Description
Technical field
The utility model belongs to auto parts machinery technical field, especially relates to a kind of punching press spring sheet.
Background technique
Spring is the part that utilizes the elastic reaction of material to make, and deformation can occur under external force, removes after external force restorable mechanical parts again.In order to control parts motion, relax and impact or the size of vibrations, storage or saving energy, measuring force etc., be widely used in the equipment such as air conditioner in medical apparatus, auto parts and components and daily life.For example, in the seat of automobile, when moving forward and backward, can set up by automobile a spring sheet, this spring sheet plays a part resilience, this spring sheet has labour-saving advantage, and its structure of existing spring sheet is comparatively complicated and difficult installation and location, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of seat moving device [application number: 201120281906.7], comprise the base being fixed on seat cushions and the handle device coordinating with this base, on described handle device, comprise a rotating metallic rod and be fixed on the slug on automobile, one end of metallic rod is provided with a torsion spring, one end of torsion spring is fixed in metallic rod, and the other end of torsion spring is fixed on slug.Although above-mentioned scheme has been improved prior art to a certain extent, it also at least there is complex structure and be difficult for installation, high in cost of production problem in this scheme.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of design more rationally and the low punching press spring sheet of cost.
For achieving the above object, the utility model has adopted following technical proposal: this punching press spring sheet comprises by an elastic plate suppresses the elastomer forming, it is characterized in that, described elastomer comprises and is splayed shape and symmetrically arranged the first elastic strip body and the second elastic strip body, between the first described elastic strip body and the second elastic strip body, be connected by the arc elastic lamellar body that is arch, have respectively to the limit ear of arc elastic lamellar body protrusion direction turnover away from the both sides, one end of arc elastic lamellar body at the first elastic strip body, described limit ear is parallel to each other and is all vertical with the first elastic strip body, the shaft axis that has positioning hole and this positioning hole on the ear of each limit overlaps, there is breach at the second elastic strip body away from one end of arc elastic lamellar body, on the first elastic strip body, be also provided with between some teeth of the one end away from arc elastic lamellar body and adjacent two teeth and form teeth groove.Arc elastic lamellar body can prevent that bending from fractureing, and breach can be convenient to installation and removal, and teeth and teeth groove design can reduce area of contact, and long service life and stability are better.
In above-mentioned punching press spring sheet, described arc elastic lamellar body middle part has waist hole.Weight reduction and reducing costs under the prerequisite that meets usage requirement.
In above-mentioned punching press spring sheet, the bore of the opening of described breach is less than the internal diameter of breach.This structure is difficult for departing from.
In above-mentioned punching press spring sheet, described the first elastic strip body, the second elastic strip body, arc elastic lamellar body and the Bian Er formula that is connected as a single entity.
Compared with prior art, the advantage of this punching press spring sheet is: 1, design is more reasonable, is convenient to assembly and disassembly, and cost is low; 2, stamping part its be applicable to large batch of production, manufacturing efficiency is high and meet the production requirement of enterprise; 3, good stability and long service life.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model provides.
In figure, elastomer 1, the first elastic strip body 11, teeth 11a, teeth groove 11b, the second elastic strip body 12, breach 12a, arc elastic lamellar body 13, waist hole 13a, limit ear 14, positioning hole 14a.
Embodiment
As shown in Figure 1, this punching press spring sheet comprises by an elastic plate suppresses the elastomer 1 forming, optimized project, the elastomer 1 of the present embodiment comprises and is splayed shape and symmetrically arranged the first elastic strip body 11 and the second elastic strip body 12, between the first described elastic strip body 11 and the second elastic strip body 12, be connected by the arc elastic lamellar body 13 that is arch, there is waist hole 13a at arc elastic lamellar body 13 middle parts, have respectively to the limit ear 14 of arc elastic lamellar body 13 protrusion direction turnovers away from the both sides, one end of arc elastic lamellar body 13 at the first elastic strip body 11, described limit ear 14 is parallel to each other and is all vertical with the first elastic strip body 11, the shaft axis that has positioning hole 14a and this positioning hole 14a on each limit ear 14 overlaps, there is breach 12a at the second elastic strip body 12 away from one end of arc elastic lamellar body 13, between the some teeth 11a that are also provided with in the one end away from arc elastic lamellar body 13 and two adjacent teeth 11a, form teeth groove 11b on the first elastic strip body 11.
