Description

Trimming device for fire door frames Technical Field

[0001] This utility model belongs to the technical field of repair devices, and particularly relates to a trimming device for fireproof door frames. Background Technology

[0002] Existing edge trimming devices for fire door frames are tools or equipment used to precisely process the edges of the door frame during the production or installation of fire doors. Their core function is to ensure that the edges of the door frame are flat and have good sealing performance, thereby meeting the fire resistance requirements of fire doors.

[0003] However, after long-term use, the fire door frame is prone to deformation on one side due to the weight of the fire door, which affects the normal closing of the fire door. During maintenance, it is necessary to maintain the verticality of the adjacent sides of the fire door frame. Therefore, an edge trimming device for fire door frames is provided. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to correct the verticality of adjacent sides of fire door frames and maintain the supporting strength of fire door frames.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a trimming device for fireproof door frames, comprising a base plate with positioning holes at the corners of the base plate, a reference plate, an inner limiting correction mechanism, and an outer limiting correction mechanism. The reference plate is fixedly connected to the center of the base plate, the inner limiting correction mechanism is fixedly connected to the upper wall of one end of the base plate, and the outer limiting correction mechanism is fixedly connected to the upper part of the base plate away from the inner limiting correction mechanism. The inner and outer limiting correction mechanisms are arranged opposite to each other and perpendicular to the reference plate. A support assembly is provided on the bottom wall of the base plate, and an air pump is fixedly connected inside the support assembly for driving the inner and outer limiting correction mechanisms.

[0006] Furthermore, the external limiting correction mechanism includes a vertical plate, a cylinder, and a support plate. The vertical plate is fixedly connected to the upper wall of one end of the base plate, the cylinder is fixedly installed on the side wall of the vertical plate near the reference plate, and the support plate is fixedly connected to the telescopic end of the cylinder.

[0007] Furthermore, the inner limit correction mechanism includes a second upright plate, a second cylinder, and a second support plate. The second upright plate is fixedly connected to the upper wall of the bottom plate away from the first upright plate. The second cylinder is fixedly installed on the side wall of the second upright plate near the reference plate. The second support plate is fixedly connected to the telescopic end of the second cylinder.

[0008] Furthermore, the reference plate is set in a V-shape at 90 degrees, the first support plate matches the shape of the reference plate and is attached to the outer wall of the reference plate, the second support plate is set parallel to the second vertical plate, and the two ends of the second support plate are bent and parallel to the inner wall of the reference plate.

[0009] Furthermore, the support assembly includes a connecting plate and movable wheels. The connecting plate is fixedly connected to the bottom wall of the base plate and is symmetrically distributed. The movable wheels are rotatably connected to the opposite inner walls of the connecting plate and are symmetrically distributed in pairs.

[0010] Furthermore, a lifting plate is fixedly connected to the side wall of the base plate, and a lifting hole is opened in the middle of the lifting plate.

[0011] With the above structure, the beneficial effects of this utility model are as follows: For the correction of the verticality of the adjacent sides of the fire door frame, the lifting plates and support components on both sides of the base plate facilitate the movement of the pulling device, or the long bolts are inserted through the through holes at the corners of the base plate to fix it on the table. One side corner of the fire door frame is attached to the inner or outer wall of the reference plate, and is supported by the inner or outer limit correction mechanism respectively, so that the corner of the fire door frame remains vertical. Each corner is supported in turn to make the adjacent sides of the fire door frame vertical and maintain a regular quadrilateral structure. Attached Figure Description

[0017] As shown in Figure 1-3, the trimming device for fire door frames includes a base plate 1 with positioning holes 2 at its corners. It also includes a reference plate 3, an inner limiting correction mechanism 4, and an outer limiting correction mechanism 5. The reference plate 3 is fixedly connected to the center of the base plate 1. The inner limiting correction mechanism 4 is fixedly connected to the upper wall of one end of the base plate 1. The outer limiting correction mechanism 5 is fixedly connected to the upper part of the end of the base plate 1 away from the inner limiting correction mechanism 4. The inner limiting correction mechanism 4 and the outer limiting correction mechanism 5 are arranged opposite to each other and are aligned with the reference plate 3. The plates 3 are perpendicular to each other, and the bottom wall of the base plate 1 is provided with a support component 6. An air pump 7 is fixedly connected inside the support component 6 for driving the inner limit correction mechanism 4 and the outer limit correction mechanism 5. When one side corner of the fire door frame is attached to the outer wall of the reference plate 3, the outer limit correction mechanism 5 is used to push the outer wall of the fire door frame to make it fit with the reference plate 3. Or when one side corner of the fire door frame is attached to the inner wall of the reference plate 3, the inner limit correction mechanism 4 is used to push the inner wall of the fire door frame to fit with the reference plate 3, thereby achieving the correction of the corner of the fire door frame.

