Description
Technical field
The utility model relates to a kind of hot rolling does not have the punch equipment that meets in the pipe production line, specially refers to the top changing device more in this punch.
Background technology
Hot rolled seamless steel tube be by solid pipe wear long the hole machine rolling after, shut out hollow hollow billet, in the rolled by piercing mill process, the top is a kind of perishable tool, has certain life-span, when a normal rolling hollow billet number in top reach a certain amount of after, just must change, in addition, in when, because of technology or equipment reason rolling fault taking place when, also may cause the damage of top, also need to change the top.At present, the substitute mode that comes directly towards in the drilling/rolling process has two kinds: a kind of is to shut down manually to change when the top is damaged; Another kind is to be the higher situation of equipment complexity, automaticity of representative with the continuous rolling-tube unit, adopts the mode of changing the top automatically to carry out.Frequent replacing top in the operation of rolling generally is to change once top each rolling cycle, and when the top replacing was frequent, the loss of top reduced relatively, and can in time reject and damage the top, replenished new the top, had improved rolling operating rate.Quick-replaceable principle in the top of this equipment and structure are such: the top quick replacement device is between one section of punch outlet platform takes off two sections of pipe unit and punch outlet platforms, change casing by the top, hanging basket, erecting device, swing gate, erection device, compositions such as transfer device, its major function is and three hydraulic cylinder interoperations that export two sections mandril anti-thrust trolleys of platform, realize the fast online replacement of top, the hanging basket of placing the top has 2, each hanging basket has 3 top stations, but integral lifting goes out the top changes case, drive progressively handover in casing by transfer device, 5 steps of advancing in each cycle were returned for 5 steps and amounted to for 10 steps, reciprocation cycle, realize that a top withdraws from the change successively that this cyclic process is installed with next top, cooling is realized in the changing device coming directly towards more in the top of resigning from office.After last Zhi Maoguan shuts out, dolly drives the top and turns back to position after the work, three cylinder actions of dolly, separate with push rod the top, electric motor starting, drive hanging basket by link chain mechanism and move a step pitch, the hanging basket V-shaped groove that the top of just backing off being housed shifts out roll line and cools off in the changing device coming directly towards more, and another the hanging basket V-shaped groove that has cooled off good top that is equipped with that is adjacent simultaneously moves into roll line, the erection device action, make the top center line consistent with roll line, swing gate rises, and prevents the top reach, and three cylinders of dolly reset, the top combines with push rod, and dolly advances to the work anteposition and carries out the rolling of next cycle.But at the scene in the production process, above-mentioned automatically when more plug changer exists the top to dock with push rod, erection device usually takes place do not set upright the top, make come directly towards center line and the push rod center line inconsistent, cause top and push rod not to be in place, cause the rolling accident of not having the top perforation when serious.
Summary of the invention
The top quick replacement device that the utility model has solved in the automatic continuous rolling-tube unit will come directly towards when docking with push rod, the normal generation of erection device can not be set upright the top, make top center line and push rod center line inconsistent, thereby had influence on the technical problem of the quality of the hollow hollow billet that rolls out.
Because the profile of top is the cone as sub warhead, the wiper block that is the plane by a working face when changing docks with push rod after with its conical nose jack-up, at this time the taper top is easy to rock, total invention thinking of the present utility model is that the wiper block working face is provided with forming V-shape, thereby avoided rocking of top, it is accurately docked with push rod.
The utility model comprises pneumatic linear actuator 1, power transmission shaft 2, hanging basket 8, be used to place three V-shaped grooves that are rigidly connected of top, the centre bottom of each V-shaped groove is provided with passes through the hole, its below is provided with wiper block 7, this wiper block can be under the driving of pneumatic linear actuator 1 and power transmission shaft 2, pass the hole of the bottom of V-shaped groove and go to set upright the top that is placed on the V-shaped groove, the working face of described wiper block 10 is V-arrangement working faces.
Described top quick replacement device can be provided with the top clamping device, and he is by pneumatic linear actuator 1, and power transmission shaft 2 and top crimp lug 9 will be changed the top and clamp.
Another kind of implementation of the present utility model is: the top quick replacement device, comprise pneumatic linear actuator 1, power transmission shaft, 2, hanging basket 8, wiper block 7, be set with bearing block 3 on the described hanging basket 11, it is provided with axle sleeve 6 and bearing pin 4, described bearing block 3 flexibly connects by bearing pin 4 and single V-shaped groove, single V-shaped groove can be swung around gyroaxis separately respectively, the bottom of single V-shaped groove is set with a plane operation block, corresponding with wiper block 7, by setting upright the plane operation block of V-shaped groove bottom, jacking block axis and push rod axis on the V-shaped groove are aligned.
Described top quick replacement device can be provided with the top clamping device, and he is by pneumatic linear actuator 1, and power transmission shaft 2 and top crimp lug 9 will be changed the top and clamp.
The beneficial effects of the utility model are that the top quick replacement device in the automatic continuous rolling-tube unit reliably is in place when changing the top, have avoided owing to the rolling accident that causes not in place is installed.
