通常,对具有两个轮缘的滚轮(如履带式车辆的履带支承导轮),是不可能将两个轮缘一次同时模锻出来的。传统的做法是:先锻出一个轮缘,再在平锻机上锻出其第二个轮缘:或者采取由两个锻件焊接拚成的方法。美国Presrite公司采用了一种“Rodonco Method”新方法,只需用简单的模具,在通用锻压机上就可以一次锻造具有两个轮缘的滚轮。据报道,该公司还将进一步用这一新方法,锻造具有四个轮缘的滚轮。此方法的诀窍在于模具的设计(原文附有照片)。当锻坯经过传统的方法预锻后,再由一副可分开的拚合环形模(split ring)夹住,一起放到终锻模内;此环形模与锻工操作的夹钳相连接,终锻模的上模和下模侧面有开口,以备夹
In general, it is not possible to swage both rims simultaneously with a wheel with two rims, such as a tracked guide wheel for a tracked vehicle. The traditional approach is to first forge a rim, then forge its second rim on a flat forging machine: or a method of welding from two forgings. Presrite, USA, has adopted a new “Rodonco Method” method that can forge a wheel with two rims on a universal forging press with a simple mold. It is reported that the company will further use this new method, forging a wheel with four rims. The trick to this method lies in the design of the mold (with photos attached). When the forging blank is pre-forged by conventional methods, it is held by a split split ring and placed in a final forging die. The ring die is connected to a forging operated clamp, Final forging die and die on the side of the opening, to prepare folder
