Abstract
The utility model discloses a sample positioning device for a drop weight impact tester, which solves the problem that centering of a punch and a cup sample is hard to complete in 3 seconds in a drop weight impact test. The sample positioning device comprises a punch, a cup sample and an anvil block, a positioning plate is mounted on the anvil block, a positioning hole is arranged in the middle of the positioning plate, the cup sample is placed in the positioning hole, the center of the positioning hole and the center of the punch are on the same vertical line, the diameter of the positioning hole corresponds to that of the testing cup sample, and a handle is arranged on one side of the positioning plate. During the test, the cup sample is quickly placed in the positioning hole after being picked out from a low-temperature tank, the punch is released at the moment the cup sample is placed in the positioning hole, the impact test is over in 3 seconds, and the centering is accurate. The handle arranged on one side of the positioning plate facilitates picking and placing the positioning plate.
Description
Technical field
The utility model relates to a kind of drop hammer impact testing machine, relates in particular to a kind of drop hammer impact testing machine sample locating device.
Background technology
Existing drop hammer impact testing machine is mainly used in the secondary processing embrittlement characteristic of check and analysis drawing with gapless atomic steel and phosphor intensified steel.Gapless atomic steel and phosphor intensified steel plate have certain internal stress after drawing, be subjected to external force to do the time spent, and the power effect that particularly is hit under the cryogenic conditions is ruptured at the crystal boundary place easily.
Drop hammer impact testing machine mainly comprises four parts: pedestal, column, tapered punch and releasing mechanism.Its principle of work is, the cup sample that will be incubated certain hour in cryostat, places on the pedestal, rim of a cup up, drift falls from eminence, provides particular energy and impacts a cup sample.Test temperature by continuous reduction drop impact is broken until the cup sample, measures the secondary processing brittle temperature of steel plate.Impulse test should be carried out in 3 seconds at a taking-up cup sample from cooling bath.Therefore to complete successfully single test, need to solve two subject matters: sample centering, even the center of the center of sample and drift on a perpendicular line, and attack time≤3 second.
In usual test, sample centering is mainly with operating personnel's eyesight, sensation and skill level etc.In the so short time, sample is difficult to centering.Sample does not have centering, and then experimental result is disperseed, and end product is an invalidate the test.Centering but spended time is overtime, or spended time is short but do not have centering, last result all is invalidate the tests.
The utility model content
The purpose of this utility model is to overcome the prior art defective, and a kind of drop hammer impact testing machine sample locating device is provided, to realize sample and the quick centering of drift.
The technical solution of the utility model is achieved in that drop hammer impact testing machine sample locating device, comprise drift, cup sample, anvil block, it is, on anvil block, be equipped with location-plate, have pilot hole in the middle of the described location-plate, the cup sample is placed in the pilot hole, and the center of pilot hole and drift center are on a perpendicular line, and the pilot hole diameter adapts with cup sample diameter with test.
Preferably, described location-plate one side jug.
In process of the test, a cup sample takes out from cryostat,, puts into pilot hole rapidly, puts into the abrupt release drift of pilot hole at the cup sample, and impulse test finished within 3 seconds, and the centering accurate positioning.
Description of drawings
Accompanying drawing 1 is the utility model connection diagram.
Accompanying drawing 2 is location-plate synoptic diagram.
Among the figure, the 1-drift; 2-cup sample; The 3-anvil block; The 4-location-plate; The 5-pilot hole; The 6-bolt hole; The 7-handle
Embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, select a thick steel plate of 4mm to make location-plate 4, its size is consistent with anvil block 3, location-plate 4 is installed on the anvil block 3 by four jiaos of four bolts hole 6, have pilot hole 5 in the middle of the location-plate 4, pilot hole 5 diameters are consistent with cup sample 2 diameters with test, are used for placing cup sample 2.In process of the test, test glass sample 2 takes out from cryostat,, directly puts into pilot hole 5, the center of pilot hole 5 and drift 1 center are on a perpendicular line, do not need to take time again and judge whether centering of sample, impulse test finished within 3 seconds, and the centering accurate positioning.Location-plate 4 one side jugs 7 when being used to change location-plate 4, conveniently pick and place location-plate 4.
Claims (2)
1. drop hammer impact testing machine sample locating device, comprise drift, cup sample, anvil block, it is characterized in that: on anvil block, be equipped with location-plate, have pilot hole in the middle of the described location-plate, the cup sample is placed in the pilot hole, the center of pilot hole and drift center are on a perpendicular line, and the pilot hole diameter adapts with cup sample diameter with test.
2. drop hammer impact testing machine sample locating device according to claim 1 is characterized in that: described location-plate one side jug.
