A pipe bending hydraulic forming mold

Abstract

A hydraulic forming mold for bending pipes includes an auxiliary baffle fixedly connected to one side of the upper end face of a base plate. An arc-shaped groove is formed on the upper inner side of the auxiliary baffle. A hydraulic rotating device is connected to the upper part of the base plate. A bending assembly is also connected to the upper part of the base plate. A hydraulic pipe is connected to the lower part of the hydraulic rotating device, penetrating the base plate. A hydraulic pump is connected to the end of the hydraulic pipe away from the hydraulic rotating device. Fixed posts are fixedly connected to the four corners of the lower end face of the base plate. A pipe is inserted between the arc-shaped groove of the auxiliary baffle and the mold wheel. The advantage of this invention lies in the bending assembly. By placing the pipe between the arc-shaped groove of the auxiliary baffle and the mold wheel, the hydraulic rotating device is activated, driving a bending block to bend the pipe. The bending angle of the pipe is controlled by the rotation amplitude of the hydraulic rotating device, reducing the limitations of the mold's use.

[0002] With the continuous development of technology and the increasing precision of machine processing, the requirements for the precision of machined parts are also constantly improving. In order to reduce material loss and save costs, machining often adopts methods that do not remove material or remove little material, such as injection molding, stamping, bending, electrical discharge machining, and wire cutting. Among these, bending has made great progress from the initial bending of large sheet metal parts to the bending of precision parts, and its proportion in existing machining is increasing year by year.

[0003] However, existing bending dies still have the following drawbacks:

[0004] Most existing bending dies use fixed bending models, which can only bend pipes at fixed angles and cannot finely adjust and control the bending angle, resulting in significant limitations of existing dies.
