Description

Technical Field

[0001] The utility model relates to the technical field of plastic composite pipe edge pressing, in particular to an edge pressing device for metal-plastic composite pipes. Background Technique

[0002] A composite pipe is a pipe formed by connecting two layers of pipes. The outer pipe has a larger diameter, and the inner pipe has a longer length. After the inner pipe is sleeved into the outer pipe, a die head first passes through the inner pipe for cold drawing, so that the inner pipe fits the inner wall of the outer pipe, restricting the relative movement between the two pipes. Finally, the excess parts at both ends of the outer pipe are edge pressed to make them turn outwards, achieving a stable fit.

[0003] During the use of the existing edge pressing device for metal-plastic composite pipes, the excess parts at both ends of the outer pipe are edge pressed. However, during edge pressing, due to the large variety of composite pipes, the edge pressing device cannot meet the edge pressing requirements of composite pipes with different wall thicknesses, making it inconvenient to use and reducing the practicability of the device.

Guide rods are slidably connected to both sides inside the connecting seat. A ball screw is connected to the middle inside the connecting seat, and a rotating motor is connected to the top of the ball screw.

[0007] Preferably, guide rails are symmetrically arranged inside the machine table, and sliding seats are installed outside the guide rails.

A limiting plate 3 is fixed on the clamping roller 2. The limiting plate 3 can limit one end of the composite pipe. And above the clamping roller 2, an edge pressing roller 4 is arranged. The edge pressing roller 4 can perform edge pressing treatment on the composite pipe. A support shaft 5 is connected inside the edge pressing roller 4. The support shaft 5 can support the edge pressing roller 4. One end of the support shaft 5 is fixed with an adjusting mechanism 6. The adjusting mechanism 6 includes a connecting seat 601 fixedly connected to the support shaft 5. The connecting seat 601 can install the support shaft 5. On both sides inside the connecting seat 601, a guide rod 602 is slidably connected. The guide rod 602 can guide the connecting seat 601. In the middle inside the connecting seat 601, a ball screw 603 is connected. The ball screw 603 can adjust the height of the connecting seat 601. And the top of the ball screw 603 is connected with a rotating motor 604. The rotating motor 604 can drive the ball screw 603 to rotate.

[0023] As Figures 1 - 2 shown, guide rails 7 are symmetrically arranged inside the machine table 1. A sliding seat 8 is installed outside the guide rails 7, enabling the sliding seat 8 to move horizontally along the guide rails 7.

[0024] As Figures 1 - 2 shown, a driving mechanism 9 is arranged at the top of the sliding seat 8. The driving mechanism 9 includes a rotating roller 901, a support plate 902 and a driving motor 903, facilitating the horizontal movement of the driving mechanism 9 driven by the sliding seat 8.

[0025] As Figures 1 - 2 shown, there are two groups of rotating rollers 901. And both groups of rotating rollers 901 are rotatably connected to the support plate 902, facilitating the support of the composite pipe by the rotating rollers 901 and driving the composite pipe to rotate.

[0026] As Figures 1 - 2 shown, one group of rotating rollers 901 is connected to the driving motor 903. And the driving motor 903 is installed on the support plate 902, enabling the driving motor 903 to drive one group of rotating rollers 901 to rotate.

[0027] As Figures 1 - 2 shown, on the side of the machine table 1 opposite to the adjusting mechanism 6, a pushing mechanism 10 is arranged. And the pushing mechanism 10 includes an electric push rod 1001 and a push plate 1002, facilitating the adjustment of the horizontal position of the composite pipe by the pushing mechanism 10.

[0030] The working principle of this device: When this device is in specific use, the staff places the composite pipe on the two rotating rollers 901 on the driving mechanism 9. After placement, the electric push rod 1001 in the pushing mechanism 10 drives the push plate 1002 to move. The push plate 1002 pushes the composite pipe and the sliding seat 8 to move horizontally along the guide rail 7 until the side of the composite pipe abuts against the limiting plate 3 on the clamping roller 2. After the adjustment is completed, the staff makes the rotating motor 604 in the adjusting mechanism 6 drive the ball screw 603 to rotate according to the wall thickness of the composite pipe. During the rotation of the ball screw 603, the connecting seat 601 is driven to move along the guide rod 602, thereby adjusting the distance between the edge pressing roller 4 and the clamping roller 2 to meet the edge pressing requirements of composite pipes with different wall thicknesses, facilitating use and improving practicability. During the edge pressing process, the driving motor 903 drives one of the rotating rollers 901 to rotate, and then the composite pipe can be driven to rotate to achieve the edge pressing treatment of the composite pipe.
