Description

The novel circlip formed punch that presses

Technical field

The utility model relates to power battery production equipment technologies, and in particular to the novel circlip formed punch that presses.

Background technique

As shown in Figure 1, the circlip punch contact surface in the prior art that presses is single plane (contacting with circlip)；It pressed The conductive process of stress in journey are as follows: circlip --- ceramics --- sealing ring, sealing ring forced contraction, circlip are displaced downwardly in pole card slot Completion presses operation, this operation mode, easily leads to ceramics and ruptures bad generation.It is lower so as to cause production yield and there are qualities Risk, it would be highly desirable to improve.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, and design is closed Reason, the novel circlip formed punch that presses easy to use, it is also ensured that circlip is smooth while capable of greatly reducing ceramic stress It is pressed into pole card slot, to improve the yield and quality of product.

In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes formed punch ontology, No.1 indent, two Number indent, No. three indents；The inside of formed punch body bottom portion successively offers No.1 indent, No. two indents, No. three pressures from top to bottom Slot, and No.1 indent and No. two indents are cylindrical recess, No. three indents are arch groove；The diameter of the No.1 indent is less than The diameter of No. two indents.

After adopting the above structure, the utility model has the beneficial effect that the novel circlip formed punch that presses described in the utility model, It is also ensured that circlip is smoothly pressed into pole card slot, to improve product while ceramic stress can greatly be reduced The advantages that yield and quality, the utility model have structure simple, and setting is reasonable, low manufacture cost.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of circlip formed punch of pressing in the prior art.

Fig. 2 is the structural schematic diagram of the utility model.

Fig. 3 is the cross-sectional view of the utility model.

Fig. 4 is the operation chart of specific embodiment.

Description of symbols:

Formed punch ontology 1, No.1 indent 2, two indent 3, three indent 4, circlip 5.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

Referring to as shown in figs 2-4, present embodiment the technical solution adopted is that: it includes formed punch ontology 1, No.1 The indent 4 of indent 3, three of indent 2, two；The inside of 1 bottom of formed punch ontology successively offers No.1 indent 2, two from top to bottom 3, No. three indents 4 of indent, and No.1 indent 2 and No. two indents 3 are cylindrical recess, No. three indents 4 are arch groove；Formed punch ontology 1 material is using C_r12, hardness HRC55, the diameter D of 1 end cap of formed punch ontology₁It is 5mm, formed punch sheet for 40mm, thickness H The diameter D of 1 lower end of body₂For 30mm, length L₁For 44.7mm；The diameter of the No.1 indent 2 less than No. two indents 3 diameter, The diameter D of No.1 indent 2₃For 17mm, the depth L of No.1 indent 2₂For 8.95mm, the diameter D of No. two indents 3₄For 23.4mm, two The depth L of number indent 3₃For 3.57mm, the basal diameter D of No. three indents 4₅For 26.85mm, the depth L of No. three indents 4₄For 1.85mm。

The working principle of this specific embodiment:: when the utility model is used, product to be pressed is placed on the present apparatus Lower part, the upper end of pole stretches the inside for being located at No.1 indent 2, and the cambered surface of No. three indents 4 contacts setting, No. two indents with aluminium sheet 3 inner top surface contacts setting with circlip 5, and during pressing, compresses seal after aluminium sheet stress, was then only card before this Spring 5 and ceramic stress, sealing ring forced contraction, circlip 5, which is displaced downwardly in pole card slot, completes the operation that presses, in the process, greatly The stress of ceramics is reduced greatly simultaneously it is also ensured that circlip 5 is smoothly pressed into, to improve the yield and quality of product.

After adopting the above structure, present embodiment has the beneficial effect that novel described in present embodiment press Circlip formed punch, it is also ensured that circlip is smoothly pressed into pole card slot, to mention while capable of greatly reducing ceramic stress The high yield and quality of product, the utility model have structure simple, setting rationally, the advantages that low manufacture cost.

The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope should all cover in the scope of the claims of the utility model.
