Abstract

A rib removing knife of a multi-hole cable tube mainly comprises a knife holder, a blade, screws, a knife shank, a limit block and bolts. The knife shank, the blade with a bottom edge and a side edge, and the limit block provided with a mounting surface of a knife step and the limit block are installed and arranged on the knife holder to form a cutting tool, which is the rib removing knife. With the help of the cutting tool and a machine tool, ribs at the ends of a straight-wall type multi-hole cable tube can be removed, and only outer ribs are reserved. The outer ribs are shaped into socket-type sleeves through the processes of 'heating the ends of the tube' and 'expanding the openings of the tube, so that the straight-wall type multi-hole cable tube is shaped into a socket-type multi-hole cable tube, which needs no matching pipe connecting sleeve and can obviously reduce connection of the cable tube, and holes can not shrink or be blocked when the cable is welded, and the holes can not be in wrong connection when the cable tube is connected. The technical proposal provides necessary production technical conditions for producing socket-type cable tubes on a large scale, improving the structure of cable tubes, and enhancing the technology of cable tubes.

Description

Porous cable pipe removes the muscle cutter

Technical field:

The utility model relates to the telecommunications equipment and produces utensil, especially processes the production utensil of porous cable pipe product.

Background technology:

Existing cable tube is a kind of straight wall type tube material that directly takes off from make-up machine by fixed length in production procedure.Article two, the connection of tubing is each with pipe end opposite to each other insertion tube to connect two ports of cover accessory interconnective.This traditional straight wall type cable tube product and structure, owing to must the adapted pipe connect and overlap accessory and could connect, not only, obviously wasted and be at least the production material that a semicanal connects the cover accessory, and cable tube of every connection need engage twice, makes cable tube junction quantity and connect number of times obviously too much, to cable tube construct with burying brought inconvenience, increased workload, also can increase engineering cost, influence project quality.

A kind ofly be provided with the socket and spigot type cable tube of socket joint cover at pipe end, just can remedy cable tube of waste material, every connection that straight wall type cable tube product obviously exists need engage twice, can cause pore to dwindle during direct end face welding porous cable pipe with two pipe ends or deficiency such as obstruction.Because having only a pore and pore can not take place, straight wall type single hole cable tube connects inconsistent phenomenon, it is shaped to socket and spigot type single hole cable tube, than being easier to, " fixed length is drawn materials " operation just can form by " heating pipe end " and " the expansion mouth of pipe " technology as long as continue, but, pipe muscle branch to there be outer muscle and interior muscle, the pore branch has the straight wall type porous cable pipe in a plurality of sub-holes, be shaped to socket porous cable pipe, difficulty how by contrast, after must must removing the interior muscle of its pipe end, could continue " heating pipe end " and " the expansion mouth of pipe ", also not have at present the cutter and the equipment of removing internal ribs of porous cable pipe, therefore, product does not emerge so far as yet.

As seen, cable tube manufacturing enterprise is just pressing for a kind of dedicated tool that can remove internal ribs of porous cable pipe.

Summary of the invention:

The purpose of this utility model provides a kind of porous cable pipe that can remove straight wall type internal ribs of porous cable pipe and removes the muscle cutter, its scheme is such: cutter is provided with handle of a knife and blade, also be provided with tool rest and confinement block, adapted screw and bolt, the size of tool rest, by the junction in-scope of the junction formation of following outer muscle with internal ribs of porous cable pipe or the outer muscle inwall at place, junction is that the size of cutting the pin scope is determined, the size of confinement block, pressing the neutron hole of porous cable pipe determines, and, directly on tool rest, be provided with the crumb hole, the crumb outlet, bottom surface crumb import, side crumb import, opener groove/hole, the blade installed surface, screw, directly on blade, be provided with the edge of a knife, two screws, directly on confinement block, Yu Yiduan is provided with confinement block installed surface and cutter rank, and is provided with screw with the bottom surface that connects confinement block installed surface and confinement block; With handle of a knife, directly to be arranged at the end face of tool rest with the tool rest concentric; With the crumb hole,, be set directly on the tool rest with even distribution and up big and down small, upward logical crumb outlet, logical bottom surface crumb import down, the logical side crumb import of side; With blade, stretch to and slightly stretch out side crumb import, the bottom surface edge of a knife stretches to and slightly stretch out bottom surface crumb import with the side edge of a knife, with screw and screw, in the crumb hole, be fixed on the blade installed surface; With confinement block, fit and concentric with the bottom surface of tool rest with the confinement block installed surface, with bolt and screw, be fixed in the bottom surface of tool rest.

Owing to adopted such scheme, just cutter can be installed on the lathe with handle of a knife, blade is rotated with tool rest, the interior muscle of straight wall type porous cable pipe pipe end remove, outer muscle stays, proceed to " heating pipe end, the expansion mouth of pipe " technology and process thus, the outer muscle that stays is processed into the socket joint cover, pipe end is shaped to bell end, straight wall type porous cable pipe is shaped to socket porous cable pipe.This technical scheme, be large-scale production socket porous cable pipe product, concentrate and solved and to have connect cover by the adapted pipe, obviously reduce cable tube junction quantity, possess high strength and weldable performance, the big fastness of face of weld is good, pore/sub-hole can not take place during the welding cable tube to be dwindled or stops up and can not cause sub-hole to be connected many technical barriers such as inconsistent phenomenon, for promoting the cable tube technological layer, improve the cable tube product structure, necessary production specifications have been created, and, cutter structure is simple, make easily, cutting operation is easy, can not cause the cable tube production cost increases, and is to produce the indispensable production utensil of socket porous cable pipe product.
