Description

Technical Field

[0001] The utility model belongs to the technical field of ductile iron, in particular to a heating device for ductile iron castings. Background Art

[0002] Ductile iron is a high-strength cast iron material characterized by the addition of spherical graphite to the cast iron matrix. The graphite is made spherical by adding magnesium or rare earth metals during the casting process, thereby significantly improving the plasticity and toughness of the cast iron. During the production process of ductile iron, heating equipment is required to melt it.

[0003] During use of the existing heating device, ductile iron needs to be placed on a trolley, which is moved into the heating device via a track, and then the upper door is moved into the slot on the trolley by a motor, thereby sealing the interior of the device. When the door is not in use, it can be moved upward by a motor. During the movement of the door, only the rope provides force for the door. After long-term use, the rope is overloaded due to the heavy door, which reduces the service life of the rope. Therefore, a heating device with multiple auxiliary supports is needed to extend the service life of the rope. Utility Model Content

[0004] The present invention aims to solve the problem that in the prior art, the existing heating device needs to be placed on a trolley during use. The trolley is moved into the heating device via a track, and then the upper door is moved into the slot on the trolley by a motor, so that the interior of the device is sealed. When the door is not in use, it can be moved upward by the motor. During the movement of the door, only the rope provides force for the door.

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] See also Figure 1-Figure 3 As shown, this embodiment is a heating device for ductile iron castings, comprising:

[0031] Heating assembly, the heating assembly includes a support frame 12, a movable door 14 and a rope 15;

[0032] The support frame 12 is used to connect the motor 13, the movable door 14 is used to seal the interior of the body 11, and the rope 15 is used to raise and lower the movable door 14;

[0033] Auxiliary support assembly, the auxiliary support assembly includes a connecting frame 21, a spring 22, a support plate 23, a magnetic block 27 and a pull rod 28;

[0034] The connecting frame 21 is fixed to both sides of the support frame 12, the spring 22 is fixed to the inner side of the connecting frame 21, the support plate 23 is fixed to the other end of the spring 22, the magnetic block 27 is fixed to the inner side of the connecting frame 21 and is located outside the spring 22, and the pull rod 28 is fixed to one side of the support plate 23 and is located inside the spring 22;

[0035] The connecting frame 21 is used for connecting the spring 22 and moving the pull rod 28. The spring 22 is used to connect the support plate 23 and the connecting frame 21. The support plate 23 is used to place the bottom end of the movable door 14. The magnetic block 27 is used to connect the support plate 23 and the connecting frame 21. The pull rod 28 is used to move the support plate 23.

[0036] The bottom end of the support plate 23 is fixedly connected to a moving rod 24, and the inner lower side of the connecting frame 21 is fixedly connected to a supporting rod 25, and the bottom end of the moving rod 24 is slidably connected to the inner side of the outer end of the supporting rod 25;

[0037] The other end of the pull rod 28 extends to the outside of the connecting frame 21;

[0038] The moving rod 24 and the supporting rod 25 are both used to support the supporting plate 23. When the supporting plate 23 moves, the moving rod 24 moves accordingly. The pull rod 28 is slidably connected to the inside of the connecting frame 21.

[0039] One side of the support plate 23 is attracted to the magnetic block 27, and one side of the bottom end of the support plate 23 is provided with an inclined surface 26;

[0040] A slot 231 is formed on the inner side of the support plate 23;

[0041] When the support plate 23 moves to the inner side of the connecting frame 21, the magnetic block 27 is attracted to one side of the support plate 23, so that the magnetic block 27 limits the support plate 23 after movement. The slot 231 is used for placing and clamping the bottom end of the movable door 14;

[0042] Working principle:

[0043] When in use, the motor 13 drives the movable door 14 upward through the rope 15. At this time, the top of the movable door 14 contacts the inclined surface 26 at the bottom of the support plate 23. Then, the force of the movable door 14 moves through the inclined surface 26 to push the support plate 23, so that the support plate 23 moves to both sides through the spring 22. At the same time, the support plate 23 pushes the pull rod 28 to move outward, and the movable rod 24 moves toward the inside of the support rod 25. After the support plate 23 moves, the movable door 14 moves upward through the rope 15.

[0044] Subsequently, the force of the squeezing spring 22 disappears, and the spring 22 reacts on the support plate 23, causing the spring 22 to drive the support plate 23 to pop out, so that the bottom end of the movable door 14 is engaged with the locking groove 231, so that the support plate 23 auxiliary supports the movable door 14, thereby preventing the rope 15 from being overloaded;

[0045] When the movable door 14 moves downward, the staff pulls the pull rod 28 by hand, so that the pull rod 28 drives the support plate 23 to move to both sides through the spring 22, and the movable rod 24 moves along with the support plate 23. When the support plate 23 moves to the inner side of the connecting frame 21, the magnetic block 27 is attracted to one side of the support plate 23, so that the magnetic block 27 limits the moved support plate 23, thereby facilitating the downward movement of the movable door 14;

[0046] In the above steps, the support plate 23 can be driven to move through the interaction between the pull rod 28 and the inclined surface 26 .

[0047] See also Figure 1 、 Figure 4-Figure 5 As shown, this embodiment further includes, based on the above embodiment 1;

[0048] Anti-mismovement components;

[0049] The anti-mismovement assembly includes a groove 31, a movable plate 32 and a limiting rod 33;

[0050] The grooves 31 are formed at the edges of both sides of the movable door 14, the movable plate 32 is clamped to the outer side of the support frame 12, and the limiting rod 33 rotates and passes through the connection between the movable plate 32 and the support frame 12;

[0051] The groove 31 is used for connecting the movable plate 32, and the movable plate 32 is used for connecting the movable door 14 and the support frame 12. The limiting rod 33 limits the connection between the movable plate 32 and the support frame 12;

[0052] The limiting rod 33 is provided with a limiting hole 34 at the connection between the movable plate 32 and the support frame 12. A connecting shaft 35 is fixedly connected inside the groove 31. The other end of the movable plate 32 is sleeved with the connecting shaft 35.

[0053] The limiting hole 34 is used for inserting the limiting rod 33, and the limiting rod 33 is threadedly connected to the limiting hole 34. The connecting shaft 35 is used for rotating the movable door 14. The movable door 14 can only rotate ninety degrees.

[0054] The heating assembly also includes a body 11 and a motor 13;

[0055] The movable door 14 is closely attached to one side of the machine body 11, the support frame 12 is fixed to the edges of both ends of one side of the machine body 11, the motor 13 is fixed to both sides of the top of the support frame 12, and the rope 15 is fixed between the movable door 14 and the motor 13;

[0056] The body 11 is used to connect other components such as the movable door 14, and the motor 13 drives the movable door 14 up and down through the rope 15;

[0057] Working principle:

[0058] When the movable door 14 moves to be close to one side of the machine body 11, the staff manually rotates the movable plate 32 so that the movable plate 32 rotates through the connecting shaft 35. After the movable plate 32 rotates, it engages with the lower side of the support frame 12. Then, the limiting rod 33 is inserted into the limiting hole 34 at the connection between the movable plate 32 and the support frame 12, and the limiting rod 33 is rotated so that the movable plate 32 is connected to the support frame 12, thereby limiting the movable plate 32 and preventing the movable door 14 from accidentally opening or moving up due to a malfunction.
