Abstract
The invention belongs to machining technology, and relates to a method for strengthening the rigidity of linearly cut rectangular sheet materials. The method is characterized by comprising steps: machining a strengthening plate; and adhering the strengthening plate. By the aid of the method, the rigidity of a rectangular sheet material is strengthened, workload of a linear cutting machine tool is not increased during linear cutting, waste of materials is avoided, and cost is reduced.
Description
Technical field
The invention belongs to Machining Technology, relate to a kind of line cutting rectangular thin plate rigidity of material intensifying method.
Background technology
Wire cutting machine tool often runs into the problem that thin plate is difficult for clamping when the processing sheet material.Because the thinner thickness of light sheet material, the sagging phenomenon of workpiece can take place man-hour adding in the rigidity deficiency, influences the machining accuracy of part.Present solution is: carry out clamping with bigger two boards of thickness together after with the whole clamping of light sheet material, and then the line cutting processing, add the man-hour board and cut together.The shortcoming of this method is: need to increase by two boards identical with the light sheet material area, board is also destroyed during cutting, not only increased the workload of wire cutting machine tool, caused the waste of workload, and owing to board is destroyed, can't reuse, cause the waste of material, increase cost.
Summary of the invention
The objective of the invention is: propose a kind of line cutting rectangular thin plate rigidity of material intensifying method that does not increase the workload of wire cutting machine tool, the material that avoids waste.
Technical scheme of the present invention is: line cutting rectangular thin plate rigidity of material intensifying method, and it is characterized in that: the step that rigidity is strengthened is:
1, processing stiffener: two long limit stiffeners 2 and two broadside stiffeners 3 that stiffener is made by metallic plate are formed, width b=30mm～the 60mm of long limit stiffener 2 and broadside stiffener 3, thickness t=10mm～the 30mm of long limit stiffener 2 and broadside stiffener 3, the length L 1 of long limit stiffener 2 equals the length of rectangular thin plate material, the length L 2=L3-2a-2b of broadside stiffener 3, L3 is the width of rectangular thin plate material, and a is that the termination of broadside stiffener 3 is to the distance of long limit stiffener 2;
2, bonding stiffener: earlier two long limit stiffeners 2 are bonded on the long limit of rectangular thin plate material, the outward flange of long limit stiffener 2 and the long limit justified margin of rectangular thin plate material, the two ends of long limit stiffener 2 and the broadside justified margin of rectangular thin plate material, then two broadside stiffeners 3 are bonded on the broadside of rectangular thin plate material, the broadside justified margin of the outward flange of broadside stiffener 3 and rectangular thin plate material, the termination of broadside stiffener 3 is a to the distance of long limit stiffener 2; Used glue is J 39 metal bonded adhesives; Bonding back air dry is more than 12 hours.
Advantage of the present invention is: strengthened the rigidity of rectangular thin plate material, do not increased the workload of wire cutting machine tool during online cutting, avoided the waste of material, reduced cost.

The specific embodiment
Below the present invention is described in further details.Referring to Fig. 1, line cutting rectangular thin plate rigidity of material intensifying method, it is characterized in that: the step that rigidity is strengthened is:
1, processing stiffener: two long limit stiffeners 2 and two broadside stiffeners 3 that stiffener is made by metallic plate are formed, width b=30mm～the 60mm of long limit stiffener 2 and broadside stiffener 3, thickness t=10mm～the 30mm of long limit stiffener 2 and broadside stiffener 3, the length L 1 of long limit stiffener 2 equals the length of rectangular thin plate material, the length L 2=L3-2a-2b of broadside stiffener 3, L3 is the width of rectangular thin plate material, and a is that the termination of broadside stiffener 3 is to the distance of long limit stiffener 2;
2, bonding stiffener: earlier two long limit stiffeners 2 are bonded on the long limit of rectangular thin plate material, the outward flange of long limit stiffener 2 and the long limit justified margin of rectangular thin plate material, the two ends of long limit stiffener 2 and the broadside justified margin of rectangular thin plate material, then two broadside stiffeners 3 are bonded on the broadside of rectangular thin plate material, the broadside justified margin of the outward flange of broadside stiffener 3 and rectangular thin plate material, the termination of broadside stiffener 3 is a to the distance of long limit stiffener 2; Used glue is J39 metal bonded adhesives; Bonding back air dry is more than 12 hours.
Operation principle of the present invention is: two long limits and two broadsides of online cutting rectangular thin plate material are distinguished bonding two long limit stiffeners and two broadside stiffeners, the intensity of long limit stiffener and broadside stiffener is big, rigidity is stronger, with become as a whole after light sheet material is bonding, light sheet material has been played the effect that stretches and fix, made the rigidity of light sheet material obtain reinforcement.Defectives such as light sheet material is sagging, distortion can not take place in process, strengthened the rigidity of line cutting rectangular thin plate material, the machining accuracy of light sheet material is improved.
Embodiment 1, online cutting processing thickness is 0.8mm, length is 320mm, width be certain aircraft product of 300mm use exterior template rectangular thin plate material the time, having made two width is 30mm, thickness is 10mm, material is the long limit stiffener of structural carbon steel, the length of this length limit stiffener equals the length 320mm of light sheet material, and to have made two width be 30mm, thickness is 10mm, material is the broadside stiffener of structural carbon steel, the termination of this broadside stiffener is 10mm to the distance of long limit stiffener, and the length of this broadside stiffener is 300-20-60=220mm.Then two long limit stiffeners are bonded on the long limit of rectangular thin plate material, the outward flange of long limit stiffener and the long limit justified margin of rectangular thin plate material, the two ends of long limit stiffener and the broadside justified margin of rectangular thin plate material, then two broadside stiffeners are bonded on the broadside of rectangular thin plate material, the broadside justified margin of the outward flange of broadside stiffener and rectangular thin plate material, the termination of broadside stiffener is 10mm to the distance of long limit stiffener; Used glue is J39 metal bonded adhesives; Bonding back air dry just can be gone up wire cutting machine tool and processed more than 12 hours.
