Abstract
The utility model discloses an expanding mill at an end of a steel pipe, comprising a base, a supporting disc and a main oil cylinder. The circle center of the supporting disc is provided with a cone-shaped block which is connected to the main oil cylinder. The outer wall of the cone-shaped block is further provided with a plurality of fan-shaped blocks which form a circle. The fan-shaped block is further provided with a module. The supporting disc is provided with a plurality of reset oil cylinder. The reset oil cylinder is connected to the module. The diameter of the circle formed by a plurality of fan-shaped blocks is 3.3m to the maximum. The end part of the cone-shaped block is provided with a blocking nut which is used for fixing the cone-shaped block and the main oil cylinder. The supporting disc and the main oil cylinder are fixedly connected to the upper part of the base. The expanding mill is advantageous in that the structure is simple; the use is convenient; the expansion force is large; the range of expanding and withdrawing of the expanding mill is large; the expanding mill is suitable for expanding the end of a sewer pipe.
Description
Technical field:
The utility model relates to steel pipe processing and handles and use field of mechanical technique, particularly a kind of steel tube head expanding machine.
Background technology:
Expanding machine is a kind of plant equipment that the UOE production process is eliminated steel pipe briquetting pressure and welding stress that is used for, and he produces oil, natural gas, the plant equipment that dedicated pipe such as coal gas are indispensable.The expanding machine of present stage, it is identical with girth to be mainly used in the pipe end shape that makes two steel pipes to be welded, for example; Wherein a steel pipe is promptly drawn together its pipe end to consistent with the pipe end of another root steel pipe to be welded, afterwards with expanding machine because of compressive deformation in the transportation; Can two steel pipes are integrally welded, so the steel tube head expanding machine of present stage is mainly used in oil; Natural gas, the hole enlargement welding of gas piping.Hole enlargement for sewer pipe is then undesirable; The hole enlargement requirement of sewer pipe; Wherein the diameter of the pipe end of a steel pipe expands to the pipe end that can comprise another steel pipe; That is, the pipe end of another steel pipe requires in the pipe end of the steel pipe after the complete insertion hole enlargement, and the maximum hole enlargement to 2.5 of the expanding machine of present stage meter.This just plays the hole enlargement requirement less than sewer pipe far away.In view of this technical problem, it is a kind of simple in structure, easy to use to press for appearance, the expansion great efforts, and hole enlargement harmomegathus weight range is big, is fit to a kind of steel tube head expanding machine of the pipe end hole enlargement of application sewer pipe.
Summary of the invention:
The purpose of the utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, the expansion great efforts, and hole enlargement harmomegathus weight range is big, is fit to a kind of steel tube head expanding machine of the pipe end hole enlargement of application sewer pipe.
To achieve these goals, the utility model provides a kind of steel tube head expanding machine, comprises base, supporting disk and master cylinder; Wherein, the home position of said supporting disk is provided with the taper piece, and said taper piece is connected with said master cylinder; The outer wall of said taper piece further is provided with some secter pats; Some secter pats constitute circle jointly, further are provided with module on the said secter pat, and said supporting disk is provided with some drawback cylinders; Said drawback cylinder links to each other with said module, and the diameter of a circle maximum that said some secter pats constitute is 3.3 meters.
The end of said taper piece is provided with locking nut, and said locking nut is used and fixedly taper piece and master cylinder, and said supporting disk and said master cylinder are fixedly connected on the top of base.
The pipe end that the utility model is used for the steel pipe of sewer is socketed in module, withstands on the supporting disk, and during the master cylinder motion, taper piece spreading; The taper piece drives the secter pat spreading, and secter pat drives the module spreading, then; The diameter of a circle that is made up of secter pat has enlarged, and behind the locking nut locking taper piece, the circle that secter pat is constituted keeps the diameter after the expansion; After a period of time, pipe end has promptly been accomplished hole enlargement, when resetting; Drawback cylinder push module on the supporting disk, module promotes secter pat, secter pat extruding taper piece homing.The corresponding module of drawback cylinder.The diameter of a circle that some secter pats constitute is returned to original state, and steel pipe takes off from module.The socket of sewer pipe can have been carried out.
The advantage of the utility model does, and is simple in structure, easy to use, the expansion great efforts, and hole enlargement harmomegathus weight range is big, is fit to use the pipe end hole enlargement of sewer pipe.Be specially:
Maximum gauge after the hole enlargement of traditional steel tube head expanding machine is 2.5 meters, only is applicable to oil, and the hole enlargement of natural gas and gas piping welding is not suitable for plugging together after the hole enlargement of sewer pipe.And the maximum gauge to 3.3 of the utility model after improving meter is particularly useful for the hole enlargement of drain pipe, and the harmomegathus weight range is big.
