Abstract

The invention relates to a method for forging a step shaft with electroslag ingots. The method is suitable for forging the step shaft with large step diameter. A dead head end of an electroslag ingot is disposed on a upsetting drain cap for upsetting. The upset dead head end of the electroslag ingot forms a drum-shaped convex face and is elongated, due to the fact that the dead head end is the drum-shaped convex face, the dead head end is less prone to sinking, only a small part of dead head end needs to be cut off at last, pliers handle pressing with a hydraulic press in the original method is omitted, and the method has the advantages that the method is material-saving, utilization rate of forged piece is improved, and production cost is lowered.

Description

A kind of forging method of ESR ingot forging and stamping Step Shaft
Technical field
The present invention relates to a kind of forging method, be particularly useful for the forging method of a kind of ESR ingot forging and stamping Step Shaft of the large Step Shaft of stepped diameters.
Background technology
In the forging method of existing ESR ingot Step Shaft, as shown in Figure 1, ESR ingot is cooled by molten bath and forms rising head end 101 after ingot casting terminates, the concave surface that described rising head end 101 is formed for solution cooling meat, then forge, deepen along with forging ratio strengthens this concave surface, final formation shrinkage hole, as shown in Figure 2, in order to avoid not producing shrinkage hole, first utilize manipulator that the ESR ingot with rising head end is extruded pincers 102, in order to ensure forging ratio, as shown in Figure 3, then pincers are placed in the center of jumping-up drain cap 2 102, forging ratio is guaranteed after jumping-up being carried out to ESR ingot by hydraulic press, pull out finally by manipulator, because rising head end concave surface has been swaged into pincers handle, after final Step Shaft completion, pincers handle and rising head end all excise, but this way waste material, forging utilization rate is low, substantially increase production cost.
Summary of the invention
The applicant, for these shortcomings in above-mentioned existing production, provides another kind of ESR ingot to forge and press the forging method of Step Shaft, has saving material, improve the advantage of forging utilization rate and production cost.
The technical solution adopted in the present invention is as follows:
A forging method for ESR ingot forging and stamping Step Shaft, is characterized in that comprising the following steps:
The first step: ESR ingot is placed on jumping-up drain cap, described ESR ingot rising head end is downward;
Second step: utilize hydraulic press to ESR ingot jumping-up, forms cydariform after described ESR ingot rising head end jumping-up;
3rd step: utilize manipulator to be pulled out by ESR ingot described in step 2;
4th step: the rising head end that ESR ingot described in excision step 2 is formed.
Beneficial effect of the present invention is as follows:
The rising head end of ESR ingot is placed on jumping-up drain cap by the inventive method, then carries out jumping-up, forms cydariform convex surface, meet upset ratio after making the rising head end jumping-up of ESR ingot.Then pull out, now because rising head end is cydariform convex surface, not easily recessed contracting in pulling process, last only needs excises fraction rising head end, the method eliminates the step of original hydraulic press pressing tongs handle simultaneously, time saving and energy saving, save material, substantially increase forging utilization rate and enterprise's production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing ESR ingot.
Fig. 2 is by the schematic diagram of ESR ingot pressing tongs handle in existing method.
Fig. 3 is by the schematic diagram of ESR ingot jumping-up in existing method.
Fig. 4 is the schematic diagram be placed in by ESR ingot in the inventive method on jumping-up drain cap.
Fig. 5 be by ESR ingot jumping-up after structural representation.
Fig. 6 is the structural representation after ESR ingot pulling.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
The inventive method comprises the following steps:
The first step: as shown in Figure 4, is placed in the ESR ingot 1 with rising head end 101 on jumping-up drain cap 2.
Second step: utilize hydraulic press to carry out jumping-up to ESR ingot 1, because jumping-up drain cap 2 is provided with inner concave, ESR ingot 1 by after hydraulic press jumping-up, make ESR ingot 1 rising head end 101 jumping-up after form cydariform convex surface, cydariform convex surface is as shown in Figure 5.
3rd step: utilize the jaw of manipulator to clamp ESR ingot described in step 2, pull out described ESR ingot, because ESR ingot rising head end is cydariform end face, can not produce recessed contracting in pulling process.
4th step: finally excise rising head end.
By adopting the inventive method, through facts have proved, often prop up the material that ESR ingot can save a pincers handle.ESR ingot diameter conventional on 6000 tons of hydraulic presses is generally φ 1050 and φ 1300, often props up and saves pincers 1.5 ~ 2.5 tons.
The rising head end of ESR ingot is placed on jumping-up drain cap by the inventive method, then jumping-up is carried out, form cydariform convex surface after making the rising head end jumping-up of ESR ingot, then pull out, now because rising head end is cydariform convex surface, not easily recessed contracting in pulling process, last only needs excises fraction rising head end, and the method eliminates the step of original hydraulic press pressing tongs handle simultaneously, time saving and energy saving, save material, substantially increase forging utilization rate and enterprise's production cost.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to basic structure of the present invention, the present invention can do any type of amendment.
