Abstract
The utility model discloses a combined-type thrust and stop linkage mechanism which comprises a fixed frame, a movable frame, a trolley and a pair of rollers. A rod core is mounted at the front end of the trolley, and the rollers, the movable frame and the fixed frame are sequentially mounted on a machine fame from front to back. A pair of thrust hydraulic cylinders are mounted on two side of the movable frame and used for fixing the movable frame, the trolley is arranged between the fixed frame and the movable frame and driven to move in a reciprocating mode by a driving motor and a driving chain, and a locking hydraulic cylinder is arranged between the trolley and the movable frame. A driving hydraulic cylinder is arranged between the fixed frame and the movable frame and used for driving the movable frame to move in a linear mode. The combined-type thrust and stop linkage mechanism is arranged on a rear table of a rolling mill in a multi-functional piercing and rolling mill, a stressed mode of a core rod is changed from tension to compression, and due to the combined type thrust and stop linkage mechanism, the effects that the position of ejector rod can be adjusted in a piercing process, and the stop route, the starting point and the ending point of the core rod can be adjusted in a rolling process are achieved.
Description
Technical field
The utility model relates to the slitless tube mill equipment technical field, specifically a kind of combined type thrust and restraint link gear.
Background technology
In piercing mill of seamless steel tube, ejector rob trolley provided thrust brake is at perforator background, and in traditional pipe mill, the mandrel movement limiting device is the foreground at pipe mill.Need two procedures just can finish the action of perforation and tube rolling.That is to say, in traditional punch and pipe mill, thrust is two kinds different mechanisms with restraint, does not have the action effect of interlock.
The utility model content
The purpose of this utility model is to provide a kind of combined type thrust and restraint link gear, and thrust and restraint function are integrated into one, mainly is applicable to universal mill.
The technical scheme in the invention for solving the technical problem is: a kind of combined type thrust and restraint link gear, it is characterized in that, comprise fixed mount, moving frame, dolly and a pair roller, front end mounting bar core at dolly, described roll, moving frame and fixed mount are installed on the frame from front to back in turn, and a pair of thrust hydraulic cylinder that moving frame is fixed is installed in the both sides of described moving frame; Described dolly is arranged between fixed mount and the moving frame, and a drive motors and driving-chain drive dolly and move back and forth, and are provided with locked hydraulic cylinder between dolly and moving frame, is provided with to drive the straight-line driving hydraulic cylinder of moving frame between described moving frame and fixed mount.
The beneficial effects of the utility model are: because omnipotent roll piercing mill combines the common feature of perforation and pipe mill, length lengthens to adapt to the needs of hollow billet length, so need the utility model to go to finish thrust and restraint action.In multi-functional roll piercing mill the utility model is located at the milling train backstage, the force way of plug becomes pressurized by tension.Adopt simultaneously combined type thrust and restraint link gear, the push rod position is adjustable when realizing perforation, and mandrel movement limiting stroke and initial sum terminating point are adjustable during tube rolling.
Description of drawings
Fig. 1 is principle schematic of the present utility model;
Fig. 2 is pierced billet process schematic diagram;
Fig. 3 is that dolly retreats schematic diagram;
Among the figure: 1 fixed mount, 11 drive hydraulic cylinders, 2 moving frames, 21 thrust hydraulic cylinders, 22 locked hydraulic cylinders, 3 dollies, 31 rod cores, 4 rolls, 5 steel pipes, 6 drive motors, the A operating point of boring a hole, the rolling operating point of B.
The specific embodiment
Such as Fig. 1～shown in Figure 3,
A kind of combined type thrust and restraint link gear comprise fixed mount 1, moving frame 2, dolly 3 and a pair roller 4, at the front end mounting bar core 31 of dolly 3.Roll, moving frame and fixed mount are installed on frame or the ground from front to back in turn.Fixed mount 1 is installed on the ground, and moving frame 2 is installed between roll and the fixed mount, and moving frame can before and after reciprocal traveling priority, between moving frame and fixed mount, be provided with and drive hydraulic cylinder 11, can drive moving frame integral body and move forward and backward.A pair of thrust hydraulic cylinder 21 is installed in the both sides of moving frame 2, is used for moving frame 2 is fixed, realize the function of thrust.Dolly 3 is between fixed mount and moving frame, and a drive motors 6 and driving-chain drive dolly and move back and forth, and simultaneously, are provided with locked hydraulic cylinder 22 between dolly and moving frame, so just can lock dolly.
The course of work is: the position of dolly to Fig. 1, and then drive hydraulic cylinder, thrust hydraulic cylinder, locked hydraulic cylinder and all lock, be in the thrust state, the beginning perforation process, this moment, punch position was positioned at the position, front side of roll, formed perforation operating point A; Then the thrust hydraulic cylinder unclamps, moving frame is at the uniform velocity mobile backward, along with the carrying out of perforation, drives the Driven by Hydraulic Cylinder moving frame mobile backward, and it is mobile backward to drive simultaneously dolly, the steel pipe 5 that so just can drive after the perforation is rolled, and rolling operating point B is between two rolls, in this course, rollingly be accompanied by perforation and carry out simultaneously, and rolling occurring in after the perforation, it is closer that both cooperate, and is in the restraint state.After complete rolling the finishing of steel pipe, to realize withdrawing from fast by drive motors and the drive chain at dolly rear portion, excellent core after extracting out transfers out the steel pipe of finishing, and finishes the mutual aid system devised for poor peasants of wearing of a steel pipe and does.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
