Abstract
The utility model discloses a spring sheet for a balance. The spring sheet for the balance is characterized by comprising a panel with heat treatment. The panel comprises a middle part; one end of the middle part is connected with a first connecting part via a connecting part; the other end of the middle part is connected with a second connecting part via the connecting part; and the upper surface and the lower surface of the connecting part are respectively provided with an arc-shaped surface. The spring sheet for balance is to overcome deficiencies in the prior art and to provide a simply structured spring sheet for the balance with high stress relaxation stability, small deformation and high size precision as well as sensitivity.
Description
Technical field
The utility model relates to a kind of spring sheet for balance.
Background technique
Reed is the key components and parts that whether balance is accurate, whether performance is good, is " heart " of balance; Thereby the processing technology of reed and manufacture the weighing performance that measure of precision affects balance deeply.Yet the reed of producing under existing stamping process condition, in signal reaction, the antifatigue limit, the aspect such as balance, minimal thickness more and more can not meet existing production requirement again, therefore existing balance reed is further improved.
Model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of simple in structure, and stress relaxation stability is high, and deformation is little, and dimensional accuracy is high, the spring sheet for balance that susceptibility is high.
In order to achieve the above object, the utility model adopts following scheme:
A kind of spring sheet for balance, it is characterized in that: include through heat treated sheet material, described sheet material includes middle part, one end, described middle part is connected with the first joint by joint, the described middle part the other end is connected with the second joint by joint, on described joint upper and lower faces, is respectively equipped with arc shaped surface.
A kind of spring sheet for balance as above, is characterized in that being respectively equipped with attachment hole on the first joint and the second joint.
A kind of spring sheet for balance as above, is characterized in that being respectively equipped with attachment hole on the first joint and the second joint.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model new structure is simple, and distortion and the dimension overproof that can effectively avoid reed to cause because of heat treatment, can farthest obtain required size reed; Improve limit of elasticity and reduce elastic hysteresis, and strongly improving the combination properties such as stress relaxation stability; Reduce reed thickness, thereby improve reed susceptibility.The quality and the performance that have greatly promoted day flat products, improved factory inspection up-to-standard rate.
Accompanying drawing explanation
Fig. 1 is interarea schematic diagram of the present utility model;
Fig. 2 is side schematic view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing explanation and embodiment, the utility model is further described:
A kind of spring sheet for balance as shown in Fig. 1 to 2, include through heat treated sheet material 1, described sheet material 1 includes middle part 2,2 one end, described middle part are connected with the first joint 4 by joint 3, described middle part 2 the other ends are connected with the second joint 5 by joint 3, on described joint 3 upper and lower faces, are respectively equipped with arc shaped surface 6.
In the utility model, on the first joint 4 and the second joint 5, be respectively equipped with attachment hole 7.
In the utility model, sheet material 1 strikes out after External Shape, and through Overheating Treatment, sheet material 1 is reprocessed out arc shaped surface 6 shown in position 3.Distortion and dimension overproof that the utility model has effectively avoided reed to cause because of heat treatment, can farthest obtain required size reed; Improve limit of elasticity and reduce elastic hysteresis, and strongly improving the combination properties such as stress relaxation stability; Reduce reed thickness, thereby improve reed susceptibility.The quality and the performance that have greatly promoted day flat products, improved factory inspection up-to-standard rate.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
