Abstract
The invention discloses a spring steel cover dismounting device of a cold bed gear plate, which comprises a draw bar, wherein the external diameter of the draw bar is smaller than the inner diameter of the spring steel sleeve. One end of the draw bar is provided with a cutting ferrule, wherein the cutting ferrule is connected fixedly with the draw bar. The outer diameter of the cutting ferrule is bigger than the inner diameter of the spring steel sleeve but smaller than the outer diameter of the spring steel sleeve. The other end of the draw bar is connected with a nut in a threaded mode. The draw bar is sleeved with a collecting sleeve and an annular hydraulic cylinder. The collecting sleeve contacts with the annular hydraulic cylinder and the annular hydraulic cylinder is close to the nut. After a piston of the annular hydraulic cylinder is stretched out, the piston can lean against the nut. The inner diameter of the collecting sleeve is bigger than the outer diameter of the spring steel sleeve. The dismounting device has the advantages of being simple in structure, and convenient to use, and effectively improving the dismounting speed of the spring steel cover, guaranteeing safety in construction and effectively lowering production cost of companies by reusing due to the fact that the dismounted spring steel cover is not ruined.
Description
Technical field
The present invention relates to metallurgical Steel-rolling Industry, particularly a kind of device for the Spring steel shroud of cold bed rack-plate is dismantled.
Background technology
Cold bed is that a kind of metallurgical Steel-rolling Industry effectively carries out cooling work top to rolled products (screw-thread steel, garden steel, steel pipe etc.), its operation principle is that roll forming product is delivered into cold bed by roller-way, pulled out again the forms such as tooth by the tooth bar step-by-step movement and will be arranged in workpiece on cold bed and progressively shift to the cold bed top, thereby reach, workpiece is carried out cooling purpose.
In the upkeep operation that the cold bed rack-plate is changed, the Spring steel shroud that needs first rack-plate to be located use splits out from locating hole.According to traditional maintenance technique, need first steel bushing to be cut out a seam with gas cutting tool and make its lost its bounce, then with sledgehammer, it is got from locating hole.Adopt this maintenance technique time-consuming, the effort, operating efficiency is low, and it is many to have more potential safety hazard, is easy to make workmen's health to come to harm in work progress.This maintenance technique of employing is arranged again, can not reuse after Spring steel shroud is cut again, generally can only scrap, will cause significant wastage like this, enterprise also need with buying new Spring steel shroud, so also can increase the production cost of enterprise every year.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of simple in structurely, easy to use, can improve Spring steel shroud and split out speed and can make the reusable provision for disengagement of Spring steel shroud.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of dismounting device for spring steel bushing on rack plate of cooling bed, it comprises a pull bar, the external diameter of described pull bar is less than the internal diameter of Spring steel shroud, one end of described pull bar is provided with a cutting ferrule, described cutting ferrule is fixedly connected with described pull bar, the external diameter of described cutting ferrule is greater than the internal diameter of Spring steel shroud but less than the external diameter of Spring steel shroud, the other end of described pull bar is connected with a nut thread, on described pull bar, cover has one to collect cover and annular hydraulic cylinder, described collection cover contacts with described annular hydraulic cylinder, described annular hydraulic cylinder is near described nut, can be resisted against on described nut after the piston of described annular hydraulic cylinder stretches out, the internal diameter of described collection cover is greater than the external diameter of Spring steel shroud.
Preferably, described cutting ferrule is connected with described pull rod screw.
Preferably, described annular hydraulic cylinder is connected with hydraulic pump.
Technique scheme has following beneficial effect: this provision for disengagement in use, at first turn on nut, to collect cover and annular hydraulic cylinder unloads, make pull bar pass Spring steel shroud, and then load onto and collect cover and annular hydraulic cylinder, and fastening nut, then driving annular hydraulic cylinder makes the piston of annular hydraulic cylinder protruding, the piston of annular hydraulic cylinder withstands nut, and then drives cutting ferrule and withstand Spring steel shroud, and Spring steel shroud can eject from the cold bed rack-plate under the thrust of cutting ferrule like this.This provision for disengagement is simple in structure, easy to use, can effectively improve the dismounting speed of Spring steel shroud, and can guarantee construction safety, and therefore the Spring steel shroud that disassembles can also be reused due to without destruction, so also can effectively reduce the production cost of enterprise.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this dismounting device for spring steel bushing on rack plate of cooling bed comprises a pull bar 3, and the external diameter of pull bar 3 can be convenient to like this pull bar 3 and pass Spring steel shroud 2 less than the internal diameter of Spring steel shroud 2.One end of pull bar 3 is provided with a cutting ferrule 4, and cutting ferrule 4 is threaded with pull bar 3, and the external diameter of cutting ferrule 4 is greater than the internal diameter of Spring steel shroud 2 but less than the external diameter of Spring steel shroud 2, can be convenient to like this cutting ferrule 4 and withstand Spring steel shroud 2.The other end of pull bar 3 is threaded with a nut 8, also overlapping on pull bar 3 has one to collect cover 5 and annular hydraulic cylinder 6, collect cover 5 and annular hydraulic cylinder 6 side by side, collecting cover 5 contacts with annular hydraulic cylinder 6, annular hydraulic cylinder 6 is near nut 8, can be resisted against on nut 8 after the piston 7 of annular hydraulic cylinder 6 stretches out, annular hydraulic cylinder is connected with a hydraulic pump, and the internal diameter of collecting cover 5 should be greater than the external diameter of Spring steel shroud 2.
as shown in Figure 1, this provision for disengagement in use, at first turn on nut 8, make pull bar 3 pass Spring steel shroud 2 on cold bed rack-plate 1, and then load onto and collect cover 5 and annular hydraulic cylinder 6, and fastening nut 8, then make hydraulic pump works, driving annular hydraulic cylinder 6 makes its piston 7 protruding, the piston 7 of annular hydraulic cylinder just can withstand nut 8 like this, and then drive cutting ferrule 4 withstands Spring steel shroud 2, collect cover 5 and withstand a rack-plate 1, Spring steel shroud 2 can eject from cold bed rack-plate 1 under the thrust of cutting ferrule 4 like this, and fall in collection cover 5, use collection cover 5 can prevent that Spring steel shroud 2 from having foreign material to fall when ejecting, can guarantee construction safety.
This provision for disengagement is simple in structure, easy to use, can effectively improve the dismounting speed of Spring steel shroud, and can guarantee construction safety, and therefore the Spring steel shroud that disassembles can also be reused due to without destruction, so also can effectively reduce the production cost of enterprise.
Above a kind of dismounting device for spring steel bushing on rack plate of cooling bed that the embodiment of the present invention is provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
