Abstract

The utility model provides a curved surface cutting tapping machine applicable to tapping on a curved surface, which comprises a magnetic seat, a fixed rod, a cross beam used to connect the magnetic seat and the fixed rod, and a ruler guide rod with a cutting nozzle fixed on the end, a rotating part is connected with the fixed rod in a rotating way; the ruler guide rod and the rotating part are connected in a sliding and rotating way in a plane in parallel with the axial direction of the fixed rod; the cross beam is divided into two sections capable of relatively sliding, and the magnetic seatis provided with an adjusting device used to adjust the distance of the bottom relatively from a supporting surface. When in use, the adjusting device can lead the magnetic seat to be quite stably positioned on the curved surface and an inclined surface; and by dividing the cross beam into the two sections capable of relatively sliding, the distance scope for the fixed rod and the cutting nozzleto be lifted up and down is increased so as to adapt to the inclination status of the curved surface and the inclined surface.

Description

Curved surface cutting tapping machine

Technical field

The utility model relates to a kind of curved surface cutting tapping machine that carries out perforate on curved surface with cutting mode.

Background technology

The emerging clear special steel 3200m in Jiangyin ³The perforate of water-cooling wall, throat armour, furnace bottom water cooling tube, coal gas sealing cover is 5136 altogether on the last furnace shell, wherein 450 of perforates at the construction field (site), wherein 328 of perforates on the water-cooling wall, Φ 135mm, 128 of furnace bottom water cooling tube perforates, Φ 120mm, 68 of thermocouple holes, Φ 33mm, furnace shell thickness is between 80mm-50mm, for reducing the stress that the furnace shell perforate produces, mechanical perforate is all adopted in the on-the-spot perforate of furnace shell.Because furnace shell installs, most of furnace shell is the garden conical surface (local is the face of cylinder), and perforate is carried out on curved surface, and existing used in the market tapping machine as Figure 1-3, crossbeam 1 connects magnet base 2 and fixed bar 3, and tumbler 4 is rotatably connected on the fixed bar 3; The end of scale guide rod 5 is fixed with cutting torch 6; The scale guide rod becomes to slide in being parallel to the axial plane of fixed bar with tumbler and is rotationally connected.During use, magnet base 2 is fixed on the supporting surface.This device is more convenient in the plane perforate, and the perforate difficulty is bigger on curved surface.

The utility model content

The purpose of this utility model provides a kind of curved surface cutting tapping machine that is adapted at the curved surface perforate.

This curved surface cutting tapping machine comprises magnet base, fixed bar, and the crossbeam of connection magnet base and fixed bar, a tumbler is rotatably connected on the fixed bar; The end is fixed with the scale guide rod of cutting torch; The scale guide rod becomes to slide in being parallel to the axial plane of fixed bar with tumbler and is rotationally connected; Crossbeam is divided into two sections that can slide relatively; Magnet base is provided with and is used to regulate the adjusting device of its bottom with respect to the supporting surface distance.

When using the utility model, can be by adjusting device so that magnet base more firmly is positioned on curved surface and the inclined-plane; By being divided into, crossbeam can slide relatively two sections, but the increase of the distance range of fixed bar and cutting torch oscilaltion, to adapt to the situation that curved surface and inclined-plane tilt.

As improvement, adjusting device is a bolt.Regulate magnet base with respect to the supporting surface distance with bolt, simple and practical, cost is low.

As improvement, respectively be fixed with slide plate on the opposite face of two sections crossbeams, have guide groove on the slide plate, the guiding fishbolt passes two guide grooves on the slide plate.

The beneficial effects of the utility model: can perforate on curved surface and inclined-plane, simple in structure, light portable.

The specific embodiment

Referring to Fig. 4-7, this curved surface cutting tapping machine comprises magnet base 2, fixed bar 3, the crossbeam 1 of connection magnet base and fixed bar.Crossbeam is divided on the opposite face of two

sections

11,12, two sections crossbeams that can slide up and down relatively and respectively is fixed with

slide plate

13,14, has guide groove 15 on the slide plate, and guiding fishbolt 16 passes two guide grooves 15 on the slide plate.Be provided with two in close fixed bar one side of magnet base 2 and be used to regulate the adjusting bolt 8 of its magnet base bottom with respect to the supporting surface distance.Regulate bolt 8 by rotating, can be so that stable being fixed on the skew surface 9 that is cut of magnet base.

One tumbler 4 is rotatably connected on the fixed bar 3; Scale guide rod 5 ends are fixed with cutting torch 6.Scale guide rod 5 becomes to slide in being parallel to the axial plane of fixed bar with tumbler 4 and is rotationally connected, and this scale guide rod 5 slides with 4 one-tenth of tumblers and rotation connection structure belongs to prior art, no longer specifically describes.Scale guide rod 5 becomes to slide in being parallel to the axial plane of fixed bar with tumbler 4, when scale guide rod 5 slides with respect to tumbler 4, can change the distance of cutting torch 6 to fixed bar, has also just changed the aperture that is cut.Scale guide rod 5 becomes to be rotationally connected in being parallel to the axial plane of fixed bar with tumbler 4, when scale guide rod 5 rotates with respect to tumbler 4, can change the distance of cutting torch to cut surface.

The emerging clear special steel 3200m in Jiangyin ³The blast furnace engineering is to carry out perforate after furnace shell installs, and furnace shell is the thickest to be 80mm, operates on the curved surface and carries out, particularly furnace bottom water cooling tube perforate, the furnace shell diameter reaches 15.80m, and the plan-position discrepancy in elevation reaches 360mm, use the utility model to carry out perforate, satisfied construction requirement.

Referring to Fig. 7, crossbeam is divided into two

section

11,12 that can slide up and down relatively, is convenient to head and slides up and down, and simultaneously the copper air feed short tube of apparatus body is changed lengthening with plastic flexible pipe, guarantees that frame can be free movable.Adjusting bolt 8 can be controlled cutting machine and be in level on curved surface, and the cutting torch place fascinates with curved surface during cutting, and 0 °-50 ° of the scopes of fascinating guarantee to cut and normally carry out.With scale guide rod short (than the short 100mm of existing scale guide rod), be convenient to the curved surface tap operation simultaneously, satisfactorily finish perforate task on the furnace shell.
