Description

Technical Field

[0001] The invention relates to the field of stamping and forming, and in particular to a high-efficiency motor iron core production device. Background Art

[0002] The motor core is a crucial component of the motor. Its performance directly impacts its efficiency and power density. The motor core, comprising the stator and rotor cores, is primarily made of silicon steel sheets, forming a single-layer, multi-sheet stack. In actual production, the motor core production process includes: feeding → stamping → stacking, riveting, welding → machining → injection molding, aluminum casting, winding, electrophoresis → packaging.

[0003] like Figure 1 、 Figure 2 、 Figure 3 As shown, Figure 1 The single-layer core 1 of the rotor iron core includes a cylindrical body 101. The curved outer wall of the body 101 is circumferentially and equidistantly provided with a plurality of teeth 102 around the central axis of the body 101. The space between adjacent teeth 102 forms a slot 103. The number of teeth 102 and slots 103 is n. An axial hole 104 is provided at the center of the body 101. The central axis of the axial hole 104 coincides with the central axis of the body 101, and the axial hole 104 is a through hole extending through the upper and lower bottom surfaces of the body 101. Obviously, the structure of the single-layer core 1 is relatively complex and is typically formed using a multi-step stamping process rather than a single-step stamping process. The multi-step stamping process generally begins with a preliminary stamping to create a rough outline, and then gradually completes the processing of the detailed parts through subsequent stamping. In addition to ensuring the dimensional accuracy and quality of the single-layer core, the multi-step stamping process can also reduce problems such as material breakage and excessive deformation that can occur in single-layer cores made of thinner or high-strength materials during a single stamping process.

[0004] The multi-step process for stamping a single-layer chip 1 typically includes: cutting a portion of a silicon steel coil (also known as a sheet) or punching it into a disc on a first punch press; transferring the disc to a second punch press to punch an axial hole 104 to obtain a semi-finished product; and transferring the semi-finished product to a third punch press to punch a slot 103 to obtain a single-layer chip 1. In actual operation, the axial hole 104 and the slot 103 can also be punched simultaneously on the same punch press.

[0005] It can be seen that the above production process requires the use of multiple punching machines and multiple transfers, which is inefficient. In actual production, many manufacturers have their staff manually remove the single-layer chip 1 and replace it with a new wafer in accordance with the working frequency of the punching machine. This operation has a very large safety hazard and is relatively dangerous.

[0006] Therefore, the existing motor core production device has the problems of low efficiency and low safety. Summary of the Invention

An L-shaped rod 903 is vertically installed on the top of the fixed plate; a second cylinder 904 is vertically fixedly installed on the top of the shell 208, and a slider 905 that can slide up and down is slidably installed in the second cylinder 904, and the bottom of the slider 905 is fixedly connected to the top of the telescopic end of the fourth telescopic member 901, and the top of the slider 905 is fixedly connected to the bottom of the end of the L-shaped rod 903 away from the adsorption member 902. The outer surface of the slider 905 is provided with two axially symmetrical protrusions, and two arc grooves 9041 for the two protrusions to slide respectively are provided on the inner wall of the second cylinder 904. The arc groove 9041 includes, from top to bottom, a first vertical section, an arc section that can make the protrusion rotate 180° when rising and reverse 180° when descending, and a second vertical section.

[0028] The working principle of the present invention is as follows: when the complete portion of the sheet reaches the initial workstation 301, both the winder and the unwinder are suspended, allowing the sheet to remain at its current position. While the telescopic end of the first telescopic member 207 shortens and drives the notching punches 701 to notch the semi-finished product, the telescopic end of the second telescopic member 403 extends, driving the lifting platform 402 to descend. The large cylinder 4011 and the large annular flange 4012 descend as the lifting platform 402 descends. After the large annular flange 4012 contacts the sheet, it cooperates with the punching die ring 6018 to punch the sheet to separate a single disc from the sheet. The disc falls into the die 601, and a notch appears on the sheet. The portion of the side of the punching die ring 6018 located between the top of each special-shaped plate 6015 and the top of the second cylinder 6014 acts as a barrier, both limiting the position of the disc and protecting it. The telescopic end of the second telescopic member 403 rests on the current position and remains motionless, and the large annular flange 4012 keeps pressing the state of the disc, plays the effect of fixing the disc.At this moment, the telescopic end of the third telescopic member 502 extends, drives small cylinder 5011 and small annular flange 5012 to descend, and small annular flange 5012 cooperates with the punching die hole 6017 on the die 601 to punch out the axial hole 104 at the center of the disc, and the waste material that is flushed out can fall to the outside of the die 601 after the inside of the second cylinder 6014, frustum 6013, small base plate 6012, axle body 6011 along the punching die hole 6017 successively.After punching is completed, the telescopic end of the third telescopic member 502 shortens, drives small cylinder 5011 and small annular flange 5012 to rise. After the punching of the shaft hole 104 is completed, the telescopic end of the second telescopic member 403 shortens, driving the lifting platform 402 to rise. The large column 4011 and the large annular flange 4012 rise along with the lifting platform 402. The unwinder continues to unwind and the winder continues to wind, causing the sheet to move from the feed end to the discharge end of the conveyor table 3. When the chipped portion of the sheet, i.e., the waste material, leaves the initial station 301 and the new intact portion arrives at the initial station 301, both the winder and the unwinder pause.

