Description

Technical Field

[0001] This utility model belongs to the field of bending technology, specifically relating to a bending device for building metal fittings. Background Technology

[0002] Bending metal fittings is a common operation in metal processing, mainly used to bend metal materials into the required shape according to design requirements. It is widely used in steel structures, pipe supports, metal frames, and other fields in the construction industry. The purpose of bending is to ensure that metal fittings meet the dimensional and installation requirements of the building structure.

[0003] Problems with existing technology: Existing metal bending machines for building components typically place a matching block at the folded edge to fill the folded metal sheet and prevent deformation of the folded edge due to tension during bending. However, placing the matching block manually is very troublesome, and manual placement requires the hand to be close, which can easily lead to the hand being pinched, or the placement position may be off-center, causing severe deformation of the metal sheet, resulting in scrap and waste.

[0004] The purpose of this utility model is to provide a bending device for building metal fittings. The design of the disassembly outer wheel can replace manual insertion of filler, increasing work efficiency. At the same time, the setting of the limiting teeth inside the built-in tube can replace different disassembly outer wheels to adapt to metal plates with different widths and folded edges. Meanwhile, the design of the fixed guide component can also clamp and guide the plate to be bent after replacement, so that it can always be kept at the same horizontal position as the disassembly outer wheel.

[0005] The specific technical solution adopted by this utility model is as follows: A bending device for building metal fittings includes: a workbench, a bending post fixedly installed on the top of the workbench, a rotating bending component provided on one side of the bending post, a fixed guide component provided on the other side of the bending post, a plate to be bent being clamped inside the fixed guide component, and the plate to be bent extending to the middle position between the bending post and the rotating bending component.

[0006] An inner support column is vertically slidably arranged inside the built-in tube. A screw is rotatably connected to the top of the inner support column, and a protruding cap is fixedly connected to the end of the screw.

[0007] One end of the limiting tooth is rotatably connected to the inner tube, and the other end of the limiting tooth is set as a protrusion on the side near the inner support column, and the protrusion contacts the inner support column. The side of the limiting tooth near the disassembled outer wheel is inserted between the anti-rotation teeth.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1 As shown, a bending device for building metal fittings includes: a workbench 5, a bending post 1 fixedly installed on the top of the workbench 5, a rotating bending component 3 provided on one side of the bending post 1, and a fixed guide component 2 provided on the other side of the bending post 1. The fixed guide component 2 holds a plate 4 to be bent inside the fixed guide component 2, and the plate 4 to be bent extends to the middle position between the bending post 1 and the rotating bending component 3.

[0017] In this process, the bending assembly 3 rotates around the bending post 1 to bend the plate to be bent 4. The fixed guide assembly 2 is used to restrict the movement of the plate to be bent 4, and at the same time, the plate to be bent 4 is clamped so that the center line of the plate to be bent 4 is consistent with the center line of the bending post 1.

[0018] See attached document Figure 2 - Figure 5The rotating bending assembly 3 includes a U-shaped connecting frame 301, which is rotatably mounted to the bending stationary column 1. A sliding block 303 is slidably mounted on the bottom of the U-shaped connecting frame 301, and a disassembly outer wheel 304 is provided on the top of the sliding block 303. A hydraulic press 305 is fixedly connected to the side of the U-shaped connecting frame 301 away from the bending stationary column 1. The output end of the hydraulic press 305 passes through the U-shaped connecting frame 301 and is fixedly connected to the sliding block 303. An inner tube 306 is rotatably connected to the top of the sliding block 303. The disassembly outer wheel 304 is sleeved on the outside of the inner tube 306. Limiting teeth 310 are arranged in an array inside the inner tube 306. The disassembly outer wheel 304 corresponds to the limiting teeth 310. The position has a groove, and multiple anti-rotation teeth 309 are fixedly installed in an array inside the groove; an inner support column 311 is vertically slidably arranged inside the inner tube 306, and a screw is rotatably connected to the top of the inner support column 311. A protruding cap 308 is fixedly connected to the end of the screw; one end of the limiting tooth 310 is rotatably connected to the inner tube 306, and the other end of the limiting tooth 310 is set as a protrusion on the side near the inner support column 311, and the protrusion contacts the inner support column 311. The side of the limiting tooth 310 near the disassembly outer wheel 304 is inserted into the position between the anti-rotation teeth 309; the top of the inner tube 306 has an array of rotating grooves 307, and the outer side of the protruding cap 308 also has an array of rotating grooves 302.

