Description

Inner burr device beaten by a kind of relocatable steel pipe

Technical field:

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

Background technology:

Tube cutter is the major equipment that weldless steel tube finishing is produced, and after steel pipe is delivered into tube cutter, the chuck of main spindle box of tube-cutting machine front end clamps steel pipe and drives steel pipe to rotate together. Horizontal knife rest before chuck completes the cut-out to steel pipe tube head, and after tube head cuts off, completes to fall inside and outside pipe end groove by vertical knife rest, and the device of falling internal groove also can be used to beat the burr stayed on corner angle in pipe end when going steel pipe cut-off. Due to the diameter run-out of tube cutter main shaft and chuck and the either large or small ovality of steel pipe inwall, steel pipe is in the process rotated by chuck clamping, and in pipe end, corner angle can be beated along rotation center. Make the cutter of inner burr because can not float along with interior beating of corner angle, just different at the depth of cut of circumferentially cutter, burr is not often fallen in the shallow place of cutting, the place dark in cutting is just often gnawed cutter and collapses cutter, thus cutter consumption is increased, processing quality is poor, affects the normal production of tube cutter.

Summary of the invention:

It is an object of the invention to overcome the deficiency of above-mentioned prior art, it is provided that inner burr device beaten by a kind of relocatable steel pipe; Mainly solve that existing tube cutter beats inner burr device cutter cannot float, cutter loss is big, the problem of steel pipe processing quality difference etc.

The technical scheme of the present invention is: inner burr device beaten by a kind of relocatable steel pipe, its special character is, it is primarily of tool rest, knife bar, swing bar and spring application mechanism composition, swing bar one end point articulated on the vertical knife rest of tube cutter at B, in the middle part of the other end and knife bar, A is point articulated, knife bar one end connects tool rest, tool rest is established cutter, the knife bar the other end connects one end of pull bar, 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 with swing bar by bearing pin, mounting spring on pull bar, by pull bar, spring, bearing pin forms spring application mechanism, Driven by Hydraulic Cylinder on vertical knife rest swings bar, thus drives knife bar and tool rest to rotate around B point, bearing pin and knife bar are hinged, thus knife bar can be swung around A point under spring force.

Further, jackscrew established by described swing bar, adjustment jackscrew can the inclination angle of fine-adjustable tool bar, thus 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 cut time along with pipe end in beating of corner angle and float, solve the do not float processing that causes of cutter not exclusively and to gnaw cutter, collapse the problem of cutter, thus decrease cutter consumption and replacing construction, it is to increase steel pipe processing quality and equipment efficiency; 2, this device is arranged on the vertical knife rest of original equipment, by original Driven by Hydraulic Cylinder, it is not necessary to supporting driving mechanism in addition, structure is simple, reliable and practical.

Accompanying drawing illustrates:

Fig. 1 is the design sketch that the device of the present invention is arranged on the vertical knife rest of tube cutter;

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

Fig. 3 is the three-dimensional plot that the device of the present invention is arranged on the vertical knife rest of tube cutter;

Fig. 4 is the device three-dimensional plot of the present invention.

Embodiment:

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

Embodiment 1, see Fig. 1,2, bar 3 one end will be swung point articulated in the middle part of knife bar 2 at A, tool rest 1 is fixed in knife bar 2 one end, fixed cutting tool 4 on tool rest 1, bar 3 the other end will be swung point articulated on the vertical knife rest of tube cutter 9 (diagram being a part for vertical knife rest) at B, and swing bar 3 by the Driven by Hydraulic Cylinder on vertical knife rest 9, thus drive knife bar 2 and tool rest 1 to rotate around B point; Spring application mechanism is formed by pull bar 5 spring 6, bearing pin 7, one end of pull bar 5 is hinged with swing bar 3 by bearing pin, the other end of pull bar 5 is through bearing pin 7 and is fixed by nut and knife bar 2 the other end, bearing pin 7 can rotate in the pin-and-hole of knife bar 2, bearing pin 7 is hinged with knife bar 2, such that it is able to make knife bar 2 swing around A point under spring force, spring 6 is arranged on pull bar 5, by the upper end of tool rest 1 to extrapolation; Jackscrew 11 is installed swinging on bar 3, adjustment jackscrew 11 can the inclination angle of fine-adjustable tool bar 2, thus adjust the cutting position of cutter 4 so that it is the lower rear knife edge of pressure is just in the pipe end of steel pipe 10 on corner angle.

Inner burr device beaten by the relocatable steel pipe of one of the present invention, first the position of vertical knife rest 9 is adjusted before work, finely tune jackscrew 11 simultaneously, cutter 4 is made just to be pressed in the pipe end of steel pipe 10 on corner angle, and under the effect of spring 6, there is suitable snap-in force, so that cutter 4 can be beated and float along with corner angle in the pipe end of steel pipe 10 in working angles, namely cutter 4 has suitable strength to be pressed on interior corner angle all the time, thus ensures in cutting degree circumferentially basically identical; By the hydro-cylinder on the vertical knife rest 9 of tube cutter, drive and swing bar 3, knife bar 2 and tool rest 1, make the cutter 4 being arranged on tool rest 1 contact corner angle in the pipe end of steel pipe 10, it is achieved to beat inner burr.
