Problems solved by technology

[0002] Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular. A large number of steel bars are needed in construction, but sometimes the length of the steel bar is too long and it needs to be cut to obtain the steel bar that meets the length requirements. Currently, the steel bar Most of the advanced cutting devices are constant-speed cutting, that is, the feed speed during cutting is constant, but due to the cutting, the contact area between the cutting blade and the steel bar will change. When the contact area becomes larger, the gap between the cutting blade and the steel bar will change. The friction force becomes larger, and using the same feed rate all the time may cause damage to the cutting blade or the blade is stuck

Abstract

The invention discloses a steel bar cutting device capable of automatically adjusting the feeding speed. The steel bar cutting device comprises a machine body, a cutting mechanism is arranged in the machine body, the cutting mechanism comprises a cutting block fixedly connected in the machine body, a feeding motor is fixedly connected in the cutting block, the feeding motor controls a screw rod, the screw rod is in threaded connection with a limiting block, and the limiting block is in sliding connection with the cutting block. When the steel bar cutting device is used for cutting a steel bar, the working speed of the feeding motor is adjusted by extruding a sensing block through a moving block, so that the working speed of the feeding motor is changed along with the change of the contact area of a cutting blade and the steel bar, the phenomenon that the blade is stuck or damaged due to the too large contact area is avoided, besides, the horizontal distance between the sensing block and the moving block can be automatically adjusted according to the diameter of the steel bar to be cut, the steel bar cutting device can be suitable for cutting steel bars with different diameters, and the applicability is wider.

Description

technical field [0001] The invention relates to the related field of steel bar cutting, in particular to a steel bar cutting device that automatically adjusts the feed speed. Background technique [0002] Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular. A large number of steel bars are needed in construction, but sometimes the length of the steel bar is too long and it needs to be cut to obtain the steel bar that meets the length requirements. At present, the steel bar Most of the advanced cutting devices are constant-speed cutting, that is, the feed speed during cutting is constant, but due to the cutting, the contact area between the cutting blade and the steel bar will change. When the contact area becomes larger, the gap between the cutting blade and the steel bar will change. The friction force becomes larger, and using the same feed rate all the time may cause damage to the cutting blade or t...
