Description
Technical field
The utility model relates to technical field of detection of metal, especially a kind of device of easy detection metal material Brinell hardness.
Background technology
Usually, metallic material product is the requirement meeting usability, must detect the hardness of its matrix after the heat treatment.But, for the parts that more on-the-spot dimensions are larger, thick product after the hot-work die of such as some large-scale stamp works and some conditioning treatments, to drawing requiring part hardness value scope makes a general real visual inspection, to judge fast the hardness performance index of product, for next step final machine work and thermal treatment provide valuable technical data.But current detection scheme is when, that weight large part product large for volume, and need lifting to be placed on the hardness special large-scale ball hardness testing machine detecting part, the efficiency that wastes time and energy is not high.
Summary of the invention
The purpose of this utility model is: the device providing a kind of easy detection metal material Brinell hardness, and it can test out the hardness number scope of metal product fast, and without the need to the frock of complexity, and detection mode is simple, to overcome the deficiencies in the prior art.
The utility model is achieved in that the device of easy detection metal material Brinell hardness, comprise cylinder shell, the axis middle part of cylinder shell is smooth through-hole structure, impact bar is provided with in the through hole of cylinder shell, the end of impact bar is in outside cylinder shell, is provided with round platform in the front end of impact bar; In through-hole structure, be provided with positive stop lug boss, between round platform and positive stop lug boss, be provided with the spring around impact bar, be provided with standard specimen test block in the front end of impact bar, be provided with push rod at the other end of standard specimen test block.
Handle is provided with at the end of impact bar.
Described push rod two ends are circular arc, and its arc radius is not more than push rod diameter.Make the hole produced during push rod shock sample test block can not be greater than the diameter of standard specimen test block.
Owing to have employed above technical scheme, the utility model devises the device that a set of applicable simple and fast detects metal parts durometer level, utilize push rod shock sample test block and part simultaneously, by the circular hole size after comparing part and standard specimen test block and being hit, then can judge the hardness level relation of part and standard specimen test block intuitively, thus be the durometer level detecting fast large-scale part, and without the need to special frock, and detect that operation is simple.The utility model structure is simple, and with low cost, result of use is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of the device of easy detection metal material Brinell hardness as shown in Figure 1, comprise cylinder shell 1, the axis middle part of cylinder shell 1 is smooth through-hole structure 2, impact bar 3 is provided with in the through hole of cylinder shell 1, the end of impact bar 3 is in outside cylinder shell 1, is provided with round platform 4 in the front end of impact bar 3; Positive stop lug boss 5 is provided with in through-hole structure 2, between round platform 4 and positive stop lug boss 5, be provided with the spring 6 around impact bar 3, be provided with standard specimen test block 7 in the front end of impact bar 3, be provided with push rod 8 at the other end of standard specimen test block 7, push rod 8 two ends are circular arc, and its arc radius is not more than push rod 8 diameter; Be provided with handle 9 at the end of impact bar 3, in the present embodiment, handle 9 adopts a nut to make, and for being threaded between this nut with impact bar 3, is convenient to be loaded onto or pull down.
In use, part 10 to be measured is aimed in the outer end of push rod 8, then by handle 9, impact bar 3 is pulled out, the round platform 4 of impact bar 3 front end moves to the positive stop lug boss 5 in through-hole structure 2, thus Compress Spring 6, after decontroling handle 9, 6, spring drives impact bar 3 return, and clash into standard specimen test block 7, standard specimen test block 7 is made to hit push rod 8, push rod 8 hits part 10 to be measured, push rod 8 applies almost equal impact to standard specimen test block 7 and part to be measured 10, on standard specimen test block 7 and part to be measured 10, leave shock impression simultaneously, by comparing the size of the shock impression diameter on standard specimen test block 7 and part to be measured 10, then can judge that the Brinell hardness of part 10 to be measured is whether higher or lower than the Brinell hardness of standard specimen test block 7, thus obtain a value range comparatively accurately, to judge the requirement whether Brinell hardness of part 10 to be measured meets technical conditions and specify.Such as, a certain part to be measured 10, the requirement that technical conditions specify is, the ball hardness number of this part 10 to be measured can not lower than 300, so choose a Brinell hardness be the standard Brookfield hardness test block of 300 as standard specimen test block 7, after the device of the present embodiment as above, if the shock impression diameter of part to be measured 10 is less than the shock impression diameter of this standard specimen test block 7, then illustrate that the Brinell hardness of this part 10 to be measured is greater than 300, then its hardness number meets the requirement that technical conditions specify; If otherwise the shock impression diameter of part to be measured 10 is greater than the shock impression diameter of this standard specimen test block 7, then illustrates that the Brinell hardness of this part 10 to be measured is less than 300, do not meet the requirement that its technical conditions specify.
Described in the utility modelly be not limited to the embodiment described in embodiment, those skilled in the art draw other embodiment according to the technical solution of the utility model, belong to technological innovation scope of the present utility model equally.Obvious those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
