Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fire door production equipment, specifically relating to a positioning and pressing device for producing fire doors. Background Technology
[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation for a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire-resistant compartments, evacuation stairwells, vertical shafts, and other fire-resistant structures. In addition to the functions of ordinary doors, fire doors also play a crucial role in preventing the spread of fire and smoke, thus ensuring the safe evacuation of personnel for a certain period of time. During the production process of fire doors, lock holes or mounting holes are generally required to be drilled. Therefore, the sheet metal needs to be pressed tightly during the drilling process.
[0003] However, in the current traditional fire door production positioning and clamping devices, most fire doors are usually clamped by workers directly turning the bolts by hand to press and fix them. However, if the force is not applied properly, it can easily lead to hand sprains and uneven stress on the panels, which may increase the risk of safety hazards and panel detachment, and may reduce the efficiency of production and processing.

An installation rod is rotatably installed inside the support plate, and a clamping plate is fixed to the outer wall of the installation rod. Two guide plates are fixed to the top of the processing table, and an adjusting block is slidably installed on the top of the guide plate. Guide holes are respectively opened on both sides of the inner wall of the adjusting block, and a connecting rod is slidably installed inside the guide hole. The connecting rod is rotatably connected to the inside of the clamping plate. A clamping drive mechanism is provided at the bottom of the processing table.
[0006] Preferably, the clamping drive mechanism includes a mounting frame, which is fixed to the bottom of the processing table. A first bidirectional lead screw is rotatably mounted inside the mounting frame. Two sliding blocks are rotatably mounted on the outer wall of the first bidirectional lead screw. A drive motor is fixed to one side of the mounting frame. An adjusting rod is fixed to the bottom of the sliding block. One end of the adjusting rod is fixedly connected to one side of the adjusting block.

[0009] Preferably, the inner wall of the positioning plate and the bottom of the pressing plate are respectively fixed with stabilizing pads, and the stabilizing pads are made of rubber.
[0010] Preferably, an indicator light is fixed on the top of the processing table.
[0011] Compared with the prior art, the beneficial effects of this utility model are: The clamping mechanism and clamping drive mechanism can automatically position and clamp the fire door panels, eliminating the need for workers to spend time and effort manually turning the bolts to fix them. This reduces labor intensity, improves efficiency, and ensures that each clamping point is evenly stressed during clamping, avoiding uneven stress that can occur with manual rotation.

[0016] Please see Figures 1-4 As shown, a positioning and clamping device for producing fire doors includes: a processing table 1, and a clamping mechanism is provided on the top of the processing table 1. The clamping mechanism includes multiple support plates 2, which are fixed to the top of the processing table 1. An installation rod 21 is rotatably installed inside the support plate 2, and a clamping plate 22 is fixed to the outer wall of the installation rod 21. Two guide plates 23 are fixed to the top of the processing table 1. An adjusting block 24 is slidably installed on the top of the guide plate 23. Guide holes 25 are opened on both sides of the inner wall of the adjusting block 24. A connecting rod 26 is slidably installed inside the guide hole 25. The connecting rod 26 is rotatably connected to the inside of the clamping plate 22. A clamping drive mechanism is provided at the bottom of the processing table 1. The clamping drive mechanism includes a mounting frame 3, which is fixed to the bottom of the processing table 1. A first bidirectional lead screw 31 is rotatably mounted inside the mounting frame 3. Two sliding blocks 32 are rotatably mounted on the outer wall of the first bidirectional lead screw 31. A drive motor 33 is fixed to one side of the mounting frame 3. An adjusting rod 34 is fixed to the bottom of the sliding block 32. One end of the adjusting rod 34 is fixedly connected to one side of the adjusting block 24. Protective covers are provided on the outer walls of both the first bidirectional lead screw 31 and the second bidirectional lead screw 42. These are existing technologies and will not be described in detail here.
[0017] As can be seen from the above, in use, the fire door panel is first placed in the designated position on the processing table 1. Then, the drive motor 33 is turned on by the external control device. The output end of the drive motor 33 rotates, driving the first bidirectional lead screw 31 to rotate, which in turn drives the sliding block 32 to move the adjusting rod 34 left and right. This causes the adjusting block 24 to move left and right along the guide plate 23. The movement of the adjusting block 24 causes the connecting rod 26 to slide in the guide hole 25, which in turn causes the pressing plate 22 to rotate, thereby pressing and fixing the fire door panel. Therefore, the pressing mechanism and the pressing drive mechanism can automatically position and press the fire door panel, eliminating the need for workers to spend time and effort manually turning the bolts to fix it. This reduces labor intensity and improves efficiency. At the same time, it can ensure that each pressing point is evenly stressed during pressing and fixing, avoiding uneven stress caused by manual rotation. This helps to improve the firmness of pressing, reduce the risk of falling off, and thus improve the efficiency of production and processing. Example
[0018] refer to Figures 1-4 As shown, two positioning plates 4 are provided on the top of the processing table 1. A servo motor 41 is fixed on one side of the processing table 1. A second bidirectional lead screw 42 is fixed to the output end of the servo motor 41. Two moving blocks 43 are threadedly connected to the outer wall of the second bidirectional lead screw 42. The top of the moving blocks 43 is fixedly connected to the bottom of the positioning plate 4. Two limit rods 5 are fixed on one side of one positioning plate 4, and two limit grooves 6 are opened on one side of the other positioning plate 4. Stabilizing pads 7 are fixed to the inner wall of the positioning plate 4 and the bottom of the pressing plate 22, respectively. The material of the stabilizing pads 7 is rubber. An indicator light 8 is fixed on the top of the processing table 1.
[0019] As can be seen from the above, the servo motor 41 is activated by an external control device. The output of the servo motor 41 rotates, driving the second bidirectional lead screw 42 to rotate. This, in turn, drives the moving block 43 to move the positioning plates 4 away from or towards each other. This allows the fire door material to be clamped and positioned during processing, and then pressed tightly, thus ensuring the stability of the fire door material and preventing shaking or displacement, thereby improving processing accuracy. The sliding of the limit rod 5 in the limit groove 6 allows the positioning plates 4 to remain stable when moving away from or towards each other, preventing displacement between the two positioning plates 4, thus further ensuring the stability of the fire door material. The stabilizing pad 7 increases friction, improving the stability during fixing, and also protects the outer surface of the fire door material, reducing wear. The indicator light 8 flashes during processing, thus alerting nearby personnel that processing is in progress and preventing accidental entry and potential safety accidents.
