Description
Technical field
The utility model relates to a kind of auxiliary lifting appliance, especially relates to a kind of clamp of quick forging machine.
Background technology
Round steel blank is after quick forging machine forging and stamping, conventionally adopt clamp to hang quick forging machine, the specification of quick forging machine Workshop Production round steel is generally between 200-700, quick forging machine needs the often round steel blank of the various diameters of conversion forging and stamping, the tong arm of existing clamp as shown in Figure 6, tong arm comprise link rod part 1 ' and operate portions 2 ', link rod part 1 ' be straight-bar, operate portions 2 ' be circular arc, operate portions 2 ' and link rod part 1 ' between be provided with a circumscribed arc transition portion 3 ', due to interconnecting gangway 3 ' existence, use the clamp of this tong arm, when with clamp lifting small dimension round steel blank (small diameter), cannot clamp round steel blank and can only rest on clamp, very dangerous in handling process, especially the round steel blank that length is grown is easy to slide, not only can cause the reduction of work efficiency, even may draw safety misadventure.
Utility model content
The applicant, for above-mentioned problem, is studied improvement, and a kind of quick forging machine clamp is provided, simple and compact for structure, while lifting by crane large and small size round steel blank, all can clamp round steel blank, guarantee the safe and reliable of handling round steel blank, avoid the generation of safety misadventure, increase work efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of quick forging machine clamp, comprises two pairs of tong arms and two pairs of connecting rods, and upper axle, lower shaft, tween drive shaft be arranged in parallel, and the two pairs of tong arms and the two pairs of connecting rods are separately positioned on the two ends of axle, lower shaft, tween drive shaft accordingly; Described tong arm comprises link rod part and operate portions, and described link rod part is straight-bar, and described operate portions is circular arc, described link rod part and described operate portions is tangent connects as one; The middle part that forms two tong arms of a pair of tong arm is hinged on one end of lower shaft, and the outer end of the operate portions of two described tong arms is hinged on respectively same one end of two tween drive shafts; Form two connecting rods same one end of hinged two described tween drive shafts respectively of a pair of described connecting rod, one end of the hinged upper axle of the other end of two described connecting rods; The outside that is positioned at the operate portions of two corresponding tong arms at lower shaft two ends is provided with spacing pipe link, and suspension ring connect described upper axle.
Further:
Be hinged between the described tong arm of same axle head, between described connecting rod or between described tong arm and described connecting rod, be provided with pad.
Technique effect of the present utility model is:
The disclosed a kind of quick forging machine clamp of the utility model, simple and compact for structure, while lifting by crane large and small size round steel blank, all can clamp round steel blank, guarantee the safe and reliable of handling round steel blank, avoid the generation of safety misadventure, increase work efficiency.
