Description

Technical Field

[0001] This utility model relates to the field of fire door hot pressing technology, and in particular to a fire door production hot pressing mechanism. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and thermal 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 similar locations. In addition to the functions of ordinary doors, fire doors also prevent the spread of fire and smoke, ensuring the safe evacuation of personnel for a certain period of time.

[0003] The existing hot-pressing process for fire doors generally involves workers placing the fire door on a hot-pressing platform, manually aligning the fire door, and then starting the hot-pressing equipment to press the fire door. Some fire doors require multiple presses. After each press, workers need to manually align the fire door to avoid errors in the pressing position.

[0004] Based on the aforementioned technologies, the applicant believes that fire doors are heavy, and the manual placement of fire doors is inefficient and prone to inaccurate placement, leading to errors in the stamping position. In addition, the temperature of the fire doors is very high during the hot pressing process, which can easily burn workers. In response to the above problems, we have introduced a hot pressing mechanism for fire door production. Utility Model Content

[0022] Reference Figure 1 - Figure 4A fire door manufacturing hot pressing mechanism includes a base 1, with feet 2 symmetrically fixedly connected to both sides of the bottom of the base 1. A stamping groove 3 is formed on the top of the base 1. A power cavity 4 is formed inside the base 1, and a positioning mechanism 5 is provided inside the power cavity 4. The positioning mechanism 5 includes a positioning component and a protective component, which cooperate with each other. The positioning component includes a connecting block 51, which is symmetrically fixedly connected to the top of the inner wall of the power cavity 4. A slide rail 52 is fixedly connected to the bottom of the connecting block 51. Sliding plates 53 are slidably connected to the bottom of the two slide rails 52 on the same side, and a pull plate is rotatably connected to the bottom of each of the two sliding plates 53. 54. A gear 55 is rotatably connected inside the power chamber 4. A rotating plate 56 is rotatably connected to the bottom of the gear 55. The rotating plate 56 and the pulling plate 54 are rotatably connected. A cylinder 57 is fixedly connected to the top of the inner wall of the power chamber 4. A connector 58 is fixedly connected to the telescopic end of the cylinder 57. A rack 59 is fixedly connected to the outside of the connector 58. The rack 59 meshes with the gear 55. Circumvention grooves 511 are symmetrically opened on both sides of the top of the base 1. Push rods 510 are symmetrically fixedly connected to the top of the two sliding plates 53. A positioning plate 512 is symmetrically slidably connected inside the stamping groove 3. The positioning plate 512 and the push rod 510 are fixedly connected. A rotating groove 6 is symmetrically opened at the bottom of the inner wall of the stamping groove 3. Rollers 7 are rotatably connected at equal intervals inside the rotating groove 6.

[0023] In the above technical solution, considering the large weight of fire doors, the inefficiency and inaccuracy of manually placing them, which could lead to errors in the stamping position, and the high temperature of the fire doors during the hot pressing process, which could easily burn workers, the specific operation is as follows:

[0024] Reference Figure 1 - Figure 4 In a preferred embodiment, the output end of the cylinder 57 drives the connector 58 to move, the connector 58 moves the rack 59 to move, the rack 59 moves the gear 55 to rotate, the gear 55 rotates the rotating plate 56 to rotate, the rotating plate 56 rotates and pulls the two pulling plates 54 to move closer to each other, so that the two sliding plates 53 slide at the bottom of the slide rail 52 to move closer to each other, so that the push rod 510 pushes the two positioning plates 512 to move closer to each other, and the two positioning plates 512 push the fire door to the middle until the fire door is clamped and fixed directly below the stamping assembly. Through the positioning mechanism 5, the fire door can be quickly positioned. During the stamping process, the fire door is fixed to avoid displacement that would cause incorrect stamping position. At the same time, no manual placement is required during placement, reducing labor intensity. The structure is simple and highly practical.

[0025] Reference Figure 1 - Figure 4In a preferred embodiment, a positioning strip 8 is fixedly connected to one side of the inner wall of the stamping groove 3. Rubber pads for increasing friction are fixedly connected to the sides of the two positioning plates 512 that are close to each other. The positioning strip 8 provides auxiliary positioning for the fire door, and the rubber pads increase friction, making the fire door more stable. A controller 9 is fixedly connected to one side of the top of the base 1. The controller 9 allows operators to easily control the opening and closing of the cylinder 57, simplifying operation.

[0026] Working principle: In actual use, the staff places the fire door inside the stamping groove 3. The roller 7 reduces the friction between the fire door and the inner wall of the stamping groove 3. After the fire door is placed, the cylinder 57 is activated. The output end of the cylinder 57 drives the connector 58 to move. The movement of the connector 58 drives the rack 59 to move. The movement of the rack 59 drives the gear 55 to rotate. The rotation of the gear 55 drives the rotating plate 56 to rotate. The rotation of the rotating plate 56 pulls the two pulling plates 54 to move closer to each other, so that the two sliding plates 53 slide closer to each other at the bottom of the slide rail 52. Thus, the push rod 510 pushes the two positioning plates 512 to move closer to each other. The two positioning plates 512 push the fire door towards the middle until the fire door is clamped and fixed directly below the stamping assembly, and then hot pressing begins.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
