Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a feeding device for cutting machining in the preparation of manganese-zinc ferrite magnetic cores. Background Technology

[0002] Manganese-zinc ferrite cores, as important electronic magnetic materials, are widely used in the manufacture of electronic components such as transformers and inductors. In the fabrication process of manganese-zinc ferrite cores, machining is a crucial forming step, and the performance of the feeding device directly affects the machining accuracy, production efficiency, and product quality. Currently, the feeding devices for machining manganese-zinc ferrite cores still have some technical shortcomings and urgently need improvement.

[0003] A search revealed a patent, CN112536467A, concerning a fixed-length feeding device for iron core raw materials based on ferrite core cutting, published on March 23, 2021. This patent uses a base and a cutting plate to move the magnetic core body, and the connection between the cutting plate and the cutting blade enables core cutting. The cutting length is adjusted via a drive rod, lead screw, and baffle. However, this technical solution has the following shortcomings: First, the feeding mechanism uses a simple push-type feeding method, which can easily lead to unstable feeding and low positioning accuracy for irregularly shaped or significantly dimensionally skewed manganese-zinc ferrite cores. Second, the device primarily targets fixed-length cutting of iron core raw materials and does not consider surface cleaning of the manganese-zinc ferrite core during the cutting process; impurities on the core surface can affect subsequent processing quality and product performance. Third, the structural design is relatively complex; adjusting the cutting length requires the coordinated movement of multiple components such as the drive rod, gears, and lead screw, making debugging and maintenance inconvenient, and posing a risk of decreased accuracy due to mechanical wear.

[0004] A search revealed a feeding device for cutting ferrite cores, publication number CN215748012U, with an authorization announcement date of February 8, 2022. This patent utilizes a transmission mechanism, employing forward and reverse motors to drive a rotating shaft, a gearbox to stabilize the shaft's rotation, and a robotic arm assembly and a gripping assembly to grasp and transport the magnetic cores. However, this technical solution also has the following shortcomings: First, the structural design of the robotic arm assembly and the material gripping assembly is designed for general ferrite cores, and its adaptability to the special physical characteristics (such as hardness and brittleness) of manganese-zinc ferrite cores is poor, which can easily cause damage or chipping of the core surface during the gripping process; Second, the device does not have a universal adjustment mechanism for different specifications of manganese-zinc ferrite cores, and corresponding parts need to be replaced when changing product specifications, resulting in low versatility and limited production efficiency; Third, this technical solution lacks a cleaning function for the cores during the conveying process, and dust and impurities on the core surface can affect the cutting accuracy and tool life; Fourth, the transmission mechanism such as the gear set and speed reducer has a complex structure, occupies a large space, and is not conducive to the miniaturization and integration of the equipment.

[0005] The aforementioned prior art solutions indicate that existing feeding devices for cutting and machining manganese-zinc ferrite cores still have shortcomings in terms of feeding stability, versatility, core cleaning, and simplified equipment structure. Therefore, this invention provides a feeding device for cutting and machining manganese-zinc ferrite cores, aiming to solve the problems of unstable feeding, poor versatility, and lack of cleaning function in the prior art, thereby meeting the needs for efficient and precise machining of manganese-zinc ferrite cores. Summary of the Invention

[0006] This invention relates to the field of manganese-zinc ferrite core processing equipment, specifically to a feeding device for cutting processing in the preparation of manganese-zinc ferrite cores, aiming to solve the technical problems existing in the prior art, such as unstable feeding, poor versatility, lack of cleaning function, and complex equipment structure.

[0007] To achieve the above objectives, the present invention provides the following technical solution: Design a feeding device for cutting and machining in the fabrication of manganese-zinc ferrite cores, comprising a main frame, a mounting base plate, a power module, a transmission module, an execution module, and an auxiliary module, wherein: The main frame is made of aluminum alloy profiles and has adjustable feet at the bottom to support the entire device and achieve horizontal adjustment. The mounting base is made of steel plate with oblong holes for easy position adjustment and fixation. A protective cover is installed on the main frame. The protective cover is made of semi-transparent material and has a safety interlock switch to ensure safe operation.

