Abstract
The utility model discloses a silver shearing sword relates to toolmaking technical field, including the blade that is equipped with the cutting edge mouth, the blade all is equipped with in both ends the cutting edge mouth, the blade is in two side between the cutting edge mouth is equipped with a location breach at least, the blade passes through the clamp plate dress on the blade holder, at least, be equipped with on the blade holder one with the locating pin of location breach looks joint. Compare prior art, the utility model discloses can solve the problem that current integral type shear knife life shortens.
Description
Technical field
This utility model is related to cutter manufacture technical field, especially a kind of cutter for the shearing of silver-colored rivet contacts.
Background technology
Silver contact, also known as silver-colored rivet contacts, is widely used in the contact component of appliance switch circuit；Contact component quality is not
Height can affect conductive resistance and lead to product to generate heat, thus affecting use safety and the service life of product.Because silver belongs to expensive
Heavy metal, for cost-effective, existing commonly used compound rivet contacts, includes copper rivet in compound rivet contacts and is located at
The silver layer at this copper rivet top, the thickness of silver layer is 0.2 millimeter -1 millimeter；Its processing method is is using a kind of cold press welder,
By sheaves under shearing on silver band volume silver strip up to specification, then by silver strip be placed in copper rivet top and therewith cold welding be
Silver-colored rivet contacts.Wherein, sheaves are the main tool of silver strip blanking, and presently used sheaves are integral type sheaves,
This integral type shears includes the blade being provided with shearing edge.This integral type sheaves exist in use asks as follows
Topic：Because silver strip is very thin, therefore, using the used time, the anterior wear down of blade just can be operated, and the hardness of wear down blade
All there is decline with wearability, lead to service life to shorten, use cost increases.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of silver part sheaves, to solve existing integral type shearing
The problem that knife service life shortens.
This utility model solves the technical scheme that adopted of technical problem：This silver part sheaves include being provided with shear blade
The blade of mouth, described blade is equipped with described shearing edge, side between two described shearing edges for the described blade in two ends
While at least provided with a locating notch；Described blade is contained on tool rest by pressing plate；At least provided with one and institute on described tool rest
State the alignment pin of locating notch phase clamping.
In above-mentioned silver part sheaves technical scheme, more specifically technical scheme can also be：Described blade is in described in two
Two sides between shearing edge are respectively provided with a corresponding described locating notch respectively；Described tool rest is provided with two points
Described alignment pin not with two described locating notch phase clampings.
Further：Each described locating notch is respectively positioned on the center of place side.
Due to employing technique scheme, this utility model compared with prior art has the advantages that：1st, by
In being thin slice by blade and centering is made two ends and all had shearing edge, when turning around to use after the shearing edge abrasion of one end, carry
The service life of high blade；2nd, the tool rest of this silver-colored part shears and pressing plate are reusable, reduce use cost.

Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail：
Silver-colored part sheaves as shown in Figures 1 to 4 include the blade 5 being provided with shearing edge 5-2, and blade 5 is all provided with two ends
Have shearing edge 5-2, two shearing edge 5-2 to be symmetrical set, the blade 5 of the present embodiment in two shearing edge 5-2 it
Between two sides be respectively provided with a corresponding locating notch 5-1 respectively, each locating notch 5-1 is respectively positioned in side
At the heart 1, two locating notch 5-1 are mutually corresponding；Two sides between two shearing edge 5-2 for the blade 5 also respectively have
Two bolt installation gaps；Blade 5 passes through pressing plate 4 and four bolts 2 are contained on tool rest 1；The present embodiment is on tool rest 1 equipped with two
The individual alignment pin 3 with two locating notch 5-1 phase clampings respectively.
Claims (3)
