Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and specifically to an automatic demolding hammer for cast iron molds. Background Technology

[0002] In the process of metal smelting, cast iron molds are an important tool for transferring molten iron. The main conveying system includes a conveyor structure similar to a conveyor belt, a rotor structure that drives the conveyor structure to rotate, multiple cast iron molds are closely arranged on the conveyor structure, and the two ends of the rotor structure are provided with raised driving parts for driving the movement of the cast iron molds.

[0003] During the operation of the above system, the molten iron will solidify inside the cast iron mold due to the drop in temperature and adhere to the inside of the cast iron mold. As the system runs for a longer period of time, the molten iron inside the cast iron mold will solidify, resulting in more and more iron blocks sticking to the iron mold.

[0004] The traditional method involves hammering each cast iron mold individually, which is labor-intensive and inefficient, and also fails to completely demold the iron block. Utility Model Content

[0005] To address the technical problems of low manpower consumption and efficiency in traditional methods of cleaning molten iron from cast iron molds, this utility model provides an automatic demolding hammer for cast iron molds. By matching the drive rod with the drive part on the rotor structure, the rotor structure can drive the crossbar to rotate when it rotates. In turn, the crossbar drives the hammer body to rotate upward and away from the cast iron mold. Thus, when the drive rod and the drive part separate, the hammer body can strike the cast iron mold, thereby cleaning the molten iron from inside the cast iron mold.

[0006] The technical solution of this utility model is:

[0007] An automatic demolding hammer for cast iron molds, mounted on a gantry of a cast iron mold transport system, includes:

[0016] Optionally, the hammer body further includes a support rod, the two ends of which are fixedly connected to the ends of the two connecting rods away from the crossbeam; the support rod is provided with a plurality of hammer heads.

[0017] Optionally, the length of the support rod is less than the length of the cast iron mold, and the height of the hammer protruding from the surface of the support rod is greater than the depth of the cast iron mold.

[0018] Optionally, the length direction of the drive rod and the length direction of the connecting rod form an angle of 25° to 45°.

[0019] Optionally, the hammerhead has a disc-shaped structure.

[0020] Optionally, a drive rod is provided at each end of the crossbeam, and the two drive rods are arranged symmetrically.

[0021] Optionally, a positioning pin is provided between the drive rod and the crossbeam, and one end of the two drive rods, which are L-shaped, is respectively matched with the drive parts at both ends of the rotor structure.

[0022] Optionally, a connecting seat is provided at each end of the crossbeam, the connecting seat is provided on the gantry, and the crossbeam is rotatably connected to the connecting seat.

[0023] Optionally, a bearing is provided between the connecting seat and the crossbeam.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] By matching the drive rod with the drive unit on the rotor structure, the rotor structure can drive the crossbar to rotate when it rotates. In turn, the crossbar drives the hammer body, which can rotate upward and move away from the cast iron mold. When the drive rod and the drive unit separate, the hammer body can strike the cast iron mold and clean the condensed iron block inside the cast iron mold.

[0026] This technical solution can quickly and effectively clean the solidified iron blocks inside the cast iron mold. Moreover, the cast iron mold is hammered after each transport of molten iron, so the solidified iron blocks inside the cast iron mold are difficult to remain. Attached Figure Description

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example:

[0035] See Figure 1 and Figure 2 This embodiment discloses an automatic demolding hammer for cast iron molds. The hammer is mounted on a gantry 11 of a cast iron mold 14 transport system. The transport system includes a rotor structure 12 that rotates continuously and drives all cast iron molds 14 to move. All cast iron molds 14 form a conveyor belt structure. Furthermore, the rotor structure 12 has multiple protruding drive portions 13 at both ends.

[0036] Specifically, the striking hammer includes a crossbeam 20, a hammer body 30, and a drive rod 40. The two ends of the crossbeam 20 are rotatably mounted on the gantry 11, and the crossbeam 20 is arranged in a horizontal direction and is also located above the cast iron mold 14.

[0037] One end of the hammer body 30 is fixedly mounted on the crossbeam 20, while the other end is in a free state and can rotate with the crossbeam 20. The other end of the hammer body 30 can contact the cast iron mold 14, and under the action of gravity, it can strike the cast iron mold 14.

[0038] One end of the drive rod 40 is also fixedly mounted on the crossbeam 20, and there is an angle between the length direction of the drive rod 40 and the length direction of the hammer body 30. The other end of the drive rod 40 is an L-shaped structure 41, and the end of the drive tube with the L-shaped structure 41 can contact the drive part 13 on the rotor structure 12.

