Description

The device of simplicity detection metal material Brinell hardness
Technical field
The present invention relates to technical field of detection of metal, especially a kind of dress of easy detection metal material Brinell hardness Put.
Background technology
Generally, metallic material product is the requirement for meeting performance, and its matrix must be detected after the heat treatment Hardness.But, for some live dimensions than larger parts, such as the hot-work die of some large-scale forging parts and one Crude product after a little conditioning treatments, to requiring that part hardness value scope makees a probably real visual inspection on drawing, with Just the hardness performance index of product is quickly judged, the final machining and heat treatment for next step provide valuable technology number According to.But, current detection scheme when for volume is big, weight is big part product, it is necessary to lift be placed on it is special large-scale The hardness of part is detected on ball hardness testing machine, is wasted time and energy inefficient.
The content of the invention
The purpose of the present invention is：A kind of device of easy detection metal material Brinell hardness is provided, it can quickly be tested out The hardness number scope of metal product, without complicated frock, and detection mode is simple, to overcome the deficiencies in the prior art.
What the present invention was realized in：Outside the device of simplicity detection metal material Brinell hardness, including cylinder shell, cylinder The axially middle part of shell is smooth through-hole structure, and impact bar is provided with the through hole of cylinder shell, and the end of impact bar is in cylinder Outside body case, round platform is provided with the front end of impact bar；Positive stop lug boss is provided with through-hole structure, between round platform and positive stop lug boss Provided with the spring around impact bar, standard specimen test block is provided with the front end of impact bar, top is provided with the other end of standard specimen test block Bar.
Handle is provided with 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 push rod shock sample test block When the hole that produces be not more than the diameter of standard specimen test block.
As a result of above technical scheme, the present invention devises a set of suitable simple and fast detection metal parts hardness model The device enclosed, using push rod shock sample test block and part simultaneously, after being hit by comparing part and standard specimen test block Circular hole size, then can intuitively judge the hardness level relation of part and standard specimen test block, so as to be quick detection large scale The hardness range of part, without special frock, and operation is simple for detection.The present invention is simple in construction, with low cost, makes It is good with effect.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
Embodiment
Embodiments of the invention：The structure of the device of simplicity detection metal material Brinell hardness is as shown in figure 1, including cylinder Shell 1, the axially middle part of cylinder shell 1 is smooth through-hole structure 2, and impact bar 3, punching are provided with the through hole of cylinder shell 1 The end for hitting bar 3 is in outside cylinder shell 1, and round platform 4 is provided with the front end of impact bar 3；Positive stop lug boss is provided with through-hole structure 2 5, the spring 6 around impact bar 3 is provided between round platform 4 and positive stop lug boss 5, standard specimen test block is provided with the front end of impact bar 3 7, push rod 8 is provided with the other end of standard specimen test block 7, the two ends of push rod 8 are circular arc, and its arc radius is not more than the diameter of push rod 8； It is provided with the end of impact bar 3 in handle 9, the present embodiment, handle 9 is made of a nut, between the nut and impact bar 3 For threaded connection, it is easy to be loaded onto or pulls down.
When in use, the outer end of push rod 8 is directed at part 10 to be measured, then pulled out impact bar 3 by handle 9, Positive stop lug boss 5 of the round platform 4 of the front end of impact bar 3 into through-hole structure 2 is moved, so that compression spring 6, is decontroled after handle 9, spring 6 drive returns of impact bar 3, and standard specimen test block 7 is hit, standard specimen test block 7 is hit push rod 8, push rod 8 then hits to be measured zero Part 10, push rod 8 applies almost equal impact to standard specimen test block 7 and part to be measured 10, while in standard specimen test block 7 and treating Survey on part 10 and leave shock impression, by comparing the size of the shock impression diameter on standard specimen test block 7 and part to be measured 10, It then can determine whether whether the Brinell hardness of part 10 to be measured is higher or lower than the Brinell hardness of standard specimen test block 7, so as to obtain one Whether accurate value range, required with judging the Brinell hardness of part 10 to be measured to meet as defined in technical conditions.For example, certain One part 10 to be measured, requirement as defined in technical conditions is that the ball hardness number of the part 10 to be measured cannot be below 300, then choosing The standard Brookfield hardness test block that a Brinell hardness is 300 is taken as standard specimen test block 7, the device of the present embodiment as described above Afterwards, if part to be measured 10 hit impression diameter be less than the standard specimen test block 7 shock impression diameter, illustrate this to be measured zero The Brinell hardness of part 10 is more than 300, then its hardness number meets requirement as defined in technical conditions；If otherwise part to be measured 10 is hit The shock impression diameter that impression diameter is more than the standard specimen test block 7 is hit, then illustrates that the Brinell hardness of the part 10 to be measured is less than 300, do not meet requirement as defined in its technical conditions.
The embodiment of the present invention being not limited to described in embodiment, those skilled in the art are according to the present invention Technical scheme draw other embodiments, also belong to the present invention technological innovation scope.Obvious those skilled in the art Member can carry out various changes and modification to the present invention without departing from the spirit and scope of the present invention.So, if the present invention These modifications and modification belong in the range of the claims in the present invention and its equivalent technologies, then the present invention is also intended to comprising these changes Including modification.
