Numerically-controlled pipe bending machine

Abstract

The invention discloses a numerically-controlled pipe bending machine. The numerically-controlled pipe bending machine is provided with an excess material auxiliary pushing trolley, wherein the excess material auxiliary pushing trolley can push pipe fitting excess materials in a pipe fitting clamping device out, and thus a pipe fitting is fully utilized, and waste is avoided. The numerically-controlled pipe bending machine is further provided with a multifunctional pipe fitting forming die. Due to the fact that the pipe fitting forming die is arranged, punch forming of the pipe fitting can be achieved while pipe bending is achieved, and cutting of the pipe fitting can also be achieved. According to the numerically-controlled pipe bending machine, station switching can be achieved by adjusting the horizontal position of a movable box and the rotation angle of a machine head box, and leftward bending and rightward bending of an integrated pipe fitting can be achieved by controlling the rotating direction of a rotary arm of an elbow pipe; an anti-wrinkle plate of the numerically-controlled pipe bending machine is provided with a lubrication system, and the service life of the anti-wrinkle plate can be prolonged through the lubrication system. The numerically-controlled pipe bending machine has the advantages of being more reasonable in structure, more practical, more comprehensive in function, and capable of improving the utilization rate of materials.

Description

technical field [0001] The invention relates to a numerically controlled pipe bending machine, in particular to a high-speed multi-axis machine that can make full use of surplus materials, and can realize stamping, cutting and blanking by setting a pipe end forming mechanism and a cutting mechanism on the basis of pipe bending processing. Linkage intelligent pipe bending machine. Background technique [0002] Pipe bending technology is widely used in the production and manufacture of pipe bends in central air-conditioning, automobile industry, aerospace industry, shipbuilding and other industries. The quality of pipe bends will directly affect the structural rationality of products in these industries , safety, reliability, etc., while the feeding of the pipe fittings during the pipe bending process of the pipe bender is mainly controlled by the booster device. However, when the pipe bender is pushing the pipe fittings to perform the last bend pipe bending process, the fron...

Problems solved by technology

[0009] However, the pipe fitting pushing device of the above-mentioned patented pipe bending machine has a complex structure and is troublesome to manufacture and assemble.

Moreover, usually when the pipe bender performs pipe bending, in order to ensure the roundness of the workpiece, a mandrel will be inserted into the pipe, and the excess material pushing device of the above-mentioned patented pipe bender will be used. These devices will interfere with the mandrel. The stroke is not enough to completely push out the remaining material in the pipe clamping device. If the radius of the mandrel is reduced to adapt to these devices, the roundness of the processed pipe cannot be guaranteed, and the pipe is easy to be in the bend during the bending process. produce wrinkles

Therefore, the pipe fitting pushing device of the above-mentioned patent pipe bending machine still cannot realize the full utilization of the remaining material under the premise of ensuring the processing quality

[0010] In addition, the anti-wrinkle plate of the pipe bender in the above-mentioned patent does not reduce the friction between the surface of the anti-wrinkle plate and the bending pipe fittings, that is, it does not improve the wear problem of the anti-wrinkle plate. Therefore, further improvement is needed

[0011] In addition, the head of the pipe bending machine in the above patent needs to cooperate with the pipe end forming machine to realize various pipe end processing functions such as flaring, shrinking, and pier head, and cannot perform left and right bending joint processing, nor can it meet the needs of processing.
