Pipe bender with mandrel driving mechanism

Abstract

The invention discloses a tube bending machine provided with a concentric actuating mechanism, which comprises a machine table provided with a track, the concentric actuating mechanism, a tube pushing and delivering device and a tube bending device, wherein the concentric actuating mechanism is arranged upon the machine table and is provided with a base which is provided with a power source so as to drive the concentric actuating mechanism to move on the track of the machine table, the base is provided with a permanent seat for assisting a tube; the tube pushing and delivering device is arranged upon the machine table and assists the tube to pass through and is matched with the progress of bending the tube to be processed so as to drive the tube to be processed to move to the tube bending device; and the tube bending device can bend tubes. The concentric actuating mechanism can be used to match the function of freely adjusting the length of the tube to be processed on the machine table so as to shorten the length of the assisting tube and guarantee the quality of bending tubes to be processed.

Description

technical field [0001] The invention relates to a pipe bending machine with a core-through driving mechanism, in particular to a core-through driving device which can be freely adjusted and moved along with the length of the pipe to be processed, so as to change the length of the auxiliary pipe and improve the processing efficiency of the pipe A pipe bender with a core-through drive mechanism. Background technique [0002] The pipe bending machine is a common tool for pipe bending processing. As shown in Figure 1, the currently known pipe bending machine is equipped with a machine platform with a control device, and is equipped with a set of pipe fitting pushing devices a that can move laterally along the machine platform, and Use the pipe pushing device a to move the pipe to be processed, and then fix a base b at the end of the machine. The base b is provided with a fixing seat c to assist the fixing of the pipe d, so that the pipe pushing device a can pass through the auxi...

AI Technical Summary

Problems solved by technology

The base of the conventional pipe bending machine is completely fixed on the top of the machine (as shown in Figure 1), so in order to make the inner mold base of the auxiliary pipe fit with the pipe to be processed, the auxiliary pipe must be lengthened, that is, the pipe bender How long is the length of the auxiliary pipe fitting? The length of the auxiliary pipe fitting is about the same as the length of the pipe bending machine. When processing a shorter pipe fitting to be processed, the length of the auxiliary pipe fitting cannot be changed, causing the middle section of the auxiliary pipe fitting to sag, and the guiding effect is not good. When When the moving path of the pipe fitting pushing device is too long, the processing efficiency will be low, and the auxiliary pipe fittings that are too long will cause vibration due to the movement of the pipe fitting pushing device, which will affect the processing accuracy of the pipe bending machine and the quality of the pipe fittings
