High-performance composite board cutting machine and efficient cutting method

Abstract

The invention relates to a high-performance composite board cutting machine and an efficient cutting method.The two guide columns in the composite board cutting machine are fixed to the two ends of a guide column fixing base respectively, and the two ends of a blade fixing base are provided with guide column through holes and arranged on the guide columns in a sleeving mode through springs. A concentric circular arc groove is formed in the upper end face of the blade fixing base, the center line of the concentric circular arc groove in the vertical direction and the center line of the guide column in the vertical direction are not on the same line, a resistance reducing rolling shaft is arranged in the concentric circular arc groove, an eccentric driving pipe is located on the resistance reducing rolling shaft, and the two ends of the eccentric driving pipe are eccentrically connected with the guide column. A blade is connected to the lower end face of the blade fixing base, and the perpendicular line of the blade is the same as the center line of the concentric circular arc groove in the upper end face of the blade fixing base in the perpendicular direction. A pressing rod is connected with the eccentric driving pipe. The high-performance composite board cutting machine has the advantages that motion resistance of the eccentric driving pipe is reduced, manual cutting resistance is small, and hand feeling is easy; and secondly, the cutting of the blade and the pressing line of the highest bulge of the eccentric driving pipe are on the same vertical line, and the defects in the background technology are overcome.

Description

technical field [0001] The invention relates to a high-performance composite board cutting machine and a high-efficiency cutting method capable of forcing the blade in the composite board cutting machine to cut vertically downward, with small cutting resistance and easy hand feeling, and belongs to the field of composite board cutting machine manufacturing. Background technique [0002] In the structural design of the existing composite board cutting machine, the handle is set on the pressure rod, the pressure rod is connected to the drive rod in the middle, the drive rod and the eccentric drive rod, the two ends of the eccentric drive rod are respectively covered with rod sleeves, and the eccentric drive rod is sleeved along the rod. The inner diameter surface rotates, the two ends of the driving rod are connected with the column, the column is fixed on the base, the column is covered with a spring, the column on the spring is covered with a blade fixing seat, the blade is f...

Problems solved by technology

Its disadvantages: when the composite board needs to be cut, when the composite board located under the cutting edge of the blade knife is cut, the pressure rod drives the driving rod to rotate in the rod sleeve, and when the highest contact of the driving rod, the pressing line acts on the blade to fix it. When it is on the seat, its highest contacting downward pressure line (the largest point of eccentricity) does not act on the vertical centerline of the blade fixing seat, but deviates from the vertical centerline of the guide post by 12-13mm, which cannot form a vertical downward pressure. What is formed is The cutting force is inclined downward, so it is both laborious and impossible to form a vertical cut surface on the cutting edge surface, which affects the splicing accuracy between the cutting edge cutting surface and the cutting edge cutting surface
