Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy ingot production, and in particular to an automatic forming device for aluminum alloy ingots. Background Art

[0002] The conventional aluminum alloy ingot casting and forming device at least comprises a frame, a chain conveyor belt arranged on the frame for rotating and circulating motion, a plurality of molds with concave cavities installed on the conveyor belt, and an aluminum liquid diverter cylinder arranged above the front end of the frame. The specific structure can be found in CN117718448B. The forming process is as follows: the molten aluminum liquid is cast into the concave cavity of the mold through the diverter cylinder, and the aluminum liquid in the mold is cooled and solidified during the conveying process. When it is transported to the rear end of the frame, the mold with the opening facing upward is flipped, and the opening of the mold faces the lower side. The aluminum alloy ingot after cooling and forming falls off due to gravity and / or external force, and the aluminum alloy ingot is demolded. The aluminum alloy ingot after demolding will fall into the lifting conveyor belt to be transported to the stacker for stacking and packaging. Since there is a certain height difference between the demolding position of the aluminum alloy ingot and the lower lifting conveyor belt, the aluminum alloy ingot after demolding directly hits the lower lifting conveyor belt, which has a large impact force and causes great damage to the lifting conveyor belt, resulting in a shortened life.

[0027] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] See also Figure 1 The existing forming device includes a frame 1, a chain conveyor 2 and a diverter cylinder 3. The chain conveyor 2 is arranged on the frame 1 in a rotatable and cyclical manner, and a plurality of molds 21 with concave cavities are also installed on the conveyor. The diverter cylinder 3 is arranged above the front end of the frame 1 to inject molten aluminum alloy liquid into the concave cavity of the mold 21. The aluminum alloy liquid in the mold 21 is cooled and solidified during the conveying process. A cooling device can also be added to accelerate the cooling, and the aluminum alloy liquid falls off at the rotating part of the tail end of the chain conveyor 2 and falls into the lifting conveyor 4 below, and is transported by the lifting conveyor 4 to the palletizer for stacking and packaging.

[0029] This application has improved the existing forming device, thereby developing an automatic forming device for aluminum alloy ingots. Figure 2-5 The tail end of the frame 1 is also provided with a slide plate 5, and the slide plate 5 is located outside the rotation position of the chain conveyor 2 and a gap is left between the slide plate 5 and the chain conveyor 2 for the aluminum alloy ingot to pass through. The slide plate 5 is used to receive the aluminum alloy ingot that falls off from the rotation position of the chain conveyor 2 and change the falling path of the aluminum alloy ingot. Specifically, it guides the aluminum alloy ingot to slide down or roll to the damping mechanism 7 set at the lowest end of the slide plate 5, and then falls into the lower lifting conveyor 4, with the help of the damping mechanism 7 to offset its falling impact, and finally falls on the lower lifting conveyor 4, avoiding the aluminum alloy ingot from directly hitting the lower lifting conveyor 4 after demoulding, reducing the damage to the lifting conveyor 4, and increasing the service life of the lifting conveyor 4.

[0030] As a further improvement to the above scheme, please refer to Figure 2-6 , the slide 5 is provided with at least two parallel connecting rods 51 on the side away from the chain conveyor 2, and the two ends of the connecting rod 51 are respectively connected to the frame 1. Since the rear end of the frame 1 is usually provided with an adjustment mechanism for adjusting the distance between the driving shaft and the driven shaft of the chain conveyor 2, the turning point of the right end of the chain conveyor 2 may change left and right; in addition, after replacing the mold 21 of different specifications, the distance between the slide 5 and the chain conveyor 2 may also need to be adjusted; therefore, the connection mode of the connecting rod 51 and the frame 1 is preferably detachable, so as to facilitate the corresponding change of the setting position of the slide 5 with the tension adjustment of the chain conveyor 2.

[0031] In order to further facilitate the adjustment of the setting position of the slide 5, the present application has made further improvements: the frame 1 is provided with a bracket 6, and the top of the bracket 6 is provided with a plurality of limit grooves 61 extending along the length direction of the frame 1, and the limit grooves 61 are used to be plugged with the ends of the connecting rods 51. For an embodiment, please refer to Figure 3, the limiting groove 61 is a U-shaped groove, and the opening of the U-shaped groove faces upward for the end of the connecting rod 51 to be inserted. In another embodiment, the limiting groove 61 is a hole groove, and the extending direction of the hole groove faces the side of the slide 5; both ends of the connecting rod 51 are coaxially provided with telescopic rods, and a compression spring is provided between the telescopic rod and the connecting rod 51, and the telescopic rod is used to be plugged into the hole groove.

[0032] As a further improvement to the above scheme, please refer to Figure 4-7 The damping mechanism 7 includes a fixed plate 71, a damping plate 72 and a damping spring 73. One end of the fixed plate 71 is fixedly connected to the lowest end of the slide 5, preferably by welding or directly forming the fixed plate 71 and the slide 5 by sheet metal; the damping plate 72 is provided on the side of the fixed plate 71 facing the chain transmission belt, and the damping plate 72 is hinged to one end of the fixed plate 71 near the slide 5; a damping spring 73 is also provided between the damping plate 72 and the fixed plate 71, so that the lowest end of the damping plate 72 is tilted toward the side of the chain conveyor 2 under the support of the damping spring 73 and the fixed plate 71, so that a herringbone structure is formed between the damping plate 72 and the fixed plate 71. It should be noted that when the damping mechanism 7 is set, when the damping spring 73 is in the natural state, the distance between the lowest end of the damping plate 72 and the chain conveyor 2 is preferably smaller than the outer contour of the aluminum alloy ingot, that is, the damping plate 72 closes the falling channel of the aluminum alloy ingot to ensure that the aluminum alloy ingot will inevitably hit the damping plate 72 during the falling process. When the detached aluminum alloy ingot slides down or rolls down the slide 5 to abut against the damping plate 72, the damping spring 73 is compressed to offset its falling impact. At the same time, the damping plate 72 deflects toward the fixed plate 71, thereby opening a channel for the aluminum alloy ingot to continue falling. After the aluminum alloy ingot is separated from the damping plate 72, the damping plate 72 is reset under the elastic force of the damping spring 73 and then re-closes the falling channel to receive the next aluminum alloy ingot.

[0033] Specifically, the damping spring 73 may be a torsion spring or a compression spring. In one embodiment, when the damping spring 73 is a torsion spring, please refer to Figure 7 The damping plate 72 is hinged to the fixed plate 71 through a rotating shaft, the torsion spring is sleeved on the outer circumference of the rotating shaft, and the two legs of the torsion spring are respectively in contact with the damping plate 72 and the fixed plate 71. When the damping spring 73 is a compression spring, the two ends of the compression spring are respectively in contact with the damping plate 72 and the fixed plate 71. Preferably, in order to position the compression spring, guide rods can be respectively provided on the opposite side of the damping plate 72 and the fixed plate 71, and the two ends of the compression spring are respectively sleeved on the outer circumference of the corresponding guide rods.

[0034] As a further improvement to the above scheme, in some implementation schemes, it is necessary to set a knocking mechanism at the tail end of the chain conveyor 2 to assist the aluminum alloy ingot to be demolded smoothly, such as the knocking structure disclosed in the utility model patent CN205996131U. Therefore, a window is also opened in the middle of the slide 5 to facilitate the knocking hammer to pass through the window and knock on the aluminum alloy ingot to be demolded.

[0035] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
