Technical Field

[0001] This utility model relates to the technical field of forging furnaces for machining ship drive shafts, and in particular to a forging furnace for machining ship drive shafts. Background Technology

[0002] The ship's drive shaft is a key component in the ship's propulsion system. It is mainly used to transfer power from a power source (such as an engine or electric motor) to the propeller, thereby enabling the ship to navigate.

[0003] Ship drive shafts are manufactured through forging. Generally, the blank is heated in a forging furnace before further forging. When using existing forging furnaces, the furnace door needs to be opened, and a special clamp is used to fill the blank into the furnace. After heating, the furnace door is opened again, and a special clamp is used to remove the blank from the furnace. However, opening the furnace door requires manual operation, and when placing or removing blanks from the furnace, the clamp needs to be extended into the furnace. This restricts the handling of blanks by the furnace opening, making it inconvenient and impractical. Utility Model Content

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] Example

[0019] Please see Figures 1-4 This utility model discloses a forging furnace for machining ship drive shafts, comprising a forging furnace body 1, a furnace door frame 4, and a feeding platform 8. Furnace feet 2 are fixedly connected to the four corners of the bottom end of the forging furnace body 1. A furnace opening is provided on the lower side of the front end of the forging furnace body 1. The furnace door frame 4 is fixedly connected to the front end of the forging furnace body 1, with its top end aligned with the top end of the forging furnace body 1. A support plate 3 is fixedly connected to the front end of the forging furnace body 1, with its top end aligned with the lower edge of the furnace opening. The bottom end of the furnace door frame 4 is fixedly connected to the top end of the support plate 3. A hydraulic cylinder 5 is fixedly installed in the middle of the top of the furnace door frame 4. A furnace door 6 is slidably installed in section 4. A connecting block 7 is fixedly connected to the top of the furnace door 6. The top of the connecting block 7 is fixedly connected to the output end of the hydraulic cylinder 5. Sleeve plates 9 are fixedly connected to the rear sides of both ends of the feeding platform 8. Guide columns 10 are fixedly connected between the inner walls of both ends of the forging furnace body 1. Two sets of guide columns 10 are symmetrically distributed on the left and right sides of the furnace opening. Two sets of sleeve plates 9 are slidably fitted onto the two sets of guide columns 10 respectively. The feeding platform 8 is slidably installed inside the forging furnace body 1 through the cooperation of the sleeve plates 9 and the guide columns 10, and the bottom end of the feeding platform 8 is flush with the interior of the forging furnace body 1. At the bottom contact point, inner connecting shafts 11 are fixedly connected to the rear ends of both sides of the feeding platform 8. A transmission rod 12 is rotatably mounted on each of the two sets of inner connecting shafts 11. A connector 13 is fixedly connected to the lower rear end of the furnace door 6. Outer connecting shafts 14 are fixedly connected to both sides of the connector 13. The ends of the two sets of transmission rods 12 furthest from the inner connecting shafts 11 are rotatably mounted on the two sets of outer connecting shafts 14. In use, the hydraulic cylinder 5 is activated, allowing the furnace door 6 to open and close. During the opening process, the furnace door 6 can be opened and closed via the transmission rods. 12. Pull the feeding platform 8 towards the furnace opening. After the furnace door 6 is fully opened, the feeding platform 8 can be pulled outside the furnace opening. The billet can then be placed on the feeding platform 8. Then close the furnace door 6, allowing the feeding platform 8 to return with the billet to the forging furnace body 1 for heating. After heating, pull the feeding platform 8 out of the furnace opening and use the patented clamp to remove the billet from the feeding platform 8. Thus, when picking up and placing the billet, there is no need to manually open the furnace door or extend the clamp into the furnace, avoiding the restriction of the furnace opening and making it more convenient and practical to pick up and place the billet.

[0020] Two sets of T-shaped guide rods 15 are symmetrically fixedly connected to the top of the furnace door 6. The two sets of T-shaped guide rods 15 are slidably installed on the top of the furnace door frame 4. By setting the T-shaped guide rods 15, when the hydraulic cylinder 5 pushes the furnace door 6 to move, the furnace door 6 drives the T-shaped guide rods 15 to slide. Through the guidance of the T-shaped guide rods 15, the furnace door 6 moves more smoothly.

[0021] The left and right ends and the front end of the furnace door 6 are in contact with the inner walls of the left and right sides and the front inner wall of the furnace door frame 4, respectively, and the rear end of the furnace door 6 is in contact with the front end of the forging furnace body 1; this can limit the furnace door 6 so that the furnace door 6 can tightly seal the furnace opening.

[0022] Multiple sets of through slots 16 are equidistantly provided at the top of the feeding platform 8. By setting through slots 16, the contact area between the bottom of the blank and the top of the feeding platform 8 can be reduced, the air circulation at the bottom of the blank can be increased, and the blank can be heated more evenly.

[0023] The furnace door frame 4 is symmetrically and fixedly connected to the front end of the forging furnace body 1 with two sets of ribs 17 at both ends; by setting the ribs 17, the connection between the furnace door frame 4 and the forging furnace body 1 can be made more firm and stable.

[0024] This utility model discloses a forging furnace for processing ship drive shafts. Its working principle is as follows: Initially, the furnace door 6 is sealed at the furnace opening, with its bottom end resting against the support plate 3. The hydraulic cylinder 5 is activated, opening and closing the furnace door 6. During the opening process, the furnace door 6 drives the connecting head 13 upwards. The connecting head 13, through the transmission cooperation of the outer connecting shaft 14, the transmission rod 12, and the inner connecting shaft 11, pulls the feeding platform 8 towards the furnace opening. The feeding platform 8 drives the sleeve plate 9 to slide along the guide column 10. The guide column 10 limits the feeding platform 8, preventing it from detaching from the furnace opening. After the furnace door 6 is fully open, the feeding platform 8 can be pulled outside the furnace opening. Workers use a special clamp to place the blank onto the feeding platform 8, then close the furnace door 6, allowing the feeding platform 8, carrying the blank, to return to the forging furnace body 1 for heating. After heating, the feeding platform 8 is pulled out of the furnace opening, and the blank is removed from the feeding platform 8 using a patented clamp.

[0025] The forging furnace for processing ship drive shafts of this utility model has common mechanical installation, connection and setting methods, and can be implemented as long as it can achieve the beneficial effect. The hydraulic cylinder 5 of the forging furnace for processing ship drive shafts of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
