Wherein, the concentricity of the whole structure mainly depends on the mechanical precision of the external mold, the inner hole of the ingot container, the plug and the internal mold and on the extrusion central axis as the best. Therefore, the yield and concentricity of the fine equipment at the initial stage of use can meet the standard. However, in use, the concentricity of the apparatus may change due to mechanical wear and deformation of the piercing pin, which reduces the yield.

However, the concentricity adjustment method in this case can only correct the misalignment by rotating the pin, adjusting the center of the pot, or changing the axis. The method comprises the following specific steps: (1) The inner mould is fixed on the perforating needle, namely the last fixed body of the inner mould is a perforating oil cylinder and a main plunger, and the abrasion of the last fixed body can cause the movement track of the inner mould to form an included angle with the central line so as to generate deviation; (2) The center or the axis direction of the ingot containing barrel is adjusted mainly by adjusting screws at the front, the back, the left, the right, the upper end and the lower end of the ingot containing barrel, so that the inner hole coincides with the axis of the perforating needle, the adjustment is time-consuming and labor-consuming, the concentricity can be realized only by forming an included angle with an extrusion center line, and the adjusted screws can be deformed or loosened again by strong extrusion force.

Therefore, the adjustment method often causes that the deviation of the front, middle and rear sections of the adjusted product is not as expected, and after the adjustment is finished, a plurality of ingots may be changed again, so that the adjustment time is long, the labor intensity is high, and the reliability is not high.
