Description

A kind of automatic stamping equipment of thin-walled annular workpiece
Technical field
This utility model relates to Stamping Die Technology field, and 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 the little ring of sectional area even Together, and there is a centre bore centre, and wherein, its wall thickness of ring that sectional area is little only has 0.8 millimeter, belongs to thin-wall product, During this Product processing, difficulty is relatively big, currently in order to be suitable for batch production, mostly uses diel processing.
In diel, stepping punching mould is continuous with production, production efficiency high and receives much concern, stepping punching mould Refer to that forcing press, in one stroke, sequentially completes the stamping die of multi-step forming processes on the several different position of mould simultaneously Tool.Traditional mould structure is eight pieces of plate structures or nine pieces of plate structures, and eight blocks of plates are i.e. upper and lower die holder, punch retainer, punch Backing plate, die block, die backing plate, stripper, discharging backing plate;Nine pieces of plate structures are i.e. to add a stock guide.One The techniques such as the stamping-out of part, flange, bending, drawing, solid forming can be completed in secondary stepping punching mould.
But the different annular workpieces of two kinds of sectional areas uses stepping punching mould but to have the biggest difficulty, one is thin-walled work Part is made up of thin-walled steel strip stamping, and thin-walled steel band positions difficulty in moving process, if after especially stamping out dry hole, itself Deformation is big, and the intensity of steel band is little, and displacement location is difficult, therefore causes multiple station position inaccurate, and finished product rate is low;Two It is that the different annular workpieces of sectional area is difficult to the demoulding, complex manufacturing on stepping punching mould;After three are punch forming, need Will detect its size, particularly axially height, can produce the underproof phenomenon of axial height, radially in punching course Thickness deflection in punching course 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 diel take out, It is installed to again detect in mould detect, not only wastes time and energy, and inefficiency, can only inspect by random samples, it is impossible to accomplish every Part finished product all checks, therefore, product quality can not be protected completely.
Therefore, based on drawbacks described above, in pressing equipment field, for New Thin-walled annular work piece automatic stamping equipment still There is research and the demand improved, this is also a study hotspot in current pressing equipment field and emphasis, this practicality especially The novel starting point being accomplished and power place.
