Polyline intersecting line cutting device for round pipe end

Abstract

The invention relates to the technical field of intersecting line cutting devices, in particular to a polyline intersecting line cutting device for a round pipe end. The polyline intersecting line cutting device comprises a bracket, a circumferential rotating mechanism and a linear sliding mechanism, wherein the circumferential rotating mechanism comprises a central flange barrel shaft, a round pipe clamp and a plurality of element spools; the central flange barrel shaft is arranged in the bracket; the round pipe clamp is arranged at the end part of the central flange barrel shaft; the element spools are annularly arranged on the outer side of the central flange barrel shaft; two end parts between two adjacent element spools are connected with transitional chains; the linear sliding mechanism comprises a parallel shaft, a driving rod, a fixed frame, a movable frame, an active wheel, an auxiliary wheel and a clamp mechanism; the driving rod is arranged on the fixed frame; the active wheel is sleeved on the driving rod and is butted against the transitional chains connected with one-ends of the element spools; the auxiliary wheel is arranged on the movable frame and is butted against the other ends of the element spools. The polyline intersecting line cutting device has the advantages of simple structure, low cost, mechanical programming function, convenience in use, high processing precision, convenience in transportation and carrying and the like.

Description

technical field [0001] The invention relates to the technical field of intersecting line cutting devices, in particular to a multi-segment intersecting line cutting device at the end of a round pipe. Background technique [0002] With the development of social economy, steel round pipes are widely used in building structures such as modern factory building trusses, warehouse trusses, gymnasium truss structures and stainless steel railings and handrails. Among them, intersecting line joints are one of the most common joint forms in steel circular pipe structural engineering. It is often necessary to cut the ends of interconnected steel circular pipes into intersecting openings so that the steel circular pipes can be closely connected with other structural parts. Resist for soldering. In the prior art, there are many types of numerical control devices capable of cutting the intersecting openings of steel pipes, but all of them have complex structures, large models, high cost,...

Problems solved by technology

In the prior art, there are many types of numerical control devices capable of cutting the intersecting openings of steel pipes, but all of them have complex structures, large models, high cost, inconvenient transportation and carrying, programming requires computer conversion, and operation is relatively inconvenient. To meet the needs of the mass market; at the same time, using templates to make intersecting lofting and scribing, and then cutting by hand, the size error of the production cut is too large, and it needs to be ground with a grinder, the overall quality is poor, and the labor cost is high. Low production efficiency
