Pipe layer sawing machine and method for pipe layer sawing machine to cut heads and tails

Abstract

The invention relates to a pipe layer sawing machine, in particular relates to a pipe layer sawing machine and a method for the pipe layer sawing machine to cut heads and tails, and belongs to the field of steel pipe production. Slope boards are fixedly mounted on a front end and a rear end of the pipe layer sawing machine of the present invention, respectively; a header is placed below each slope board. The pipe layer sawing machine avoids equipment faults and saves cost as traditional head-cutting shifting device and tail-cutting shifting device are replaced with the immobilized slope boards; after head cutting and tail cutting of steel pipes in a row, the actions of the head-cutting shifting device and the tail-cutting shifting device all are outward translation, downward turning-over, upward turning-over and backward translation, and the multiple actions may affect the rhythm of sawing; however, the immobilized slope boards are utilized to take the place of the head-cutting shifting device and the tail-cutting shifting device; the cut-off steel heads directly drop down on the slope boards when the steel pipes move forwards; and the production rhythm is accelerated.

Description

technical field [0001] The invention relates to a pipe gang saw, in particular to a pipe gang saw and a method for cutting the head and tail of the pipe gang saw, belonging to the field of steel pipe production. Background technique [0002] In the production of steel pipes, the capillary tubes rolled by various hot rolling units need to be cut into finished steel tubes of the size required by the user after being cooled by the cooling bed. The head end and the tail end of the capillary tubes rolled by each hot-rolling unit are irregular shapes, and pipe gang saws are needed to cut off the capillary ends of the head end and the tail end. After the pipe gang saw cuts off the heads of the rows of steel pipes, the cutting head transfer device will move the rows of pipe heads out of the saw machine, and then the flat plate of the cutting head transfer device will be turned down by an inclined angle through the hydraulic cylinder. The head will slide down to the pipe head colle...

AI Technical Summary

Problems solved by technology

After cutting the head and tail of a row of steel pipes, the movement of the head-cutting transfer device and the tail-cutting transfer device are all moved out - turned down - turned up - moved back, so that the movement will affect the rhythm of sawing.

In the process of steel pipe cutting, it is inevitable that the pipe head and sawdust will accumulate under the cutting head transfer device and tail cutting transfer device, which will cause damage to the hydraulic cylinder and oil pipe driving the head cutting transfer device and tail cutting transfer device, affecting The normal operation of the saw machine
