Description

Technical Field

[0001] This invention relates to the processing of fire doors, and in particular to a flipping device for fire door production, belonging to the field of fire door production and processing technology. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire compartments, evacuation stairwells and vertical shafts.

[0003] Currently, when manufacturing fire doors, after processing one side, the process of processing the other side usually involves manually flipping the fire door. This method is time-consuming, labor-intensive, and unsafe, and can easily cause injury to workers. Therefore, a flipping device for fire door manufacturing is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The main purpose of this invention is to solve the problem that when processing one side of a fire door after processing the other side, it is usually done manually to flip the fire door, which is time-consuming, labor-intensive, unsafe, and can easily cause injury to workers. The invention provides a flipping device for fire door production.

[0005] The objective of this invention can be achieved by adopting the following technical solution:

[0006] A flipping device for fire door production includes a processing table and two lifting mechanisms located in front of and behind the processing table. Each of the two lifting mechanisms includes a first hydraulic rod fixedly installed on the lower surface of the processing table. The output end of the first hydraulic rod is fixedly connected to a lifting frame. The surface of the lifting frame is fixedly connected to a mounting plate. The surface of the mounting plate is fixedly connected to a second hydraulic rod. The output ends of the two second hydraulic rods are respectively fixedly connected to a cooperating mechanism and a rotating mechanism.

[0007] Furthermore, the cooperating mechanism includes a first push rod fixedly installed at the output end of a second hydraulic rod, the inner wall of the first push rod being provided with a torsion spring, and the inner wall of the first push rod being rotatably connected to a first connecting rod.

[0008] Furthermore, the rotating mechanism includes a rotating rod fixedly installed at the output end of another second hydraulic rod, and a servo motor is fixedly connected to the inner wall of the rotating rod.

[0009] Furthermore, a second connecting rod is fixedly connected to the output end of the servo motor, and a connecting sleeve is fixedly connected to the inner wall of the second connecting rod. The surface of the connecting sleeve is rotatably connected to the rotating rod.

[0010] Furthermore, a clamping mechanism is fixedly connected to one end of both the first connecting rod and the second connecting rod. The clamping mechanism includes a movable plate and a clamping plate that are fixedly connected to the first connecting rod and the second connecting rod, respectively.

[0011] Furthermore, a base plate is fixedly connected to the bottom of the movable plate, and symmetrically distributed guide rods are fixedly connected to the upper surface of the base plate.

[0012] Furthermore, a sliding sleeve is embedded on the surface of the clamping plate, the inner wall of the sliding sleeve is slidably connected to the guide rod, and a baffle is fixedly connected to one end of the guide rod.

[0013] Furthermore, an electric push rod is fixedly connected to the upper surface of the clamping plate, and the output end of the electric push rod passes through the clamping plate and is fixedly connected to the base plate.

[0014] Furthermore, the upper surface of the processing table is inlaid with two fixing plates, the surface of the fixing plates is inlaid with support tubes, and the upper surface of the support tubes is fixedly connected with sealing rings.

[0015] Furthermore, a piston is slidably connected to the inner wall of the support tube, a connecting frame is fixedly connected to the lower surface of the piston, a fixing frame is fixedly connected to the surface of the connecting frame, a third hydraulic rod is fixedly connected to the upper surface of the fixing frame, the lower surface of the processing table is fixedly connected to the third hydraulic rod, and a support leg is fixedly connected to the lower surface of the processing table.

[0016] The beneficial technical effects of this invention are as follows: The third hydraulic rod extends, thereby driving the fixing frame to move downward, which in turn drives the connecting frame to move downward. The connecting frame pulls the piston to slide against the support tube, creating a negative pressure inside the support tube, thereby fixing the fire door. The fire door is less likely to move during processing. The fire door is placed on the upper surface of the processing table and supported by the support tube, so that the bottom of the fire door is suspended. First, the first hydraulic rod retracts, thereby driving the bottom plate to move downward. The second hydraulic rod extends to insert the bottom plate under the fire door. Then, the electric push rod retracts, thereby driving the clamping plate to move downward. The clamping plate and the bottom plate cooperate to clamp the fire door. Holding the fire door, the first hydraulic rod extends, raising the fire door. Then, the servo motor drives the second connecting rod to rotate, causing the fire door to flip. This causes the torsion spring to deform elastically, generating elastic force. Then, the first hydraulic rod retracts, placing the fire door on the support tube. The third hydraulic rod extends, driving the fixing frame to move downwards, which in turn moves the connecting frame downwards. The connecting frame pulls the piston to slide against the support tube, creating a negative pressure inside the support tube. The sealing ring improves the sealing at the connection between the fire door and the support tube, thus fixing the fire door and automatically flipping it, facilitating fire door processing.

[0026] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0027] like Figures 1-6As shown, the fire door production tilting device provided in this embodiment includes a processing table 1 and two lifting mechanisms 2 arranged in front of and behind the processing table 1. Each of the two lifting mechanisms 2 includes a first hydraulic rod 201 fixedly installed on the lower surface of the processing table 1. The first hydraulic rod 201 extends or retracts, thereby driving the lifting frame 202 to move up and down, thereby driving the second hydraulic rod 204 to move up and down. The output end of the first hydraulic rod 201 is fixedly connected to the lifting frame 202. The lifting frame 202 drives the mounting plate 203 to move up and down. The surface of the lifting frame 202 is fixedly connected to the mounting plate 203. The surface of the mounting plate 203 is fixedly connected to the second hydraulic rod 204. The mounting plate 203 fixes the second hydraulic rod 204. When the mounting plate 203 lifts and lowers, it drives the second hydraulic rod 204 to move up and down. The output ends of the two second hydraulic rods 204 are respectively fixedly connected to a cooperating mechanism 3 and a rotating mechanism 4.

