Abstract

The utility model relates to a long-tube big inch extrusion portable cutting machine tool. The output end of the utility model is fixedly connected with a chuck plate; the left end of a machine base is provided with a guideway; the guideway is provided with a cutter frame; the cutter frame is fixed with a rotating axis; the axial direction of the rotating axis equals to the turning of the chuck plate; the rotating axis is hinged with a circular disc squeeze cutter whose cutting edge is an acute angle; the cutter frame of the opposite side of the squeeze cutter is also fixed with a supporting mechanism. The utility model is suitable for cutting the long tube with big inch, and the utility model has the advantages of high efficiency, low cost, small occupied place and no pollution.

Description

The long tube heavy caliber pushes light cutting off machine

The utility model relates to a kind of cutting off machine, and particularly a kind of heavy caliber pushes light cutting off machine.

In the prior art, adopt traditional Methods of OFC-A for the cutting of Large Diameter Long Pipes, labour intensity is big always, and the occupied ground area is big, and efficiency is very low, and especially cut quality is lower, the otch deviation is bigger.Large Diameter Long Pipes application quantity in expressway construction is very big, along with the fast development of highway, and the needs of the incompatible development of prior art, existing gas cutting technology has waste gas to produce, and contaminated environment diminishes the healthy of operator.

The purpose of this utility model is to provide a kind of cutting efficiency height, and cut quality is good, and the long tube heavy caliber that helps environmental protection pushes light cutting off machine.

The purpose of this utility model realizes by following result: a kind of long tube heavy caliber pushes light cutting off machine, it is a horizontal type structure, is gearbox in the headstock, its output fixedly connected chuck, the support left end is equipped with guide rail, knife rest is housed on the guide rail, fixing a rotating shaft on the knife rest, rotating shaft axially identical, the crowded cutter of an articulated disk in the rotating shaft with turning to of chuck, its cutting edge is an acute angle, also is fixed with a supporting mechanism on the knife rest of the crowded relative side of cutter.

The squeezing action that the utility model utilizes disk to squeeze cutter is cut off pipe, and after the crowded cutter of disk was near pipe, the crowded cutter of disk can rotation be simultaneously diametrically to the pipe feed in rotating shaft, and pipe cuts off the most at last.In order to guarantee pipe stress balance when cutting, the utility model is provided with a supporting mechanism, is provided with roller in this mechanism, supports pipe with roller.Because cutting edge is an acute angle, the edge of the round steel pipe after therefore cutting off can form bevel for welding by nature, helps the carrying out of welding sequence.The utility model also is equipped with a centering frame, its objective is the concentricity that guarantees round steel pipe with supported at three point, and the roller on the centering frame is used for supporting round steel pipe, because the push rod adjustable length, the frame of therefore feeling relieved can be used to adjust the circle of different tube diameters.The utility model is compared with traditional handicraft and is raised labour efficiency 5 times, and its technology cost reduces, and it is little to take production site, non-environmental-pollution.

Fig. 2 is that the B of Fig. 1 is to view.

Fig. 3 is that the C of Fig. 1 is to view.

Fig. 4 is that the A of Fig. 1 is to view.

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment:

The utility model as shown in Figure 1 is horizontal type structure, is gearbox in the headstock, its output fixedly connected chuck 1, support 2 left ends are equipped with guide rail 3, and knife rest 4 is housed on the guide rail 3, are fixing a rotating shaft 5 on the knife rest 4, rotating shaft 5 axially identical with turning to of chuck 1, as shown in Figure 2, an articulated disk squeezes cutter 6 in the rotating shaft 5, as shown in Figure 5, its cutting edge is an acute angle, also is fixed with a supporting mechanism on the knife rest 4 of crowded cutter 6 relative sides.Described supporting mechanism is a support 7 that is fixed on the knife rest 4, fixing on this support 7 and going up rotating shaft and lower rotary shaft, and all articulated roller 8 in each rotating shaft, the axial line of upper and lower rotating shaft is on an inscribed circle.Fixing a centering frame 9 on the support between chuck 1 and the knife rest 4, centering frame 9 is an annular solid, opens one or three axis holes on it, and suit a push rod 10 of being fixed by jackscrew in each axis hole, and roller is equipped with in push rod 10 front portions.As shown in Figure 3, because the utility model cutting is long tube, therefore on its support, also fixing a plurality of carriages.
