Abstract
The present invention relates to a kind of bending of aluminium foil products with fastening moulding process.Aluminium foil products are in forming machine, it is necessary to which the edge to aluminium foil products carries out bending with fastening shaping after punching molding.Advantage be float upper clearance requirement between mould and bending insert and the upper mould peripheral profile that floats to be necessary for sharp angle requirement be outward appearance in order to improve product and the shape of product that avoids aluminium foil product front in compacting from having more spilling；Polishing requirement under floating on the outside of mould peripheral profile is in order to which product smoothly deviates from the lower mould of floating and prevention product in ejection process deformation；Gap under floating between mould and bending insert（It is consistent with product wall thickness）, the big stability for being unfavorable for product bending in gap；Mould and the clearance requirement fastened between insert are outward appearance in order to improve product and avoid aluminium foil product front in compacting from having more the shape of product of spilling in floating；It is in order to which bending edges are smoothly fastened as desired shape along the type face for fastening insert to fasten the requirement of insert type mirror polish.
Description
Technical field
The present invention relates to aluminium foil products manufacture field, and in particular to a kind of bending of aluminium foil products is with fastening moulding process.
Background technology
It by raw material is that the flat aluminium sheet formed ears is compressing by mould that aluminium foil class product majority, which is, in order to improve the strong of product
Degree and product design it is attractive in appearance, need to by product outer ring carry out bound edge.But how the good edge of effective rapid processing, study always
Problem.
The content of the invention
In order to solve the above problems, it is skilful with fastening moulding process, design that the present invention proposes a kind of bending of aluminium foil products
Wonderful, perfect technology improves efficiency, meets customer requirement.
Technical scheme：
The bending of aluminium foil products is with fastening moulding process, and aluminium foil products are in forming machine, it is necessary to aluminium foil products after punching molding
Edge carry out bending with fasten be molded,
1）Aluminium foil products are handled down through die clamp under float upper mould and floating, and the bending insert on upper mould is descending aluminium foil products
Edge carry out bending, upper modular belt moves bending insert backhaul, and the lower mould that floats makes mould and edge bending position under floating to contract
Leave fastening distance；
2）Fastening insert on lower mould inwardly extrudes the bending position of aluminium foil products edge, and the bending position of edge is inlayed along fastening
Type face designed by block fastens shaping.
Gap in described floating between mould and bending insert is designed as being less than or equal to 0.1mm.
Mould peripheral profile is sharp angle in described floating.
Under described floating minute surface is finished on the outside of mould peripheral profile.
Described the 1st）Float the edge thickness that lower gap between mould and bending insert is aluminium foil products in step.
Type face designed by described fastening insert is to be provided with a step in the Angle Position of extruding, and step lower end is designed to spoon
Sub- shape, step upper side is plane, and the type mirror polish is minute surface.
Mould and the gap fastened between insert are less than or equal to 1mm under described floating.
Gap between the plane of the step upper side of described fastening insert and the upper mould that floats is less than or equal to 0.1mm.
It is an advantage of the invention that：
1. float upper clearance requirement between mould and bending insert and the upper mould peripheral profile that floats be necessary for sharp angle requirement be for
Improve the outward appearance of product and avoid aluminium foil product front in compacting from having more the shape of product of spilling；
2. the polishing requirement on the outside of the lower mould peripheral profile that floats is that mould and prevention product exist under smoothly deviating to float for product
Ejection process is deformed；
3. lower gap between mould and bending insert of floating（It is consistent with product wall thickness）, gap is big to be unfavorable for the steady of product bending
It is qualitative；
4. float upper mould and the clearance requirement that fastens between insert is outward appearance in order to improve product and avoids aluminium foil in compacting
Middle product front has more the shape of product of spilling；
5. it is in order to which bending edges are smoothly fastened as desired shape along the type face for fastening insert to fasten the requirement of insert type mirror polish.
Brief description of the drawings
Fig. 1 is the schematic diagram of the bending of the present invention.
Fig. 2 is close-up schematic view at A in Fig. 1.
Fig. 3 is the schematic diagram of the fastening of the present invention.
Fig. 4 is close-up schematic view at B in Fig. 3.
Embodiment
Referring to the drawings 1-4, the bending of aluminium foil products is with fastening moulding process, aluminium foil products punching molding in forming machine
Afterwards, it is necessary to which the edge to aluminium foil products carries out bending with fastening shaping,
1) such as Fig. 1-2, aluminium foil products are clamped down through float upper mould 1 and the lower mould 2 that floats, under the bending insert 3 on upper mould
The edge of aluminium foil products is carried out bending by row, and upper mould 4 drives the backhaul of bending insert 3, and the lower mould 2 that floats makes under floating to contract
Mould 2 leaves fastening distance with edge bending position；Gap in described floating between mould 1 and bending insert 3 is designed as being less than
Equal to 0.1mm.The peripheral profile of mould 1 is sharp angle 7 in described floating.Being finished on the outside of the peripheral profile of mould 2 under described floating
Minute surface.Described the 1st）Float the edge thickness that lower gap between mould 2 and bending insert 3 is aluminium foil products in step.
2）Fastening insert 5 on such as Fig. 3-4, lower mould inwardly extrudes the bending position of aluminium foil products edge, the bending of edge
Position fastens along the type face designed by insert 5 that fastens and is molded.Type face designed by described fastening insert 5 is the Angle Position in extruding
A step is provided with, step lower end is designed to spoon shape 6, and step upper side is plane, and the type mirror polish is minute surface.Institute
Mould 2 and the gap fastened between insert 5 are less than or equal to 1mm under the floating stated.The step upper side of described fastening insert 5
Gap between plane and the upper mould 1 that floats is less than or equal to 0.1mm.
Clearance requirement and the upper peripheral profile of mould 1 that floats in floating between mould 1 and bending insert 3 are necessary for sharp angle requirement
It is outward appearance in order to improve product and avoids aluminium foil product front in compacting from having more the shape of product of spilling；Float lower mould 2
Polishing requirement on the outside of peripheral profile is that mould 2 and prevention product are deformed in ejection process under smoothly deviating to float for product；
