[0031] The running track in this embodiment includes a forming section 231, a mold opening section 232, an upstream return section 233, a quick return section 234 and a downstream return section 235 which are connected in sequence to form a ring. The sliding seats 3 on the downstream return section 235, the forming section 231, the mold opening section 232 and the upstream return section 233 are closely arranged. The main driving device is used to drive the sliding seats 3 on the downstream return section 235, the forming section 231, the mold opening section 232 and the upstream return section 233 to slide at a speed of V1. A quick return device 6 is also provided on the platform body 2.

[0033] Specifically, the forming section driving mechanism includes a forming section driving motor 11, a forming section reducer 12 and a forming section driving gear set 13.

[0036] Specifically, the sending module includes a plurality of sending components arranged at intervals, and the sending components include a sending shaft 61 rotatably arranged on the top plate 21 and the bottom plate 22 through a bearing and a sending gear 62 fixedly arranged on the sending shaft 61 for engaging with the sliding seat 3 to send the sliding seat 3. All the sending shafts 61 are arranged in parallel, and one of the sending shafts 61 is connected to the sending drive mechanism in transmission. At the same time, all the sending shafts 61 are synchronously rotated through the transmission mechanism.

[0037] The transmission mechanism may be one of a gear transmission mechanism, a chain transmission mechanism and a belt transmission mechanism. Since the gear transmission mechanism has high precision, the transmission mechanism in this embodiment is preferably a gear transmission mechanism.

[0038] Specifically, the gear transmission mechanism includes multiple first transmission gears 63 and multiple groups of gear transmission assemblies. The first transmission gears 63 are arranged one by one on the sending shaft 61; the gear transmission assembly is arranged correspondingly between two adjacent sending shafts 61, and the gear transmission assembly includes a mounting shaft 64 fixedly set on the base plate 22 and a second transmission gear 65 rotatably set on the mounting shaft 64 through a bearing. The mounting shaft 64 is arranged parallel to the sending shaft 61, and the second transmission gear 65 is meshed with the two adjacent first transmission gears 63.

[0039] The sending driving mechanism in this embodiment includes a sending reducer 66 disposed on the bottom plate 22 and a sending driving motor 67 disposed on the sending reducer 66. The sending driving motor 67 is used to drive the sending reducer 66 to operate. The sending reducer 66 is connected to the sending shaft 61 in the middle of the sending module. In practical applications, it is not limited to which sending shaft 61 the sending reducer 66 is connected to, and it can be selected according to actual conditions, and this embodiment does not limit this.

[0040] Since the servo motor can control the speed and the position accuracy is very accurate, the feeding drive motor 67, the forming section drive motor 11 and the return section drive motor 14 in this embodiment are preferably servo motors.

The sensing member in this embodiment adopts a sensing plate, which is disposed in the middle position of the sliding seat 3. In actual applications, the structural form of the sensing member is not limited.

[0043] During production, the forming section driving motor 11 drives the forming section driving gear set 13 to operate, and the forming section driving gear set 13 drives the sliding seat 3 on the forming section 231 to slide at a speed of V1.

[0044] like Figure 4As shown, when the exit-end in-position detection switch 8 on the quick return section 234 detects that the sliding seat 3 has moved into position from the exit of the quick return section 234 (the sliding seat 3 is disengaged from the transmission gear 62 at the exit of the quick return section 234 and does not move), the transmission gear 62 at the entry of the quick return section 234 is engaged with the to-be-transferred sliding seat 3 at the entry of the quick return section 234, and the transmission drive motor 67 drives the transmission gear 62 to operate, and the transmission gear 62 transmits the to-be-transferred sliding seat 3 to be rapidly moved toward the exit of the quick return section 234 at a speed of V2; as shown in FIG. Figure 5 As shown, when the entry-in-place detection switch 7 at the entry end of the quick return section 234 detects the next sliding seat 3 to be moved, the last moved sliding seat 3 pushes the stationary sliding seat 3 downstream thereof to abut against the sliding seat 3 on the downstream return section 235, and the shifting drive motor 67 drives the shifting gear 62 to decelerate, and the shifting gear 62 shifts the sliding seat 3 on the quick return section 234 to make the sliding seat 3 run at a speed of V1, completing a quick shifting action of the sliding seat 3.

[0045] In summary, the forming mold operating platform and the corrugated pipe forming machine of the present invention make their structures more flexible by setting up a quick return section and a quick return device. Not only can the forming section be arbitrarily lengthened without increasing the forming mold, thereby achieving the purpose of producing high-quality pipes, but also the cost is controlled and the expenditure is reduced. It is worthy of industrial promotion and use.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the protection scope of the present invention.
