Abstract
The invention provides a special rolling machine for oil and natural gas pipelines, which relates to a rolling machine. The rolling machine comprises a bracket (1), a piston rod (2), an oil cylinder body (3), an upper roller pressing wheel (4), an upper roller (5), a balance oil cylinder (6) and a lower roller (7), wherein the oil cylinder body (3) is arranged on the bracket (1); the oil cylinder body (3) is connected with the piston rod (2); the upper roller pressing wheel (4) is arranged below the oil cylinder body (3); the upper roller (5) is arranged below the upper roller pressing wheel (4); the lower roller (7) is arranged below the upper roller (5); and the balance oil cylinder (6) is arranged at the bottom right part of the lower roller (7). A three-roller rolling machine is used, a supporting roller is used as the lower roller, and a reverse deformation method is used by the upper roller to eliminate the deflection deformation of the rollers in the rolling process; and an oil cylinder pressurizing mode is adopted at two ends of the upper roller, thereby effectively utilizing the space, increasing the utilization ratio of materials, greatly lowering the weight of overall equipment, having no need of turning over and resetting the bracket, and increasing the safety.
Description
Technical field:
The present invention relates to a kind of veneer reeling machine, relate in particular to special rolling machine for oil and natural gas pipelines.
Background technology:
Drawbacks such as at present the domestic preparation method that is used for slender pipelines such as oil, natural gas is to adopt the step compacting of forcing press JCOE fado basically, and ubiquity speed is slow, compacting low precision (multi-section circular arc), equipment have high input.Increase set round and alignment process in the operating process, complex operation, it is big to take plant area, and the input and output cycle is long.Particularly production line is subjected to the factory building layout restrictions more obvious.And common three rollers or four-roll plate bending machine since the influence of top roll distortion when rolling the overlength cylinder roll finished product and the pocket lip reflex occurs.
Summary of the invention:
The purpose of this invention is to provide special rolling machine for oil and natural gas pipelines, it adopts three rolls plate bending machine, and lower roll adopts carrying roller, and top roll employing reversible deformation method is eliminated the roller deflection deformation in the process of rolling; Top roll two ends pressuring method adopts the oil cylinder pressurization effectively to utilize the space, increases stock utilization, greatly reduce integral device weight, and security is good.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is made up of support 1, piston rod 2, cylinder block 3, last rolling wheel set 4, top roll 5, balancing cylinder 6 and lower roll 7, support 1 is provided with cylinder block 3, cylinder block 3 links to each other with piston rod 2, last rolling wheel set 4 is arranged on the below of cylinder block 3, top roll 5 is arranged on the below of rolling wheel set 4, and top roll 5 belows are provided with lower roll 7, and the lower right of lower roll 7 is provided with balancing cylinder 6.
Top roll of the present invention two ends pressuring method adopts the oil cylinder pressurization, and the oil cylinder piston bar is fixed, and cylinder block descends and exerts pressure to top roll, thereby effectively utilizes the space, increases stock utilization, greatly reduces integral device weight; Discharging of the present invention is from the inboard discharging of discharging support, and balancing cylinder is pushed down the top roll afterbody, makes the perk of the top roll other end, is convenient to the finished product discharging, and support need not overturning and resets, and has increased security.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
The structural representation of Fig. 2 during for discharging of the present invention.
The specific embodiment:
With reference to Fig. 1-2, this specific embodiment is by the following technical solutions: it by support 1, piston rod 2, cylinder block 3, go up rolling wheel set 4, top roll 5, balancing cylinder 6 and lower roll 7 and form, support 1 is provided with cylinder block 3, cylinder block 3 links to each other with piston rod 2, last rolling wheel set 4 is arranged on the below of cylinder block 3, top roll 5 is arranged on the below of rolling wheel set 4, and top roll 5 belows are provided with lower roll 7, and the lower right of lower roll 7 is provided with balancing cylinder 6.
Top, described top roll 5 two ends is provided with oil cylinder, adopts oil cylinder to pressurize.
Described lower roll 7 adopts carrying roller.
This specific embodiment top roll two ends pressuring method adopts the oil cylinder pressurization, and the oil cylinder piston bar is fixed, and cylinder block descends and exerts pressure to top roll, thereby effectively utilizes the space, increases stock utilization, greatly reduces integral device weight; The discharging of this specific embodiment is from the inboard discharging of discharging support, and balancing cylinder is pushed down the top roll afterbody, makes the perk of the top roll other end, is convenient to the finished product discharging, and support need not overturning and resets, and has increased security.
