Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a pipe bending machine used for manufacturing smart homes. Background Art

[0002] The existing smart home refers to a system that uses the residence as a platform and utilizes integrated wiring technology, network communication technology, security technology, automatic control technology, and audio and video technology to integrate facilities related to home life to build an efficient management system for residential facilities and family schedule affairs. Its use will enhance home safety, convenience, and comfort.

[0003] However, compared with traditional homes, the furniture structure of smart homes as hardware devices is more complicated and more difficult to process. For example, traditional pipe bending machines can no longer meet the bending needs of some special parts. With the increasing demand for special parts, researchers in related fields have also developed targeted pipe bending machines, such as the authorized patent with announcement number CN204194508U, which discloses a mobile right-angle pipe bending machine. When in use, "the bending of parts can be achieved by setting the upper and lower molds, and the forming groove is set to a right triangle, so that the parts can be bent into right angles at one time."

[0004] However, after the applicant conducted actual tests on the prior art, it was found that the technical solution of the prior art was theoretically fine, but after actual operation, although the tube body could present a right-angle state, the bend was flattened and the internal space of the tube body was deformed and could not be used.

[0005] After the applicant discovered the problems of the above-mentioned prior art, he further searched other prior arts. However, the pipe bending machines with classic structures, such as the authorized patents with announcement numbers CN214719639U and CN213223864U, are all aimed at pipe materials with longer lengths. The processing of short-segment pipe materials with special requirements is easily impossible due to the problem of insufficient limiting distance. Secondly, the bending structure cannot obtain effective heat dissipation after batch operation, and the rate of structural wear is also high. In summary, the prior art still has a lot of room for improvement. Therefore, the applicant will provide a pipe bending machine for smart home manufacturing to solve the problem.

[0035] Embodiment 1

[0036] For the bending process of the short tube 14, the short tube 14 is placed on the top of the two supporting die wheels 4, and then the electric push rod 5 is started, and then the output end of the electric push rod 5 pushes the upper module 3, the limit rod 7, and the bending die wheel 8 to move downward synchronously until the bending die wheel 8 contacts the short tube 14 and then gradually presses and bends the short tube 14 to a specified angle;
