Abstract

The utility model relates to an iron pipe bending tool. The tool comprises a handle, a large wheel and a small wheel, wherein, the large wheel and the small wheel are fixed on the same straight line on the same side of the front end of a handle; a long strip groove is formed at a part on the handle, which is corresponding to the small wheel; the small wheel is fixed on the handle through a small wheel shaft and a nut; one end of the small wheel shaft is clamped in the long strip hole; the large wheel and the handle are fixed on a base through a sleeve and a bolt; and an iron pipe fixing device corresponding to a clearance between the large wheel and the small wheel is arranged on the base. In the utility model, when the piece bolt and the piece nut are screwed up, the rotation of the large wheel and the handle cannot be influenced while the large wheel and the handle are fixed on the base by adopting a stepped shaft type design of the sleeve; the small wheel shaft adopts a similar design; after the small wheel is pushed along the long strip groove on the handle to clamp a bent iron pipe, a gasket is placed below the nut, and then the piece nut is screwed up to lock the position of the small wheel; and through the dimension design of the sleeve, the small wheel shaft and the base gasket, the centers of the bent iron pipe and the large and the small wheels can be positioned in the same plane.

Description

The bending iron piping tool

Technical field

The utility model relates to a kind of bending iron piping tool.

Background technology

At present the general front end that adopts a handle of domestic manufacturer is arranged on the bull wheel that keeps at a certain distance away on the same straight line and steamboat as bending iron piping tool (as shown in Figure 1).When pulling handle, institute's bending iron pipe reaches the purpose that bends iron pipe around the bull wheel bending of center fixation.When bending iron pipe, the center that is difficult to guarantee several wheels is in same plane, even the bolt on the handle may be deviate from from the bull wheel that is inserted.In addition, iron pipe bending position and bending radius are difficult to accurate control.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of can be in position accurately with the bending iron piping tool of accurate radius bending iron pipe.

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

A kind of bending iron piping tool, comprise handle, bull wheel and steamboat, bull wheel and steamboat are fixed on the same straight line of handle front end the same side, be provided with a rectangular groove with the steamboat corresponding position on the handle, steamboat is fixed on the handle by little wheel shaft and nut, little wheel shaft one end is stuck in the rectangular groove, and on base, base is provided with the corresponding iron pipe fixture in gap between and large and small the wheel by sleeve and bolting for bull wheel and handle.

Described sleeve is a step structure, and bull wheel, base and handle all are enclosed within different-diameter place on the sleeve.

Described iron pipe fixture comprises two parallel heel pins that are vertically installed on the base, is respectively equipped with the base pad between two heel pins and the base.

Described large and small the wheel is the wheel of being with deep-slotted chip breaker on its periphery, and large and small deep-slotted chip breaker width and the deep equality of taking turns.

Be provided with pad between nut on the described little wheel shaft and the rectangular groove, little wheel shaft is a step structure, and steamboat and handle all are enclosed within different-diameter place on the little wheel shaft.

The utility model is when tightening part bolt and part nut, and the multidiameter pattern design that sleeve adopts does not influence its rotation when making bull wheel and handle be fixed on the base.Little wheel shaft also adopts similar design.Promote pad to be put under the nut after steamboat chucking institute bends iron pipe along the rectangular groove on the handle, tighten the part nut then and lock little wheel location.By to sleeve, the size design of little wheel shaft and base pad, can make the center of the iron pipe center that bends and bull wheel and steamboat in same plane.Adopt the utility model can be in position accurately with accurate radius bending iron pipe.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Shown in Fig. 2-4, a kind of bending iron piping tool, comprise handle 9, bull wheel 5 and steamboat 11, bull wheel 5 and steamboat 11 are fixed on the same straight line of handle 9 front end the same sides, be provided with a rectangular groove 10 with steamboat 11 corresponding positions on the handle 9, steamboat 11 is fixed on the handle 9 by steamboat axle 13 and nut 4, steamboat axle 13 1 ends are stuck in the rectangular groove 10, bull wheel 5 and handle 9 are fixed on the base 6 by sleeve 2 and bolt 1, be provided with pad between nut on the bolt 1 and the base 6, base 6 is provided with one and the large and small corresponding iron pipe fixture 12 in gap of taking turns between 5,11.

Described sleeve 2 is a step structure, and bull wheel 11, base 6 and handle 9 all are enclosed within different-diameter place on the sleeve 2.

Described iron pipe fixture 12 comprises between two parallel heel pins, 8, two heel pins 8 that are vertically installed on the base 6 and the base 6 and is respectively equipped with base pad 7.

Describedly large and smallly take

turns

5,11 wheels that are on its periphery the band deep-slotted chip breaker, and large and small deep-slotted chip breaker width and the deep equality of taking turns on 5,11.

Be provided with pad 3 between nut 4 on the described steamboat axle 13 and the rectangular groove 10, steamboat axle 13 is a step structure, and steamboat 11 and handle 9 all are enclosed within different-diameter place on the steamboat axle 13.

The utility model is tighting a bolt 1 and during nut 4, and the multidiameter pattern design that sleeve 2 adopts does not influence its rotation when making bull wheel 5 and handle 9 be fixed on the base 6.Steamboat axle 13 also adopts similar design.Behind the 10 promotion steamboats of the rectangular groove on the handle 9, the 11 chucking institute iron pipes that bend 14, pad 3 is put into nut 4 times, tighten part nut 4 locking steamboats 11 positions then.By to sleeve 2, the size design of steamboat axle 13 and base pad 7, can make the center of the iron pipe that bends 14 centers and bull wheel 5 and steamboat 11 in same plane.Adopt the utility model can be in position accurately with accurate radius bending iron pipe 14.
