Description

Steel billet feeding buffer unit, steel billet feeding system and its operating method
Technical field
The present invention relates to steel manufacture fields, slow more particularly to a kind of steel billet feeding buffer unit including the steel billet feeding The steel billet feeding system and its operating method of flushing device.
Background technique
Steel billet feeding buffer unit is to carry out stopping the important of alignment effect to steel billet before steel rolling mill's steel billet enters heating furnace Equipment, steel billet need to be transported to before being rolled heating furnace inlet by charging roller mechanism, then by pusher structure by steel Base promote and heated in heating furnace (direction that the direction of charging roller mechanism transporting steel billet and steel billet move in heating furnace at 90°).Charging roller mechanism transports three steel billets every time, and at 3 tons or so, each steel billet is transported to be added the weight of every steel billet Steel billet feeding buffer unit being required when hot stove inlet, blocking alignment being carried out to steel billet, steel billet is to feeding buffer unit per extremely big It about will receive 500 times or so impacts.
Feeding buffer unit used at present is simple steelframe blocking mechanism.It will cause in use as follows not Good influence: 1, simple steelframe blocking mechanism is smaller to the energy-absorbing buffering effect of steel billet impact process, causes steel billet to simple Steelframe blocking mechanism impact force is larger, and steelframe is severely deformed using that can occur after some months, while will cause the simple steel of support The foundation bolt of frame blocking mechanism loosens, and increases labor intensity to maintenance personal and increases maintenance maintenance equipment cost; 2, for simple steelframe blocking mechanism after carrying out blocking alignment to steel billet, actual alignment effect is unsatisfactory, so that pusher When steel billet is pushed into heating furnace, steel billet often shows irregular situation, will cause individual steel billet substantial deviations once in a while The steel billet of the middle line of heating furnace, substantial deviation middle line will cause the case where scratching heating furnace inner wall hair when sliding in heating furnace It is raw, security risk is brought to production.
Summary of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, which is achieved through the following technical solutions:
The present invention proposes that a kind of steel billet feeding buffer unit, the steel billet feeding buffer unit include:
Drive member;
It is fixedly attached to the quiet component of fixation of foundation of civil work;
Resilient snubber, the resilient snubber have be fixedly attached to the quiet component of the fixation fixing end and with it is described The opposite abutting end of fixing end;With
It buffers backstop and moves component, the buffering backstop is moved component and connect with the drive member, and can be by described The driving effect of drive member moves back and forth along shrinkage direction and stretching direction;
Wherein, the abutting end of the resilient snubber can move component along the shrinkage direction in the buffering backstop Component is moved with the buffering backstop in the case where movement to engage to make the resilient snubber in the quiet component of the fixation and institute It states and is pressurized between the dynamic component of buffering backstop to form compression pretightning force.
One kind according to the present invention is advantageously improved, and the dynamic component of the buffering backstop is provided with can be quiet group with the fixation Part engagement is to make the buffering backstop move component along the retainer for stretching out direction stop motion.
It is according to the present invention another be advantageously improved, the buffering backstop move component include for steel billet phase interaction One end of buffer board and the sliding supporting part being slidably supported in the quiet component of the fixation, the sliding supporting part is solid Surely it is connected to the buffer board, the other end of the sliding supporting part is connected to the drive member.
Another kind according to the present invention is advantageously improved, and the resilient snubber is placed on the sliding supporting part, institute It states sliding supporting part and is provided with the buffering mating surface engaged with the abutting end of the resilient snubber, so that working as the buffering When stopping element is moved along the shrinkage direction, the buffering mating surface of the buffering stopping element can be pressed against the bullet Property bolster to make the resilient snubber move between component compression in the quiet component of the fixation and the buffering backstop with shape It is acted at elastic buffer.
Preferably, the resilient snubber is compressed spring.
Alternatively, the resilient snubber is high-temperature resistant ring-shaped rubber bodies.
It is according to the present invention another be advantageously improved, the quiet component of fixation includes the pedestal for being connected to foundation of civil work, The fixed baffle and sleeve being connected on the pedestal, the fixed baffle can be with the retainers for buffering dynamic component It engages so that described buffer dynamic component along the stretching direction stop motion, the sleeve is for accommodating the resilient snubber.
According to a preferred embodiment of the present invention, the drive member is connected to the bottom by bracket Seat.
In addition, the present invention also proposes a kind of steel billet feeding system, the steel billet feeding system includes for transporting steel billet Charging roller mechanism pushes away steel for pushing to steel billet in the heating furnace for carrying out hot worked heating furnace to steel billet Mechanism and steel billet feeding buffer unit as described above, the steel billet feeding buffer unit are used for by the feeding roller The steel billet of road mechanism conveying forms buffer function, and is then delivered to position appropriate in alignment for steel billet is regular.
Finally, the present invention also proposes a kind of steel billet feeding operating method implemented by above-mentioned steel billet feeding system, it is described Steel billet feeding operating method the following steps are included:
It drives the buffering backstop to move component by the drive member and moves certain distance along the shrinkage direction, thus Apply certain compression pretightning force to the resilient snubber;
Steel billet feeding is driven to stop until steel billet is hit after the buffering backstop moves component by the charging roller mechanism Movement;
It drives the buffering backstop to move component by the drive member to move along the stretching direction until the buffering The retainer that backstop moves component engages the quiet component of fixation;
Steel billet is pushed into the heating furnace by the pusher structure to be heated.
As described above, slow by installing sliding supporting part, such as sliding support and an appropriate number of elasticity in buffer unit Stamping, such as cylindroid helical-coil compression spring drive sliding supporting part to be shunk together (to apply to resilient snubber suitable by cylinder When pretightning force), feeding steel billet can be greatly reduced when feeding steel billet impact attenuation device to the impact force of buffer unit, Additionally by the drive connection of cylinder and sliding supporting part, cylinder driving sliding supporting part stretches out together pushes buffer board Forward to make It obtains the regular alignment of steel billet and is located at position appropriate, and solve the problems, such as that feeding steel billet is irregular.
Therefore the invention has the following advantages: being hit when can thoroughly solve steel billet feeding to the excessive of buffer unit It hits, avoids buffer unit severely deformed and the injury to buffer unit foundation of civil work, to reduce equipment failure rate and reduction The labor intensity and maintenance cost of maintenance personal avoids steel billet additionally, due to heating furnace is just pushed into after the regular alignment of steel billet The irregular damage to heating furnace wall, eliminates the generation of work safety accident.
