Description

Technical Field

[0001] This utility model relates to the field of textile machinery parts manufacturing technology, and in particular to a heat treatment device for strengthening and toughening heddles. Background Technology

[0002] Heddle wires are thin, elongated metal sheets or threads used on a loom to guide the warp yarns through. They are usually made of steel or other high-strength alloys. Because they need to be bent and recovered frequently during the weaving process and are not easy to break, they require high strength, hardness, and toughness. Therefore, heat treatment is required during the production stage, which involves heating and then cooling to change the internal microstructure of the material and enhance its toughness and strength.

[0003] Existing methods for strengthening and toughening heddles typically involve directly heating the material surface. This process usually takes place in an exposed environment or a large space. Because heat energy rapidly diffuses and dissipates into the surrounding environment, the temperature cannot be precisely controlled, making it difficult to maintain a uniform temperature on the material surface. This uneven heating distribution affects the heat treatment effect, leading to unstable material properties of the heddles. Furthermore, because a certain amount of heat needs to be maintained in the space, more heat energy needs to be added, resulting in a waste of energy.

[0004] Therefore, in view of the existing heat treatment method that directly heats the surface of the heddle wire material in a large space, the heat energy diffuses to the surroundings, resulting in inaccurate temperature control, uneven heating of the material, affecting the heat treatment effect, unstable material properties of the heddle wire, and serious heat loss in the space, causing energy waste, a heat treatment device with a relatively closed heat treatment process can be designed. Utility Model Content

[0005] In order to overcome the problems of existing heat treatment methods that directly heat the surface of heddle wire in a large space, heat energy diffuses to all sides, resulting in inaccurate temperature control, uneven heating of the material, affecting the heat treatment effect, unstable material properties of heddle wire, and serious heat loss in the space, resulting in energy waste.

[0006] The technical solution of this utility model is as follows: a heat treatment device for strengthening and toughening heddles, including a base; and a heating treatment cylinder. Six support columns are symmetrically fixedly connected to the upper left side of the base. The heating treatment cylinder is fixedly connected to the end of each support column away from the base. The bottom and left and right sides of the heating treatment cylinder are connected to the outside. A controller is fixedly connected to the top center of the heating treatment cylinder. A heating resistance wire electrically connected to the controller is provided on the inner wall surface of the heating treatment cylinder. A groove is opened in the middle of the upper end of the base. A movable plate is slidably arranged inside the groove. The upper end of the movable plate passes through... A heat insulation platform is fixedly connected to the groove. Mounting plates are symmetrically fixedly connected to the upper left and right sides of the heat insulation platform. An N-shaped plate is symmetrically connected to the two mounting plates at their relatively close ends via a rotating shaft. A heat insulation plate is symmetrically fixedly connected to the two N-shaped plates at their relatively close ends. A fixed clamping block is symmetrically fixedly connected to the lower side of the two heat insulation plates at their relatively close ends. A movable clamping block is symmetrically and movably installed on the upper side of the two heat insulation plates at their relatively close ends. Heat insulation blocks with arc-shaped grooves on their upper sides are symmetrically fixedly connected to the upper left and right sides of the heat insulation platform, and the two heat insulation blocks are respectively located on the lower side of the two heat insulation plates.

[0007] Preferably, the heat insulation table is first moved to the right side above the base, and the two ends of the workpiece are placed on the upper ends of the two fixed clamping blocks. The workpiece is then fixed by pressing down the moving clamping block. Next, the heat insulation table is moved back to the inside of the heat treatment cylinder. At this time, the heat insulation table blocks the bottom opening of the heat treatment cylinder. The heat insulation plates on both sides and the corresponding heat insulation blocks are combined to block the left and right openings of the heat treatment cylinder, forming a small sealed space inside. The heating resistance wire is controlled by the controller to heat the workpiece. The heat generated is quickly and evenly distributed inside the heat treatment cylinder. The two N-shaped plates are controlled to drive the two heat insulation plates to rotate continuously, further improving the uniformity of heating on the surface of the workpiece. After heating is completed, the heat insulation table is moved to the outside to cool the workpiece exposed to the air, thus completing the entire heat treatment process.

[0008] Preferably, a temperature sensor electrically connected to the controller is fixedly connected to the top inner side of the heating cylinder, and the temperature sensor is of model CWDZ.

[0009] Preferably, a rotating motor electrically connected to the controller is fixedly connected to the right side of the mounting plate, and the output shaft of the rotating motor is fixedly connected to the rotating shaft of the right N-shaped plate.

[0010] Preferably, four connecting rods are evenly fixed between the two heat insulation plates, the rotation centers of the two heat insulation plates and the two N-shaped plates are set on the same axis, and the combination of heat insulation plates and heat insulation blocks is set with the same shape and size as the mounting plate.

