The device comprises a roll-in mechanism which consists of two in-parallel roll shafts and a driving device which drives the roll-in mechanism to run, wherein the roll shafts are provided with a plurality of annular roll-in grooves along the axial direction, two annular roll-in grooves on the two roll shafts correspond to each other one by one to form into a hole-shaped feed port, and the two roll shafts relatively rotate to perform the roll-in to the drawing part of the seamless steel tube which moves in a reciprocating way back and forth in the feed port. The roll-in device is reasonable in structure design and convenient to operate, the overall dimension of the drawing part of the seamless steel tube can meet the requirement of a follow-up drawing technology after the two roll shafts are used for performing the roll-in repeatedly, and the products with various specifications and wall thicknesses can be produced, so that the device is higher in practical applicability.
Description
Technical field
The utility model belongs to seamless steel pipe manufacturing technology field, relates in particular to the rolling device of seamless steel pipe drawing portion.
Background technology
Seamless steel pipe is to make hollow billet with steel ingot or the solid pipe hole that wears long, make through hot rolling, cold rolling or cold group then, a large amount of as the pipeline of carrying fluid, as pipeline of transfer oil, natural gas, coal gas, water and some solid material etc., its bending resistance torsional strength is big, in light weight, is a kind of economic cross-section steel, be widely used in manufacturing structure spare and machine components, as oil drill rocker, truck drive shaft etc.Seamless steel pipe forges and presses out one in its end heating and pulls out head before cold-drawn, is convenient to the drawing pipe fitting, differs bigger but forge and press the actual size and the technological requirement size of pulling out head of coming out usually, to the difficulty that increased of later stage steel pipe drawing operation.
Summary of the invention
Problem to be solved in the utility model just provides simple in structure, easy to operate seamless steel pipe drawing portion rolling device, can carry out the higher roll-in of precision to the head that pulls out of steel pipe, makes it can satisfy the requirement of later stage drawing process.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: seamless steel pipe drawing portion rolling device, it is characterized in that: the drive unit that comprises the roller press mechanism of forming by two roll shafts that are arranged side by side and can drive this roller press mechanism running, it is axially arranged with some roads annular roller indent the roll shaft upper edge, the steel pipe drawing portion that the corresponding one by one pass feeding mouth that forms of annular roller indent on two roll shafts, two roll shafts rotate in opposite directions to moving back and forth in feeding mouth carries out roll-in.
Further, described roll shaft is the cylinder axis structure.During practical operation, adopt the rotation mode that periodically commutates to realize the roll-in back and forth of steel pipe drawing portion between two roll shafts.
Further, described roll shaft is a camshaft structure.During practical operation, realize the roll-in back and forth of steel pipe drawing portion by the protruding end of camshaft.
Further, the groove depth of annular roller indent reduces to the other end step by step from an end of this roll shaft on the same roll shaft.Add man-hour, steel pipe drawing portion is from the feeding mouth of maximum, subtract the roll-in of wall, tube reducing successively backward, until satisfying technological requirement, this gradual processing mode has guaranteed that not only steel pipe pulls out the roll-in precision of head, and can avoid the time processing amount excessive and cause the appearance of situations such as device damage, the distortion of drawing portion.
Further, drive unit comprises support, motor and driving wheel group, and roll shaft is installed on the support by bearing, and motor is by the running of driving wheel group driven roller press mechanism.
Further, motor drives two roll shaft rotations simultaneously by driving wheel group.
Further, motor drives one of them roll shaft rotation by driving wheel group, and this roll shaft drives the rotation synchronous with it of another roll shaft by external wall friction.
The beneficial effects of the utility model: the utility model reasonable in design, simple operation, through the roll-in of two roll shaft repeated multiple times, the appearance and size of steel pipe drawing portion can satisfy the requirement of later stage drawing process, and can realize the processing of many specifications wall thickness product, has stronger practicality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the operation principle schematic diagram of the utility model embodiment one;
Fig. 3 is the operation principle schematic diagram of the utility model embodiment two.
The specific embodiment
As shown in Figure 1, the utility model seamless steel pipe drawing portion rolling device, the drive unit that comprises the roller press mechanism of forming by two roll shafts that are arranged side by side 1 and can drive this roller press mechanism running, it is axially arranged with some roads annular roller indent 11 roll shaft 1 upper edge, annular roller indent 11 on two roll shafts 1 is corresponding one by one to be formed the steel pipe drawing portion that 12, two roll shafts 1 of pass feeding mouth rotate in opposite directions to moving back and forth and carries out roll-in in feeding mouth; The groove depth of annular roller indent 11 reduces to the other end step by step from an end of this roll shaft 1 on the same roll shaft 1.Add man-hour, steel pipe drawing portion is from the feeding mouth of maximum, subtract the roll-in of wall, tube reducing successively backward, until satisfying technological requirement, this gradual processing mode has guaranteed that not only steel pipe pulls out the roll-in precision of head, and can avoid the time processing amount excessive and cause the appearance of situations such as device damage, the distortion of drawing portion; Drive unit comprises support 2, motor 3 and driving wheel group 4, and roll shaft 1 is installed on the support by bearing, and motor is by the running of driving wheel group driven roller press mechanism; Motor drives two roll shaft rotations simultaneously or drives one of them roll shaft rotation by driving wheel group, and this roll shaft drives the rotation synchronous with it of another roll shaft by external wall friction.
Embodiment one: as shown in Figure 2, in the present embodiment, roll shaft 1 adopts the cylinder axis structure.During practical operation, adopt the rotation mode that periodically commutates to realize the roll-in back and forth of steel pipe drawing portion between two roll shafts.When being the feeding of steel pipe drawing portion, the roll shaft of top turns clockwise, the roll shaft of below is rotated counterclockwise; When steel pipe drawing portion extracted, the roll shaft of top was rotated counterclockwise, the roll shaft of below turns clockwise; The cycle of direction of rotation conversion should will usually be determined according to the length of steel pipe drawing portion, the size of roll-in etc. are a plurality of.
Embodiment two: as shown in Figure 3, in the present embodiment, roll shaft 1 adopts camshaft structure, during practical operation, is realized the roll-in back and forth of steel pipe drawing portion by the protruding end of camshaft.Two roll shafts both can adopt the rotation mode that periodically commutates, and also can adopt the mode of unidirectional rotation, and the mode of unidirectional rotation as shown in Figure 3.
