Abstract

The invention discloses a vertical-type and connecting-rod-type intersecting line cutting head which comprises a main arm, a driven gear shaft and a pivot angle assembly installed on the driven gear shaft. The driven gear shaft is installed on the main arm through a bearing; a rotating speed reduction motor is installed on the main arm. A driving gear installed on the rotating speed reduction motor is meshed with a driven gear installed on the driven gear shaft to drive the driven gear shaft to rotate. A frame is fixed installed on the lower portion of the driven gear shaft through a round nut. The pivot angle assembly is installed on the frame. + / -90 degrees of an accurate pivot angle of a cutting torch is achieved through a four-connecting-rod mechanism of the pivot angle assembly. Mechanism motion needed by pipe cutting can be achieved through the combination of a rotating mechanism and the pivot angle assembly. The vertical-type and connecting-rod-type intersecting line cutting head guarantees a constant height position of a cutting point in the lifting process of the pipe; and because only a rotating shaft and a pivot angle shaft are linked, electrical control is relatively simple and programming workloads are substantially reduced.

Description

technical field

[0001] The invention relates to a vertical connecting rod type intersecting line cutting head, in particular to a vertical four connecting rod cutting head used for pipe intersecting line cutting, belonging to the technical field of pipe welding and cutting. Background technique

[0002] Cutting is the pre-welding process. At present, the intersecting line cutting equipment of the heavy-duty pipe prefabrication processing production line generally uses the cutting head of the horizontal four-bar linkage mechanism. The pipe bevel cutting can also be realized through software control, but the bevel angle is small, The shortcomings of large mechanism size and low reliability. In response to the development requirements of the industry, it is urgent to develop a cutting head with a relatively simple mechanical structure, low structural strength requirements for parts, and low cost to replace the existing products.
