DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-2 This utility model provides a technical solution: a device for precisely controlling the hardness uniformity of heat-treated materials. This device is designed to achieve high-precision control of material hardness, ensuring that the treated material possesses excellent mechanical properties and a consistent hardness distribution. The device primarily comprises a base plate 1, upon which a heat treatment chamber 2 is mounted. The interior of the heat treatment chamber 2 is sequentially arranged, from left to right, with a fixed frame 3, a support plate 4, and a slide rail 5, forming an orderly structure to support and ensure the smooth progress of the heat treatment process.

[0022] A first unloading bolt 6 is strategically mounted on the sidewall of the fixed frame 3. This bolt facilitates the unloading of the material from the chamber after heat treatment. Inside this bolt 6 is a first clamping plate 7, further inside which is a first turntable 8. Turntable 8 is not stationary but is driven by a small motor 9, enabling precise manipulation of the material. The motor 9 is mounted on the outer sidewall of the first clamping plate 7, ensuring stable driving force and facilitating maintenance.

[0023] The slide rail 5 slides the slider 10, which in turn is mounted on a movable frame 11. Mounted on this frame is a second unloading bolt 12, which functions similarly to the first unloading bolt 6. Inside this second unloading bolt 12 is a second clamping plate 13, which in turn is mounted inside this second clamping plate 13, which in turn is mounted on a second turntable 14. The movable frame 11 is driven by a telescopic cylinder 15, allowing for greater flexibility in the handling and placement of materials during the heat treatment process.

[0024] An infrared thermometer 16 is installed on the bottom of the heat treatment chamber 2 to monitor the material's heat treatment temperature in real time, ensuring accurate temperature control. A hot air blower 17 is located on the top of the heat treatment chamber 2, with a flat nozzle at its output end for evenly blowing hot air onto the material to achieve uniform hardness. Furthermore, an existing equipment controller 18 is designed on the side wall of the heat treatment chamber 2. This controller 18 plays a crucial role, establishing a close electrical connection with the infrared thermometer 16 and the hot air blower 17. This design allows the controller 18 to receive real-time temperature data measured by the infrared thermometer 16 and the operating status of the hot air blower 17. With this critical information, the controller 18 can precisely control the entire heat treatment process, ensuring that the temperature during the heat treatment process is always maintained within the ideal range, thereby ensuring high-quality heat treatment results. This precise control not only improves product qualification rate but also increases production efficiency, which is of great significance to the entire heat treatment industry. Through this design, it not only improves material processing quality but also increases production efficiency.

[0025] Specifically, a reinforcing plate is cleverly designed above the base plate 1. The reinforcing plate plays a role in strengthening the structure and ensuring the overall firmness and stability. The top part of the reinforcing plate is in close contact with the telescopic cylinder 15. This layout enables the telescopic cylinder to be well supported, enhancing the reliability and service life of the system. The fixing frame 3 adopts an L-shaped structural design, which is not only beautiful but also practical, providing greater stability and load-bearing capacity. In addition, reinforcing ribs are specially added at the intersection of the horizontal and vertical plates of the fixing frame. This detailed design further enhances the strength and rigidity of the structure, ensuring good performance and durability under various conditions of use. Such a design reflects the exquisite control of details in engineering design, as well as the high attention paid to structural integrity and safety of use.

[0026] Specifically, a first coil spring is installed between the fixing frame 3 and the first clamping plate. This spring not only acts as a shock absorber but also makes the connection between the two more flexible. Furthermore, this first coil spring is cleverly sheathed around the shaft of the first unloading bolt 6, making the entire structure more compact and improving its stability.

[0027] Similarly, a second coil spring is installed between the movable frame 11 and the second clamping plate 13, which also plays a role in shock absorption and flexible connection. Moreover, this second coil spring is also sleeved on the shaft of the second unloading bolt 12, which not only makes the entire structure more coordinated, but also increases its service life.

[0028] The design of these two sets of coil springs takes into account both structural stability and flexibility of use, fully reflecting the designer's wisdom and ingenuity.

[0029] Specifically, there are two support plates 4, which are parallel to each other and have smooth curved upper surfaces. A shaft-shaped part is designed on the upper side of the support plate 4 to increase its functionality. An infrared thermometer 16 is placed between the two support plates 4 for measuring temperature. The layout of the two support plates 4 and the infrared thermometer 16 is carefully designed to ensure the stability and measurement accuracy of the equipment. The object to be measured can be placed on the smooth curved surface of the support plate 4, and the temperature of the object to be measured can be obtained by measuring with the infrared thermometer 16. This design makes the measurement process more convenient and also improves the accuracy of the measurement.

[0030] Working principle: When the present invention is working, the heat treatment box 2 in the device is the main heating space. Hot air is blown into the heat treatment box through the hot air cylinder 17 to achieve heating treatment of the material. The infrared thermometer 16 monitors the temperature in the heat treatment box 2 in real time and feeds back the temperature data to the controller 18. The controller 18 dynamically adjusts the output power of the hot air cylinder 17 according to the preset temperature range and the actual temperature data fed back by the infrared thermometer 16, so as to accurately control the temperature in the heat treatment box 2. A fixed frame 3 and a movable frame 11 are provided in the heat treatment box 2, which clamp the material through the first clamping plate 7 and the second clamping plate 13 respectively. The turntable inside the first clamping plate 7 and the second clamping plate 13 is driven by the small motor 9 and the telescopic cylinder 15 to respectively realize the rotation and movement of the fixed and movable clamping plates to adapt to materials of different sizes and shapes.

[0031] The first coil spring and the second coil spring are respectively arranged between the fixed frame 3 and the first clamping plate 7 and between the movable frame 11 and the second clamping plate 13. Their function is to provide a certain buffer when clamping the material to ensure the stability and uniformity of the clamping.

[0032] The material to be processed is placed on the support plate 4, and the telescopic cylinder 15 pushes the movable frame 11 and the second clamping plate 13 to move toward the fixed frame 3 and the first clamping plate 7 until the material is clamped. The controller 18 starts the hot air cylinder 17 and blows hot air into the heat treatment box 2 through the flat nozzle to start the heating process. The infrared thermometer 16 monitors the temperature in the heat treatment box 2 in real time and adjusts the output power of the hot air cylinder 17 through the controller 18 to ensure that the temperature in the heat treatment box 2 is maintained within the preset range.

[0033] After the set heating time, the telescopic cylinder 15 retracts, and the movable frame 11 and the second clamping plate 13 release the material, facilitating the removal of the treated material. Through the synergistic effect of the above-mentioned temperature regulation and mechanical clamping, the device can achieve precise control of the material heat treatment process and ensure the uniformity of the material hardness.
