Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a high-precision continuous stamping die for automatic stacking and riveting of pen-type iron cores. Background Technology
[0002] A pen-shaped iron core is an iron core with a specific shape and function, widely used in electromagnetic devices such as motors, transformers, and sensors. Its main characteristics are a pen-shaped (i.e., slender or columnar) shape with grooves on both sides, and it is usually composed of multiple stacked laminations.
[0003] Pen-type steel cores typically have variable cross-sections, with different sections having inconsistent cross-sections. This design makes it difficult to use traditional positioning methods to ensure the correct stacking of each core piece during assembly. Traditional positioning methods usually rely on steel core pieces with regular shapes (such as rectangles or circles), which cannot be directly applied to the non-uniform shape of pen-type steel cores, thus increasing the complexity of positioning. Pen-type steel cores are generally composed of multiple silicon steel sheets of different sizes and shapes stacked together. The size, angle, and position of each steel core piece need to be precisely controlled to ensure that the final core geometry meets the requirements. Due to the diverse shapes of these steel core pieces and the need for precise alignment during assembly, any slight deviation can lead to positioning errors, making the positioning process even more difficult. Especially in automated assembly processes, accurately stacking steel core pieces of different shapes and sizes and avoiding misalignment becomes a major challenge. Furthermore, the complex shape and diversity of pen-type steel cores mean that there is no clear and reusable reference point for positioning. In manual or automatic positioning processes, fixed alignment marks cannot be relied upon; each steel core piece needs to be handled and precisely aligned individually, which further increases the difficulty of positioning.
[0004] In view of this, we propose a pen-type automatic stacking and riveting high-precision stamping continuous die for iron cores. Utility Model Content
[0005] The purpose of this utility model is to provide a high-precision continuous stamping die for automatic stacking and riveting of pen-type iron cores. This high-precision continuous stamping die for automatic stacking and riveting of pen-type iron cores solves the problem of complex positioning caused by the lack of fixed reference points during the assembly process due to the variable cross-sectional shape and diverse stacking configuration of pen-type iron cores.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A high-precision continuous stamping die for automatic stacking and riveting of iron cores includes a machine body. A support mechanism is provided on the top of the machine body. The support mechanism includes a support frame, a drive wheel, a conveyor belt, and a mounting base. An mounting mechanism is provided on the top of the mounting base. The mounting mechanism includes an iron core placement frame, which is inserted into the top of the mounting base. A positioning protrusion is provided on the inner wall of the iron core placement frame. One end of a telescopic tube is fixedly connected to the outer wall of the iron core placement frame. A positioning plate is fixedly connected to the other end of the telescopic tube. One end of a telescopic rod is fixedly connected to the outer wall of the positioning plate. The other end of the telescopic rod is fixedly connected to the outer wall of the iron core placement frame. One end of a first spring is fixedly connected to the outer wall of the positioning plate. The other end of the first spring is fixedly connected to the outer wall of the iron core placement frame. A connecting pipe is fixedly connected to the inner wall of the iron core placement frame. A fixing column is fixedly connected to the inner wall of the connecting pipe. One end of a second spring is fixedly connected to the outer wall of the fixing column. The other end of the second spring is fixedly connected to a guide plate. A pressing mechanism is provided on the outer wall of the machine body.
[0008] Preferably, the support frame is fixedly connected to the outer wall of the machine body, and the support frame is provided with drive wheels. There are two drive wheels, and the two drive wheels are connected by a conveyor belt. The conveyor belt is provided with a mounting base.
[0009] Preferably, the inner wall of the connecting pipe is connected to the inner wall of the telescopic pipe, and the outer wall of the guide plate is provided with a circular tube block.
[0010] Preferably, the cylindrical block of the guide plate is connected to the inner wall piston of the connecting pipe, and the guide plate is located on the outer surface of the positioning protrusion.
[0011] Preferably, there are several mounting bases arranged in an array.