[0008] The power module includes a drive motor, a planetary reducer, and a motor mounting base. The drive motor is fixed to the side wall of the main frame by bolts. The motor output shaft is connected to the input end of the planetary reducer through a flexible coupling. The reducer output shaft is connected to the ball screw through a coupling to realize power transmission.

[0009] The transmission module includes a ball screw, a screw support, a nut seat, and a linear guide. The ball screw is mounted on the main frame at both ends via the screw support. The fixed end uses an angular contact bearing, and the supporting end uses a deep groove ball bearing to ensure smooth rotation. The nut seat is bolted to the pusher plate, and the rotation of the ball screw drives the nut seat to perform linear reciprocating motion. The linear guide adopts a double guide structure, with a slider cooperating with the guide rail to constrain the degree of freedom of the pusher plate perpendicular to the conveying direction, ensuring the linearity of the movement.

[0010] The execution module includes a pusher plate, a flexible covering layer, a V-shaped material support groove, and a magnetic core tray. The pusher plate is made of aluminum alloy and is fixedly connected to the nut seat, moving horizontally under the drive of the lead screw nut. The front end of the pusher plate is covered with a flexible covering layer made of polyurethane material, which deforms flexibly when in contact with the magnetic core, avoiding hard contact that could cause chipping of the magnetic core edge. The V-shaped material support groove is adjustable, and its width can be adjusted according to the specifications of the magnetic core. It is made of nylon material, which has a lower hardness than the magnetic core, further protecting the surface of the magnetic core. The magnetic core tray is made of stainless steel, with moderate depth and anti-slip texture to prevent the magnetic core from sliding on the tray.

[0011] Furthermore, the V-shaped material tray is equipped with a material tray adjustment handle, which adopts a screw and handwheel structure, has high adjustment precision, and is equipped with a scale display. Users can quickly adjust it to the required width to achieve compatibility with different specifications of manganese zinc ferrite cores.

[0012] Furthermore, the execution module also includes a height adjustment block with various thicknesses. Users can select the appropriate block according to the core thickness to adjust the core tray height and ensure the accurate relative position of the core to the cutting station during transport.

[0013] Furthermore, the present invention includes a cleaning mechanism comprising a rotating brush, a brush motor, a high-pressure jet pipe, an air pump, a dust collection hood, and a vacuum cleaner. The rotating brush is a nylon bristle brush roller that rotates under the drive of the brush motor to physically scrub the surface of the magnetic core. The high-pressure jet pipe is located behind the brush, and its nozzle is an atomizing nozzle structure that sprays high-pressure airflow to blow away residual dust. The dust collection hood is made of transparent material to collect dust generated during the brushing and blowing process. The vacuum cleaner is connected to the dust collection hood through a suction pipe to discharge the dust. The cleaning mechanism is located on the conveying path, and the magnetic core passes through the cleaning mechanism before being pushed to the cutting station to complete the surface cleaning treatment.

[0014] Furthermore, the cleaning process of the cleaning mechanism is as follows: when the magnetic core enters the cleaning area, the rotating brush physically scrubs the surface, the high-pressure airflow blows away the residual dust, the dust collection hood collects the dust, and the vacuum cleaner discharges it, achieving a composite cleaning effect, significantly improving the surface cleanliness of the magnetic core, and providing good conditions for subsequent cutting processing.

[0015] Furthermore, the present invention includes a positioning and limiting mechanism, comprising a limiting baffle, a limit switch, a photoelectric sensor, and a proximity switch. The limiting baffle is a cylinder-driven telescopic structure, with the cylinder specifications adapted to the pusher plate stroke. Upon receiving a signal, it quickly extends or retracts to achieve rapid positioning and release of the magnetic core. The limit switch senses the extreme position of the pusher plate to prevent equipment damage. The photoelectric sensor is a through-beam type to detect whether the magnetic core is in position. The proximity switch senses the position of the material tray adjustment handle and feeds back the magnetic core specification information to the control system.

