Method for machining boards by using linear saw and numerical control sawing machine equipment

Abstract

The invention discloses a method for machining boards by using a linear saw and numerical control sawing machine equipment. The numerical control sawing machine equipment comprises two bearing mechanisms (11, 12) respectively connected with two ends of a saw (80), at least one control motor (20) for adjusting the distance between the two bearing mechanisms (11, 12), and a pair of vibration motors(31, 32) for driving the saw (80) to vibrate, wherein the distance between the two bearing mechanisms (11, 12) is adjusted through the control motor (20) based on monitored torque change of the control motor (20). The board machining method and the numerical control sawing machine equipment can reduce transverse bending or twisting deformation of the linear saw during machining, relatively stabilize the position precision in transverse machining of the linear saw, and improve the position precision and the perpendicularity of gaps in reciprocating cutting of the linear saw and the machining quality of the gaps.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a method for processing plates with a linear saw and numerically controlled sawing machine equipment. Background technique [0002] At present, the cutting dies on the market mainly include wooden cutting dies, plastic cutting dies, iron or aluminum cutting dies, acrylic cutting dies, etc., but the most important cutting dies are wooden cutting dies. The wood cutting die is to open a knife-mounting gap on a wooden board of a certain thickness according to the size of the die-cutting blade according to the shape of the product to be die-cut. To connect the two sides of the knife-mounting gap to prevent it from falling off, and then insert the blade into the knife-mounting gap. The width of the gap on the knife template should adapt to the width of the die-cutting knife. The two sides of the gap wall are closely matched with the blade to achieve a fixed The role of the die cutter. ...

Problems solved by technology

Its advantage is that it can provide a relatively constant tension to buffer the periodic fluctuation of the tension, but the disadvantages are also very obvious, mainly: due to the elastic components or damping devices, such as oil cylinders, cylinders, extension springs, compression springs and other components cannot actively adjust the linearity The pulling force at both ends of the saw, and the pulling force they generate is not easy to actively adjust in the reciprocating motion of the linear saw, it is very difficult to adjust, and the adjustment is not precise and very vague

It is not possible to accurately realize the active real-time adjustment of the pulling force of the linear saw in real time, so it can only passively buffer the periodic fluctuation of the pulling force within a certain range, and due to the high-speed reciprocating motion of the linear saw and vibrating components, as well as elastic components Or the elastic or damping performance of the damping device itself, so this passive buffer also has hysteresis

[0017] All in all, the use of elastic elements or damping devices can only passively and hysteresisly buffer the periodic fluctuations of tension within a certain vague range, so the use of elastic elements or damping devices (such as oil cylinders, cylinders, extension springs, compression springs) etc.) to realize the above-mentioned scheme of controlling the tension force of the linear saw, the periodical change fluctuation amplitude of the tension is not well controlled, and the amplitude of the fluctuation is relatively large, so that before using the linear saw for processing, it is necessary to straighten and tension the linear saw. The pre-loaded tension should not be too large, otherwise the fluctuation of the tension during processing will easily exceed the maximum tensile strength limit of the linear saw

Since the pre-loaded tension of the linear saw is not large and the fluctuation range is very large, this greatly affects the cutting precision and quality of the linear saw, so that the current cutting precision of the linear saw has always been in a low state and level.
