The utility model relates to a die for forging a fork head of a connecting head, which has a punch and a concave die. The diameter of the upper part of the punch is the same as the inner diameter of the fork head of the connecting head, and the shape of the lower part is the same as that of the U-shaped groove of the fork head of the connecting head. The outer diameter is the same. In the middle of the leak disc, there are ejection holes of fork rod connecting the fork head. The height of ejection holes and the height of the fork rod ejection holes and the length of the fork rod are the same. When in use, the punch is connected with the press, the concave die is placed on the leaky plate, the high temperature T-shaped blank is placed in the concave model cavity, the blank rod is inserted into the ejection hole of the demoulding die, the punch is pressed down, and the fork of the connecting head is forged out. The utility model saves raw materials, and the connecting head fork forged by the die of the utility model has regular shape, good metal streamline and short processing period. The utility model is suitable for die forging of various forks with T shape.

用于模锻连接头叉头的模具
本技术涉及一种用于模锻连接头叉头的模具。
技术介绍
连接头是煤矿液压支撑装置中的重要部件,工况特殊,受力复杂,不仅要有良好的力学性能,还要保证一定的形状,以满足特殊工作条件的需要,通常在压机上采用自由锻造成形,叉头部分锻一长方体,通过后续机加工加工出叉头U形凹槽,加工余量大,工时长,加工成本高,内部纤维组织不连续,力学性能较差。
技术实现思路
本技术的目的是针对上述现状,提供了一种锻造出的连接头叉头外形规则、材料利用率高、金属流线好、机加工时间短的用于模锻连接头叉头的模具。本技术目的的实现方式为,用于模锻连接头叉头的模具,有凸模、凹模,所述凸模上部的直径与连接头叉头的内径一致,下部形状与连接头叉头的U型槽形状一致;所述凹模有与连接头叉头外形形状一致的型腔,型腔中心有叉头杆顶出孔,叉头杆顶出孔的内径与连接头叉头的叉头杆外径一致;漏盘中间有连接头叉头的叉头杆脱模顶出孔,脱模顶出孔的高度与叉头杆顶出孔的高度和为叉头杆长度。使用本技术时,凸模与压机连接,凹模置于漏盘上,将高温充分保温的T形坯料放置在凹模型腔内,坯料杆部插入脱模顶出孔中,凸模下压,模锻 ...
