[0002] Civil defense doors (civil air defense engineering protective doors) are special doors used in protective fortifications, basements, and other locations, providing protection against shock waves, toxic gases, and fires. They come in a wide variety of accessories, with slight differences between different types of civil defense doors (such as steel structure protective airtight doors and reinforced concrete protective doors).

[0003] However, existing air defense doors often suffer from bending of steel plates or materials during manufacturing, affecting assembly and use. Therefore, straightening devices are needed to straighten the steel. However, when existing straightening devices straighten the steel, metal particles adhering to the steel surface can cause dents and scratches as the straightening rollers pass over the steel. Surface damage may become stress concentration points, reducing the fatigue strength of the components and even affecting the subsequent assembly accuracy. Therefore, a straightening device for air defense door components that can clean the surface of steel components is proposed. Utility Model Content

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.

[0031] Please see Figures 1-4 This utility model provides a technical solution:

[0032] A straightening device for a civil defense door fitting, comprising:

[0033] A base frame 1, above which a liftable movable frame 3 is installed, and inside the movable frame 3 is a straightening mechanism 5 for straightening steel fittings; and

[0034] A cleaning mechanism 6 is located on one side of the movable frame 3. It is used to clean the metal impurities adhering to the surface of the steel fittings that enter the straightening mechanism 5.

[0035] A straightening mechanism 5 is installed inside the movable frame 3 to straighten the steel fittings. A cleaning mechanism 6 is installed on one side of the movable frame 3. The cleaning mechanism 6 cleans the metal impurities adhering to the surface of the steel fittings that need to be straightened after entering the straightening mechanism 5. This prevents the metal impurities from causing dents and scratches on the surface of the steel after it has been straightened by the straightening mechanism 5. Damage to the surface of the steel fittings may become stress concentration points, reduce the fatigue strength of the fittings, and affect the service life of the fittings.

[0036] Cleanup organization 6 includes:

[0037] The bracket 21 is located on one side of the movable frame 3. A bidirectional screw 23 is rotatably installed inside the bracket 21. One end of the bidirectional screw 23 passes through the side wall of the bracket 21 and is keyed to the output shaft of the servo motor 22.

[0038] The clamping frame 24 is threaded onto the opposite threads on the outer arc surfaces of the two-way screw 23. The upper opposite side walls of the clamping frame 24 are set in an arc shape, and a removable cleaning cloth is provided inside the arc-shaped inner wall for cleaning metal impurities adhering to the outer arc surface of the steel fittings.

[0039] The bracket 21 is mounted on the side wall of the movable frame 3, and is located on the side where the steel enters. A bidirectional screw 23 is rotatably mounted inside the bracket 21. One end of the bidirectional screw 23 passes through the side wall of the bracket 21 and is keyed to the output shaft of the servo motor 22. The models of the servo motor 22 and the controller 8 can be purchased online according to actual usage requirements and are not within the scope of protection of this application. When straightening the steel parts is required, the controller 8 first controls the servo motor 22 to start, driving the bidirectional screw 23 to rotate, causing the two sets of clamping frames 24 to move relative to each other. The movement causes the removable cleaning cloths on the opposite sidewalls of the two sets of clamping frames 24 to adhere tightly to the steel surface. The material of the cleaning cloths can be purchased online according to the actual use and is not within the scope of protection of this application. The end of the steel is placed inside the straightening mechanism 5. During the straightening process of the straightening mechanism 5, the cleaning cloths on the opposite sidewalls above the clamping frames 24 clean the metal impurities on the steel surface in advance, so as to avoid the metal impurities adhering to the steel surface and causing damage to the steel surface during the straightening process, thereby affecting the service life of the steel accessories.

[0040] The five directly affiliated institutions include:

[0041] The transmission roller 12 is rotatably disposed at both ends inside the straightening frame 10, and the top end of the transmission roller 12 passes through the top surface of the straightening frame 10 and is keyed to the motor 13.

[0042] Straightening rollers 11 are equidistantly arranged inside the straightening frame 10 and located between two sets of drive rollers 12; and

[0043] A drive assembly used to adjust the distance between two sets of straightening frames 10.