[0028] In this embodiment, as Figure 1 As shown, the cooperating mechanism 3 includes a first push rod 301 fixedly installed at the output end of a second hydraulic rod 204. A torsion spring 303 is provided on the inner wall of the first push rod 301. A first connecting rod 302 is rotatably connected to the inner wall of the first push rod 301. The first connecting rod 302 is connected to the torsion spring 303. When the first connecting rod 302 rotates, the torsion spring 303 undergoes elastic deformation, generating elastic force.

[0029] In this embodiment, as Figure 1 As shown, the rotating mechanism 4 includes a rotating rod 401 fixedly installed at the output end of another second hydraulic rod 204. A servo motor 403 is fixedly connected to the inner wall of the rotating rod 401. A second connecting rod 402 is fixedly connected to the output end of the servo motor 403. A connecting sleeve 404 is fixedly connected to the inner wall of the second connecting rod 402. The connecting sleeve 404 rotatably connects the rotating rod 401 and the second connecting rod 402 together. The surface of the connecting sleeve 404 is rotatably connected to the rotating rod 401. The servo motor 403 drives the second connecting rod 402 to rotate, thereby driving the clamping mechanism 5 to rotate.

[0030] In this embodiment, as Figure 1As shown, a clamping mechanism 5 is fixedly connected to one end of the first connecting rod 302 and the second connecting rod 402. The clamping mechanism 5 includes a movable plate 501 and a clamping plate 505, which are fixedly connected to the first connecting rod 302 and the second connecting rod 402, respectively. A base plate 502 is fixedly connected to the bottom of the movable plate 501. A guide rod 503 is fixedly connected to the upper surface of the base plate 502. A sliding sleeve 506 is embedded in the surface of the clamping plate 505. The inner wall of the sliding sleeve 506 is slidably connected to the guide rod 503. A baffle 504 is fixedly connected to one end of the guide rod 503. An electric push rod 507 is fixedly connected to the upper surface of the clamping plate 505. The output end of the electric push rod 507 passes through the clamping plate 505 and is fixedly connected to the base plate 502. The electric push rod 507 extends or retracts, thereby driving the clamping plate 505 to move up and down. The sliding sleeve 506 and the guide rod 503 slide and cooperate, thereby restricting the movement direction of the clamping plate 505.

[0031] Two fixing plates 6 are embedded on the upper surface of the processing table 1. Support tubes 7 are embedded on the surface of the fixing plates 6. A sealing ring 8 is fixedly connected to the upper surface of the support tube 7. A piston 10 is slidably connected to the inner wall of the support tube 7. A connecting frame 9 is fixedly connected to the lower surface of the piston 10. A fixing frame 11 is fixedly connected to the surface of the connecting frame 9. A third hydraulic rod 12 is fixedly connected to the upper surface of the fixing frame 11. The lower surface of the processing table 1 is fixedly connected to the third hydraulic rod 12. A support leg 13 is fixedly connected to the lower surface of the processing table 1. When the fire door is placed on the processing table 1 for processing, the lower surface of the fire door is in close contact with the sealing ring 8. The third hydraulic rod 12 extends, thereby driving the fixing frame 11 to move downward, which in turn drives the connecting frame 9 to move downward. The connecting frame 9 pulls the piston 10 to slide against the support tube 7, creating a negative pressure inside the support tube 7, thereby fixing the fire door.

[0032] The working principle of this invention is as follows: When flipping the fire door, the fire door is placed on the upper surface of the processing table 1 and supported by the support tube 7, so that the bottom of the fire door is suspended. First, the first hydraulic rod 201 is retracted, thereby driving the bottom plate 502 to move down. The second hydraulic rod 204 extends to insert the bottom plate 502 under the fire door. Then, the electric push rod 507 retracts, thereby driving the clamping plate 505 to move down. The clamping plate 505 and the bottom plate 502 cooperate to clamp the fire door. Then, the first hydraulic rod 201 extends, thereby raising the fire door. Then, the servo motor 403 drives the second connecting rod 402 to rotate, thereby driving the fire door to move up and down. The fire door flips, causing the torsion spring 303 to undergo elastic deformation and generate elastic force. Then, the first hydraulic rod 201 retracts, placing the fire door on the support tube 7. The third hydraulic rod 12 extends, thereby driving the fixing frame 11 to move downward, which in turn drives the connecting frame 9 to move downward. The connecting frame 9 pulls the piston 10 to slide against the support tube 7, creating a negative pressure inside the support tube 7. The sealing ring 8 improves the sealing at the connection between the fire door and the support tube 7, thereby fixing the fire door. Then, the electric push rod 507 is reset, and the second hydraulic rod 204 is reset. Under the action of the elastic force, the torsion spring 303 causes the first connecting rod 302 to reset.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
