Pipe-bending machine

Abstract

The invention relates to a pipe-bending machine. A push-to-convey device used for conveying a pipe is arranged on a machine frame; a pair of pipe-bending shafts are arranged on the left side of the push-to-convey device; a pipe-bending wheel which can rotate around each pipe-bending shaft is respectively arranged on the pipe-bending shaft; an arc groove matched with the pipe in diameter is formed in the peripheral surface of each pipe-bending wheel; a limit base is fixedly arranged on the right side of each pipe-bending shaft; two semicircular positioning grooves are formed in the front and back of the left side of each limit base and is used for respectively limiting the pair of pipe-bending shafts; a round disc I suitable for eccentric rotation is arranged below the pipe-bending shafts; when the round disc I eccentrically rotates, one of the pair of pipe-bending shafts serves as an axial center, and one pipe-bending wheel rotates around the other pipe-bending wheel, so that the pipe between the pair of pipe-bending wheels is bent.

Description

technical field [0001] The invention relates to a pipe bender, especially a pipe bender with a synchronous rotation on the working surface, which is used for bending and forming heat dissipation pipes for refrigerators, freezers, air conditioners and other electrical appliances, especially for producing more elbows and shorter overall lengths. Long or soft heat pipes. Background technique [0002] The structure of the existing pipe bending machine is: a pushing device for conveying pipe fittings is provided on a platform, and the pipe fittings are pushed to the pipe bending device on the platform along with the rail by using the pushing device. Bending into a serpentine tube of required size, however, during the bending process, manual assistance is required between the tube body and the platform, that is, during the bending process of the tube, the head of the tube needs to be manually operated to follow the bending direction Rotate, otherwise the bending cannot be complet...
