DETAILED DESCRIPTION

[0042] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

The outlet of the three-way diverter 6 is connected to the inlet of the nozzle unit via a hose; the inlet of the three-way diverter 6 is connected to an inlet pipe 7, which passes through the fixed cylinder seat 5; the inlet pipe 7 is connected to a storage box, which stores a release agent solution; the hydraulic press 1 drives the forming mold 2 to close and open the mold, forging the high-temperature billet to obtain a magnesium alloy wheel hub; after the magnesium alloy wheel hub is forged in the forming mold 2, the surface of the magnesium alloy wheel hub is prone to sticking to the inner wall of the forming cavity of the forming mold 2. When the demolding mechanism on the forming mold 2 pushes out the magnesium alloy wheel hub, and when the wheel hub clamp 4 removes the magnesium alloy wheel hub, it is easy to cause surface defects on the magnesium alloy wheel hub. Scratches and tears may occur; therefore, before the high-temperature blank is transferred to the forming mold 2, the hydraulic press 1 drives the forming mold 2 to the open state, and the steering mechanism adjusts the direction so that the spraying mechanism is close to the hydraulic press 1. At the same time, the robotic arm 3 accurately moves the fixed cylinder seat 5 between the upper and lower molds of the forming mold 2. The pumping mechanism on the storage tank sends the stored release agent solution into the three-way distributor 6 through the water inlet pipe 7, and then the spray unit sprays the release agent solution onto the mating surfaces of the upper and lower molds of the forming mold 2, so that the release agent solution covers the inner wall of the forming cavity of the forming mold 2, forming a uniform release film on the inner wall of the forming cavity of the forming mold 2. After that, the steering mechanism turns The spraying mechanism is moved out of the hydraulic press 1, and the high-temperature billet is transferred to the forming mold 2 for forging. Then, the hydraulic press 1 drives the forming mold 2 to open the mold. The demolding mechanism on the forming mold 2 pushes out the magnesium alloy wheel hub. At the same time, the steering mechanism rotates so that the wheel hub gripper 4 faces the hydraulic press 1. With the cooperation of the robotic arm 3, the wheel hub gripper 4 clamps and removes the magnesium alloy wheel hub. Since there is a release film between the magnesium alloy wheel hub and the forming cavity of the forming mold 2, the adhesion between the magnesium alloy wheel hub and the forming cavity of the forming mold 2 is reduced, and the surface of the magnesium alloy wheel hub is reduced to avoid scratches and scratches. This improves the processing quality of the magnesium alloy wheel hub and increases the production efficiency of the magnesium alloy wheel hub.

[0056] S8: At this time, the high-temperature blank is transferred to the forming die 2 for forging forming to obtain a new magnesium alloy wheel hub;

[0057] S9: Finally, the magnesium alloy wheel hub is machined and coated, and after quality inspection, it is stored in the warehouse.

[0058] Working principle: magnesium alloy bars are used as raw materials, the magnesium alloy bars are cut into appropriate sizes to obtain original blanks; the original blanks are transferred to a heating furnace for heating treatment to obtain high-temperature blanks;

[0059] Before the high-temperature blank is transferred to the forming die 2, at this time, the hydraulic machine 1 drives the forming die 2 to be in an open mold state, the motor 9 drives the cross beam 10 to rotate, so that the spraying mechanism is close to the hydraulic machine 1, the electric push rod 13 pushes the U-shaped extension frame 12 to slide and extend, and cooperates with the mechanical arm 3 to accurately move the fixed cylinder seat 5 between the upper mold and the lower mold of the forming die 2; the multi-stage telescopic rod 16 pushes the folding telescopic sleeve 15 to expand, and the annular gasket on the folding telescopic sleeve 15 contacts the upper mold and the lower mold of the forming die 2, thereby forming a relatively sealed environment between the upper mold and the lower mold of the forming die 2;

[0060] The pumping mechanism on the storage tank sends the stored release agent solution through the water inlet pipe 7 into the three-way distributor 6, the release agent solution is sent into the inner cavity 18 inside the spray head body 17, after passing through the impeller 20, the release agent solution enters the water cavity of the nozzle 19 through the water inlet hole of the nozzle 19, and is sprayed out through the water outlet hole of the nozzle 19, and when the release agent solution passes through the impeller 20, the impeller 20 is rotated to drive the nozzle 19 to rotate, thereby forming multiple rotating multi-angle release agent solution spray water columns, which can effectively cover the forming cavity of the forming mold 2; at the same time, the release agent solution in the inner cavity 18 is shunted into the annular water cavity 24, the air pump sends high-pressure airflow into the three-way air pipe 23, the high-pressure airflow enters the annular air distribution pipe 22, and then enters the annular air cavity 21, the high-pressure airflow enters the atomizing nozzle 25 through the air outlet hole 26, a negative pressure is formed near the air outlet hole 26 of the atomizing nozzle 25, so that the release agent solution in the annular water cavity 24 enters the atomizing nozzle 25 and mixes with the high-pressure airflow to form high-density release agent water mist, which is then limited by the annular groove and gathered at the forming cavity of the forming mold 2, the release agent water mist fills the gaps between the sprayed release agent solutions, and the release agent solution covers the inner wall of the forming cavity of the forming mold 2 to form a uniform release film on the inner wall of the forming cavity of the forming mold 2;

[0061] At the same time, the release agent solution sprayed on the upper mold forming cavity of the forming mold 2 will drip downward under the influence of gravity, and the dripping release agent solution falls on the upper baffle 14, and due to the annular inclined groove 27 on the baffle 14, the dripping release agent solution is gathered into the annular storage cavity 28 through the connecting port 29, the high-pressure airflow in the annular air distribution pipe 22 is shunted into the annular air groove 30, the high-pressure airflow enters the annular storage cavity 28 through the groove port 31, the high-pressure airflow is guided by the air guide strips 32 on both sides and then sprayed out from the connecting port 29, and when the high-pressure airflow passes through the annular storage cavity 28, the release agent solution in the annular storage cavity 28 is brought out to form water mist, thereby improving the utilization rate of the release agent solution;

[0062] Then, the turning mechanism moves the spraying mechanism out of the hydraulic machine 1, the high-temperature blank is transferred to the forming mold 2 for forging forming; then, the hydraulic machine 1 drives the forming mold 2 to open, the release mechanism on the forming mold 2 ejects the magnesium alloy hub, and the turning mechanism rotates to make the hub clamping jaw 4 face the hydraulic machine 1, cooperates with the mechanical arm 3, the hub clamping jaw 4 clamps and takes out the magnesium alloy hub, and then performs machining processing, the surface is coated, and after quality inspection, it is stored in the warehouse; since there is a release film between the magnesium alloy hub and the forming cavity of the forming mold 2, the adhesion between the magnesium alloy hub and the forming cavity of the forming mold 2 is reduced, the scratches and scratches on the surface of the magnesium alloy hub are reduced, thereby improving the processing quality of the magnesium alloy hub and improving the production efficiency of the magnesium alloy hub.

[0063] The foregoing merely illustrates the principles of the application and application of its more prominent features. Those skilled in the art will appreciate that the application is not limited to the embodiments described and illustrated and that many changes and modifications will occur to them without departing from the spirit and scope of the present application. The present application is therefore not to be limited to the exact details shown and described but only by the scope of the appended claims.
