Embodiment Construction

[0016] Such as image 3 As shown, a bending and cutting method with a notch, the specific steps are as follows:

[0017] ① CNC cutting square hole 3 on the plate from the root of the gap;

[0018] ② Stamping and bending according to the design requirements to the assembly requirements;

[0019] ③ Manually cut the excess plate along the sides 4 of the square hole 3 into gaps that meet the assembly requirements.

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 [0001] The invention relates to a processing method for plates, in particular to a bending cutting method for plates with notches. Background technique [0002] Such as figure 1 The shown special container is fixed together by a curved plate 1 with a notch and an inserting plate 2, and there must be no gap between the plate 1 and the inserting plate 2. Therefore, there are strict requirements on the bending radian of the plate 1, and the production method of the curved plate with notches is as follows: [0003] Option 1. First cut the gap of the board according to the assembly size requirements (see figure 2 ), and then press and bend the sheet. Disadvantages are: due to the gaps cut by CNC on the board, the arc cannot be well controlled during bending. After assembly, the gap between the board and the insert board is relatively large, which cannot guarantee the stability of the structure, and at the same time causes a large amount of repair work.
