Abstract
The invention relates to the technical field of fuel loading and unloading devices, in particular to a forging method for an unloading and temporary storage device-end flange. The forging method for the end flange specifically comprises the following steps that a, an upsetting round cake with the small thickness and the diameter height ratio being larger than 2.5 or a steel ingot with the small thickness and the diameter height ratio being larger than 2.5 is sawn into blanks arranged parallel to an upper wide flat platen and a lower wide flat platen which are arranged on a pressing machine in the metal fiber direction; b, the flat platen makes contact with the blanks entirely and the blanks are drawn out, like upsetting operating, and the steel ingot is drawn out to 1360 mm from initial 390 mm; and c, the drawn out steel ingot is put into a furnace again and heated, after being taken out of the furnace, the steel ingot is upset to the size of a forge piece. The improved forging method is simple in process and small in heating number, the manufacturing cost is reduced, the center of the forge piece is prevented from being sunken, and the forge piece can be forged sufficiently and solidly.
Description
Technical field
The present invention relates to fuel handling device technical field, especially a kind of forging method of discharging apparatus for temporary storage-end flanges.
Background technology
Fuel handling system is one of HTGR core system of domestic independent research first, and wherein discharging apparatus for temporary storage-end flanges is vital part wherein.Because this diameter of work is large, thickness is thin, in order to make forging real, most forge plant generally takes the scheme forging of three jumping-up+secondary pullings, makes forging ratio be greater than 3, although this scheme can forging method success, but because forging process is many, fire is secondary many, cause manufacturing cost too high.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides the forging method of a kind of discharging apparatus for temporary storage-end flanges.
The technical solution adopted for the present invention to solve the technical problems is: a kind of forging method of discharging apparatus for temporary storage-end flanges, and its step is as follows:
A. thickness is less, blade diameter length ratio be greater than 2.5 jumping-up cake or steel ingot sawing material base parallel with the upper and lower wide flat anvil on press by metal machine direction;
B. flat anvil contacts with blank entirety and pulls out, as jumping-up operation, steel billet is long from the thick pulling of initial 390mm to 1360mm;
C. the steel billet after pulling is melted down heating, after coming out of the stove, jumping-up is to forging ' s block dimension.
The invention has the beneficial effects as follows, operation is simple, and fire is secondary few, reduces manufacturing cost, avoids the recessed heart of forging, make forging fully be forged reality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is forging schematic diagram of the present invention.
Fig. 2 is end flanges front view of the present invention.
Fig. 3 is end flanges side view of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of forging method of discharging apparatus for temporary storage-end flanges, concrete steps are as follows: a. is less by thickness, blade diameter length ratio be greater than 2.5 jumping-up cake or steel ingot sawing material base parallel with the upper and lower wide flat anvil on press by metal machine direction; B. flat anvil contacts with blank entirety and pulls out, as jumping-up operation, steel billet is long from the thick pulling of initial 390mm to 1360mm; C. the steel billet after pulling is melted down heating, after coming out of the stove, jumping-up is to forging ' s block dimension.
Flat anvil and blank entirety to contact when pulling out as operated in jumping-up, add deformation velocity and an anvil deflection of heavy forging pulling, jumping-up is exactly by after blank heating, material base axis is parallel with hammering block to be placed on lower flat anvil, then with blank diameter direction being flattened to requiring height, and then overturn 90 ° of repetition aforesaid operations, finally pull out to required form size.
Forging method operation after improvement is simple, and fire is secondary few, reduces manufacturing cost, avoids the recessed heart of forging, make forging fully be forged reality.
