Description

Technical Field

[0001] The invention belongs to the technical field of fin production and processing, and particularly relates to an aluminum material cutting and discharging device for fin production and a discharging method thereof. Background Art

[0002] Fins are key components used to enhance the heat transfer efficiency in heat exchangers. They increase the heat transfer rate by expanding the heat transfer area. Fins are made of a variety of materials, including metals, plastics, and composite materials. Metal fins such as aluminum, copper, and stainless steel are widely used because of their good thermal conductivity and mechanical strength. During the production process of fins, the original sheet needs to be punched first, and then the punched original sheet needs to be cut and separated to form multiple fins of the same size. The set number of fins are stacked on top of each other, and finally the U-shaped copper tube is inserted into the fin hole on the fin to connect.

[0003] The inventor found that when the existing fins are cut and separated after punching, two thinner columns are usually used to insert the columns into the punched holes of the fins to achieve the collection of the fins. Although this method is simple, each time after a group of fins is collected, it is necessary to stop the machine, replace the next group of columns, and then collect them again. This method leads to low overall production efficiency. Moreover, after the fins are collected, it is necessary to manually remove the columns and then insert the U-shaped copper tubes, which makes the overall process very troublesome and wastes manpower and material resources.

[0004] Therefore, the existing structure and defects are studied and improved, and an aluminum material cutting and discharging device and a discharging method for fin production are provided, in order to achieve a more practical purpose. Summary of the invention

[0016] A method for discharging an aluminum material cutting and discharging device for fin production, using the aluminum material cutting and discharging device for fin production, comprises the following steps:

[0017] S1 feeds the raw material sheet under the punching platen, and the punching platen moves downward to make the punching punch move toward the punching die, so that the raw material sheet is automatically punched. When the punching is completed, the waste material after the punching is automatically ejected and separated; the raw material sheet is punched in sequence in the above manner;

[0018] S2 The punched raw material plate enters the cutting box, and the cutting knife in the cutting box is controlled to cut the raw material plate into fins of the same size. The cut and separated fins automatically fall to the support plate in the collection mechanism below due to gravity; as the fins continue to fall, the first conveying bar is controlled to rotate so that the support plate with the fins gradually moves downward, so that more fins can be installed on the support plate, and the distance the fins fall remains unchanged;

[0019] S3: When the fins on the support plate are placed to a set amount, the first conveyor bar is controlled to rotate so that the next group of support plates moves to the bottom of the cutting box, and the fins are continuously collected and placed. This cycle is repeated without stopping the machine, which can effectively improve the overall production efficiency.

[0020] When the neatly stacked fins S4 move to the bottom, the base plate with the U-shaped copper tube installed below is controlled to move upward automatically, so that the U-shaped copper tube can be automatically inserted into the punched hole on the fin, thus realizing the automatic installation of the U-shaped copper tube and the fin;

[0021] S5 During the installation of the fins and the U-shaped copper tube, the U-shaped copper tube is placed in the placement groove in the rotating plate at the feeding placement end, and the U-shaped copper tube is clamped and fixed; when the fins are completely placed in the U-shaped copper tube, the base plate is controlled to automatically restore the initial position, and then the rotating plate with the fins is rotated downward, and at the same time, the rotating plate with the U-shaped copper tube at the feeding placement end is controlled to rotate downward, so that the U-shaped copper tubes will not collide with each other when the second conveyor bar rotates;

[0022] S6 then controls the second conveyor bar to rotate, so that the rotating plate at the feed placement end moves to the fin collection and installation end, and the rotating plate at the fin collection and installation end moves to the discharge end, and the rotating plate at the discharge end moves to the feed placement end; the rotating plate entering the fin collection and installation end first rotates the U-shaped copper tube up and down, and then controls the base plate to drive the U-shaped copper tube upward to be installed with the fins; and the rotating plate entering the discharge end is released from the fixation, and the U-shaped copper tube with fins automatically falls off, thereby realizing automatic separation after the fin installation is completed; through such a cyclic reciprocating design, both the automatic installation of the fins and the automatic discharge after the fins are installed are realized, and at the same time, there is no need to stop the machine during the whole process, which effectively improves the overall production efficiency.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] The design of the first conveying bar and the support plate can utilize the rotation of the first conveying bar to drive the support plate to circulate. Since the first conveying bar rotates synchronously in the opposite direction, it can drive the support plates on the two first conveying bars to move downward synchronously, so that the two support plates form a plate for supporting the fins after cutting, and the distance between adjacent support plates can be used for inserting the U-shaped copper tube. Such a design not only realizes the transportation of the fins, but also does not affect the installation of the U-shaped copper tube. After a certain number of fins are placed on the support plate, another set of support plates can be directly moved to the bottom of the fallen fins by rotating to catch the fins. Such a design does not require shutdown when switching, and can be seamlessly connected, thereby improving production efficiency.

[0025] The design of the second conveying bar, the rotating plate, the placement groove and the base plate can utilize the rotation of the second conveying bar to realize the conveying of the U-shaped copper tube. The U-shaped copper tube can be placed in the placement groove, fixed by the clamping plate, and transported to the bottom of the collecting mechanism by the rotation of the second conveying bar. The base plate can move up and down, so that when the U-shaped copper tube moves to the bottom of the collecting mechanism, the upward movement of the base plate can drive the U-shaped copper tube to move upward and automatically insert it into the neatly stacked fins, thereby realizing the automatic installation of the fins and the U-shaped copper tube; after the installation is completed, the U-shaped copper tube can be separated from the collecting mechanism by the downward movement of the base plate, and the automatic separation of the U-shaped copper tube is realized by the rotation of the second conveying bar, so that the next U-shaped copper tube moves to the bottom of the collecting mechanism again for continued installation. The reciprocating design can fully improve the overall efficiency. The rotatable design of the rotating plate can effectively prevent the mutual interference between adjacent U-shaped copper tubes during the movement of the base plate on which the U-shaped copper tube is placed through the rotation of the rotating plate, thereby ensuring the overall stability.