[0012] Preferably, the pressing mechanism includes a support column, which is fixedly connected to the top of the machine body. A reciprocating cylinder is fixedly connected to the top of the support column, and a pressing head is fixedly connected to the output end of the reciprocating cylinder.
[0013] Preferably, a trigger rod is fixedly connected to the top of the pressing head, and the trigger rod is bent and tilted.
[0014] By employing the above technical solution, this utility model provides a high-precision continuous stamping die for automatic stacking and riveting of pen-type iron cores. It possesses at least the following beneficial effects:
[0015] (1) In this utility model, the reciprocating cylinder is activated to drive the pressing head downwards for riveting. At this time, the pressing head drives the inclined surface of the trigger rod downwards to first contact the positioning plate, causing the positioning plate to move towards the telescopic tube. The telescopic tube is compressed, causing the air inside the telescopic tube to flow into the connecting tube, creating positive pressure inside the connecting tube. The positive pressure inside the connecting tube causes the guide plate to tightly contact the groove part of the pen-type iron core, making it tightly fit the groove part of the pen-type iron core. Through this process, the sheet of the pen-type iron core is precisely fixed and kept stable, providing reliable support for subsequent automatic riveting operations, thereby improving assembly accuracy and efficiency and avoiding misalignment problems.
[0016] (2) In this utility model, when the riveting is finished, the reciprocating cylinder drives the pressing head to move upward, the pressing head drives the trigger rod to move upward, the trigger rod no longer touches the positioning plate, at this time the spring drives the positioning plate to move away from the iron core placement frame, and drives the telescopic tube to stretch. At this time, the air pressure in the connecting tube is reduced to the normal level, so that the riveted pen-type iron core can be easily taken out.
[0017] (3) In this utility model, the conveyor belt is used as the main transmission medium to transmit the power provided by the drive wheel to the mounting seat, so that the mounting seat can reciprocate in the required direction to complete certain material handling and positioning functions, so that the work station where the worker places the work and the pressing part are separated. This separation design not only reduces the interference of the operator in the equipment and avoids potential mechanical injury, but also improves the stability and efficiency of the operation, because the worker only needs to focus on the placement and adjustment of the workpiece, and does not need to worry about pressing or riveting operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-7 As shown, this utility model provides a technical solution: a high-precision continuous stamping die for automatic stacking and riveting of pen-type iron cores, including a machine body 1. A support mechanism 2 is provided on the top of the machine body 1. The support mechanism 2 includes a support frame 21, a drive wheel 22, a conveyor belt 23, and a mounting base 24. A mounting mechanism 3 is provided on the top of the mounting base 24. The mounting mechanism 3 includes an iron core placement frame 31, which is inserted into the top of the mounting base 24. A positioning protrusion 32 is provided on the inner wall of the iron core placement frame 31 for positioning the grooves on both sides of the pen-type iron core, ensuring that the iron core maintains a stable position during assembly. A telescopic tube 33 is fixedly connected to the outer wall of the iron core placement frame 31. One end of the telescopic tube 33 is fixedly connected to the other end of the positioning plate 34. One end of the telescopic rod 35 is fixedly connected to the outer wall of the positioning plate 34. The other end of the telescopic rod 35 is fixedly connected to the outer wall of the iron core placement frame 31. One end of the spring 36 is fixedly connected to the outer wall of the positioning plate 34. The other end of the spring 36 is fixedly connected to the outer wall of the iron core placement frame 31. A connecting tube 37 is fixedly connected to the inner wall of the iron core placement frame 31. A fixing post 38 is fixedly connected to the inner wall of the connecting tube 37. One end of the spring 39 is fixedly connected to the outer wall of the fixing post 38. The other end of the spring 39 is fixedly connected to the guide plate 310. A pressing mechanism 4 is provided on the outer wall of the machine body 1.
