Description

Technical Field

[0001] The invention relates to the technical field of fire door manufacturing, and in particular to a steel fire door manufacturing device. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Fire doors are fireproof partitions with a certain degree of fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc., used to isolate fire sources and smoke in the event of a fire, to ensure the safe evacuation of personnel.

[0003] For example, in the Chinese patent with announcement number CN220128647U, which is named as a steel fire door assembly positioning tool, the first motor drives the bidirectional threaded rod to rotate by pressing the control panel, and the two sleeve shafts are displaced left and right on the outside of the bidirectional threaded rod. Under the linkage of the two connecting rods, the two inner clamping plates are displaced away from each other and close to the two outer clamping plates, so as to further clamp the fire door body. The second motor drives the threaded column to rotate, so that the slider is displaced up and down inside the fixed column, so as to realize the height adjustment of the two clamped fire door bodies, so that the fire door body is stably clamped and suspended in the air, which is convenient for installation. The fire door body can be rotated by rotating the shaft, and the knob can limit it, so as to facilitate the assembly of the fire door body at different angles.

[0004] For the above related technologies, refer to Figure 3 When assembling the existing fireproof door, it is necessary to first fill the rock wool board 32 inside the door frame shell 3, and then abut the first limiting surface 331 against the second limiting surface 341, so that the left side of the door frame shell 3 and the left side of the door panel 31 are aligned for positioning, and then the right side of the door panel 31 is freely dropped and snapped with the door frame shell 3. The operator can use the above-mentioned assembly positioning tool to adjust the height of the door frame shell 3 and the door panel 31, but the right side of the door panel 31 falls and collides with the door frame shell 3, and the door panel 31 vibrates and produces horizontal displacement, which causes an error in the position between the door frame shell 3 and the door panel 31, and then the door frame shell 3 interferes with the right end of the door panel 31, so that the door panel 31 and the door frame shell 3 may not be snapped.

DETAILED DESCRIPTION

[0017] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 9 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0018] This embodiment provides a steel fire door manufacturing equipment, referring to Figure 1 , Figure 2 and Figure 3 A steel fire door manufacturing device includes a bracket 1, a sliding member 2, a rotating pin 21, a supporting plate 22, a first linear driver 23, a guide slide 25, a second linear driver 24, a first loading plate 26 and a rotating rod 27. The fire door is composed of a door frame shell 3, a rock wool board 32 and a door panel 31. During the processing of the fire door, the rock wool board 32 with flameproof properties is embedded between the door frame shell 3 and the door panel 31, so as to achieve the fire resistance of the fire door. The outer side of the door frame shell 3 is fixedly connected with a first limiting plate 33, and the outer side of the door panel 31 is fixedly connected with a second limiting plate 34. The first limiting plate 33 and the second limiting plate 34 are both bent. The outer side of the first limiting plate 33 is a first limiting surface 331, and the inner side of the second limiting plate 34 is a second limiting surface 341. The first limiting surface 331 abuts against the second limiting surface 341 to position the door frame shell 3 and the door panel 31.

[0019] Reference Figure 1 , Figure 2 and Figure 4The bracket 1 is erected on a horizontal plane, the sliding member 2 is vertically slidably connected to the bracket 1, and the first linear actuator 23 is fixedly connected to the bracket 1, and is used to drive the sliding member 2 to move in the vertical direction. The support plate 22 is hinged to the upper surface of the sliding member 2 through the rotating pin 21, and the support plate 22 is used to place the door frame housing 3. The second linear actuator 24 is fixedly connected to one end of the bracket 1, and the guide slide 25 is hinged to the driving shaft of the second linear actuator 24, and the guide slide 25 is arranged on one side of the rotating pin 21.

[0020] Reference Figure 1 , Figure 2 and Figure 4 The first loading plate 26 is horizontally slidably connected to the bracket 1. The first loading plate 26 is arranged above the support plate 22, and the first loading plate 26 is arranged on the side of the rotating pin 21 away from the guide slide 25. The first loading plate 26 is used to transport the door plate 31 to the support plate 22. A rotating rod 27 is hinged between the first loading plate 26 and the support plate 22. The driving shaft of the first linear actuator 23 is extended through the guide slide 25 to drive the support plate 22 to rotate clockwise around the rotating pin 21 (refer to Figure 2 ), the support plate 22, the rotating rod 27 and the first loading plate 26 form a crank slider mechanism, and the support plate 22 rotates through the rotating rod 27 to drive the first loading plate 26 to reciprocate in the horizontal direction.

