Abstract

The utility model provides a thin wall pipe material revolving cut machine, which mainly comprises a power device, a knife disc, a hollow principal shaft, a tricycle feeding mechanism, and a pushing mechanism. The utility model is characterized in that: the pipe material to be cut is kept static, the knives rotate around the pipe material to be cut, and radially feed the cut pipe material. The utility model has the advantage in that: no cutting scraps produced, smooth flat and slightly inward shrunk incision, no need of chamfering and deburring; very suitable for cutting pipe material that has pipe assembly diameter requirement. In particular the utility model is suitable for cutting a plurality of stainless steel composite pipe, aluminum composite pipe, hard plastic pipe and normal thin wall metal pipe etc.

Description

The light-wall pipe peeler

The utility model relates to a kind of cutting equipment of thin-wall pipes, particularly a kind of light-wall pipe peeler.

The cutting machine of existing thin-wall pipes mainly contains with metal circular saw, or grinding wheel is the cutting machine of cutter, and it rotates at a high speed by saw blade, and cuts off tubing towards a direction feeding simultaneously.The deficiency of this kind cutting machine is: can produce smear metal during cutting, and splash everywhere, and contaminated environment not only, and scald human body easily, in addition, the tubing of being cut, wedge angle, burr are more, and otch is yielding.After the cutting, also need spend many times to remove to repair otch.In addition, caliber is had the tubing of matching requirements, the tubing of this cutting machine cutting often is difficult to meet the requirements.

The purpose of this utility model is to propose not produce smear metal when a kind of thin-wall pipes is cut, and otch is smooth, smooth, and need not the chamfering deburring, and meets the light-wall pipe peeler of Equipment Requirement.

Can realize the purpose of this utility model by following technical proposals: a kind of light-wall pipe peeler, comprise power set, it is characterized in that it mainly is made of cutterhead, hollow spindle, three ring feed mechanisms, propulsion plant, hollow spindle is fixed on two interior bearings of bearing block, propulsion plant, three ring feed mechanisms are enclosed within on the hollow spindle successively, hollow spindle and cutterhead are fixedly connected, fix three forks by rotating shaft is uniform in the cutterhead end face, wherein two forks are equipped with supporting rollern, and another fork is equipped with the rotary-cut cutter.Three ring feed mechanisms are to be made of three rings that are nested, and by two relative pin pin joints, arranging of four pins is crosswise between the alternate ring.One lever is by the hole on the cutterhead, and an end is pressed on the fork, and the other end leans against on the end face of three ring feed mechanism outer shrouds.

Propulsion plant is made of screw-casing, end face thrust bearing and the steady pin that is located on the bearing block, screw-casing by hollow shaft sleeve on bearing block, the end face thrust bearing is enclosed within on the hollow shaft successively, screw-casing is provided with handle and inclined-plane depression, the inclined-plane of this inclined-plane depression is with guide near steady pin on the steady pin.

Between fork and cutterhead inward flange, connect a back-moving spring.

The utility model is because it is to adopt around being rotated by the Pipe Cutting material and by the cutting mode of cutter radial extruding, thereby makes it have following effect: 1, in the cutting process, do not produce smear metal, and pollution-free.2, smooth, the smooth and slightly inwardly contraction of otch is specially adapted to the tubing that caliber has matching requirements.3, because of no wedge angle and burr, compare with existing cutting machine, saved the operation of chamfering and deburring, saved the man power and material.

Below in conjunction with accompanying drawing the utility model is further set forth

Accompanying drawing 1, be half sectional view of the present utility model.

Accompanying drawing 2, be the schematic diagram of cutterhead in the utility model.

Accompanying drawing 3, be in the utility model three the ring feed mechanisms schematic diagram (broken section)

Referring to accompanying drawing 1,2,3, the inner, both sides of bearing block 1 respectively is provided with bearing 2, and hollow spindle 3 is fixed on the two bearings 2.The left end of hollow spindle 3 connects with power set, and screw-casing 4 is enclosed within the right-hand member of bearing block 1 by hollow spindle 3.Screw-casing 4 is provided with inclined-plane depression 5 and handle 6, is provided with a steady pin 7 near the bearing block 1 at the place, inclined-plane of inclined-plane depression 5, for being with guide on the steady pin 7 of reducing friction.End face thrust bearing 8 and three ring feed mechanisms 9 are enclosed within on the hollow spindle 3 successively, three ring feed mechanisms 9 are made of interior ring, middle ring, three rings of outer shroud, in between ring and the middle ring by two relative pin pin joints, middle ring and outer shroud are by two relative pin pin joints, these 4 pin shaped are crosswise.Cutterhead 10 is fixedly connected with hollow spindle 3 right-hand members, fixes three forks 11 by rotating shaft is uniform in the cutterhead end face.Wherein in two forks 11 supporting rollern 12 is housed, on another fork 11 rotary-cut cutter 13 is housed, lever 14 is by the hole on the cutterhead, and its right-hand member is near being pressed on the fork 11, and its left end encircles on the outer shroud end face of feed mechanisms 9 near three.Between the inward flange of fork 11 and cutterhead 10, be associated with spring 15, be stamped end cap 16 at the right-hand member of cutterhead 10.

Workflow of the present utility model is: power set drive the hollow spindle rotation, hollow spindle drives the cutterhead rotation, manual or motor-driven effect handle makes the screw-casing rotation, screw-casing is in rotary course, because inclined-plane and the steady pin effect on the bearing block in the depression on the screw-casing make spiral interplanting axially-movable.Thereby the interior rings that promote end face thrust bearing and three ring feed mechanisms are done axially-movable, and when inner axle during to feeding, middle ring, outer shroud be axial feed simultaneously, promotes lever and also fork is rotated around the shaft, makes rotary-cut cutter and supporting rollern radial feed simultaneously.After two rollers touch tube wall, its resistance reacts on outer shroud, and ring continued to produce axial feed in the rotation of screw-casing made at this moment, because three rings adopt the cross pin joint, produce the balance feeding of floating, the fork that two supporting rollerns promptly are housed stops radial motion, and the fork that cutter is housed is under the effect of outer shroud, continue radial motion, end until cutting off the pipe material.Cutting pipe material back fork playbacks under the effect of spring.This machine is applicable to the cutting of all kinds of stainless steel composite pipes, aluminium composite pipe, hard plastic tube and normal thin wall metallic pipe material.
