The utility model discloses a following technical scheme realizes, provides a backing plate for electroslag ingot upsetting, including the backing plate main part, be equipped with round platform shape standing groove at the upper surface of backing plate main part, the notch diameter of round platform shape standing groove is greater than the tank bottom diameter, is equipped with the circular through-hole of intercommunication backing plate main part lower surface in tank bottom department.
Preferably, the diameter of the groove bottom is 2.5 to 3 times the diameter of the feeding portion, and the diameter of the groove bottom is 250mm to 300 mm.
Preferably, the diameter Φ B of the circular through-hole is 1.5 to 2 times the diameter of the feeding portion, and the diameter range of the diameter Φ B of the circular through-hole is 150mm to 200 mm.
Preferably, a chamfer is arranged at the connecting part of the circular through hole and the groove bottom.
Preferably, the lower part of the circular through hole is blocked, and the height of the blocked part accounts for one fourth to one half of the height of the whole circular through hole.
Preferably, the lower blocking portion of the circular through hole is integrally constructed with the pad main body.
The utility model has the advantages that:
as an optimization improvement of the backing plate for upsetting the conventional electroslag ingot, the method ensures that the part with poor quality of the electroslag ingot is removed completely in the forging process, avoids the crack phenomenon of the electroslag ingot from extending, improves the utilization rate of the electroslag ingot and ensures the quality of a forged piece.

1. the base plate comprises a base plate main body, 2 circular truncated cone-shaped placing grooves, 3 notches, 4 groove bottoms, 5 circular through holes, 6 plugging portions, 7 chamfering edges, 8 feeding portions, 9 electroslag ingots, 10 upper pressing plates.
Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 4 and 5, the utility model discloses a backing plate main part 1 is equipped with round platform shape standing groove 2 at the upper surface of backing plate main part 1, and the 3 diameters of notch of round platform shape standing groove 2 are greater than tank bottom 4 diameters, are equipped with the circular through-hole 5 of intercommunication backing plate main part 1 lower surface in tank bottom 4 department.
In this example, the diameter of the groove bottom 4. PHI.A is 2.5 to 3 times the diameter of the feeding portion, and the diameter of the groove bottom 4. PHI.A ranges from 250mm to 300 mm. The diameter phi B of the circular through hole 5 is 1.5-2 times of the diameter of the feeding part, and the diameter range of the diameter phi B of the circular through hole 5 is 150mm-200 mm.
In the embodiment, in order to facilitate the feeding part 8 on the electroslag ingot 9 to be extruded into the circular through hole 5, a chamfer 7 is arranged at the connecting part of the circular through hole 5 and the groove bottom 4.
In this embodiment, in order to minimize the extrusion of the electroslag ingot at the non-feeding portion into the circular through hole 5, the lower portion of the circular through hole 5 is plugged, and the height of the plugging portion 6 occupies one quarter to one half of the height of the entire circular through hole 5. Further, the lower blocking portion 6 of the circular through hole 5 is integrally constructed with the pad main body 1.
When the upsetting device is used specifically, an electroslag ingot 9 needing upsetting is placed in the circular truncated cone-shaped placing groove 2 of the backing plate main body 1, a feeding portion 8 on the electroslag ingot 9 is opposite to the circular through hole 5, the electroslag ingot 9 is upset through the upper pressing plate 10, the feeding portion 8 is extruded into the circular through hole 5 in the upsetting process, the electroslag ingot is separated from the backing plate main body 1 after upsetting is finished, and the outward convex feeding portion is cut off. In the upsetting process, the upper pressure plate and the base plate main body 1 are matched with the hydraulic press for use, and the connection relationship among the upper pressure plate, the base plate main body 1 and the hydraulic press is the existing connection form, so that the details are not repeated.
