Abstract
The invention discloses a rotary core rod device for a core rod limiting type continuous tube mill, relating to steel rolling machinery and solving the problem that the traditional core rod limiting type continuous tube mill is difficult to remove a core rod. The rotary core rod device comprises a core rod limiting trolley and a supporting rod connected with the core rod limiting trolley through a flange, wherein the supporting rod is threaded with the core rod. The rotary core rod device is characterized in that a main shaft of the core rod limiting trolley is connected with an active rotating device through a flange, and a bearing is arranged between the main shaft and a housing of the core rod limiting trolley. The rotary core rod device is used for the core rod limiting type continuous tube mill, and solves the problem of core rod removal because the core rod is wrapped by a tubular material due to the rotation of the core rod; and meanwhile, the service life of the core rod is prolonged.
Description
Technical field
The present invention relates to rolling machinery, particularly retained mandrel formula tandem rolling tube machine.
Background technology
Tandem rolling tube machine rolling has dual mode: a kind of be plug in company with the pipe free floating, be called Tandem Tube Rolling Mill with Full Floating Mandrel (as accompanying drawing 1); Another kind is that plug speed can be controlled, and is called retained mandrel tandem rolling tube machine (as accompanying drawing 2).The tandem rolling tube machine of prior art, plug advances with linear fashion in the operation of rolling, and tubing also advances with linear fashion.
When rolling, plug and tubing are gone together or linear relative movement.When roll and plug were rolled tubing, the gap of plug and tubing was very little, and especially when rolling temperature reduced, tubing can encase plug, caused and can't take off rod.Therefore, be furnished with mandrel bar loosening mill, winding arbor extraction press after the full floating continuous rolling-tube unit specially, solve the excellent problem of taking off.Take off excellent difficult present situation though there is the tandem rolling tube machine of retained mandrel to improve, but because retained mandrel is short than floating core rod, the duty factor floating core rod of retained mandrel under the HTHP double action is serious, therefore, there is the tandem rolling tube machine of retained mandrel still often to take off excellent situation of difficult, the necessary plug of often changing in the production.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of rotation core bar device that is used for retained mandrel formula tandem rolling tube machine is provided, solve the problem that existing retained mandrel tandem rolling tube machine takes off the rod difficulty.
The present invention is achieved through the following technical solutions:
A kind of rotation core bar device that is used for retained mandrel formula tandem rolling tube machine, comprise: plug restraint dolly, the support stick that connects by flange with plug restraint dolly, support stick and plug thread connection, it is characterized in that: the main shaft of described plug restraint dolly connects by flange with the active rotation device, between the housing of described main shaft and described plug restraint dolly bearing is housed.
Described active rotation device is a kind of hydraulic motor, or motor-belt, motor-chain gear transmission, or the cycloid speed reducer transmission of the transmission of servomotor direct connection, translator etc.
The present invention compared with prior art because the main shaft of plug restraint dolly connects with active rotation device 1, makes plug rotate in the operation of rolling, and having solved plug can be taken off excellent problem by what tubing encased.Simultaneously, because the rotation of plug, the mandrel rolling line length that effectively extended has reduced the thermic load on the unit are, has prolonged the service life of plug.
Description of drawings
Fig. 1 is the Tandem Tube Rolling Mill with Full Floating Mandrel operation principle schematic diagram of prior art;
Fig. 2 has a retained mandrel tandem rolling tube machine operation principle schematic diagram for prior art;
Fig. 3 is a structural representation of the present invention.
The present invention is described further by most preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 3, a kind of rotation core bar device that is used for retained mandrel formula tandem rolling tube machine comprises: plug restraint dolly 2, the support stick 5 that connects by flange with plug restraint dolly 2, support stick 5 and plug 6 thread connection; The main shaft 2-1 of described plug restraint dolly 2 and active rotation device 1 connect by flange, between the housing of described main shaft 2-1 and described plug restraint dolly 2 bearing 2-2 are housed.
Described active rotation device 1 is a kind of hydraulic motor, or motor-belt, motor-chain gear transmission, or the transmission of servomotor direct connection etc.
The course of work of the present invention:
The wheel 4 of plug restraint dolly 2 is in the constraint lower edge of restraint oil cylinder guide rail 3 operation, and under the rotation of roll 7, tubing 8 enters rolling section and carries out vertically rollingly, and plug 6 moves forward or backward according to technological requirement.
When active rotation device 1 rotation, the main shaft by plug restraint dolly 2 drives support stick 5 and plug 6 rotate simultaneously, and after support stick 5 and plug 6 penetrated tubing 8, plug restraint dolly 2 was in axial feed, and support stick 5 and plug 6 produce and rotate.The rotation of plug in the operation of rolling, not only solved plug 5 and can have been taken off excellent problem by what tubing 8 encased, and because the rotation of plug, roll line is changed into helical trajectory by original straight path, the mandrel rolling line length has effectively extended, thereby reduced the thermic load on the unit are, prolonged the service life of plug.
