Abstract

The invention discloses a floatable device for removing inner burrs of a steel tube. The device is characterized by being mainly composed of a cutter holder (1), a cutter bar (2), an oscillating bar (3) and a spring pressing mechanism, wherein one end of the oscillating bar (3) is hinged to a point B of a vertical cutter rest (9) of a pipe cutter machine, the other end of the oscillating bar (3) is hinged to a point A in the middle of the cutter bar (2), one end of the cutter bar (2) is connected with the cutter holder (1), a cutter (4) is arranged on the cutter holder (1), the other end of the cutter bar (2) is connected with one end of a pull bar (5), the other end of the pull bar (5) is hinged to the oscillating bar (3), a spring (6) is installed on the pull rod (5), the spring pressing mechanism is composed of the pull bar (5), the spring (6) and a pin shaft (7), and all the components form a lever mechanism. The cutter can float along with the bounce of inner edges and corners of tube ends in the cutting process under the action of the spring, and therefore the loss of the cutter can be reduced, the cutter replacement time can be shortened, and the machining quality of the steel tube and the efficiency of equipment can be improved. The device is simple in structure, reliable and practical.

Description

A kind of relocatable steel pipe is beaten inner burr device

Technical field:

The present invention relates to steel-tube finishing technical field, is the device that a kind of relocatable steel pipe is beaten inner burr specifically.

Background technology:

Pipe cutting machine is the capital equipment that seamless steel pipe finishing is produced, and when steel pipe is delivered into after pipe cutting machine, the chuck of main spindle box of tube-cutting machine front end clamps steel pipe and drives steel pipe to rotate together.Horizontal tool head before chuck completes the cut-out to steel pipe tube head, and after tube head cuts off, and by rail head, completes adverse slope mouth inside and outside pipe end, the burr that the device of falling internal groove stays while also can be used to dozen to go steel pipe to be cut off on pipe end inside corner.Due to circular runout and the either large or small ovality of steel pipe inner wall of pipe cutting machine main shaft and chuck, steel pipe is in by the process of chuck clamping rotation, and pipe end inside corner can be beated along pivot.Make the cutter of inner burr because can not float along with beating of inside corner, the cutting depth of fixing a cutting tool at circumference is just different, in the shallow place of cutting, often do not fall burr, in the place that cutting is dark, just often gnaw cutter and collapse cutter, thereby cutter consumption is increased, crudy is poor, affects the normal production of pipe cutting machine.

Summary of the invention:

The object of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of relocatable steel pipe to beat inner burr device; The problem that mainly solves that existing pipe cutting machine beats that the cutter of inner burr device cannot float, cutter loss is large, steel pipe crudy is poor etc.

Technical scheme of the present invention is: a kind of relocatable steel pipe is beaten inner burr device, its special character is, it is mainly by tool rest, knife bar, swing arm and spring compression mechanism form, swing arm one end is point articulated on pipe cutting machine rail head at B, the other end and knife bar middle part A are point articulated, knife bar one end connects tool rest, on tool rest, establish cutter, one end of knife bar other end cylinder lever connecting rod, pull bar uses bolt to fix through bearing pin and in the outside of bearing pin, bearing pin rotates in the pin-and-hole of knife bar, the other end of pull bar is hinged by bearing pin and swing arm, mounting spring on pull bar, by pull bar, spring, bearing pin forms spring compression mechanism, Driven by Hydraulic Cylinder swing arm on rail head, thus drive knife bar and tool rest to rotate around B point, bearing pin and knife bar are hinged, thereby make the knife bar can be around A spot wobble under the effect of spring force.

Further, on described swing arm, establish jackscrew, adjust the inclination angle that jackscrew can fine-adjustable tool bar, thereby adjust the cutting position of cutter.

A kind of relocatable steel pipe of the present invention is beaten inner burr device and is compared with the prior art had outstanding substantive distinguishing features and marked improvement: 1, cutter has float function in lever system, can make cutter along with beating of pipe end inside corner, float when cutting, solve cutter and do not floated the processing that causes not exclusively and the problem of gnawing cutter, collapsing cutter, thereby reduced cutter consumption and replacing time, improved steel pipe crudy and equipment efficiency; 2, this device is arranged on the rail head of existing equipment, by original Driven by Hydraulic Cylinder, does not need other supporting driving mechanism, simple in structure, reliable and practical.

Accompanying drawing explanation:

Fig. 1 is that device of the present invention is arranged on the design sketch on pipe cutting machine rail head;

Fig. 2 is device cutaway view of the present invention;

Fig. 3 is that device of the present invention is arranged on the graphics on pipe cutting machine rail head;

Fig. 4 is device graphics of the present invention.

The specific embodiment:

For Comprehension and Implementation better, below in conjunction with accompanying drawing, provide specific embodiment and describe the present invention in detail; Illustrated embodiment is only for explaining the present invention, not for limiting the scope of the invention.

Embodiment 1, referring to Fig. 1,2, swing arm 3 one end are point articulated at knife bar 2 middle parts at A, knife bar 2 one end are tool rest 1 fixedly, on tool rest 1, fixed cutting tool 4, swing arm 3 other ends are point articulated on pipe cutting machine rail head 9 (being a part for rail head in diagram) at B, by the Driven by Hydraulic Cylinder swing arm 3 on rail head 9, thereby drive knife bar 2 and tool rest 1 to rotate around B point; By pull bar 5 springs 6, bearing pin 7, form spring compression mechanism, one end of pull bar 5 is hinged by bearing pin and swing arm 3, the other end of pull bar 5 passes bearing pin 7 and fixes by nut and knife bar 2 other ends, bearing pin 7 can rotate in the pin-and-hole of knife bar 2, bearing pin 7 is hinged with knife bar 2, thereby can make knife bar 2 under the effect of spring force around A spot wobble, spring 6 is arranged on pull bar 5, by the upper end of tool rest 1 to extrapolation; Jackscrew 11 is installed on swing arm 3,, adjust the inclination angle that jackscrew 11 can fine-adjustable tool bar 2, thereby adjust the cutting position of cutter 4, it is depressed on the pipe end inside corner that rear knife edge is just in time in steel pipe 10.

A kind of relocatable steel pipe of the present invention is beaten inner burr device, before work, first adjust the position of rail head 9, finely tune jackscrew 11 simultaneously, cutter 4 is just in time pressed on the pipe end inside corner of steel pipe 10, and under the effect of spring 6, there is suitable thrust, so that cutter 4 can be beated and float along with the pipe end inside corner of steel pipe 10 in working angles, cutter 4 has suitable strength to be pressed on inside corner all the time, thereby guarantees that the cutting degree on circumference is basically identical; By the hydraulic cylinder on pipe cutting machine rail head 9, drive swing arm 3, knife bar 2 and tool rest 1, make to be arranged on the pipe end inside corner of the cutter 4 contact steel pipes 10 on tool rest 1, realize and beat inner burr.
