Background technology
Pusher is on steel rolling production-line, steel billet to be advanced to the specific equipment heating in process furnace, often adopts mechanical type pusher on old-fashioned production line, and its volume is large. and price is high. and failure rate is high. and maintenance is complicated.Development along with steel rolling production, novel hydraulic pusher has progressively replaced old-fashioned mechanical pusher, and the advantage that thrust is large, volume is little, easy to operate that takes full advantage of hydraulic ram and baric systerm is simplified pusher operation greatly, equipment cost reduces greatly, is deeply subject to user's welcome.It is applied to respectively different pusher occasions, the effect that performance becomes more and more important in steel rolling is produced.
Pusher is applied to metallurgical Steel-rolling Industry, be generally used for and will on roller-way, push away roller-way to travelling car, in prior art, pass through the improvement to pusher push arm, pusher is had and push away steel and the dual function of drawing steel, can directly by retracting roller-way conveying, melt down, remove the convenience of rejecting with automobile from, but the realization upset of pawling of pusher needs manual work, increase operator's burden, easily caused dangerous accident; In addition, the push arm of process furnace location pusher, during use, working temperature is at 800 ℃--between 1000 ℃, under hot environment, life-time service easily goes out the end wear of push arm, the phenomenons such as push rod bending, the push arm of damage is very difficult when changing, and needs slitting saw excision, operation to whole production line produces serious influence, and has reduced production efficiency.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the invention provides the pusher that a kind of process furnace is pawled and overturn, rising and falling of this pusher gripper moves to carry out by drive unit, the temperature of the push arm of reduction pusher when work, prevent that it is crooked and damage, extending its life cycle.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
The pusher that process furnace is pawled and overturn, comprise and pawling and push arm, it is characterized in that: also comprise the drive unit of pawling, described push arm is divided into the arm head of front end and the armed lever of rear end, described push arm inside is provided with for passing into the circulation tube core of water coolant, described arm head is threaded with armed lever and fixes by pivot pin, and the sidewall of described push arm is respectively equipped with water outlet and water-in; The described drive unit of pawling is arranged on the platform of pawling, the described drive unit of pawling, comprise hydro-cylinder, drive cylinder, rotating push rod, runner, trave lling girder and slide plate, described slide plate is arranged on trave lling girder, described rotating push rod one end is connected with hydro-cylinder, the other end runner connects, and described driving cylinder is connected with runner by push rod.
The described drive unit of pawling also comprises track and pulley, and described track is fixed on pawls above, and described pulley is arranged on the bottom of trave lling girder and slides in orbit.
The present invention has the following advantages:
1, in the present invention, push arm is divided into the arm head of front end and the armed lever of rear end, described push arm inside is provided with for passing into the circulation tube core of water coolant, described arm head is threaded with armed lever and fixes by pivot pin, the sidewall of described push arm is respectively equipped with water outlet and water-in, as push arm, it is the visual plant in pusher, its inside is provided with circulation tube core, cooling water intake enters, at push arm internal recycle, thereby reduce the temperature of push arm, cooled water is discharged from water outlet, push arm temperature when operation can remain on below 300 ℃, effectively delayed the life cycle of push arm, push arm is threaded connection by the arm head of front end and the armed lever of rear end simultaneously, when arm head damages, can directly change, saved cost, improved production efficiency.
2, the drive unit of pawling described in the present invention is arranged on the platform of pawling, the described drive unit of pawling, comprise hydro-cylinder, drive cylinder, rotating push rod, runner, trave lling girder and slide plate, described slide plate is arranged on trave lling girder, described rotating push rod one end is connected with hydro-cylinder, and the other end runner connects, and described driving cylinder is connected with runner by push rod, rising and falling of pusher gripper moves to carry out by drive unit, realized automated operation.
3, the drive unit of pawling in the present invention also comprises track and pulley, and described track is fixed on pawls above, and described pulley is arranged on the bottom of trave lling girder and slides in orbit, completes lifting and the descending steady action of pawling, and has met the requirement of production technique.
