A high-efficiency steel bar cutting machine

Abstract

The invention discloses a high-efficiency steel bar cutting machine. Its structure includes a pressing handle, a rotating mechanism, a fixed seat, a placement plate, and a cutting hole. The rotating mechanism is provided with a cleaning device, a protective shell, and a cutting blade. On the left and right sides of the blade, the spring rod shrinks the scraper to avoid friction between the scraper and the cutting blade at all times, preventing the scraper from being damaged too quickly, and the magnetic blocks on the upper and lower sides of the spring rod keep the spring rod in balance, scraping The cleaning mechanism at the lower end of the cleaning mechanism makes the cutting blade more sharp. The inclined cleaning plate is stretched and stretched through the second elastic rod at the right end of the fixed rod, which rubs against the cut of the cutting blade, and the cleaning rod on the cleaning plate acts on the cut of the cutting blade. Force, to avoid the expansion of the lateral area of ​​the cutting blade surface, block cleaning block to scrape off the swarf residue attached to the side of the cutting blade, to prevent the swarf residue from solidifying on the side of the cutting blade after cooling, and to prevent the cutting blade from slipping on the surface of the steel bar when cutting.

Description

technical field [0001] The invention relates to the construction field, in particular to a high-efficiency steel bar cutting machine. Background technique [0002] The steel bar cutting machine is used for the fixed-length cutting of steel bars, and is suitable for ordinary carbon steel, hot-rolled round steel and screw steel in various reinforced concrete in construction engineering. It has the advantages of small size, light weight, strong and reliable, and is convenient for construction However, when the previous equipment cuts the steel bar, the steel bar will rub against the cutting blade, sparks will be sputtered, and part of the high-temperature chip residue will be adhered to the splashed sparks. Continuous contact with oxygen causes its surface to oxidize and the internal temperature continues to be high, and the flying sparks will change the jet direction with the airflow of the cutting blade. Since there is a certain gap between the cutting blade and the baffle, t...

[0002] The steel bar cutting machine is used for the fixed-length cutting of steel bars, and is suitable for ordinary carbon steel, hot-rolled round steel and screw steel in various reinforced concrete in construction engineering. It has the advantages of small size, light weight, strong and reliable, and is convenient for construction However, when the previous equipment cuts the steel bar, the steel bar will rub against the cutting blade, sparks will be sputtered, and part of the high-temperature chip residue will be adhered to the splashed sparks. Continuous contact with oxygen causes its surface to oxidize and the internal temperature continues to be high, and the flying sparks will change the jet direction with the airflow of the cutting blade. Since there is a certain gap between the cutting blade and the baffle, the airflow flows here Cyclone air flow will be formed when the steel bar is cut, so that the high-temperature chip residue in the spark will reattach to the surface of the cutting blade along with the air flow, so that the lateral area of ​​the cutting blade surface will expand, and when the steel bar is cut, the force-bearing area of ​​the cross-sectional surface of the steel bar will become larger. Difficult to cut, causing the blade to slip on rebar surfaces
