Abstract
The invention relates to a hot rolling repair machine for a pipeline. The entire mandrel surface is plated with chrome, and the outer surface of a roll is of an elliptic structure, so that the defects of the surface of the pipeline wall are avoided, the service life of the pipeline is prolonged, and economic benefits are significant.
Description
Technical field
The present invention is the equipment of oilfield waste and old oil passageway reparation usefulness, is that machine is repaired in a kind of oil pipe hot rolling.
Background technology
After the operation of the oil pipe that oil pumping in oil fields is used through a pump detection period, part oil pipe can form the light defects such as a large amount of pockmarks, impression, raggle because of reasons such as eccentric wear, corrosion at tube wall surface, this part oil pipe is because self existing defective can't continue the use of going into the well, but these light defects not yet reach again the degree that oil pipe is scrapped, process the mode that this part exists the oil pipe of light defects generally can take to seal up for safekeeping in the oil field, but after sealing certain time limit up for safekeeping, can scrap because of reasons such as the oil pipe surface oxidisation are serious, cause a large amount of wastes.
Summary of the invention
The objective of the invention is to design a kind of oil pipe hot rolling and repair machine, there are light defects in the oil field but the oil pipe that not yet reaches the degree of scrapping heats, repairs processing, eliminate its blemish, in the service life of prolongation oil pipe, the while is the reduce processing cost again.
The object of the present invention is achieved like this: be comprised of drive motors, mandrel, shaft coupling, roll, roll chock, medium-frequency heating coil, conveying roller, bed body, the bed body fixes on the ground, conveying roller, motor are connected on the body, motor is connected with roll by shaft coupling, roll is installed on the lathe bed with certain angle by roll chock, medium-frequency heating coil is installed in the front end of roll, and the chromium plating of mandrel surface integral is processed.
The roll outer surface adopts oval structure.
The invention has the beneficial effects as follows: exist the oil pipe of light defects to be delivered to medium-frequency heating coil by conveying roller and heat, then the oil pipe after will heating is fed forward to roll, by the roll driven rotary and the power that continues to move ahead is provided, utilize the defective of the acting in conjunction elimination tube wall surface of roll and mandrel, thereby realize prolonging the oil pipe purpose in service life, but the service life of oval-shaped structure Effective Raise roll, mandrel after integral surface chromium plating is processed can effectively reduce the frictional resistance that oil pipe moves ahead under the prerequisite that guarantees product quality, reduce production costs, so the present invention has significant economic benefit.
Description of drawings
Fig. 1 is the overall construction drawing of the embodiment of the invention.
Fig. 2 is the roll structure figure of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described.
Formed by drive motors 1, mandrel 2, shaft coupling 3, roll 4, roll chock 5, medium-frequency heating coil 6, conveying roller 7, bed body 8, bed body 1 fixes on the ground, conveying roller 7, motor 1 are connected on the body 8, drive motors 1 is connected with roll 4 by shaft coupling 3, roll 4 is installed on the body 8 with certain angle by roll chock 5, medium-frequency heating coil 6 is installed in the front end of roll 4, mandrel 2 surface integral chromium plating are processed, and can effectively reduce the frictional resistance that oil pipe moves ahead under the prerequisite that guarantees product quality
