Description

Technical Field

[0001] This utility model relates to the field of pipe forming equipment technology, and in particular to an automated flat round pipe forming equipment. Background Technology

[0002] In the flat and round tube manufacturing industry, automated forming equipment is the core equipment for improving production efficiency and ensuring product consistency. In existing technologies, such as the "Automatic Forming Equipment for Flat and Round Spiral Air Ducts" with application number CN218192187U, although the automatic forming of flat and round air ducts is achieved, it still has many limitations in practical applications: the feeding mechanism of this equipment uses an inclined storage box with intermittent feeding components, relying on the material's own weight to slide down for feeding. It is prone to feeding deviation due to changes in the amount of material stored. Moreover, the size of the storage trough is fixed, and the storage box needs to be disassembled and replaced when changing to pipes of different diameters and lengths, resulting in long changeover times and difficulty in adapting to flexible production needs. At the same time, its clamping and limiting structure lacks pressure feedback and adaptive adjustment functions, and the movement of the clamping components is not guided or constrained. Therefore, there is an urgent need for an automated forming equipment for flat and round tubes that improves feeding accuracy, multi-specification compatibility, clamping stability, and intelligent collaboration to solve the pain points of existing technologies. Utility Model Content

[0003] The purpose of this invention is to provide an automated flat round tube forming device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Design an automated flat round tube forming device, including a forming host, a feeding mechanism and a limiting mechanism. The feeding mechanism is located outside the feeding port of the forming host, and the limiting mechanism is located on both sides inside the forming host. A forming cylinder is provided at the upper end of the forming host, and a forming mold is connected to the piston end of the forming cylinder. The feeding mechanism includes a mounting base, a motor, a threaded rod, a movable plate, a first cylinder, and a pusher plate. The mounting base has a movable groove on its inner side. The motor is fixed at the bottom of the movable groove and the drive end is connected to the threaded rod. The movable plate is slidably located outside the movable groove and is screwed to the threaded rod. The first cylinder is fixed outside the mounting base and the piston end is connected to the pusher plate.

[0005] Preferably, the limiting mechanism includes a fixed base, a second cylinder, an outer clamping plate, a pressure sensor, and an inner clamping plate. The fixed base is symmetrically fixed on both sides inside the molding host. The second cylinder is horizontally fixed inside the fixed base. The outer clamping plate is fixed to the piston end of the second cylinder. The pressure sensor is embedded in the inner wall of the outer clamping plate. The inner clamping plate is detachably connected to the inside of the pressure sensor.

[0006] Preferably, the feeding mechanism further includes an outer baffle, which is symmetrically welded to the bottom of the outer side of the mounting base. A rubber buffer pad is attached to the inner side wall of the outer baffle, and the movable plate is slidably connected to the outer baffle.

[0007] Preferably, a first guide rod is fixed in the movable groove on both sides of the mounting base, and a guide slider is fixed on both sides of the movable plate, the guide slider being slidably connected to the first guide rod.

[0008] Preferably, a positioning seat is fixed to the outside of the first cylinder, a positioning rod is slidably inserted into the positioning seat and the inner end of the positioning rod is fixed to the pusher plate, and an extension plate is fixed to the lower end of the pusher plate.

[0009] Preferably, the limiting mechanism further includes a guide seat and a second guide rod. The guide seat is fixed on both sides of the second cylinder, and one end of the second guide rod is fixedly connected to the outer wall of the outer clamping plate, while the other end passes through the guide seat and is slidably sleeved with the guide seat.

[0010] Preferably, the molding host is further provided with a controller, and the pressure sensor and the second cylinder are electrically connected to the controller.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a feeding mechanism within the device. An electric motor drives a threaded rod to rotate, which in turn causes a movable plate to rise and fall vertically along a first guide rod and an outer baffle. A first cylinder drives a pusher plate to extend and retract, thereby lifting the pipe and pushing it to the lower end of the forming mold. This enables automatic feeding of the pipe to be formed, reducing the labor intensity of manual pipe handling and lowering the risk of damage due to human error. It also allows for precise control of the pipe's lifting height and pushing position, ensuring stable connection between the pipe and the lower end of the forming mold, preventing feeding deviations that could affect forming accuracy.

[0012] 2. This utility model features a limiting mechanism within the device. A second cylinder drives the outer clamping plate to extend and retract along the second guide rod. The two sets of outer clamping plates move in opposite directions and contact the pipe through the inner clamping plate. A pressure sensor monitors the clamping pressure, enabling adaptive pressure clamping and real-time adjustment of the clamping force on the pipe to be formed. This helps avoid pipe deformation, damage, or slippage caused by excessive or insufficient clamping force, effectively ensuring the forming quality of the flat round pipe. Furthermore, it can adapt to pipes of different wall thicknesses and materials, greatly improving the equipment's compatibility with multiple pipe specifications.

[0018] In this embodiment, the limiting mechanism 3 includes a fixed base 31, a second cylinder 32, an outer clamping plate 33, a pressure sensor 34, and an inner clamping plate 35.

The motor 23 drives the threaded rod 24 to rotate, which drives the movable plate 25 to rise and fall vertically along the first guide rod 26 and the outer baffle 211 to the specified height. The first cylinder 28 drives the pusher plate 29 to extend and retract, and with the help of the extension plate 291 for positioning, pushes the tube to the lower end of the forming mold 12 in the forming host 1. Then, the second cylinder 32 of the limiting mechanism 3 drives the outer clamping plate 33 to move in opposite directions along the second guide rod 322, and the inner clamping plate 35 contacts the tube. The pressure sensor 34 monitors the clamping force in real time and transmits it to the controller of the forming host 1.
