Description
Technical field
The present invention relates to lifting equipment, the forging method of especially a kind of lifting equipment wheel forging.
Background technique
Currently, lifting equipment wheel mainly passes through casting and forming, but because generating the casting such as loose shrinkage cavity in casting process
Defect is made, while also because casting environmental pollution is larger, it is imperative to forge rehandling.
Using forging technology, forging non-trimming and the very close wheel shape of forging outer diameter are processed convenient for subsequent handling.Forging
When the once-forming forging spoke of part and wheel rim, load needed for forging forming is excessive, excessively high to forging equipment requirement, and increase is produced into
This.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of lifting equipment forging methods of wheel forging, reduce and set
Standby load, improves equipment life.
The technical solution used to solve the technical problems of the present invention is that:
A kind of lifting equipment forging method of wheel forging, includes the following steps:
1, blank heating
Blank heating is kept the temperature to initial forging temperature and at such a temperature, until blank internal and external temperature is consistent;
2, mold preheats
During blank heating, mold is preheated, 200 DEG C -300 DEG C of mold preheating temperature;
3, blank preparation is come out of the stove
After blank heating and mold preheat, blank preparation is come out of the stove;
4, blank carries out jumping-up descaling
Blank is placed on heading die after coming out of the stove, and is carried out jumping-up to blank, is removed surface scale;
5, jumping-up base carries out finish-forging
(1) jumping-up base is placed into the intracavitary preparation of finish-forging die type and starts finish-forging,
(2) finish-forging upper mold downlink starts to forge, and finish-forging upper mold uses Bit andits control, finish-forging after finish-forging upper mold reaches setting displacement
Upper mold backhaul is suppressed again along axial-rotation certain angle;
(3) step (2) are repeated several times, until metal fills full finish-forging die type chamber, forging terminates.
The present invention by adopting the above technical scheme, compared with prior art, beneficial effect is:
Using upper mold rotation partial plastic forming forging, after the every certain stroke of compacting of upper mold, backhaul rotates by a certain angle and suppresses again, at
Shape Forging improves equipment life, improves forging quality to reduce shaping load.
Further, prioritization scheme of the invention is:
Bit andits control is respectively adopted in rough forge upper mold in step 4 and the finish-forging upper mold in step 5.
The number of revolutions of finish-forging upper mold is five times in step 5, every time 30 degree of rotation.

Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Referring to Fig. 1, Fig. 2, a kind of lifting equipment forging method of wheel forging includes the following steps:
1, blank heating: blank 2 is heated in heating furnace, is heated to initial forging temperature and is kept the temperature at such a temperature, until blank 2
Internal and external temperature it is consistent;
2, mold preheats: in 2 heating process of blank, preheating to heading die, finish-forging die, 200 DEG C of mold preheating temperature-
300℃;
3, blank preparation is come out of the stove: after the heating of blank 2 and mold preheating, the preparation of blank 2 is come out of the stove;
4, blank carries out jumping-up descaling:
(1) blank 2 is placed into jumping-up lower die 3 (shown in Fig. 3) after coming out of the stove, and carries out jumping-up to blank 2;
(2) 1 downlink of jumping-up upper mold carries out jumping-up to blank 2 and removes surface scale, and jumping-up upper mold 1 uses Bit andits control, works as upsetting
Jumping-up process terminates (shown in Fig. 4) after thick upper mold 1 reaches setting displacement, and blank 2 forms jumping-up base 4;
5, jumping-up base carries out finish-forging:
1) after 4 descaling of jumping-up base, jumping-up base 4 is placed into the mold cavity of finish-forging lower die 6, prepares to start finish-forging (figure
5, shown in Fig. 6);
(2) 5 downlink of finish-forging upper mold starts to forge, and finish-forging upper mold 5 uses Bit andits control, after finish-forging upper mold 5 reaches setting displacement
5 backhaul of finish-forging upper mold, is suppressed again along axial-rotation certain angle;
(3) it repeating step (2) five times, finish-forging upper mold 5 is successively rotated (shown in Fig. 7) by the direction of ABCDEF, every time 30 degree of rotation,
Full finish-forging die type chamber is filled to metal, forging terminates (shown in Fig. 8).
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to change with equivalent structure made by description of the invention and accompanying drawing content, it is intended to be included within the scope of the present invention.
