Abstract
The utility model discloses a ring roll cylindrical mandrel precision cold rolling pipe mill. Rolls are in annular shapes, the two annular rolls are vertically symmetrically arranged on a frame, a cylindrical mandrel is arranged between the two annular rolls, a mandrel connection rod is connected to the left end of the cylindrical mandrel, the other end of the mandrel connection rod is fixed onto a connection rod clamping plate, a crank connection rod mechanism is connected with the frame, two meshed transmission gears are coaxially connected to the upper annular ring and the lower annular roll, the lower transmission gear is meshed with a rack on a base, and when the frame moves left and right, the rack is meshed with the lower transmission gear to drive the two transmission gears to rotate, thereby driving the two annular rolls to rotate. The ring roll cylindrical mandrel precision cold rolling pipe mill has the advantages that the mill increases working efficiency, prolongs service life of the rolls, increases geometric accuracy a rolled steel pipe, and greatly increases producing efficiency of the mill.
Description
Technical field
The utility model relates to a kind of cold pilger mill, the cylindrical plug precise cold of particularly a kind of ring roller pipe mill.
Background technology
It is 180 ° that the roll of traditional two-high cold-rolling pipe mill adopts semi-circular its central angle, and this concave roll is when the rolled pipe material, and active length is short, distortion is concentrated, the load that roll bears is big, the roller surface wearing and tearing are very fast, so the service life of roll is shorter, and the roll mandrel complex structure that cooperates with it, difficulty of processing is bigger, cost is higher, has increased production cost, also has this pass work housing motion parts weight bigger, reduce tube rolling speed, caused production efficiency to reduce greatly.
In addition, the plug of traditional two-high cold-rolling pipe mill adopts conic mandrel bar, use conic mandrel bar to increase the opening degree of roll, will increase along the inhomogeneities of roll periphery wall thickness, greatly reduce the geometric accuracy of rolled steel tube, when rolling inductile steel pipe, be easy to generate defectives such as crackle, when the tapering of plug is excessive, the tube reducing distortion mainly occurs in the pre-finishing part of roll, and at this moment metal has produced the processing hard defects, and excessive distortion meeting causes breaking of steel pipe in the operation of rolling, therefore must control feed, cause the production efficiency of pipe mill to reduce greatly.
Summary of the invention
The purpose of this utility model is that existing two-high cold-rolling pipe mill active length is short, distortion is concentrated in order to solve, roll service life is short and adopt conic mandrel bar to make these problems that institute's rolled steel tube breaks easily and the cylindrical plug precise cold of a kind of ring roller pipe mill that provides.
The used roll of the cylindrical plug precise cold of ring roller described in the utility model pipe mill is an annular, symmetry is located on the frame about two annular rolls, be provided with a column type plug between two annular rolls, the left end of column type plug connects a plug connecting rod, the other end of plug connecting rod is fixed on the connecting rod chuck, carriage left end near the connecting rod chuck is provided with the revolution feed mechanism, and carriage is provided with the liftout dolly, and the liftout dolly can be along the carriage move left and right.
There is a toggle to link to each other with frame, toggle drives frame left and right sides back and forth movement, be coaxially connected with two travelling gears with two annular rolls up and down, two travelling gears are meshed, following travelling gear is meshed with the tooth bar on being located at base, frame is when carrying out side-to-side movement, the engagement of tooth bar and following travelling gear drives two travelling gears and rotates, thereby driving two annular rolls rotates, carry out the rolling of steel pipe, toggle is driven by a belt wheel, and belt wheel is connected by belt or chain with driving wheel on the motor and links.
The course of work of the present utility model:
Steel pipe is when rolling, the pipe material is from passing through the liftout cart transport to close two annular roll location in the swivel feeding mechanism, this moment, the column type plug passed between two annular rolls from the pipe material, when the pipe material is fed between two annular rolls, two annular rolls begin to rotate under the driving of travelling gear expects to be rolled to pipe, under the acting in conjunction of two annular rolls and column type plug pipe is expected that rolling is fished pipe.
The beneficial effects of the utility model:
1, roll adopts annular roll, make the angle of revolution of roll in a rolling stroke can reach 270-300 °, the haul distance of work housing and the active length of roll have been increased, improved the deformation condition of institute's rolled steel tube, reduce the wearing and tearing of roll, also reduced the weight of work housing motion parts, thereby increased the speed of cold-rolling mill, improve operating efficiency, prolonged the service life of roll;
2, plug adopts cylindrical plug, can reduce the opening degree of roll, avoid inhomogeneities, improve the geometric accuracy of institute's rolled steel tube along ring-like peripheral wall thickness, when sending the pipe material to, bigger feed can be arranged simultaneously, greatly improve the production efficiency of pipe mill.
