The utility model relates to a large forging Tong, which has two symmetrical tong arms, a horizontal plate and a tong claw to form a tong body. The two clamp arms are connected by connecting pins and washers, the clamp arms are fixed and connected with the cross plate, and the two ends of the cross plate are fixed and connected with the upper part of the clamp claw; the clamp claw is of arc-shaped structure, and the rotating axis of the arc-shaped rib plate is screwed into the eccentric blind hole of the arc-shaped rib plate through the through holes in the middle and lower part of the clamp claw, and the arc-shaped rib plate is in the clamp claw; the arc-shaped rib plate can rotate freely around the rotating axis of the rib plate, and the arc-shaped rib plate is always in the rotating process Inward. This Tong adopts eccentric blind hole, so that during the use of arc rib plate, the arc opening is always toward the inside of the jaw, so as to clamp the forging, increase the contact area with the arc surface of the workpiece, and protect the workpiece from being clamped. The arc surface and plane of the arc rib plate of the tong can be used for hoisting workpieces with arc surface and plane characteristics. The tongs are universal and can safely lift workpieces with different shapes. When holding high-temperature workpieces, the surface damage of workpieces can be effectively reduced.

大锻件吊钳
本技术属于起吊锻件的吊具,具体涉及一种大锻件吊钳。
技术介绍
在锻造生产过程中,吊钳是起吊大型工件的必需工装,常规吊钳只能夹持形状较简单的毛坯工件,钳爪与工件接触面积较小,导致在吊起高温工件时较易夹伤。对于普通自由锻毛坯,因余量较大,可以不考虑吊钳夹持锻件时对表面造成的损伤,但是对于余量小的模锻件,高温起吊时合理的保护表面不被夹伤,十分关键。CN207016354U公开了一种可自动开合的吊钳,包括两个爪体,且两个爪体通过销轴铰接,所述爪体的两侧均设有长条块,两个长条块通过多个连接板连接,所述长条块靠近爪体的侧面开设有滑槽,两个滑槽之间设有两个滑块,且滑块的两端分别沿着两个滑槽的表面滑动,两个滑块之间安装有第二弹簧,所述爪体的侧面开设有与滑块匹配安装的长条孔,且滑块的表面沿着长条孔的内表面滑动,所述爪体的顶端通过销轴铰接有连接杆,所述连接杆的上方设有安装块。它能方便钳爪在为未夹持物体的状态下自动张开,提高对毛坯件起吊的效率。
技术实现思路
本技术的目的是针对上述现状,旨在提供一种可以安全起吊具有弧面形状等形状较复杂工件,在夹持高温工件时,能降低产品表面损伤程度的大锻件吊钳。本技术目的的实现方式为,大锻件吊钳,钳体由钳臂、横板和钳爪构成;两个钳臂通过连接销和垫片连接,钳臂与横板固定连接,横板两端与钳爪上部固定连接;钳爪为弧形结构,弧形筋板转轴通过钳爪中部和下部的通孔,旋入弧形筋板的偏心盲孔,弧形筋板的弧面在钳爪内;弧形筋板可绕筋板转轴自由旋转,旋转过程中,弧形筋板的弧面始终 ...