[0016] Furthermore, the working process of the positioning and limiting mechanism is as follows: after the photoelectric sensor detects that the magnetic core is in place, the control system issues a command, and the limiting baffle extends to block the magnetic core, thereby achieving precise positioning; after the cutting is completed, the cylinder retracts to release the magnetic core, and the pusher plate continues to push the next magnetic core, and the cycle repeats.

[0017] Furthermore, the present invention is provided with a sealing and dustproof mechanism, including a guide rail dust cover and a lead screw protective sleeve. The guide rail dust cover is foldable, made of rubber material, and covers the effective stroke of the linear guide rail to prevent dust from entering the guide rail and affecting the motion accuracy. The lead screw protective sleeve is a spiral steel wire sleeve, the length of which covers the effective stroke of the ball screw to prevent foreign objects from contaminating the lead screw threads.

[0018] Optionally, the main frame is assembled from standard aluminum alloy profiles, which is convenient to assemble, has a moderate weight, and is easy to move and arrange.

[0019] Optionally, the protective cover is equipped with a safety interlock switch, which automatically stops the equipment when the protective cover is opened to ensure the safety of the operator.

[0020] Optionally, the drive motor is a servo motor, which has a fast response speed, high control precision, and can achieve precise position control.

[0021] Optionally, the planetary reducer has a moderate reduction ratio, and the output torque meets the needs of pushing the magnetic core, ensuring smooth and reliable operation.

[0022] Optionally, the flexible coupling is a diaphragm type, which buffers and dampens vibrations and compensates for coaxiality errors.

[0023] Optionally, the coupling is of the plum blossom type, which is easy to install and transmits torque stably.

[0024] Optionally, the ball screw has a precision level that meets the pushing and positioning requirements, a reasonable lead design, and a smooth nut seat movement.

[0025] Optionally, the linear guide rail has a double slider structure, which has strong load-bearing capacity, high motion accuracy, and long service life.

[0026] Optionally, the pusher plate has a reasonable width and thickness design, and the aluminum alloy material is lightweight and high-strength, meeting the pusher rigidity requirements.

[0027] Optionally, the flexible coating layer has a moderate thickness and the polyurethane material has suitable hardness, so that it deforms appropriately when in contact with the magnetic core, which can both propel the magnetic core forward and not damage the surface of the magnetic core.

[0028] Optionally, the width adjustment range of the V-shaped material tray covers common manganese-zinc ferrite core specifications, and users can quickly adjust it according to actual needs.

[0029] Optionally, the anti-slip texture design of the magnetic core tray effectively prevents the magnetic core from shifting or falling during the pushing process.

[0030] Optionally, the rotation speed and nylon filament diameter of the rotating brush are designed to effectively clean the surface of the magnetic core without scratching it.

[0031] Optionally, the high-pressure jet pipe has a reasonable nozzle diameter and atomizing nozzle structure design, resulting in uniform airflow coverage and good cleaning effect.

[0032] Optionally, the exhaust pressure of the air pump meets the requirements for high-pressure airflow cleaning, and its operation is stable and reliable.

[0033] Optionally, the transparent design of the dust collection hood facilitates observation of the cleaning process and ensures good collection results.

[0034] Optionally, the vacuum cleaner's power is adapted to the dust collection capacity requirements, resulting in good dust collection performance and maintaining a clean working environment.

[0035] Optionally, the cylinder-driven method of the limiting baffle has a fast response speed and accurate and reliable positioning.

[0036] Optionally, the limit switch is installed in a reasonable position, which can effectively detect the extreme position of the pusher plate.

[0037] Optionally, the photoelectric sensor has high detection accuracy and fast response speed.

[0038] Optionally, the proximity switch can detect the adjustment position of the material tray and feed it back to the control system to achieve automatic adjustment.

