H-shaped steel automatic cutting device for construction

Abstract

The invention discloses an automatic H-shaped steel cutting device for construction, which comprises a base, on which a first motor is fixedly connected with a same support, and a first feeding roller is rotatably connected, and a motor shaft at the front end of the first motor is connected with a first gear. The front end of the first feeding roller is fixedly connected to the second gear, and the first gear meshes with the second gear; the base is also connected to two second feeding rollers through the bracket rotation; the base is also connected to the top plate through the support rod, and the bottom of the top plate Two second slide rails are provided, and a moving frame is slidably connected between the second slide rails; two supporting plates are fixedly connected to the bottom of the moving frame, and a cutting knife is connected between the two supporting plates through rotating shafts. The invention drives the H-shaped steel to move periodically from left to right through the rotation of the feeding roller, and drives the cutting knife to move up and down through the rotation of the cam, thereby cutting the H-shaped steel. The feeding roller stops moving during cutting, making the cutting more stable.

Description

technical field [0001] The invention relates to a cutting device, in particular to an automatic cutting device for H-shaped steel used in construction. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used. [0003] The use of H-shaped steel in building construction often encounters situations that need to be cut. Now many construction units also use manual grooves as cutting machines to cut steel. Ordinary cutting machines are not easy to operate, and the cutting efficiency is low. The steel is easy to shift during t...

[0003] The use of H-shaped steel in building construction often encounters situations that need to be cut. Now many construction units also use manual grooves as cutting machines to cut steel. Ordinary cutting machines are not easy to operate, and the cutting efficiency is low. The steel is easy to shift during the cutting process. The cutting surface is not smooth enough, which will have an adverse effect on the use of steel