[0021] First, place the door frame shell 3 on the support plate 22, and place the door panel 31 on the first loading plate 26. After the processing personnel embed the rock wool board 32 into the door frame shell 3, the driving shaft of the second linear actuator 24 drives the support plate 22 to rotate clockwise around the rotating pin 21 (refer to Figure 2 ), the door frame housing 3 rotates synchronously with the support plate 22, so that the first limit plate 33 rotates upward around the rotation axis. The support plate 22 drives the first loading plate 26 to move close to the support plate 22 through the rotating rod 27, and the door plate 31 moves synchronously with the first loading plate 26, so that the second limit plate 34 moves close to the first limit plate 33, until the second limit plate 34 moves to the side of the first limit plate 33 away from the rotating pin 21.

[0022] The driving shaft of the second linear actuator 24 drives the support plate 22 to rotate counterclockwise around the rotating pin 21 (refer to Figure 2 ), and at the same time, the first linear actuator 23 pushes the support plate 22 to move upward, and the door frame housing 3 rotates and moves synchronously with the support plate 22, so that the first limiting surface 331 abuts against the second limiting surface 341, and the first limiting surface 331 and the door frame housing 3 rotate and move synchronously, and the first limiting surface 331 pulls the door panel 31 out of the first loading plate 26 through the second limiting surface 341. At the same time, the support plate 22 drives the first loading plate 26 to move away from the support plate 22 through the rotating rod 27, so that the door panel 31 is separated from the first loading plate 26 and is transported to the door frame housing 3.

[0023] The support plate 22 and the first loading plate 26 cooperate to complete the conveyance of the door panel 31 to the door frame housing 3, so that the first limiting surface 331 abuts against the second limiting surface 341, thereby completing the positioning of the door frame housing 3 and the door panel 31. In addition, while the first limiting surface 331 pulls the door panel 31 out of the first loading plate 26 through the second limiting surface 341, the first linear actuator 23 pushes the door frame housing 3 upward through the support plate 22, thereby reducing the height difference between the door frame housing 3 and the door panel 31, thereby reducing the height of the door panel 31 falling to the door frame housing 3, thereby reducing the error caused by the collision of the door panel 31 falling and the door frame housing 3, and improving the assembly accuracy of the door frame housing 3 and the door panel 31.

[0024] Reference Figure 5 The first loading plate 26 is horizontally slidably connected to an adjusting plate 261, and the adjusting plate 261 is used to support the door panel 31. The bottom surface of the first loading plate 26 is fixedly connected to a third linear actuator 262 for driving the adjusting plate 261 to move. When the first limiting surface 331 pulls the door panel 31 out of the first loading plate 26 through the second limiting surface 341, the support plate 22 moves upward under the action of the first linear actuator 23, and the third linear actuator 262 pushes the adjusting plate 261 to move close to the support plate 22. The adjusting plate 261 continues to support the door panel 31, slowing down the door panel 31 from separating from the first loading plate 26, and further reducing the height of the door panel 31 falling to the door frame shell 3, thereby improving the assembly accuracy of the door frame shell 3 and the door panel 31.

The positioning mechanism 4 includes a first support block 41, a clamping block 411, an adjusting rod 42, a fastening screw 43 and a positioning plate 44. The first support block 41 is provided with a plurality of and is respectively fixedly connected to the upper surfaces of the support plate 22 and the first loading plate 26, and every two clamping blocks 411 are fixedly connected to the upper surface of one first support block 41, and a slide groove 45 is provided between the two clamping blocks 411, and the adjusting rod 42 is slidably arranged in the slide groove 45, and the positioning plate 44 is fixedly connected to the adjusting rod 42, and the door frame shell 3 and the door panel 31 can both abut against the positioning plate 44, and the processing personnel adjust the distance between the positioning plate 44 and the door frame shell 3 and the door panel 31 by moving the adjusting rod 42. The fastening screw 43 is threadedly connected to the two clamping blocks 411. Rotating the fastening screw 43 can reduce the distance between the two clamping blocks 411, thereby reducing the width of the slide groove 45, so that the adjustment rod 42 can be locked, and the positioning plate 44 can position the door frame shell 3 and the door panel 31.
