[0023] like Figure 2 As shown, four hydraulic telescopic rods 17 are fixedly connected to the lower surface of the top plate 1, and the output ends of the hydraulic telescopic rods 17 are fixedly connected to the upper surface of the partition 3.

[0024] like Figure 7As shown, the output end of the hydraulic telescopic rod 12 is slidably connected with a protective cover 1101, and the protective cover 1101 is fixedly connected to the upper surface of the upper mold frame 11.

Two cooling water pipes 804 are fixedly connected to the side of the water pump 803, and the other ends of the cooling water pipes 804 are connected to the surrounding pipeline opened inside the upper mold frame 11.

[0027] like Figure 4 As shown, an electric telescopic rod 14 is fixedly connected to the middle of the base 9. The electric telescopic rod 14 is three-stage telescopic. The output end of the electric telescopic rod 14 is provided with a spherical surface connected to the spherical surfaces of the two lower mold frames 10. When the two lower mold frames 10 are combined, they form a complete spherical surface with the output end of the electric telescopic rod 14.

[0028] Working principle: When the equipment is in use, the unloading mechanism 5 first delivers the heated sheet 16 into the equipment, and places it above the lower mold frame 10 and inside the four limit columns 901. The limit columns 901 limit the position of the sheet 16 to prevent the sheet 16 from moving during the stamping process. After the unloading mechanism 5 exits the equipment, the hydraulic telescopic rod 17 is started to push the partition 3 to move downward. The partition 3 moves downward to push the demoulding mechanism 6 to drive the two lower mold frames 10 to fit closely. The partition 3 moves downward to push the locking mechanism 7 to limit the position of the two lower mold frames 10 to prevent the lower mold frames 10 from retreating and shrinking when being stamped. Then the hydraulic telescopic rod 12 is started to push the upper mold frame 11 to move downward. The upper mold frame 11 Move downward to punch the plate 16 into an elliptical head 15. After the elliptical head 15 is stamped and formed, start the hydraulic telescopic rod 17 to pull the partition 3 upward. The partition 3 moves upward to pull the locking mechanism 7 to release the restriction on the two lower mold frames 10. The partition 3 moves upward to pull the demolding mechanism 6 to separate the two lower mold frames 10. Start the electric telescopic rod 14 to push the formed elliptical head 15 upward, and then start the unloading mechanism 5 to take out the stamped elliptical head 15, and place the plate 16 in the equipment for the next round of stamping. When the equipment is running, the cooling mechanism 8 cools the upper mold frame 11 to prevent the formed elliptical head 15 from being stuck on the upper mold frame 11, which makes demolding difficult.

[0029] After the equipment is started, the unloading mechanism 5 first sends the heated plate 16 into the equipment, and the electromagnetic frame 502 sucks up the heated plate 16, and the travel motor 505 is started. The output end of the travel motor 505 drives the travel gear 506 to rotate, and the travel gear 506 is meshed and connected with the travel rack 507. Under the action of the travel rack 507, the travel gear 506 rotates to drive the unloading body 512 to slide on the outside of the slide rail 503, and the unloading body 512 slides on the outside of the slide rail 503 to drive the steering shaft 511 to move toward the lower mold frame 10, and the steering shaft 511 moves to the lower mold frame 10 to drive the lifting frame 501 to move to the lower mold frame 10, and the lifting frame 501 moves to the lower mold frame 10 to drive the electromagnetic frame 502 to move to the lower mold frame 10. When the plate 16 moves to the top of the lower mold frame 10, the electromagnetic frame 502 is powered off, and the heated plate 16 falls to the top of the lower mold frame 10, reducing the direct contact between the staff and the heated plate 16 and preventing the staff from being scalded.

