Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a clamping device for stitching galvanized steel sheet ducts. Background Technology

[0002] Galvanized steel sheet ducts have been widely used in numerous fields due to their superior performance. In the construction industry, galvanized steel sheet ducts are a key component of ventilation and air conditioning systems in various building types, including commercial complexes, office buildings, residences, and hospitals. Currently, during the duct splicing process, especially when performing interlocking seams, it is crucial to ensure that the butt joint edges of the two steel sheets are tightly fitted and perfectly aligned. Otherwise, problems such as weak seams, air leaks, or duct deformation may occur.

[0003] A rectangular metal duct closure seam compaction machine with Chinese patent number CN207628903U has a simple structure, reasonable design, easy operation, and good performance. In the process of closing and sealing the rectangular metal duct, it not only achieves single-port and double-port seam sealing by bending down the locking edge, but also eliminates the interlayer gap between the single-port and double-port, blocks the escape route of the medium inside the duct, and improves the tightness of the rectangular metal duct body.

[0004] Existing operating methods mostly rely on manual pressing and fixing with simple tools, which is not only inefficient, but also difficult to provide continuous and uniform clamping force manually due to the elasticity of galvanized steel sheets. This can easily lead to unstable product quality due to the steel sheet springing open or shifting during the sewing process, increasing the labor intensity and safety risks for workers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a clamping device for sewing galvanized steel sheet ducts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for stitching galvanized steel sheet ducts, comprising a duct body with stitched edges at the corners, an electric guide rail slidably mounted inside the duct body, multiple sets of second universal wheels fixedly connected to the bottom end of the electric guide rail, a slide table slidably connected to the electric guide rail, a telescopic plate fixedly connected to the top end of the slide table, a support plate fixedly connected to the movable end of the telescopic plate, and the top end of the support plate abutting against the inner wall of the duct body, a base plate slidably connected to the side end of the duct body, a first universal wheel fixedly connected to the bottom end of the base plate, a telescopic rod fixedly connected to the top end of the base plate, an adjusting plate rotatably connected to the top end of the telescopic rod, a vibrator fixedly connected to the bottom end of the adjusting plate, a pressure plate connected to the output end of the vibrator, and the pressure plate contacting the stitched edge.

[0007] As a further technical solution of this utility model, a hydraulic rod with a foot pedal is installed between the bottom of the movable end and the fixed end inside the telescopic plate. A groove is opened on the side of the fixed end of the telescopic plate, and the foot pedal of the hydraulic rod extends through the groove to the outside of the telescopic plate.

[0008] As a further technical solution of this utility model, a second screw hole is provided above the fixed end of the telescopic rod, and a plurality of first screw holes corresponding to the second screw hole are provided at equal intervals on the side end of the movable end of the telescopic rod. Screws are connected to the internal threads of the first screw hole and the second screw hole.

[0009] As a further technical solution of this utility model, a U-shaped groove is provided at the top of the movable end of the telescopic rod, and the adjusting plate is threadedly connected to the inner wall of the U-shaped groove by bolts.

[0010] As a further technical solution of this utility model, both the slide and the base plate are made of strong magnetic material, and the slide and the base plate attract each other.

[0011] As a further technical solution of this utility model, a nut is fixedly connected to the output end of the vibrator, and a third screw hole is opened at the top of the pressure plate, and the pressure plate is threadedly connected to the third screw hole through the nut.

[0012] As a further technical solution of this utility model, the length of the support plate is greater than the length of the slide table, and the pressure plate is located at the center above the support plate.

[0013] As a further technical solution of this utility model, a controller for controlling the electric guide rail and the vibrator is fixedly connected to the slide.

[0014] This utility model provides a clamping device for sewing galvanized steel sheet ducts, which has the following advantages compared with the prior art:

