Grooving device and method for arc-shaped plate

Abstract

The invention aims at providing a grooving device and method for an arc-shaped plate. The grooving device comprises a long-strip-shaped grooving limiting plate with the bottom face being an arc face, a plurality of adjusting strips and a fastening mechanism used for fixing the grooving limiting plate to a sound absorber arc-shaped plate. The radian of the bottom face of the grooving limiting plate is consistent with that of the sound absorber arc-shaped plate, a limiting through groove is formed in the slotting limiting plate, the length of the limiting through groove is larger than or equal to that of the longest through groove in the sound absorber arc-shaped plate, and the width of the limiting through groove is equal to or larger than that of the through groove in the sound absorber arc-shaped plate. The width of the adjusting strip is equal to or smaller than that of the limiting through groove; during grooving, the grooving limiting plate is fixed to the preset grooving position of the arc-shaped plate, the corresponding adjusting strip is selected to be placed in the limiting through groove of the grooving limiting plate according to the length of the through groove, so that the length of the adjusting strip is equal to the length difference between the limiting through groove and the through groove, and finally grooving operation is conducted on the arc-shaped plate along the limiting through groove through a grooving tool.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a plate slotting device and method. Background technique [0002] Such as figure 1 As shown, in some acoustic structures (such as sound-absorbing wall panels in theaters and other occasions), it is necessary to open a number of slots extending along the axial direction of the arc-shaped plate (usually fiberboard) on the arc-shaped plate. Due to the needs of acoustic functions, Although these slots have the same width, their positions and lengths are different. The traditional way is to fix the arc-shaped board on the workbench, draw the outline of the slot with a pen at the predetermined position of the arc-shaped board in advance, and then the worker Using a slotting tool to open a through slot with a predetermined length and position on the curved plate, the above slotting operation is not only complicated and inefficient, but also there is no tooling...

Problems solved by technology

[0002] such as As shown in Figure 1, in some acoustic structures (such as sound-absorbing wall panels in theaters and other occasions), it is necessary to open a number of slots extending along the axial direction of the arc-shaped plate (usually fiberboard), Due to the needs of the acoustic function, although these slots have the same width, their positions and lengths are different. The traditional method is to draw the slots at the predetermined position of the arc board with a pen after fixing the arc board on the workbench. Then the worker uses the slotting tool to open a through slot with a predetermined length and position on the curved plate. The above slotting operation is not only complicated and inefficient, but also there is no tooling to limit the slotting tool during slotting. , it is difficult to ensure that the slotting route completely conforms to the contour of the slot, so it is difficult to guarantee the slotting quality
