Description

Technical Field

[0001] This utility model relates to the field of annealing equipment, and more particularly to a roll annealing equipment. Background Technology

[0002] The main working parts and tools on a rolling mill that cause continuous plastic deformation of metals are the rolls. The rolls are mainly composed of three parts: the roll body, the roll neck, and the shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. Annealing is a metal heat treatment process that refers to slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and crack tendency, refine grains, adjust the microstructure, and eliminate microstructural defects. To be precise, annealing is a heat treatment process for materials, including metallic and non-metallic materials. Moreover, the annealing purpose of new materials also has similarities and differences from that of traditional metal annealing.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In actual operation, most existing annealing devices typically use the method of placing the rolls directly inside the device for annealing. However, this design often makes it difficult to ensure that the rolls are heated evenly during the annealing process. This is because the distribution of heat inside the device may be affected by various factors, such as the layout of the heating elements, the state of airflow, and the shape and size of the rolls themselves. This leads to temperature differences in different parts of the rolls, which in turn reduces the annealing effect and affects the performance and service life of the rolls. Utility Model Content

This is because the heat distribution inside the device can be affected by various factors, such as the layout of the heating elements, the state of airflow, and the shape and size of the rolls themselves. This results in temperature differences in different parts of the rolls, which in turn reduces the annealing effect and affects the performance and service life of the rolls.

The height of the heating frame 304 can be adjusted by starting the cylinder 301.

[0039] Example 2:

[0040] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: the limiting component 3 includes a cylinder 301 fixed to the inner wall of the housing 201, and a ring 302 is sleeved on the bottom surface of the cylinder 301. A sleeve 303 is fixed on the surface of the ring 302, and a heating frame 304 is fixed on the surface of the ring 302. A heat-concentrating cover 305 is fixed on the surface of the heating frame 304, and a heater 306 is fixed on the side surface of the heating frame 304.

[0041] like Figure 1-5 As shown, multiple sets of heaters 306 are provided, and the heaters 306 are arranged in a ring, which can make the rolls heat evenly. The height of the heating frame 304 can be adjusted by starting the cylinder 301.

[0042] like Figure 1-5 As shown, the sleeve 303 has a groove 307 on its surface and a spring 308 inside. A protrusion 309 is movably connected inside the sleeve 303, and a limit post 310 is fixed on the surface of the protrusion 309.

By sliding the ring 302 and the heating frame 304, the heating frame 304 can be disassembled. Similarly, it is more convenient to install and disassemble the heating frame 304.

[0045] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0046] 1. The rotating assembly 2 is equipped with a servo motor 216 and a lead screw 219. When the user starts the servo motor 216, the servo motor 216 can drive the lead screw 204 to rotate, thereby causing the lead screw 204 to drive the nut seat 205 to slide. The nut seat 205 drives the sliding member 206 and the sliding column 208 to slide, which is convenient for clamping rolls of different lengths. The lead screw 219 can drive the nut seat 220 to slide, and the nut seat 220 can drive the clamping block 221 to slide, which can clamp rolls of different diameters.

By sliding the ring 302 and the heating frame 304, the heating frame 304 can be disassembled.

[0048] In this technical solution, when clamping the roll, the servo motor 216 is activated. The servo motor 216 drives the lead screw 204 to rotate, thereby causing the lead screw 204 to slide the nut seat 205. The nut seat 205 then drives the sliding member 206 and the sliding column 208 to slide. The distance between the two sets of sliding members 206 and sliding column 208 can be adjusted according to the length of the roll. The surface of the sliding column 208 is provided with a concave block 212 and a lead screw 219. By rotating the lead screw 219, the lead screw 219 can drive the nut seat 220 to slide, which in turn drives the clamping block 221 to slide, thus clamping rolls of different diameters. The roller, by rotating the extension shaft 211, can drive the concave block 212 and the circular block 213 to rotate, which facilitates the rotation of the roller and improves the heating effect. The heater 306 is provided in multiple sets and is arranged in a ring, which can make the roller heat evenly. By starting the cylinder 301, the height of the heating frame 304 can be adjusted. When the heating frame 304 needs to be disassembled, the sliding limit post 310 can drive the protrusion 309 to slide, thereby separating the protrusion 309 from the cylinder 301. By sliding the ring 302 and the heating frame 304, the heating frame 304 can be disassembled. Similarly, the installation and disassembly of the heating frame 304 are more convenient.
