Description

Technical Field

[0001] The invention relates to the technical field of tube bending and forming, in particular to a multi-mode high-precision tube continuous bending and forming device and a forming process. Background Art

[0002] Bending is the most common processing method in the history of metal pipe processing. Bending is to apply a certain amount of force on the pipe to make it produce a certain bending angle and radius, and bending metal pipes requires the use of pipe bending machines. The types of pipe bending machines include CNC pipe bending machines, hydraulic pipe bending machines and many other types.

[0003] According to the search, Chinese patent literature, announcement number: CN109127804B, discloses a bending and forming device for metal pipes and its forming method. A suitable forming mold is designed according to the cross section of the pipe. The forming mold is inserted into the hollow pipe except for the upper steel plate. The forming mold is driven to move by the rolling of the forming roller. During the forming process, the upper steel plate of the forming mold can transfer the contact force to the part in contact with the pipe; the bottom plane of the forming mold and the middle of the three-sided support rail work together to bend the inner wall of the pipe. The inner support of the forming mold and the three-sided support rail can prevent the side of the pipe from being concave or convex. The upper part of the inner support of the forming mold can be installed with a screw clamping block to fix the end of the pipe, and the installation of a longitudinal telescopic plate can provide support for the forming of the outer wall of the pipe; during the bending process of the metal pipe, the inner wall is intact, the side wall and the outer wall are partially stretched, and the wrinkles are reduced or even disappear.

[0004] However, the above-mentioned tube forming device still has the following defects: first, the bending direction of the tube cannot be adjusted, so that the tube can only be bent once or multiple times in the same direction during one processing, and cannot be formed at one time; second, it cannot bend multiple tubes at one time, and the processing efficiency is low; finally, there are many operation steps in the process of bending the tube. Therefore, we need to make improvements on this. Summary of the invention

A multi-mode high-precision tube continuous bending forming process, using a multi-mode high-precision tube continuous bending forming device according to any one of claims 1 to 9, characterized in that: Proceed as follows: S1, inserting the metal tube to be bent into the end surface through hole of the circular shell (51), manually operating the clamping assembly (5) to fix the metal tube, and ensuring that the metal tube is in the tube groove of the clamping tube (54); S2, the inclined plate (86) is driven to rise by starting the first cylinder (89), and the inclined plate (86) drives the triangular plate (87), and finally the pressing die (88) and the bending die (82) are clamped on the outer surface of the metal tube; S3, starting the third cylinder (96) to drive the support (92) to move, and the support (92) drives the auxiliary mold (94) to fit the metal pipe; S4, starting the hydraulic cylinder (11) to drive the gear rod (12) to move, the gear rod (12) drives the second gear (83), the second gear (83) drives the main shaft (81) to rotate, and the main shaft (81) drives the bending die (82) and the pressing die (88) to rotate to bend the metal tube; S5. During the bending process, the second cylinder (95) is started to drive the slide plate (93) to move, and the slide plate (93) drives the auxiliary mold (94) to move, thereby ensuring that the metal tube does not generate wrinkles. At the same time, the second motor (14) is started to drive the screw rod (13) to rotate, thereby driving the metal tube to move in the direction of the bending assembly (8).
