Abstract
A kind of large-scale rubber, all apart from fixed number drilling method, relates to the application of difference bisection method in large-scale rubber.Its operating procedure is as follows: A. determines the baseline that punches; B. to design punching total length L mark hole, first, last hole heart point; C. the segments n of selected punching total length L; D. each section length N is calculated; E. order mark punching segmentation; F. last Kong Kongxin and the overall error W designing last Kong Kongxin is measured; G. calculate and wait point error distribution amount G; H. a point error distribution amount G such as grade be assigned to each order punching section and again revise punching segment identification; I. carrying out difference to each segmentation again by step B ~ H divides equally once, can determine that punching is implemented in the heart position, hole of actual punching.The present invention is that the Mathematical Method of difference being divided equally applies to greatly neatly, heavy weight rubber product all apart from fixed number drilling process.Application of the present invention, drastically increase operating efficiency and product punching qualification rate, alleviate the labour intensity of operating personnel, the screw matching coordinative of product and rigid body connector is improved very well.
Description
Technical field
The present invention relates to the application of difference bisection method in large-scale rubber.
Background technology
Rubber is elastomer, its precision size can change because of the change of External Force Acting, environment temperature, particularly large, heavy weight rubber product, as closed hoop products such as gas storage holder rubber rolling curtain film, the various large-scale diaphragm of rubber of used in nuclear power station, weigh more than several tons, molding procedure, movement, stacking difficulty, because tractive, extruding size also can change, be difficult to the actual size that employment work accurately measures product.In order to the screw cooperation with attaching parts in erection unit, large, heavy weight rubber product porous must be solved and all to punch a difficult problem apart from fixed number.People use two kinds of methods usually: a kind of bisection method that adopts processes, and now product girth is divided into 2 parts, then divides 4 parts, 8 parts, 16 parts ... until till regulation hole count.Because product is excessive, overweight, be difficult to operation in actual applications, often occur that decile is inaccurate and need repeat, uncertainly reach required precision.Another kind method carrys out the row's of pushing away identification hole heart with one section of rigid body model, because product size there occurs change, and there is small error in each pitch-row, push away to be discharged to and finally will accumulate out very large error, it not how several hole, be exactly few several hole, be difficult to ensure that hole count just in time and be uniformly distributed.Above two kinds of methods, the shortcoming obviously existed is that error is large, duplication of labour intensity is large, efficiency is low, the qualification rate of product punching is low, with hanging attaching parts screw difficult coordination.
Summary of the invention
The object of the invention is to solve all to punch a difficult problem apart from fixed number in large, heavy weight rubber product Manual punching operation.
For achieving the above object, its technical scheme designs a kind of large-scale rubber all apart from fixed number drilling method, and its operating procedure is as follows:
A. the baseline that punches is determined: on product, draw the punching baseline with sides aligned parallel by design drawing requirement;
B. Theoretical Design punching total length L mark hole, first, last hole heart point is determined: the punching total length of annular closed type product is product girth, and first, last hole overlaps; The distance of Kong Kongxin to last Kong Kongxin headed by the punching total length of planar products;
C. the segments n of selected punching total length L: selecting a segments n, n according to the odd even of hole count with punching total length L is the natural number of 3 ~ 13, and n is the common divisor of L;
D. each section length N is calculated:
;
E. order mark punching segmentation N
1, N
2, N
3n
n;
F. measure actual push away discharge last Kong Kongxin and the overall error W of Theoretical Design end Kong Kongxin: exceeding Theoretical Design end Kong Kongxin is "-" value, and not reaching Theoretical Design end Kong Kongxin is "+" value;
G. calculate and wait point error distribution amount G:
;
H. a point error distribution amount G such as grade be assigned to each order punching section and again revise punching segment identification;
I. carrying out difference to each segmentation again by step B ~ H divides equally once, can determine that punching is implemented in the heart position, hole of actual punching.
The present invention is that the Mathematical Method of difference being divided equally applies to greatly neatly, heavy weight rubber product all apart from fixed number drilling process.The accumulated error caused by many reasons is effectively disperseed, and makes each pitch-row error narrow down to and can ignore.Application of the present invention drastically increases operating efficiency and product punching qualification rate, and alleviate the labour intensity of operating personnel, the screw matching coordinative of product and rigid body connector is improved very well.
Detailed description of the invention
embodiment:the upper and lower edge of used in nuclear power station diaphragm of rubber needs all apart from fixed number punching, and top edge girth 18165 ㎜, need make a call to 240 uniform holes, and lower limb girth 18793 ㎜ need make a call to 250 uniform holes.Now only for lower limb punching, describe concrete operation method of the present invention and step in detail:
A. the punching baseline with lower edges parallel is drawn apart from lower limb 80 ㎜;
B. determine theoretical punching total length L=18793 ㎜, identify first Kong Kongxin;
C. the segments n=10 of selected L;
D. the length of each segmentation is calculated
㎜;
E. sequence identification punching section: N
1, N
2, N
3n
10;
F. N is measured
10punching section end Kong Kongxin identification point is to the overall error W=+60 ㎜ of first Kong Kongxin;
G. point error distribution amount of grade is calculated
㎜;
H. be assigned to by a point error distribution amount G such as grade in each order punching section, namely every section of increase by 6 ㎜ revise each order punching section again;
Every section of 1879+6=1885 ㎜ is divided equally 5 segments again, every segment is 377 ㎜.In 377 ㎜, divide equally 5 pitch-row sections, each hole heart apart from being 75.4 ㎜, its operation is easy to operate.
