[0019] The invention will now be further described with reference to the accompanying drawings.

[0020] like Figures 1-7 The present invention discloses a novel automatic tempering device for forged rods, comprising a tempering furnace 1, a cooling water tank 8, and a transfer mechanism 12. The cooling water tank 8 is dug in the ground to the right of the tempering furnace 1, and the transfer mechanism 12 is installed in the ground by bolts. The transfer mechanism 12 extends through the tempering furnace 1 to directly above the cooling water tank 8. A lifting assembly 17 is provided in the cooling water tank 8. A storage basket 27 is placed on the lifting assembly 17 and the transfer mechanism 12. The storage basket 27 containing the rods is placed on the transfer mechanism 12, and the storage basket 27 is transported into the tempering furnace 1 for tempering by the transfer mechanism 12. After tempering, the storage basket 27 in the tempering furnace 1 is transferred to the top of the lifting assembly 17 by the transfer mechanism 12. The tempered storage basket 27 is immersed in the cooling water tank 8 for cooling by the lifting assembly 17. After cooling, the lifting assembly 17 removes the storage basket 27 from the cooling water tank 8. The tempering furnace 1 has a material switching assembly 2 at the bottom. The material switching assembly 2 includes an insulation box 3 and a lifting assembly 4. There is a discharge notch 6 at the bottom of the tempering furnace 1. There is a slot in the discharge notch 6. A retractable sealing plate 7 is inserted into the discharge notch 6. The two ends of the sealing plate 7 protrude from the tempering furnace 1. The first hydraulic cylinder is fixed between the front and rear ends of the tempering furnace 1 and the sealing plate 7 by bolts. The insulation box 3 is installed at the bottom of the tempering furnace 1 by bolts. When the sealing door is opened, the bottom of the tempering furnace 1 is connected to the insulation box 3. The sealing door separates the insulation box 3 from the tempering furnace 1. The lifting assembly 4 is set at the bottom of the insulation box 3. The lifting assembly 4 lifts the storage basket 27 in the safe into the tempering furnace 1. Then the sealing door is closed. This tempering can effectively prevent the heat loss in the tempering furnace 1. The transfer mechanism 12 includes support plates 13 and a conveyor chain 14. There are two support plates 13, which are connected to the left and right ends of the insulated box 3. The insulated box 3 is fixed to the support plates 13 by bolts. The insulated box 3 can hold two storage baskets 27. Channels are opened on the left and right sides of the insulated box 3, and lifting doors 9 are inserted into these channels. A cylinder is fixed to the top of the lifting door 9 and the top of the insulated box 3 by bolts. The cylinders raise and lower the lifting door 9, opening and closing the channels of the insulated box 3. When storage baskets 27 need to enter / exit the insulated box 3, the lifting door 9... When the door 9 is opened, the lifting door 9 can only descend to close the passage. There are conveying grooves 16 at the bottom of the support plate 13 and the insulation box 3 for the conveying chain 14 to be inserted. At the left and right ends of the support plate 13, there are sprockets driven by motors installed through bearings. The conveying chain 14 meshes with the two sprockets. The top of the conveying chain 14 is flush with the top of the support plate 13. A push block 15 for pushing the storage basket 27 is installed on the conveying chain 14 by bolts. When the storage basket 27 is placed on the support plate 13, the movement of the conveying chain 14 drives the push block 15 to move, and the push block 15 pushes the storage basket 27 to the right. A cooling water tank 8 is installed below the right end of the support plate 13. A lifting assembly 17 is connected to the right end of the support plate 13. The storage basket 27 is lifted and lowered by the lifting assembly 17, so that the storage basket 27 can be placed into the cooling water tank 8.

[0021] The storage basket 27 has openings at both the front and rear ends. The outer walls of the front and rear sides of the storage basket 27 are welded together via a fixing frame 28 located at the openings at both ends. Multiple layers of adjustable partition bars 29 are placed inside the storage basket 27. Each layer of bars is placed on a partition bar 29, and each layer of bars 29 is connected via a linkage rod 30. The linkage rod 30 is welded and fixed to each partition bar 29, allowing for synchronous lifting and lowering of each layer of bars 29. The sides of each layer of bars 29 slide against the inner side of the storage basket 27 (slots are provided on the left and right inner sides of the storage basket 27, into which the ends of the partition bars 29 engage for lifting and lowering). Cross-shaped connecting rods 31 are installed at the front and rear ends of adjacent partition bars 29. The left end of each connecting rod 31 is hinged to a partition bar 29, and the right end of the connecting rod... The end of the rod slides with the spacer 29 (a slide rail is fixed to the spacer 29 by welding, and a movable seat that moves on the slide rail is locked on the slide rail; the right end of the connecting rod is hinged to the movable seat). An inclined block 32 is installed on the movable seat by welding. A guide rod 33 passes through the fixing frame 28 at both ends of the storage basket 27. The guide rod 33 moves back and forth along the fixing frame 28. An inclined strip 34 is installed on the end of the guide rod 33 inside the storage basket 27 by welding. A spring is fitted on the guide rod 33 to pull the guide rod 33 outward. The inclined strip 34 contacts the inclined surface of multiple inclined blocks 32. When the guide rod 33 is squeezed, the inclined block 32 moves to the left, the interval between the spacers 29 increases, and the height difference between the two rods is increased, so that the heat flow is good, thus ensuring the tempering and cooling effect.

