Description

TECHNICAL FIELD

[0001] The application relates to the field of magneto-electric activation mechanisms, in particular to a stamping device for producing a magneto-electric activation mechanism and a method thereof. BACKGROUND

[0002] A magneto-electric activation mechanism is a device that uses electromagnetic interaction principles to achieve specific mechanical actions or functions, and is widely used in automatic control, electronic equipment, precision instruments and other fields. Its core working mechanism is to trigger magnetic effect through electrical signals, and then drive mechanical components to move to complete functions such as switch closing, component attraction, displacement control, etc. The electromagnetic system of the electromagnetic system includes a coil, a core, and an armature. The coil generates a magnetic field by being energized and is the energy input component of the magneto-electric activation. The number of turns, wire diameter and current size of the coil determine the magnetic field strength. The core is usually made of high-permeability materials such as silicon steel sheets and soft iron, which is used to concentrate and guide the magnetic field and enhance the efficiency of the magnetic circuit. The armature is a movable component that is affected by the magnetic field force and is usually made of magnetic materials such as iron and steel. Its shape is designed according to the functional requirements, such as U-shaped, E-shaped, cuboid, etc., and is formed by stamping and other processes. It can be attracted or repelled in the magnetic field. The cross-sectional shape of the armature needs to match the cross-sectional shape of the core to reduce the magnetic resistance and improve the magnetic flux. If the cross-section of the core is rectangular, the cross-section of the armature is usually designed to be rectangular to form a symmetrical closed magnetic circuit. If the magnetic circuit is cylindrical, such as a solenoid electromagnet, the cross-section of the armature is circular and matches the inner diameter of the coil.

[0003] Based on the comprehensive design of the magnetic circuit optimization, mechanical integration and process efficiency of the magneto-electric activation mechanism, the core purpose is to improve the electromagnetic performance and structural reliability in a specific scenario. The armature is usually stamped into a U-shaped shape with a "V" shaped cross-section or a three-dimensional U-shaped cross-section by a stamping device. The magnetic flux is transmitted through the two arms of the U-shaped structure. Compared with single-pole structures such as circular armatures, the total cross-sectional area of the magnetic circuit is increased, the magnetic resistance is reduced, and the electromagnetic attraction force can be increased by about 30%-50%. The symmetrical distribution of the magnetic attraction force on both sides can offset the lateral force during the movement of the armature, reducing the friction with the guide groove. For example, in an electromagnetic valve, the U-shaped armature cooperates with a double-column core, and the movement is more stable. The horizontal arm of the U-shaped armature forms a closed magnetic circuit with the top of the core, and the two arms on the open side serve as the main channel for the magnetic flux. For example, in an AC contactor, the U-shaped armature cooperates with an E-shaped core. The two arms on both sides correspond to the two columns of the core, and the horizontal arm corresponds to the middle column. When the magnetic circuit is closed, the leakage magnetic flux is reduced by 15%-20%, and the energy efficiency is improved.

[0004] In the existing stamping device, the stamping die is mostly fixed structure, and it is difficult to adapt to the width requirement of different U-shaped armatures. For example, the opening width of different types of U-shaped armatures of common AC contactors is different. Due to the fixed cavity size of the traditional die, only stamping of a specific width specification can be achieved, and the same die cannot produce different width U-shaped armatures. If U-shaped armatures of multiple width specifications need to be produced, different dies need to be replaced, which increases the production cost and downtime. SUMMARY

[0024] A method for producing a stamping device using a magnetoelectric activation mechanism further includes the following steps: S1: Based on the design drawings of the U-shaped armature to be stamped, confirm its width, side tilt angle and other specifications; check the status of each component of the stamping device, including the oil circuit sealing of the hydraulic drive mechanism 4, the stroke accuracy of the electric push rod 402, and the meshing tightness of the gear 302 and rack 304, to ensure that the equipment is fault-free; S2: Start the hydraulic rods 204 on both sides of the forming groove 201 of the base 203, drive the stop block 202 to slide along the slide according to the armature width requirement, and precisely adjust the distance between the two stop blocks 202 to complete the adaptation of the width of the forming groove 201. S3: After the stop block 202 is adjusted into place, use a vernier caliper or digital caliper to measure the actual width of the forming groove 201. The error must be controlled within ±0.1mm. S4: Start the electric push rod 402 to drive the moving frame 303 to rise and fall. Through the transmission of the rack 304 and the gear 302, the central shaft 305 of the punch head 5 is rotated, and the arc surface angle of the two punch heads 5 is adjusted to be consistent with the inclination of the side of the U-shaped opening of the armature. S5: Use an angle gauge to detect the initial angle of the punch head 5. If the deviation exceeds ±0.5°, perform a second fine adjustment. S6: Start the hydraulic cylinder 401 to control the lifting frame 403 to drive the guide column mechanism 3 to descend, so that the punch head 5 contacts the protective pad 7, ensuring that the protective pad 7 forms a stable “V” shaped support structure. S7: If the protective pad 7 needs to be replaced, release the brake device of the take-up wheel 6, completely roll up and remove the old protective pad 7, install the new protective pad 7 and ensure that both ends are firmly wrapped around the take-up wheel 6. By adjusting the damping device of the take-up wheel 6, control the tension of the protective pad 7 so that it produces slight deformation but does not loosen when the protective pad 7 is pressed. S8: Take 1-2 same specification of the armature to be processed to test stamping, the armature is placed in the forming groove 201, positioned and fixed by the stop block 202, start the hydraulic cylinder 401 to drive the punch head 5 to stamp, at the same time control two punch heads 5 to rotate reversely synchronously, observe the forming effect of the armature after test stamping, detect its size accuracy and surface flatness, if the test stamping product is unqualified, analyze the reason and adjust the die set 2, the angle of the punch head 5 or the hydraulic pressure parameter again until the test stamping product meets the quality standard; S9: Put the batch of armatures to be processed in the forming groove 201 in turn, start the stamping device to carry out continuous stamping operation, pause the equipment after completing 50-100 stamping, check the wear of the protective pad 7, the surface state of the punch head 5 and the position stability of the stop block 202, if the protective pad 7 is obviously worn or torn, replace it in time; S10: The U-shaped armature after stamping is subjected to deburring, cleaning and other post-processing procedures, ultrasonic cleaning machine is used to remove surface oil stains and metal debris, the surface residual debris of the die set 2 forming groove 201 and the stop block 202 is cleaned, lubricating oil is applied to the transmission parts such as the gear 302, the rack 304 and the sliding groove, the power of the equipment is turned off, the product specification, quantity and equipment running condition of this production are recorded to provide data reference for subsequent production.

