Description

Technical Field

[0001] This utility model relates to the field of mold steel heat treatment technology, and specifically to a hanger device for heat treatment of mold steel. Background Technology

[0002] In the production and processing of mold steel, heat treatment is a crucial step. By performing heat treatment processes such as quenching and annealing, the internal structure of the mold steel can be altered, thereby obtaining the desired mechanical properties. During heat treatment, a hanging device is usually required to suspend the mold steel to ensure that it is heated and treated evenly.

[0003] Currently, existing hanger devices for heat treatment of mold steel have relatively simple structures, mainly consisting of supports and lifting rings. However, during the quenching process of mold steel, rising flames are generated. These flames not only pose safety hazards to surrounding equipment and operators but may also affect the stability of the quenching process. Conversely, during the annealing process of mold steel, it is necessary to ensure smooth airflow around the hanger device to facilitate uniform cooling. Existing hanger devices cannot simultaneously meet the requirements for flame arrest during quenching and airflow during annealing, resulting in significant limitations in their application.

[0004] Therefore, it is of great significance to provide a hanger device for heat treatment of mold steel to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a hanger device for heat treatment of mold steel to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hanger device for heat treatment of mold steel includes a bottom support, with a support column vertically fixedly connected to the top corner of the bottom support, and the top ends of multiple support columns fixedly connected by a top support; a top crossbeam is fixedly installed in the middle of the top support, and multiple fire-resistant baffles are rotatably connected between the top crossbeam and the side wall of the top support; a sliding rod is slidably installed in the middle of the top crossbeam, with a blocking ring fixedly connected to the bottom end of the sliding rod and a lifting ring fixedly connected to the top end.

[0008] The fire-resistant partition extends to the outside of the top support and is fixedly connected to a double-layer sprocket. The two adjacent double-layer sprockets are connected by a synchronous chain drive.

[0009] One of the fire-resistant partitions has a drive sprocket installed at its first end. Side plates are fixedly connected to both sides of the bottom end of the top crossbeam. A rotating shaft is rotatably installed at the bottom end of the side plate. A drive sprocket is fixedly connected to the end of the rotating shaft. The drive sprocket and the drive sprocket are connected by a drive chain.

[0010] The blocking ring is elastically connected to the bottom end of the top crossbeam by a spring, and a toothed rod is fixedly provided at the bottom end of the blocking ring.

[0011] A gear is fixedly installed in the middle of the rotating shaft, and the gear meshes with the rack.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by setting a rotatable fire-resistant partition, allows the fire-resistant partition to unfold during the quenching treatment of mold steel, thereby blocking the rising flames and preventing the flames from causing safety hazards to surrounding equipment and operators, thus improving the safety of the quenching process.

[0014] 2. When annealing mold steel, the flame-retardant baffle can be opened to facilitate airflow, ensuring that the mold steel can be cooled evenly during the annealing process and improving the annealing quality.

[0015] 3. By setting up a transmission mechanism such as a double-layer sprocket, synchronous chain, transmission sprocket, drive sprocket, gear, and rack, the unfolding and opening operation of the fire-resistant partition is more convenient and synchronized, improving the reliability of the device.

[0025] Please see Figure 1-2 This utility model provides a technical solution for a hanger device for heat treatment of mold steel:

[0026] A hanger device for heat treatment of mold steel includes a bottom support 1, with a support column 2 vertically fixedly connected to the top corner of the bottom support 1. The tops of multiple support columns 2 are fixedly connected by a top support 4. The bottom support 1 is used to support the entire device, and the support columns 2 serve to connect the bottom support 1 and the top support 4. All components in this solution are made of high-temperature resistant metal.

[0027] A top crossbeam 7 is fixedly installed in the middle of the top support 4. Multiple fire-resistant baffles 6 are rotatably connected between the top crossbeam 7 and the side wall of the top support 4. The fire-resistant baffles 6 can be made of high-temperature resistant materials, such as stainless steel plates, which can effectively block flames. The ends of the fire-resistant baffles 6 extend to the outside of the top support 4 and are fixedly connected to double-layer sprockets 3. Adjacent double-layer sprockets 3 are connected by a synchronous chain 5. Through the cooperation of the double-layer sprockets 3 and the synchronous chain 5, the synchronous rotation of multiple fire-resistant baffles 6 can be achieved.

[0028] One of the fire-resistant partitions 6 has a drive sprocket 10 installed at its head end. Side plates 13 are fixedly connected to both sides of the bottom end of the top crossbeam 7. A rotating shaft 15 is rotatably installed at the bottom end of the side plate 13. A drive sprocket 12 is fixedly connected to the end of the rotating shaft 15. The drive sprocket 12 and the drive sprocket 10 are connected by a drive chain 11. When the rotating shaft 15 rotates, the corresponding fire-resistant partition 6 can be rotated through the drive sprocket 12, the drive chain 11 and the drive sprocket 10. In turn, the other fire-resistant partitions 6 can be rotated synchronously through the double-layer sprocket 3 and the synchronous chain 5.

[0029] A sliding rod 8 is slidably installed in the middle of the top crossbeam 7. A blocking ring 16 is fixedly connected to the bottom end of the sliding rod 8, and a lifting ring 9 is fixedly connected to the top end. The lifting ring 9 is used to connect with lifting equipment, which drives the entire device to rise and fall. The blocking ring 16 is elastically connected to the bottom end of the top crossbeam 7 by a spring 17. A gear is fixedly installed at the bottom end of the blocking ring 16, and a gear 14 is fixedly installed in the middle of the rotating shaft 15. The gear 14 meshes with the gear. When the lifting equipment pulls the sliding rod 8 upward through the lifting ring 9, the sliding rod 8 drives the blocking ring 16 to move upward, the spring 17 is compressed, the gear on the blocking ring 16 drives the gear 14 to rotate, the gear 14 drives the rotating shaft 15 to rotate, and then drives the fire-arresting baffle 6 to unfold through the transmission mechanism. When the device is lowered, the lifting ring 9 does not generate an upward pulling force. Under the elastic force of the spring 17, the blocking ring 16 moves downward, the gear drives the gear 14 to rotate in the opposite direction, thereby driving the fire-arresting baffle 6 to open.

[0030] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
