This silicon steel sheet stamping device employs a novel structural design, enabling stable clamping of the stamped parts, automatic demolding, and assistance for worker unloading, resulting in a high degree of automation.

[0004] The aforementioned silicon steel sheets can achieve automatic demolding during the stamping process. However, both the aforementioned silicon steel sheets and traditional silicon steel sheets are stamped in the middle of the steel sheet. The spacing between the middle of multiple consecutive stampings is too large, resulting in a large amount of steel sheet waste. To address this, we designed a continuous material-saving stamping device for silicon steel sheets with an electric motor rotor. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous material-saving stamping device for silicon steel sheets of electric motor rotors, so as to solve the problems mentioned in the background art.

[0009] In the above-mentioned continuous material-saving stamping device for silicon steel sheets of electric motor rotor, the top block has a cavity inside, and the tops of multiple connecting rods are inserted into the cavity and fixedly connected to mounting blocks.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-5 As shown, the present invention relates to a continuous material-saving stamping device for silicon steel sheets of electric motor rotor, comprising a base 1, with supporting columns 2 fixedly installed at the four corners of the top of the base 1, top blocks 3 fixedly installed at the top of the four supporting columns 2, and multiple lower stamping seats 4 staggeredly distributed and fixedly installed in the middle of the top of the base 1, with multiple telescopic connecting rods 5 staggeredly arranged at the bottom of the top blocks 3, and upper stamping blocks 6 fixedly installed at the bottom of the multiple connecting rods 5.

[0023] Specifically, by replacing the traditional straight design with an interlaced design of the lower stamping seat 4, the edges of the steel sheet can be effectively utilized during the stamping process, achieving a better material-saving effect during continuous stamping.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention relates to a continuous material-saving stamping device for silicon steel sheets of electric motor rotor. The base 1 has a waste collection cavity 12 at the bottom, which is an inverted truncated pyramid structure. A pressing groove 15 is provided at the center of the bottom end of the waste collection cavity 12. An electric hydraulic cylinder 13 is fixedly installed at the top of the waste collection cavity 12. A pressing block 14 is fixedly installed at the telescopic end of the electric hydraulic cylinder 13. The pressing block 14 is aligned with the pressing groove 15. A waste outlet 8 communicating with the outside is provided on one side wall of the pressing groove 15. An installation groove 17 is provided in the middle of the other side wall of the pressing groove 15. A push plate 16 is nested inside the installation groove 17. An electric push rod 18 is fixedly installed at the bottom of the installation groove 17. The telescopic end of the electric push rod 18 is fixedly connected to the center of the side of the push plate 16.

[0025] Specifically, the electric hydraulic cylinder 13 pushes the pressing block 14 downward. Since the pressing block 14 is compatible with the pressing trough 15, it can press the waste collected inside the pressing trough 15 into blocks. After the blocks are pressed, the electric push rod 18 pushes the push plate 16 to move. The push plate 16 pushes the blocky waste out of the waste outlet 8, completing the waste processing and recycling. It should be noted that the size of the waste outlet 8 is larger than the size of the pressing trough 15 to avoid the problem of blocky waste blocking the waste outlet 8.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention relates to a continuous material-saving stamping device for silicon steel sheets of electric motor rotor. The top block 3 has a cavity 9 inside. The tops of multiple connecting rods 5 are inserted into the cavity 9 and are fixedly connected to mounting blocks 11. Multiple electric cylinders 10 are fixedly installed at equal intervals at the top of the cavity 9. The telescopic ends of the electric cylinders 10 are fixedly connected to the top of the mounting blocks 11.

[0027] Specifically, the electric cylinder 10 pushes the connecting rod 5 to rise and fall, and the connecting rod 5 drives the upper stamping block 6 to rise and fall, so that the upper stamping block 6 and the lower stamping seat 4 can be closed and stamped.

[0028] The air inlet of multiple electric cylinders 10 is fixedly connected to an external air pump, and an alarm light 7 is fixedly installed on the top of the top block 3.

[0029] Specifically, by setting alarm light 7, an alarm can be triggered when a problem occurs during the stamping process.

[0030] A programmable PLC controller is fixedly installed on the front of the base 1. The electric cylinder 10, electric hydraulic cylinder 13, electric push rod 18 and alarm light 7 are all electrically connected to an external power supply through the programmable PLC controller.

[0031] In specific implementation, during the continuous material-saving stamping process, when the material enters the interior of the base 1, the electric cylinder 10 is opened, and the electric cylinder 10 pushes the connecting rod 5 downward. The downward movement of the connecting rod 5 causes the upper stamping block 6 and the lower stamping seat 4 to close, thereby realizing the stamping of the silicon steel sheet. The lower stamping seats 4 are staggered, replacing the traditional linear design. During stamping, the edges of the steel sheet can be effectively utilized, and a better material-saving effect is achieved in the continuous stamping process.

[0032] The waste generated during stamping falls into the waste collection chamber 12. The waste inside the waste collection chamber 12 flows into the pressure groove 15. Then, the electric hydraulic cylinder 13 is opened, and the pressure block 14 is pushed down by the electric hydraulic cylinder 13 to press the waste into blocks. After the blocks are pressed, the electric push rod 18 is opened, and the push plate 16 is pushed to move by the electric push rod 18. The formed block waste is pushed out from the waste outlet 8 by the push plate 16.

[0033] It should be noted that the PLC controller, electric cylinder 10, electric hydraulic cylinder 13, electric push rod 18 and alarm light 7 are all commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0034] Contents not described in detail herein are existing technologies known to those skilled in the art. The specific embodiments described herein are merely illustrative examples illustrating the spirit of this invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.
