The rotating shaft of the motor is penetratingly and rotatably arranged on the front surface of the triangular sliding plate 91. The belt rotating module is fixed to the front surface of the rotating shaft of the motor. The rotating shaft of the motor in the driving module three 92 drives the belt rotating module to reverse, the fan lever 93 is rotatably arranged on the inner wall of the triangular sliding plate 91. The plurality of fan blades of the fan lever 93 are arranged above the material guiding plate of the triangular sliding plate 91. The side of the belt rotating module away from the rotating shaft of the motor is fixed to the front surface of the rotating shaft of the fan lever 93. The belt rotating module drives the fan lever 93 to reverse, so that the fan blades on the fan lever 93 guide the formed gear out of the equipment, thereby avoiding the blockage of the discharging of the gear profiling equipment and causing the discharging to be inconvenient.

[0040] The material guiding device 9 also includes several semi-arc strip shells 94, several semi-arc spring pieces 95, and several rubber strips 96. The semi-arc strip shells 94 are respectively fixed to the top left side of the fan rod 93. The fan blades of the fan rod 93 drive the semi-arc strip shells 94 to rotate in reverse. A groove is opened in the middle of the left side of the semi-arc strip shells 94. The semi-arc spring pieces 95 are respectively fixed to the left side of the inner wall of the semi-arc strip shells 94. The semi-arc strip shells 94 drive the semi-arc spring pieces 95 to rotate in reverse. The rubber strips 96 are respectively fixed to the left side of the semi-arc spring pieces 95. The semi-arc spring pieces 95 drive the rubber strips 96 to rotate in reverse. The rubber strips 96 are slidably installed on the inner wall of the groove of the semi-arc strip shells 94. When the rubber strips 96 come into contact with the formed gear, under the elastic force of the semi-arc spring pieces 95, the semi-arc spring pieces 95 buffer the rubber strips 96, and the rubber strips 96 buffer the formed gear, so that the rubber strips 96 lightly touch the formed gear and push it, thereby avoiding scratches caused by the material output of the gear forming equipment, which would lead to a decrease in product quality.

[0041] Simultaneously with the activation of the powder injection device 6, the operator starts the drive module 2 71 via an electrical wire. The servo motor shaft in the drive module 2 71 begins to rotate reciprocally in both directions. The servo motor shaft drives the roller to rotate reciprocally left and right. Under the action of friction, the roller moves reciprocally left and right in the sliding groove of the U-shaped channel plate. The roller drives the servo motor to move reciprocally left and right. The servo motor slides reciprocally left and right in the U-shaped channel plate. The L-shaped support plate of the servo motor drives the flat shell 72 to move reciprocally left and right. At the same time, the powder suction pump 74 is started via an electrical wire. The powder suction pump 74 begins to suck air. The hose of the powder suction pump 74 sucks air in the flat shell 72. The flat shell 72 reciprocates left and right to suck up the metal powder on the equipment. The flat shell 72 absorbs the powder into the powder suction pump 74. The powder suction pump 74 discharges the powder into the powder storage box 73, so that the flat shell 72 evenly sucks up the metal powder on the concave block of the lifting module 2. This ensures that scattered metal powder is evenly recovered, preventing incomplete recovery and avoiding the problem of uneven metal powder collection and poor recovery effect caused by gear pressing equipment. While the L-shaped support plate of the servo motor drives the flat shell 72 to move back and forth, the strip filter plate 75 supports the horizontal plate 76. The flat shell 72 drives the cylinder 77 to move back and forth, and the cylinder 77 moves back and forth in the groove of the horizontal plate 76. During this process, the cylinder 77 impacts the groove of the horizontal plate 76, causing the horizontal plate 76 to vibrate. The horizontal plate 76 then drives the strip filter plate 75 to vibrate, causing larger metal powder particles to be dislodged and preventing them from clogging the strip filter plate 75. This avoids the problem of clogging caused by larger metal powder particles in the gear pressing equipment.

[0042] When the L-shaped support plate of the servo motor drives the flat shell 72 to move back and forth, the flat shell 72 drives the long rod 81 to move back and forth, the long rod 81 drives the ring plate 82 to move back and forth, and the ring plate 82 drives the double-face chamfer block 83 to move back and forth, so that the double-face chamfer block 83 scrapes off the metal powder adhered to the concave block of the lifting die set 2, preventing the metal powder from adhering to the equipment, thereby avoiding the problem that the metal powder adhered to the gear profiling equipment causes inconvenience in recycling. When the flat shell 72 drives the long rod 81 to move back and forth, the long rod 81 drives the ring block 84 to move back and forth, the ring block 84 drives the Z-shaped plate 85 to move back and forth, the Z-shaped plate 85 drives the arc-shaped scraper one 86 to move back and forth, the arc-shaped scraper one 86 moves back and forth in the U-shaped groove plate sliding groove of the driving die set two 71, the ring block 84 drives the arc-shaped scraper two 87 to move back and forth, and the arc-shaped scraper two 87 moves back and forth in the sliding groove of the horizontal plate 76, so that the arc-shaped scraper one 86 and the arc-shaped scraper two 87 scrape off the metal dust in the sliding groove, preventing the metal dust from accumulating in the sliding groove of the equipment, thereby avoiding the problem that the metal dust accumulated in the sliding groove of the gear profiling equipment causes the equipment to be stuck.

[0043] When the rubber pad 68 drives the just-formed gear to slide to the right, the formed gear moves to the right on the triangular sliding plate 91, and the driving die set three 92 is started by a wire, the motor shaft in the driving die set three 92 starts to reverse, the belt rotating die set is driven to reverse by the motor shaft, the fan lever 93 is driven to reverse by the belt rotating die set, so that the fan blades on the fan lever 93 guide the formed gear out of the equipment, preventing the gear blanking from being blocked, thereby avoiding the problem that the gear profiling equipment causes the discharge to be blocked, causing the discharge to be inconvenient. When the belt rotating die set drives the fan lever 93 to reverse, the fan blades of the fan lever 93 drive the semi-arc strip shell 94 to reverse, the semi-arc spring piece 95 is driven to reverse by the semi-arc strip shell 94, the rubber strip 96 is driven to reverse by the semi-arc spring piece 95, and the rubber strip 96 contacts the formed gear. Under the action of the elastic force of the semi-arc spring piece 95, the semi-arc spring piece 95 buffers the rubber strip 96, and the rubber strip 96 buffers the formed gear, so that the rubber strip 96 lightly touches the formed gear to push it, preventing scratches from being generated on the surface of the formed gear, thereby avoiding the problem that the gear profiling equipment causes scratches during discharging, leading to a decrease in product quality.

Any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
