[0004] Although the above-mentioned equipment can disturb the quenching medium to better quench the metal material when in use, it is inconvenient to remove the metal material after quenching, and the use of a servo motor to drive the stirring blade to rotate will increase its use cost.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 5 As shown, the utility model provides a heat treatment equipment for metal material manufacturing, including a support frame 1, a heating box 3 is installed on the inner side of the support frame 1, a hydraulic cylinder 2 is installed above the support frame 1, a top plate 7 is installed on the output end of the hydraulic cylinder 2, a storage plate 6 is installed below the top plate 7, and piston blocks 10 are provided at both ends of the storage plate 6. A quenching box 13 is provided below the heating box 3, a connecting box 16 and a connecting pipe 19 are provided inside the quenching box 13, and a connecting pipe 17 is installed on the top plate 7.

[0025] The heating box 3 is used to heat the metal material, the storage plate 6 is used to support the metal material, the piston block 10 is used to compress the quenching medium inside the quenching box 13, the connecting box 16 cooperates with the connecting pipe 19 to spray the quenching medium to pre-cool the metal material, and the connecting pipe 17 is used to drive the connecting pipe 19 to swing back and forth.

[0026] In a further embodiment, both ends of the storage plate 6 are fixedly connected to the heat insulation plate 8 , the top end of the heat insulation plate 8 is fixedly connected to the top plate 7 , and both ends of the top plate 7 are fixedly connected to the connecting frames 9 .

[0027] In this embodiment, the length of the heat insulation board 8 is greater than the radiation range of the electric heating tube 4, thereby preventing heat from escaping to the connecting frame 9; the gap between the heat insulation board 8 and the connecting frame 9 can be used for the insertion of the partition 14.

[0028] In a further embodiment, the connecting frames 9 are located at both ends of the storage plate 6 , the piston block 10 is fixedly connected below the connecting frames 9 , and a rubber ring 11 surrounds the outer periphery of the piston block 10 .

[0029] In this embodiment, when the outer periphery of the rubber ring 11 enters the interior of the quenching box 13, it can fit into the gap between the partition 14 and the inner wall of the quenching box 13, thereby squeezing the quenching medium below, so that the quenching medium can pass through the connecting box 16 and the connecting pipe 17 into the interior of the connecting pipe 19 and be quickly sprayed out from the nozzle 20.

[0030] In a further embodiment, an electric heating tube 4 is installed on the inner side of the heating box 3 , and through grooves 5 are opened on both sides of the heating box 3 , and the through grooves 5 are used to cooperate with the intermittent racks 12 .

[0031] In this embodiment, the through slot 5 is used for the intermittent rack 12 to pass through during the continuous downward movement of the top plate 7.

[0032] In a further embodiment, a partition 14 is installed inside the quenching box 13, and the partition 14 is provided with evenly arranged through holes 15. The two sides of the quenching box 13 are fixedly connected with receiving blocks 18, and the two ends of the connecting pipe 19 are fixedly connected with linkage shafts 21.

[0033] In this embodiment, the interior of the quenching box 13 is divided into three areas by the partition 14, and the three areas are connected by the through hole 15. The left and right areas are the areas where the piston block 10 enters; the through hole 15 is opened at a rotation position higher in the middle of the partition 14, so when the piston block 10 reaches the top of the connecting box 16, the quenching medium can be compressed, and when the piston block 10 leaves, the quenching medium above the piston block 10 can be replenished to the top of the connecting box 16.

[0034] In a further embodiment, the connecting pipe 19 is rotatably connected to the inside of the receiving block 18 through a linkage shaft 21 , one end of the connecting box 16 is connected to the connecting pipe 17 , and the other end of the connecting pipe 17 is connected to the connecting pipe 19 .

[0035] In this embodiment, the outer side of the quenching box 13 is provided with an inlet and outlet port for replacing the quenching medium inside the quenching box 13 .

[0036] In a further embodiment, one side of the connecting pipe 19 is installed with evenly arranged nozzles 20, one end of the linkage shaft 21 is fixed with a gear 22, the gear 22 cooperates with the intermittent rack 12, one side of the gear 22 is connected to a torsion spring 23, and the other end of the torsion spring 23 is connected to the receiving block 18.

[0037] In this embodiment, the intermittent rack 12 is composed of short racks and connecting blocks arranged at intervals. Therefore, when the short rack is engaged with the gear 22, the gear 22 will rotate with the linkage shaft 21 and the connecting tube 19, while the connecting block cannot be engaged with the gear 22. Under the rebound of the torsion spring 23, the linkage shaft 21, gear 22 and the connecting tube 19 can be rotated back and forth.

[0038] The working principle of this utility model is as follows:

[0039] After the metal material is placed on the storage plate 6, the hydraulic cylinder 2 can be operated to move the top plate 7 with the storage plate 6 and the heat insulation plate 8 downward until the top plate 7 reaches the upper end of the heating box 3. The hydraulic cylinder 2 stops operating, and then the electric heating tube 4 is operated to heat the metal material placed on the storage plate 6. After heating for a certain period of time, the operation of the electric heating tube 4 can be paused and the hydraulic cylinder 2 can be restarted to move the top plate 7 with the storage plate 6 further downward until the top plate 7 reaches the upper end of the quenching box 13. The hydraulic cylinder 2 stops operating, and the metal material can be quenched. After the treatment is completed, the hydraulic cylinder 2 can be started again to move the top plate 7 with the storage plate 6 upward until the storage plate 6 leaves the interior of the heating box 3, thereby facilitating the removal of the quenched metal material.

[0040] When the top plate 7 reaches the upper end of the heating box 3, the insulation plate 8 will block part of the temperature to make the heating more concentrated, and at this time the piston block 10 and the rubber ring 11 will reach the inside of the quenching box 13 and be located on one side of the partition 14. In addition, at this time, one end of the intermittent rack 12 will also contact the gear 22. As the heating ends, the top plate 7 continues to move downward, causing the piston block 10 and the rubber ring 11 to compress the quenching medium on one side of the partition 14 and above the connecting box 16, and causing the quenching medium to be quickly ejected from the nozzle 20 through the connecting pipe 17 and the connecting pipe 19. During the ejection, due to the contact and intermittent engagement of the intermittent rack 12 and the gear 22, the connecting pipe 19 rotates back and forth around the linkage shaft 21. Therefore, not only can the metal material be sprayed with the quenching medium when it enters the interior of the quenching box 13, thereby pre-cooling the metal material, and then completely immersed in the quenching medium inside the quenching box 13, thereby reducing quenching stress and deformation.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
