The specific implementation process is as follows:

after one end of a rod-shaped part 25 to be processed is heated, the heated end of the part 25 faces upwards, the other end of the part faces downwards and is sequentially inserted into the through hole 11 and the insertion hole 8, the through hole 11 and the insertion hole 8 are used for limiting and fixing the two ends of the part 25 respectively, the part 25 is prevented from being inclined, the forming quality of the air valve is guaranteed, and after the part 25 is placed, the heated part of the part 25 is located in the extrusion groove 5. And there is a gap between the face of the part 25 and the wall of the bore 11.

And starting the air cylinder, wherein the air cylinder pushes the extrusion head 3 to slide downwards on the base 1 to be close to the fixed seat 2. The water valve on the water inlet pipe 14 is opened, but when the extrusion head 3 slides downwards, the push rod 19 pushes the piston 18 to slide downwards in the airflow pipe 17, so that the pressure in the airflow pipe 17 is increased, and the blocking ball 16 is pushed into the water inlet pipe 14 under the action of the pressure to block the water inlet pipe 14, so that the water inlet pipe 14 cannot enter the extrusion groove 5 at the moment. The dead lever 20 leads the motion of stifled ball 16, carries on spacingly to stifled ball 16 simultaneously, prevents that stifled ball 16 from receiving the impact of water and taking place the skew, guarantees the shutoff effect of stifled ball 16 to inlet tube 14.

When extrusion head 3 moved down, rack 21 followed extrusion head 3 and moved down, rack 21 promoted the meshing gear 22 rotatory, gear 22 drives the fan 24 rotation that the belt is connected, and the air current in bellows 23 flows fast under fan 24's effect and enters into in aerifing interlayer 9 via gas tube 10, aerifys interlayer 9 this moment and aerifys and expand to the center of jack 8 to hold the lower extreme of part 25 tightly fixedly, keep the stability of part 25, and then guarantee the extrusion effect of part 25. In order to ensure the inflation effect of the inflatable interlayer 9, a negative pressure fan is connected to the inflation tube 10 and is used for sucking airflow into the inflatable interlayer 9.

After the extrusion forming of the air valve is completed, the air cylinder drives the extrusion head 3 to move upwards and far away from the fixed seat 2, at the moment, the extrusion head 3 drives the piston 18 to slide upwards in the airflow pipe 17 through the push rod 19, the air pressure in the airflow pipe 17 is reduced, the blocking ball 16 slides downwards under the action of gravity to fall back into the branch pipe 15 and block the branch pipe 15, and at the moment, the water inlet pipe 14 is opened and water enters the extrusion groove 5. The ball 16 seals off the branch pipe 15 from water entering the gas flow pipe 17.

After the water enters the extrusion groove 5, the water flow is sprayed on the flat part of the valve which is extruded and formed, and the flat part of the valve is cooled, so that the temperature of the valve is reduced, the valve is quickly hardened, and the forming effect of the valve is ensured. By adopting the cooling mode, the problem that cooling water splashes everywhere can be effectively avoided, and the neatness of the processing environment is kept.

At this moment, because the flat part of the valve after being extruded blocks the through hole 11, water can not flow into the water storage cavity 6 through the through hole 11, but enters the drain pipe 12 through the drain hole, and is sprayed out to the valve at the side through the water spraying hole 13 on the drain pipe 12, and the rod body part of the valve is cooled, so that the comprehensive cooling effect of the valve is ensured, and the subsequent collection and processing of the valve are facilitated.

After water enters the water storage cavity 6, the water leaks downwards along the hollowed-out part of the floating plate 7 and is deposited at the bottom of the water storage cavity 6, the liquid level in the water storage cavity 6 rises at the moment, the floating plate 7 floats upwards along the liquid level under the action of buoyancy, and the inflatable interlayer 9 is in an inflatable state at the moment and increases the buoyancy of the floating plate 7, so that the floating plate 7 can smoothly float. The floating plate 7 floats upwards and drives the air valve to move upwards, so that the air valve is separated from the water storage cavity 6, and the air valve after being processed and cooled is taken out conveniently. And in the process of moving the valve upwards, after the flat part of the valve is far away from the through hole 11, the gap between the through hole 11 and the rod body part of the valve is opened, part of water in the extrusion groove 5 flows downwards into the water storage cavity 6 through the gap, and in the flowing process, the rod body part of the valve is intensively cooled, so that the cooling effect on the valve is further enhanced.

When the floating plate 7 floats to the lower part of the fixed plate 4 and is abutted against the fixed plate 4, the floating plate 7 cannot move continuously, and the air valve is kept stable in the extrusion groove 5 at the moment so as to be convenient for an operator to take down the air valve.

After the air valve is taken down, the air release valve on the air release pipe connected with the inflatable interlayer 9 is opened, and the inflatable interlayer 9 is deflated to be used for forming and fixing the next batch of parts 25. At the same time, the valve on the liquid discharge pipe connected with the water storage cavity 6 is opened to discharge water to the water storage cavity 6, so that the floating plate 7 is sunk at the bottom of the water storage cavity 6 to be used for processing the next batch of parts 25.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
