Description

Technical Field

[0001] The utility model belongs to the technical field of plastic corrugated pipe manufacturing equipment, in particular to a plastic double-wall corrugated pipe forming machine. Background Art

[0002] Plastic pipes have the advantages of reliable connection, good low-temperature impact resistance, good stress cracking resistance, good chemical corrosion resistance, good aging resistance, good wear resistance, good toughness, high pressure resistance and long service life. Compared with traditional pipes such as cast iron pipes and galvanized steel pipes, HDPE plastic pipes have significant advantages such as light weight, corrosion resistance, small water flow resistance, energy saving, easy and quick installation, and low cost. They are favored by the pipeline engineering industry and gradually replace traditional pipes.

[0003] The existing plastic double-wall corrugated pipe forming machine includes two symmetrically arranged forming platforms, such as Figure 1 As shown, multiple modules are running on the platform. The first platform P1 and the second platform P2 are both provided with a molding module M and a running track. The molding module is set on the running track through a sliding seat Z and runs along the track. When the molding module runs into the molding area of ​​the two platforms, the two molding modules M in opposite positions are molded to form a molding mold. The plastic corrugated pipe is molded in the molding area after passing through multiple molding molds. Among them, a servo motor is used as a power device to drive the molding module M to run on the first platform P1 and the second platform P2. The first platform P1 and the second platform P2 each use a servo motor, and the two are synchronized through electrical signals, so that the first platform P1 and the second platform P2 run synchronously. However, when the equipment suddenly loses power or the emergency stop switch is pressed in an emergency, due to the different braking inertia of the first platform P1 and the second platform P2, there will be a deviation in the position of the brake stop, and the module mismatch problem of the two sides will occur. When the power is supplied and restarted, it is necessary to deal with the synchronization problem of the two platforms. The adjustment procedure is relatively cumbersome when restarting again.