[0025] Working principle: In the mold set 2, two movable blocks 202 are arranged in the forming groove 201 of the base 203 and are driven by the hydraulic rod 204. When different width U-shaped armatures are needed to be produced, the output end of the hydraulic rod 204 is telescoped to push the blocks 202 to slide along the sliding groove in the forming groove 201 to adjust the distance between the blocks 202. The cooperation between the sliding block and the sliding groove ensures the stable movement of the blocks 202 and avoids deviation, so as to change the width of the forming groove 201 and adapt to the positioning requirements of armatures of different specifications; in the guide column mechanism 3, the moving frame 303 is connected with the lifting frame 403 of the hydraulic drive mechanism 4 through the electric push rod 402. When the angle of the stamping head 5 needs to be adjusted, the electric push rod 402 drives the moving frame 303 to lift, and the rack 304 on the moving frame 303 moves accordingly. Since the rack 304 is engaged with the gear 302, the lifting of the rack 304 drives the rotation of the gear 302, and then the rotation of the central shaft 305 fixed with the gear 302, finally the angle adjustment of the stamping head 5 is realized. The contact surface of the stamping head 5 is an arc surface with a radius increasing along the circumference, and by synchronous reverse rotation of the two stamping heads 5, the included angle between the two stamping heads 5 can be changed to adapt to the inclination angle of the openings of different U-shaped armatures; in the hydraulic drive mechanism 4, the hydraulic cylinder 401 is fixed on the upper part of the frame 1, and the output end thereof is connected with the lifting frame 403. After the hydraulic cylinder 401 is started, the lifting frame 403 drives the guide column mechanism 3 to descend as a whole, so that the stamping head 5 contacts the protective pad 7. The protective pad 7 is wound around the winding wheel 6 at both ends, and forms a "V" type structure under the extrusion of the stamping head 5. It should be noted that the two winding wheels 6 can be externally connected with motors, and the rotation of the winding wheel 6 is realized by the motor drive, so that the winding and unwinding of the protective pad 7 is realized. At this time, the armature to be processed is placed at the blocks 202 of the forming groove 201 and located at the groove 8 of the blocks 202, the hydraulic cylinder 401 continues to press, and the stamping head 5 extrudes the armature through the protective pad 7 to complete the forming processing of the armature; it should be noted that the mold cavity of the traditional stamping die is fixed and cannot adapt to different width U-shaped armatures. The device can quickly adjust the width of the forming groove 201 through the movable blocks 202 in the mold set 2, and adjust the contact angle by the synchronous reverse rotation of the stamping head 5, like Figures 3-5As shown, since the contact surface of the stamping head 5 is an arc surface, and the radius of the arc surface of the contact surface increases along the circumference of the stamping head 5, when the stamping head 5 rotates synchronously and reversely, the distance between the contact points of the two stamping heads 5 away from each other can be adjusted, the compatibility of U-shaped armatures with different widths and different opening inclinations U can be realized, and the problem of frequent replacement of traditional molds is solved. Therefore, through the self-adaptive adjustment of the mold set 2 and the stamping head 5, various specifications of U-shaped armatures can be produced, the mold replacement frequency is reduced, the mold purchase cost and maintenance cost are reduced, the downtime caused by mold replacement is reduced, the production efficiency is improved, and the bottom position of the two stamping heads 5 can extrude the protective pad 7 to stamp and form the armature during stamping. Through the cooperation of the protective pad 7 and the winding wheel 6, the protective pad 7 acts as a buffer medium during stamping to avoid direct contact between the stamping head 5 and the armature, effectively preventing indentation and scratches on the surface of the armature. At the same time, the protective pad 7 disperses the stamping stress, reduces the damage of the armature caused by instantaneous impact force, reduces the wear of the stamping head 5, and prolongs the service life of the mold. It should be noted that since the protective pad 7 will be worn out after a long time of use, the winding wheel 6 can control the protective pad 7 to move along the stamping head 5, so that the new part of the protective pad 7 contacts the stamping head 5, thereby improving the service life of the protective pad 7.

[0026] Then, since the contact surface of the stamping head 5 is an arc surface, and the radius of the arc surface of the contact surface increases along the circumference of the stamping head 5, the contact point is more easily smoothly transitioned when the stamping head 5 rotates, and when the contact radius of the stamping head 5 increases or decreases, that is, the arc surface of the stamping head 5 forms a rolling trend with the protective pad 7 when rotating, so that the resistance when rotating is smaller, and the energy consumption is reduced.
