Abstract
The utility model discloses a pressing mold of gaps, in particular to a pressing mold for pressing gap on samples in drop weighted tear tests. The pressing mold comprises a pressing head, a pressing knife and a base, wherein a knife slit is arranged on the pressing head, the pressing knife is installed in the knife slit, and exposes the cutting edge part, the pressing head is installed on a pressing body of a pressing machine, and the base is installed on a cross beam platform of the pressing machine. The pressing mold can fast, conveniently and accurately press gaps on samples in drop weighted tear tests.
Description
Technical field
The utility model relates to a kind of compacting tool set of breach, a kind of specifically compacting tool set that is used in the Drop-Weight Tear Test (DWTT) sample break.
Background technology
When common steel being carried out the test of Drop-Weight Tear Test (DWTT) (DWTT) sample break, Drop-Weight Tear Test (DWTT) sample break processing mode, what present stage adopted is that hydraulic dynamometer is suppressed at sample break.In the process of operation, by observing scale, hand-screw changes the oil-feed handle.The shortcoming of this mode is, can not reliably control the compression distance of pressure head blade, speed is slow, skill level to the operator requires high, and the sample break position is by line centering location, not only time-consuming taking a lot of work, and be difficult for centering and place, pressing process very easily produces breach and crosses shallowly deeply excessively, and the sample crudy can not get effective control.
The utility model content
The purpose of this utility model be address the above problem and provide a kind of can be fast, convenient, process the device of Drop-Weight Tear Test (DWTT) sample compacting breach accurately.
The technical scheme that the utility model adopted is:
A kind of Drop-Weight Tear Test (DWTT) sample break compacting tool set, comprise pressure head, press sword and base, have a knife holder slot on the described pressure head, described pressure sword is installed in the knife holder slot, press sword to expose knife edge part, described pressure head is installed on the pressure head body of pressing machine, and described base is installed on the pressure machine cross-beam platform.
Preferably, described pressure sword is fixed in the knife holder slot by screw.
Further, the carrying plane length of described base is consistent with the sample maximum length, and centering is carved with the minimum length mark of sample on the carrying plane of base.
Further, the carrying plane of described base is made a parallel step along its length.
Preferably, described base is fixed on the pressure machine cross-beam platform by screw.
Preferably, on the described pressure head alarm is installed.
The utlity model has following advantage:
When this device carries out the breach compacting to the Drop-Weight Tear Test (DWTT) sample, do not need to measure, once just can be with the sample break moulding; Matching design becomes the sample support plinth of sample specified length, makes things convenient for sample to lay centering, and can guarantee that the length of sample is qualified; Be shaped on perpendicular to the base of compacting breach center line surface, guarantee that the breach after the processing is vertical with specimen surface with convenient location sample, thus reach fast, convenient, accurately process the process goal that the Drop-Weight Tear Test (DWTT) sample is suppressed breach.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is further described in detail.
Present embodiment is pipeline steel to be carried out the compacting of Drop-Weight Tear Test (DWTT) sample break.With reference to Fig. 1, the pressure head 2 of this device is installed on the pressure head body 1 of pressing machine, have one on the pressure head 2 knife holder slot 10 of pressing sword 6 is installed, because the breach of sample 3 has the certain technique standards specialized range, so knife holder slot 10 has the size of certain tolerance, pressing sword 6 to be close to knife holder slot 10 bottoms installs, fix with screw 5, same the fixing of sword 6 height of pressing also according to controlling dimension, thereby the knife edge part height value that exposes outside knife holder slot 10 end faces is controlled in the technical standard order scope of test 3 breach all the time, and sample 3 breach that suppress like this will guarantee standard fully.Impaired for preventing from time not shut down excessive sample 3 surfaces of causing of pressure, an alarm 9 can be set, pressure head 2 end faces with report to the police or cut off the electricity supply after sample 3 end faces contact.Base 4 is fixed on the pressing machine crossbeam platform 8, and is fixing by screw 7, because sample 3 has certain length, so base 4 carrying plane Design of length are become consistent with the maximum length of sample 3, made things convenient for accurate centering when laying sample 3 like this; Same sample 3 has certain length technical standard order scope, so centering is carved with the minimum length mark of sample 3 on base 4 carrying planes, can check just when laying sample 3 so whether sample 3 length are up to specification, in time check out substandard product; Base 4 carrying planes are made a parallel step along its length, and sample 3 suppresses breach when step end face is laid and sample 3 surfaces just in time are in vertical direction, so just can keep the correct shape of sample 3 breach.
When the work of this device, start pressing machine, press the pressure head 2 of sword 6 to act on sample 3 end faces with being equipped with, touch sample 3 end faces until pressure head 2 end faces, judge whether both ends of the surface contact to judge by pressing machine dynamometry dial plate pointer, when both ends of the surface contact, withdraw from pressure head 2, operation is finished.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
