Abstract
The invention relates to an assembly and disassembly clamp for a puncher mandrel plug. The assembly and disassembly clamp is installed on the upper portion of the puncher mandrel plug. The assembly and disassembly clamp comprises a lever, rotary arms, hinge pins and a fixing ring. The fixing ring is installed on the upper portion of the puncher mandrel plug. The two rotary arms are fixedly and symmetrically connected to the lower portion of the fixing ring though the hinge pins correspondingly. The front portion of each rotary arm makes contact with the outside of the puncher mandrel plug. The rear portions of the rotary arms are connected with the lever. The assembly and disassembly clamp is simple in structure, capable of relieving the labor intensity and improving the work efficiency, easy to operate, low in production cost and long in service life.
Description
Technical field
The present invention relates to a kind of perforating steel pipe utility appliance, particularly relate to a kind of piercing mandrel plug loading and unloading clamp.
Background technology
Current each pipe mill adopts artificial hammer to beat very time-consuming, and labour intensity height, working efficiency is low, also easily strikes bad by top.
Summary of the invention
The present invention in order to overcome the above problems provide a kind of structure simple, reduce labour intensity, increase work efficiency, simple to operate, production cost is low, the piercing mandrel plug loading and unloading clamp of long service life.
The technical scheme of the present invention is: described loading and unloading clamp is arranged on piercing mandrel plug top, described loading and unloading clamp comprises lever, pivot arm, bearing pin and fixed ring, described fixed ring is arranged on piercing mandrel plug top, described pivot arm has two, it is connected to fixed ring bottom respectively by bearing pin fixed symmetrical, described pivot arm front portion contacts with piercing mandrel plug outside, and described pivot arm rear portion connects lever respectively.
Present configuration is simple, reduce labour intensity, increase work efficiency, simple to operate, production cost is low, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1 is lever, and 2 is pivot arm, and 3 is bearing pin, and 4 is fixed ring, and 5 is piercing mandrel plug.
Embodiment
