The utility model is characterized in that the movable short mandrel device is arranged at the exit end of the Mannesmann tube mill, wherein, the movable short mandrel device comprises a short mandrel, an eject pin which is in thread connection with the short mandrel, an eject pin wheelbarrow which is connected with the other end of the eject pin through a coupling and is able to move on a rail, and a moving mechanism for driving the eject pin wheelbarrow. The utility model has the advantages of simple structure and low equipment investment and production cost.
Description
Technical field
The utility model relates to the rolling of metal, particularly relates to a kind of moveable short-core bar device of graceful formula pipe mill.
Background technology
The Man pipe mill is used for the rolling of seamless tubular goods, adopts long core bar device usually.Before rolling long plug is penetrated it in hollow billet with wearing bar device, it is rolling that the tubing that will be installed with long plug from the arrival end of Man pipe mill is sent into the Man pipe mill together.The hollow billet that has a long plug through the Man pipe mill rolling after,, by the special bar device that takes off long plug is extracted out at the port of export of Man pipe mill, enter the long plug of cooling device cooling of special setting then, recycle with this.
The employed long plug of prior art is generally more than 10m, and the requirement of long plug is very strict, require under the condition of high temperature, and not only intensity height but also wear-resisting, and also surface requirements is smooth.Long plug also need be aligned and grinding after use after a while.So strict requirement causes production cost very high.For this reason, long plug must be made in special large-scale producer.Factory needs supporting core rod straightening machine and long plug grinding machine, even the factory that has also is provided with special plug workshop.Because the Man pipe mill of prior art adopts long mandrel rolling at arrival end, therefore, not only whole unit equipment complexity, and the manufacture difficulty of long plug is very big, the production cost height.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of moveable short-core bar device of Man pipe mill is provided, and it has advantages such as set structure is simple, and equipment investment and production cost are low.
The utility model is achieved through the following technical solutions its purpose:
A kind of moveable short-core bar device of Man pipe mill, be by short plug in the configuration of the port of export of Man pipe mill, the push rod that is threaded with short plug, with the other end of push rod with shaft coupling be connected, and face motion in orbit is ejector rob trolley provided, and drives the moveable short-core bar device that ejector rob trolley provided travel mechanism forms.
The travel mechanism that described driving is ejector rob trolley provided, be by a driven by motor reductor, and by two power transmission shafts that are arranged in parallel of sprocket wheel transmission simultaneously, two power transmission shafts are connected with two leading screws respectively, move forward and backward along slideway by lead screw transmission lock vehicle frame, the lock vehicle frame is connected with ejector rob trolley provided by pivoted arm.
Described lock vehicle frame is connected with ejector rob trolley provided by pivoted arm, is on the lock vehicle frame cylinder to be set to drive pivoted arm, and pivoted arm is opened, and locks vehicle frame and ejector rob trolley provided disengaging, and pivoted arm puts down, and the lock vehicle frame blocks ejector rob trolley provided, makes ejector rob trolley provided whole mobile with the lock vehicle frame.
Described motor is a buncher, and by electric machine speed regulation, the translational speed of feasible short plug is guaranteed that tubing contacts with short plug all the time, thereby can be finished the rolling of tubing less than the mill speed of tubing in the operation of rolling when rolling.
The utility model compared with prior art has the following advantages and remarkable result:
Because the utility model adopts and uses movably short-core bar device at Man pipe mill port of export place, makes the equipment of whole unit become simply,, make the manufacturing of plug, reparation become easy especially because the utility model changes long plug into short plug.Therefore, greatly reduce equipment investment and production cost.In addition, because plug is short plug, configurable chilled water unit and lubricating arrangement in short plug make in the operation of rolling, and be lubricated while cooling off, and can improve tube quality and plug life-span.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is a kind of structural representation (front view) of moveable short-core bar device of Man pipe mill;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of moveable short-core bar device of Man pipe mill, be by short plug 1 in the configuration of the port of export of Man pipe mill, the push rod 2 that is threaded with short plug, be connected with shaft coupling 3 with the other end of push rod and on track 6, move ejector rob trolley provided 4, and drive the moveable short-core bar device that ejector rob trolley provided 4 travel mechanism 5 forms.
The travel mechanism 5 of described driving ejector rob trolley provided 4, be to drive reductor 5-2 by a motor 5-1, and the power transmission shaft 5-4 that is arranged in parallel by sprocket wheel (also can be belt pulley or gear) 5-3 two of transmissions simultaneously, two power transmission shafts are connected with two leading screw 5-5 respectively, 5-6 moves forward and backward along slideway 5-9 by lead screw transmission lock vehicle frame, and lock vehicle frame 5-6 is connected with ejector rob trolley provided 4 by pivoted arm 5-7.
Described lock vehicle frame 5-6 is connected with ejector rob trolley provided 4 by pivoted arm 5-7, be on the lock vehicle frame, cylinder (also can be hydraulic cylinder) 5-8 to be set to drive pivoted arm 5-7, pivoted arm is opened, lock vehicle frame and ejector rob trolley provided disengaging, pivoted arm puts down, it is ejector rob trolley provided that the lock vehicle frame blocks (pinning), makes ejector rob trolley provided whole mobile with the lock vehicle frame.
Screw mandrel 5-5 also available hydraulic cylinder replaces, and locks vehicle frame by the flexible drive of hydraulic cylinder and moves forward and backward.
For guaranteeing the screw mandrel stability of transmission, screw mandrel 5-5 two ends are supported by bearing 5-10, and wherein an end adopts thrust bearing (cone bearing) to bear the roll-force in the operation of rolling.
The course of work:
