Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment, and in particular relates to an automated production line for a micro iron core storage tank. Background Technology

[0002] The iron core is the main magnetic circuit component of a transformer. It is typically made of stacked hot-rolled or cold-rolled silicon steel sheets with a high silicon content and an insulating varnish coating. The iron core and the coil wound around it form a complete electromagnetic induction system. The current method of winding the iron core involves manually placing it on the loading station, then using a pusher cylinder to move it to the winding station for winding. This method requires a lot of manual labor and has a low production speed. Therefore, people are looking for a better production method.

[0003] In the manufacturing of grooved components, feeding, pressing, and shaping are required. In existing production methods, during feeding, the raw material is often cut into sheet blanks and then conveyed to the next station for forming via rollers. However, this method lacks precision and cannot accurately position the blank at the next station. Therefore, it cannot meet the requirement of precise blank positioning before proceeding to the next forming step, otherwise, excessive errors will occur in the next operation. Some existing methods use rollers to convey the blank to its position and then align it; however, this method is unsuitable if there are gaps between stations, and it is generally not suitable for feeding some forming molds. There are also suction transfer methods, but before suction transfer, the length and positioning of the blank requires manual intervention or a complex robotic arm, resulting in high labor or equipment costs.

[0004] During the forming process, the sheet blank is typically fed by rollers and then rolled to gradually create the folded edge, similar to the method used in patent CN 211390114 U. This forming method is slow, has limited pressure, and low production efficiency. It is even slower when forming harder metal storage tanks. Moreover, the folded corners produced by this rolling method have a large radius, which is not suitable for high-precision products with small folding requirements, especially those requiring two folds. Currently, there are also some stamping folding forming methods. Some require manual operation, resulting in slow production speed, while others use hydraulic cylinders, which have higher equipment costs, such as patent CN 216175676 U. However, these methods are not convenient for forming secondary folds.

[0005] During the shaping process, the process usually involves rolling and shaping with rollers, which results in small stamping and slow speed. Similarly, it is even slower when forming harder metal storage grooves, and the resulting folded edge angle is still relatively large. In particular, it is difficult to achieve a small arc transition when shaping two folded edges, so it cannot be adapted to high-precision products with small folded angle requirements.

[0006] Therefore, people hope to find a more refined and smoother production method for manufacturing harder metal storage recess components. Summary of the Invention

[0007] The purpose of this invention is to provide an automated production line for producing micro iron core storage slots that is fast, efficient, and has high precision in folding the finished product.

[0008] This invention is achieved through the following technical solution:

[0009] The automated production line for micro iron core storage slots includes an automatic material feeding device for storage slots, a storage slot forming device, and a shaping and unloading device arranged in sequence.

[0010] The automatic material pulling device for the receiving slot includes a fixed base and a material pulling platform mounted on the fixed base via a support rod. A slot is formed in the middle of the material pulling platform, and a clamping cylinder is installed within the slot. The clamping cylinder is driven to move by the material pulling cylinder.

At the end of the material pulling platform, there is a limiting block to limit the position to which the blank is pulled by the clamping cylinder, facilitating blank positioning. Above the material pulling platform, there is an electromagnet fixed to the movable end of a suction cylinder via a support rod. The suction cylinder is fixed to the movable block of a rodless material transfer cylinder. After material pulling is completed, the suction cylinder drives the electromagnet to move downwards to pick up the blank, and then, driven by the rodless material transfer cylinder, the blank is sent to the receiving slot forming device for forming.

[0011] Preferably, the front end of the automatic feeding device for the receiving trough is further provided with a feeding, punching, and cutting device for conveying sheet blanks into its feeding platform. The feeding, punching, and cutting device is equipped with a punching mechanism, a cutting mechanism, and a conveying mechanism.

[0012] Preferably, a linear guide rail is provided between the material-tapping plate and the fixed base, so that the material-tapping cylinder can drive the material-tapping plate to move along the linear guide rail to maintain the accuracy of the material-tapping plate, thereby ensuring that the blank is tapped into place and ensuring the accuracy of the next forming step.

[0013] The storage slot forming device includes a support base and a forming mold mounted on the support base. The forming mold includes a fixed lower forming mold and a movable upper forming mold. The movable upper forming mold is fixedly connected to the movable end of a pressing forming cylinder. The pressing forming cylinder is fixedly mounted on a support fixed on the support base. The movable upper forming mold has an inverted T-shaped structure. The fixed lower forming mold has a groove in the middle that matches the bottom width of the inverted T-shaped structure of the movable upper forming mold. A movable block facing upward is provided in the groove by a spring, so that the two sides of the blank can be folded once when the movable upper forming mold is pressed down. On both sides of the fixed lower forming mold, a pair of insert plates driven by insert plate cylinders are also symmetrically provided to fold the two sides of the blank a second time to form a molded product. On the support base, corresponding to the initial position before the movable upper forming mold is pressed down, a movable material-pushing block is also provided to push the molded product on the movable upper forming mold backward and detach it from the movable upper forming mold.

[0014] Preferably, the insert cylinder is fixed to the support base.

[0015] Preferably, the movable feeding block is driven to move by a forming feeding cylinder, which is fixedly mounted on the support.

[0016] The shaping and unloading device includes a base and a shaping fixed upper mold mounted on the base via a support plate. Below the shaping fixed upper mold, there is a shaping movable lower mold with an inverted T-shaped structure that can cooperate with it. The shaping movable lower mold is driven by an upward shaping cylinder mounted on the support plate. The shaping fixed upper mold has a convex groove that adapts to the inverted T-shaped structure of the shaping movable lower mold. Below the support plate, at a height relative to the initial position of the shaping movable lower mold before it is pushed up, there is a movable unloading block to facilitate pushing the shaped product on the shaping movable lower mold backward and detaching it from the shaping movable lower mold.

[0017] Preferably, the movable feeding block is mounted on the movable end of an obstacle avoidance cylinder via a rod.

[0018] Preferably, the upper end of the lower shaping mold is connected to a connecting frame that is connected to the movable end of the upper shaping cylinder, and the connecting frame passes through the upper shaping mold.

[0019] Preferably, the rear end of the shaping lower mold is also provided with a baffle plate whose upper end is spring-loaded on the support plate, which is used to hold the edge of the molded product in place before it is unloaded to prevent it from moving forward.

[0020] The initial position of the upper molding die before pressing down and the initial position of the lower shaping die before lifting up are at the same height, so that the movable material-pushing block can push the molded product on the upper molding die to the lower shaping die for shaping.

[0021] Preferably, the surfaces of the fixing seat, the support seat, and the base are at the same height and are integrally formed.

[0022] Preferably, each cylinder-driven component is equipped with a guide device to facilitate more precise movement during the driving process.

[0044] like Figure 1-18 As shown, the automated production line for micro iron core storage slots includes a feeding, punching, and cutting device 10, an automatic material pulling device for storage slots 20, a storage slot forming device 30, and a shaping and unloading device 40, arranged sequentially.

[0045] The feeding, punching, and cutting device 10 is a commonly used feeding, punching, and cutting device on the market, which internally includes a punching mechanism, a cutting mechanism, and a conveying mechanism. It is used to feed sheet-shaped blanks 100 into the feeding platform 22 of the automatic feeding device 20 of the receiving trough.

[0046] The automatic material pulling device 20 for the receiving slot includes a fixed base 21 and a material pulling platform 22 mounted on the fixed base 21 via a support rod. A slot is formed in the middle of the material pulling platform 22, and a clamping cylinder 23 is installed within the slot. The clamping cylinder 23 is driven to move by a material pulling cylinder 24. On both sides of the slot, there are blank guide plates 25. On both sides of the slot and at the front and rear positions of the blank guide plates 25, there are also two symmetrically arranged material tapping plates 27, each driven by a material tapping cylinder 26 fixed to the fixed base 21. At the end of the material pulling platform 22… A limiting block 28 is also provided to limit the position of the blank 100 when it is pulled by the clamping cylinder 23, so as to facilitate the positioning of the blank 100. Above the pulling platform 22, there is also an electromagnet 29 fixed to the movable end of the suction cylinder 29.1 by a support rod. The suction cylinder 29.1 is fixedly mounted on the movable block of a transfer rodless cylinder 29.2. After the material is pulled, the suction cylinder 29.1 drives the electromagnet 29 to move down to suck up the blank 100. Then, under the action of the transfer rodless cylinder 29.2, the blank 100 is sent to the receiving tank forming device 30 for forming.

