Abstract

The utility model relates to a circumferential adjusting mechanism of a burring machine used in a butt weld pipe, which comprises a connecting nest plate, and is characterized in that: the connecting nest plate is provided with a hanger, the hanger is connected with a left suspender and a right suspender through adjusting screws vertically arranged, and a toolbar shaft is connected on both the left suspender and the right suspender by a pin shaft. In the utility model, a user can move the left suspender and the right suspender up and down respectively by rotating the adjusting screws, so as to drive the toolbar shaft to sway left and right by a certain angle, the adjusted angle of swing is not limited by the breadth of the welded steel pipe opening, the maximum angle of swing of a scraper can be adjusted to +-8 degree-10 degree, so as to meet the requirements of rotary welding lines of the scraped steel pipe to the maximum. In addition, after adjusting the angle of swing of the scraper, the two adjusting screws are fastened, the toolbar shaft and the scraper can achieve accurate location without clearance, and the burr quality in the welding lines of the scraped steel pipe is more stable.

Description

The circumferential guiding mechanism of burr remover in the ERW

Technical field

The utility model belongs to the steel pipe's production technical field, particularly relates to the circumferential guiding mechanism of burr remover in a kind of ERW.

Background technology

In the high-frequency straight seam welded pipe production process,,, need to remove inside and outside burr in order to reach corresponding quality standard through burr and outer burr in the inside and outside both sides generation of steel pipe seam after the high-frequency welding.Remove the interior burr of steel pipe at present and generally adopt online interior burr remover.Owing to adjust and steel-plate shape, steel pipe seam produces the rotation of certain angle sometimes, and promptly steel pipe seam is a helical form, therefore on interior burr remover the circumferential adjusting device of cutter will be arranged, to satisfy the needs of steel pipe rotation weld seam.The circumferential adjustment structure of general at home interior burr remover is the center for the bar of operating with interior burr remover, and rotates in a circumferential direction by pendulum angle drive operator bar and the cutter of adjusting operator bar link.This kind circumferentially adjust structure be subjected to the restriction of steel pipe A/F circumferentially to adjust pivot angle in actual use can not be too big, be generally ± 5 °～7 °, therefore excessive when steel pipe rotation weld seam, when exceeding circumferential adjustment pivot angle, can not in time adjust normal scraping.Simultaneously since between link and the operator bar for movingly, adopt key or pin to connect again, the certain clearance amount is arranged, cause circumferential adjustment pivot angle instability, thereby cause interior burr scraping quality instability.

Summary of the invention

The utility model provides the circumferential guiding mechanism of burr remover in a kind of ERW for solving the technical problem that exists in the known technology, and it can have bigger adjustment pivot angle and adjust the back positioning stablity, improves the quality of scraping weld seam burr.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

The circumferential guiding mechanism of burr remover in a kind of ERW, comprise the connection cage plate, it is characterized in that: connect cage plate suspension bracket is installed, suspension bracket is connected with left suspension rod and right suspension rod by the adjustment screw rod of vertical installation, all is connected with cutter spindle by bearing pin on left suspension rod and the right suspension rod.

Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, the user rotates the adjustment screw rod, can make left and right suspension rod upper and lower respectively mobile, drive the certain angle of the left and right swing of cutter spindle, the pivot angle size of adjusting is not subjected to the restriction of welded still pipe A/F size, the maximum pendulum angle of scraper can transfer to ± and 8 °～10 °, can satisfy the needs of the steel pipe rotation weld seam of scraping to greatest extent.In addition, it is fastening to adjust screw rods with two after adjusting the end of scraper pivot angle, and cutter spindle and scraper can realize not having the accurate location of gap value, makes the quality of burr in the scraping steel pipe seam more stable.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is user mode figure of the present utility model;

Fig. 4 is the left view of Fig. 3.

Among the figure: 1, connect cage plate; 2, suspension bracket; 3, adjust screw rod; 4, left suspension rod; 5, right suspension rod; 6, bearing pin; 7, cutter spindle; 8, scraper; 100, steel pipe.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 to Fig. 4, the circumferential guiding mechanism of burr remover in a kind of ERW, comprise and connect cage plate 1, connect cage plate 1 suspension bracket 2 is installed, suspension bracket is connected with left suspension rod 4 and right suspension rod 5 by the adjustment screw rod 3 of vertical installation, all is connected with cutter spindle 7 by bearing pin 6 on left suspension rod 4 and the right suspension rod 5.

Adjustment screw rod 3 by be rotatably connected suspension bracket 2 and left suspension rod 4 right suspension rods 5, make left and right suspension rod upper and lower respectively mobile, make the relative position of two bearing pins on the suspension rod of the left and right sides change, and then drive cutter spindle 7 rotating certain angle, thereby reach scraper 8 is circumferentially rotated, follow the trail of the purpose of scraping steel pipe 100 rotation weld seam internal hair thorns.Because when adjustment cutter spindle 7 swings, left and right sides suspension rod all moves up and down, therefore the pivot angle of adjusting is not subjected to the restriction of welded still pipe 100 A/Fs, and the maximum pendulum angle of scraper 8 can reach ± 8 °～10 °, can satisfy the needs of scraping steel pipe rotation weld seam to greatest extent.In addition, it is fastening to adjust screw rods 3 with two after adjusting the end of scraper 8 pivot angles, and cutter spindle 7 and scraper 8 can realize not having the accurate location of gap value, makes the quality of burr in the scraping steel pipe seam more stable.

Claims

1. the circumferential guiding mechanism of burr remover in the ERW, comprise the connection cage plate, it is characterized in that: connect cage plate suspension bracket is installed, suspension bracket is connected with left suspension rod and right suspension rod by the adjustment screw rod of vertical installation, all is connected with cutter spindle by bearing pin on left suspension rod and the right suspension rod.
