Embodiment Construction

[0045] The invention provides a forging production line for driven spiral bevel gear blanks of automobile rear axles. The production line uses ordinary crank presses to press blanks, vertical hole reamers to ream holes, twin-roll rolling machines to shape and automatic upper and lower feeding mechanisms to transfer blanks. The technical problems to be solved are: (1) Install two stations on each of the two crank presses to complete pre-forging blanks such as upsetting, punching, punching and skinning, and pre-shaping; (2) Automatic up and down feeding mechanism It can timely and accurately load, unload, and transfer blanks for the crank press and the double-roller rolling machine, and must be fully automatic; (3) The double-roller rolling machine is used to complete the shaping process of the forging.

[0046] In order to better understand the present invention, the present invention will be further described in conjunction with the accompanying drawings by taking "the production...

Abstract

The invention relates to an automotive rear axle driven bevel gear blank forging production line. The production line comprises the following equipment: preformed blank forming equipment, reaming production equipment and shaping production equipment, wherein the preformed blank forming equipment comprises two crank presses and two matched automatic feeding and discharging mechanisms so as to meet the production requirements of an upsetting step, a hole punching step, a wad punching step and a pre-shaping step, wherein the upsetting step and the hole punching step are carried out by one crank press and one matched automatic feeding and discharging mechanism; the reaming production equipment is a vertical reamer machine; and the shaping production equipment comprises a two-roller rolling machine with a shaping mould, and a matched automatic feeding and discharging mechanism, and the two-roller rolling machine shapes a reamed workpiece on the shaping mould to obtain an automotive rear axle driven bevel gear blank. The production line can effectively improve productivity, eliminates defects of forgings, and effectively saves raw materials by over 10 percent.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a production line for forging blanks of driven spiral bevel gears for automobile rear axles. Background technique [0002] The driven spiral bevel gear of the rear axle of the automobile is one of the key parts for the power transmission of the main gearbox of the rear axle of the automobile. See figure 1 , the forging 1 is a ring forging. At present, the main production line is: forging hammer pre-forging billet (upsetting→punching→punching→flattening), vertical reaming machine for final forming, this production line mainly has the following disadvantages: [0003] (1) Forging hammer pre-forging is impact forging, with high vibration and noise and poor working environment. [0004] (2) There are pits on the end face, large ellipticity (≥1mm), distortion and other defects in the final forming forgings of the vertical reaming machine. Therefore, the unilateral machining allowance of t...
