Abstract
The invention relates to a flattening device for a welding opening of a protector steel jacket. The flattening device is used for flattening the welding opening of a welding part of an end thread protector of an oil casing and various pipes. The flattening device comprises a frame and a piston arranged on the frame, wherein a base is arranged at the bottom of the frame; the piston is connected with a flattening punch; a supporting table is arranged on the base opposite to the flattening punch; a stator is arranged between the flattening punch and the supporting table; dent arc surfaces are arranged on the end parts of the flattening punch and the supporting table; projected arc surfaces are arranged on the contact parts between the stator and the flattening punch as well as between the stator and the supporting table; a rear baffle is arranged on the base. The flattening device has the beneficial effects that the effect is good and the efficiency is greatly increased after the punching flattening is adopted.
Description
Technical field
The present invention is used for the pressing of petroleum casing pipe and all kinds of pipe end threading protectors welding positions weld bond.
Background technology
Steel pipe, in transportation, very easily causes damage to pipe end, in order to protect tube head, generally at pipe end suit pipe cap, is also protector.The processing of steel bushing is all cut with steel plate, then the welding of volume circle.Because high temperature action during welding makes weld bond protruding, affect steel loop circularity, therefore also needs butt welding mouth to process, past employing be that mode repaired by artificial hand hammer, not only working strength greatly, inefficiency and effect also bad.
Summary of the invention
The invention provides a kind of protector steel bushing weld bond pressuring flat device, adopt hydraulic pressure to flatten, decrease working strength, improve efficiency.
In order to achieve the above object, the technical scheme that the present invention takes is:
A kind of protector steel bushing weld bond pressuring flat device, comprises frame, is provided with base bottom frame; it is characterized in that: the piston that frame is provided with; piston connects pressing drift, and the base relative with flattening drift is provided with brace table, between described pressing drift and brace table, be provided with stator.
Above-described pressing drift and brace table end are provided with recessed arc surface, and described stator is provided with the arc surface of protrusion with pressing drift and brace table contact site.
Above-described base is also provided with a backboard.
The invention has the beneficial effects as follows, workpiece flattens post processing by hydraulic pressure, not only effective, and efficiency obtains large increase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. piston; 2. flatten drift; 3. frame; 4. backboard; 5. brace table; 6. base; 7. stator; 8. steel bushing.
Detailed description of the invention
From accompanying drawing 1, the present invention includes frame 3, bottom frame 3, be provided with base 6, piston 1 is provided with at the top of frame 3, piston 1 connects pressing drift 2, and the base 6 relative with flattening drift 2 is provided with brace table 5, between described pressing drift 2 and brace table 5, be provided with stator 7.Above-described pressing drift 2 and brace table 5 end are provided with recessed arc surface, and described stator 7 and the contact site flattening drift 2 and brace table 5 are provided with the arc surface of protrusion.When above-described pressing drift 2, stator 7 and brace table 5 contact, its face that contacts with each other matches.Steel bushing 8 is enclosed within stator 7, weld bond is upwards aimed at and flattens drift 2.Start piston 1, flatten drift 2 punching press downwards, weld bond can be flattened.Above-described base 6 is also provided with a backboard 4, barrier effect is played to the steel bushing 8 be placed on stator 7.
It should be noted that embodiment of the present invention is only its preferred embodiment, is only apparent change to belonging to technical solution of the present invention, all should belong within protection scope of the present invention.
