[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1-5As shown, a flatness correction device for air defense doors includes a correction component 1 that can apply pressure to correct uneven parts of the raw materials for air defense door production. A loading component 2 is provided in front of the correction component 1 to ensure the correction effect of the device on raw materials for air defense doors of different specifications. A displacement component 3 is provided on the loading component 2 to conveniently adjust the position of the raw materials for air defense doors within the device according to the correction needs.

[0031] In this embodiment: the correction component 1 includes a base 101, a processing table 102 is fixedly installed on the top of the base 101, a diagonal brace 103 is fixedly connected to the front of the base 101, a frame 104 is fixedly connected to the rear of the base 101, a hydraulic cylinder 105 is fixedly installed inside the frame 104, and a pressure block 106 is fixedly connected to the telescopic end of the hydraulic cylinder 105.

[0032] The base 101 provides installation positions for components such as the processing table 102, the bracket 201, and the intermediate frame 202. The processing table 102 is used to place the raw materials for the civil defense door production to be calibrated. The diagonal brace 103 improves the stability of the base 101. The height of the pressure block 106 is adjusted by the hydraulic cylinder 105 installed in the frame 104, so that the pressure block 106 can contact the raw materials for the civil defense door production placed on the processing table 102 and transmit the pressure from the hydraulic cylinder 105 to the position of the raw materials for the civil defense door production to be calibrated.

[0033] In this embodiment: the loading component 2 includes a bracket 201 fixedly connected to the front side of the base 101, an intermediate frame 202 is provided between the brackets 201, a support rod 203 is fixedly installed between the brackets 201 and the intermediate frame 202, a slide 204 is movably connected between the support rods 203, and a first hydraulic rod 205 is movably installed between the intermediate frame 202 and the slide 204.

[0034] The intermediate frame 202 and the slide 204 are rotatably connected to the first hydraulic rod 205, and the support rod 203 is slidably connected to the slide 204.

[0035] The support rod 203 is stably installed in front of the base 101 by the bracket 201 and the intermediate frame 202. The support rod 203 restricts the movable range of the slide 204. The lateral position of the slide 204 is adjusted by the first hydraulic rod 205 connected to the intermediate frame 202 at its tail end, so that the slide 204 can drive the displacement component 3 to move laterally.

[0036] In this embodiment: the shifting component 3 includes a lifting member that can raise the raw material for the production of air-raid shelter doors obliquely to a certain height within the device, a moving member that allows the position of the raw material to be easily adjusted, and a clamping member that can provide the same fixing effect for raw materials for the production of air-raid shelter doors of different specifications. The lifting member includes a reversing frame 301 movably connected to the slide 204, and the moving member includes a third hydraulic rod 303 fixedly installed on the reversing frame 301. The telescopic end of the third hydraulic rod 303 is fixedly connected to a slide 304, and a rotating shaft 3 is movably installed on the slide 304. 05. The lifting component also includes a second hydraulic rod 302 movably installed between the slide 204 and the reversing frame 301. The clamping component includes a rotating frame 306 fixedly connected to one end of the rotating shaft 305. A support 307 is fixedly connected to the rotating frame 306. A lead screw 308 is movably connected between the two supports 307 located in front of and behind the rotating shaft 305. A knob 309 is fixedly connected to one end of the lead screw 308. A slider 310 is provided between the rotating frame 306 and the lead screw 308. A locking block 311 is fixedly connected to one side of the slider 310.

[0037] The reversing frame 301 and the second hydraulic rod 302 are rotatably connected to the uniform slide 204. The reversing frame 301 and the second hydraulic rod 302 are rotatably connected. The reversing frame 301 and the slide 304 are slidably connected. The slide 304 and the rotating shaft 305 are rotatably connected. The rotating frame 306 and the slider 310 are slidably connected. The support 307 and the lead screw 308 are rotatably connected. The lead screw 308 and the slider 310 are connected by threads.

[0038] The second hydraulic rod 302, connected to the slide 204 at its tail end, drives the reversing frame 301 to rotate relative to the slide 204. The third hydraulic rod 303 drives the slide block 304 to slide relative to the reversing frame 301. The rotating shaft 305 allows the clamping component, composed of the rotating frame 306 and other components, to rotate relative to the slide block 304 after being suspended in the air. The rotating frame 306 provides an installation position for the support 307 and limits the movable range of the slider 310. The lead screw 308, which can rotate relative to the support 307, drives the slider 310 to slide relative to the rotating frame 306. The lead screw 308 can be easily rotated by the knob 309. The locking block 311, which can move with the slider 310, contacts and locks the edges and corners of the raw materials for the air defense door production.

[0039] Working principle: When this device is installed for the flatness correction of the air defense door, when it is necessary to move the air defense door production material placed on the processing table 102 to change its pressure position, the first hydraulic rod 205 can be activated to make the locking block 311 close to the air defense door production material. Then, the screw 308 is rotated by the knob 309 so that each locking block 311 can contact and lock the edges and corners of the air defense door production material. After that, the air defense door production material can be moved as needed.

[0040] If it is necessary to adjust the horizontal position of the raw material for the production of the air defense door, the first hydraulic rod 205 or the third hydraulic rod 303 can be activated so that the raw material for the production of the air defense door, which is being clamped, can move laterally or longitudinally on the processing table 102 as needed.

[0041] If it is necessary to flip the raw material for the air-raid shelter door, the second hydraulic rod 302 can be activated, causing the reversing frame 301 to rotate relative to the slide 204, thereby driving the slide 304, rotating shaft 305, rotating frame 306 and other components, as well as the raw material for the air-raid shelter door being clamped, to rise obliquely. Thus, without the raw material for the air-raid shelter door touching or colliding with other components of the device, the processing table 102 is raised to a certain height. After the raw material for the air-raid shelter door has risen to an appropriate height, the operator can flip the raw material for the air-raid shelter door and activate the second hydraulic rod 302 again to reset the raw material for the air-raid shelter door. Afterwards, the flipped raw material for the air-raid shelter door can be further corrected.

[0042] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