The reciprocating design can fully improve the overall efficiency. The rotatable design of the rotating plate 4 makes the base plate 41 on which the U-shaped copper tube 3 is placed effectively prevented from interfering with each other during the movement of the base plate 41, through the rotation of the rotating plate 4, thereby ensuring the overall stability.

When the punching is completed, the waste material after the punching is automatically ejected and separated; the raw material sheet is punched in sequence in the above manner;

[0067] S2 After punching, the raw material plate enters the cutting box 12, and the cutting knife in the cutting box 12 is controlled to cut the raw material plate into fins 6 of the same size. The cut and separated fins 6 automatically fall onto the support plate 22 in the lower collecting mechanism 2 due to gravity. Since the distance between the top support plate 22 and the cutting box 12 is very short, the fins 6 will not fall in an irregular shape during the falling process, and due to the cooperation of the first fixed plate 23, the support plate 22 and the first conveying bar 25, the fins 6 can fall onto the support plate 22 in a horizontal shape; as the fins 6 continue to fall, the first conveying bar 25 is controlled to rotate, so that the support plate 22 equipped with the fins 6 gradually moves downward, so that more fins 6 can be installed on the support plate 22, and the falling distance of the fins 6 remains unchanged;

[0068] S3: After the fins 6 on the support plate 22 are placed to a set amount, the first conveying bar 25 is controlled to rotate, so that the next group of support plates 22 moves to the bottom of the cutting box 12, and the fins 6 are continuously collected and placed, and the cycle is repeated without stopping, which can effectively improve the overall production efficiency;

[0069] S4 When the fins 6 on the support plate 22 move to the squeezing plate 26, as the first conveying bar 25 rotates, the squeezing plate 26 can stack the fins 6 on the support plate 22 more neatly, until the first conveying bar 25 squeezes and fixes the front and rear ends of the fins 6, and then as the first conveying bar 25 moves downward with the fins 6, the distance between the first fixing plates 23 can make the squeezing period of the left and right ends of the fins 6 more concentrated and aligned, and a vibration mechanism can also be set on the first fixing plate 23 to make the fins 6 stack more neatly by using the vibration of the vibration mechanism. When the neatly stacked fins 6 move to the bottom, the first hydraulic rod 42 is controlled to drive the base plate 41 equipped with the U-shaped copper tube 3 to move upward automatically, so that the U-shaped copper tube 3 can be automatically inserted into the fin hole 61 on the fin 6, thereby realizing the automatic installation of the U-shaped copper tube 3 and the fin 6; and because the support plates 22 are symmetrically distributed, the width of the support plates 22 can be set, and the up and down movement of the base plate 41 can be coordinated, so that when the support plates 22 are separated from the fins 6, they will not be restricted by the base plate 41, thereby ensuring the overall stability;

[0070] S5 During the installation of the fin 6 and the U-shaped copper tube 3, the U-shaped copper tube 3 is placed in the placement groove 411 in the rotating plate 4 at the feed placement end, and the second hydraulic rod 414 is controlled to drive the clamping plate 415 to clamp and fix the U-shaped copper tube 3 to achieve the fixation of the U-shaped copper tube 3; when the fin 6 is completely placed in the U-shaped copper tube 3, the first hydraulic rod 42 is controlled to drive the base plate 41 to automatically restore the initial position, and the third hydraulic rod 541 on one side of the rotating plate 4 is controlled to drive the prism rod 542 to clamp with the prism groove 442. As the prism rod 542 is clamped with the prism groove 442, the prism rod 542 pushes the adjusting rod 44 6 moves, and under the transmission of the connecting piece 444, the ejection teeth 441 are driven to automatically contract, and the fixed connection between the rotating shaft 44 and the second conveying bar 51 is released, and then the corresponding rotating motor 52 is started to control the rotating plate 4 to rotate 180 degrees, so that the rotating plate 4 equipped with the fins 6 rotates downward. Due to the existence of the check teeth 32, the fins 6 will not fall off. At the same time, the rotating motor 52 at the synchronous shaft 54 ​​at the feeding placement end is controlled to start, driving the rotating plate 4 equipped with the U-shaped copper tube 3 to rotate 180 degrees, so that the U-shaped copper tube 3 is downward, so that when the second conveying bar 51 rotates, the U-shaped copper tubes 3 will not collide with each other;

[0071] S6 then controls the second conveying bar 51 to rotate, so that the rotating plate 4 at the feeding placement end moves to the fin 6 collecting and installing end, and the rotating plate 4 at the fin 6 collecting and installing end moves to the discharging end, and the rotating plate 4 at the discharging end moves to the feeding placement end; the rotating plate 4 entering the fin 6 collecting and installing end first rotates the U-shaped copper tube 3 up and down, and then controls the base plate 41 to drive the U-shaped copper tube 3 upward to be installed with the fin 6; and the rotating plate 4 entering the discharging end, the second hydraulic rod 414 drives the clamping plate 415 to contract, contact the fixation between the U-shaped copper tube 3 and the placement groove 411, and the U-shaped copper tube 3 equipped with the fin 6 automatically falls off, thereby realizing the automatic separation after the fin 6 is installed;

[0072] Through such a cyclic reciprocating design, both the automatic installation of the fins 6 and the automatic discharge of the fins 6 after installation are achieved. At the same time, there is no need to stop the machine during the whole process, which effectively improves the overall production efficiency.