[0030] After the unloading mechanism 5 exits the equipment, the hydraulic telescopic rod 17 is started to push the partition 3 to move downward. When the partition 3 moves downward, it pushes the demoulding mechanism 6 to drive the two lower mold frames 10 to fit tightly together. The partition 3 moves downward and pushes the sliding seat 601 to move downward. The sliding seat 601 moves downward and pushes one end of the push rod 602 to move downward. Under the action of the middle limiting rod 605, the other end of the push rod 602 moves inward and drives the push seat 609 to move inward. The push seat 609 moves inward and drives the two lower mold frames 10 to move toward each other. The two lower mold frames 10 move toward each other and compress the tension spring 1001. At this time, the two lower mold frames 10 fit tightly together.

[0031] After the two lower mold frames 10 are tightly fitted, the partition 3 continues to move downward to push the locking mechanism 7 to limit the position of the two lower mold frames 10. The partition 3 continues to move downward, and the two sliding seats 601 slide to both sides to stretch the limit spring 603. After the partition 3 contacts the push trigger rod 701, the partition 3 and the push trigger rod 701 move downward, and the trigger rod 701 moves downward to push the trigger seat 702 to slide downward in the guide rail 703. The downward sliding of the trigger seat 702 drives one end of the linkage rod 704 to slide downward, and one end of the linkage rod 704 slides downward to push the other end of the linkage rod 704 to slide outward, and the other end of the linkage rod 704 slides outward to pull When the locking rod 705 is swung to the left, the locking rod 705 will slide forward, and the sliding of the locking rod 705 to the right will drive one end of the lifting rod 706 to slide in the elliptical through hole on the side of the locking rod 705. The sliding of the locking rod 705 to the right will stretch the return spring 708. At this time, the square groove on the upper surface of the locking rod 705 is misaligned with the T-shaped groove on the upper surface of the base 9. At this time, the T-shaped grooves of the two locking rods 705 are misaligned with the T-shaped blocks on the lower surface of the lower mold frame 10, limiting the lower mold frame 10 between the two locking rods 705, preventing the lower mold frame 10 from retreating during the stamping of the elliptical head 15, resulting in the stamping failure of the elliptical head 15, failing to meet product quality requirements, and increasing production costs.

[0032] After the elliptical head 15 is stamped, the hydraulic telescopic rod 17 is started to pull the partition 3 upward. When the partition 3 moves upward and pulls the locking mechanism 7 to release the restriction on the two lower mold frames 10, the partition 3 moves upward, the limit spring 603 contracts and pulls the two sliding seats 601 to slide inward, the partition 3 is out of contact with the trigger rod 701, the reset spring 708 resets and pulls the locking rod 705 to slide inwardly of the base 9, and the locking rod 705 slides inwardly to drive one end of the lifting rod 706 to the side of the locking rod 705 The locking rod 705 moves toward the inner side of the base 9, driving one end of the linkage rod 704 to approach the side of the base 9. At the same time, the other end of the linkage rod 704 slides upward and pushes the trigger seat 702 to move upward. The trigger seat 702 slides upward in the guide rail 703. The upward movement of the trigger seat 702 drives the trigger rod 701 to move upward and reset. At this time, the square groove on the upper surface of the locking rod 705 coincides with the T-shaped groove on the upper surface of the base 9, and the locking mechanism 7 releases the restriction on the two lower mold frames 10.

[0033] After the locking mechanism 7 releases the restriction on the two lower mold frames 10, the partition 3 moves upward and pulls the demoulding mechanism 6 to separate the two lower mold frames 10. The partition 3 moves upward and pulls the sliding seat 601 upward. The sliding seat 601 moves upward and pulls one end of the push rod 602 upward. Under the action of the middle limiting rod 605, the other end of the push rod 602 moves outward and drives the push seat 609 to move outward. The push seat 609 moves outward and drives the two lower mold frames 10 to move in the opposite direction. The compression spring 1001 releases the pressure and drives the two lower mold frames 10 to move in the opposite direction. At this time, the two lower mold frames 10 are separated.

