Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe forming machines, in particular to a vertical double-wall corrugated pipe forming machine. Background Art

[0002] The mold for double-wall corrugated pipe is the core component of the double-wall corrugated pipe forming machine. Each double-wall corrugated pipe forming machine integrates thirty-six to forty-two pairs of precision forming molds. The key link in its efficient operation is to ensure that each pair of molds can be accurately aligned at the moment of mold closing. This is not only the key to improving production efficiency, but also a key challenge to breaking through production bottlenecks and accelerating production line flow.

[0003] Currently, all double-wall corrugated pipe forming machines rely on manual adjustment during the mold closing process to correct for minor misalignments. Subsequent mechanical positioning during production relies on built-in locating pins and sleeves. However, this rigid positioning method often subjects the slide and mold to unnecessary impact forces, leading to a chain reaction of mold deformation and slide damage, severely impacting equipment stability and production efficiency.

[0007] Wherein, the position detection device includes a proximity switch and a detection member matched with the proximity switch, the proximity switch is arranged on the sprocket toggle mechanism, and the detection member is arranged on the mold running platform.

[0008] Among them, the sprocket toggle mechanism includes a rotating shaft rotatably arranged on the mold operating platform and a sprocket module sleeved on the rotating shaft. The sprocket module is used to toggle the toggle roller to move the sliding seat along the operating track, and the proximity switch is arranged on the sprocket module.

[0009] The left and right ends of the sliding seat are respectively provided with the shifting rollers for rotation, the sprocket module includes two sprockets, the two sprockets are respectively used to shift the corresponding shifting rollers, and the proximity switch is provided on one of the sprockets.

[0010] The mold operation platform includes two mounting plates spaced apart on the left and right sides, the sprocket shifting mechanism is arranged between the two mounting plates, and the detection member is arranged on the corresponding mounting plate corresponding to the proximity switch.

[0011] Wherein, rollers are respectively provided at the left and right ends of the sliding seat, and the running track includes track grooves correspondingly provided on the inner sides of the two mounting plates, and the rollers are constrained in the corresponding track grooves.

[0012] Wherein, the left and right ends of the sliding seat are respectively provided with mounting shafts, and the roller and the shifting roller are both rotatably provided on the mounting shafts.

[0027] The sprocket driving mechanism 6 in this embodiment includes a rotating shaft 61 rotatably arranged on the mold operating platform 1 and a sprocket module sleeved on the rotating shaft 61.
