In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0033] like Figures 1 to 8 In the specific embodiment shown, the present invention discloses an automatic pipe bending equipment, including a frame 10, a conveying mechanism 20 arranged on the frame 10, a lifting mechanism 30 connected to the frame 10, a pipe bending rack 40 connected to the frame 10 is located above the lifting mechanism 30, and a pipe bending mechanism 50 corresponding to the lifting mechanism 30 is provided on the pipe bending rack 40; the pipe bending mechanism 50 includes a pipe bending mounting plate 51 connected to the pipe bending rack 40, and a pipe bending assembly 52 and a moving assembly 53 connected to the pipe bending mounting plate 51; the pipe bending assembly 52 is slidably connected to the moving assembly 53.

[0034] Specifically, if Figures 5 to 7 As shown, the moving assembly 53 includes a moving cylinder fixing seat 531 and a slide rail 532 connected to the bend pipe mounting plate 51, a moving cylinder 533 connected to the moving cylinder fixing seat 531, and the slide rail 532 is arranged on the telescopic end side of the moving cylinder 533. The side of the slide rail 532 away from the moving cylinder 533 is also provided with a limit seat 534, and the limit seat 534 is connected to the bend pipe mounting plate 51. The side of the limit seat 534 close to the slide rail 532 is also provided with a top plate 535, and the lower end of the top plate 535 passes through the bend pipe mounting plate 51; the slide rail 532 is slidably connected to the bend pipe assembly 52.

[0035] Specifically, if Figures 5 to 7As shown, the bending pipe assembly 52 includes a sliding seat 521 slidably connected to the slide rail 532, a bending pipe cylinder 522 located at the upper end of the sliding seat 521, a bending pipe column 523 connected to the telescopic end of the bending pipe cylinder 522, and a clamp 524 connected to the bending pipe column 523; the clamp 524 is located at the bottom of the bending pipe mounting plate 51, and the lower end of the bending pipe column 523 passes through the sliding seat 521 and the bending pipe mounting plate 51 in sequence to be connected to the clamp 524, and the clamp 524 is used to connect with the workpiece 60 to be processed, and the straight pipe 61 on the workpiece 60 to be processed corresponds to the position of the top plate 535, and the top plate 535 is also provided with a groove 5351 corresponding to the straight pipe 61.

[0036] The limit seat 534 is further provided with a horizontal limit screw 5341 and a vertical adjustment screw 5342, and the vertical adjustment screw 5342 is connected to the upper end of the top plate 535. The clamp 524 is further provided with an annular groove 5241 for clamping the workpiece 60 to be processed.

[0037] Among them, in this embodiment, the moving cylinder 533 pushes the bending pipe assembly 52 to move back and forth on the slide rail 532 to cope with workpieces 60 to be processed of different sizes. The limit seat 534 is used to limit the bending pipe assembly 52 to prevent it from sliding out of the slide rail 532. Turning the horizontal limit screw 5341 can adjust the horizontal position of the bending pipe assembly 52 so that it is better in the bending area to ensure the quality of the bending pipe. Turning the vertical adjustment screw 5342 can adjust the upper and lower positions of the top plate 535 so that the groove 5351 corresponds to the straight pipe 61 on the workpiece 60 to be processed of different heights. When the lifting mechanism 30 lifts the workpiece 60 to be processed, the workpiece 60 to be processed is clamped with the annular groove 5241 on the fixture 524. At this time, the straight pipe 61 is in the groove 5351, and then the bending cylinder 522 contracts to drive the bending column 523 to move upward. At this time, the fixture 524 and the workpiece 60 to be processed are subjected to an upward force, and the groove 5351 on the top plate 535 bends the straight pipe 61 of the workpiece 60 to be processed into a bent pipe under the action of the reaction force. The bending efficiency is high and it is convenient for operators to install and debug. This structure will not cause the pipe to be stuck in the bending assembly 52 due to sudden power failure.

[0038] Furthermore, in this embodiment, the groove 5351 imitates the shape of a tube and can completely fit the surface of the straight tube 61, thereby better protecting the surface of the straight tube 61 while ensuring the effect of bending the tube.

[0039] Specifically, if Figures 5 to 7As shown, a stripping assembly 70 is also provided at the bottom of the elbow mounting plate 51, and the stripping assembly 70 is located on both sides of the clamp 524; the stripping assembly 70 includes a stripping cylinder 71 connected to the elbow mounting plate 51, and a stripping block 72 connected to the telescopic end of the stripping cylinder 71, and the stripping block 72 corresponds to the position of the annular groove 5241 on the clamp 524.