[0039] Optionally, the height adjustment block can be designed in various specifications to meet the adjustment requirements of magnetic cores with different thicknesses.

[0040] Optionally, the guide rail dust cover has a foldable design for easy installation and replacement, and the rubber material has good wear resistance.

[0041] Optionally, the spiral design of the lead screw protective sleeve allows for free extension and retraction, providing good protection.

[0042] The beneficial effects of this invention are: by setting a dual guiding structure of V-shaped material support groove and linear guide rail, the pusher plate moves along the linear guide rail under the drive of ball screw, pushing the magnetic core forward along the V-shaped material support groove, effectively eliminating the skew problem in the pushing process, improving the feeding stability and positioning accuracy, and solving the problems of unstable feeding and low positioning accuracy of manganese zinc ferrite magnetic cores with irregular shape or large size deviation in the prior art.

[0043] By setting up a composite cleaning mechanism consisting of a rotating brush and high-pressure airflow, the surface of the magnetic core is brushed and blown before it is pushed to the cutting station. With the help of a dust collection hood and a vacuum cleaner to collect dust, the surface of the magnetic core is cleaned, removing dust and impurities before cutting, improving the quality of subsequent processing and product performance, and solving the problem that the cleaning treatment of the magnetic core surface is not considered in the existing technology.

[0044] By setting a flexible polyurethane coating layer at the front end of the pusher plate, the magnetic core is pushed by a soft contact method. The V-shaped material support groove is made of nylon, which has a lower hardness than the manganese zinc ferrite magnetic core, thus avoiding damage or chipping of the magnetic core surface caused by hard contact. This solves the problem that the mechanical arm can easily cause damage to the magnetic core surface in the existing technology.

[0045] By setting an adjustable-width V-shaped material tray and a height adjustment block, along with an adjustment handle with a scale, universal adaptation to different specifications of manganese-zinc ferrite cores can be achieved. The required parameters can be quickly adjusted without replacing parts, improving the equipment's versatility and production efficiency, and solving the problem of the lack of a universal adjustment mechanism in existing technologies.

[0046] By adopting a motor-reducer-screw nut drive method, the complex gear set speed reducer is eliminated, resulting in a simple and compact structure with a small footprint. This facilitates the miniaturization and integration of the equipment, while reducing mechanical wear, improving equipment precision and lifespan, and solving the problems of large space occupation and complex structure of gear set speed reducers in existing technologies.

[0047] By setting up a cylinder-driven telescopic limit baffle, the magnetic core can be quickly positioned and released, with fast response speed, accurate and reliable positioning, and improved work efficiency.

[0048] By installing dust covers on the guide rails and protective sleeves on the lead screws, dust and foreign objects can be effectively prevented from entering the moving parts, keeping the equipment clean, reducing maintenance frequency, and extending the service life of the equipment.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Specific implementation examples are given below.

