Description
Technical field
The present invention relates to steel manufacture field, delays 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 technology
Steel billet feeding buffer unit is that steel billet is carried out to stop the important of alignment effect before steel rolling mill's steel billet enters heating furnace
Equipment, steel billet need to be transported to heating furnace porch by charging roller mechanism before being rolled, then by pusher structure by steel
Base promote and heated in heating furnace (direction of charging roller mechanism transporting steel billet and the direction that steel billet moves in heating furnace into
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
It is required for steel billet feeding buffer unit to carry out stop alignment to steel billet during hot stove porch, steel billet is to feeding buffer unit per extremely big
Appointment is by the impact of 500 times or so.
The feeding buffer unit used at present is simple steelframe blocking mechanism.It can cause in use as follows not
Good influence：1st, energy-absorbing buffering effect of the simple steelframe blocking mechanism to steel billet impact process is smaller, causes steel billet to simple
Steelframe blocking mechanism impact is larger, and steelframe can cause to support simple steel using gross distortion can occur after some months
The foundation bolt of frame blocking mechanism loosens, and adds labor intensity to maintenance personal and adds maintenance maintenance equipment cost；
2nd, simple steelframe blocking mechanism to steel billet after stop alignment is carried out, and actual alignment effect is unsatisfactory so that pusher
When steel billet is pushed into heating furnace, steel billet often shows uneven situation, and occasional causes indivedual steel billet substantial deviations
The center line of heating furnace, it can cause to scratch the situation hair of heating furnace inwall when the steel billet of substantial deviation center line slides in heating furnace
It is raw, bring potential safety hazard to production.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, the purpose is achieved through the following technical solutions：
The present invention proposes a kind of steel billet feeding buffer unit, and the steel billet feeding buffer unit includes：
Drive member；

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
Buffer backstop and move component, the buffering backstop is moved component and is connected 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 in the case of motion with the buffering backstop to engage so that the resilient snubber is in the quiet component of the fixation and institute
State between buffering backstop moves component and be pressurized to form compression pretightning force.
It is advantageously improved according to one kind of the present invention, the dynamic component of buffering backstop is provided with can be quiet group with the fixation
Part engages so that the buffering backstop moves retainer of the component along the stretching direction stop motion.
It is advantageously improved according to another of the invention, the dynamic component of buffering backstop includes being used for and steel billet phase interaction
Buffer board and the sliding supporting part being slidably supported in the quiet component of the fixation, one end of the sliding supporting part is consolidated
Surely the buffer board is connected to, the other end of the sliding supporting part is connected to the drive member.
It is advantageously improved according to the another kind of the present invention, the resilient snubber is placed on the sliding supporting part, institute
State sliding supporting part and be provided with the buffering mating surface engaged with the abutting end of the resilient snubber so that when the buffering
Stopping element along the shrinkage direction move when, it is described buffering stopping element the buffering mating surface can be pressed against the bullet
Property bolster so that the resilient snubber the quiet component of the fixation and it is described buffering backstop move component between be pressurized with shape
Acted on into elastic buffer.
Preferably, the resilient snubber is compression spring.
Alternatively, the resilient snubber is high-temperature resistant ring-shaped rubber bodies.
It is advantageously improved according to another of the invention, the quiet component of fixation includes the base for being connected to foundation of civil work,
The fixed dam and sleeve being connected on the base, the fixed dam can be with the retainers of the dynamic component of the buffering
Engage so that the dynamic component of the buffering is used to accommodate the resilient snubber along the stretching direction stop motion, the sleeve.
According to a kind of preferred embodiment of the present invention, the drive member is connected to the bottom by support
Seat.
In addition, the present invention also proposes a kind of steel billet feeding system, the steel billet feeding system is included for transporting steel billet
Charging roller mechanism, for carrying out hot worked heating furnace to steel billet, steel is pushed away for steel billet to be pushed in the heating furnace
Mechanism, and steel billet feeding buffer unit as described above, the steel billet feeding buffer unit are used for passing through the feeding roller
The steel billet of road mechanism conveying forms cushioning effect, and is then delivered to appropriate position in alignment by 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, described
Steel billet feeding operating method comprises the following steps：
Drive the buffering backstop to move component by the drive member and move certain distance along the shrinkage direction, so as to
Apply certain compression pretightning force to the resilient snubber；
Driving steel billet feeding by the charging roller mechanism, described buffer after backstop moves component stops until steel billet hits
Motion；
Drive the buffering backstop to move component by the drive member to move until the buffering along the stretching direction
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.
It is 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, sliding supporting part is driven to shrink together by cylinder (suitable so as to apply to resilient snubber
When pretightning force), can greatly reduce impulsive force of the feeding steel billet to buffer unit when feeding steel billet impact attenuation device,
Additionally by the drive connection of cylinder and sliding supporting part, cylinder driving sliding supporting part stretches out together promotes buffer board reach to make
Obtain the regular alignment of steel billet and be located at appropriate position, solve the problems, such as that feeding steel billet is uneven again.
Therefore the invention has the advantages that：Excessively hitting to buffer unit when can thoroughly solve steel billet feeding
Hit, avoid buffer unit gross distortion and the injury to buffer unit foundation of civil work, so as to reduce equipment failure rate and reduction
The labor intensity and maintenance cost of maintenance personal, additionally, due to heating furnace is just pushed into after the regular alignment of steel billet, avoid steel billet
The uneven damage to heating furnace wall, eliminate the generation of work safety accident.
