Description

Technical Field

[0001] The utility model relates to the technical field of plastic-lined composite steel pipe production equipment, in particular to a plastic-lined composite steel pipe vertical online cutting device. Background Art

[0002] The steel-plastic composite pipe is a steel pipe with a plastic pipe inside and a steel pipe structure on the outside. This structure has many advantages. On the one hand, it has the function of a plastic pipe and can be used to transport hot water or other liquids. Plastic is corrosion-resistant and can insulate. However, since plastic pipes are very soft, they cannot meet the requirements in places where high strength is required. Therefore, adding a steel pipe to the outer end of the plastic pipe can solve these problems well.

[0003] Steel-plastic composite pipes have good corrosion resistance and pressure bearing capacity, and can transport water and gas. The existing complete set of steel-plastic composite pipe production lines cut the plastic pipe when threading the pipe to facilitate the insertion of the lock of the pipe threading machine. This process is all done manually with a knife, which has low work efficiency and increases labor and costs. Utility Model Content

[0018] like Figure 1-3 As shown, a plastic-lined composite steel pipe vertical online cutting device for plastic pipes comprises a base frame 1 and a support frame 2 installed on the base frame 1.

[0019] A guide frame 3 is connected to one side of the support frame 2, and a lifting assembly is provided below the guide frame 3. The bottom of the lifting assembly is hinged to the base frame 1, and the top of the lifting assembly is hinged to the slide 4. The lifting assembly includes a cylinder 6, and the bottom and the top of the piston end of the cylinder 6 are respectively hinged to the bottom of the base frame 1 and the slide 4 through a hinge assembly. The hinge assembly includes a cylinder pull ring 7 connected to the base frame 1 and the slide 3, and the bottom and the top of the piston end of the cylinder are respectively hinged to the two cylinder pull rings 7 through a pin 8.

[0020] The slide plate 4 is slidably connected in a slide groove provided on the guide frame 3 , and a cutting knife 5 is connected to the top of the slide plate 4 via a mounting assembly.

[0021] The mounting assembly includes a fixing block 9 mounted on the top of the slide plate 4 by bolts. The fixing block 9 is provided with two symmetrically arranged fixing holes 10 , and the cutting knife 5 is mounted in the fixing holes 10 .

[0022] A retaining ring 11 is connected to the top of the support frame 2 , and the plastic tube passes through the retaining ring 11 .

[0023] The action process of the utility model is as follows:

[0024] When in use, the device is placed between the plastic tube cutting device and the stacking device. The plastic tube is driven forward by the cutting device. At this time, the piston end of the cylinder 6 extends, so that the cutting knife 5 is placed behind the retaining ring 11. Then the front end of the plastic tube passes through the retaining ring 11, and the cutting knife 5 cuts the advancing end of the plastic tube into four parts. Then the piston end of the cylinder 6 retracts, and the cutting knife 5 no longer cuts the plastic tube. After the cut plastic tube is taken away by the stacking device, the piston end of the cylinder 6 extends to reset the cutting knife 5.

[0025] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
