Necking device for aluminum alloy profile

Abstract

The invention discloses a necking device for an aluminum alloy profile. The necking device is used for gradually shaping the aluminum alloy profile through a gradual change type inward-necking outlineso as to avoid a jamming phenomenon. The necking device is characterized in that two main body frames are arranged on two sides of a guide frame respectively, the main body frames are L-shaped frames, the length of the main body frames is shorter than the length of fixed frames, multiple pairs of connecting lugs are arranged on the guide frame at equal intervals, the pair of connecting lugs are close to the two sides of the guide frame respectively, multiple supporting rollers are arranged on the guide frame, the two ends of each supporting roller are connected with one corresponding pair ofconnecting lugs respectively, the multiple pairs of fixed frames distributed at equal intervals are arranged on each main body frame, the fixed frames are L-shaped frames, two fixing lugs are arrangedat the joint between each main body frame and a connecting frame, a fixing shaft is arranged at the joint between each main body frame and the fixed frames, the two ends of each fixing shaft are connected with the two corresponding fixing lugs respectively, the fixing shafts sequentially penetrate through the multiple fixed frames, one end of the guide frame is arranged on one pair of fixed frames, and the other end of the guide frame extends upwards in an inclined mode.

Description

technical field [0001] The invention relates to an aluminum alloy profile closing device, which relates to a closing device for closing and shaping an aluminum alloy profile, and belongs to the field of plate processing. In particular, it relates to a mouthpiece which avoids jamming by gradually shaping the aluminum alloy profile through a gradual inward contour. Background technique [0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry. They have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industries. When manufacturing aluminum rails, especially because the overall thickness of the rails is thin, the C rails during processing are prone to deformation, and the thin plates on both sides of the C-shaped rails expand outwards, which affects normal use.

[0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry. They have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration and chemical industries. When manufacturing aluminum rails, especially because the overall thickness of the rails is thin, the C rails during processing are prone to deformation, and the thin plates on both sides of the C-shaped rails expand outwards, which affects normal use. However, the existing devices for rail aluminum shaping are in use At the same time, the expanded C-shaped track is closed and shaped by adjusting the pressure roller with a good gap distance. However, the C-shaped track with a larger flare is directly contacted with the large-spaced pressure roller during shaping. Excessive difference in the size of the track openings will cause jamming, which will affect the normal shaping process of the track

[0003] The notification number CN209439238U discloses a track-type aluminum material shaping device, which includes a mounting bracket on which an expanding wheel set and a contracting wheel set are installed, and the expanding wheel set and the contracting wheel set are on a straight line. The expansion wheel set and the contraction wheel set include two oppositely arranged pressure wheels connected by rotation of the roller shaft. A gland is provided between the pressure wheels and the mounting bracket. Both ends of the pressure wheels protrude from the The two ends of the gland are fixedly connected between the pressure roller and the gland. The shaping device directly expands and shapes the deformed profile through the expansion wheel set. The large difference in the deformation mouth will cause jamming, which will affect the production process of plastic surgery