[0047] A linear guide rail 27.1 is provided between the material-applying plate 27 and the fixed base 21 so that the material-applying cylinder 26 can drive the material-applying plate 27 to move along the linear guide rail 27.1 to maintain the linear accuracy of the movement of the material-applying plate 27, thereby ensuring that the blank 100 is approximated in place and ensuring the accuracy of the next forming step.

[0048] This automatic material feeding device for the storage slot is continuous and smooth in clamping, feeding, guiding, aligning and absorbing the blank. It has good coordination and a high degree of automation. It can realize continuous, precise and automatic feeding, alignment and transfer, which can meet the precise feeding requirements of the forming mold and has high efficiency.

[0049] The storage slot forming device 30 includes a support base 31 and a forming mold mounted on the support base 31. The forming mold includes a fixed lower forming mold 32 and a movable upper forming mold 33. The movable upper forming mold 33 is fixedly connected to the movable end of a pressing forming cylinder 34. The pressing forming cylinder 34 is fixedly mounted on a support 35 fixed to the support base 31. The movable upper forming mold 33 has an inverted T-shaped structure. The fixed lower forming mold 32 has a groove in the middle that matches the bottom width of the inverted T-shaped structure of the movable upper forming mold 33. An upward-facing movable block 36 is provided in the groove via a spring, so that the two sides of the blank 100 can be folded once when the upper mold 33 is pressed down. On both sides of the lower mold 32, a pair of insert plates 38 driven by insert plate cylinders 37 are also symmetrically provided to fold the two sides of the blank 100 a second time to form the molded product 200. On the support base 31, corresponding to the initial position before the upper mold 33 is pressed down, a movable material-pushing block 39 is also provided to push the molded product 200 on the upper mold 33 backward and disengage it from the upper mold 33.

[0050] The insert cylinder 37 is fixed on the forming and fixing lower mold 32 or on the support base 31.

[0051] The movable feeding block 39 is driven to move by the forming feeding cylinder 39.1, which is fixedly mounted on the support 35.

[0052] This automatic forming device for the storage tank automates both folding processes of the sheet blank. It features large stamping capacity, high folding angle accuracy, fast folding speed, high production efficiency, good feeding accuracy, and high forming precision, enabling the storage tank to meet the placement requirements of micro iron cores with high precision.

[0053] The shaping and unloading device 40 includes a base 41 and a shaping fixed upper mold 42 mounted on the base 41 via a support plate 44. Below the shaping fixed upper mold 42, there is a shaping movable lower mold 43 with an inverted T-shaped structure that can cooperate with it. The shaping movable lower mold 43 is driven by an upward shaping cylinder 45 mounted on the support plate 44. The shaping fixed upper mold 42 has a convex groove that adapts to the inverted T-shaped structure of the shaping movable lower mold 43. Below the support plate 44, at a height relative to the initial position of the shaping movable lower mold 43 before it is pushed up, there is a movable unloading block 46 to facilitate pushing the shaped product on the shaping movable lower mold 43 backward and detaching it from the shaping movable lower mold 43.

[0054] The movable feeding block 46 is mounted on the movable end of an obstacle avoidance cylinder 46.1 via a rod. The obstacle avoidance cylinder 46.1 is fixed on the movable end of a shaping feeding cylinder 46.2 mounted on a support plate 44, so as not to block the feeding of material onto the shaping movable lower mold 43.

[0055] The upper end of the lower shaping mold 43 is connected to a connecting frame 45.1 that is connected to the movable end of the upper shaping cylinder 45. The connecting frame 45.1 passes through the upper shaping fixed mold 42.

