Block, base plate elastic deformation can be analyzed to parallel to the floor length direction of forcing press leg surface and perpendicular to forcing press column table
The deformation of the both direction in face, coil and metallic conductor block relative position change, due to eddy current effect, therefore correspondence lathe
The size then corresponding change of coil impedance generation of stress is hit on column, circuit module is measured and changed to coil impedance
For corresponding forcing press hits tonnage numerical value.Compared with prior art, advantage of the present invention is：Realize forcing press strike tonnage
Indirectly measurement, installation and debugging are simple, and, without fallible component, while dynamic range is big, certainty of measurement is high, response speed for long-term use
Hurry up, good in anti-interference performance.

Specific embodiment
To make the purpose of the present invention, technical scheme and effect clearer, clear and definite, below to the present invention further specifically
It is bright.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention is described in further detail with reference to the accompanying drawings and examples.
Embodiment one, the present embodiment structure as shown in Figure 1 and Figure 2, including lead by the first contiguous block 5, the second contiguous block 2, metal
Respective one end of body block 3, coil 4, circuit module 1, base plate 6, housing 8, the first contiguous block 5 and the second contiguous block 2 is fixed respectively
In the two close end of base plate 6, metallic conductor block 3 adheres to the free end of the second contiguous block 2, and coil 4 adheres to the first contiguous block 5
Free end, coil 4 is relative with the position of metallic conductor block 3.First contiguous block 5 is corresponding with the fixing end of the second contiguous block 2 to be fixed
In the two close end of base plate 6.
The most crucial inventive point of the embodiment of the present invention:By the contiguous block 5 of base plate in the present invention 6 and first, the second contiguous block 2
Position set relation, by forcing press column produce elastic deformation passed through base plate 6, the first contiguous block 5, the second contiguous block 2
Coil 4 and metallic conductor block 3 are delivered to, using non-contacting metallic conductor eddy current effect, by measuring inductance coil impedance variations
And it is converted into forcing press strike tonnage.
The both ends of base plate 6 be directly connected with forcing press column by screwed hole or be welded on forcing press column
Welding block 7 is connected, and base plate 6 is fixed on forcing press column outside or inner surface, when there is punching press action in forcing press, forcing press column
Elastic deformation is then produced, because forcing press leg surface is fixed at the two ends of base plate 6, base plate 6 then produces corresponding elastic deformation, by
The two close end of base plate 6 is individually fixed in the first contiguous block 5 and the second contiguous block 2, the first contiguous block 5 and the second contiguous block 2 are passed
Corresponding base plate elastic deformation is passed, and metallic conductor block 3 adheres to the surface of the second contiguous block 2, coil 4 and adheres to the first contiguous block
5 surface, metallic conductor block 3 and the end face of coil 4 are relative, and coil 4 and metallic conductor block 3 occur relative position change, coil 4
Impedance produces corresponding change, and circuit module 1 is measured to the impedance of coil 4 and is converted to corresponding forcing press strike tonnage number
Value.
Embodiment two is as shown in figure 3, its operation principle and working method are identical with embodiment one, but produce inductance induction reactance
The factor of change is changed into relative area from distance, in the present embodiment use triangle metal conductor block 3, and the end face of coil 4 with
The length direction of base plate 6 is parallel, and when forcing press occurs punching press action, forcing press column then produces elastic deformation, the end face of coil 4 and gold
The category relative distance of conductor block 3 is constant, but the area of the end face of 3 opposed coil of metallic conductor block 4 produces change, and the impedance of coil 4 is then
Corresponding change is produced, same effect is reached.
In this implementation process, the second contiguous block 2 and base plate 6 can be processed as same part, i.e. the second contiguous block 2 and base plate
6 are integrated, and at this moment the second contiguous block 2 can also reach effect same, but global facility processed complex without free end.Equally
The contiguous block 2 of metallic conductor block 3 and second can be processed as one structure, can also meet functional requirement.First contiguous block 5 and second
The function of contiguous block 2 can be exchanged, i.e., metallic conductor block 3 adheres to the first contiguous block 5, and coil 4 adheres to the second contiguous block 2,
Also effect same can be reached.
In implementation process, coil 4 can use common copper wire winding, it is also possible to straight from PCB multilayer boards
Connect and be designed to coil, high precision and uniformity is good, low cost scheduling and planning is simple.
