Abstract
The utility model discloses a convoluted cold bending testing machine which is composed of a case, a reducing gear and a test sample clamping device. The test sample clamping device comprises a striking block, a rotary disk, a pressure roller, the center shaft of the pressure roller, the bending center shaft of the pressure roller, a bending center sleeve, a stroke switch, a positioning slot, a positioning block, a top thread, a test sample holding jaw plate, a bottom plate, etc. Compared with the existing three-point type cold bending testing machine, in the convoluted cold bending testing machine, the structural design is simple and novel, and the volume is small; the three-point type structure is changed into the convoluted type structure, which can overcome the defects that an oil cylinder is easy abrasion; a supporting roller is easy destruction; the precision is difficult to be guaranteed when the three-point type cold bending testing machine implement the test.
Description
The utility model belongs to cold bending test machine and makes the field, is specially adapted to the weld seam cold bend test and the pressure tight seam cold bend test of spiral submerged welded pipe.
Prior art in the utility model prior art field is: the bikini cold bending test machine, it is the pressure head of power, two rod structures that this machine adopts hydraulic pressure, and its weak point is: body is big, during test, oil cylinder is easy to a wearing and tearing rod and is easy to destroy, and test accuracy is difficult to guarantee.
Purpose of design of the present utility model is: avoid weak point of the prior art, design a kind of wound form cold bending test machine.
Design proposal of the present utility model is: the wound form cold bending test machine is to be made of housing, reduction gear and sample holder device, and housing and reduction gear belong to prior art, are not described herein at this.The sample holder device is to be made of collision block, rotary disk, pressure roller, pressure roller central shaft, flexual center axle, flexual center cover, travel switch, locating slot and locating piece, jackscrew, sample holder jaw plate, fixed leg, base plate, pad, bolt and pressure roller central shaft hole A.Rotary disk is rounded, and be shaped on the flexual center axis hole at the center of rotary disk, on the dish of rotary disk, be shaped on pressure roller central shaft hole and pressure roller central shaft hole A, the pressure roller central shaft is positioned at the pressure roller central shaft hole, pressure roller is enclosed within on the pressure roller central shaft, the flexual center axle passes housing and is connected with the reduction gear that is positioned at housing, rotary disk is enclosed within on the flexual center axle by the flexual center axis hole at rotary disk center, the flexual center cover is enclosed within on the flexual center axle, spacing between the axle center of the axle center of flexual center axle and pressure roller central shaft is 74～114mm, and the hole spacing in the heart of the axle center of pressure roller central shaft and pressure roller central shaft hole A is 123～163mm.Pressure roller and flexual center cover (pressure roller) are to be made of thin-walled needle bearing and roller shell; the thin-walled needle bearing is positioned at roller shell; wherein the diameter of pressure roller is greater than the diameter of flexual center cover; the flexual center cover has following specification according to wall thickness and flexual center diameter Relationship; see attached list 1, but collision block is positioned at the side of rotary disk cylindrical and by touching the nail left and right adjusting.Travel switch is fixed on the housing and with the side of rotary disk cylindrical and leaves the gap, and the connecting line of travel switch is connected by in prior art and the reduction gear.The effect of travel switch is: the one, and the counter-rotating of control rotary disk, the 2nd, the control rotary disk stops.The sample holder jaw plate by fixed leg and spacers on base plate, base plate is by being bolted on the housing, jackscrew is positioned on the jaw of sample holder jaw plate, and locating piece is positioned at the jaw of sample holder jaw plate, and the clamping jaw of sample holder jaw plate is positioned at the top of rotary disk.
The utility model compared with prior art, the one, structural design is novel simple, volume is little; The 2nd, changing the bikini structure is the wound form structure, thereby has overcome cold bending test machine when test of bikini structure, and oil cylinder is easy to wearing and tearing, the deficiency that a rod is easy to destroy, precision is difficult to guarantee, and its contrast test sees attached list 2.
