Description
Technical field
The present invention relates to Stamping Die Technology field, the automatic press particularly relating to a kind of thin-walled annular workpiece sets
Standby.
Background technology
Having kind of a thin-walled annular product aborning, it is shaped as a big ring of sectional area and a sectional area is little
Ring connect together, and there is a centre bore centre, and wherein, its wall thickness of ring that sectional area is little only has 0.8 milli
Rice, belongs to thin-wall product, and during this Product processing, difficulty is relatively big, currently in order to be suitable for batch production, mostly
Employing diel is processed.
In diel, stepping punching mould is to produce continuous, production efficiency height and to receive much concern, grading
Diel refers to that forcing press, in one stroke, sequentially completes many on the several different position of mould simultaneously
The diel of road stamping procedure.Traditional mould structure is eight pieces of plate structures or nine pieces of plate structures, eight blocks of plates
It is i.e. upper and lower die holder, punch retainer, convex mould pad, die block, die backing plate, stripper, unloads
Backing strap plate；Nine pieces of plate structures are i.e. to add a stock guide.Can complete in a secondary stepping punching mould
The techniques such as the stamping-out of part, flange, bending, drawing, solid forming.
But the different annular workpieces of two kinds of sectional areas uses stepping punching mould but to have the biggest difficulty, one is
Thin-wall workpiece is made up of thin-walled steel strip stamping, and thin-walled steel band positions difficulty in moving process, especially stamps out
If after dry hole, the deformation of itself is big, and the intensity of steel band is little, and displacement location is difficult, therefore causes multiple
Station position is inaccurate, and finished product rate is low；Two is that the different annular workpieces of sectional area is at stepping punching mould
On be difficult to the demoulding, complex manufacturing；After three are punch forming, need its size is detected, especially
Being axial height, can produce the underproof phenomenon of axial height in punching course, radial thickness is in punching press
In journey, deflection is little, it is not necessary to detection, in the manufacturing process of the different annular work piece of sectional area, and punching press
During need mould, be also required to corresponding mould during detection, after punching press completes, by product by punching press
Mould takes out, then is installed in detection mould detect, not only waste time and energy, and inefficiency,
Can only inspect by random samples, it is impossible to accomplish that every finished product all checks, therefore, product quality can not obtain completely
To ensureing.
Therefore, based on drawbacks described above, in pressing equipment field, for the automatic punching of New Thin-walled annular work piece
