Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled steel ball processing, and particularly relates to a surface tempering device for hot-rolled steel balls. Background Technique

[0002] Hot-rolled steel balls are a brand-new rolling process technology and a breakthrough in the process technology of the ball mill ball manufacturing industry. After the steel balls are just produced, in order to eliminate or reduce internal stress, reduce brittleness, and prevent deformation and cracking, a tempering device is often used to temper these steel balls.

[0003] After retrieval, a utility model with the Chinese patent publication number CN213977819U discloses a steel ball tempering device, which includes a tempering furnace with heating pipes inside. A placement rack for placing steel balls is arranged in the tempering furnace. The steel ball tempering device also includes a driving motor with an output shaft extending upwards. The output shaft is used to connect to the placement rack or be in transmission cooperation with the placement rack to drive the placement rack to rotate in the tempering furnace, and the output shaft is connected or in transmission cooperation with the placement rack.

[0004] Since the temperature of the steel balls is relatively high after being heated in the tempering furnace, after the heating is completed, it is necessary to wait until the temperature of the steel balls drops before they can be taken, otherwise it is easy to cause burns, and the operation is relatively inconvenient, affecting the processing efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a surface tempering device for hot-rolled steel balls to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A surface tempering device for hot-rolled steel balls includes a bottom plate. A placement component is installed on the top of the bottom plate. The placement component includes a rotating disk rotatably connected to the outer wall of the top of the bottom plate. A toothed ring is fixedly sleeved on the circumferential outer wall of the rotating disk. A second motor is fixedly installed on the outer wall of the top of the bottom plate. A gear is coaxially fixed to the rotating shaft of the second motor. The gear meshes with the toothed ring. An installation frame is coaxially fixed to the outer wall of the top of the rotating disk. The middle parts of the inner walls on both sides of the installation frame are rotatably connected to the same bidirectional lead screw. Threaded connections are made at both ends of the bidirectional lead screw with an installation block, and both installation blocks are in contact with the inner wall of the installation frame.

[0007] As a further preferred of this technical solution, two limiting rods are fixedly connected to the inner walls on both sides of the installation frame.

[0012] As a further preference of this technical solution, the two mounting covers are made of heat-insulating materials as a whole.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0022] The utility model provides a technical solution: as Figure 2 , Figure 3As shown in FIGS. 4, in this embodiment, a surface tempering device for hot-rolled steel balls includes a bottom plate 1, and is characterized in that: a placing component 7 is installed on the top of the bottom plate 1. The placing component 7 includes a rotating disk 707 rotatably connected to the outer wall of the top of the bottom plate 1. A toothed ring 708 is fixedly sleeved on the circumferential outer wall of the rotating disk 707. A second motor 709 is fixedly installed on the outer wall of the top of the bottom plate 1. A gear 710 is coaxially fixed to the rotating shaft of the second motor 709. The gear 710 meshes with the toothed ring 708. An installation frame 701 is coaxially fixed to the outer wall of the top of the rotating disk 707. The middle parts of the inner walls on both sides of the installation frame 701 are rotatably connected to the same bidirectional lead screw 703. Threaded connections are made at both ends of the bidirectional lead screw 703 with a mounting block 702, and both mounting blocks 702 are in contact with the inner wall of the installation frame 701.

[0023] Two limiting rods 704 are fixedly connected to the inner walls on both sides of the installation frame 701. Both mounting blocks 702 are sleeved outside the two limiting rods 704. A first motor 705 is fixedly installed inside the installation frame 701. The rotating shaft of the first motor 705 is coaxially fixed to one end of the bidirectional lead screw 703. A mounting cover 706 is fixedly connected to the outer wall of the top of both mounting blocks 702, and the two mounting covers 706 are symmetrically arranged.

[0024] Start the first motor 705 inside the installation frame 701. The rotating shaft of the first motor 705 drives the bidirectional lead screw 703 to rotate. The two mounting blocks 702 sleeved outside the two limiting rods 704 will be driven by the bidirectional lead screw 703 to approach each other. The mounting cover 706 inside the tempering furnace body 2 will be driven by the mounting block 702 to break away. Subsequently, start the second motor 709 on the top of the bottom plate 1. The rotating shaft of the second motor 709 drives the gear 710 to rotate. The gear 710 can drive the rotating disk 707 to rotate half a circle on the top of the bottom plate 1 through the toothed ring 708 meshing with it. The installation frame 701 will also be driven by the rotating disk 707 to rotate synchronously. The positions of the two mounting covers 706 will also be swapped. Finally, drive the mounting blocks 702 to move away from each other again. The mounting cover 706 filled with new hot-rolled steel balls will enter the tempering furnace body 2. At this time, processing can continue, and the steel balls with higher temperature will also be exposed to the external environment, having enough time to be processed.

[0025] As Figure 1 shown, a tempering furnace body 2 is fixedly installed on one side of the outer wall of the top of the bottom plate 1. An opening 3 is provided outside the tempering furnace body 2. The mounting cover 706 can enter the opening 3 and form a complete closed space with the tempering furnace body 2.

[0026] As Figure 1As shown, the inner walls of the bottoms of two mounting covers 706 are rotatably connected to a mounting shaft 4. A plurality of evenly distributed holding frames 5 are fixedly sleeved outside the mounting shaft 4. A motor is installed inside the mounting cover 706, and the rotating shaft of the driving motor is coaxially fixed to the mounting shaft 4. Placing the steel balls in the plurality of holding frames 5 can ensure that they are heated evenly enough, and the motor drives the mounting shaft 4 and the holding frames 5 to rotate, thereby further increasing the heating effect.

[0027] As Figure 1 shown, on the other side of the top outer wall of the bottom plate 1, a support plate 6 is fixedly connected. The mounting cover 706 can be exactly located on top of the support plate 6, which can support the mounting cover 706 outside, thereby avoiding excessive stress on the mounting block 702 caused by the suspension of the mounting cover 706.

[0028] As Figure 1 shown in and Figure 2, the two mounting covers 706 are made of heat-insulating materials as a whole to prevent the heat emitted by the tempering furnace body 2 from escaping to the outside.

[0029] As Figure 3 shown, the transmission ratio between the gear 710 and the toothed ring 708 is greater than one. The gear 710 rotates multiple turns before driving the toothed ring 708 to rotate one turn, which is beneficial to reducing the load on the motor two 709.

[0030] The present utility model provides a surface tempering device for hot-rolled steel balls, and the specific working principle is as follows:

[0031] When the device is working, after a batch of steel balls inside the tempering furnace body 2 complete the tempering process, the motor one 705 inside the mounting frame 701 is started. The rotating shaft of the motor one 705 drives the bidirectional lead screw 703 to rotate. The two mounting blocks 702 sleeved outside the two limit rods 704 will be driven by the bidirectional lead screw 703 to approach each other. The mounting cover 706 inside the tempering furnace body 2 will be driven by the mounting block 702 to move out. Subsequently, the motor two 709 on top of the bottom plate 1 is started. The rotating shaft of the motor two 709 drives the gear 710 to rotate. The gear 710 can drive the rotating disk 707 to rotate half a circle on top of the bottom plate 1 through the toothed ring 708 meshing with it. The mounting frame 701 will also be driven by the rotating disk 707 to rotate synchronously. The positions of the two mounting covers 706 will be swapped. Finally, the mounting blocks 702 are driven to move away from each other again. The mounting cover 706 filled with new hot-rolled steel balls will enter the tempering furnace body 2. At this time, processing can continue, and the steel balls with higher temperature will also be exposed to the external environment, having enough time to be processed.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
