Solve the problem such as resistance strain gage easy fatigue damage during existing tonnage monitoring device forcing press punching press overload.Real by the present invention
Existing forcing press hits the indirectly measurement of tonnage, and installation and debugging are simple, and life-time service is without fallible component, and dynamic range is big simultaneously,
Fast response time, good in anti-interference performance.
It is an object of the invention to be achieved through the following technical solutions, a kind of forcing press punching press tonnage monitoring device, including
Circuit module in housing and housing, it is characterised in that fix the first contiguous block and second on the base plate in described housing and connect
Block, one end of the first contiguous block is fixed on corresponding one end of base plate, and one end of the second contiguous block is fixed on the other end of base plate；The
The free end of one contiguous block and the second contiguous block fixed permanent magnet, Hall element, permanent magnet and Hall element surface respectively
Relatively；The output of Hall element connects signal conditioning circuit in circuit module.
Described permanent magnet arranges one or more.
Described Hall element arranges one or more.
Described first contiguous block and the second contiguous block use low-permeability material.
Described second contiguous block and base plate or be integrated.
The operation principle of the present invention is, when forcing press hits, the base plate being fixed on machine pillar and body synch produce
Elastic deformation, the elastic deformation of base plate is delivered to the first contiguous block and the second contiguous block, the first contiguous block or the second contiguous block will
Certain proportion base plate elastic deformation is delivered to the Hall element being secured to connect, and the second contiguous block or the first contiguous block are by one
Certainty ratio base plate elastic deformation is delivered to the Magnet being secured to connect, and base plate elastic deformation can be analyzed to be parallel to forcing press and stands
The floor length direction on post surface and be perpendicular to the deformation of both direction of forcing press leg surface, due to Hall element and magnetic
Ferrum position is relative, and the magnetic field intensity that the deformation in floor length direction makes Hall element sense changes, therefore corresponding machine
The size hitting stress on bed column exports corresponding change in voltage through Hall element, and circuit module carries out modulus to voltage and turns
Changing through computing is that corresponding forcing press hits tonnage numerical value.Compared with prior art, advantage of the present invention is: achieves forcing press and beats
Hitting the indirectly measurement of tonnage, installation and debugging are simple, and life-time service is without fallible component, and dynamic range is big simultaneously, and certainty of measurement is high,
Fast response time, good in anti-interference performance.

Detailed description of the invention
For making the purpose of the present invention, technical scheme and effect clearer, clear and definite, below to the present invention the most specifically
Bright.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment one, the present embodiment structure as shown in Figure 1 and Figure 2, including first contiguous block the 5, second contiguous block 2, permanent magnet
3, Hall element 4, circuit module 1, base plate 6, housing 8, respective one end of the first contiguous block 5 and the second contiguous block 2 is solid respectively
Due to the two close end of base plate 6, permanent magnet 3 adhere to the second contiguous block 2 free end, Hall element 4 adheres to first even
Connecing the free end of block 5, Hall element 4 is relative with permanent magnet 3 position, and the output of Hall element 4 connects in circuit module 1 to be believed
Number modulate circuit, the first contiguous block 5 is corresponding with the fixing end of the second contiguous block 2 is fixed on base plate 6 two close end.
The inventive point that the embodiment of the present invention is most crucial: by base plate in the present invention 6 and first contiguous block the 5, second contiguous block 2
Position relation is set, by forcing press column produce elastic deformation pass through base plate the 6, first contiguous block the 5, second contiguous block 2
It is delivered to Hall element 4 and permanent magnet 3, utilizes non-contacting magnetic induction principle, Hall element 4 sensing output corresponding pressure
The elastically-deformable voltage signal of machine column.
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 8 connects, and base plate 6 is fixed on outside forcing press column or inner surface, during forcing press generation punching press action, and forcing press column
Then producing elastic deformation, owing to forcing press leg surface is fixed at base plate 6 two ends, base plate 6 then produces the elastic deformation of correspondence, by
Be individually fixed in the two close end of base plate 6 in the first contiguous block 5 and the second contiguous block 2, the first contiguous block 5 and the second contiguous block 2 pass
Pass corresponding base plate elastic deformation, and permanent magnet 3 adheres to the second contiguous block 2 surface, Hall element 4 adheres to the first connection
The surface of block 5, permanent magnet 3 is relative with Hall element 4 surface, and Hall element 4 occurs relative change in location with permanent magnet 3,
Hall element 4 exports corresponding voltage, and it is that corresponding forcing press hits that circuit module carries out analog digital conversion union to voltage
Tonnage numerical value.
Embodiment two is as it is shown on figure 3, its operation principle is identical with embodiment one with working method, with multiple in the present embodiment
The magnetic field combination of permanent magnet 3 composition replaces the scheme of single magnet, may be used without multiple Hall element 4 equally.The most also
Can be by the relative position in the direction of adjustment permanent magnet 3 magnetic pole with Hall element device 4, to improve precision and the line of systematic survey
Property.
In the present embodiment, the second contiguous block 2 and base plate 6 are same parts, and the i.e. second contiguous block 2 and base plate 6 are integrated,
At this moment the second contiguous block 2 is without free end, also can reach effect same, simply global facility processed complex.First contiguous block 5 and
The function of two contiguous blocks 2 can be exchanged, i.e. permanent magnet 3 adheres to the first contiguous block 5, and Hall element 4 adheres to the second connection
Block 2, also can reach effect same.
First contiguous block 5 and the second contiguous block 2, in the selection of material, are considered as selecting its thermal coefficient of expansion and forcing press
The material that the thermal coefficient of expansion of fuselage material is close, measures scope improving system dynamics further.
When actual installation uses, it is possible to tonnage monitoring is installed in the multiple some positions on a press frame column simultaneously
Device, can calculate the aggregation of data of multiple tonnage monitoring devices and be converted into the strike tonnage of forcing press.
As shown in Figure 4, in the present invention, circuit module 1 uses existing mature technology, processes circuit, signal including data operation
