Abstract
The invention discloses a kind of tubing to be flared core ejecting device, the flaring core ejecting device includes the cone that apex angle is 30 ° or 60 °, a weld seam slot and a sipes are carved in cone, the interior side of the sipes is carved with altitude scale, and the diameter gauge for indicating extrapyramidal is carved in the other side.When test, tubing to be detected is placed in cone, the initial position of tubing is observed first on altitude scale or diameter gauge；Then diameter after calculating flaring depth according to enlarging rate or expand, position after expansion is drawn using slate pencil on altitude scale or diameter gauge；Finally start to test, until expanding tubing to after the expansion drawn at position, measuring diameter after tubing expands after the test.The present invention uses the flaring core ejecting device with altitude scale and diameter gauge, can internal diameter after the height or expansion that tubing to be detected needs after expanding from flaring core ejecting device directly, be adapted to the requirement of GB/T 242 and ASTM A450.
Description
Technical field:
The present invention relates to tubing detection technique fields, and in particular to a kind of tubing flaring core ejecting device is used for small-bore pipe
The flaring performance detection of material is tested.
Background technique:
With the application of the small diameter metals tubing such as continuous pipe, detection industry examines the mechanical property of this kind of metal pipe material
It surveys, in addition to conventional stretching, impact etc., it is also necessary to carry out the performance detection such as being flared.Tubing flared method standard requirements use one
The core ejecting device of angle is determined as flaring die.Currently, common core ejecting device is with groove with 30 ° or 60 ° angles or not
The plunger tip of with groove, the data detection system for needing cooperating equipment to have determine the height of flaring by crosshead displacement, thus
With reaching the mesh of control flaring rate.But this kind of method has place not easy to operate at two；First, this kind of method is needed in experiment opening
Sample is adjusted to just be bonded with equipment manually before beginning, process is relatively time-consuming while needing to observe always the laminating degree of sample；
Second, American Standard ASTM A450 is required, enlarging rate is calculated by pipe internal diameter, and when using common core ejecting device, flaring height is
It is converted into outer diameter calculating, it is more complicated.
Summary of the invention:
It is an object of the invention to overcome the above-mentioned prior art, a kind of tubing flaring core ejecting device, the dress are provided
It sets and is applicable not only to the tubing with tiny weld seam and carries out flaring test, and can directly observe and be needed after tubing to be detected expands
Internal diameter after height or expansion.
The purpose of the present invention is by the following technical programs to solve: a kind of tubing is flared core ejecting device, the flaring top
Core apparatus includes the cone that apex angle is 30 ° or 60 °, is carved with a weld seam slot and a sipes, the inside of the sipes in cone
Altitude scale is carved in side, and the diameter gauge for indicating extrapyramidal is carved in the other side.
Further, adjacent scribe line differs 1mm in altitude scale, and adjacent scribe line differs 1mm in diameter gauge.
The beneficial effects of the present invention are:
(1) flaring core ejecting device of the invention has weld seam slot, and the tubing with weld seam is enable to be stably placed at cone
On, suitable for having the tubing flaring test of tiny weld seam.
(2) since the software equipment of no measuring system is unable to measure the depth of flaring, standard can not accurately be obtained by, which causing, is wanted
The flaring rate asked, the present invention in order to solve this problem, can be from using the flaring core ejecting device for having altitude scale and diameter gauge
Internal diameter after the height or expansion needed after tubing to be detected expands is directly observed on flaring core ejecting device, and the present invention does not need equipment belt
Have system for monitoring displacement, only need equipment can provide it is enough compression or draw direction power test can be completed, substantially reduce
Requirement of the flaring test to equipment.
Detailed description of the invention:
Fig. 1 is the main view of tubing flaring core ejecting device.
Fig. 2 is the top view of Fig. 1.
Description of symbols: 1 cone, 2 weld seam slots, 3 scale slots, 4 altitude scales, 5 diameter gauges.
Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawing:
A kind of tubing is flared core ejecting device as Figure 1-Figure 2, which includes that apex angle is 30 ° or 60 °
Cone 1 is carved with a weld seam slot 2 and a scale slot 3 on the conical surface of cone 1, and the weld seam slot 2 can accommodate the weld seam of tubing,
The interior side of the scale slot 3 is carved with altitude scale 4, and the diameter gauge 5 for indicating extrapyramidal, high scale 4 are carved in the other side
Adjacent scribe line differs 1mm in ruler, and adjacent scribe line differs 1mm in diameter gauge.
The present invention can accommodate the weld seam slot 2 of tubing weld seam, be suitable for tubing flaring core ejecting device with tiny weld seam
Tubing flaring test.
The depth of scale slot 3 of the present invention is than shallower, it is possible to prevente effectively from the case where causing groove to wear due to repetition test.
It is currently preferred, scale slot 3 and the distribution in 90 ° of weld seam slot 2, as shown in Figure 1.
Altitude scale 4 of the present invention is suitable for 242 flaring test on tube of metal method of GB/T；Diameter gauge 5 is suitable for
ASTMA450 carbon steel, ferritic alloyed steel and austenitic alloy steel pipe General Requirement.
Before carrying out flaring test, present invention flaring core ejecting device stabilization is placed on testing machine crossbeam, and will be to be detected
Tubing be placed in cone, if tubing to be detected have weld seam, weld seam is gone into weld seam slot 2, it is ensured that pipe to be detected
Material horizontal stable.
When carrying out flaring test:
(1) if be first placed in the scale slot of cone 3 on one side according to 242 flaring test on tube of metal method of GB/T
Testing crew observes the initial position of tubing convenient for the position of observation on altitude scale 4；Then it is calculated and is flared according to enlarging rate
Depth draws position after expansion using slate pencil on altitude scale 4；Finally start to test, until expanding tubing to the expansion drawn
At position, diameter after tubing expands is measured after the test.
(2) first if when according to ASTM A450 carbon steel, ferritic alloyed steel and austenitic alloy steel pipe General Requirement
The scale slot of cone 3 is first placed in testing crew on one side convenient for the position of observation, the starting of tubing is observed on diameter gauge 5
Position；Then internal diameter after expanding is calculated according to enlarging rate, draws position after expansion on diameter gauge 5 using slate pencil；Finally start to try
It tests, until expanding tubing to after the expansion drawn at position, measuring diameter after tubing expands after the test.The present invention is flared plunger tip dress
The cone 1 set can be bonded tubing to be detected completely, and enlarging rate can directly be calculated by pipe internal diameter, avoid using existing common
Core ejecting device needs to convert into outer diameter and calculates.
Tubing of the present invention is flared core ejecting device and uses tool steel, and after modulation treatment, surface hardness >=45HRC can be weighed
It is multiple to use, and long service life.
