Embodiment Construction
[0014] The hot forging and extrusion die of the cycloidal wheel, the main part of the cycloid reducer, includes the upper die pad E and the lower die pad A. The upper die pad E and the lower die pad A are connected by two guide rails G, and one end of the guide rail G is set on the guide rail. In the sleeve F, the lower surface of the upper mold pad E is fixedly connected with the upper mold K by screws, the center of the upper mold K is provided with an upper mold H, and the lower end of the upper mold H is provided with a lower mold push block B corresponding to the upper mold H, A movement space for forging (squeezing) the cycloid wheel forging billet L is formed between the upper die H and the lower die push block B. The center of the lower die push block B is covered with a mandrel D, the lower die push block B and the base There are two through holes at the lower end of M, and there is a push rod C in the through holes that can make the push block B of the lower mold push...

The invention relates to a hot forging and extrusion die for a main component cycloidal wheel of a cycloidal speed reducer, comprising an upper die cushion and a lower die cushion, wherein the upper die cushion and the lower die cushion are connected by a rail; one end of the rail is sleeved in a guide sleeve; the lower surface of the upper die cushion is fixedly connected with an upper die plate; an upper die is arranged in the center of the upper die plate; the shape of the outer curve of the upper die is arranged to be the same as the outer curve of the cycloidal wheel; a die sleeve is installed on the lower die cushion in a corresponding position at the lower end of the upper die; the shape of the inner curve of the die sleeve is arranged to be the same as the shape of the outer curve of the cycloidal wheel; a lower die push block is installed in the die sleeve; and the shape of the outer curve of the lower die push block is arranged to be the same as the shape of the outer curve of the cycloidal wheel. The invention has the beneficial effects that the inner bore and the outer curve of the cycloidal wheel are formed by forging (extruding) once by a die, thus saving the raw materials consumed, reducing the subsequent machining processes, raising the labor productivity, reducing the energy consumption and increasing the economic benefit.
Description
technical field [0001] The invention relates to a processing device for a main part of a cycloidal reducer, in particular to a processing mold for a cycloidal wheel, the main part of a cycloidal reducer. Background technique [0002] The main part of the traditional processing cycloidal reducer, the cycloidal wheel, is mainly to dig out a circular through hole in the center of a circular blank by forging, etc., and then cut the periphery into a curved shape by machining and other methods. . The processed shape is as figure 1 shown. This kind of processing procedure is very wasteful of materials, and the process is relatively complicated, and at the same time, it consumes a lot of energy. Production efficiency is very low. Contents of the invention [0003] Aiming at the shortcomings of the existing technology for processing the cycloidal wheel of the cycloidal reducer, the invention provides a cycloidal wheel hot forging and extrusion molding (outer curve) mold of the ...
