Dedicated machine for slotting both ends of steel pipe

Abstract

The invention relates to a dedicated machine for slotting both ends of a steel pipe, belongs to the technical field of dedicated steel pipe processing equipment, and adopts the technical scheme that the dedicated machine adopts a bilaterally symmetrical structure; a left mobile trolley (10) is arranged on the left side of a base (1); a right mobile trolley (20) is arranged on the right side of the base (1); a linear guide rail is arranged on the base; the wheels of the left mobile trolley and those of the right mobile trolley are matched with the linear guide rail respectively; and a left axial sliding seat (11), a left main spindle box (12) and a left cutting torch (16) are arranged on the left mobile trolley. Adopting the both end cutting manner and the structural matching of a servomotor and a ball screw, the dedicated machine has the advantages that the efficiency is improved, and the precision is guaranteed; and a detection device can obtain the edge positions and the central positions of the ends of the steel pipe to slot a steel pipe with poor straightness, the requirement on the loading position of the steel pipe is lowered, and a radial adjusting sliding seat and a centering adjusting sliding seat are additionally arranged, so that the central positions of the steel pipe can be detected and tracked, a slotting surface and a cutting surface can be parallel to each other, and slotting precision is guaranteed.

Description

Technical field [0001] The invention relates to a special machine for steel pipe double-end slotting, which belongs to the technical field of special steel pipe processing equipment. Background technique [0002] At present, the steel pipe connection used in the steel pipe tower is mainly divided into two ways: flange and insert plate. The invention is a special equipment for grooving steel pipes connected to the plug-in board. In the background art, the grooving of steel pipes is usually realized by manual or simple device. The entire process includes manual marking and manual cutting, and it can only be operated at a single end. The main problems are: 1. Manual single-ended operation, work Low efficiency and high labor intensity; 2. The width and dimensional accuracy requirements of the slot cannot be guaranteed, resulting in difficulty in installation of the plug-in board or excessive gap, increasing the repair time or the workload of welding the plug-in board; 3. Both ends a...

Problems solved by technology

In the background technology, the grooving of steel pipes is usually done manually or with simple devices. The whole process includes manual scribing and manual cutting, and can only be operated at one end; the main problems are: 1. Manual single-end operation, work Low efficiency and high labor intensity; 2. The width and dimension accuracy requirements of the slot cannot be guaranteed, resulting in difficulty in installing the plug-in board or excessive gaps, increasing the rework time or the workload of welding the plug-in board; 3. Opening at both ends during single-ended operation The relative position of the groove is not easy to guarantee, resulting in the size deviation of the installation of the steel pipe tower; 4. The grooved cutting surface completed by manual or simple device is mostly centripetal, and the gap on one side after the inserting plate is installed is too large, which makes the welding workload of the inserting plate Increase
