Abstract
A method for bending and cutting a plate with a notch relates to a method for machining a plate and solves the technical problem that an existing manufacturing method cannot meet the requirement on bending radian while ensuring cutting quality, and cannot ensure cutting quality while meeting the requirement on bending radian. The method includes the specific steps: firstly, cutting a square hole at the root of the notch on the plate by means of numerical control; secondly, stamping and bending the plate to meet assembly requirements according to design requirements; and thirdly, manually cutting a redundant portion of the plate into the notch meeting assembly requirements along two sides of the square hole. The method is used for bending and cutting the plate with the notch, not only can meet the requirement of the plate with the notch on radian after bending, but also can ensure cutting quality, and reduces the labor intensity of workers.
Description
Technical field
The present invention relates to the processing method of sheet material, particularly be used to have the crooked cutting method of breach sheet material.
Background technology
Special container as shown in Figure 1 is fixed together by bent plate that has breach 1 and plate 2, must not be gapped between sheet material 1 and the plate 2.Therefore, strict to the crooked radian of sheet material 1, now the preparation method to the bent plate that has breach is following:
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art.A kind of bending and cutting method that has breach sheet material is provided, solves existing preparation method and when guaranteeing cut quality, can't satisfy crooked radian, when satisfying crooked radian, can't guarantee the technical problem of cut quality.
The present invention realizes through following technical scheme:
A kind of bending and cutting method that has breach sheet material, concrete steps are following:
1. on sheet material from root of notch elder generation Numerical control cutting square hole;
2. carry out bending ram to matching requirements according to designing requirement;
3. along the dual-side of square hole unnecessary sheet material hand cut is become to meet the breach of matching requirements.
The present invention compared with prior art owing to occur not carrying out bending ram before the breach at sheet material, can guarantee to bend precision more accurately, after the bending again with the remaining coupling part of indentation, there hand cut.Because the indentation, there major part is accomplished by Numerical control cutting, the hand cut amount is less, and labor strength is less.The present invention is used to have the bending cutting of breach sheet material, and the radian requirement behind the both satisfied band breach sheet bending can guarantee cut quality again, reduces labor strength.
Description of drawings
Fig. 1 is a kind of structural representation (front view) of special container;
Fig. 2 is that the sheet material that has breach launches sketch map;
Fig. 3 adopts the present invention to make sheet material to launch sketch map.
The present invention is elaborated through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 3, a kind of bending and cutting method that has breach sheet material, concrete steps are following:
1. on sheet material from root of notch elder generation Numerical control cutting square hole 3;
2. carry out bending ram to matching requirements according to designing requirement;
3. along the dual-side 4 of square hole 3 unnecessary sheet material hand cut is become to meet the breach of matching requirements.
Claims (1)
1. a bending and cutting method that has breach sheet material, concrete steps are following:
1. on sheet material from root of notch elder generation Numerical control cutting square hole (3);
2. carry out bending ram to matching requirements according to designing requirement;
3. along the dual-side (4) of square hole (3) unnecessary sheet material hand cut is become to meet the breach of matching requirements.
