Description
Technical field
The present invention relates to a kind of mould, more particularly to a kind of arc-shaped workpiece processing mold and its processing method, belong to mould Design and processing technique field.
Background technology
All it is by lower cavity die and band with arc groove generally when the thin arc-shaped products such as arc clamshell or workpiece is processed The upper male mould of arc bump is completed, so that straight sheet metal is placed between punch and matrix, then coordinate forcing press by its Compacting camber, so as to as the clamshell of various equipment.Existing punch and matrix is respectively one integral piece, i.e., with block or column gold Category blank, processes one integral piece cavity plate, punch-pin, it is clear that this one integral piece cavity plate, convex respectively by machining equipments such as lathe, milling machines Mould, especially big part one integral piece cavity plate, punch-pin, not only processing difficulties, the expense that wastes time and energy material, and process one integral piece cavity plate, Punch-pin can be difficult to be sent to Working position, weight weight big because of volume, it is necessary to could be completed using special lifting appliance, while making When being processed with one integral piece cavity plate, punch-pin, arc-shaped product is easily set to produce arc to offset because of resilience after completion of processing, it is difficult to Accurately accurate measurement is obtained, the influence later stage installs or assembles.Therefore, it is necessary to be improved prior art.
The content of the invention
Easily processed it is an object of the invention to provide one kind, and arcuate structure is entirely capable of meeting arc-shaped product or workpiece Process technology requirement, is easily installed the arc-shaped workpiece die for processing on forcing press.
The present invention also provides the preparation method of above-mentioned arc-shaped workpiece die for processing.
First purpose of the invention is completed by following technical proposal：A kind of arc-shaped workpiece processing mold, including punch-pin And cavity plate, it is characterised in that some punch-pin pieces that punch-pin is convex by lower end, upper end is die shank are stacked and form, and cavity plate is by upper end For arcs of recesses, lower end form for some cavity plate pieces at mould bottom are stacked.
The convex of the punch-pin piece is divided into：The base segmental arc at middle part, positioned at the resilience segmental arc of base segmental arc both sides, position Straight section on the outside of resilience segmental arc；Wherein：The arc radius of base segmental arc are more than the arc radius of resilience segmental arc, to add The accurate measurement required for keeping is remained to after work arc-shaped workpiece resilience out.
Arc radius 0.5-6mm of the arc radius of the base segmental arc more than resilience segmental arc.
The punch-pin piece is provided with multiple through holes, after some punch-pin pieces are stacked, by the bolt and nut that are placed in through hole Some punch-pin pieces are fastened for a punch-pin entirety.
The segment length of the straight section is 10-20mm, and length is too small to influence formed precision, and length crosses conference and causes mould material Material is wasted, and increases mold weight.
The resilience segmental arc forms springback angle with straight section the tangent, and the angle of the springback angle is 0-5 °.
The arcs of recesses of the cavity plate piece is divided into：The base segmental arc at middle part, positioned at the resilience segmental arc of base segmental arc both sides, position Straight section on the outside of resilience segmental arc；Wherein：The arc radius of base segmental arc are more than the arc radius of resilience segmental arc, so as to The accurate measurement required for keeping is remained to after the arc-shaped workpiece resilience for processing.
Arc radius 0.5-6mm of the arc radius of the base segmental arc more than resilience segmental arc.
Multiple through holes are set on the cavity plate piece, it is tight by the bolt and nut that are placed in through hole after some cavity plate pieces are stacked Gu some cavity plate pieces are a cavity plate entirety.
The segment length of the straight section is 10-20mm, and length is too small to influence formed precision, and length crosses conference and causes mould material Material is wasted, and increases mold weight.
The resilience segmental arc forms springback angle with straight section the tangent, and the angle of the springback angle is 0-5 °.
Second object of the present invention is completed by following technical proposal：A kind of preparation side of arc-shaped workpiece processing mold Method, it is characterised in that comprise the following steps：
A, the base segmental arc that punch-pin convex and cavity plate arcs of recesses are set to middle part, positioned at the resilience arc of base segmental arc both sides Shape section, the straight section on the outside of resilience segmental arc, and resilience segmental arc and straight section the tangent are defined as springback angle, the springback angle Angle be 0-5 °, the length of straight section is set to 10-20mm；
B, the base segmental arc half that punch-pin convex, cavity plate arcs of recesses are determined according to the arc radius R workpiece of arc-shaped workpiece to be processed Footpath R mould bases, specifically by following determination：
As R workpiece ＞ 80mm：R moulds base=R workpiece/1.25；
As R workpiece≤80mm：R moulds base=R workpiece；
The radius of base segmental arc is R mould bases, then the arc radius R moulds bullet=R moulds -0.5-6mm of resilience segmental arc；
C, punch-pin die shank size is determined according to compressor size, and cavity plate mould bottom size；
D, according to punch-pin, cavity plate size, number of openings and size are set；
E, the size determined according to step A-D, corresponding some punch-pin pieces and cavity plate piece are cut out with sheet metal；
When F, processing arc-shaped workpiece, some punch-pin pieces are stacked on the corresponding die shank of bender, while some cavity plate pieces are folded Put in the corresponding groove of bender, wherein：The stacked thickness of punch-pin, cavity plate is adapted with the width of arc-shaped workpiece to be processed；Will Some punch-pin, cavity plate are adjacent to after aligning integrally respectively, corresponding logical through stacked integral punch-pin, cavity plate with bolt respectively Kong Zhong, and with nut fasten after, metal sheet to be processed is put between punch-pin, cavity plate, routinely operate bender, that is, obtain Required arc-shaped workpiece.
The cutting of the step E is cut with conventional cleaver, preferably laser cutting machine cutting.
The present invention has following advantages and effect：Using such scheme, it is convenient to if punch-pin, cavity plate are arranged respectively to Dry punch-pin piece, cavity plate piece, not only easy to process, time saving material-saving, and some punch-pin pieces, the cavity plate piece that will easily can be processed Be installed to one by one in the corresponding die shank of bender, groove, and align it is stacked after tightly may be used with bolt and nut, you can will treat Processing metal sheet is put between punch-pin, cavity plate and is bent into required arc-shaped workpiece, without using Large-scale Hoisting machine can easily by Punch-pin, cavity plate are attached on bender, and can increase and decrease punch-pin piece, cavity plate piece quantity according to workpiece to be processed width, while will be convex The convex and cavity plate piece arcs of recesses of matrix be divided into middle part base segmental arc, the resilience segmental arc of both sides, the straight section in outside, and Make the arc radius of base segmental arc more than the arc radius of resilience segmental arc, while controlling resilience segmental arc with straight section the tangent Spring back angle is 0-5 °, it is ensured that after the arc-shaped workpiece resilience for processing, and will not also change its accurately accurate measurement, after convenience It is continuous to install.
