Abstract

The utility model discloses a pipe bender which consists of a handle (7'), a rocker (8) and a track (9). The rocker arm (8) is fixedly connected with the handle (7'), a shaft pin (4) is sleeved in the middle, the roller (2) is sleeved on the shaft pin (4), the two sides of the roller are respectively clamped with the pressure springs (6), when in use, the roller can be adjusted left and right by the elasticity of the pressure springs to accurately press the bent pipe on the track, and then a force is applied on the handle to wind the bent pipe on the S₁The pipe is bent by rotation. When the pipe bender is used for working, the friction of the pipe can be reduced, the quality of a finished product is improved, and the pipe bender is flexible to operate, convenient to carry and labor-saving.

Description

Pipe bender

The utility model relates to a kind of new-type pipe bender.

In usual mechanical action, usually run into and to bend pipe fitting.In order to reach this purpose, adopt a kind of pipe bender on the market, it is provided with two tracks, and pipe is placed in the track, and another track slides along pipe under handle drives, thereby pipe is bent.Though this method can reach the purpose that pipe fitting is bent, because of it is the friction slip power realization purpose of tube and track, frictional force can make tube surface coarse, thereby influences end product quality.

The utility model purpose provides and does not a kind ofly influence end product quality, and laborsaving, easy to use pipe bender.

In order to achieve the above object, this pipe bender has adopted by roller, handle, has broadcast the structure that arm, track, hook plate are formed.Roller is located at handle and rocking arm junction, and fixes with pivot pin, and roller can rotate around pivot pin, and under handle drove, roller bent pipe along the track direction.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the front view of the utility model pipe bender.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the rearview of the utility model pipe bender.

This pipe bender is made up of roller 2, handle 7, rocking arm 8, track 9, hook plate 10.Broadcast arm 8 and handle 7 ' weld together by a U-shaped pipe 12.In the U-shaped pipe 12, overlap a pivot pin 4, roller 2 is enclosed within also can be around S on the pivot pin 4 ₂Rotation.U-shaped pipe both sides tighten pivot pin with outer snap ring 5 respectively.Blocked stage clip 6 respectively between roller both sides and U-shaped pipe 12 inwalls.The inner face width of roller during use, is put into the elasticity that track 9 relies on stage clips to pipe with suitable by the pressure pipe diameter, can the left and right adjusting roller, and it accurately is pressed in pipe in the track.Hook plate 10 is fixing with rocking arm 8 usefulness nuts 1 and pad 3, and rocking arm is a starting point with 13 positions, track hole, with S ₁Be the center, rotate around it, till forwarding two handles bottoms to and touching.

Certainly, handle 7 ' can adopt alternate manner with being connected of rocking arm 8, as long as both can be fixed together.The length of handle can be selected as required, and handle is outer can to overlap sleeve 11 on the other hand.

This utility model has been made finished product, uses very conveniently through me, and it is simple in structure, and flexible operation is easy to carry, more laborsaving.

Claims

1, a kind of pipe bender is made up of handle, rocking arm, track, hook plate.For flexibly connecting, rocking arm is with handle, hook plate and between rocking arm has fixedlys connected between hook plate and the rocking arm.It is characterized in that: cover one pivot pin (4) between rocking arm (8) and the handle (7 '), roller (2) is enclosed within pivot pin (4) and goes up and can rotate around pivot pin.

2, pipe bender according to claim 1 is characterized in that: described roller both sides are provided with elastomeric material (6) respectively, and pivot pin (4) two ends are fixing with snap ring (5).
