The technical scheme that the utility model solves the problems of the technologies described above is as follows: one times of elbow pushing of a kind of heavy caliber equipment, comprise base, two clamping plates, induction heating equipment of medium frequency and plug, described two clamping plates symmetry is fixed on the base, induction heating equipment of medium frequency is fixed between the two clamping plates, and described plug is inner through induction heating equipment of medium frequency.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described plug comprises feeding area and reducing district, and described feeding area is a cylindrical structure, described reducing district is a camber structure, one end in described reducing district is connected with an end of feeding area, and the reducing district comprises reducing cross section, sizing cross section and port cross section, and described reducing district seamlessly transits.
Further, described reducing cross section is a disc structure, interface for feeding area and reducing district, described sizing cross section is an oval structure, angle between itself and the reducing cross section is 60 degree, described port cross section is the oval structure identical with the sizing cross sectional shape, and the angle between itself and described sizing cross section is 30 degree.
Further, the long ratio range with minor axis length of the major axis in port cross section, described reducing district is 1.1-1.2.
Further, the long ratio range with described feeding area cylindrical structure diameter of the major axis in port cross section, described reducing district is 1.4-1.5.
Further, described plug is that reconditioning forms after the stainless steel casting.
The beneficial effects of the utility model are: one times of elbow pushing of a kind of heavy caliber described in the utility model equipment is because the improvement of plug, heating with induction heating equipment of medium frequency, making one times of elbow of production is seamless integral structure, its bore and wall thickness are very uniform, reliable in quality, bearing capacity are strong, and can realize one-shot forming, this times of seamless elbow pushing production efficiency of equipment is high, production cost is low.
Description of drawings
Fig. 1 is the structure chart of a kind of one times of elbow pushing equipment described in the utility model;
Fig. 2 is the structure chart of a kind of one times of elbow pushing equipment plug described in the utility model.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, plug, 2, induction heating equipment of medium frequency, 3, clamping plate, 4, base, 1-1, feeding area, 1-2, reducing district, 1-2-1, reducing cross section, 1-2-2, sizing cross section, 1-2-3, port cross section.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Be the structure chart of one times of elbow pushing of a kind of heavy caliber described in the utility model equipment such as Fig. 1, as shown in the figure, this times of seamless elbow pushing equipment comprises plug 1, induction heating equipment of medium frequency 2, two clamping plates 3 and base 4, described two clamping plates 3 symmetries are fixed on the base 4, induction heating equipment of medium frequency 2 is fixed between the two clamping plates 3, and described plug 1 is inner through induction heating equipment of medium frequency.
Fig. 2 is the structure chart of one times of elbow pushing of a kind of heavy caliber described in the utility model equipment plug, as shown in the figure, described plug 1 forms for the rear reconditioning of stainless steel casting, comprise feeding area 1-1 and reducing district 1-2, described feeding area 1-1 is a cylindrical structure, and described reducing district 1-2 is a camber structure, and the end of described reducing district 1-2 is connected with the end of feeding area 1-1, reducing district 1-2 comprises reducing cross section 1-2-1, sizing cross section 1-2-2 and port cross section 1-2-3, and described reducing district 1-2 seamlessly transits.
Wherein, described reducing cross section 1-2-1 is a disc structure, interface for feeding area 1-1 and reducing district 1-2, described sizing cross section 1-2-2 is an oval structure, angle between itself and the reducing cross section 1-2-1 is 60 degree, described port cross section 1-2-3 is the oval structure identical with sizing cross section 1-2-2 shape, and the angle between itself and described sizing cross section 1-2-2 is 30 degree.