[0011] Preferably, the heat insulation plate has a vertical through groove in the middle, and a connecting plate is installed through the through groove. One end of the connecting plate is fixedly connected to the corresponding moving clamp block.

[0012] Preferably, a lifting block is fixedly connected to the other end of the connecting plate, a threaded column is rotatably connected to the inner side of the N-shaped plate, the lifting block is threadedly connected to the outer side of the threaded column, and a knob is rotatably connected to the bottom of the N-shaped plate.

[0014] The beneficial effects of this utility model are:

[0015] This device features a heating treatment cylinder for heating workpieces located on the upper left side of the base. A freely movable heat-insulating platform is used to transport the workpieces. Two heat-insulating plates are mounted on the heat-insulating platform, with fixed and movable clamping blocks on the plates to hold and fix the workpieces. During the heating process, the two heat-insulating plates, together with the heat-insulating platform and the two heat-insulating blocks, seal the bottom and left and right openings of the heating treatment cylinder, thus forming a relatively small and enclosed heating zone. This facilitates temperature control. Combined with the rotation of the workpiece, the surface of the workpiece can be heated quickly and evenly, resulting in a relatively ideal heating effect, a better heat treatment process, improved workpiece strength and toughness, and improved product quality. Furthermore, the small space requires less heat, and heat loss is not easily prevented, thus saving energy. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-7This utility model provides an embodiment of a heat treatment device for strengthening and toughening heddles, including a base 1 and a heating treatment cylinder 5. Six support columns 13 are symmetrically fixedly connected to the upper left side of the base 1. The ends of the support columns 13 away from the base 1 are all fixedly connected to the heating treatment cylinder 5. The bottom and left and right sides of the heating treatment cylinder 5 are connected to the outside. A controller 14 is fixedly connected to the top center of the heating treatment cylinder 5. Heating resistance wires 6 electrically connected to the controller 14 are provided on the inner wall surface of the heating treatment cylinder 5. A groove 2 is opened in the middle of the upper end of the base 1. A movable plate 3 is slidably arranged inside the groove 2. The upper end of the movable plate 3 extends out of the groove 2 and is fixedly connected to a heat insulation platform. 4. Mounting plates 7 are symmetrically fixedly connected to the upper left and right sides of the heat insulation table 4. An N-shaped plate 8 is symmetrically connected to the relatively close ends of the two mounting plates 7 via a rotating shaft. Heat insulation plates 9 are symmetrically fixedly connected to the relatively close ends of the two N-shaped plates 8. Fixed clamping blocks 10 are symmetrically fixedly connected to the lower sides of the relatively close ends of the two heat insulation plates 9. Movable clamping blocks 11 are symmetrically and movably arranged on the upper sides of the relatively close ends of the two heat insulation plates 9. Heat insulation blocks 12 with arc-shaped grooves on their upper sides are symmetrically fixedly connected to the upper left and right sides of the heat insulation table 4. The two heat insulation blocks 12 are respectively located below the two heat insulation plates 9. First, move the heat insulation table 4 to the right side above the base 1, and then place both ends of the workpiece on the two fixed clamping blocks 10. The workpiece is fixed at the upper end by pressing down the clamping block 11. Then, the heat insulation table 4 is moved back to the inside of the heat treatment cylinder 5. At this time, the heat insulation table 4 seals the bottom opening of the heat treatment cylinder 5. The heat insulation plates 9 on both sides and the corresponding heat insulation blocks 12 combine to seal the left and right openings of the heat treatment cylinder 5, forming a small sealed space inside. The heating resistance wire 6 is controlled by the controller 14 to heat, and the generated heat is quickly and evenly distributed inside the heat treatment cylinder 5. The two N-shaped plates 8 are controlled to drive the two heat insulation plates 9 to rotate continuously, further improving the uniformity of the workpiece surface heating. After heating is completed, the heat insulation table 4 is moved to the outside to cool the workpiece exposed to the air, completing the heat treatment process. In this process, a temperature sensor 15, electrically connected to the controller 14, is fixedly connected to the top inner side of the heating treatment cylinder 5. The temperature sensor 15 is a CWDZ11 model. The temperature sensor 15 monitors the internal temperature and helps the controller 14 control the operation of the heating resistance wire 6 to maintain a constant internal temperature of the heating treatment cylinder 5. A rotary motor 16, electrically connected to the controller 14, is fixedly connected to the right side of the mounting plate 7. The output shaft of the rotary motor 16 is fixedly connected to the rotating shaft of the right N-shaped plate 8. The controller 14 controls the operation of the rotary motor 16, which drives the two N-shaped plates 8 and the heat insulation plate 9 to rotate, controlling the workpiece to rotate and be heated evenly.

