Abstract
The invention discloses a manual-operation copper pipe bending device. The manual-operation copper pipe bending device comprises a block-shaped bending body. A cambered forming arc groove is formed in the top of the bending body. A straight shifting straight groove is formed in the bottom of the bending body. A rotation through hole is formed in the center of the bending body. The two sides of the shifting straight groove are respectively provided with a positioning through hole. According to the manual-operation copper pipe bending device, the forming arc groove is used, a user can place a bar-shaped copper pipe into the forming arc groove and directly shifts a shifting rod in the shifting straight groove so that the bending body can rotate around the rotation through hole until the shifting rod moves to the position of the positioning through holes, and the operation is simple and convenient. The manual-operation copper pipe bending device is simple in structure, convenient to operate, accurate in positioning and high in practicability.
Description
Technical field
The present invention relates to a kind of hardware machinery, or rather, is a kind of manual copper pipe apparatus for bending.
Background technology
In refrigerator refrigeration system, choke valve is a kind of important part, by changing throttling cross section or chock length to control fluid flow.The bridge piece of choke valve mostly is copper bend pipe, in manufacture process, need to manually carry out bending and welding.Existing method is to utilize a steel pipe to bend, and the camber of copper pipe is difficult to be consistent.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of manual copper pipe apparatus for bending is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of manual copper pipe apparatus for bending, the bending main body that described manual copper pipe apparatus for bending comprises a square shape, the top of described bending main body is provided with the shaping arc groove of an arc, the bottom of described bending main body is provided with the straight trough of stirring of type always, the central authorities of described bending main body are provided with a rotation through hole, and the described both sides of stirring straight trough are respectively equipped with a positioning through hole.
As preferred embodiment of the present invention, the degree of depth of described shaping arc groove be described bending main body thickness 1/2nd.
Manual copper pipe apparatus for bending utilization shaping arc groove of the present invention, user can put into the copper pipe of bar shaped in this shaping arc groove in advance, and directly plate is moving stirs the driving lever in straight trough, bending main body is rotated around rotation through hole, only to driving lever, move on the position at positioning through hole place, simple and convenient.This manual copper pipe apparatus for bending is simple in structure, easy to operate, and accurate positioning is practical.

The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
As shown in Figure 1 to Figure 3, the bending main body 2 that manual copper pipe apparatus for bending 1 of the present invention comprises a square shape, the top of this bending main body 2 is provided with the shaping arc groove 3 of an arc, what the bottom of this bending main body 2 was provided with type always stirs straight trough 4, the central authorities of this bending main body 2 are provided with a rotation through hole 5, and these both sides of stirring straight trough 4 are respectively equipped with a positioning through hole 6.
The degree of depth of this shaping arc groove 3 be this bending main body 2 thickness 1/2nd.
Be not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