[0053] See Figures 1-5 A feeding device for cutting and machining in the preparation of manganese-zinc ferrite cores includes a main frame 1, a mounting base plate 3, a power module, a transmission module, an execution module and an auxiliary module. The modules cooperate with each other to achieve stable delivery, precise cleaning and reliable positioning of manganese-zinc ferrite cores. The main frame 1 is constructed from standard aluminum alloy profiles. Aluminum alloy profiles are lightweight, high-strength, and corrosion-resistant, and the splicing structure facilitates assembly and disassembly. Adjustable feet 2 are installed at the bottom of the main frame 1. These feet are threaded and can be rotated to change the overall height of the device, achieving horizontal adjustment and ensuring the device remains level even on uneven ground, thus guaranteeing conveying accuracy. A protective cover 5 is installed on the main frame 1. The protective cover 5 is made of semi-transparent polycarbonate material, which allows operators to easily observe the equipment's operating status. The protective cover 5 is equipped with a safety interlock switch 6. When the protective cover 5 is opened, the safety interlock switch 6 triggers a signal, automatically stopping the equipment and ensuring operator safety. The mounting base plate 3 is made of steel plate with a thickness that meets the load-bearing strength requirements. The mounting base plate 3 has a slotted hole 4, which is a long and narrow hole structure that facilitates position adjustment and fixation. By adjusting the position of the bolts in the slotted hole 4, the position of the mounting base plate 3 on the main frame 1 can be finely adjusted to meet the needs of different installation environments. The power module includes a drive motor 7, a planetary reducer 8, and a motor mounting base 9. The drive motor 7 is a servo motor, which has a fast response speed, high control precision, and can achieve precise position control. The drive motor 7 is fixed to the motor mounting base 9 on the side wall of the main frame 1 by bolts. The motor output shaft is connected to the input end of the planetary reducer 8 through a flexible coupling 10. The planetary reducer 8 has a moderate reduction ratio, and the output torque meets the needs of pushing the magnetic core, and the operation is stable and reliable. The flexible coupling 10 is a diaphragm coupling. The diaphragm structure has the function of buffering and shock absorption, which can compensate for coaxiality errors and reduce vibration transmission. The output shaft of the planetary reducer 8 is connected to the ball screw 12 through a coupling 11. The coupling 11 is a plum blossom type coupling. The plum blossom type structure is easy to install and transmits torque stably. The transmission module includes a ball screw 12, a screw support 13, a nut seat 14, and a linear guide 15. The ball screw 12 is mounted on the main frame 1 at both ends via the screw support 13. The fixed end is supported by an angular contact bearing, which can withstand bidirectional axial loads, ensuring accurate axial positioning of the screw. The support end is supported by a deep groove ball bearing, which has low frictional resistance and smooth rotation. The accuracy grade of the ball screw 12 meets the pushing and positioning requirements, and the lead design is reasonable, ensuring smooth movement of the nut seat 14. The ball screw 12 is connected to the pusher plate 17 by bolts, and the rotation of the ball screw 12 drives the nut seat 14 to perform linear reciprocating motion. The linear guide 15 adopts a double guide rail structure. The slider 16 cooperates with the slide rail and is fixed on the pusher plate 17. The slider 16 and the slide rail of the linear guide 15 form a sliding cooperation, which restricts the degree of freedom of the pusher plate 17 in the direction perpendicular to the conveying direction, and ensures that the pusher plate 17 performs precise linear reciprocating motion along the linear guide 15. The linear guide 15 has a double slider structure, which has strong load-bearing capacity, high motion accuracy, and long service life. The execution module includes a pusher plate 17, a flexible covering layer 18, a V-shaped material support groove 19, and a magnetic core tray 20. The pusher plate 17 is made of aluminum alloy, which is lightweight and has high strength. The pusher plate 17 is fixedly connected to the nut seat 14 and moves horizontally under the drive of the lead screw nut. The width and thickness of the pusher plate 17 are designed to meet the pushing rigidity requirements. The front end of the pusher plate 17 is covered with a flexible covering layer 18, which is made of polyurethane material. Polyurethane material has good elasticity and wear resistance. When the flexible covering layer 18 comes into contact with the magnetic core, it undergoes flexible deformation, using a soft contact method to push the magnetic core, avoiding hard contact that could cause the magnetic core to chip. The thickness and hardness of the