Description
Technical Field
The utility model relates to a sample shears for aluminium foil tensile test.
Background
Aluminum foil is generally thin, and the thickness of the aluminum foil varies from 0.004mm to 0.01mm, and the common specifications include 0.0045mm and 0.0065 mm. When the aluminum foil is subjected to performance detection, a strip-shaped aluminum foil sample is required to be obtained for detection. The preparation of the sample wafer can affect the result of the mechanical property test.
The existing sampling mode is to use a sample punching device to punch and sample, and is relatively original. The existing sample injector comprises a connector and a shearing device, and in the sampling process, because the thickness of a sample wafer is too thin, the sample wafer is easily wrinkled, the sample wafer after the wrinkling is generated, and the tests of the tensile strength and the elongation rate can be influenced. Moreover, after the existing sampler samples, the edge burrs of the sample wafer are more, and the sampling efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing a sample shears for aluminum foil tensile test.
A sample shears for an aluminum foil tensile test comprises a working table and a pressing knife matched with the working table; the worktable surface is provided with a cutter groove matched with the pressing cutter, the cross section of the cutter groove is trapezoidal, and the width of the cutter groove is gradually increased from the top to the bottom; the tail part of the pressing knife is connected with the working table surface through a rotating shaft, the head part of the pressing knife is connected with the handle, and the middle part of the pressing knife protrudes downwards to form an arc shape; the bottom of the working table surface is provided with a plurality of supporting feet. The bottom of the cutter groove is provided with a plurality of supporting shafts, and the supporting shafts are used for being connected with a working table surface.
Preferably, the arm brace is an adjustable arm brace, and the bottom of the arm brace is connected with the main body part of the arm brace through a bolt. The aluminum foil is thin, so that the levelness requirement of the working table top needs to be guaranteed during shearing.
Preferably, the surface of the handle is provided with a groove matched with a human hand.
Preferably, the handle is made of solid wood.
Preferably, the width of the top of the cutter groove is 15mm, and the width of the bottom of the cutter groove is 15.5 mm.
Preferably, the material of the knife groove is steel.
Has the advantages that:
1. adopt trapezoidal sword groove design in this device, when cuting, can the edge production burr of aluminium foil or by the damage, and be trapezoidal sword groove design, can make things convenient for getting of later stage aluminium foil to take.
2. The knife edge in the device adopts a downward arc-shaped convex design, so that the shearing is convenient, and the generation of wrinkles can be reduced during shearing, thereby ensuring the accuracy of mechanical property detection.