[0029] The support frame 21 is fixedly connected to the outer wall of the machine body 1. The support frame 21 is equipped with two drive wheels 22, which are connected by a conveyor belt 23. The conveyor belt 23 is equipped with a mounting seat 24. The drive wheels 22 drive the conveyor belt 23 to move back and forth, and the conveyor belt 23 drives the mounting seat 24 to move back and forth. The conveyor belt 23, as the main transmission medium, transmits the power provided by the drive wheels 22 to the mounting seat 24, enabling the mounting seat 24 to move back and forth in the required direction to complete certain material handling and positioning functions. This separates the workstation where the worker places the workpiece from the pressing part. This separation design not only reduces the interference of the operator in the equipment and avoids potential mechanical injuries, but also improves the stability and efficiency of the operation, because the worker only needs to focus on the placement and adjustment of the workpiece, without having to worry about pressing or riveting operations.
[0030] The inner wall of the connecting pipe 37 communicates with the inner wall of the telescopic pipe 33 to facilitate gas flow. A circular tube block is provided on the outer wall of the guide plate 310, and this circular tube block is piston-connected to the inner wall of the connecting pipe 37. The guide plate 310 is located on the outer surface of the positioning protrusion 32. When high pressure exists within the connecting pipe 37, the high pressure abuts against the guide plate 310, causing each guide plate 310 to move away from the positioning protrusion 32. This allows the guide plates 310 to further and more tightly contact the grooves of the pen-shaped iron core, achieving precise positioning and clamping of the iron core. This design helps to stably position the iron core during the assembly process, ensuring accurate docking and fixation of the iron core chips, avoiding misalignment or loosening, and thus improving the accuracy of automatic riveting and assembly efficiency.
[0031] There are several mounting bases 24, which are arranged in an array.
[0032] The pressing mechanism 4 includes a support column 41, which is fixedly connected to the top of the body 1. A reciprocating cylinder 42 is fixedly connected to the top of the support column 41. A pressing head 43 is fixedly connected to the output end of the reciprocating cylinder 42. A trigger rod 44 is fixedly connected to the top of the pressing head 43. The trigger rod 44 is bent and tilted. When the reciprocating cylinder 42 drives the pressing head 43 to move downward, the pressing head 43 will drive the trigger rod 44 to first contact the positioning plate 34, so that the positioning plate 34 squeezes the telescopic tube 33.
[0033] In use, the high-precision stamping continuous die for automatic stacking and riveting of pen-type iron cores of this utility model places the sheet-like components of the pen-type iron core into the iron core placement frame 31, and aligns the grooves on both sides of the pen-type iron core with the positioning protrusions 32. At this time, the positioning protrusions 32 do not make tight contact with the inner walls of the grooves on both sides of the pen-type iron core, which facilitates the placement of the pen-type iron core.
[0034] Then, drive wheel 22 drives conveyor belt 23, which in turn drives mounting base 24. Mounting base 24 drives mounting mechanism 3 to the bottom of pressing head 43. Then, reciprocating cylinder 42 is activated, driving pressing head 43 to move downward for riveting. At this time, pressing head 43 drives the inclined surface of trigger rod 44 to first contact positioning plate 34, causing positioning plate 34 to move towards telescopic tube 33. Telescopic tube 33 is compressed, causing air inside telescopic tube 33 to flow into connecting tube 37, creating positive pressure inside connecting tube 37. The positive pressure inside connecting tube 37 causes guide plate 310 to tightly contact the groove part of pen-type iron core, making it tightly fit the groove part of pen-type iron core. Through this process, the sheet of pen-type iron core is precisely fixed and kept stable, providing reliable support for subsequent automatic riveting operations, thereby improving assembly accuracy and efficiency and avoiding misalignment problems.
[0035] When the riveting is finished, the reciprocating cylinder 42 drives the pressing head 43 to move upward, and the pressing head 43 drives the trigger rod 44 to move upward. The trigger rod 44 no longer touches the positioning plate 34. At this time, the spring 36 drives the positioning plate 34 to move away from the iron core placement frame 31, and drives the telescopic tube 33 to stretch. At this time, the air pressure in the connecting tube 37 drops to the normal level, so that the riveted pen-shaped iron core can be easily removed.
