Abstract
The utility model discloses a dummy bar head capable of being replaced quickly. The dummy bar head capable of being replaced quickly comprises a dummy bar head front part and a dummy bar head rear part, wherein a T-shaped structure is arranged at the front end of the dummy bar head; a T-shaped groove is formed in the dummy bar head rear part; the T-shaped structure is placed in the T-shaped groove; the connecting position of the T-shaped structure and the T-shaped groove is subjected to electric welding, so that the dummy bar head front part is fixedly connected with the dummy bar head rear part. When the dummy bar head front part is burnt, a welded junction is blown and the dummy bar head front part is withdrawn and is replaced. The dummy bar head is divided into two parts which can be separated from each other, the T-shaped structure is arranged at the front end of the dummy bar head front part, and the T-shaped groove is formed in the dummy bar head rear part, so that the dummy bar head is replaced when the dummy bar head is burnt; therefore, the problems of high cost and replacement difficulty caused by replacing the overall dummy bar head are solved.
Description
Technical field
The utility model relates to dummy bar chain device, relates in particular to a kind of fast changeable dummy bar head.
Background technology
Although at present the dummy bar head in dummy bar chain is opened while watering and had the cold burden such as iron filings, spring between molten steel and dummy bar head at molten steel in the process using, inevitably molten steel is penetrated into dummy ingot head, causes dummy bar head scaling loss, need to again change dummy bar head.The weak point of this mechanism is 1, dummy bar head is changed continually, and a ton steel spare parts cost is high; 2, dummy bar head is changed difficulty.
How dummy bar head is improved, to make it be easy to change, thereby reduce equipment cost, convenient work is used, and has become the major issue of enhancing productivity.
Summary of the invention
The technical problem that the utility model is intended to solve is: thus a kind of dummy bar head that is easy to replacing, can reduces rolled steel dosage reduction equipment cost is provided.
For addressing the above problem, the technical solution of the utility model is: a kind of fast changeable dummy bar head, comprise dummy bar head, described dummy bar head comprises dummy bar head front portion and dummy bar head rear portion, the procephalic front end of described dummy ingot is provided with T-shaped structure, on dummy bar head rear portion, be provided with T-shaped groove, by T-shaped structure is positioned in T-shaped groove, realize dummy bar head anterior with being connected of dummy bar head rear portion.
Dummy bar head is anterior to be fixedly connected with by the mode of welding with dummy bar head rear portion.
Dummy bar head is anterior arranges large groove with the junction at dummy bar head rear portion.
1, dummy bar head is arranged to the two parts that can cut apart, only need change to it higher problem of cost while having avoided whole dummy bar head to change in the time of the anterior scaling loss of dummy bar head;
2, by T-shaped structure being set at the procephalic front end of dummy ingot, T-shaped groove is set on dummy bar head rear portion, has facilitated connection and the replacing at dummy bar head front portion and dummy bar head rear portion; ,
3, in dummy bar head front portion and the junction at dummy bar head rear portion large groove is set, facilitated both welding in connection procedure.
Accompanying drawing explanation
Fig. 1 is the structural representation of fast changeable dummy bar head described in the utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of dummy bar head front portion 1 in Fig. 1;
Fig. 4 is the structural representation at dummy bar head rear portion 2 in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model being done to one illustrates:
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4: a kind of fast changeable dummy bar head, described dummy bar head comprises dummy bar head anterior 1 and dummy bar head rear portion 2, the front end of described dummy bar head front portion 1 is provided with T-shaped structure 4; On dummy bar head rear portion 2, be provided with T-shaped groove 5.The T-shaped structure 4 of dummy bar head front portion 1 is positioned in T-shaped groove 5, thereby realizes being connected of dummy bar head anterior 1 and dummy bar head rear portion 2.By the mode of welding, both are fixed and are connected with the junction at dummy bar head rear portion 2 at dummy bar head anterior 1.
For convenience of welding, in dummy bar head anterior 1 and the junction at dummy bar head rear portion 2, large groove 6 is set.
When use, the T-shaped structure 4 of dummy bar head front portion 1 is positioned in T-shaped groove 5, and welds in junction, in the time of anterior 1 scaling loss of dummy bar head, weld is blown open, extract dummy bar head front portion 1 out and change.
By two parts of dummy bar head being arranged to can cut apart, when the anterior scaling loss of dummy bar head, only need change it, and the T-shaped structure arranging and T-shaped groove make to change more convenient easily, solved cost while replacing dummy bar head is whole high, change difficult problem.
Claims (3)
1. a fast changeable dummy bar head, comprise dummy bar head, it is characterized in that: dummy bar head comprises dummy bar head front portion and dummy bar head rear portion, the procephalic front end of described dummy ingot is provided with T-shaped structure, on dummy bar head rear portion, be provided with T-shaped groove, by T-shaped structure be positioned in T-shaped groove, realize dummy bar head anterior with being connected of dummy bar head rear portion.
2. fast changeable dummy bar head claimed in claim 1, is characterized in that: dummy bar head is anterior to be fixedly connected with by the mode of welding with dummy bar head rear portion.
