Abstract

The invention discloses an aluminum alloy U-shaped pipe forming mechanism. The aluminum alloy U-shaped pipe forming mechanism comprises a rack and is characterized in that a fixed mold is arranged onthe rack and comprises a semicircular mold plate and a rectangular mold plate which is in tangent connection with the semicircular mold plate to form a whole body; concave arc-shaped mold grooves areformed in two sides of the rectangular mold plate which is tangent to the semicircular mold plate along the circular arc periphery of the semicircular mold plate; a planet mold matched with the fixedmold is arranged along the circular arc periphery of the semicircular mold plate; the motion trail of the planet mold is the circular motion taking the center of the semicircular mold plate of the fixed mold as the center of the circle; and a pipe fixed mold is arranged on the rack and is matched with the rectangular mold plate of the fixed mold; and a mold cavity equivalent to the outer diameterof a bent pipe is formed outside a bent pipe body, so that basic requirements such as the roundness of a bended-arc segment are ensured, the whole forming process is stable and continuous, and the cracking of the pipe body caused by uneven stress is avoided.

Description

technical field [0001] The invention relates to an aluminum alloy tube forming technology, in particular to an aluminum alloy U-shaped tube forming mechanism. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts and round pipe products is increasing. However, the ring (arc) shape of the metal pipe cannot avoid the deformation of the arc section. For example, the patent publication number is CN107695686A, a U-shaped copper tube forming machine, including a base, a hydraulic cylinder is arranged on the base, a pressure rod is arranged under the hydraulic cylinder, a rotatable turntable is arranged under the pressure rod, and a uniform ring is arranged on the turntable. There are 5 sta...
