Abstract
The invention discloses a cold stamping assistive device and a stamping process thereof. The assistive device is a gasket located between a stamping piece and a convex mold; the contact surface of the gasket and the stamping piece is matched with the stamping piece in shape; and the contact surface between the gasket and the convex mold is a plane. With the adoption of the assistive device and a machining method, the product quality is improved; after being shaped, a product which is stamped by using the process can meet the requirements of components, so as to meet the requirements of clients; and moreover the working procedures are reduced; and the cost is reduced.
Description
Technical field
The present invention relates to the cold stamping field, in particular, relate to a kind of accessory and Sheet Metal Forming Technology thereof the former material bending ram of camber line.
Background technology
In the technology that cold stamping is shaped; The strip piece that is camber line for the cross section dashes when curved, and the phenomenon of cracking, fold, folded material appears in the shape face regular meeting of stamping parts, and these phenomenons can have influence on outward appearance, the quality of finished product; Even finished product is scrapped; The measure of taking at present is when punching press, the shape face to be carried out reinforcement, Jia Bao, adds and draw groove, even increases the preform treatment process one, but still can not reach ideal effect.
Summary of the invention
Technical problem to be solved by this invention is to realize that a kind of strip piece of guaranteeing that the cross section is camber line dashes curved no cracking, fold, folds the punching press accessory and the process thereof of expecting phenomenon.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of cold stamping accessory, this accessory are the pad between stamping parts and punch, and the contact-making surface of described pad and stamping parts and stamping parts shape adapt, with the contact-making surface of punch be the plane.
Described pad is processed by having elasticity and quality soft polyurethane, rubber or plastic cement.
Stamping parts length before described pad and the punching press, thickness error are ± 10%.
A kind of Sheet Metal Forming Technology of utilizing accessory comprises:
During described step 2 shaping and punching, the matched moulds time needs more than 3 seconds.
The invention has the advantages that this accessory and processing method thereof have improved product quality,, pass through after the shaping again through the product of taking this technology to suppress out; Meet the requirement of part fully, thereby satisfy requirement of client, and reduced operation; Reduced cost, specifically, the shape face of some part; Needing increases several roads preform mould, just can reach the shape face requirement of part; Also to amplify the scantling of product, to satisfy the requirement of flanging, like this, even press forming also must increase trimming die.Thereby increased cost (costs such as raw material, processing, manual work) greatly; And the appearance of this new technology has just changed everything well.After at first shimming was shaped basically, it was just passable only to need on same pair of mould, to carry out shaping; The required tablet of product need not put the flanging surplus afterwards, directly the disposable position that is put into of the spread material of part, as long as can satisfy the dimensional requirement of part.
Description of drawings
Facing the content of every width of cloth accompanying drawing expression in the specification of the present invention and the mark among the figure down briefly explains:
Fig. 1 is a cold stamping accessory user mode explosive view;
Fig. 2,3 is a stamping parts finished product sketch map;
Mark among the above-mentioned figure is: 1, punch; 2, die; 3, pad; 4, stamping parts.
The specific embodiment
Can know that referring to Fig. 1-3 the cold stamping accessory is the pad 3 between stamping parts 4 and punch 1, stamping parts 4 is metal blanks that are circular arc, wavy or special-shaped shape such as circular-arc through punching press cross section; Need under punch 1 of the present invention and die 2 punching presses, accomplish crooked stamping procedure during the secondary punching press with the crooked punching press different directions first time; Yet camber line shape face knee can produce unnecessary material, before punch 1 and die 2 are not incorporated into the end, and the material that these are unnecessary; Will be deposited in the gap of mould; Treat that mould is incorporated at the end, these unnecessary material will be superimposed, and form folded material or fold.And after adding pad 3 between stamping parts 4 and the punch 1, can eliminate mould and be incorporated into the space between the stamping parts 4 and mould before the end, force stamping parts 4 all the time with open and flat, full state conformal.Therefore this pad 3 need adapt with stamping parts 4 with the contact-making surface shape of stamping parts 4; For example be semi-cylindrical, wavy or camber line shape, the contact-making surface of another side and punch 1 is the plane, and two end faces also are the plane; And stamping parts 4 thickness (whole height) before the thickness of pad 3, length and the punching press, error in length are ± 10%; Preferred pad 3 is slightly less than the size of stamping parts 4, is advisable to fill up stamping parts 4 cavitys, and matched moulds process Intermediate gasket 3 can be filled whole die cavity like this; Therefore make the soft rubber-like nonmetallic materials of material require of pad 3, can select to have elasticity and soft polyurethane, rubber or the plastic cement of quality.
Utilize above-mentioned pad 3 to add man-hour, mainly be divided into following four steps:
Need to prove: my this new Sheet Metal Forming Technology only is suitable for the book plate (book is good more more) below the 1.0mm; Material can be gold, silver, copper, aluminium, iron, 409L (to hard metal material, effect is bad).
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
