Abstract
The invention discloses a manufacturing method for a blank of a length-unequal arc sheet metal part. The manufacturing method comprises the steps that the length-unequal arc sheet metal part is subjected to sheet metal spreading treatment by analytical software to obtain an approximate eccentric unequal side arc sheet whose arc sides R are equal; and a coil material is adopted as a raw material and manufacturing is performed on a blanking mould by adopting a mandarin duck type two-step dislocation blanking method. With the adoption of the manufacturing method of the blank of the length-unequal arc sheet metal part, an unequal side arc blank capable of being used for manufacturing the length-unequal arc sheet metal part can be manufactured on the basis of the existing blanking mould processing equipment; the processing allowance is small; the difficulty in subsequent processing can be reduced; the production efficiency can be improved; the material can be saved; the cost can be lowered; and the improvement on competitiveness of an enterprise is facilitated.
Description
Technical field
The present invention relates to a kind of sheet metal component blank manufacture method, relate in particular to a kind of not isometric arc sheet metal parts blank manufacture method that improves stock utilization.
Background technology
Not isometric arc sheet metal parts is common in the coachbuilt body sheet metal component; such as the upper inside panel in car side wall top; software is done usually to draw one after Sheet metal development is processed and is approximately the equal but eccentric inequilateral arc tablet of arc limit R by analysis; in the prior art; for saving material; its blank is made arc and non-rectangle usually; but because continuous blanking mould die point has and only has one; add and to process equilateral arc blank man-hour when carry out continuous blanking take coiled strip as raw material; so extensively adopt equilateral arc blank; its defective is that larger allowance is left at least one end of part after the processing; the following process difficulty is large; efficient is low; and stock utilization is low; production cost is high, is unfavorable for improving enterprise competitiveness.
Therefore, for addressing the above problem, need to be take existing process equipment as the basis, to being improved for the manufacture of the manufacture method of the blank of isometric arc sheet metal parts not, reduce allowance, enhance productivity and stock utilization, reduce cost.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of not isometric arc sheet metal parts blank manufacture method, adopt mandarin duck type two-step staggered blanking method, can produce inequilateral arc blank at existing blanking die process equipment, for the manufacture of not isometric arc sheet metal parts, allowance is little, can reduce the following process difficulty, enhances productivity, economical with materials, reduction cost.
Not isometric arc sheet metal parts blank manufacture method of the present invention, this not isometric arc sheet metal parts by analysis software is done to draw after Sheet metal development is processed one and is approximately that arc limit R equates but eccentric inequilateral arc tablet, it is characterized in that: take coiled strip as raw material, adopt mandarin duck type two-step staggered blanking method to make at blanking die, specifically may further comprise the steps:
A. adjust the locating piece of described blanking die, make the coiled strip center line over against the charging of blanking die cutting edge center line, excision coiled strip new line part rim charge and when the every charging of coiled strip is the double-sheet length that mandarin duck type docking forms by described inequilateral arc tablet blanking once cut out continuously the mandarin duck blank that double-sheet is combined as a whole;
B. adjust the locating piece of described blanking die, blanking once cuts out each other two inequilateral arc blanks of mandarin duck type when making described mandarin duck blank center line deviate from blanking die cutting edge center line to be described inequilateral arc tablet two arc limit eccentric throws and charging 1/2.
Further, described inequilateral arc blank end being carried out stamping-out processing makes each inequilateral arc blank structure consistent;
Further, described blanking die cutting edge R value can be set to the numerical value that a plurality of products share.
The invention has the beneficial effects as follows: not isometric arc sheet metal parts blank manufacture method of the present invention, adopt mandarin duck type two-step staggered blanking method, can produce inequilateral arc blank at existing blanking die process equipment, for the manufacture of not isometric arc sheet metal parts, allowance is little, can reduce the following process difficulty, enhance productivity, economical with materials, reduction cost, be beneficial to the raising enterprise competitiveness.

A. adjust the locating piece of described blanking die, make the coiled strip center line over against the charging of blanking die cutting edge center line, excision coiled strip new line part rim charge and when the every charging of coiled strip is the double-sheet length that mandarin duck type docking forms by described inequilateral arc tablet blanking once cut out continuously the mandarin duck blank that double-sheet is combined as a whole;
B. adjust the locating piece of described blanking die, blanking once cuts out each other two inequilateral arc blanks of mandarin duck type when making described mandarin duck blank center line deviate from blanking die cutting edge center line to be described inequilateral arc tablet two arc limit eccentric throws and charging 1/2,
Shown in Fig. 4,5, described blanking die cutting edge center line is l
1, described mandarin duck blank center line is l
2F is feedstock direction, described inequilateral arc tablet two arc limit eccentric throws are la, the double-sheet length that described inequilateral arc tablet is mandarin duck type docking formation is lb, two inequilateral arc blank eccentric throws of the each other mandarin duck type that processes equate, position by its arc limit during use, therefore can use on an equal basis.
In the present embodiment, described inequilateral arc blank end is carried out stamping-out processing make each inequilateral arc blank structure consistent, be beneficial to subsequent production processing.
In the present embodiment, described blanking die cutting edge R value can be set to the numerical value that a plurality of products share, and can improve the mould utilization rate, saves production cost.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
