Description

Technical Field

[0001] This utility model relates to the field of cold rolling technology, and in particular to a stress relief device for stainless steel strip. Background Technology

[0002] Cold rolling is mainly used to improve the strength and hardness of steel, while also providing good surface finish and dimensional accuracy. It is widely used in manufacturing, construction, and automotive industries. Cold rolling refers to the process of further thinning hot-rolled steel coils to a target thickness at room temperature. Through cold rolling, the strength and hardness of steel are significantly improved, but the toughness and plasticity decrease. Therefore, cold-rolled products are usually used for parts with simple deformation. However, after a period of cold rolling, the surface of the rollers is prone to wear, affecting the surface quality of the strip and requiring maintenance and replacement. However, the rollers are large in size, making them difficult to position during replacement, wasting time and manpower. After replacement, the threaded connection pipeline is used, which is inconvenient and prone to wear or failure. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. After cold rolling for a period of time, the surface of the roller is prone to wear, which affects the surface quality of the strip and requires maintenance and replacement. However, the roller is large in size and difficult to position during replacement, wasting time and manpower. After replacement, the threaded connection pipeline is prone to wear or failure. This invention provides a stress relief device for stainless steel strip.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features grooves at both ends of the working roller and a positioning block placed between the upper and lower working rollers to reduce the time required to change the working rollers. Through the cooperation of the clamp and the protrusion, the spring is limited between the two. Pulling the clamp compresses the spring, slides the tube head to the protrusion, and moves the iron ball outward. Releasing the clamp releases the spring, and the clamp squeezes the iron ball inward, locking the iron ball in the groove of the tube head. This allows for quick replacement of the tube head. The clamping method ensures efficient and convenient pipeline connection and prevents wear or detachment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a stress relief device for stainless steel strip, including a main body 1, a sliding bracket 11 fixedly connected inside the main body 1, a roller 12 rotatably connected to the side of the main body 1, a conveyor belt 13 rotatably connected to the outer surface of the roller 12, a fixed roller 2 slidably connected inside the main body 1, a support roller 3 slidably connected inside the main body 1, the support roller 3 includes a fixed block 31, a support block 34 fixedly connected below the fixed block 31, a sliding shaft 35 rotatably connected to the inner surface of the fixed block 31, a roller 36 rotatably connected to the outer surface of the sliding shaft 35, a giant roller 32 rotatably connected to the inner surface of the fixed block 31, a gasket 33 threadedly connected to the outer side of the giant roller 32, a working roller 4 slidably connected above the support roller 3, the working roller 4 includes a shaped block 41, a small roller 42 rotatably connected inside the shaped block 41, a fixed piece 43 threadedly connected to the side of the small roller 42, and a positioning block 5 slidably connected to the outer surface of the shaped block 41.

[0019] In this embodiment, through the cooperation of the upper and lower irregular blocks 41 and the positioning block 5, the upper groove of the lower irregular block 41 matches the protrusion below the positioning block 5. After the positioning block 5 is placed, when the irregular block 41 is placed on top of the positioning block 5, the groove at the bottom of the upper irregular block 41 will fall along the protrusion of the positioning block 5 with an inclination. This can ensure that the positions of the upper and lower working rollers 4 are aligned, reduce calibration time, and achieve the purpose of quickly replacing the working rollers 4.

[0020] Example 2 like Figures 1-4As shown, a connector 6 is fixedly connected to the side of the working roller 4. The connector 6 includes a protrusion 61. A spring 63 is sleeved and connected to the side of the protrusion 61. A retainer 62 is slidably connected to the outside of the protrusion 61. An iron ball 64 is slidably connected to the inside of the protrusion 61. An open iron ring 65 is sleeved on the outer surface of the protrusion 61. A tube head 66 is slidably connected to the inner surface of the protrusion 61. A slot adapted to the iron ball 64 is opened inside the protrusion 61. A groove adapted to the iron ball 64 is provided on the outer surface of the tube head 66. A protrusion adapted to the surface of the tube head 66 is provided inside the protrusion 61. A groove adapted to the surface of the positioning block 5 is provided on the surface of the shaped block 41. A protrusion adapted to the outer surface of the sliding bracket 11 is provided on the side of the shaped block 41. A rivet 7 is threadedly connected inside the main body 1.

[0021] In this embodiment, the spring 63 is constrained between the retainer 62 and the protrusion 61 through their cooperation. One end of the protrusion 61 cooperates with the open iron ring 65 to limit the retainer 62 and prevent it from falling off. The retainer 62 also limits the iron ball 64. Pushing the retainer 62 releases the limitation of the iron ball 64, allowing the tube head 66 to push the iron ball 64 outward, so that the tube head 66 can slide out smoothly from inside the protrusion 61, canceling the push on the retainer 62. The spring 63 returns to its original state, causing the retainer 62 to return to its original state, thus achieving the purpose of quickly replacing the pipeline.

[0022] Working principle: like Figures 1-4 As shown, when the stress relief device needs maintenance or replacement, the old working roller 4 is removed, the new working roller 4 is placed above the support roller 3, the positioning block 5 is placed in the groove above the working roller 4, the working roller 4 is placed again, the groove at the bottom of the working roller 4 will fall towards the positioning block 5, pushing the support roller 3, and through the rolling of the roller 36, the support roller 3 is driven to slide into the interior of the main body 1, then the clamp 62 is pushed and inserted into the tube head 66, the force on the clamp 62 is released, the clamp 62 returns to its initial state, the iron ball 64 falls into the groove of the tube head 66, and the tube head 66 is locked, thus completing the pipeline replacement.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
