Description

[0002] In the pipe processing, the pipe end forming machine plays a crucial role. It can perform various processing on the ends of pipes, such as flaring, shrinking, and flanging, to meet different industrial application requirements. The feeding assembly, as the key part of the pipe end forming machine that accurately feeds the pipe to the forming station, directly affects the accuracy and efficiency of pipe end forming.

[0003] Existing tube end forming machine pusher components often have some shortcomings. For example, the pusher precision is not high enough, and it is impossible to make full-range fine adjustments to the position of the tube. This can easily lead to a large positional deviation of the tube when it enters the forming mold, making it difficult to guarantee the dimensional accuracy of the formed tube end and resulting in a high scrap rate. The pusher process is not stable enough. Existing pusher methods mostly use a top plate to directly push one end of the tube. The tube may shake or shift during the pusher process, which not only affects the processing quality but may also damage the equipment.

A first knob 15 is fixedly connected to one end of the first threaded rod 16.

[0026] In this design, the present invention adopts a design that allows for full-range fine-tuning of the cross-sectional coordinates at both ends of the pipe 5, thereby avoiding a large positional deviation when the pipe 5 enters the forming mold, which would otherwise result in a high scrap rate.

[0027] like Figures 1 to 6 As shown, in a specific embodiment, a clamping mechanism is provided at the upper end of the first base 1. The clamping mechanism includes a second fixing ring 10. Four second threaded blocks 23 are evenly fixedly connected to the second fixing ring 10. The second threaded blocks 23 have threaded holes inside.

A backlash pad 24 is fixedly connected to one end of the inner side of the clamping plate 21. A second knob 13 is fixedly connected to one end of the outer side of the second threaded rod 14.

[0028] In this setup, by clamping and fixing one end of the pipe 5 during the push, it is possible to effectively prevent the pipe 5 from shaking or shifting during the pushing process, which could affect the processing quality or damage the equipment.

[0029] like Figures 1 to 6 As shown, in a specific embodiment, an upper turntable 19 is fixedly connected to the lower outer periphery of the first fixed ring 9. A T-shaped groove 27 is provided inside the upper turntable 19. A T-shaped head 28 is movably sleeved inside the T-shaped groove 27. A lower turntable 20 is fixedly connected to the lower end of the T-shaped head 28. The lower end of the lower turntable 20 is fixedly connected to the upper surface of the first base 1 and the second base 2 respectively.

[0030] In this setup, the upper turntable 19 and the lower turntable 20 are designed to prevent the pipe 5 from bending when adjusting its position, thus protecting the quality of the pipe 5.

[0031] like Figures 1 to 6 As shown, in a specific embodiment, a slider 22 is fixedly connected to the lower outer periphery of the second fixing ring 10. A sliding hole is provided inside the slider 22, and a sliding rod 25 is movably sleeved inside the sliding hole. A slider groove 30 is provided inside the first base 1. The slider groove 30 corresponds to the slider 22 and is movably sleeved with it. The two ends of the sliding rod 25 are fixedly connected to the two ends of the slider groove 30.

[0032] In this setup, rotating the second knob 13 on the second fixing ring 10 clamps the other end of the pipe 5 via the clamping plate 21.

[0033] like Figures 1 to 6As shown, in a specific embodiment, a slot 4 is provided on one inner end of the first base 1, and a plug 29 is fixedly connected to one inner end of the second base 2. The plug 29 corresponds to the slot 4 and is movably inserted into it. Slide strips 3 are fixedly connected to both sides of the plug 29. The slide strips 3 correspond to the sliding grooves opened on the inner side of the slot 4 and are slidably inserted into it. A second hydraulic cylinder 11 is fixedly sleeved inside the plug 29. The end of the telescopic rod of the second hydraulic cylinder 11 is fixedly connected to the inner side of the slot 4.

[0034] In this setup, the distance between the first base 1 and the second base 2 can be adjusted by extending and retracting the second hydraulic cylinder 11 according to the length of the pipe.

[0036] In this setup, once the adjustment is complete, the first hydraulic cylinder 8 can be activated to extend its telescopic rod, which in turn pushes the pipe 5 towards the pipe end forming mold 31 via the top plate 12 to perform the pipe end forming operation.

[0037] like Figures 1 to 6 As shown, in a specific embodiment, a first fixing block 6 is fixedly connected to the upper surface of one outer end of the second base 2, and a pipe end forming mold 31 is fixedly installed on the inner side of the first fixing block 6. The pipe end forming mold 31 corresponds to the center position of the pipe 5.

[0038] In this setup, when using this device, first pass the pipe 5 through the first fixing ring 9 and the second fixing ring 10, then rotate the first knob 15 on the first fixing ring 9, and use the grooved roller 18 to hold and position the pipe 5. At the same time, finely adjust both ends of the pipe 5 to align it with the pipe end forming mold 31 and place it on the same horizontal line.

[0039] The implementation principle of the pusher assembly of the tube end forming machine in this embodiment is as follows:

[0040] This utility model adopts a design that allows for full-range fine-tuning of the cross-sectional coordinates at both ends of the pipe 5, thus avoiding large positional deviations when the pipe 5 enters the forming mold, which would result in a high scrap rate. At the same time, by clamping and fixing one end of the pipe 5 during the pushing process, it can effectively prevent the pipe 5 from shaking or shifting during the pushing process, thereby affecting the processing quality or damaging the equipment.

[0041] When using this equipment, first pass the pipe 5 through the first fixing ring 9 and the second fixing ring 10. Then rotate the first knob 15 on the first fixing ring 9 to hold and position the pipe 5 through the grooved roller 18. During this process, manually adjust the groove position of the grooved roller 18 to align with the arc surface of the pipe 5. At the same time, finely adjust both ends of the pipe 5 to align with the pipe end forming mold 31 and place them on the same horizontal line. Then rotate the second knob 13 on the second fixing ring 10 to clamp the other end of the pipe 5 through the clamping plate 21. During this process, the distance between the first base 1 and the second base 2 can be adjusted by extending and retracting the second hydraulic cylinder 11 according to the length of the pipe. After adjustment, the first hydraulic cylinder 8 can be started to extend its telescopic rod and push the pipe 5 towards the pipe end forming mold 31 through the top plate 12 to perform the pipe end forming operation.