[0044] The driver components include:

[0045] The hydraulic telescopic rod 9 is installed on the inner walls of both sides of the movable frame 3, and the output end of the hydraulic telescopic rod 9 is connected to the side wall of the straightening frame 10.

[0046] A limiting block 15 is symmetrically provided on the bottom surface of the straightening frame 10. It is slidably disposed inside the guide groove 14 opened on the bottom surface of the movable frame 3, and is used to limit the direction of movement of the straightening frame 10.

[0047] Furthermore, hydraulic telescopic rods 9 are symmetrically arranged on the inner wall above the movable frame 3. The working end of the hydraulic telescopic rod 9 is fixedly connected to the straightening frame 10. Both ends of the opposite side walls of the two sets of straightening frames 10 are provided with transmission rollers 12. The top end of the transmission roller 12 passes through the top surface of the straightening frame 10 and is keyed to the output shaft of the motor 13. The transmission roller 12 is driven to rotate by the motor 13 to transmit and feed the steel parts.

[0048] Meanwhile, multiple straightening rollers 11 are equidistantly arranged between the two sets of transmission rollers 12 inside the straightening frame 10. The straightening rollers 11 straighten the steel parts. During the process of the transmission rollers 12 driving the straightening frame 10 forward, the straightening rollers 11 are driven to rotate, thereby reducing the friction between the straightening rollers 11 and the steel parts.

[0049] The models of the hydraulic telescopic rod 9 and the motor 13 can be purchased online according to actual usage needs. They are not within the scope of protection of this application, so they will not be described in detail.

[0050] The inner bottom surface of the movable frame 3 is provided with a placement groove 16. The second jack 17 is installed inside the placement groove 16. Its top end is connected to the lifting plate 18. The top surface of the lifting plate 18 is connected to the fixed frame 19 by a spring. The top end of the fixed frame 19 is rotatably provided with a support roller 20 for supporting the straightened steel accessories.

[0051] Furthermore, a placement groove 16 is provided on the inner bottom surface of the movable frame 3. A second jack 17 is placed inside the placement groove 16. The working end of the second jack 17 extends to drive the lifting plate 18 to rise and fall. This causes the top surface of the lifting plate 18 to rise and fall through the fixed frame 19 connected by springs. The top of the fixed frame 19 is provided with multiple rotating support rollers 20. Due to the elastic force of the springs, the lifting plate 18 is squeezed upwards, causing the outer arc surface of the support rollers 20 to fully fit with the outer arc surface of the steel fittings. This supports the straightened steel through the support rollers 20, preventing the steel from falling from the straightening rollers 11 set between the two sets of straightening frames 10 under the action of gravity.

[0052] The bottom surface of the movable frame 3 is connected to the working end of the first jack 4. The first jack 4 is set on the top surface of the base frame 1.

The side wall of the movable frame 3 is equipped with a controller 8. The bottom surface of the base frame 1 is equipped with casters 2.

[0053] Finally, the movable frame 3 can be raised and lowered under the drive of the first jack 4, so as to adjust the height of the straightening mechanism 5 inside the movable frame 3, so as to adjust the height of the straightening mechanism 5 according to different operating requirements, thereby increasing the applicability of this utility model.

[0054] Working principle: After the worker places the steel on one side of the straightening mechanism 5, the servo motor 22 is started by the controller 8, so that the two sets of clamping frames 24 clamp the steel. The cleaning cloth set on the side wall of the clamping frame 24 is in contact with the outer arc surface of the steel. After the steel is fixed, the working end of the hydraulic telescopic rod 9 is extended by the controller 8, so that the straightening rollers 11 and transmission rollers 12 set on the side wall of the two sets of straightening frames 10 clamp the steel parts. At this time, the motor 13 is started, and the motor 13 drives the transmission roller 12 to rotate, thereby causing the steel to be conveyed forward. When the steel passes through the inside of the straightening roller 11, the straightening roller 11 straightens the steel and extends out from the other end of the movable frame 3.
