DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] When implementing: Figure 1-4 As shown, the motor stator and rotor iron sheet shaping device comprises: a workbench 1, a groove 101 is opened on the top of the workbench 1, and a mounting frame 102 is arranged on the top of the workbench 1; a flip component 2, the flip component 2 is arranged on one side of the workbench 1; a shaping component 3, the shaping component 3 is arranged on the top of the mounting frame 102; wherein, the shaping component 3 comprises a second hydraulic push rod 301 arranged on the top of the mounting frame 102, the output shaft of the second hydraulic push rod 301 passes through the mounting frame 102 and is fixedly connected with a shaping block 302, a connecting cavity 306 is opened inside the shaping block 302, and an exhaust hole 307 which is distributed in an annular manner and communicated with the connecting cavity 306 is opened at the bottom of the shaping block 302, and the opening width of the groove 101 is smaller than the diameter of the motor stator and rotor iron sheet.

[0020] The motor stator and rotor iron core pieces to be shaped are placed above the workbench 1 and at the bottom of the shaping block 302. The shaping block 302 is driven downward by starting the second hydraulic push rod 301 so that the shaping block 302 squeezes and shapes the top surface of the motor stator and rotor iron core pieces.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the shaping component 3 also includes two connecting cylinders 303 fixedly connected to the top of the mounting frame 102 and symmetrically distributed, an adjusting plate is slidably connected inside the connecting cylinder 303, an adjusting rod 304 is fixedly connected to the bottom of the adjusting plate, the lower end of the adjusting rod 304 passes through the connecting cylinder 303 and the mounting frame 102 in sequence and is fixedly connected to the top of the shaping block 302, an adjusting cavity is formed between the bottom of the adjusting plate and the inner wall of the connecting cylinder 303, an air inlet pipe 309 connected to the adjusting cavity is provided on the surface of the connecting cylinder 303, a second one-way valve 310 is provided inside the air inlet pipe 309, two conduits 305 connected to the connecting cavity 306 are provided on the top of the shaping block 302, the other end of the conduit 305 is connected to the adjusting cavity, and a first one-way valve 308 is provided inside the conduit 305, a spring 311 is fixedly connected to the bottom of the adjusting plate, and the lower end of the spring 311 is fixedly connected to the inner wall of the connecting cylinder 303;

[0022] The first one-way valve 308 and the second one-way valve 310 are both relatively mature components in the prior art. The first one-way valve 308 can allow the air inside the regulating chamber to enter the inside of the conduit 305 in one direction, and the second one-way valve 310 can allow the outside air to enter the inside of the regulating chamber in one direction.

[0023] When the second hydraulic push rod 301 drives the shaping block 302 to move downward, the adjusting plate can be driven to move downward synchronously through the adjusting rod 304, thereby squeezing the air stored in the adjusting chamber, so that the internal air is injected into the connecting chamber 306 through the first one-way valve 308 and the conduit 305, and is discharged through the exhaust hole 307 under the action of the connecting chamber 306. In this process, the dust and impurities adhering to the surface of the shaping block 302 can be blown away to prevent the dust and impurities from affecting the shaping effect of the shaping block 302 on the iron chip;

[0024] After the shaping is completed, the second hydraulic push rod 301 drives the shaping block 302 to move up and reset. During this process, the spring 311 can assist the adjustment rod 304 and the adjustment plate in resetting. At the same time, due to the upward movement of the adjustment plate, the internal space of the adjustment chamber increases, so that low pressure is formed inside. The outside air is injected into the interior of the connecting tube 303 through the second one-way valve 310 and the air intake pipe 309 for reuse.

[0025] like Figure 1 and Figure 2As shown, the flip assembly 2 includes a connecting frame 201 fixedly connected to one side of the workbench 1, the cross-sectional shape of the connecting frame 201 is "L"-shaped, a connecting plate 202 is provided on one side of the connecting frame 201, a turntable 205 is provided on the side of the connecting plate 202 close to the workbench 1, and a driving motor 203 is provided on the other side of the connecting frame 201, and the output shaft of the driving motor 203 passes through the connecting frame 201 and the connecting plate 202 in sequence and is fixedly connected to one side of the turntable 205, and a mounting plate 206 is eccentrically fixedly connected to the surface of the turntable 205, the mounting plate 206 matches the groove 101, and an electromagnet 207 is embedded and installed on the surface of the mounting plate 206, and a first hydraulic push rod 204 is provided on the surface of the connecting frame 201, and the output shaft of the first hydraulic push rod 204 passes through the connecting frame 201 and is fixedly connected to the surface of the connecting plate 202.

[0026] After the shaping of one side of the iron chip is completed by the shaping component 3, the connecting plate 202 is driven to move toward the workbench 1 by the first hydraulic push rod 204. In this process, the mounting plate 206 can be driven to move above the shaped iron chip. At this time, the electromagnet 207 is started to make the electromagnet 207 adsorb the iron chip, and the mounting plate 206 is driven to reset by the first hydraulic push rod 204. After resetting, the turntable 205 can be driven to flip 180 degrees by starting the drive motor 203, so as to achieve the effect of driving the iron chip to flip 180 degrees, so that the unshaped side of the iron chip faces upward, and then the first hydraulic push rod 204 is started to drive the mounting plate 206 to move. This mounting plate 206 can be inserted into the inside of the groove 101. After moving into place, the electromagnet 207 is powered off and stops adsorbing the iron chip, and the first hydraulic push rod 204 drives the mounting plate 206 to reset again, so as to facilitate the shaping of the other side of the iron chip by the shaping component 3.

[0027] When the utility model is in use, the motor stator and rotor iron chips that need to be shaped are placed above the workbench 1 and at the bottom of the shaping block 302. The shaping block 302 is driven downward by starting the second hydraulic push rod 301, so that the shaping block 302 squeezes and shapes the top surface of the motor stator and rotor iron chips. In this process, the adjusting plate can be driven to move downward synchronously through the adjusting rod 304, thereby squeezing the air stored in the adjusting cavity, so that the internal air is injected into the connecting cavity 306 through the first one-way valve 308 and the conduit 305, and is discharged through the exhaust hole 307 under the action of the connecting cavity 306. In this process, the dust and impurities adhered to the surface of the shaping block 302 can be blown and cleaned to prevent the dust and impurities from affecting the shaping effect of the shaping block 302 on the iron chips. After the shaping of one side of the iron chips is completed by the shaping component 3, The first hydraulic push rod 204 drives the connecting plate 202 to move toward the workbench 1. During this process, it can drive the mounting plate 206 to move to the top of the iron chip after the shaping is completed. At this time, the electromagnet 207 is started to make the electromagnet 207 adsorb the iron chip, and the mounting plate 206 is driven to reset by the first hydraulic push rod 204. After resetting, the drive motor 203 is started to drive the turntable 205 to flip 180 degrees, so as to achieve the effect of driving the iron chip to flip 180 degrees, so that the unshaped side of the iron chip faces upward, and then the first hydraulic push rod 204 is started to drive the mounting plate 206 to move. This mounting plate 206 can be inserted into the inside of the groove 101. After moving into place, the electromagnet 207 is powered off and stops adsorbing the iron chip, and the first hydraulic push rod 204 drives the mounting plate 206 to reset again, so as to facilitate the shaping of the other side of the iron chip by the shaping component 3.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