[0034] After the electric telescopic rod 14 pushes the formed elliptical head 15 upward, the unloading mechanism 5 enters the equipment to take out the stamped elliptical head 15, and the travel motor 505 drives the unloading body 512 to slide on the outside of the slide rail 503, and the unloading body 512 drives the lifting frame 501 to move to the lower mold frame 10, and the lifting frame 501 moves to the bottom of the formed elliptical head 15, and the electric telescopic rod 14 shrinks, and the formed elliptical head 15 falls on the lifting frame 501, and at this time the travel motor 505 rotates in the opposite direction to take out the stamped elliptical head 15, and the steering motor 508 Start, the output end of the steering motor 508 drives the worm 509 to rotate, the worm 509 is meshed with the worm wheel 510, the rotation of the worm 509 drives the worm wheel 510 to rotate, the rotation of the worm wheel 510 drives the steering shaft 511 to rotate, the rotation of the steering shaft 511 drives the lifting frame 501 to rotate, the steering motor 508 drives the lifting frame 501 to rotate 180 degrees, and then the heated plate 16 is sent into the equipment, and the staff removes the stamped elliptical head 15, which reduces the labor intensity of the staff, shortens the production time of a single product, and improves production efficiency.

[0035] When the cooling mechanism 8 cools the upper mold frame 11, the input end of the water pump 803 uses the refilling tube 802 to extract the coolant from the water tank 801, and the coolant enters the surrounding pipeline inside the upper mold frame 11 from the output end of the water pump 803 through the cooling water pipe 804. The coolant cools the upper mold frame 11, and the cooled coolant enters the water pump 803 through the cooling water pipe 804. The cooled coolant flows back from the water pump 803 through the refilling tube 802 to the water tank 801. The upper mold frame 11 is cooled by this reciprocating cycle to prevent the formed elliptical head 15 from being stuck on the outside of the upper mold frame 11, which makes demolding difficult and reduces production efficiency.

[0036] When the upper mold frame 11 needs to be replaced, first start the hydraulic telescopic rod 2 17 to move the partition 3 to the lowermost end, and then start the hydraulic telescopic rod 12 to make the upper mold frame 11 contact with the output end of the electric telescopic rod 14, and then use a wrench to rotate the locking bolt 1102. The locking bolt 1102 rotates and pulls the locking block 1103 to disengage from the output end of the hydraulic telescopic rod 12. At this time, reset the hydraulic telescopic rod 2 17 and the hydraulic telescopic rod 12 to take out the upper mold frame 11. When the lower mold frame 10 needs to be replaced, remove the limit pin 608, pull out the limit shaft 607, and start the hydraulic telescopic rod 2 17 to drive the partition 3 to move upward. At this time, the two lower mold frames 10 can be removed. When the size of the stamping product changes and the base 9 needs to be adjusted, use a wrench to rotate the limit bolt 1303. After the limit bolt 1303 is disconnected from the limit block 1302, the fixed block 1301 is pulled out. At this time, the base 9 can be removed for replacement.

At this time, the square groove on the upper surface of the locking rod 705 is misaligned with the T-shaped groove on the upper surface of the base 9, blocking the T-shaped blocks on the lower surfaces of the two lower mold frames 10 to prevent the two lower mold frames 10 from retreating; S4, after the locking mechanism 7 locks the two lower mold frames 10, the hydraulic telescopic rod 12 is started to push the upper mold frame 11 to move downward, and the upper mold frame 11 moves downward to punch the plate 16 into an elliptical head 15; S5, after the elliptical head 15 is stamped and formed, the hydraulic telescopic rod 2 17 is first started to pull the partition 3 upward, the partition 3 moves upward to pull the locking mechanism 7 to release the restriction on the two lower mold frames 10, and the partition 3 moves upward to pull the demoulding mechanism 6 to separate the two lower mold frames 10; S6, after the two lower die frames 10 are separated, the electric telescopic rod 14 is first started to push the formed elliptical head 15 upward, and then the unloading mechanism 5 is started to take out the stamped elliptical head 15, and the plate 16 is placed in the equipment for the next round of stamping.
