Abstract

The invention belongs to the field of machining of sawing machines with circular saw blades and particularly discloses a circular saw used for cutting a door plank. The circular saw used for cutting the door plank comprises a motor and a disc. The center of the disc is connected with the output end of the motor. The circular saw further comprises multiple sawtooth units. A first cavity and a second cavity are formed in the disc. Each sawtooth unit comprises a hydraulic cylinder, a first piston rod, a second piston rod and a piston, wherein two overflow valves and two one-way valves from the second cavity to the hydraulic cylinder are arranged on the hydraulic cylinder. Liquid outlets of the overflow valves are connected with the first cavity. The pistons are located in the hydraulic cylinders. The first piston rods and the second piston rods are installed on the two sides of the pistons correspondingly. The first pistons are provided with first pressing parts with slants, the second piston rods are provided with second pressing parts with slants, and sawteeth are arranged on the first pressing parts and the second pressing parts. According to the scheme, the problem of difficult heat dissipation of the saw blades is solved.

Description

technical field [0001] The invention belongs to the field of sawing machine processing with circular saw blades. Background technique [0002] In the manufacturing process of the door, it is necessary to cut a large piece of wood into multiple planks, and a door panel cutting saw is required. Existing door panel cutting saws mostly adopt disc-shaped saw blades, which rotate at a high speed under the drive of a motor to perform cutting operations. The process of cutting wood with a saw blade is to crush the wood at the saw kerf into powder. Obviously, the narrower the saw kerf, the higher the utilization rate of the wood, and the more boards a single piece of wood can get. Taking the cutting of filler slats of blockboard as an example, the thickness of the filler slats is 11-14mm, while the thickness of the saw blade or saw kerf needs to be between 2.8-3mm, and the wood consumed by the saw kerf accounts for about 18-18mm of the total wood. 25%. The width of the kerf is det...
