Detailed Description

In the embodiment, referring to fig. 1 to 4, the pe gas pipe orifice correcting and rounding device is formed by connecting two horizontal ends of two frame-shaped lower lever frames 11 outside the two horizontal ends of two frame-shaped upper lever frames 4 through a pin shaft 3. The other ends of the two upper lever frames 4 are meshed and connected through two upper lever frame transmission teeth 4-1, and each upper lever frame transmission tooth 4-1 is provided with four teeth. The outer side surfaces of the two groups of upper lever frame transmission teeth 4-1 are connected with two symmetrical upper lever frame connecting plates 9 through a hinge connecting shaft 2 at the center of the upper lever frame transmission teeth 4-1. The other ends of the two lower lever frames 11 are meshed and connected through two lower lever frame transmission teeth 11-1, and each lower lever frame transmission tooth 11-1 is four teeth and corresponds to the upper lever frame transmission tooth 4-1. The outer sides of the two lower lever frame transmission teeth 11-1 are connected with two lower lever frame connecting plates 10 which are connected with the lower bottom plates 10-1 into a whole correspondingly to the two hinged connecting shafts 2. And two ends of a horizontal transmission screw rod 5 are in threaded connection with threaded holes in the two corresponding pin shafts 3. A positioning sleeve 5-4 is sleeved on the left side of a pin shaft 3 at the right end of a transmission screw 5, and a handle connecting rod 5-1 is fixed at the right end of the transmission screw 5 and the right side of the pin shaft 3 through a gasket 5-3 and a gasket 5-2. The right end of the handle connecting rod 5-1 is provided with an insertion hole of the rotating handle 1, and the rotating handle 1 is inserted in the insertion hole. The arc plates 7 with the parallel support frames 8 of the same specification are sleeved outside the two symmetrical upper lever frame connecting plates 9 and the one-piece lower lever frame connecting plate 10 in an up-down symmetrical mode, and the arc surfaces of the two arc plates 7 are enabled to be symmetrical outwards. A layer of cushion pad 6 made of rubber is fixed on the outer surface of the circular arc plate 7. The radian and the length of the arc plate 7 are designed into a plurality of specifications according to the caliber of the PE pipe, and the circle restorer is suitable for the PE pipe with the inner diameter of 110-315 mm.

The utility model has the advantages that the using method is as follows; firstly, cleaning the PE pipe orifice, and scraping the burrs and the shallow surface layer of the pipe orifice by using a scraper for the deformed PE pipe. The longest and shortest outside diameters of the pipe orifices are measured out by a ruler in a mutually perpendicular mode and marked at the shortest positions. Two correctors and a PE pipe same-caliber support frame 8 are respectively arranged on the outer side surfaces of an upper lever frame connecting plate 9 and a lower lever connecting plate 10 at the upper end and the lower end of an upper lever frame 4 and a lower lever frame 11, so that the correctors and the PE pipe are positioned on the same plane. And putting the contraction state correction rounder into the deformed PE pipe orifice.