[0018] As shown in Figures 1 and 3, in order to provide a reference for the correction of adjacent sides of the fire door frame, the reference plate 3 is set in a V-shape at 90 degrees. The support plate 10 matches the shape of the reference plate 3 and is attached to the outer wall of the reference plate 3. The support plate 2 12 is set parallel to the vertical plate 2 17, and the two ends of the support plate 2 12 are bent and parallel to the inner wall of the reference plate 3. According to the structural characteristics of the fire door frame, its corners are attached to the 90-degree bent reference plate 3, and through pressure contact, the adjacent sides of the fire door frame are attached to the reference plate 3, thereby realizing the verticality correction of the adjacent sides.

[0019] As shown in Figures 1 and 3, in order to increase the correction accuracy of the fire door frame, force is applied to the inner and outer sides of the fire door frame. The outer limit correction mechanism 5 includes a vertical plate 8, a cylinder 9, and a support plate 10. The vertical plate 8 is fixedly connected to the upper wall of one end of the base plate 1. The cylinder 9 is fixedly installed on the side wall of the vertical plate 8 near the reference plate 3. The support plate 10 is fixedly connected to the telescopic end of the cylinder 9. The cylinder 9 is supported by the vertical plate 8 and pushes the support plate 10 to contact the outer wall of the reference plate 3, pushing and clamping the corners of the fire door frame to realize the reset of the corners of the fire door frame and maintain the verticality of the adjacent sides.

[0020] The inner limit correction mechanism 4 includes a second upright plate 17, a second cylinder 11, and a second support plate 12. The second upright plate 17 is fixedly connected to the upper wall of the bottom plate 1 away from the first upright plate 8. The second cylinder 11 is fixedly installed on the side wall of the second upright plate 17 near the reference plate 3. The second support plate 12 is fixedly connected to the telescopic end of the second cylinder 11. The second upright plate 17 supports the second cylinder 11, drives the second cylinder 11 to extend and pushes the second support plate 12 close to the inner wall of the reference plate 3. The bending points at both ends of the second support plate 12 are used to make the edge of the fire door frame fit with the inner wall of the reference plate 3, thereby realizing the reset of the fire door frame.

[0021] As shown in Figure 2, in order to achieve the mobility and fixation of the device, the support component 6 includes a connecting plate 13 and a moving wheel 14. The connecting plate 13 is fixedly connected to the bottom wall of the base plate 1 and is symmetrically distributed. The moving wheel 14 is rotatably connected to the opposite inner wall of the connecting plate 13 and is symmetrically distributed in pairs. A lifting plate 15 is fixedly connected to the side wall of the base plate 1. A lifting hole 16 is opened in the middle of the lifting plate 15. When moving, one side of the lifting plate 15 can be dragged to make the moving wheel 14 slide on the ground, which facilitates the movement of the device.

[0022] In actual use, the operator will move the device according to the position of the fire door frame. The operator can drag the lifting plate 15 on one side to make the moving wheel 14 slide on the ground, so that the device can be movably assembled and connected with the fire door frame, or the device can be fixed on the table by inserting long bolts through the through hole at the corner of the base plate 1.

[0023] Make the inner wall of the corner of the fire door frame fit against the outer wall of the reference plate 3, drive cylinder 9 to extend, support plate 10 contacts the outer wall of the reference plate 3 through the protective door frame, push and clamp the corner of the fire door frame, realize the reset of the corner of the fire door frame, and maintain the perpendicularity of the adjacent side.

[0024] Alternatively, the outer wall of the fire door frame can be made to fit against the inner wall of the reference plate 3, and the second cylinder 11 can be extended and pushed to bring the second support plate 12 close to the inner wall of the reference plate 3. The bending points at both ends of the second support plate 12 can be used to make the edge of the fire door frame fit against the inner wall of the reference plate 3, thereby realizing the reset of the fire door frame.
