The electric push rod 7 is fixedly installed in the turntable 35, and the outer wall of the electric push rod 7 is fixedly connected to a push block 8. A second groove 13 is provided in the turntable 35, and the second groove 13 is movably sleeved on the outer wall of the push block 8; a third spring 38 is fixedly installed in the upper mold base 18, and the outer wall of the third spring 38 is fixedly connected to a moving column 39, and the upper mold base 18 is movably sleeved on the outer wall of the moving column 39, and the outer wall of the moving column 39 is movably sleeved with a lower mold base 37, and the lower mold base 37 is fixed in the lower mold base 37.

[0048] Furthermore, during the forming process of metal parts, the staff determines the corresponding mold according to the metal parts to be processed. There are four specifications of upper mold seats 18 on the same turntable 35. The staff determines the position of the required upper mold seat 18 on the turntable 35 according to the required mold, and then starts the first motor 3. The first motor 3 drives the first rotating shaft 4 to rotate, and the first rotating shaft 4 drives the four movable shafts 15 to rotate, and controls the electric push rod 7 in one of the turntables 35 to start. The electric push rod 7 drives the push block 8 to move in the second groove 13, so that the push block 8 no longer closes the second groove 13. During the rotation process of the movable shaft 15 in contact with this turntable 35, the movable shaft 15 drives the internal first spring 11 and the positioning column 9 to rotate. When the positioning column 9 moves to the position of the second groove 13, the first spring 11 elastically pushes the positioning column 9. The positioning column 9 moves in the first groove 10, so that part of the positioning column 9 moves out of the first groove 10 and enters the second groove 13, so that the positioning column 9 in the movable shaft 15 is inserted into the turntable 35, the movable shaft 15 drives the positioning column 9 to rotate, the positioning column 9 drives the turntable 35 to rotate, and the turntable 35 drives the mounting seat 17 and the upper mold seat 18 to rotate. When the required upper mold seat 18 moves to the bottom of the turntable 35, the staff starts the electric push rod 7 again, so that the electric push rod 7 drives the push block 8 to close the second groove 13, and the push block 8 drives the positioning column 9 to move out of the second groove 13, so that the positioning column 9 is no longer inserted into the turntable 35, so that the movable shaft 15 and the positioning column 9 no longer drive the turntable 35, thereby completing the adjustment of the upper mold seat 18 on one turntable 35, and continuing through the above steps, the upper mold seat 18 of other turntables 35 can be adjusted;

[0049] After the adjustment of the upper die seat 18 is completed, the first motor 3 is turned off and the hydraulic rod 34 is started. The hydraulic rod 34 drives the connecting plate 5 to move downward, the connecting plate 5 drives the first connecting rod 6 and the second connecting rod 12 to move downward, the first connecting rod 6 and the second connecting rod 12 drive the mounting block 2 and the fixed shaft 14 to move, the mounting block 2 and the fixed shaft 14 drive the turntable 35 to move, the turntable 35 drives the upper die seat 18 to move downward, so that the lower die seat 37 below the upper die seat 18 moves into the second opening groove 49, and the fixing column 50 in the second opening groove 49 is inserted into the lower die seat 18. The first opening groove 40 in the die base 37, the fixed column 50 pushes the movable column 39 upward, the movable column 39 squeezes the trapezoidal block 51, and the inclined surface of the third opening groove 55 on the movable column 39 contacts the inclined surface of the trapezoidal block 51, so that the movable column 39 drives the trapezoidal block 51 to compress the fifth spring 69, and the trapezoidal block 51 gradually moves out of the third opening groove 55, so that the trapezoidal block 51 gradually releases the engagement with the movable column 39. After the trapezoidal block 51 no longer engages with the movable column 39, the upper die base 18 and the lower die base 37 are separated, so that the required lower die base 37 is moved to the base 1;

[0050] The turntable 35 is adjusted in sequence to move the required upper die base 18 on the turntable 35 to the position below the turntable 35 to complete the mold switching of the device, and then the upper die base 18 is separated from the lower die base 37, and the lower die base 37 is placed on the base 1, so that the device can simultaneously process metal parts of different specifications or simultaneously process multiple metal parts of the same specification, thereby improving the processing efficiency of the device and improving the flexibility of the device.

[0052] Furthermore, the staff determines the required upper die seat 18 and the position of the required upper die seat 18 on the turntable 35 according to the metal parts to be processed, and then starts the third motor 27 at the corresponding position of the upper die seat 18, that is, the two third motors 27 closest to the required upper die seat 18, and the third motor 27 drives the third rotating shaft 28 to rotate, and the third rotating shaft 28 drives the pressing block 29 to move, so that the two pressing blocks 29 are gradually separated, and then the pressing block 29 is no longer in contact with the inclined surface of the positioning block 30, so that the pressing block 29 no longer drives the positioning block 30 to compress the second spring 31. At this time, the third motor 27 drives the third rotating shaft 28 to rotate, and the third rotating shaft 28 drives the pressing block 29 to move. The second spring 31 recovers from the compressed state, and the second spring 31 drives the positioning block 30 to move, so that the positioning block 30 contacts the annular block 16, and then the first motor 3 is started, and the first motor 3 drives the first rotating shaft 4 and the movable shaft 15 to rotate, and the electric push rod 7 is started, and the electric push rod 7 drives the pushing block 8 to no longer close the second groove 13, and the movable shaft 15 drives the first spring 11 and the positioning column 9 to rotate.

When the required upper die seat 18 moves to the bottom of the rotating disk 35, the positioning block 30 moves to the positioning groove 26 at the bottom of the annular block 16.

The positioning block 30 is inserted into the annular block 16 so that the annular block 16 is aligned with the positioning groove 26. The block 30 is fixed, and the positioning block 30 fixes the turntable 35 to prevent the turntable 35 from continuing to rotate. After the staff observes that the turntable 35 stops, the electric push rod 7 is started again, so that the electric push rod 7 drives the pushing block 8 to close the second groove 13, so that the movable shaft 15 and the positioning column 9 no longer drive the turntable 35, and the adjustment of the turntable 35 is completed.
