Description

Technical Field

[0001] This utility model belongs to the field of metal wrought iron handrail processing, and in particular relates to a metal wrought iron handrail bending machine. Background Technology

[0002] The primary function of wrought iron handrails is to provide stable support for people going up and down stairs, reducing the risk of falls, which is especially important for the elderly, children, and those with mobility impairments. Wrought iron handrails come in a variety of designs and styles, not only meeting practical needs but also significantly enhancing the aesthetics of the staircase and the entire space, showcasing a noble and elegant ambiance.

[0003] Comparing with Chinese Patent No. CN221434512U, a metal wrought iron handrail bending machine is disclosed, including a main body mechanism. A protective mechanism is slidably connected to the outer end of the main body mechanism, and a positioning mechanism is slidably connected to the lower part of the protective mechanism. The protective mechanism includes a transmission component, and a protective cover is installed on the inner side of the transmission component. The protective cover has a U-shaped structure, and a movable cover is slidably connected to the inner end of the protective cover. Multiple evenly distributed adjusting rods are fixedly connected to the top of the movable cover. It can realize that by setting the movable cover and adjusting rods, the adjusting rods, in conjunction with the force of the spring, drive the movable cover to detach from the inner end of the protective cover, thereby allowing the protective cover to form a protective structure outside the workbench. Moreover, the protective structure is easy to retract and will not affect the bending work, and can effectively prevent workers from accidentally touching the bending components.

[0004] However, the aforementioned patent still requires personnel to operate within the bending area, which is less safe. Furthermore, during disassembly and loading, bending can only be stopped, greatly extending the preparation and auxiliary time. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a metal wrought iron handrail bending machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A metal wrought iron handrail bending machine includes a frame device for support and fixation, and an extrusion device mounted on the frame device for upper support and lower pressing for forming. A positioning device for dual-station rotating support and positioning of raw materials is provided in the middle of the extrusion device. The extrusion device includes a lower pressing component, and a supporting component is provided below the lower pressing component. The positioning device includes a rotating table component for supporting rotation, a motor is provided at the bottom of the rotating table component, and two lower templates are symmetrically mounted on the rotating table component.

[0008] Furthermore: the frame device includes a base plate, four columns are evenly arranged at the four corners of the base plate, a worktable is installed between the tops of the columns, a limit hole is provided on the worktable, and a fixing frame is provided behind the limit hole.

[0009] Furthermore, the base plate, the column, the workbench, and the fixing frame are welded together.

[0010] Furthermore: the pressing component includes a first cylinder, a connecting seat is installed at the bottom of the first cylinder, and an upper template is installed below the connecting seat; the supporting component includes two symmetrically arranged second cylinders, and a supporting bracket is installed between the tops of the second cylinders.

[0011] Furthermore: the upper template and the connecting seat are bolted together, and the support frame is square column-shaped.

[0012] Furthermore: the rotary table assembly includes a rotary table, on which two sets of positioning structures are symmetrically arranged. Each set of positioning structures includes four positioning blocks, and clearance holes are provided between the positioning blocks. The positioning blocks and the rotary table are riveted together.

[0013] Furthermore, a rectangular partition is provided in the middle of the rotating platform, which is bolted to the rotating platform to separate the two sets of positioning structures.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The dual-station rotary repositioning design avoids personnel operating near bending areas, thus improving safety;

[0016] 2. By setting up a dual-station repositioning and disassembly / loading system, disassembly / loading and bending / forming can be carried out simultaneously, reducing the auxiliary preparation time.

[0017] 3. By using a separate top support, the stress on the turntable is reduced, extending its service life. Attached Figure Description
