Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing auxiliary equipment, in particular to a bar close arrangement mechanism. Background Technique

[0002] After the metal bar stock is processed, it is usually necessary to cut the long bar stock into short bar stocks. For example, for aluminum alloy bar stocks: cut the long aluminum alloy bar (such as 21 meters) into short stocks. After the cut short stocks are transported to a predetermined station by a conveying mechanism, they are carried to other stations by a clamping and lifting mechanism. The cut short stocks are not closely arranged on the conveying mechanism, which affects the subsequent clamping and transfer process. The aluminum alloy bar stocks are relatively heavy and are not convenient for manual adjustment. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is that currently, the cut short stocks are not closely arranged on the conveying mechanism, which affects the subsequent clamping and transfer process. The aluminum alloy bar stocks are relatively heavy and are not convenient for manual adjustment.

[0004] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0005] A bar close arrangement mechanism includes two chain conveying mechanisms arranged in parallel. A synchronizing shaft for making them move synchronously is also arranged between the two chain conveying mechanisms. The synchronizing shaft is driven by an external driving motor through a chain and a gear. The chain conveying mechanism is installed on a frame. Transition plates are fixedly connected to the front and back of the frame near the middle thereof through bolts and nuts. The top of the transition plate is an inclined surface, and the included angle between the inclined surface and the horizontal plane is 15 degrees;

[0006] Inclined brackets are symmetrically arranged on the front and back of the frame on the left side of the transition plate in an inclined manner. The included angle between the top of the inclined bracket and the horizontal plane is 3 degrees.

[0007] Further, the inclined bracket includes a base fixedly connected to the outer surface of the frame through bolts and nuts. Shaft rods are fixedly connected to opposite sides of the base. A roller is rotatably connected to the outer surface of the shaft rod.

[0008] Further, several rollers are sequentially connected in series at intervals on the outer surface of the shaft rod and are rotatably connected thereto.

[0009] Further, a "J"-shaped touch rod is rotatably connected to the front of the frame near the left side of the inclined bracket. Limit adjusting seats are fixedly connected to the front of the frame at the left and bottom positions of the touch rod. Adjusting bolts are arranged on the inner surface of the limit adjusting seat and on the right side of the touch rod. A proximity switch is fixedly connected to the front of the frame at the position of the adjusting bolt of the touch rod;

[0010] On the outer sides of the opposite sides of the chain transmission mechanism and at the symmetric positions of the inclined brackets, alignment brackets are installed. An electric telescopic rod is arranged at the position of the inclined bracket near the top of the alignment bracket, and the ends of the electric telescopic rods close to each other are fixedly connected with an alignment plate;

[0011] The electric telescopic rods and proximity switches are electrically connected to an external controller;

[0012] A counterweight block is fixedly connected to the front of the trigger rod near the right side thereof.

[0013] Working principle and beneficial effects: By installing a pair of transition plates with inclined tops on the frame of the chain transmission mechanism, the included angle between the top and the horizontal plane is 15 degrees, and inclined brackets are installed at adjacent positions, the included angle between the top and the horizontal plane is 3 degrees. As the chain transmission mechanism drives the cut rod material to move, it is squeezed and conveyed to the inclined bracket under the action of the transition plate, and rolls downward to a position close to the left side of the inclined bracket under the action of its own gravity. And so on, the rod materials conveyed to the inclined bracket are finally closely abutted in sequence, which is convenient for the clamping and lifting mechanism to move to the next working station. Only when the included angle between the top of the inclined bracket and the horizontal plane is 3 degrees and the included angle between the top of the transition plate and the horizontal plane is 15 degrees can the chain transmission mechanism effectively push the rod material from the transition plate to the inclined bracket.

[0021] As Figures 1-3 shown,

[0022] A bar close-packed mechanism includes two chain transmission mechanisms 1 arranged in parallel. A synchronizing shaft 2 for making them move synchronously is also arranged between the two chain transmission mechanisms 1. The synchronizing shaft 2 is driven by an external driving motor through a chain and a gear. The chain transmission mechanism 1 is installed on a frame 3. Transition plates 4 are fixedly connected to the front and back of the frame 3 near the middle thereof by bolts and nuts. The top of the transition plate 4 is an inclined surface, and the angle between its inclined surface and the horizontal plane is fifteen degrees. Inclined brackets 5 are inclinedly arranged at symmetric positions on the left side of the transition plate 4 on the front and back of the frame 3. The angle between the top of the inclined bracket 5 and the horizontal plane is three degrees.

[0023] By installing a pair of transition plates 4 with inclined tops on the frame 3 of the chain transmission mechanism 1, the angle between the top and the horizontal plane is fifteen degrees, and inclined brackets 5 are installed at adjacent positions, the angle between the top and the horizontal plane is three degrees. As the chain transmission mechanism 1 drives the cut bar to move, under the action of the transition plate 4, it is squeezed and conveyed to the inclined bracket 5, and rolls downward under the action of its own gravity to a position close to the left side of the inclined bracket 5. By analogy, the bars conveyed to the inclined bracket 5 are finally closely abutted in sequence, which is convenient for the clamping and lifting mechanism to move to the next working station. The angle between the top of the inclined bracket 5 and the horizontal plane is three degrees, and the angle between the top of the transition plate 4 and the horizontal plane is fifteen degrees, so as to ensure that the chain transmission mechanism 1 can effectively push the bar from the transition plate 4 to the inclined bracket 5. The inclined bracket 5 includes a base 51 fixedly connected to the outer surface of the frame 3 by bolts and nuts. Shaft rods are fixedly connected to opposite sides of the base 51. A roller 52 is rotatably connected to the outer surface of the shaft rod. The angle between the roller 52 and the horizontal plane is three degrees. Several rollers 52 are sequentially connected in series at intervals on the outer surface of the shaft rod and are rotatably connected thereto, which is convenient for manually adjusting the ends of the bars to make them aligned.

[0024] There is also provided an automatic alignment device, and its specific mechanism is, as Figure 4As shown in the figure, a "J"-shaped trigger rod 6 is rotatably connected to the front of the frame 3 near the left side of the inclined bracket 5. Limit adjustment seats 7 are fixedly connected to the front of the frame 3 at the left and bottom positions of the trigger rod 6. Adjusting bolts are provided on the inner surface of the limit adjustment seat 7 and the right side of the trigger rod 6. A proximity switch 8 is fixedly connected to the front of the frame 3 at the position of the adjusting bolt of the trigger rod 6. Alignment brackets 9 are installed on the outer sides of the opposite sides of the chain conveyor mechanism 1 and at symmetrical positions of the inclined bracket 5. An electric telescopic rod 10 is provided at the position of the inclined bracket 5 near the top of the alignment bracket 9. Alignment plates 11 are fixedly connected to the mutually approaching ends of the electric telescopic rods 10. The electric telescopic rods 10 and the proximity switch 8 are electrically connected to an external controller. The bar stock located on the inclined bracket 5 rolls to its left side and presses the trigger rod 6 to rotate counterclockwise, then contacts the touch switch 8 and feeds back information to the controller. The controller starts to count down according to the preset time. After the countdown is completed, the electric telescopic rods 10 are controlled to work and extend, so that the alignment plates 11 move towards each other, squeezing the ends of the bar stock to complete alignment, thus liberating human labor. The adjusting bolts provided on the limit adjustment seat 7 limit the rotation angle of the trigger rod 6, playing a role in protecting the proximity switch 8. A counterweight 12 is fixedly connected to the front of the trigger rod 6 near its right side, so that after the clamping and lifting mechanism removes the bar stock located on the inclined bracket 5, the trigger rod 6 can automatically reset.
