Abstract
The utility model relates to an output shaft forged piece of a cycloidal pin wheel reducer, wherein the diameter at one end of the forged piece is larger than that of the other end thereof, the larger-diameter end is provided with three stepped cylindrical cavities which are concave inwards and are sequentially reduced in diameters, and the surface of the smaller-diameter end is of a plane. The output shaft forged piece is positioned in a downwards-concave mold and pressurized and extruded from the upper and the lower ends (short for bidirectional closed type forging), and the forged output shaft forged piece has small forging allowance (single-edge forging allowance is 1.0-1.3mm) and good coaxiality, facilitates numerically-controlled lathe machining, and can realize forging waste heat quenching. Compared with the output shaft produced by die forging of the original air forging hammer, the output shaft forged piece of the cycloidal pin wheel reducer saves steel, reduces the technical standard of operators, improves the production efficiency, lightens the labor intensity, and lowers the production cost.
Description
Technical field
The utility model relates to a kind of forging, especially a kind of cycloidal planetary gear speed reducer output shaft forging.
Background technique
Produce cycloidal planetary gear speed reducer output shaft forging (hereinafter to be referred as the output shaft forging) at present and see Fig. 1 with the forging of pneumatic hammer loose tool,
Forging the output shaft forging with the pneumatic hammer loose tool has the following disadvantages:
1, little because of the pneumatic hammer blow energy, it is not enough that forging is full of power, add the resistance of the very dark and step of output shaft die cavity, the bar portion of output shaft can not be full of the inner chamber of mould, forging bar portion still keeps the size and the defective of pneumatic hammer base, for avoiding occurring waste product, have to strengthen machining allowance (the monolateral machining allowance 5 ~ 8mm) that stays of output axle portion, increased material consumption and later machining cost, for example No. 1 cycloidal planetary gear speed reducer output shaft forge weight is 4.5 kilograms.27.8 ~ 28.6 kilograms of No. 4 cycloidal planetary gear speed reducer output shaft forge weight
2, " field sowthistle herb " appears in the output shaft club head of producing with the pneumatic hammer loose tooling forging, increased raw material consumption and later machining processes and processing cost.
3, because of machining allowance is big, the forging appearance is lack of standardization, adopts residual forging heat quenching process machining difficulty.
4, with artificial control, labor intensity of operating staff is big entirely for quality of product, and 500 kilograms of output shaft forging 200-are only forged in everyone per tour.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to use, cycloid wheel speed reducer output shaft forging of saving steel, improve production efficiency and product quality is provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of cycloidal planetary gear speed reducer output shaft forging, described forging one end diameter are greater than the other end, and the bigger end of diameter is provided with and falls in the stepped cylindrical cavity that three diameters dwindle successively, and the less end end face of diameter is the plane.
The utility model output shaft forging is in recessed mould, and from two ends afterburning extruding (hereinafter to be referred as two-way closed-die forging) simultaneously up and down, forging can fully be crowded with entire die.The output shaft forging machining allowance that forges is little, and (monolateral machining allowance 1.0 ~ 1.3mm), coaxality is good, is convenient to lathe in machining, can realize remnant forging thermal quenching.The utility model forges the output shaft of producing with original pneumatic hammer loose tool and compares: save steel; Reduce operator's technical level; Enhance productivity; Alleviate labor strength; Reduce production costs.After adopting the utility model, can forge 1600 kilograms of output shaft 1400-through testing everyone per tour, cycloidal planetary gear speed reducer output shaft cost of production per ton is saved 400～700 yuan than existing technology.
