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 [0001] The invention relates to a hardware machine, more precisely, a manual copper pipe bending device. Background technique [0002] In the refrigeration system of the refrigerator, the throttle valve is an important part, and the fluid flow is controlled by changing the throttle section or throttle length. The connecting elbows of the throttle valve are mostly copper elbows, which require manual bending and welding during the manufacturing process. The existing method is to use a steel pipe for bending, and it is difficult to keep the curvature of the copper pipe consistent. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a manual copper pipe bending device. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A manual copper pipe bending device, the manual copper pipe bending device includes a blo...
