Description

Technical Field

[0001] This utility model relates to the field of frame bending technology, specifically a bending device for producing high-sealing smoke exhaust fire damper frames. Background Technology

[0002] Smoke exhaust fire dampers are core components of building fire protection systems. They can automatically block smoke ducts during a fire. Their frames are mostly made of stainless steel or galvanized steel plates. During production, they need to be formed through a precision bending process to ensure the structural strength and sealing performance at the corners. The bending process requires precise control of angle tolerances to avoid material deformation affecting the valve's sealing performance.

[0003] A search revealed a Chinese patent with publication number CN221983587U that discloses a bending device for producing fire damper frames. The device includes a bending platform with a first rectangular hole at the middle of the upper surface of the bending platform. The first rectangular hole has first rectangular grooves on both the left and right sides inside. Sliding devices are provided on the two first rectangular grooves, and clamping devices are provided on the sliding devices.

[0004] While the above-mentioned solution can perform bending operations, there is still room for optimization in practical applications. Because the current equipment requires multiple repetitions to complete the material forming, it not only has low production efficiency but also makes it difficult to bend the material into different shapes according to production needs, resulting in low production adaptability. To address these issues, we provide a high-sealing smoke exhaust fire damper frame production bending device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, this utility model provides a technical solution for a bending device for producing a high-sealing smoke exhaust fire damper frame, including a workbench 1. The workbench 1 is electrically connected to the municipal power supply via a wire, thereby ensuring the normal power supply of the electrical equipment in this application.

[0024] like Figure 2 and Figure 3 As shown, the workbench 1 is equipped with a bending mechanism 2. The bending mechanism 2 includes an adjustment box 201. The bottom surface of the adjustment box 201 is fixedly connected to the workbench 1. The outer surface of the adjustment box 201 is fixedly connected to a first auxiliary plate 202. By setting the first auxiliary plate 202, the material can be effectively bent into an angled shape when the bending roller 212 pushes the material.

[0025] A driven gear ring 203 is rotatably connected to the inner wall of the regulating box 201. A gear 204 is meshed with the outer surface of the driven gear ring 203. The two ends of the gear 204 are rotatably connected to the regulating box 201. A sliding gear plate 205 is meshed with the outer surface of the gear 204. The outer surface of the sliding gear plate 205 is slidably connected to the regulating box 201. By rotating the driven gear ring 203, the six gears 204 can be driven to rotate simultaneously.

[0026] One end of the sliding toothed plate 205 is fixedly connected to a second auxiliary plate 206, and the top of the adjusting box 201 is rotatably connected to a drive shaft 207. By driving the six second auxiliary plates 206 to spread outward synchronously until they cover the first auxiliary plate 202, the material can be bent in an arc shape.

[0027] One end of the drive shaft 207 is fixedly connected to the driven box 208. The top surface of the driven box 208 is slidably connected to the worktable 1. By driving the drive shaft 207 to rotate, the driven box 208 can be driven to rotate synchronously around the drive shaft 207.

[0028] An electric actuator 209 is fixedly connected to the inner wall of the driven box 208. An adjusting slider 210 is fixedly connected to the telescopic end of the electric actuator 209. The outer surface of the adjusting slider 210 is slidably connected to the driven box 208. A connecting rod 211 is fixedly connected to the bottom surface of the adjusting slider 210. A bending roller 212 is rotatably connected to the end of the connecting rod 211 away from the adjusting slider 210. By driving the driven box 208 to rotate, the bending roller 212 can be driven to rotate synchronously, effectively extruding and bending the material.

[0029] A drive motor 213 is fixedly connected to the inner wall of the regulating box 201. The output end of the drive motor 213 is fixedly connected to the drive shaft 207. The control button of the drive motor 213 is integrated on the outer surface of the worktable 1. The drive motor 213 can be started and stopped by the control button.

[0030] like Figure 1 and Figure 4 As shown, a support mechanism 3 is provided on the outside of the workbench 1. The support mechanism 3 includes an electric actuator 301. The fixed end of the electric actuator 301 is fixedly connected to the workbench 1. The telescopic end of the electric actuator 301 is fixedly connected to a connecting slider 302. The outer surface of the connecting slider 302 is slidably connected to the workbench 1. By activating the electric actuator 301, it extends and retracts, causing the support plate 303 to move closer to the material, thereby effectively supporting the material.

[0031] A support plate 303 is fixedly connected to the top surface of the connecting slider 302, and two guide wheels 304 are rotatably connected to the inner wall of the worktable 1. The guide wheels 304 make it more stable when the material is conveyed from the outside to the surface of the worktable 1.

[0032] The electric actuator 209, drive motor 213, and electric actuator 301 mentioned in this application are all common electrical devices in the prior art. This application will not elaborate on their models and internal structures, and they can also be replaced by other power sources.

[0033] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0034] Working Principle: First, the material is conveyed to the workbench 1 by an external conveying device. Then, the electric actuator 209 is activated to extend and retract, causing the adjusting slider 210 to slide in the driven box 208. The sliding of the driven box 208 causes the bending roller 212 at one end of the connecting rod 211 to move closer to one end of the first auxiliary plate 202, thereby making the material close to the first auxiliary plate 202 and the bending roller 212. At this time, the drive motor 213 is activated to drive the drive shaft 207 to rotate. The rotation of the drive shaft 207 causes the driven box 208 to rotate around the drive shaft 207. The rotation of the driven box 208 causes the bending roller 212 to rotate. During the rotation of the bending roller 212, in conjunction with the synergistic effect of the first auxiliary plate 202, the material is effectively bent into an angled shape. Thus, through the connection and cooperation of the bending roller 212, the first auxiliary plate 202, and the external conveying device, the material is effectively bent into a rectangle. When the material is produced... When production demands bending materials into arcs of different diameters, the rotating motor inside the regulating box 201 drives a gear 204 to rotate. The rotation of gear 204 drives the driven gear ring 203 to rotate synchronously. The rotation of the driven gear ring 203, in turn, drives six gears 204 to rotate synchronously through meshing force. The rotation of the six gears 204 drives the second auxiliary plates 206 at one end of the six sliding tooth plates 205 to move outward synchronously until the six second auxiliary plates 206 spread outward and cover the first auxiliary plate 202. Then, when the bending roller 212 is driven to rotate around the drive shaft 207, the material can be bent into an arc shape. This significantly improves the multifunctionality and production adaptability of the device. Furthermore, through the synergistic effect of the two guide wheels 304 and the support plate 303, the material can be effectively supported during the bending process, greatly improving the quality of the frame production process.
