The invention relates to a specimen notch presser, comprising a base, a support board, a support sleeve, a press knife, a press rod, a pressure plate and a return spring, wherein the support plate is fixed on the base, the support sleeve vertical to the base is fixed on the support plate, the press rod penetrates through the support sleeve, of which the upper end is mounted with the pressure plate and the lower end is mounted with the press knife, the press rod between the support sleeve and the pressure plate is sheathed by the return spring, the press knife is provided with a V-shaped cutting edge which two sides are provided with a protruded stop platform. The press rod is mounted with a notch depth measurement percent meter via a meter support. The notch depth can be limited by the knife to reliably control the specimen notch depth in a standard range and can display real-time depth. The specimen notch presser has accurate pressed specimen notch depth, high notch press speed and improved working efficiency.
Description
Technical field
The present invention relates to a kind of metal material shock resistance mechanics performance test apparatus, specifically a kind of sample break pressing machine.
Background technology
We know that for the relevant mechanical property of material is tested, people have designed the testing machine of various test material mechanical properties.Landing impact testing machine or Charpy impact machine tester are the visual plants in the metal material shock resistance mechanics performance test process.Various samples are absolutely necessary in the test process.Wherein, the sample that has the Drop-Weight Tear Test (DWTT) that is specifically designed to ferritic steel to use.To suppress V-notch on this sample, at present, the compacting of this type of V-notch generally all adopts a kind of simple and easy V-arrangement push type broach to suppress on pressing machine, before compacting, draw a groove with height gauge at the precompressed depth location earlier, when arriving the groove position, push type broach thinks the arrival standard depth, it is crooked that but groove can produce under the pressure of push type broach, all overgauge requirements of notch depth that general compacting is come out.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy for operation, and the compacting of the sample break degree of depth is accurate, and the breach pressing speed is fast, the sample break pressing machine of high efficiency.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of sample break pressing machine, it comprises base, back up pad, support set, push type broach, depression bar, platen, back-moving spring, back up pad is fixed on the base, support set perpendicular to base is fixed on the back up pad, it is characterized in that: depression bar runs through support set, platen is installed in its upper end, push type broach is installed in the lower end, depression bar outer cover between support set and platen is provided with back-moving spring, push type broach is provided with the V-arrangement blade, and the both sides of V-arrangement blade are provided with the termination platform of protrusion.
Also one notch depth is installed on the depression bar of the present invention and is measured dial gauge by dial framework.
The present invention adopts the push type broach of the termination platform of band protrusion, and the difference in height that stops between platform and V-arrangement blade is exactly the V-notch degree of depth that will suppress, in addition, adopts dial gauge tracking measurement notch depth.Against existing technologies, notch depth of the present invention can be limited by cutter itself, can reliably the sample break degree of depth be controlled in the standard-required scope, and can show real-time deep at any time.The compacting of the sample break degree of depth is accurate, and the breach pressing speed is fast, has improved work efficiency greatly.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of push type broach of the present invention.
Label among the figure is 1. platens, 2. back-moving spring, and 3. support set, 4. base, 5. push type broach, 6.V shape blade 7. stops platform, 8. back up pad, 9. sample, 10. dial framework, 11. clamping levers, 12. dial gauges, 13. depression bars, 14. fastening screws.
Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of sample break pressing machine, it comprises base 4, back up pad 8, support set 3, push type broach 5, depression bar 13, platen 1, back-moving spring 2 etc.Back up pad 8 is fixed on the base 4, and base 4 is used for carrying whole suppressor and lays sample 9.Support set 3 perpendicular to base 4 is fixed on the back up pad 8.
As shown in Figure 3, push type broach 5 is provided with V-arrangement blade 6, and the both sides of V-arrangement blade 6 are provided with the termination platform 7 of protrusion.Like this, the difference in height that stops platform 7 and 6 of V-arrangement blades is exactly the V-notch degree of depth that will suppress, touches on the sample behind the end face when stopping platform 7, owing to stop the resistance of platform, blade can not continue past pressing down, and promptly defines the degree of depth.Notch depth can be limited by cutter itself, can reliably the sample break degree of depth be controlled in the standard-required scope.The termination platform 7 of the protrusion that both sides are provided with makes notch depth not be subjected to sample to produce crooked influence under push type broach pressure, and the notch depth compacting accurately.
Also a notch depth is installed on the depression bar 13 of the present invention and is measured dial gauge 12 by dial framework 10.Platen 1, depression bar 13, push type broach 5 and dial gauge 12 are fixedlyed connected, and can move up and down simultaneously.Adopt dial gauge tracking measurement notch depth, can show real-time deep at any time, and the compacting degree of depth of compacting breach is with in decision at any time.
Also be provided with the sample clamp device on the base 4 of the present invention, so that firmly fix sample.Clamping lever 11 is used to clamp sample.
Use of the present invention is: at first the sample that will suppress is installed and clamps according to position illustrated in figures 1 and 2, with the light platen 1 that promotes of have gentle hands, make end face on the V-arrangement blade 6 contact samples 9 on the push type broach 5 downwards.Adjusting dial gauge 12 makes the table bar be pressed in the last end face of sample 9 and mix up zero point.When compressing into sample downwards under the pressure of blade at pressing machine, the table body of dial gauge moves down synchronously with depression bar 13 grades, and the table bar of dial gauge is pressed in end face on the sample all the time, like this indicator just can demonstrate blade from the sample end face to the inner mobile degree of depth of sample.The degree of depth of breach can be by the structure control of push type broach 5 itself, and knife edge part is calibrated altitude with the difference in height that stops platform, touches on the sample 9 behind the end face when stopping platform 7, can not continue promptly to define the degree of depth toward pressing down owing to stop the resistance blade of platform 7.After compacting finished, push type broach, dial gauge, depression bar resetted under the promotion of back-moving spring 2, and can unload sample and another piece sample of clamping that suppresses this moment.
Sample break degree of depth compacting of the present invention is accurate, and the breach pressing speed is fast, has improved work efficiency greatly.
