Technical Field

[0001] The utility model relates to the technical field of heat treatment of circular knitting machine needles, in particular to a heat treatment device for circular knitting machine needles. Background Art

[0002] The circular knitting needle quenching heat treatment device is a device used to perform quenching heat treatment on circular knitting needles. In the manufacturing industry, especially in the field of metal processing and manufacturing, quenching is a common heat treatment method used to improve the hardness and strength of metals. In the heating device, the circular knitting needle is heated to a certain temperature to reach the required quenching temperature. Then, the circular knitting needle is rapidly cooled to form a quenched structure on its surface to improve its hardness and strength.

[0003] In traditional circular knitting machine needle heat treatment devices, the workpiece can only be processed in one direction at a time. The high-frequency induction coil needs to return to its initial position after moving and heating. Before it returns to its initial position, the next group of workpieces cannot be processed. This will cause the equipment to be idle while waiting for the high-frequency induction coil to return to its initial position, reducing the utilization rate and production efficiency of the equipment.

[0004] To this end, we propose a circular knitting machine needle heat treatment device. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1: A circular knitting machine needle heat treatment device, such as Figure 1As shown, it includes a base 1, a track 2 is vertically connected to the upper edge of the base 1, a wastewater collection tank 4 is arranged at the upper end of the base 1, a rotating frame 3 which is driven by a waterproof stepping motor to realize the rotation of a specified angle is arranged in the middle position of the wastewater collection tank 4, a plurality of groups of circular machine needles 5 are vertically connected to the edge of the rotating frame 3, and a heat treatment component 6 which is repeatedly moved up and down to heat the circular machine needles 5 to realize heat treatment is arranged on the front side of the track 2, and the up and down one-way moving distance of the heat treatment component 6 is greater than the length of the circular machine needles 5.

[0028] When in use, a worker stands on the opposite side of the track 2 and places the circular machine needles 5 that need to be heat treated on the rotating frame 3. The rotating frame 3 rotates at a specified angle to bring the circular machine needles 5 to the side corresponding to the position of the heat treatment component 6. At this time, the rotating frame 3 stops rotating and the heat treatment component 6 moves from bottom to top to heat the circular machine needles 5. When the heat treatment component 6 moves to the top of the track 2, the rotating frame 3 rotates at a specified angle to move the next group of circular machine needles 5 to the position corresponding to the heat treatment component 6. The heat treatment component 6 moves from top to bottom to heat the circular machine needles 5, and so on. When the processed circular machine needles 5 rotate to the worker's position, they are removed and new circular machine needles 5 that need to be processed are placed.

[0029] This design can realize heat treatment processing while loading and unloading materials, and multi-station rotation operation. The heat treatment component 6 does not need to wait for it to return to the initial position after moving upward. The heat treatment component 6 can also be processed during the return process, realizing two-way processing, minimizing the idle time of the equipment, improving equipment utilization, and improving production efficiency.

[0030] Embodiment 2: Based on the above embodiment, Figure 2 As shown, the heat treatment component 6 includes a slider 61 that is slidably connected to the track 2. The front side of the slider 61 is fixedly connected to the support platform 62. The front side of the support platform 62 is connected to a high-frequency induction coil 63. The high-frequency induction coil 63 is in a shape that surrounds both sides of the circular knitting needle 5. The front end of the high-frequency induction coil 63 is open to avoid interference with the fixed position of the circular knitting needle 5 when moving.

[0031] Among them, cooling components 7 are provided on the upper and lower sides of the support platform 62. When the high-frequency induction coil 63 moves upward, the cooling component 7 at the lower end cools the high-temperature circular machine needle 5. When the high-frequency induction coil 63 moves downward, the cooling component 7 at the upper end cools the high-temperature circular machine needle 5.

[0032] Embodiment 3: Based on the above embodiment, Figure 3As shown, the cooling assembly 7 includes a water pipe 71, which is a U-shaped hollow pipe.

[0034] Among them, when the lifting motor 8 rotates forward, it drives the winding wheel 9 to rotate and reel in the lifting rope 10. The reeling of the lifting rope 10 then pulls the slider 61 upward to move it up. When the lifting motor 8 rotates reversely, it drives the winding wheel 9 to rotate and release the lifting rope 10. The release of the lifting rope 10 causes the slider 61 to move downward.

[0035] Embodiment 5: Based on the above embodiment, Figure 5 and Figure 6 As shown, the rotating frame 3 includes an upper support rod 31 installed at the top edge of the main rotating frame 3 and a lower connecting rod 33 installed at the bottom edge of the main rotating frame 3. The number of the upper support rod 31 and the lower connecting rod 33 are the same, and the upper and lower positions of the upper support rod 31 and the lower connecting rod 33 correspond vertically. The end of the upper support rod 31 is connected to a hook 32, and the hook 32 is hooked with the top of the circular machine needle 5. The end face of the lower connecting rod 33 is connected to a limit block 34, and the limit block 34 limits the positions of the bottom sides of the circular machine needle 5.

[0036] Among them, the hook 32 is hooked with the top of the circular knitting needle 5. This connection method is convenient for workers to load and unload materials, and the contact area between the hook 32 and the circular knitting needle 5 is small, which does not affect its heat treatment. The limit block 34 limits and fixes the bottom of the circular knitting needle 5 to prevent the circular knitting needle 5 from swinging when moving and interfering with the heat treatment component 6.
