Abstract

The utility model provides an internal-burr removing device for a welded pipe, as shown in figure 1. The internal-burr removing device consists of an internal-burr removing tool, a connecting body, a traveling mechanism, a lower roller tension mechanism and an oil pipe joint. The internal-burr removing tool includes a tool bar, a truncated-cone-shape tool head, a tool head radial adjusting screw, a tool head fixing screw and a tool head direction adjusting nut. The traveling mechanism and the lower roller tension mechanism are installed on the connecting body and comprise two upper rollers, two lower rollers, a moving radial sliding block and an axial sliding block. A piston cylinder, a piston, a sealing ring, a compression spring and a piston fixing nut form a one-way cylinder. The oil pipe joint is installed at the rear end of the piston cylinder. The utility model has the advantages that the burr in the small-diameter welded steel pipe can be removed, the device is suitable for removing the burr in the welded steel pipe with a diameter from 28mm to 32mm, the structure is simple, the manufacturing cost is low, the operation is convenient, the maintenance is convenient and the like.

Description

Welded tube removes the internal hair thorn device

One, affiliated technical field:

The utility model relates to the burr remover in a kind of welded still pipe pipe, can in diameter is 28 millimeters to 32 millimeters welded still pipe, use.

Two, background technology:

Can burr be the high-leveled and difficult technology during welded tube is produced in welded tube was removed, and also was the important step in the welded tube production technology, was the critical process of ERW being carried out the processing of high accuracy welded tube, have material impact in broad range of applications more for the welded tube product.Therefore, burr remover in the development welded pipe pipe, to exploitation China welded pipe new product, it is significant to improve kind class and quality level, and its economic benefit is very remarkable.Welded still pipe is cheap, and is functional, and development prospect is widely arranged.

Three, summary of the invention:

The purpose of this utility model is to adopt the method for machinery and unit connection to process than the burr in the path welded still pipe by hydraulic system.

The purpose of this utility model is to solve like this: burr technology and device had carried out extensively in welded still pipe was removed, deep research, Shave tool to practicability is furtherd investigate, adopt cutting process to remove interior burr, analyzing the concrete operating mode of cutter, cutter profile full-size, the cutter material, on the bases such as cutting edge form, installing mechanism to cutter has carried out structural design, developed the internal hair that goes that is used in line traffic control and stung cutter, it comprises knife bar, the circular platform type cutter head, cutter head is radially adjusted screw, the cutter head hold-down screw, the cutter head direction is adjusted nut; By going the walking mechanism in the internal hair thorn device and the tension mechanism of bottom roller to guarantee that upper and lower roller is close to the inside pipe wall moving linearly; The tension mechanism of walking mechanism and bottom roller comprises two upper rollers on the connector, is installed in movably two bottom rollers, the one-way cylinder of radial slider; One-way cylinder is made up of piston cylinder, piston, sealing ring, compression spring, piston hold-down nut; Under the promotion of piston, the inclined-plane by axial slider moves two bottom rollers of radial slider, reaches the purpose that upper and lower roller is close to tube wall; Oil connection provides hydraulic oil and walking power by being connected with unit to burr remover in the pipe.

Four, beneficial effect of the present invention:

1, is applicable to than the burr in path welded still pipe processing, can processes diameter and be 28 millimeters to 32 millimeters welded still pipe.

2, owing to adopt the axis of rolling to make roller, make welded tube go internal hair thorn device fault to reduce, the life-span improves.

Five, description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 and Fig. 3 are the cutaway views of Fig. 1.

Six, the specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing and specific implementation process.

With reference to Fig. 1, Fig. 2 and Fig. 3, all parts of the utility model Fig. 1 are through machining, Fig. 1 comprises connector 6, be equipped with knife bar 1, circular platform type cutter head 2, cutter head at the front end of connector 6 and radially adjust screw 3, cutter head hold-down screw 4, cutter head direction and adjust the centre position that nut 5 guarantees cutter head and two upper rollers 25 of cutter hub, roller 25 is installed in above the cutter hub 6 by joint bolt 22 by roller shaft 23, spacer sleeve 24, catch 26.Be equipped with radial slider 7 in the connector 6 and below radial slider, be equipped with two rollers 21, wheel shaft 20, catch 19, fixed screw 18, also be equipped with axial slider 9.By thread connection piston cylinder 10, sealing ring 13, compression spring 11, check ring 12, piston hold-down nut 16, packing ring 15, piston 14 are arranged in the piston cylinder 10 at the cutter hub other end, piston 14 connects with axial slider moves axially axial slider.By thread connection oil connection 17, oil connection 17 provides hydraulic oil and walking power by the tension mechanism that is connected with unit to walking mechanism and bottom roller at the piston cylinder other end.
