Abstract
The invention relates to the technical field of seamless steel pipe manufacturing equipment, in particular to a pipe rolling mill for manufacturing seamless steel pipes. The pipe rolling mill comprises an upper supporting seat and a lower supporting seat. The upper supporting seat and the lower supporting seat are arranged in a mirror manner, two upper upright columns which are parallel to each other and perpendicularly downwardly extend are arranged on the upper supporting seat, two lower upright columns which are parallel to each other and perpendicularly upwardly extend are arranged on the lower supporting seat, and the two upper upright columns correspond to the two lower upright columns; an upper roll is arranged between the two upper upright columns in a connected manner, a lower roll is arranged between the two lower upright columns in a connected manner, the upper roll and the lower roll are arranged in a mirror manner, gaps are reserved between the upper roll and the lower roll, the seamless steel pipes can pass through the gaps, and angles are formed between the axis of the upper roll or the axis of the lower roll and the axes of the seamless steel pipes. The pipe rolling mill for manufacturing the seamless steel pipes has the advantages that seamless pipelines with different diameter dimensions can be rolled by the aid of the pipe rolling mill, and the seamless pipelines with each type of diameter dimensions are high in yield.
Description
Technical field
The present invention relates to the technical field of seamless steel pipe production, especially a kind of production seamless steel pipe pipe mill.
Background technology
Seamless steel pipe has hollow section, and a large amount of pipeline being used as conveying fluid, as transfer oil, natural gas, coal gas, water and some solid material etc.Seamless steel pipe compared with the solid steel such as round steel, under identical bending resistance torsional strength, the lighter in weight of seamless steel pipe; Meanwhile, seamless steel pipe is also widely used in manufacturing structure part and machine components, and as the steel scaffold etc. in oil drill rocker, truck drive shaft, bicycle rack and construction, stock utilization is high, and manufacturing process is simple and easy, and machining period reduces.
Just because of the particularity of seamless steel pipe purposes, therefore, need to use various production equipment in the production process of seamless steel pipe, pipe mill is exactly produce one very important in seamless steel pipe equipment.But the pipe mill of existing majority exists certain defect in structural design, the caliber of these pipe mill institute rollings seamless steel pipe out differs, and product rejection rate is higher, causes the significant wastage of resource.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the prior art Problems existing in above-mentioned background technology, there is provided a kind of and produce seamless steel pipe pipe mill, can roll out the seamless pipeline of different-diameter size, and the yield rate of the seamless pipeline of each diameter dimension is higher.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production seamless steel pipe pipe mill, there is upper support seat and the lower support seat of mirror image setting, described upper support seat is provided with two to be arranged in parallel and the upper pillar stand extended all vertically downward, described lower support seat is provided with two to be arranged in parallel and the lower pillar stand extended all vertically upward, two described upper pillar stands and the position of two lower pillar stands mutually corresponding; Topping roll is connected with between two upper pillar stands, bottom roll is connected with between two lower pillar stands, described topping roll and bottom roll mirror image are arranged, there is the gap that can hold seamless steel pipe and pass, the axis of topping roll or all there is angle between the axis of bottom roll and the axis of seamless steel pipe between topping roll and bottom roll.
For the ease of two upper pillar stands being risen or declining, so that topping roll is risen or declines, therefore the upper surface of described upper support seat is provided with two upper cylinders, upper screw rod is connected with between two described upper cylinders, the top outer of two upper pillar stands is respectively arranged with upper support frame, and the upper surface of two described upper support frames is provided with the upper hoisting ring be connected with upper screw rod.
For the ease of two lower pillar stands being risen or declining, so that bottom roll is risen or declines, therefore the lower surface of described lower support seat is provided with two lower cylinders, lower screw mandrel is connected with between two described lower cylinders, the bottom outside of two lower pillar stands is respectively arranged with lower support frame, and the lower surface of two described lower support framves is provided with the lower hoisting ring be connected with lower screw mandrel.
The invention has the beneficial effects as follows: production seamless steel pipe pipe mill of the present invention, by automatically regulating the distance between topping roll and bottom roll, to reach the seamless pipeline rolling out different-diameter size, and the yield rate of the seamless pipeline of each diameter dimension is higher, and economic utilization rate is high.
