Sawing numerical-control equipment used for right-angled circular-arc chamfering in board

Abstract

The invention provides sawing numerical-control equipment used for right-angled circular-arc chamfering in a board. The sawing numerical-control equipment is characterized by comprising a rack, a sawing mechanism used for board positioning and sawing processing, a z-axis mechanism for driving the sawing mechanism to move back and forth along a z axis, and a board pressing mechanism for pressing and fixing the board, wherein a supporting platform for supporting the board is arranged on the rack; the sawing mechanism is connected to the z-axis mechanism; the board pressing mechanism is positioned above the supporting platform; the sawing mechanism comprises a sawing mounting board, an upper sawing assembly and a lower sawing assembly; both the upper sawing assembly and the lower sawing assembly are arranged on the sawing mounting board; and the sawing mounting board is connected to the z-axis mechanism. The sawing numerical-control equipment can realize right-angled circular-arc chamfering in the board, saves labor post, improves board processing efficiency and board processing precision, can improve processing consistency, is simple in structure, is high in reliability, and can prevent the surface of the board from being damaged.

Description

technical field [0001] The invention relates to the technical field of plate processing, and more specifically relates to a sawing numerical control device for right-angled arc chamfering in plates. Background technique [0002] At present, custom-made furniture is more and more popular because of its tailor-made features, and the tailor-made features require that the custom-made furniture be installed in a perfect fit with the existing columns and beams in the room, so as to achieve the existing columns and beams. The beams are covered and hidden. Typically, panels with an internal right-angle shape are used for fitting to columns and beams. In addition, this kind of plate with inner right angle shape is also used in the internal assembly of custom furniture. [0003] Plates with inner right angles, like other customized furniture panels, use automatic cutting equipment for cutting and sawing. However, the current automatic cutting equipment for large-scale production of ...

AI Technical Summary

Problems solved by technology

[0003] Plates with inner right angles, like other customized furniture panels, use automatic cutting equipment for cutting and sawing. However, the current automatic cutting equipment for large-scale production of customized furniture panels uses cylindrical drills as cutting tools. There will be a circular chamfer with a radius approximately equal to the radius of the drill bit at the inner right angle intersection of the rear panel. This circular chamfer will cause problems that cannot be perfectly fitted during furniture installation.

[0004] At present, there is no special processing equipment for cutting and sawing this kind of inner right-angle arc chamfering. Using a general-purpose woodworking chamfering machine or double pull-saw requires cumbersome positioning operations on the board during the processing operation, and it is very easy to produce cracks after processing. When the surface of the panel is damaged, its processing quality and processing efficiency cannot meet the needs of mass production of customized furniture. At present, the usual way to deal with it is that the installer uses a knife to perform manual sawing on site, and the surface of the panel is often damaged and cut. If the corners are incomplete and cannot fit perfectly, or even damage the board, it will eventually cause the appearance of the furniture installation to be unsightly, and the board will be scrapped and re-ordered for production, which will seriously affect the user's consumption experience and increase the production and sales costs of customized furniture companies.
