Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] see figure 1 , The embodiment of the present invention provides a bevel gear forming device, the device includes a rotary rolling machine and a mold, and the mold is arranged on the rotary rolling machine. Among them, the mold is used to shape the ring material (after the hole expansion process). Wherein, mold comprises upper mold 51, lower mold 52 and die cushion 53 that are arranged successively from top to bottom, lower mold 52 is fixed, and upper mold 51 can be driven by swing rolling machine to carry out swing rolling motion, and upper mold 51 and lower mold 52 are opposite to each other. set up. The bottom of lower mold 52 is provided with mold cushion 53, and the mold cavity that upper mold 51, lower mold 52 and mold cushion 53 form is consistent w...

Abstract

The invention discloses a bevel gear forming device and belongs to the technical field of automobile part production. The bevel gear forming device comprises a rotary forging press and a mould arranged on the rotary forging press. The mould comprises an upper mould body (51), a lower mould body (52) and a mould cushion (53), wherein the upper mould body (51) and the lower mould body (52) are arranged oppositely; the mould cushion (53) is arranged at the bottom of the lower mould body (52); a mould cavity formed by the upper mould body (51), the lower mould body (52) and the mould cushion (53) is consistent with a product in shape; the mould cushion (53) is of an annular structure; an ejector rod of the rotary forging press is arranged inside the mould cushion (53). The bevel gear forming device has the advantages of being high in degree of automation, good in product quality, low in rejection rate, good in working environment and the like.

Description

technical field [0001] The invention belongs to the technical field of auto parts production, in particular to a bevel gear forming device. Background technique [0002] In the past, the final forging and pressing of the basin angle teeth of the drive axle reducer assembly of medium and heavy vehicles was forged with a hole reaming machine or a large-tonnage friction press. This final forging processing method has a large blank machining allowance, many blank surface defects, creases, and eccentricity are not easy to control; the blank scrap rate is high, the quality of the team is high, and the equipment is expensive, tall, and the mold module is also large and easy to damage; general Forging manufacturers dare not easily get involved in the forging of this product. Contents of the invention [0003] With the development of the equipment manufacturing industry, a new type of forging equipment called a swing forging machine has appeared on the market. After repeated demo...