[0040] Among them, in this embodiment, the clamp 524 is located at the upper end position of the annular groove 5241 and is also provided with a notch groove 5242, and the front end of the stripping block 72 is located in the notch groove 5242. When the workpiece 60 to be processed completes the bending of the pipe, the stripping cylinder 71 starts to work, driving the stripping block 72 to move downward. At this time, the stripping block 72 moves downward from the notch groove 5242, and the workpiece 60 to be processed is separated from the annular groove 5241 and moved to the conveying mechanism 20.

[0041] Among them, such as Figure 8 As shown, the structure of the workpiece 60 after the bending is completed, the straight tube 61 located outside the workpiece 60 has been bent.

[0042] In this embodiment, the workpiece 60 to be processed is a compressor housing, but is not limited to a compressor housing.

[0043] Specifically, if Figures 3 and 4 As shown, the lifting mechanism 30 includes a lifting mounting plate 31 connected to the frame 10, a lifting cylinder 32 and a plurality of linear bearings 33 connected to the lifting mounting plate 31, a lifting guide rod 34 connected to the linear bearing 33, a lifting plate 35 connected to the lifting guide rod 34, and a lifting cylinder 36 connected to the lifting plate 35; the upper end of the lifting guide rod 34 passes through the lifting mounting plate 31 and the linear bearing 33 from bottom to top and is connected to the lifting plate 35, the telescopic end of the lifting cylinder 32 passes through the lifting mounting plate 31 and is connected to the lifting plate 35, and the telescopic end of the lifting cylinder 36 is also connected to a bent pipe lifting plate 37, and the bent pipe lifting plate 37 corresponds to the position of the clamp 524.

[0044] Among them, a lifting mounting plate 38 is also provided on both sides of the lifting plate 35, and the outer side of the lifting mounting plate 38 is also slidably connected to a limit cylinder 39, and the telescopic end of the limit cylinder 39 is also connected to a stopper 391, and the stopper 391 corresponds to the position of the clamp 524.

[0045] Among them, when the telescopic end of the jacking cylinder 32 moves upward, the jacking plate 35 is pushed upward, and the jacking guide rod 34 and the linear bearing 33 play a guiding role. When the jacking plate 35 rises to the highest position, the jacking cylinder 36 starts to work, and pushes the elbow jacking plate 37 upward, so that the workpiece to be processed 60 located on the elbow jacking plate 37 is connected to the fixture 524. In the process of lifting the elbow jacking plate 37 upward, the limit cylinder 39 is adjusted according to the rising height of the elbow jacking plate 37, and the stop block 391 is connected to the workpiece to be processed 60 to ensure that the workpiece to be processed 60 will not move in position during the rising process, and ensure that the workpiece to be processed 60 can correspond to the fixture 524.

[0046] Furthermore, in this embodiment, the stopper 391 is located on one side of the workpiece 60 to be processed and is in an arc shape, so as to prevent scratches on the surface of the workpiece 60 to be processed and better fix the workpiece 60 to be processed.

[0047] In this embodiment, the number of the lifting guide rods 34 and the number of the linear bearings 33 are the same, both being four, which are evenly distributed on the lifting mounting plate 31 , so that the force is evenly applied and the guiding effect is good.

[0048] Specifically, if Figures 1 to 2 As shown, the conveying mechanism 20 includes a power component 21 connected to the frame 10, and a conveyor belt 22 connected to the power component 21. The position of the conveyor belt 22 corresponds to the position of the clamp 524, which is convenient for conveying the workpiece 60 to be processed to the processing area, and also convenient for conveying the workpiece 60 to be processed after the bending is completed to the next process.

[0049] A cover 80 is further provided on the bent pipe frame 40 to provide protection.

[0050] Among them, in this embodiment, the number of the ejecting mechanism 30 and the bending mechanism 50 is 2, which are distributed adjacent to each other, which can ensure that they can be used for two different products without changing the model. It is also applicable to more than two products, ensuring that the equipment can be quickly changed without stopping or briefly pausing, thereby improving work efficiency.

[0051] In other embodiments, the number of the ejecting mechanism 30 and the bending mechanism 50 can also be 1 or more than 2 to adapt to different application scenarios.

[0052] The above examples are merely provided to further illustrate the technical content of the present invention for easier understanding by the reader, but do not limit the embodiments of the present invention to these examples. Any extension or re-creation of the technology based on the present invention is protected by the present invention. The scope of protection of the present invention shall be determined by the claims.
