Description

Technical Field

[0001] The utility model belongs to the technical field of pipe bending machines, in particular to a pipe bending machine. Background Art

[0002] Copper tubes, also known as red copper tubes, are pressed and drawn seamless tubes. They possess excellent electrical and thermal conductivity, making them the primary material for conductive and heat dissipation components in electronic products. They are also highly corrosion-resistant and resistant to oxidation. Tube bending machines are often required for copper tube production. Existing tube bending machines typically bend individual copper tubes sequentially using a rotating shaft. This method can only bend a single tube, resulting in low efficiency and increased loading and unloading times. Furthermore, bending a single copper tube consumes significant energy, increasing production costs. Therefore, we propose a new tube bending machine. Utility Model Content

[0003] The purpose of the present utility model is to provide a pipe bending machine, which can place multiple copper pipes at the same time by setting a bending component, specifically a placing table top. After the placement is completed, the motor is started to drive the turntable to rotate slowly counterclockwise, and the turntable drives the bending plate to flip through the connecting shaft. The bending plate pushes multiple copper pipes at the same time and cooperates with the bending auxiliary roller to bend the copper pipes. The bending angle of the copper pipe can be adjusted by rotating the turntable to different positions. This method can bend multiple copper pipes at the same time, which not only improves work efficiency and reduces energy consumption of equipment, but also reduces the production cost of copper pipes, and solves the problem that the existing pipe bending machine can only bend once, which is not only inefficient, but also increases the number of loading and unloading times of the staff. At the same time, bending a single copper pipe consumes more equipment energy consumption and increases production costs.

[0026] The bending assembly 12 includes a bending plate 121, which is arranged on the right side of the placement table 11. The top of the copper tube 15 is in contact with a bending auxiliary roller 122. The outer side of the bending auxiliary roller 122 is provided with a plurality of annular grooves, which are adapted to the copper tube 15. The back of the workbench 1 is fixedly connected to a fixing seat 123, the back of the fixing seat 123 is fixedly connected to a motor 124, and the front output end of the motor 124 is fixedly connected to a turntable 125. The front and back sides of the bending plate 121 are fixedly connected to a connecting shaft 211. The back side of the connecting shaft 211 at the rear is fixedly connected to the front side of the turntable 125. By setting the bending assembly Part 12, specifically, multiple copper tubes 15 can be placed on the top of the placement table 11 at the same time. After the placement is completed, the motor 124 is started to drive the turntable 125 to rotate slowly counterclockwise. The turntable 125 drives the bending plate 121 to flip through the connecting shaft 211. The bending plate 121 pushes multiple copper tubes 15 at the same time and cooperates with the bending auxiliary roller 122 to bend the copper tube 15. The bending angle of the copper tube 15 can be adjusted by rotating the turntable 125 to different positions. This method can bend multiple copper tubes 15 at the same time, which not only improves work efficiency and reduces energy consumption of equipment, but also reduces the production cost of the copper tube 15.

[0027] The front and back sides of the bending auxiliary roller 122 are fixedly connected to support blocks 221, the bottom of the support block 221 is fixedly connected to the top of the workbench 1, and arc frames 126 are provided on the outside of the two connecting shafts 211. The bottom of the arc frames 126 is fixedly connected to the top of the workbench 1. The connecting shaft 211 will slide in the arc frames 126 during movement, making the bending plate 121 more stable when flipping.

[0028] The bottom of the bending plate 121 contacts the top of the workbench 1, and there is a gap between the left side of the bending plate 121 and the right side of the placement table 11. The outer surface of the connecting shaft 211 contacts the inner wall of the arc frame 126. Since there is a gap between the bending plate 121 and the placement table 11, it will not affect the flipping of the bending plate 121.

[0029] A pressing assembly 13 is provided on the left side of the bending auxiliary roller 122. The pressing assembly 13 includes a pressing plate 131. A rubber pad is fixedly connected to the bottom of the pressing plate 131. A fixing frame 132 is provided in front and behind the pressing plate 131. One end of the bottom of the fixing frame 132 is fixedly connected to the surface of the workbench 1. The rubber pad at the bottom of the pressing plate 131 contacts the surface of the copper tube 15. The pressing plate 131 will move downward under the elastic action of the spring 134, thereby pressing the copper tube 15 to simply fix it, thereby preventing the copper tube 15 from deflecting or falling off.

[0030] Two limiting vertical rods 133 are fixedly connected to the top of the pressure plate 131, and a spring 134 is sleeved on the outside of the limiting vertical rod 133. The top of the limiting vertical rod 133 passes through the fixing frame 132 and extends to the outside. The limiting vertical rod 133 is slidably connected to the fixing frame 132, and the top of the spring 134 is fixedly connected to the top of the inner side of the fixing frame 132. The bottom of the spring 134 is fixedly connected to the top of the pressure plate 131. The limiting vertical rod 133 at the top of the pressure plate 131 slides in the fixing frame 132 to limit the pressure plate 131. The rubber pad at the bottom of the pressure plate 131 can prevent the copper tube 15 from being scratched.

[0031] A positioning plate 14 is provided on the left side of the pressing component 13, and a support rod 141 is fixedly connected to the center of the left side of the positioning plate 14, and a vertical plate 142 is fixedly connected to the top left side of the workbench 1, and the support rod 141 slides through the vertical plate 142 and extends to the outside, and a bolt knob 143 is threadedly connected to the internal thread of the vertical plate 142, and the bottom of the bolt knob 143 contacts the top of the support rod 141, and the right side of the positioning plate 14 contacts the left side of the copper tube 15. By setting the positioning plate 14, specifically by turning the bolt knob 143 counterclockwise to release the fixation of the support rod 141, the positioning plate 14 can be pushed and pulled to adjust the position. After the adjustment is completed, the bolt knob 143 is turned clockwise to make it contact with the support rod 141 to fix the positioning plate 14, thereby adjusting the positioning position to meet the different bending requirements of the copper tube 15.

[0032] A specific application of this embodiment is:

[0033] The cam 132 is pressed against the support 131 and the support 133 is pressed against the support 132, and the support 133 is pressed against the support 131. In conjunction with the bending of the copper tube 15, the connecting shaft 211 will slide in the arc frame 126 during movement, making the bending plate 121 more stable when flipping, and the bending angle of the copper tube 15 can be adjusted by rotating the turntable 125 to different positions. When the bending is completed, the motor 124 is started to drive the turntable 125 to reset, and the bending plate 121 is reset, and the staff can take out the copper tube 15. This method can bend multiple copper tubes 15 at the same time, which not only improves work efficiency and reduces energy consumption of equipment, but also reduces the production cost of the copper tube 15. When it is necessary to bend the copper tube 15 at different positions, the bolt knob 143 is turned counterclockwise to release the fixation of the support rod 141, and the positioning plate 14 can be pushed and pulled to adjust the position. After the adjustment is completed, the bolt knob 143 is turned clockwise to make it contact with the support rod 141 to fix the positioning plate 14, thereby adjusting the positioning position to meet the different bending requirements of the copper tube 15.
