing the corresponding setting of material pressing plate, the both sides limit of lower bolster relative pressure flitch outwards offset certain distance respectively, this apart from the crossing punching press effect of part and drift inboard. The utility model discloses a sideline uncontrollable risk in the reduction mould production.

Description

Accurate trimming die structure for aluminum foil material
Technical Field
The utility model belongs to the technical field of the mould punching press, especially, relate to an accurate deburring mould structure of aluminium foil material.
Background
Aluminium foil material is used to inside finished piece of car, a blanking clearance must be put with the lower bolster to traditional steel sheet tablet deburring mould last mould drift when drawing the preparation, this clearance can calculate then put the blanking clearance according to the thickness of blanking tablet, it is bad to lead to its sideline easily to the finished piece product that has special material, or the burr appears, or the face that collapses, can't reach the product design requirement, and the product rejection rate is very high, thereby increase the processing cost, and the production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem, and provide the accurate deburring mould structure of aluminium foil material to sideline uncontrollable's risk in the realization greatly reduced mould production. In order to achieve the above purpose, the utility model discloses technical scheme as follows:
the precise trimming die structure for the aluminum foil material comprises a pressure plate, punches, a lower die plate, a distance and a punching effect, wherein the pressure plate is elastically connected with the bottom of an upper die base, the punches are detachably fixed at the bottom of the upper die base and are symmetrically positioned at two sides of the pressure plate, the lower die plate is used for bearing thin material pieces and is arranged corresponding to the pressure plate, two side edges of the lower die plate are respectively outwards offset by a certain distance relative to two side edges of the pressure plate, and the distance part is intersected with the inner.
Specifically, an upper base plate is arranged between the punch and the upper die base.
Specifically, the intersecting punching distance of the lower template relative to the punch is 0.1-0.15 mm.
Specifically, the bottom of the lower template is provided with a lower backing plate, and the lower template and the lower backing plate are fixed on the lower die base through screws and pins.
Specifically, the thin material sheet is an aluminum foil, and two ends of the thin material sheet extend out of the surface of the lower template.
Specifically, when the mold is opened, the natural height of the pressure plate is higher than the height of the punch.
Specifically, the inner side of the punch is of a right-angle structure.
Compared with the prior art, the utility model discloses the beneficial effect of the accurate deburring mould structure of aluminium foil material mainly embodies:
the aluminum foil trimming is different from the common trimming in that the stamping clearance is a negative value, the lower template is biased outwards by 0.15mm on the basis of the punch, an intersection value of 0.15mm is formed between the punch and the lower template, and the intersection value can be used for trimming the lower template by comparing the punch with a bench worker after the die is assembled; because the aluminum foil material is softer and has too small thickness, the stamping and trimming can be difficult to control due to deviation in the manufacturing process, and therefore the side edge line of the stamped thin material piece is accurate, and has no burr or a collapse surface.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic view illustrating the intersection of the punch and the lower die plate in the mold closing state in the present embodiment;
the figures in the drawings represent:
the die comprises an upper die holder 1, an upper backing plate 11, a material pressing plate 2, a spring 21, a punch 3, a thin material sheet 4, a lower die plate 5, a lower backing plate 51 and a lower die holder 52.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.
Example (b):
referring to fig. 1-2, the present embodiment is a precise trimming die structure for aluminum foil materials, and includes a material pressing plate 2 elastically connected to the bottom of an upper die holder 1, punches 3 detachably fixed to the bottom of the upper die holder 1 and symmetrically located at two sides of the material pressing plate 2, a lower die plate 5 for bearing a thin material sheet 4 and disposed corresponding to the material pressing plate 2, and two side edges of the lower die plate 5 are respectively outwardly offset by a certain distance from two side edges of the material pressing plate 2, and the distance part intersects with the inner side of the punches 3 for punching.
An upper backing plate 11 is arranged between the punch 3 and the upper die base 1. The pressure plate 2 is connected to the upper die holder 1 through a plurality of springs 21.
The intersecting punching distance of the lower template 5 relative to the punch 3 is 0.1-0.15 mm.
The bottom of the lower template 5 is provided with a lower backing plate 51, and the lower template 5 and the lower backing plate 51 are fixed on a lower die base 52 through screws and pins.
In this embodiment, the thin material sheet 4 is an aluminum foil, and both ends of the thin material sheet 4 extend out of the surface of the lower template 5.
When the mold is opened, the natural height of the pressure plate 2 is higher than that of the punch 3.
The inner side of the punch 3 is of a right-angle structure, the inner side of the punch 3 is punched and acted on the end part of the thin material piece 4, and due to the fact that the punch 3 and the lower template 5 have a difference value of intersecting distance, the side edge line of the punched thin material piece 4 is accurate and free of burrs.
When the embodiment is applied, the aluminum foil trimming is different from the common trimming in that the stamping clearance is a negative value, the lower template 5 is biased outwards by 0.15mm by taking the punch 3 as the standard, and an intersection value of 0.15mm is formed between the punch 3 and the lower template 5, and the intersection value can be used for trimming the lower template 5 by comparing the punch with a bench worker after the die is assembled; because the aluminum foil material is softer and has too small thickness, the stamping and trimming can be difficult to control due to deviation in the manufacturing process, and therefore the side edge line of the stamped thin material piece is accurate, and has no burr or a collapse surface.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