flexible covering layer 18 are moderate, which can push the magnetic core forward without damaging the surface of the magnetic core. The V-shaped material tray 19 is an adjustable structure, and its width can be adjusted according to the specifications of the magnetic core. The V-shaped material tray 19 is made of nylon, which has a lower hardness than manganese-zinc ferrite cores, further protecting the surface of the core. The V-shaped material tray 19 is equipped with a material tray adjustment handle 21, which adopts a screw and handwheel structure. Turning the handwheel drives the screw to move, causing the two side walls of the V-shaped material tray 19 to move relative to each other or move away, thereby adjusting the width of the tray. The material tray adjustment handle 21 has a scale display, allowing users to quickly read the current width value and adjust it to the required width, achieving universal compatibility with different specifications of manganese-zinc ferrite cores. The width adjustment range of the V-shaped material tray 19 covers common manganese-zinc ferrite core specifications. The core tray 20 is made of stainless steel, which has high strength and corrosion resistance. The core tray 20 has a moderate depth and anti-slip texture. The anti-slip texture design adopts a regular diamond grid pattern to effectively prevent the core from sliding or shifting on the tray. The execution module also includes a height adjustment block 22, which comes in various thicknesses, with typical thicknesses including 1 mm, 2 mm, 3 mm, and 5 mm. Users can select the appropriate pad according to the thickness of the magnetic core, place the height adjustment block 22 at the bottom of the magnetic core tray 20, and adjust the height of the magnetic core tray 20 to ensure that the relative position of the magnetic core with the cutting station is accurate during the conveying process. The auxiliary modules include a cleaning mechanism, a positioning and limiting mechanism, and a sealing and dustproof mechanism; The cleaning mechanism includes a rotating brush 23, a brush motor 24, a high-pressure jet pipe 25, an air pump 26, a dust collection hood 27, and a vacuum cleaner 28. The rotating brush 23 is a nylon bristle brush roller with a reasonable design for the diameter and hardness of the nylon bristles. Driven by the brush motor 24, the rotating brush 23 rotates to physically scrub the surface of the magnetic core. The nylon bristles can effectively scrub the surface of the magnetic core without scratching it. The brush motor 24 is mounted on the cleaning mechanism bracket and its speed is adjustable. The high-pressure jet pipe 25 is located behind the rotating brush 23. The nozzle of the high-pressure jet pipe 25 is an atomizing nozzle structure. The atomizing nozzle disperses the high-pressure airflow into fine particles and sprays out the high-pressure airflow. The airflow effectively removes residual dust, ensuring uniform coverage and excellent cleaning results. The exhaust pressure of the air pump 26 meets the requirements for high-pressure airflow cleaning, ensuring stable and reliable operation. The dust collection hood 27, made of transparent polycarbonate, allows for easy observation of the cleaning process. It covers the working area of ​​the rotating brush 23 and the high-pressure jet pipe 25, collecting dust generated during brushing and blowing. The vacuum cleaner 28 connects to the dust collection hood 27 via a suction pipe, and its power is adapted to the dust collection requirements, effectively expelling dust and maintaining a clean working environment. The cleaning mechanism is located on the conveying path; the magnetic core passes through the cleaning mechanism before being pushed to the cutting station, completing the surface cleaning process. The cleaning process of the cleaning unit is as follows: When the magnetic core enters the cleaning area, the rotating brush 23, driven by the brush motor 24, physically brushes the surface of the magnetic core to remove dust and impurities attached to the surface; the high-pressure jet pipe 25 sprays high-pressure airflow to blow away the surface of the magnetic core, further removing residual dust; the dust collection hood 27 collects the dust generated during brushing and blowing; the vacuum cleaner 28 discharges the dust through the suction pipe, achieving a composite cleaning effect, significantly improving the cleanliness of the magnetic core surface, and providing good conditions for subsequent cutting processing; The positioning and limiting mechanism includes a limit baffle 29, a limit switch, a photoelectric sensor, and a proximity switch. The limit baffle 29 is a telescopic structure driven by a cylinder 30. The cylinder 30 is adapted to the stroke of the pusher plate 17. The piston rod of the cylinder 30 is fixedly connected to the limit baffle 29. After receiving a signal, the cylinder 30 quickly extends or retracts to achieve rapid positioning and release of the magnetic core. The cylinder-driven method has a fast response speed and accurate and reliable