The invention utilizes a mode of model precision forging, forges blanks of the cycloidal gear forging, and forges afterheat hardening and high-temperature tempering to replace the cycloidal gear of the speed reducer forged by air hammer moulding bed and common spheroids annealing, thereby improving product quality and production efficiency; moreover, the production costs of the cycloidal gear of the afterheat hardening is 800 to 1500 yuan/ton lower than that of the current process.
Description
Technical field
The present invention relates to a kind of production technology of cycloidal gear of speed reducer.
Background technology
At present, produce cycloidal gear of speed reducer and forge with the pneumatic hammer loose tool, its production technology is as follows: (the finished product master looks and looks schematic diagram with a left side and see Fig. 1, Fig. 2; The forging master looks and looks schematic diagram with a left side and see Fig. 3, Fig. 4)
A, purchase bearing steel (as GCr15) raw material;
B, blanking;
The bearing steel of c, blanking is heated to 1100～1150 ℃;
The blank of d, heating is put on the air hammer anvil loose tool swaged forging and makes, and finishes Cycloidal Wheel forging that the loose tool swaged forging makes directly in the pneumatic hammer punching, is swaged into the blanking of a Cycloidal Wheel forging and a punching; Behind the blanking cool to room temperature of punching, reheat, the loose tool swaged forging causes the Cycloidal Wheel forging blank of another part ting model again;
F, the Cycloidal Wheel forging cool to room temperature in air that is swaged into;
G, Cycloidal Wheel forging spheroidizing;
H, lathe roughing;
I. heat treatment;
J, lathe fine finishining;
K, finished product;
Above-mentioned technology has the following disadvantages:
1, large batch of product (product of same specification, a year more than tens ten thousand),, product quality big with labor intensity of operating staff entirely with artificial control, labour-intensive technology---the loose tool swaged forging is made.Large batch of Cycloidal Wheel forging products is inappropriate with the production of loose tool swaged forging fabrication technique.Use this technology, everyone per tour production Cycloidal Wheel forging blank 260-400 kilogram.Production efficiency is too low.
Factors such as 2, the product size tolerance range is big, endoporus is big with excircle eccentricity, the forging fillet is big cause the Cycloidal Wheel forging blank many with raw material.For example No. 6 Cycloidal Wheel forging blanks weigh 23.4 ~ 24 kilograms; No. 2 the Cycloidal Wheel forging blank weighs 2.5 ~ 2.8 kilograms.
3, the loose tool swaged forging on pneumatic hammer of Cycloidal Wheel forging is made for a long time, sweep away the endoporus gross weight that comes and can not continue to forge into another little Cycloidal Wheel forging, after can only reheating again the loose tool swaged forging make, waste energy, increase fire consumption, increase labor strength.
4, after the Cycloidal Wheel forging process for fuel is finished, behind the cool to room temperature, reheat 780-810 ℃, 3-6 hour spheroidizing of insulation again in the air, wasted the energy, take annealing device for a long time, production efficiency is low.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of and reduce production costs, enhance productivity and the Cycloidal Wheel production technology of quality.
For achieving the above object, the present invention adopts following technical proposals:
A kind of production technology of cycloidal gear of speed reducer may further comprise the steps:
A, purchase bearing steel (as GCr15) raw material;
B, blanking;
The raw material of c, blanking are heated to 1050～1150 ℃;
D, with step c heated raw materials base on pneumatic hammer;
E, with the steps d blank in the accurate closed die forging of forging equipment, finish forge goes out tooth, hole and the step of Cycloidal Wheel;
F, Cycloidal Wheel forging are cut overlap, punching the wad, shaping;
G, in boiling water, quench;
H, high tempering;
I. lathe roughing (processing capacity seldom);
J, heat treatment;
K, lathe fine finishining;
L, finished product.
Forging equipment among the described step e is: friction press, hotdie forging press.
The overlap equipment of cutting among the described step f is: punch press, friction press, oil pressure bead cutter.
Step a among the present invention, b, c, d, g, i, j, k, l are common process, do not repeat them here.
The present invention utilizes the accurate closed die forging of forging equipment, and finish forge goes out tooth, hole and the step of Cycloidal Wheel forging: utilize forging equipment to cut overlap, punching the wad, shaping, reduced and produced the raw material that the cycloidal gear of speed reducer forging is used.Replace traditional old-fashioned technology with above invented technology: the product quality that has improved the cycloidal gear of speed reducer forging; Improved production efficiency; Alleviated labor strength; Reduced production cost.After adopting the present invention, cycloidal gear of speed reducer production cost per ton is than 800～1500 yuan at existing technology joint.The annual cycloidal gear of speed reducer of producing in the whole nation can be saved social resources more than 1,700 ten thousand yuan more than 1.6 ten thousand tons.
