Abstract
The invention discloses a kind of Length discrepancy arc sheet metal parts blank manufacture method, this Length discrepancy arc sheet metal parts by analysis software show after doing Sheet metal development process that is approximately the equal but inequilateral arc tablet for bias of arc limit R, take coiled strip as raw material, blanking die adopts the manufacture of mandarin duck type two-step staggered blanking method, Length discrepancy arc sheet metal parts blank manufacture method of the present invention, adopt mandarin duck type two-step staggered blanking method, inequilateral arc blank can be produced on existing blanking die process equipment, for the manufacture of Length discrepancy arc sheet metal parts, allowance is little, following process difficulty can be reduced, enhance productivity, save material, reduce costs, be beneficial to raising enterprise competitiveness.
Description
Technical field
The present invention relates to a kind of sheet metal component blank manufacture method, particularly relate to a kind of Length discrepancy arc sheet metal parts blank manufacture method improving stock utilization.
Background technology
Length discrepancy arc sheet metal parts is common in coachbuilt body sheet metal component, as inside panel on car side wall top, software can show after doing Sheet metal development process that is approximately the equal but inequilateral arc tablet for bias of arc limit R usually by analysis, in the prior art, for saving material, its blank makes arc and non-rectangle usually, but have due to continuous blanking mould die point and only have one, when being that raw material carry out continuous blanking and add and can only process equilateral arc blank man-hour with coiled strip, so extensively adopt equilateral arc blank, its defect is that after processing, larger allowance is left at least one end of part, following process difficulty is large, efficiency is low, and stock utilization is low, production cost is high, be unfavorable for improving enterprise competitiveness.
Therefore, for solving the problem, needing, based on existing process equipment, to be improved the manufacture method of the blank for the manufacture of Length discrepancy arc sheet metal parts, reducing allowance, enhancing productivity and stock utilization, reduce costs.
Summary of the invention
In view of this, the object of this invention is to provide a kind of Length discrepancy arc sheet metal parts blank manufacture method, adopt mandarin duck type two-step staggered blanking method, inequilateral arc blank can be produced on existing blanking die process equipment, for the manufacture of Length discrepancy arc sheet metal parts, allowance is little, can reduce following process difficulty, enhance productivity, saves material, reduce costs.
Length discrepancy arc sheet metal parts blank manufacture method of the present invention, this Length discrepancy arc sheet metal parts by analysis software show after doing Sheet metal development process that is approximately the equal but inequilateral arc tablet for bias of arc limit R, it is characterized in that: take coiled strip as raw material, blanking die adopts the manufacture of mandarin duck type two-step staggered blanking method, specifically comprises the following steps:
A. the locating piece of described blanking die is adjusted, make coiled strip center line just to the charging of blanking die cutting edge center line, excision coiled strip new line part rim charge and the every charging of coiled strip by described inequilateral arc tablet be mandarin duck type dock the double-sheet length formed time blanking once, cut out the mandarin duck blank that double-sheet is combined as a whole continuously;
B. the locating piece of described blanking die is adjusted, make described mandarin duck blank center line deviate from blanking die cutting edge center line be described inequilateral arc tablet two arc limit eccentric throw and charging is 1/2 of double-sheet length time blanking once, cut out two inequilateral arc blanks of mandarin duck type each other.
Further, carrying out punch press process to described inequilateral arc blank end makes each inequilateral arc blank structure consistent;
Further, described blanking die cutting edge R value can be set to the numerical value that multiple product shares.
The invention has the beneficial effects as follows: Length discrepancy arc sheet metal parts blank manufacture method of the present invention, adopt mandarin duck type two-step staggered blanking method, inequilateral arc blank can be produced on existing blanking die process equipment, for the manufacture of Length discrepancy arc sheet metal parts, allowance is little, following process difficulty can be reduced, enhance productivity, save material, reduce costs, be beneficial to raising enterprise competitiveness.

Detailed description of the invention
Fig. 1 is the equilateral arc blank schematic diagram of prior art, Fig. 2 is inequilateral arc blank schematic diagram of the present invention, Fig. 3 is the material use comparison diagram of the present invention and prior art, Fig. 4 is blanking schematic diagram in step a, Fig. 5 is blanking schematic diagram in step b, as shown in the figure: Length discrepancy arc sheet metal parts blank manufacture method of the present invention, this Length discrepancy arc sheet metal parts by analysis software show after doing Sheet metal development process that is approximately the equal but inequilateral arc tablet for bias of arc limit R, take coiled strip as raw material, blanking die adopts the manufacture of mandarin duck type two-step staggered blanking method, specifically comprise the following steps:
A. the locating piece of described blanking die is adjusted, make coiled strip center line just to the charging of blanking die cutting edge center line, excision coiled strip new line part rim charge and the every charging of coiled strip by described inequilateral arc tablet be mandarin duck type dock the double-sheet length formed time blanking once, cut out the mandarin duck blank that double-sheet is combined as a whole continuously;
B. the locating piece of described blanking die is adjusted, make described mandarin duck blank center line deviate from blanking die cutting edge center line be described inequilateral arc tablet two arc limit eccentric throw and charging is 1/2 of double-sheet length time blanking once, cut out two inequilateral arc blanks of mandarin duck type each other
As shown in Figure 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 throw is la, described inequilateral arc tablet be mandarin duck type docking formed double-sheet length be lb, two inequilateral arc blank eccentric throws of the type of mandarin duck each other processed are equal, positioned by its arc limit during use, therefore can use on an equal basis.
In the present embodiment, punch press process is carried out to described inequilateral arc blank end and makes 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 multiple product shares, and can improve mould utilization factor, save production cost.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
