Abstract

The invention relates to a bending method, in particular to a method for quickly and precisely positioning bending of a steel plate. By the method, the problems that positioning time is relatively long and an error is easy to cause in the current bending process are solved. The method comprises the following steps of drawing two bending sharp angles on the outer sides of the two ends of a part on a part bending drawing, wherein the connecting line at the outer ends of the two bending sharp angles forms a bending central line, and the bending sharp angles are directly cut off when a part is blanked; and when the part is bent, directly aligning the bending central line formed by the connecting line at the outer ends of the two bending sharp angles with an upper die cutter on one straight line. The method of drawing the bending sharp angles comprises the following steps of respectively drawing a circle by taking the cross points of the two end points of the bending central line and the edge of the part as circle centers, wherein the diameter of the circles is three times the thickness of a plate; and connecting two cross points of the circles and the edge of the part, and the cross point of the circles and the bending central line to form a triangle, thus the bending sharp angles are formed. The structure is simple, production is convenient to perform, the production period is shortened, and the bending molding efficiency and the bending molding quality are improved.

Description

Steel plate is accurately located the method for bending fast
Technical field
The present invention relates to a kind of bending method, particularly a kind of steel plate is accurately located the method for bending fast.
Background technology
The bending and molding technology of steel plate has the characteristics that moulding is fast, efficient is high, can keep steel plate original structure performance, is widely used in industrial every field.At present, divided for three steps in the bending and molding manufacture process: at first rule and find out the bending center line, then steel plate is placed on the cutter groove, the center line of aiming at the bending cutter with the bending center line of part carries out centering, descends the cutter bending at last.In the whole bending process, line and two steps of centering are comparatively lost time, and will influence the bending size owing to reasons such as sight line, angle often have some errors during centering.Therefore, need a kind of quick pinpoint method to solve this problem.
Summary of the invention
The present invention has solved the problem that present bending process grows and be easy to generate error positioning time through a kind of quick pinpoint bending method is provided.
The present invention realizes through following technical scheme:
A kind of steel plate is accurately located the method for bending fast; At first directly 2 bending wedge angles are drawn in the outside, the two ends of part on the part bending drawing, and the line of 2 bending wedge angle outer ends forms the bending center line, directly cuts out the bending wedge angle during part blanking; During part bending; The bending center line that directly lets 2 bending wedge angle outer end lines form aligns with the patrix cutter and can directly carry out bending point-blank, and bending cuts the bending wedge angle and gets final product after accomplishing.
The method that the bending wedge angle is drawn is: with the two-end-point of bending center line and the intersection point of part edge is the center of circle; Each draws a circle; Diameter is 3 times of thickness of slab, connects circle and two intersection points of part edge and the intersection point triangularity of circle and bending center line, promptly forms the bending wedge angle.
When cutting the bending wedge angle, adopt the plasma cutting.
Adopt Numerical control cutting to cut out the bending wedge angle during part blanking.
The present invention is simple in structure, and is convenient for production, shortens the production cycle, improves bending and molding efficient and quality.
Description of drawings
Fig. 1 is the method sketch map that the present invention draws the bending wedge angle;
Fig. 2 is the part sketch map that has the bending wedge angle among the present invention.
The specific embodiment
As shown in Figure 2, among the present invention, need bending component to combine by part itself and bending wedge angle; When drawing the bending component drawing, draw 2 bending wedge angles at the two ends of bending center line, the method for drawing the bending wedge angle is: with the two-end-point of bending center line and the intersection point of part edge is the center of circle; Each draws a circle, and diameter is 3 times of thickness of slab, connects 3 intersection point triangularities on the circle then; And for the bending wedge angle, as shown in Figure 1; Part directly cuts out the bending wedge angle with the precision of the bending center line of numerical control cutting machine blanking assurance bending wedge angle formation during blanking; During part bending, need not reproduce field measurement bending center line, directly let bending wedge angle in two ends align, can directly carry out bending point-blank with the patrix cutter; After bending is accomplished, adopt the plasma cutting, cut the bending wedge angle and get final product.