[0019] According to the above structure, when bending a metal plate with folded edges, first select the appropriate disassembly outer wheel 304 according to the width of the metal plate, and at the same time adjust the fixing guide component 2 to clamp it. A motor is provided below the corresponding bending fixed column 1 of the U-shaped connecting frame 301. The motor is used to drive the U-shaped connecting frame 301 to rotate. It can also be manually rotated to bend the plate 4 to be bent. When it is necessary to replace or disassemble the outer wheel 304, the output end is retracted by the hydraulic press 305, and the fixing block 204 is slid to a position close to the rotating screw 205. Then, a metal rod is inserted into the rotating groove 302 and the rotating groove 307, and the inner tube 306 and the protruding cap 308 are rotated relative to each other, so that the protruding cap 308 is raised through the threaded connection. When the protruding cap 308 is raised, the inner support column 311 also separates from the protruding limit tooth 310. At this time, one end of the limit tooth 310 loses its limit. When the outer wheel 304 is disassembled and moved upward, the limit tooth 310 will rotate into the inner tube 306, and the outer wheel 304 can be disassembled and removed. The U-shaped connecting bracket 301 is set as a ring at the position corresponding to the disassembled outer wheel 304 to facilitate the installation, removal and replacement of the outer wheel 304. During installation, the outer wheel 304 of the plate to be bent 4 is fitted into the middle position of the inner tube 306. Then, while slightly rotating, the protruding cap 308 is rotated to lower the inner support column 311 and make contact with the protruding limit tooth 310. The thrust of the inner support column 311 pushes the limit tooth 310 into the anti-rotation tooth 309, thereby limiting the outer wheel 304. Among them, the limiting tooth 310 is located in the middle of the built-in tube 306, and the groove corresponds to the middle of the disassembly outer wheel 304.

[0020] See attached document Figure 6 - Figure 7 The fixed guide assembly 2 includes a baffle 201. A clamping screw 202 is provided on the side of the baffle 201 away from the plate to be bent 4. A fixing block 204 is fixedly connected to both ends of the baffle 201 corresponding to the clamping screw 202. The fixing block 204 is rotatably connected to the clamping screw 202. Both ends of the clamping screw 202 are vertically threaded and connected to a threaded clamping slider 203. A groove is vertically opened on the baffle 201 corresponding to the position of the threaded clamping slider 203. The threaded clamping slider 203 extends to the outside of the groove and is fixedly connected to a vertical clamping plate 207. The threaded clamping slider 203 is slidably installed with the groove. A longitudinal clamping plate 206 is slidably installed on the side of the two vertical clamping plates 207 that are close to each other. A rotating screw 205 is provided on the side of the two longitudinal clamping plates 206 that are far from each other. The rotating screw 205 is rotatably connected to the vertical clamping plate 207 and threadedly connected to the longitudinal clamping plate 206.

[0021] According to the above structure, when the plate to be bent 4 is replaced, the shell rotates the clamping screw 202 to make the threaded clamping slider 203 slide. Since the threads at both ends of the clamping screw 202 are opposite, the threaded clamping sliders 203 can only move closer or further apart when rotating. The middle position of the clamping screw 202 is at the same horizontal height as the groove and the limiting tooth 310. The plate to be bent 4 can be clamped by the vertical clamping plate 207. The longitudinal clamping plate 206 is threadedly connected to the rotating screw 205. When the folding edge of the plate to be bent 4 changes, the distance between the longitudinal clamping plate 206 and the baffle 201 can be changed by rotating the rotating screw 205 to adapt to the width of the folding edge.

[0022] The working principle of this utility model is as follows: When bending a metal plate with folded edges, firstly, select a suitable disassembly outer wheel 304 according to the width of the metal plate, and simultaneously adjust the fixing guide assembly 2 to clamp it; when it is necessary to replace the disassembly outer wheel 304, the output end is retracted by the hydraulic press 305, the fixing block 204 is slid to a position close to the rotating screw 205, and then a metal rod is inserted into the first rotating groove 302 and the second rotating groove 307, and then the inner tube 306 and the protruding cap 308 rotate relative to each other, so that the protruding cap 308 is raised through the threaded connection. When the protruding cap 308 is raised, the inner support column 311 also separates from the protruding limit tooth 310. One end of the limiting tooth 310 loses its limiting position. When the outer wheel 304 moves upward, the limiting tooth 310 will rotate into the inner tube 306, and the outer wheel 304 can be removed. The U-shaped connecting bracket 301 is set as a ring corresponding to the position of the outer wheel 304 for easy loading and unloading and replacement of the outer wheel 304. During installation, the outer wheel 304 adapted to be bent plate 4 is placed in the middle position of the inner tube 306. Then, while slightly rotating, the protruding cap 308 is rotated to lower the inner support column 311 and make contact with the protrusion of the limiting tooth 310. The pushing force of the inner support column 311 inserts the limiting tooth 310 into the anti-rotation tooth 309, thereby limiting the outer wheel 304.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