[0026] Please see Figures 1-3 and Figures 5-6In this embodiment, four connecting rods 17 are evenly and fixedly connected between the two heat insulation plates 9. The rotation centers of the two heat insulation plates 9 and the two N-shaped plates 8 are set on the same axis. The combination of the heat insulation plate 9 and the heat insulation block 12 is set with the same shape and size as the mounting plate 7. The four connecting rods 17 strengthen the connection between the two heat insulation plates 9. The rotation centers of the heat insulation plate 9 and the N-shaped plates 8 are coaxial, which can keep the workpiece rotating smoothly. The combination of the heat insulation plate 9 and the heat insulation block 12 is the same shape and size as the mounting plate 7, which can keep the mounting plate 7 moving normally through the left and right openings of the heat treatment cylinder 5. A vertical through groove 18 is opened in the middle of the heat insulation plate 9. A connecting plate 19 is installed through the through groove 18. One end of the connecting plate 19 is fixedly connected to the corresponding movable clamping block 11. By moving the connecting plate 19 downward, the movable clamping block 11 can be pushed downward, thereby pressing and fixing the workpiece. The other end of 9 is fixedly connected to a lifting block 20. The inner side of the N-shaped plate 8 is rotatably connected to a threaded column 21. The lifting block 20 is threadedly connected to the outer side of the threaded column 21. The bottom of the N-shaped plate 8 is rotatably connected to a knob 22. The knob 22 is fixedly connected to the threaded column 21 through a connecting shaft. Rotating the knob 22 drives the threaded column 21 to rotate. The threaded column 21 drives the lifting block 20 to move down, thereby pushing the connecting plate 19 and the moving clamp block 11 to move down. The inner side of the groove 2 is rotatably connected to a threaded rod 23. The moving plate 3 is threadedly connected to the outer side of the threaded rod 23. The right end of the base 1 is fixedly connected to a moving motor 24 electrically connected to a controller 14. The output shaft of the moving motor 24 is fixedly connected to the threaded rod 23. The controller 14 controls the moving motor 24 to work, driving the threaded rod 23 to rotate. The threaded rod 23 pushes the moving plate 3 to move left and right, thereby adjusting the left and right position of the heat insulation table 4.

[0027] During operation, the controller 14 first controls the moving motor 24 to rotate the threaded rod 23. The threaded rod 23 pushes the moving plate 3 to move to the right, thereby adjusting the heat insulation table 4 to move to the right side above the base 1. The two ends of the workpiece are placed on the upper ends of the two fixed clamping blocks 10. The knob 22 is turned to rotate the threaded column 21, which drives the lifting block 20 to move down, thereby pushing the connecting plate 19 down. The moving clamping block 11 moves down and cooperates with the fixed clamping block 10 to fix and clamp the workpiece. Then, the heat insulation table 4 is moved back to the inside of the heat treatment cylinder 5. At this time, the heat insulation table 4 blocks the bottom opening of the heat treatment cylinder 5, and the two sides... The heat insulation plate 9 and the corresponding heat insulation block 12 are combined to seal the left and right openings of the heat treatment cylinder 5, forming a small sealed space inside. The heating resistance wire 6 is controlled by the controller 14 to heat the cylinder, and the generated heat is quickly and evenly distributed inside the heat treatment cylinder 5. The temperature sensor 15 detects the internal temperature and controls it to remain constant after heating to a certain temperature. The controller 14 also controls the rotating motor 16 to work. The rotating motor 16 drives the two N-shaped plates 8 and the heat insulation plate 9 to rotate, controlling the workpiece to rotate and be heated evenly. After heating is completed, the heat insulation table 4 is moved to the outside to cool the workpiece exposed to the air, completing the entire heat treatment process.

[0028] Through the above steps, a heating treatment cylinder 5 is set up for heating the workpiece, and a freely movable heat-insulating platform 4 is set up for transporting the workpiece. Two heat-insulating plates 9 are set on the heat-insulating platform 4, and fixed clamping blocks 10 and movable clamping blocks 11 are set on the heat-insulating plates 9 to clamp and fix the workpiece. During the heating process, the two heat-insulating plates 9, together with the heat-insulating platform 4 and the two heat-insulating blocks 12, seal the bottom and left and right side openings of the heating treatment cylinder 5, thereby forming a relatively small and enclosed heating zone, which facilitates temperature control and coordinates with the rotation of the workpiece. This method can quickly and evenly heat the surface of the workpiece, resulting in a relatively ideal heating effect and a better heat treatment process. It improves the strength and toughness of the workpiece, enhances product quality, and requires less heat in a small space, thus reducing heat loss and saving energy. This addresses the problems of existing heat treatment methods that directly heat the surface of heddle wire materials in a large space, where heat diffuses to the surroundings, leading to inaccurate temperature control, uneven heating distribution, and affecting the heat treatment effect. Furthermore, the material properties of the heddle wire are unstable, and significant heat loss within the space results in energy waste.