[0029] While punching the edges and holes, it is necessary to punch out the grooves 103 on the semi-finished product in the die 601 of each notching station. The telescopic end of the first telescopic member 207 shortens, driving the upper disc 206 to descend, thereby driving the first cylinders 702 in the N notching assemblies 7 to descend together. After the stamping is completed, the telescopic end of the first telescopic member 207 extends, driving the upper disc 206 to rise, thereby driving the first cylinders 702 of the N notching assemblies 7 to rise together. When the first cylinder 702 descends, when the pressing block 703 does not contact the semi-finished product in the die 601, the return spring 704 is in a naturally extended state, and the pressing block 703 descends with the first cylinder 702. When the bottom of the pressing block 703 contacts the top of the semi-finished product, the pressing block 703 no longer moves, but the first cylinder 702 continues to descend. The return spring 704 is gradually compressed, and the double-headed capped rod 705 descends with the first cylinder 702. The rod body of the cap rod 705 slides downward in the upper cavity 7032, the cap body slides downward in the lower cavity 7033, and the k notching punches 701 also slide downward in the through groove 7031. After contacting the top of the semi-finished product, they cooperate with the die 601 to punch out k grooves 103 on the semi-finished product during the descending process. When the cap body contacts the bottom of the lower cavity 7033, the k notching punches 701 have dropped to the lowest point and have cooperated with the notching die hole 6016 on the die 601 to complete the notching. After the waste falls into the notching die hole 6016, it descends along the side of the truncated cone 6013 while moving away from the second cylinder 6014, and finally falls outside the die 601. When the first cylinder 702 rises, it drives the rod body of the double-headed capped rod 705 to slide upward in the upper cavity 7032, the cap body slides upward in the lower cavity 7033, and the k notching punches 701 also slide upward in the through slot 7031. The return spring 704 gradually extends. When the cap body contacts the top of the lower cavity 7033, the clamping block 703 begins to rise with the rise of the first cylinder 702 until it returns to its initial height.

[0030] After completing the punching, hole punching, and notching operations, the second motor 801 is started. The output shaft of the second motor 801 drives the pinion 802 to rotate. The pinion 802 drives the inner ring gear 804 to rotate through the large gear 803. The inner ring gear 804 drives the rotating table 203 to reverse through the small cylinder 2032. Each die 601 rotates to the next adjacent station in the counterclockwise direction along with the rotating table 203. For example, the die 601 at the initial station 301 rotates to the first notching station 302, the die 601 at the sixth notching station 307 rotates to the blanking station 308, and the die 601 at the blanking station 308, from which the single-layer chip 1 has been removed, rotates back to the initial station 301. When the die 601 rotates from the current station to the next station, the first motor 605 starts, driving the first pulley 606 to rotate, and the first pulley 606 drives the second pulley 607 to rotate through the belt 608, thereby driving the die 601 to rotate. The die 601 and the semi-finished product in the die 601 rotate to a position that matches the angle and position of the k notching punches 701 of the current station, so as to accurately punch the notches at the expected positions.

[0031] Initially, the telescopic end of the fourth telescopic member 901 is in an extended state, and the suction member 902 is at the highest point of its travel and above the collection box. When the die 601 containing the single-layer chip 1 rotates to the unloading station 308 and stays at the unloading station 308, the telescopic end of the fourth telescopic member 901 begins to shorten, and the protrusion first slides vertically downward for a short distance in the first vertical section, then enters the arc section, descends and reverses 180°, driving the suction member 902 to descend and reverse 180° to reach the top of the die 601, then enters the second vertical section and slides vertically downward for a short distance, causing the suction member 902 to reach the lowest point of its travel, and the n negative pressure suction cups respectively contact the tops of the n teeth 102 of the single-layer chip 1, the negative pressure pump is in a stopped state, and the pressure in each negative pressure suction cup is equal to the external atmospheric pressure. When it is necessary to adsorb a single-layer chip 1, the negative pressure pump is started. The negative pressure generated by the negative pressure pump is transmitted to each negative pressure suction cup through the distributor and the hose, quickly extracting the air in each negative pressure suction cup. The n negative pressure suction cups respectively adsorb the n teeth 102 of the single-layer chip 1. The adsorption member 902 adsorbs the single-layer chip 1, and the negative pressure suction cup maintains the adsorption state. The telescopic end of the fourth telescopic member 901 begins to extend, and the protrusion first slides vertically upward for a short distance in the second vertical section, causing the adsorption member 902 to move upward and carry the single-layer chip 1 away from the die 601, and then enter the arc section, while rising and rotating 180° forward, driving the adsorption member 902 to rise and rotate 180° forward and return to the top of the collection box, and then slide vertically upward for a short distance in the first vertical section, so that the adsorption member 902 reaches the highest point of its stroke, and then stops the negative pressure pump to release the adsorption state of the negative pressure suction cup, and the single-layer chip falls into the collection box (which can also be a conveyor belt, etc., according to user needs).
