Guide-adjustable bending machine for automobile square pipe fitting

Abstract

The invention discloses a guide-adjustable bending machine for an automobile square pipe fitting. The guide-adjustable bending machine comprises a rack, a rotating mechanism, a left mold mechanism, aright mold mechanism and a guide roller 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 mode; the left mold mechanism comprises a left mold clamping base, a transverse rod, a swing arm and a pipe pressing mechanism; the right mold mechanism comprises a right mold clamping base, a mold clamping sliding frame and a mold clamping air cylinder, and the rotating frame is provided with a mold clamping sliding rail perpendicular to the advancing direction of thepipe fitting; and the guide roller mechanism is positioned behind the left mold mechanism and the right mold mechanism. The guide-adjustable bending machine has the beneficial effects that the top surface of the pipe fitting can be automatically adjusted according to the size of the pipe fitting so as to be pressed, so that the pipe fitting cannot move in the bending process, and the pipe fittingcan be adjusted and guided to advance according to the size of the pipe fitting.

Description

technical field [0001] The invention relates to a bending machine, in particular to a bending machine for guiding adjustable automotive square tubes. Background technique [0002] At present, in the production field of auto parts, the bending process of pipe fittings needs to be carried out with matching bending machines. The main structure of the commonly used bending machines 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 surfa...

Problems solved by technology

However, this type of device has the following defects: it can only be bent for pipe fittings of a specific size. If pipe fittings of different sizes need to be bent, it is necessary to replace the equipment with matching sizes. If the existing mold base for clamping pipe fittings 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 make the top surface of the pipe unpressed, 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 condition. Affect the quality of bent pipe fittings