positioning. The limit switch senses the extreme position of the pusher plate 17 to prevent equipment damage. The limit switch is installed in a reasonable position at both ends of the pusher plate 17's stroke, which can effectively detect the extreme position of the pusher plate 17. The photoelectric sensor is a through-beam photoelectric sensor with high detection accuracy and fast response speed. The transmitting end and receiving end are respectively set on both sides of the conveying channel. When the magnetic core reaches the detection position, the light is blocked, and the sensor outputs a signal. The proximity switch senses the position of the material tray adjustment handle 21 and feeds back the magnetic core specification information to the control system. The proximity switch detects the position status of the material tray adjustment handle 21 and feeds back to the control system to achieve automatic adjustment. The working process of the positioning and limiting mechanism is as follows: After the photoelectric sensor detects that the magnetic core is in place, it outputs a signal to the control system. The control system issues a command to control the cylinder 30 to move, and the limiting baffle 29 extends to block the magnetic core, so as to achieve precise positioning. After the cutting is completed, the cylinder 30 retracts, the limiting baffle 29 retracts, the magnetic core is released, and the pusher plate 17 continues to push the next magnetic core, and the cycle repeats. The sealing and dustproof mechanism includes a guide rail dust cover and a lead screw protective sleeve. The guide rail dust cover is foldable and made of rubber material. The foldable design facilitates installation and replacement, and the rubber material has good wear resistance. The guide rail dust cover covers the effective stroke of the linear guide rail 15, preventing dust from entering the interior of the linear guide rail 15 and affecting the motion accuracy. The lead screw protective sleeve is a spiral steel wire sleeve. The spiral design allows for free extension and retraction, providing good protection. Its length covers the effective stroke of the ball screw 12, preventing foreign objects from contaminating the threads of the ball screw 12. In this invention, the working steps of the device are as follows: First, place the manganese-zinc ferrite core to be processed on the core tray 20. The anti-slip texture of the core tray 20 prevents the core from sliding. Select an appropriate height adjustment block 22 according to the thickness of the core and place it at the bottom of the core tray 20. Adjust the height of the core tray 20 to make the relative position of the core and the cutting station accurate. Adjust the width of the V-shaped material support groove 19 according to the width of the core. Rotate the material support groove adjustment handle 21 and adjust the groove width to the appropriate size by reading the scale. Start the equipment and drive the motor 7 to run. The power is transmitted to the planetary reducer 8 through the flexible coupling 10. The planetary reducer 8 reduces the speed and increases the torque and then transmits it to the ball screw 12 through the coupling 11. The ball screw 12 rotates and drives the nut seat 14 to make linear reciprocating motion along the linear guide rail 15. The nut seat 14 drives the pusher plate 17 to move horizontally. The flexible covering layer 18 at the front end of the pusher plate 17 pushes the core forward along the V-shaped material support groove 19. Then, the magnetic core is pushed to the cleaning mechanism area, the rotating brush 23 rotates under the drive of the brush motor 24 to physically brush the surface of the magnetic core, the high-pressure jet pipe 25 sprays high-pressure airflow to blow the surface of the magnetic core, the dust collection hood 27 collects dust, the vacuum cleaner 28 discharges the dust, and the surface cleaning treatment is completed. The cleaned magnetic core is then pushed again. Next, after the photoelectric sensor detects that the magnetic core is in place, it sends a signal to the control system. The control system controls the cylinder 30 to move, and the cylinder 30 pushes the limit baffle 29 to extend. The limit baffle 29 blocks the magnetic core to achieve precise positioning, and the cutting station performs cutting processing on the magnetic core. Then, after the cutting is completed, the control system controls the cylinder 30 to retract, the limit baffle 29 to retract, the magnetic core is released, the pusher plate 17 continues to move forward, pushing the magnetic core to the next station, and at the same time pushing the next magnetic core to be processed into the positioning area, and repeating the cycle to achieve continuous processing. Finally, when the pusher plate 17 reaches the end of its stroke, the limit switch senses the limit position and sends a signal to the control system. The control system then controls the drive motor 7 to run in reverse, and the pusher plate 17 moves in reverse to reset, ready for the next pushing cycle.