[0039] During the rotation of the rotor structure 12, the drive unit 13 applies downward pressure to one end of the drive rod 40, which is an L-shaped structure 41. This causes the drive rod 40 to drive the crossbeam 20 to rotate, which in turn causes the end of the hammer 30 to move upward along an arc. After the rotor structure 12 rotates to a certain angle, the drive unit 13 separates from the L-shaped end of the drive rod 40, and under the action of gravity, the hammer 30 moves downward and strikes the cast iron mold 14.

[0040] Since multiple drive units 13 are evenly distributed on the rotor structure 12, the rotor structure 12 can continuously drive the hammer 30 to strike the cast iron mold 14.

[0041] This technical solution can quickly and effectively clean the condensed iron blocks inside the cast iron mold 14. Moreover, the cast iron mold 14 is hammered once after each transport of molten iron, so the condensed molten iron inside the cast iron mold 14 is difficult to retain.

[0042] In one specific embodiment:

[0043] The hammer body 30 mentioned above includes a connecting rod 31 and a hammer head 32, wherein one end of the connecting rod 31 is fixedly mounted on the crossbeam 20, and the hammer head 32 is mounted on the other end of the connecting rod 31.

[0044] Preferably, two connecting rods 31 are arranged in parallel on the crossbeam 20, and a support rod 33 is arranged between the two connecting rods 31. The support rod 33 is arranged in parallel with the crossbeam 20, and the two ends of the support rod 33 are fixedly connected to the ends of the connecting rods 31 away from the crossbeam 20.

[0045] Multiple hammerheads 32 are provided on the support rod 33. In this technical solution, the hammerheads 32 produce a striking effect on the cast iron mold 14. The striking force can be increased by providing multiple hammerheads 32. Since multiple hammerheads 32 are provided, two connecting rods 31 are provided to improve the structural strength.

[0046] Generally, the length of the support rod 33 is less than the length of the cast iron mold 14, and the height of the hammer head 32 protruding from the surface of the support rod 33 is greater than the depth of the cast iron mold 14. This design can reduce the weight of the entire hammer, making it easier to install and maintain.

[0047] In another specific embodiment:

[0048] The length direction of the drive rod 40 forms an angle with the length direction of the connecting rod 31, which is between 25° and 45°. Since there are generally eight drive units 13 on the rotor structure 12, and the installation position of the crossbeam 20 needs to be maintained at more than one meter above the highest cast iron mold 14, this angle is designed to maximize the lifting height of the hammer head 32.

[0049] In another specific embodiment:

[0050] To reduce the destructive power of the hammerhead 32 on the cast iron mold 14, the hammerhead 32 is designed as a disc-shaped structure, which also increases the strength of the hammerhead 32.

[0051] In another specific embodiment:

[0052] A drive rod 40 is provided at each end of the crossbeam 20. The two drive rods 40 are symmetrically arranged. Since the drive part 13 is symmetrically arranged at both ends of the rotor structure 12, the service life of a single drive rod 40 can be improved by symmetrically arranging drive rods 40 at both ends of the crossbeam 20.

[0053] Preferably, a positioning pin is provided between the drive rod 40 and the crossbeam 20, and one end of the two drive rods 40, which are L-shaped structures 41, are respectively matched with the drive parts 13 at both ends of the rotor structure 12.

[0054] In another specific embodiment:

[0055] A connecting seat 50 is provided at each end of the crossbeam 20. The connecting seat 50 is mounted on the gantry 11, and the crossbeam 20 is rotatably connected to the connecting seat 50. A bearing is provided between the connecting seat 50 and the crossbeam 20. Since the gantry 11 is the supporting structure of the existing equipment, it is necessary to provide the connecting seat 50. The connecting seat 50 is fixed to the gantry 11 by bolts through holes, and the crossbeam 20 is rotatably mounted on the connecting seat 50 by bearings.

[0056] In another specific embodiment:

[0057] The protruding structure forming the L-shaped structure 41 at the end of the drive rod 40 can also be installed on the rotor structure 12 as needed, and multiple protruding structures can be evenly installed around the circumference of the rotor structure 12. The drive rod 40 is directly driven by the protruding structures on the rotor structure 12, thereby adapting to the needs of different scenarios. In addition, wear-resistant sleeves can be installed on the protruding structures to enhance wear resistance.

[0058] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
