A full-size bending device for square pipe fittings

Abstract

The invention discloses a full-size bending device for a square pipe fitting. The full-size bending device comprises a rack, a rotating mechanism, a left mold mechanism and a right mold mechanism, wherein the rotating mechanism comprises a rotating frame, a rotating motor, a rotating shaft, a rotating chain and a rotating gear arranged on the rotating shaft in a sleeving manner; the left mold mechanism comprises a left mold clamping seat, a cross rod, a swinging arm and a pipe pressing mechanism; the right mold mechanism comprises a right mold clamping seat, a mold clamping sliding frame and amold clamping air cylinder; and the rotating frame is provided with a mold clamping sliding rail perpendicular to the advancing direction of the pipe fitting. The full-size bending device has the beneficial effects that the top face of the pipe fitting can be automatically adjusted to be pressed according to the size of the pipe fitting, so that the pipe fitting cannot move in the bending process.

Description

technical field [0001] The invention relates to a bending device, especially a full-scale bending device for square pipes. Background technique [0002] At present, in the field of auto parts production, the bending process of pipe fittings needs to be carried out with matching bending machines. The main structure of the commonly used bending machine is to use two clamping dies to bend the pipe fittings Advance clamping, and then rotate with one of the clamping molds as the center of rotation, so as to complete the bending of the pipe. For example, the prior art CN201711281173.5 discloses a pipe bending device in a pipe bending machine. The main shaft of the belt wheel module is arranged on the pipe bending machine frame, and the main shaft is driven by a driving device. One end is fixed on the main shaft through the connecting sleeve, the other end of the elbow arm is the swing end, one end of the outer protective plate is set on the outer surface of the elbow arm, the oth...

Problems solved by technology

However, this type of device has the following disadvantages: it can only be bent for pipes of a specific size. If pipes of different sizes need to be bent, it is necessary to replace the equipment with matching sizes. If the existing mold base for holding pipes is modified, only The bottom surface of the bearing pipe and the two sides of the clamping pipe can be used for pipes of different sizes. However, this generalization method does not prevent the top surface of the pipe from being pressed, especially for long pipes. Under the circumstances, the pipe fittings located outside the working range of the bending equipment will also sway when the equipment is in working state. Affects the quality of bent pipe fittings
