Description

Technical Field

[0001] This utility model relates to the field of cold bending device technology, specifically a spiral tube cold bending device. Background Technology

[0002] Spiral tube cold bending machines can bend pipes or round rods into profiles of a certain spiral shape and size at room temperature, so that aluminum profiles can better meet different usage needs and achieve the expected usage effect. Therefore, cold bending and shaping is an essential process in the production of aluminum profiles.

[0003] Existing cold bending equipment cannot be pressed well during use, and manual pressing may still be required during bending. At the same time, because the pressing arc is not on the same plane, it will cause excessive bending and forming. In addition, multiple models cannot be bent multiple times during the bending process, which wastes time and manpower. Utility Model Content

[0004] The purpose of this invention is to provide a spiral tube cold bending device that can solve the problems of poor limiting and clamping of spiral tubes during bending and the inability to complete bending in a single operation rather than multiple operations simultaneously.

[0005] To achieve the above objectives, a spiral tube cold bending device is provided, comprising a base, a worktable arranged above the base, symmetrically arranged slide grooves at the top of the worktable, a first motor arranged inside the base, the output shaft of the first motor being fixedly connected to a rotating shaft, a support frame symmetrically arranged at the top of the base, a plurality of cylinders arranged at the top of the support frame, a pressure plate being fixedly connected to the telescopic shaft of the cylinders, slide rails symmetrically arranged at the top of the worktable, a fixing block arranged at the top of the slide rails, an electric push rod arranged on the side of the fixing block, and a clamping block being fixedly connected to one end of the electric push rod.

[0006] A second motor is provided on the inner side of the chute. A threaded rod is fixedly connected to the output shaft of the second motor. A threaded block is threadedly connected to the outer surface of the threaded rod. A bearing is provided at one end of the threaded rod. A limit rod is provided on the inner side of the chute. A base plate is fixedly connected to the top of the threaded block. A pressure roller is fixedly connected to the top of the base plate.

[0007] According to the spiral tube cold bending device, the worktable is circular and installed above the first motor.

[0008] According to the spiral tube cold bending device, the support frame is installed on the side of the workbench.

[0009] According to the spiral tube cold bending device, the support frame is installed above the pressure plate, and the pressure plate is installed above the slide rail.

[0010] According to the spiral tube cold bending device, the threaded block is installed on the inner side of the slide groove.

[0011] According to the spiral tube cold bending device, the pressure roller is mounted above the threaded block.

[0012] According to the spiral tube cold bending device, the outer surface of the limiting rod is slidably connected to the threaded block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This spiral tube cold bending device, by setting up a worktable and a first motor, can realize the rotation of the worktable, thereby enabling the spiral tube to bend at multiple angles. A support frame, cylinders, and pressure plates are set up to fix the spiral tube on the worktable. Multiple cylinders are set up so that they can work separately during the pressing of the spiral tube, allowing for multiple bends at once, and enabling bending of different types of spiral tubes. Slide rails, electric push rods, and clamping blocks are set up to clamp the spiral tube during bending, fixing it to the worktable and improving bending accuracy. Multiple clamping devices are set up to limit and clamp spiral tubes of different profiles on the worktable, while avoiding the problem of uneven bending due to different heights causing the pressing arcs to be not on the same plane, thus affecting the over-bending forming.

[0015] 2. This spiral tube cold bending device, by setting a second motor, a threaded rod, a threaded block, and a limiting rod, can make the pressure roller move in the slide groove to achieve bending of the spiral tube at different angles, improve service quality, and meet the diverse needs of customers.
