Abstract

The invention discloses double-ended tube expanding equipment for hardware tubes. The double-ended tube expanding equipment comprises a pressing mechanism for pressing the hardware tubes in an expanding process, and expanding mechanisms for expanding the end parts of the hardware tubes, wherein the two expanding mechanisms are separately arranged at the two sides of the pressing mechanism; the pressing mechanism comprises a pressing part used for pressing transversely arranged hardware tubes and a pressing drive device for controlling the pressing part to open and close; and each expanding mechanism comprises an expanding mould and an expanding drive device for driving the expanding mould to move in a direction towards or away from the pressing mechanism. According to the double-ended tubeexpanding equipment for hardware tubes disclosed by the invention, the two expanding mechanisms are separately arranged at the two sides of the pressing mechanism; in the expanding process, the hardware tubes are transversely arranged, so that the pressing mechanism can guarantee stability when the hardware tubes are placed; the two expanding mechanisms can simultaneously expand the hardware tubes from the two sides of each hardware tube, and time needed for double-ended expanding of the hardware tubes can be greatly shorted through two-end synchronous expanding, so that efficiency of a hardware tube double-ended expanding process is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a double-head tube expansion device for metal tubes. Background technique [0002] Electric struts for the automatic opening and closing of automobile tailgates have been widely used and have gradually developed into standard products. Hardware pipes such as "down pipe" parts in this product require equipment to be equipped with molds for double-ended expansion to meet the structure of the product. needed. [0003] At present, in a typical implementation of the double-ended expansion of metal pipes, the metal pipes to be processed are placed upright in the processing equipment, and the processing equipment expands one end of the metal pipes through the mold, and then manually rotates the metal pipes up and down. , The processing equipment expands the other end of the metal pipe through the mold. [0004] However, in this kind of bulging operation, because the two ...
