The top center of steel pipe and the center of pressure head are caused the bias of ram pressures, so used for a long time not on same vertical curve
The service life of testing machine can be badly influenced afterwards.
Utility model content
The purpose of this utility model is to provide a kind of steel pipe flattening test machine, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of steel pipe flattening test machine, including hydraulic pressure
Machine body, the lower end of the hydraulic press body telescopic hydraulic cylinder is fixedly connected with pressure head, the table of the hydraulic press body
Face, which is located at immediately below pressure head, is fixedly connected with backing plate, and the both sides of the backing plate are arranged with parallel respectively is fixedly connected on hydraulic press
The stopping means of body table surface.
It is preferred that, the both side surface of the hydraulic press body is parallel respectively to offer preformed hole.
It is preferred that, the stopping means includes being constituted with sloping sliding seat by two pieces, and oblique on two pieces of sliding seats
Slope is symmetrical arranged composition V-shape.
It is preferred that, the upper and lower part of the side surface of sliding seat one has been respectively fixedly connected with expansion link, and expansion link
One end is fixedly connected with fixed seat.
It is preferred that, telescopic is fixedly connected with the middle part of the side surface of sliding seat one, the inside of the telescopic is installed
There is spring.
It is preferred that, the fixed seat is fixedly connected on the work top of hydraulic press body.
Technique effect of the present utility model and advantage：The steel pipe flattening test machine, passes through the stopping means and hydraulic pressure of setting
Preformed hole on machine body, it is spacing when being easy to the steel pipe to flatten, ignore the difference of diameter of steel tube, centralized positioning is accurate, prevents liquid
Press bulk density is eccentric, extends the service life of flattening test machine.
