Abstract

The present invention provides a kind of big thickness alloy plate material blanking die of small deformation, including cavity plate and punch-pin, the cavity plate center offers discharge opening, the punch-pin is concentric just to setting with cavity plate discharge opening, and the diameter of punch-pin is less than discharging bore dia, the cavity plate punching end end outer wall is taper surface so that the punching end of cavity plate forms punching cutting edge.The present invention makes the deflection of part after processing by controlling angle at cutting edge of die and cavity plate to be controlled with punch-pin gap, around punching, that is radial displacement and axial displacement of the part with cavity plate contact position, part warpage size etc., part deformation amount is small after processing;For 50mm thickness aluminum alloy parts, about 30s spent by drilling, and the time used in punching of the present invention is used for 10s, labor intensity is reduced, production efficiency is greatly improved.

Description

A kind of big thickness alloy plate material blanking die of small deformation
Technical field
The invention belongs to technical field of mold, the big thickness alloy plate material blanking die of more particularly to a kind of small deformation.
Background technology
Use drilling process the hole shaping of the aluminum alloy part (such as aluminium alloy wheel hub) of big thickness, this method can be with Ensure that part deformation amount is in controlled range after processing, but it is less efficient, such as thickness in 50mm aluminium alloy wheel hub drilling, institute Take time and had more twice compared with punching.Instrument cost (bit cost and punching that drilling expends consumed for production unit product The punch die expense of consuming), drilling has had more by about one time compared with punching.In addition drilling operation labor intensity is high, and automaticity is poor.
The method also having using being punched is shaped for such aluminium alloy hole at present, but deflection is big, part is easy after punching Cracking, it is impossible to ensure machining accuracy, yield rate is low.
The content of the invention
The deficiencies in the prior art, are closed it is an object of the invention to provide a kind of big thick aluminium of small deformation in view of the above Golden plate material blanking die, improves production efficiency, reduces labor intensity.
In order to achieve the above objects and other related objects, technical solution of the present invention is as follows:
A kind of big thickness alloy plate material blanking die of small deformation, including cavity plate and punch-pin, the cavity plate center is opened up There is discharge opening, the punch-pin is concentric just to setting with cavity plate discharge opening, and the diameter of punch-pin is less than discharging bore dia, the cavity plate Punching end end outer wall is taper surface so that the punching end of cavity plate forms punching cutting edge.
As preferred:The cavity plate is located above punch-pin, and punch-pin is cylindrical, and cavity plate external wall of upper portion is outside cylinder, bottom Wall is the conical surface that from top to bottom diameter is tapered into.
As preferred:The cavity plate external wall of upper portion is provided with a circle installation base.
As preferred:The discharge opening bottom is circular hole, and top is up big and down small taper hole.
As preferred:The taper surface is 8-12 degree relative to the angle of inclination at the vertical center of cavity plate.
As preferred:The thickness of the punching cutting edge is 1mm-2mm.
As preferred:The punch-pin lower diameter is more than upper diameter, and punch-pin lower end center offers threaded connection hole, institute State punch-pin upper lateral and offer pin-and-hole.
As described above, the beneficial effects of the invention are as follows:By controlling angle and cavity plate and punch-pin gap at cutting edge of die To control the deflection of part after processing, including around punching, i.e. radial displacement and axial position of the part with cavity plate contact position Shifting amount, part warpage size etc., part deformation amount is small after processing;For 50mm thickness aluminum alloy parts, spent by drilling about 30s, and the time used in punching of the present invention is used for 10s, labor intensity is reduced, production efficiency is greatly improved.

Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation Content disclosed by book understands other advantages and effect of the present invention easily.
As shown in figure 1, a kind of big thickness alloy plate material blanking die of small deformation, including cavity plate 1 and punch-pin 2, cavity plate 1 Center offers discharge opening 11, and punch-pin 2 and the discharge opening 11 of cavity plate 1 are concentric just to setting, and the diameter of punch-pin 2 is less than discharge opening 11 Diameter, the punching of the cavity plate 1 end end outer wall is taper surface so that the punching end of cavity plate 1 forms punching cutting edge 12.
Further scheme is that cavity plate 1 is located at the top of punch-pin 2, and punch-pin 2 is cylindrical, and the external wall of upper portion of cavity plate 1 is cylinder, Bottom outer wall is the conical surface that from top to bottom diameter is tapered into, to form the cutting edge 12 of punching.The external wall of upper portion of cavity plate 1 is provided with one Installation base 13 is enclosed, is connected for being installed with equipment.The bottom of discharge opening 11 for being opened in the center of punch-pin 2 is circular hole, and top is upper Small taper hole, to be collected after the completion of being punched to waste material, and takes out from the discharge opening 11 of cavity plate 1 under big.The punch-pin 2 Lower diameter is more than upper diameter, and the lower end center of punch-pin 2 offers threaded connection hole 21, is fixed for being installed with blanking equipment, The upper lateral of punch-pin 2 offers the pin-and-hole 22 perpendicular to the axis of punch-pin 2, when being installed with blanking equipment, in pin-and-hole 22 Bearing pin is installed, bearing pin is located in blanking equipment simultaneously, prevents punch-pin 2 from swinging.
The optimal dimensional structure of punch-pin 2 and cavity plate 1 is have found with sunykatuib analysis by constantly testing:Taper surface relative to The angle of inclination a at the vertical center of cavity plate 1 is 8-12 degree, can take 10 degree in this example.In order to ensure impression of the cutting edge 12 to workpiece In prescribed limit, and Reducing distortion amount etc., the thickness L of punching cutting edge 12 is controlled in 1mm-2mm.
Cavity plate 1 is in concentric position with punch-pin 2, and its axiality is maintained atWithin.During processing, cavity plate 1 is fixed, Part delivers to processing stations (between cavity plate 1 and punch-pin 2) by automatic conveying belt, and after after part positioning, punch-pin 2 is to the direction of cavity plate 1 It is mobile, finally cause material separation, form punching.For 50mm thickness aluminum alloy parts, about 30s spent by drilling, and punching Time used is 10s.Part after processing is made by controlling angle at the cutting edge 12 of cavity plate 1 and cavity plate 1 to be controlled with the gap of punch-pin 2 It is radial displacement and axial displacement of the part with the contact position of cavity plate 1, part warpage size around deflection, including punching. Labor intensity is reduced, production efficiency is greatly improved.And deflection is small.
Any person skilled in the art can all be carried out under the spirit and scope without prejudice to the present invention to above-described embodiment Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed spirit with All equivalent modifications completed under technological thought or change, should be covered by the claim of the present invention.
