Description

Technical Field

[0001] The present invention belongs to the technical field of section steel processing and transformation, and particularly relates to a multi-functional integrated machine for section steel cutting and punching. Background Art

[0002] For the bolt connection of spliced section steel, it is necessary to cut and punch the section steel and gusset plates. For traditional section steel cutting, a manual-held plasma cutting machine is used for cutting. During the cutting process, there are often problems such as the safety of operators, poor manual cutting accuracy, and low efficiency. For traditional section steel hole opening, a manual-held oxygen and acetylene welding machine is used to burn the section steel holes. Similarly, there are problems such as the safety of operators, poor manual hole opening accuracy, and low efficiency.

[0003] Poor accuracy in manual cutting and hole opening will result in misalignment of bolt holes and uneven interfaces, seriously affecting the quality of section steel splicing. Even if mechanical construction is used for section steel cutting and punching, it usually needs to be carried out on different equipment, and the secondary transfer of materials will greatly increase the cost of section steel splicing. Therefore, there is an urgent need for a construction equipment and method for bolt connection and splicing of section steel that is efficient, simple, safe, and economical. Summary of the Invention

The rotating arm is welded on the bearing race, and the height of the race is fixed by bolts up and down. The rotating arm and the bearing race can rotate along the bearing. The punching device is installed on the rotating arm. By turning the rotating handle at the end, the punching device can move along the rotating arm through a long screw. The punching device consists of an electric punching machine and a drill bit, and the up and down movement of the drill bit can be adjusted by turning the rotating handle. An automatic water supply and cooling pipeline is installed on the punching device and supplied with water by the circulating water cooling device. In addition, the start switch power supply of the punching device and the switch power supply of the circulating water cooling device are integrated at the end of the rotating arm to enhance the controllability of the punching device. At the same time, a table lamp is installed on the rotating arm to increase lighting.

[0006] On both ends of the integrated machine frame beside the section steel punching working device, seat steel plates for the section steel cutting working device are welded. The main track is connected to the seat steel plates at both ends of the integrated machine frame by bolts. A secondary track perpendicular to the main track is installed on the main track.