[0056] The rear end of the lower mold 43 for shaping is also provided with a baffle 47 whose upper end is spring-loaded on the support plate 44, which is used to hold the edge of the molded product in place before it is unloaded to prevent it from moving forward.

[0057] The initial position of the upper molding die 33 before pressing down and the initial position of the lower shaping die 43 before lifting up are at the same height, so that the movable material-pushing block 39 can push the molded product 200 on the upper molding die 33 to the lower shaping die 43 for shaping.

[0058] This shaping and unloading device completes the shaping of the two folded edges of the storage slot formed by two folds in one go. It has a high degree of automation, fast shaping, high production efficiency, large stamping capacity, and high shaping precision, which enables the storage slot to meet the placement of micro iron cores with high precision requirements, and the unloading is also fast and convenient.

[0059] The surfaces of the fixed base 21, the support base 31, and the base 41 are at the same height and can be integrally formed.

[0060] Each cylinder-driven component is equipped with a guide device to facilitate more precise movement during the driving process.

[0061] Work process:

[0062] The coil material is fed from the feeding, punching and cutting device, which punches and cuts the coil material and then conveys the cut blank to the front end of the feeding platform of the automatic feeding device in the receiving trough.

[0063] On the feeding platform of the automatic feeding device for the receiving slot, after the clamping cylinder clamps the blank, it is pulled forward by the feeding cylinder. After the blank hits the limit block, the clamping cylinder releases the blank, and the clamping cylinder continues to retreat a certain distance under the drive of the feeding cylinder to avoid obstruction when the electromagnet pulls the blank upward. Then, the tapping cylinder drives the tapping plate to tap the blank to straighten it. Then, the electromagnet above the feeding platform is driven by the suction cylinder to pull the blank downward and moves forward under the drive of the rodless transfer cylinder to send the accurately positioned blank to the receiving slot forming device for forming to ensure the subsequent forming accuracy. Specifically, it is sent to the forming fixed lower mold.

[0064] On the storage slot forming device, the inverted T-shaped forming movable upper mold is pushed down into the groove of the forming fixed lower mold by the pressing forming cylinder to perform the first edge folding of the blank. Then the forming fixed lower mold remains stationary, and the insert plates on both sides of the forming fixed lower mold are pushed into the middle by the insert plate cylinder to perform the second edge folding of the blank, so that the blank is completely closed onto the inverted T-shaped forming movable upper mold. Then the forming movable upper mold moves upward with the molded product, and the movable material ejector block is driven by the forming material ejector cylinder to eject the molded product onto the shaping movable lower mold, which is also an inverted T-shaped structure.

[0065] In the shaping and unloading device, the movable lower die moves upward under the push of the upward shaping cylinder to press the fixed upper die, thus completing the shaping. After shaping, the movable unloading block moves forward a certain distance under the drive of the avoidance cylinder to the position of the molded product on the movable lower die. Then, the movable unloading block pushes the shaped product outward under the drive of the shaping unloading cylinder, thus unloading. During this process, the baffle at the rear end of the movable lower die holds the edge of the molded product to prevent it from moving forward before unloading. When the movable unloading block pushes the shaped product outward, the baffle is pushed open, and the product is unloaded smoothly. After unloading, the movable unloading block moves backward a certain distance under the drive of the avoidance cylinder to avoid blocking the movable unloading block from pushing the product onto the movable lower die.

[0066] The automated production line for micro iron core storage slots of this invention has an ingenious structure and a high degree of automation. Through the cooperation of a feeding, punching and cutting device, an automatic material pulling device for storage slots, a storage slot forming device, and a shaping and unloading device, the blank can be quickly formed into a micro iron core storage slot with accurate and precise folding. This allows the micro iron cores 300 to be wound with copper wire to be stored one by one in the slots. The feeding of the micro iron cores into the winding device is like a bullet clip, which can achieve continuous, precise and automatic feeding. This replaces manual feeding of each micro iron core into the winding device, greatly saving the labor cost of the winding process and significantly improving the production efficiency of the winding process. It is highly practical and worthy of promotion.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
