Description

Technical Field

[0001] The utility model relates to the technical field of wire production, in particular to a salt bath quenching tank for spring steel wire. Background Art

[0002] Salt bath quenching aims to leverage the high thermal conductivity and uniform heat distribution of the salt bath, allowing the spring steel wire to quickly reach the quenching temperature, thereby reducing the heating time. Furthermore, the short heating period also helps maintain the fine grain structure within the wire, thereby improving the wire's toughness. Existing quenching tanks, which hold the salt bath, are typically left with their top openings exposed during quenching. Due to the relatively high temperatures within the quenching tank, this exposed opening increases the risk of heat medium escaping, thereby reducing worker safety. Therefore, there is a need for a new salt bath quenching tank for spring steel wire that addresses these technical issues. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a spring steel wire salt bath quenching tank.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figures 1 to 5 The embodiment of the present invention provides a spring steel wire salt bath quenching tank, which includes: a frame 1, a salt bath tank 2 is provided in the frame 1, and a protective component 3 is provided on the top of the salt bath tank 2.

[0024] In the embodiments of the present invention, please refer to Figures 1 to 5 The protective component 3 includes a support ring 31, and the inner wall of the support ring 31 is provided with a number of evenly distributed connecting teeth a311, and an annular groove 312 is provided on the side of the support ring 31 away from the connecting teeth a311. A fixedly connected fixing bar 32 is provided on one side of the support ring 31, and a sliding rod 331 is provided in a sliding connection inside the annular groove 312. A fixedly connected moving bar 33 is provided at the end of the sliding rod 331, and a telescopic protective cover 34 is provided between the moving bar 33 and the fixed bar 32; a driving motor a35 is provided on the outer wall of the moving bar 33, and a driving gear a351 is provided at the output end of the driving motor a35, and the driving gear a351 is meshed with the connecting teeth a311.

[0025] It should be noted that: through the setting of the protective component 3, in the later use process, when the external suspension device places the spring steel wire to be quenched inside the salt bath tank 2, the movable bar 33 can be controlled to drive the telescopic protective cover 34 to move, so that the top of the salt bath tank 2 can be sealed to a certain extent, reducing the diffusion area of ​​the heat source inside the salt bath tank 2 to the outside, thereby improving the work experience of the staff and, at the same time, reducing the phenomenon of accidental injury to the staff due to the splashing of debris and other impurities during the quenching process.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 5 A ring guide rail 5 is provided on the top of the salt bath tank 2, and a linkage assembly 4 is provided inside the salt bath tank 2. The linkage assembly 4 includes a support frame 41. The outer side of the top of the support frame 41 is abutted against and slidably connected to the inner wall of the ring guide rail 5, and the outer wall of the support frame 41 is abutted against and slidably connected to the outer wall of the salt bath tank 2. A support rod 42 is provided inside the support frame 41, and a number of evenly distributed blades 421 are provided on the outside of the support rod 42.

[0027] It should be noted that: by setting up the blades 421 inside the support frame 41, when in use, the rotating support frame 41 will drive the blades 421 to stir and mix the salt solution inside the salt bath tank 2, thereby making the temperature of the salt solution more uniform, reducing the impact of uneven salt solution temperature on the quenching of the spring steel wire;

[0028] Since the outer wall of the support frame 41 is against the inner wall of the salt bath tank 2, when the salt solution is discharged outward and the inner wall of the salt bath tank 2 is cleaned, the rotating support frame 41 can assist in scraping the inner wall of the salt bath tank 2, thereby making it more convenient for the staff to clean the salt bath tank 2.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 5 A fixedly connected annular bar 43 is provided on the support frame 41, and a plurality of evenly distributed connecting teeth b431 are provided on the top of the annular guide rail 5. A driving motor b44 is provided on the top of the driving motor b44. A driving gear b441 is provided at the output end of the driving motor b44, and the outer wall of the driving gear b441 is meshed with the connecting teeth b431.

[0030] It should be noted that: through the engagement between the driving gear b441 and the connecting gear b431, when the driving motor b44 is working, the annular bar 43 can be stably driven, and the rotation of the annular bar 43 will drive the support frame 41 to rotate inside the annular guide rail 5.

[0031] The working principle of the spring steel wire salt bath quenching tank provided by the utility model is as follows;

[0032] When using the device, the staff can control the external suspension component to move the spring steel wire to be quenched into the salt bath tank 2, and then control the drive motor a35 to rotate, and the rotating drive motor a35 will drive the drive gear a351 to rotate;

[0033] The rotating driving gear a351 will drive the moving bar 33 to move in the annular groove 312 through the inner core of the connecting tooth a311, and the moving moving bar 33 will pull one end of the telescopic protective cover 34, so that the telescopic protective cover 34 can be unfolded on the top of the salt bath tank 2 until the outer wall of the moving bar 33 abuts against the outer wall of the fixed bar 32, thereby realizing the shielding of the top of the salt bath tank 2, thereby reducing the outward diffusion of the internal temperature of the salt bath tank 2 during the quenching process, thereby improving the comfort of the working environment of the surrounding staff, and also reducing the phenomenon of accidental injury to the staff caused by the outward splashing of debris and other impurities during the quenching process;

[0034] During the quenching process, the driving motor b44 can also be controlled to drive the driving gear b441 to rotate. The rotating driving gear b441 will drive the annular bar 43 to rotate inside the annular guide rail 5 through the engagement with the connecting gear b431, thereby driving the support frame 41 to rotate synchronously. During the rotation of the support frame 41, the support rod 42 located on the support frame 41 will stir and mix the salt solution through the blades 421 on the outer wall, thereby making the temperature inside the salt bath tank 2 more uniform, thereby helping to improve the quenching effect of the spring steel wire.

[0035] After the quenching of the spring steel wire is completed and the salt solution is discharged outward, the drive motor b44 can be controlled to work again to drive the support frame 41 to rotate, and the outer wall of the rotating support frame 41 can be scraped off the residue on the inner wall of the salt bath tank 2 by contacting the inner wall thereof, thereby facilitating the cleaning of the device by the staff.

[0036] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0037] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
