Description
Technical field
The present invention relates to the cold stamping shaped technical field of thin plate, specifically the blank of a kind of swing type sheet metal doffer and using method thereof and this method punch die of application.
Background technology
At present, the cold stamping shaped technology in thin-sheet metal is to use a kind of plastic forming technology very widely, has high-quality, efficient, in enormous quantities, material-saving, energy-conservation and advantage cheaply.The thin-sheet metal stamping parts is used on the products such as automobile, space flight and aviation, boats and ships, machinery in a large number.The shape and size of the Forming Quality of cold stamping shaped product and processability and blank have direct relation: the too small meeting of blank causes plate to flow through bead fully, therefore loses pressure-pad-force and drawing pressure, finally causes stamping parts wrinkling; On the contrary, if blank is excessive, can cause raw-material waste.In large-scale mass production, each single-piece conservation of raw material in a small amount all can bring very considerable economy to be benefited.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide the blank of a kind of swing type sheet metal doffer and using method and this method punch die of application.
The technological means that the present invention adopts is as follows:
A kind of swing type sheet metal doffer is characterized in that: the punch die of described doffer comprises left side section punch die, stage casing punch die and right section punch die; Described left side section punch die, described stage casing punch die and described right section punch die are tooth-shaped edge;
Described left side section punch die flexibly connects with the fulcrum I of described stage casing punch die, and described left side section punch die can be to swing in the scope of β with horizontal sextant angle around described fulcrum I, and β is satisfied: 0 °≤β≤45 °;
Described right section punch die flexibly connects with the fulcrum II of described stage casing punch die, and described right section punch die can be to swing in the scope of α with horizontal sextant angle around described fulcrum II, and α is satisfied: 0 °≤α≤45 °.
But above-mentioned tooth-shaped edge phalanges saw tooth-shaped edge, semicircle cut edge, trapezoidal side cut or the other forms of side cut that is beneficial to enforcement all can, be not limited to above-mentioned several situations.Section punch die in a left side is being to swing in the scope of β around the fulcrum I with horizontal sextant angle, and β is in 0 °～15 ° scopes, and is better for effect in the actual production, same, and right section punch die is in α is 0 °～15 ° scopes, and is also better for effect in the actual production.
As preferably, described punch die can swing up and down around described doffer center.
As preferably, described swing up and down refer to described punch die with described left side section punch die not with the scope of the fixing end of described fulcrum I around described doffer center swing γ, γ satisfies :-45 °≤γ≤45 °; And/or described punch die with described right section punch die not with the scope of the fixing end of described fulcrum II around described doffer center swing δ, δ satisfies :-45 °≤δ≤45 °.
Angle γ and δ that above-mentioned punch die integral body swings up and down around the doffer center are advisable in ± 20 ° of scopes.
As preferably, the degree of depth of described tooth-shaped edge is s mm.
The invention also discloses the using method of above-mentioned swing type sheet metal doffer, it is characterized in that: carry out the punch die blanking after left side section punch die, stage casing punch die and the right section punch die of described doffer are adjusted according to default angle.
The plate form of punching press according to actual needs, the punch die of adjustment doffer carries out blanking then.
The present invention and then disclose a kind of blank of using the using method punch die of above-mentioned swing type sheet metal doffer is characterized in that: described blank comprises effective forming part and is arranged on the profile of tooth flanging portion of described effective forming part both sides.
As preferably, the width of described profile of tooth flanging portion is s mm.
Need the inflow of suitable drawing pressure control plate from blank holder to cavity body of mould in the thin-sheet metal punch forming process, namely to the control of charging.Drawing pressure realizes by the bead on the blank holder that normally the shape and size of different beads can produce different drawing pressures, and, fillet less bead dark such as the degree of depth can produce bigger drawing pressure.Bead is come into force fully, and sheet bar needs enough big, can cover the fillet on bead punch and the die in the punch forming process.
The periphery of traditional blank all is straight line or big radian curve, and by swing type sheet metal doffer of the present invention according to the cold stamping shaped charging control principle in thin-sheet metal, the ingenious nested concept of blank of utilizing is produced the blank that corresponding both sides become profile of tooth flanging portion.The effective dimensions of such blank is suitable with traditional blank, can produce sufficient drawing pressure, and equivalent dimension (being the step-length of uncoiling blanking) is little, thereby reduces the engineering waste material of stamping parts, improve raw-material utilization rate, for stamping factory is saved raw material greatly.
Doffer of the present invention adopts flexible double oscillating type design, can produce the sheet bar of multiple shape and size once secondary doffer, make the application of this device not be subjected to the restriction of the size of capacity and output size, it is simple to have version, advantages such as practical operation is convenient are widely used in the punching press field of industries such as automobile, boats and ships, aviation, household electrical appliances.
