Abstract

The invention relates to a cutting machine, and discloses a cutting machine with double oblique draw bars. The cutting machine comprises a base, a worktable, a rotary mechanism and a saw blade. A semicircular movable protective cover is arranged on the outside of the saw blade, an inner pressure plate and an outer pressure plate are arranged on two sides of the saw blade, the saw blade is sandwiched between the inner pressure plate and the outer pressure plate and is connected with a plastic gear box by a belt pulley transmission gear, the belt pulley transmission gear comprises a four-groove belt, and the inner pressure plate is clamped and embedded on the outer pressure plate. The cutting machine has the advantages that the saw blade can be positioned and clamped by a clamping and embedding type positioning and clamping device, accordingly, minor-axis sections can be shortened to the greatest extent, and a protective device can be narrowed to the greatest extent; the semicircular movable protective cover which is coaxially arranged is hinged onto a fixed protective cover, can move along with a cutting device and has a movable protective function; a front tank and a rear tank can be closed, and the rear tank is integrally connected with a motor shell, so that the gear box can be formed; the gear box and the motor shell are made of plastics, and accordingly the cutting machine is low in material consumption and cost and is light.

Description

technical field

[0001] The invention relates to a cutting machine, in particular to a double oblique stay rod cutting machine. Background technique

[0002] At present, cutting machines are widely used in the cutting and processing of various workpieces, and have made great progress. Existing cutting machines generally include a base, a workbench and a rotating mechanism arranged on the base, a saw blade supported and connected to the rotating mechanism for cutting workpieces, a pulley transmission for driving the saw blade to rotate, and a driving pulley transmission. The driving device can complete the cutting tasks of some profiles or workpieces to a certain extent, but the following problems generally exist:

[0003] One is that the saw blade positioning and clamping device includes an inner pressure plate and an outer pressure plate. The saw blade is set between the inner pressure plate and the outer pressure plate and is clamped, but the surfaces of the inner pressure...
