Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing, in particular to a full-automatic aluminum alloy extrusion forming device. Background Technique

[0002] The aluminum alloy cold extrusion forming equipment is a processing method in which an aluminum alloy blank is placed in a cold extrusion die cavity, and at room temperature, a punch fixed on a press applies pressure to the blank, causing the metal blank to undergo plastic deformation to obtain parts.

[0003] The existing publicly disclosed patent CN210756356U discloses a full-automatic aluminum alloy plate extrusion device for furniture. The feeding mechanism is arranged to facilitate pushing the aluminum strip to be processed, transporting the aluminum strip to be processed to the extrusion area for extrusion. The advancing aluminum strip is extruded by the upper pressing roller and the lower pressing roller, and as the distance between each group of upper and lower pressing rollers decreases, the aluminum alloy plate is extruded and formed. The cutting machine is driven by the lifting mechanism to move down to cut the extruded aluminum strip. At the same time, the pressing mechanism presses and fixes both sides of the aluminum strip to ensure the stability of the cutting process. Automatic cutting treatment is carried out according to the length of the aluminum strip to be produced, which is convenient to control, reduces labor consumption, and improves work efficiency.

[0004] During the use of the above device, when multiple upper and lower rollers extrude the aluminum strip, while the thickness of the aluminum strip under pressure changes, its width will also extend. Since there is a lack of limitation on the extended width of the aluminum strip during the extrusion process of the aluminum strip, it is not only inconvenient to control the width of the aluminum strip during the extrusion process of the aluminum strip, but also unevenness will occur on both sides of the aluminum strip, and there are defects during the use process.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1: Please refer to Figure 1 、 Figure 3 , a fully automatic aluminum alloy extrusion forming device shown in the figure, includes a bracket 1, on which a plurality of pressure rollers 2 are rotatably installed, and further includes a width limiting structure 3 for limiting the width of the aluminum strip, the width limiting structure 3 is installed outside the pressure roller 2; an oil injection structure 4 for reducing the friction between the aluminum strip and the width limiting structure 3, the oil injection structure 4 is installed outside the width limiting structure 3; a pressing component 5 for connecting the width limiting structure 3 and the oil injection structure 4, the pressing component 5 is installed below the width limiting structure 3.

[0023] Please refer toFigure 2 The width-limiting structure 3 includes baffles 301 that are movably in contact with a plurality of pressure rollers 2. The number of baffles 301 is two groups and they are symmetrically distributed. Two bidirectional screws 302 are installed on the lower side of the baffle 301. The rotation of the bidirectional screw 302 can drive the baffle 301 to move.

[0024] Please refer to Figure 2 One end of one of the bidirectional screws 302 is fixedly connected to a motor through a coupling. Two symmetrically distributed connecting blocks 303 are fitted and installed on the outer side of the bidirectional screw 302, and the connecting blocks 303 are fixedly connected to the baffle 301. A driving roller 304 is rotatably installed at the right end of the baffle 301. The driving roller 304 facilitates the entry of the aluminum strip between the two baffles 301.

[0025] The working principle for facilitating the control of the processing width of the aluminum strip: The operator controls the operation of the motor. Under the action of the synchronous pulleys and synchronous belt, the motor drives the two bidirectional screws 302 to rotate synchronously. The rotation of the bidirectional screw 302 drives the two baffles 301 to approach or move away from each other through the connecting blocks 303. After adjusting the distance between the two baffles 301 according to requirements, the feeding mechanism conveys the aluminum strip. The aluminum strip is extruded by a plurality of pressure rollers 2, and its width gradually becomes larger. The two baffles 301 block the two side edges of the extruded aluminum strip, which can limit the width of the extruded aluminum strip. This not only makes the processing width of the aluminum strip easy to control, but also helps the edges of the processed aluminum strip to be neat.

[0026] Embodiment 2: Please refer to Figure 3 This embodiment further elaborates on Embodiment 1. The oil spraying structure 4 includes two symmetrically distributed rubber balloons 401, and the rubber balloons 401 are located under the baffle 301. The rubber balloons 401 have a resilient property. The rubber balloons 401 are fixedly connected to the baffle 301 through a fixing plate 6. One conduit 402 is installed on each side where the two rubber balloons 401 are close to each other, and one conduit 403 is installed on each side where the two rubber balloons 401 are far from each other.

[0027] Please refer to Figure 3 One-way valves 404 are fixedly installed between the conduit 402, the conduit 403 and the rubber balloon 401. A plurality of atomizing nozzles 405 are fixedly installed on each side where the two baffles 301 are close to each other. The atomizing nozzles 405 can atomize the lubricating oil, and the atomizing nozzles 405 are communicated with the conduit 403. An oil tank 406 is installed under the baffle 301, and the conduit 402 is communicated with the oil tank 406.

[0028] Please refer to Figure 4 The pressing assembly 5 includes a disc 501 fixedly sleeved on the lower end of the positioning shaft of the driving roller 304. A pressing rod 502 is fixedly embedded at the lower end of the disc 501. The pressing rod 502 is cylindrical.

[0029] Please refer toFigure 4 When pressing the circular part of the pressing rod 502 away from the disc 501, a ball 503 is movably embedded at the lower end of the pressing rod 502. The ball 503 can reduce the rotational resistance of the pressing rod 502, and the ball 503 is in rolling contact with the rubber balloon 401.

[0030] In this embodiment: during the process of the feeding mechanism conveying the aluminum strip, the aluminum strip will drive the transmission roller 304 to rotate. During the rotation of the transmission roller 304, the disc 501 and the pressing rod 502 are driven to rotate. During the rotation of the pressing rod 502, the rubber balloon 401 is extruded through the ball 503. After the rubber balloon 401 is extruded, under the action of the one-way valve 404, the quantitative lubricating oil in the rubber balloon 401 enters the second conduit 403. The quantitative lubricating oil in the second conduit 403 is sprayed out through the atomizing nozzle 405. The atomizing nozzle 405 sprays the lubricating oil on the side wall of the baffle 301, so that when the baffle 301 blocks the two side edges of the aluminum strip, the friction between the aluminum strip and the baffle 301 can be effectively reduced, and the service life of the baffle 301 can be prolonged.

[0031] Embodiment Three: Please refer to Figure 2 This embodiment further illustrates Embodiment One. The two bidirectional screws 302 are linked by a synchronous pulley and a synchronous belt.

[0032] In this embodiment: by adjusting the two baffles 301 through the two bidirectional screws 302, the rotation of the baffle 301 can be effectively avoided, thereby avoiding the contact between the baffle 301 and the pressing roller 2.
