Abstract

The utility model discloses a manual roller pipe bender which belongs to a manual tool which can not require preprocess in any form and dynamic energy. The manual roller pipe bender can be directly used for bending cylinder materials and circular pipes of copper, steel, stainless steel, aluminum and other plastic deformation bar materials. The range of the bended diameter is form phi 4 to phi 25 mm, and the range of the bended semidiameter is from 10 to 100 mm. The bended angle which is shaped is unequal, and is between 0 DEG and 180 DEG according to requirements. The bended angle can be bended into a Z shape and various compound bended angles in arbitrary shapes in space. The bender is the supplement of a large-sized hydraulic pipe bender, and is widely applied to the manufacture, the installation and the maintenance of many aspects of a machine tool, a car, a tractor, a refrigerator, etc. The manual roller pipe bender is matched with a pipe cutter, a pipe increaser and a pipe reamer to form the combined tool of a complete manual pipe fitting manufactured product. The utility model mode has the advantages of easy use, simplicity and reliability.

Description

Manual roller pipe bender

The utility model is a kind of manual a kind of new device of using with the copper pipe, aluminum pipe and the steel pipe that bend shaping φ 3～φ 18.

Past generally bends various pipe fittings, must carry out heating anneal to pipe fitting with the method for oxygen welding earlier, bends shaping with hand then, or sand is gone up in the pipe fitting filling to bend, in order to avoid caliber is curved flat.So promptly waste energy, lose time again.

The purpose of this utility model is to provide a kind of not only without heating but also not needing to irritate sand, does not also produce the swan neck system of relative friction.It can bend the tubing of various diameters and the circular arc of various radiuses easily and effectively.Shown in figure two, figure three.

The purpose of this utility model is achieved in that this device has two handgrips.A fast pulley (2) is housed on the handgrip (1).It is to design by caliber that bends and arc radius.Being equipped with one on the handgrip (4) can rotate around self axis, simultaneously can be around the axial line revolution of fast pulley (2) by the drive of (6).By the R groove in the middle of two wheels institute's bend pipe spare is curved required form like this.In the process of bending, an end of pipe fitting " not " is on handgrip (1), and the other end is a free end.

The utility model structure is simple especially, simultaneously owing to be to adopt the method for rolling in the bend pipe process, so the Guan Bubian that bends, do not wrinkle, no marking.And can be easy to realize bending the pipe fitting of various different angles again along with different use occasions.Shown in figure four.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.As " figure one ".Below in conjunction with details and the working condition of figure one detailed description according to the concrete device that the utility model proposed.

This device comprises an integral cast handle (1), and a fast pulley (2) is housed on the integral cast handle.It is connected with little axle (5) same handgrip (4) through brace (6).Be in the position of tubulature material in this accompanying drawing.Scroll wheel (3) links to each other with little axle (5) same handgrip (4).Scroll wheel (3) can be around the axial line rotation of little axle (5) simultaneously.Along the rotation handgrip of the direction shown in the arrow (7) (4) time, scroll wheel (3) rotation on the one hand is simultaneously by the axis revolution of brace (6) around fast pulley (2).Thereby reach the purpose that bends pipe fitting.

Claims

1, hand is a kind of hand device that bends shaping φ 3～φ 18 pipe fittings with the roller pipe bender.This device has two handgrips (1), (4) and two wheels (2), (3).It is characterized in that fast pulley (2) is fixed on the handgrip (1), scroll wheel (3) is connected on the handgrip (4) with little axle (5).

2, device according to claim 1 is characterized in that scroll wheel (3) can be around the axial line revolution of fast pulley (2).Be can roll mutually in wheel (2), (3).

3, according to claim 1,2 described devices, it is 105 ° or 110 ° that the direction that it is characterized in that the axis direction of fast pulley (2) and handgrip (1) has an angle.