[0022] The sealing door consists of two pieces, which slide in conjunction with the unloading notch 6. A first hydraulic cylinder is installed between the sealing door and the unloading notch 6 by bolts, which enables the two sealing doors to close and open. Push rods 10 pass through both ends of the tempering furnace 1. The push rods 10 are coaxial with the guide rods 33 and slide through the outer wall of the tempering furnace 1. A pressure plate 11 is fixed to the end of the sealing door near the first hydraulic cylinder by welding. The pressure plate 11 is located outside the tempering furnace 1. When the sealing door is closed, the pressure plate 11 pushes the push rods 10 inward, thus increasing the height difference between the spacers 29.

[0023] The lifting component 4 is the support rod 5. A groove is opened at the bottom of the insulation box 3 for the support rod 5 to be inserted. When the support rod 5 is inserted into the groove of the safe, the top of the support rod 5 is flush with the bottom of the insulation box 3. A second hydraulic cylinder is installed at the bottom of the insulation box 3 by bolt fastening. The piston rod of the second hydraulic cylinder extends into the insulation box 3 and is fixed to the support rod 5 by welding. The lifting and lowering of the support rod 5 is achieved by the second hydraulic cylinder, and the lifting and lowering of the storage box is achieved by the support rod 5.

[0024] The lifting assembly 17 includes a lifting plate 18, a gantry frame 19, and a limiting plate 20. The gantry frame 19 is bolted to the top of the cooling water tank 8. The lifting plate 18, flush with the support plate 13, is installed below the gantry frame 19. A third hydraulic cylinder is bolted between the gantry frame 19 and the lifting plate 18, enabling the lifting plate 18 to rise and fall. A movable limiting plate 20 is located at the bottom of the cooling water tank 8. When the lifting plate 18 moves to the bottom of the cooling water tank 8, the limiting plate 20 moves inward, pressing against the guide rod 33 on the storage basket 27. The limiting plate 20 slides against the inner wall of the cooling water tank 8 (a straight rod is welded to the back of the limiting plate 20, sliding through the inner wall of the cooling water tank 8, thus enabling the translation of the limiting plate 20). A first rack 21 is welded to the bottom of the limiting plate 20. A groove 24 is provided, and two sliders 25 are engaged within the groove 24 and move horizontally within it. The sliders 25 are lower than the top of the groove 24. The two sliders 25 are hinged together by two connecting rods. An elastic component 26 (which is a spring, with both ends of the elastic component 26 fixed to the inner sides of the groove 24 and the sliders 25 by welding) is provided between the sliders 25 and the groove 24. The elastic component 26 enables the two sliders 25 to move closer together. A second rack 22 is fixed to the outside of each slider 25 by welding. The second rack 22 slides within the groove 24. A gear 23 is provided between the first rack 21 and the second rack 22, meshing with both racks. The gear 23 is mounted on the inner wall of the cooling water tank 8 via bearings and bearing seats. When the second rack 22 moves outward, the first rack 21 moves inward, and the limiting plate 20 presses down on the guide rod 33.

[0025] A discharge assembly 35 is provided on the right side of the lifting assembly 17. The discharge assembly 35 consists of two parallel pressure rods 36, which are bolted to the ground. When the lifting assembly 17 is raised, the lifting plate 18 is flush with the pressure rods 36. When the storage basket 27 is placed on the pressure rods 36 for conveying, a rotating plate 37 is rotatably connected to the end of one of the pressure rods 36 (one end of the rotating plate 37 is equipped with a rotating shaft that extends into one end of the pressure rod 36, thus achieving...). The rotating plate 37 is an L-shaped plate. A reciprocating assembly 37 is set between the rotating plate 37 and the ground (the reciprocating assembly 37 is an eccentric wheel driven by a motor, with a ring on the eccentric wheel and the ring in contact with the bottom of the rotating plate 37). The reciprocating assembly 37 realizes the swing of the rotating plate 37. When the rotating plate 37 swings down, the storage basket 27 tilts, so the rods in the storage basket 27 tip out. The few rods blocked by the cross link 31 can be taken out manually.
