On-line cutting equipment for heat preservation pipe production

Abstract

The invention relates to on-line cutting equipment for heat preservation pipe production. The on-line cutting equipment comprises workpiece clamping mechanisms, a cutting executing mechanism, a motor,a box body and a box body sliding rail; the box body sliding rail is arranged on a support frame of a heat preservation pipe one-step forming production line in parallel with the feeding direction ofworkpieces; the box body is match with the box body sliding rail; workpiece passing holes are arranged on that left end surface and the right end surface of the box body; a hollow shaft coaxial withthe workpiece passing holes is arranged at the end, entering the box body, of a workpiece; the workpiece clamping mechanisms are arranged on the outer side walls of the left end surface and the rightend surface of the box body, and are used for holding the workpieces tightly when the heat preservation pipe is cut off, so that the box body and the workpieces synchronously move axially; and the cutting executing mechanism is arranged inside the box body and is driven to operate by a motor arranged on the top cover of the box body, and the cutting executing mechanism is used for cutting off theheat preservation pipe workpiece at an insertion joint part. According to the equipment, the problem of cutting off the inserting joint parts of the heat preservation pipes on the continuous production line is solved, and the aim of synchronous operation with the heat preservation pipe one-step forming production line is achieved.

Description

technical field [0001] The invention relates to a thermal insulation pipe cutting device, in particular to an online cutting device suitable for one-step forming of thermal insulation pipe joints, and belongs to the technical field of thermal insulation pipes. Background technique [0002] The one-step molding process of the insulation pipe, that is, the extrusion of the plastic outer protection pipe and the foaming of the polyurethane insulation layer are completed at one time. one of the important methods. In the one-step forming process of the insulation pipe, in order to ensure the continuous supply of the steel pipe, it is necessary to connect the two sections of steel pipe through the plug joint; then the steel pipe enters the center hole at the head of the plastic extruder under the push of the conveying device, and when After the steel pipe protrudes from the other side of the center hole to the designed length, the plastic extruder extrudes the outer protective tub...