[0015] This design discloses a clamping device for seaming galvanized steel sheet ducts. First, an electric guide rail is placed inside the duct body, fitting against the inner wall near the seam edge. This causes the support plate to also fit against the inner wall of the duct body, with part of the support plate inside. A foot pedal drives a hydraulic rod to extend and retract the telescopic plate, adjusting it until it contacts the top wall of the duct body. Next, a base plate is placed outside the duct body, magnetically attracting it to the sliding table. A first universal wheel at the bottom increases stability. The adjusting plate is then rotated so that the pressure plate faces the top center of the seam edge, maintaining balance. After adjustment, it is fixed with bolts. Finally, the telescopic rod is raised and lowered to adjust the pressure plate until it contacts the seam edge. Finally, screws are used to secure it. The corresponding first and second screw holes are threaded and fixed. At this time, the electric guide rail and vibrator can be turned on by the controller, so that the vibrator drives the pressure plate to strike up and down to press the top of the seam edge. During the pressing, the support plate is driven to move horizontally by the electric guide rail, and the magnetic connection between the slide table and the base plate can drive the pressure plate to move synchronously to achieve continuous operation. If the side of the seam edge is to be pressed, the adjustment plate can be rotated to turn the pressure plate toward the side of the seam edge, and the height of the telescopic rod can be adjusted again. At this time, the side of the seam edge can be pressed. When pressing the seam edge of the galvanized steel air duct body, the pressure plate automatically strikes and presses, and cooperates with the internal support plate to ensure that the deformation of the air duct body can be avoided due to the increase of the force points during the striking process.

[0023] Please see Figure 1 and Figures 3-4 A hydraulic rod 6 with a foot pedal is installed between the bottom of the movable end and the fixed end inside the telescopic plate 4. A groove 5 is provided on the side of the fixed end of the telescopic plate 4, and the foot pedal of the hydraulic rod 6 extends through the groove 5 to the outside of the telescopic plate 4. A second screw hole is provided above the fixed end of the telescopic rod 9. Multiple first screw holes 14 corresponding to the second screw hole are provided at equal intervals on the side of the movable end of the telescopic rod 9. Screws 15 are threadedly connected to the first screw holes 14 and the second screw holes. A U-shaped groove 17 is provided at the top of the movable end of the telescopic rod 9, and the adjusting plate 10 is threadedly connected to the inner wall of the U-shaped groove 17 by bolts 18.

[0024] Please see Figures 2-3 Both the slide table 3 and the base plate 8 are made of strong magnetic material, and the slide table 3 and the base plate 8 attract each other. The output end of the vibrator 11 is fixedly connected to a nut. The top of the pressure plate 12 has a third screw hole, and the pressure plate 12 is threadedly connected to the third screw hole through the nut. The length of the support plate 7 is greater than the length of the slide table 3. The pressure plate 12 is located at the center above the support plate 7. A controller for controlling the electric guide rail 2 and the vibrator 11 is fixedly connected to the slide table 3.

[0025] The working principle of this utility model is as follows: First, the electric guide rail 2 is placed inside the duct body 1 and fits against the inner wall near the seam edge 13, so that the support plate 7 also fits against the inner wall of the duct body 1. At this time, part of the support plate 7 is located inside the duct body 1. The hydraulic rod 6 can be driven by stepping on the foot pedal to extend and retract the telescopic plate 4, adjusting the support plate 7 to contact the inner top wall of the duct body 1. Then, the bottom plate 8 is placed on the outside of the duct body 1 so that it is magnetically attracted to the slide table 3, and the bottom is stabilized by the first universal wheel 16. Then, the adjusting plate 10 is rotated so that the pressure plate 12 faces the top middle position of the seam edge 13 to maintain balance. After adjustment, it is fixed by bolts 18. At this time, the telescopic rod 9 is raised and lowered to adjust the pressure plate 12 to contact the seam edge 13. After adjustment, it is fixed by screws 15 with the corresponding first screw hole 14 and second screw hole threads. At this time, it can be opened and closed by the controller. The electric guide rail 2 and vibrator 11 are activated, causing the vibrator 11 to drive the pressure plate 12 to strike up and down, pressing the top of the seam edge 13. During the pressing process, the electric guide rail 2 drives the support plate 7 to move horizontally, and through the magnetic connection between the slide table 3 and the base plate 8, the pressure plate 12 can be moved synchronously to achieve continuous operation. If pressing the side of the seam edge 13, the adjustment plate 10 can be rotated to turn the pressure plate 12 toward the side of the seam edge 13, and the height of the telescopic rod 9 can be adjusted again. At this time, the side of the seam edge 13 can be pressed. When the pressure plate 12 is damaged due to long-term use, it can be unscrewed from the output end of the vibrator 11 for replacement. With the above technical solution, when pressing the seam edge 13 of the galvanized steel duct body 1, the pressure plate 12 automatically strikes and presses, and cooperates with the internal support plate 7 to ensure that the deformation of the duct body 1 can be avoided during the striking process due to the increase of the force points.
