Abstract

The utility model discloses a cutter bar device for removing inner burrs of small-caliber welded pipes in an online manner. The cutter bar device comprises a cutter bar body, two welded joint guiding wheels, lower rollers, a cutter seat and an annular scraper, wherein the two welded joint guiding wheels are arranged on the cutter bar body; the lower rollers are arranged at the upper end and the lower end of the cutter bar body and are positioned between the two welded joint guiding wheels; the cutter seat is connected with the tail end of the cutter bar body; the annular scraper is arranged on the cutter seat; the cutter seat is provided with a scraping depth adjusting screw; the lower rollers are connected with lower roller seats through lower semicircular roller shafts; and each lower roller seat is also connected with a corresponding scraping force adjusting screw. The cutter bar device can remove inner burrs, with the diameter of phi16*1.0mm, of the small-caliber welded pipes; welded joints are guided stably; and the production cost for the small-caliber welded pipes can be reduced.

Description

Small-bore welded tube removes inner burr cutter arbor device online

Technical field

The utility model belongs to ratio-frequency welded tube production technical field, is specifically related to a kind of small-bore welded tube and removes online inner burr device.

Background technology

In Welded Pipe Production Process, go inner burr device to have certain requirement to pipe diameter size.If internal diameter is less, while striking off inner burr, easily form and block, production work cannot be completed or steel pipe internal-surface is produced and weighed wounded.The high-quality that all parts of the country only have several factories can produce small dimension is at present removed inner burr steel pipe, and its minimum gauge also can only reach Φ 20 * 1.0mm.And for meeting market demand, produce Φ 16 * 1.0mm high-quality pipe, need to when meeting mechanical strength, to the existing inner burr device that goes, improve.

Summary of the invention

For the deficiencies in the prior art, what the utility model aimed to provide the small-bore welded tube of a kind of Φ of being specifically designed to 16x1.0mm removes inner burr cutter arbor device online.

For achieving the above object, the utility model adopts following technical scheme:

Small-bore welded tube removes inner burr cutter arbor device online, comprise knife bar body, be arranged on two weld seam directive wheels on knife bar body, be arranged on knife bar body lower end and the lower roll wheel between above-mentioned two weld seam directive wheels, the tool rest being connected with knife bar body tail end and be arranged on the annular scraper on above-mentioned tool rest, above-mentioned lower roll wheel is connected with lower roll wheel seat by semicircle lower roll wheel shaft, lower roll wheel seat also connects a scraping power set screw, is provided with scrape depth set screw on described tool rest; Described knife bar body diameter is of a size of 13x157.5mm, and its weld seam directive wheel outside dimension is 12.8mm.

The utlity model has following beneficial effect:

The small-bore welded tube of the utility model removes inner burr cutter arbor device online, and it can remove the small-bore burr in welded tube of Φ 16x1.0mm, and the production cost of small-bore welded tube is stablized and can be reduced to weld seam guiding.

Accompanying drawing explanation

Fig. 1 is the structural representation that the small-bore welded tube of the utility model removes inner burr cutter arbor device online.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model will be further described, understands the claimed technological thought of the utility model so that clearer.

Be illustrated in figure 1 the small-bore welded tube of the present embodiment and remove online inner burr cutter arbor device, comprise a knife bar body 1, be arranged on two weld seam directive wheels 2 on knife bar body 1, the lower roll wheel 3 that is arranged on knife bar body 1 lower end, the tool rest 7 being connected with knife bar body 1 tail end and be arranged on the annular scraper 8 on tool rest 7, this lower roll wheel 3 is arranged between two weld seam directive wheels 2 on knife bar body 1 and by a semicircle lower roll wheel shaft 4 and is fixedly connected on a lower roll wheel seat 5, also connects a scraping dynamics set screw 6 on this lower roll wheel seat 5; On tool rest 7, be also provided with a scrape depth set screw 9.Described knife bar body 1 outside dimension is 13x157.5mm, and its weld seam directive wheel 2 outside dimensions are 12.8mm.
