Description
Technical field
The utility model belongs to test detecting equipment field, is specifically related to a kind of sample for measuring semi-rigid PVC bar drawing performance and prepares servicing unit.
Background technology
In the Erichsen test carrying out PVC bar, sample to be made the thick flaky material of 4mm ± 0.2mm, and then flaky material dumbbell pattern cutter is cut into dumbbell shape, and PVC sheet surface is straight and even, thickness is wanted evenly, so that the pulling strengrth of Accurate Determining PVC material and tensile strain.The method that previously we had adopted draws two lines with bow pen in PVC bar cross section, PVC bar cross section is divided into three parts and the center section i.e. distance of two lines is about 10mm, then along cross section, two line paper knives are rived PVC bar and are divided into three parts, take the part between middle two lines, and then this part carries out the sheet material that grinder buffing becomes thickness 4mm ± 0.2mm centre, then be cut into dumbbell pattern cutter the dumbbell shape meeting specification.Sample carries out PVC material Erichsen test after constant temperature and humidity status adjustment.This process is loaded down with trivial details, wayward, and paper knife will cut at twice, and the used time is very long, and the surface irregularity cut is whole, and thickness is extremely uneven, is not easy to the thickness controlling material.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and servicing unit prepared by a kind of sample provided, when it can solve and by existing manner PVC bar be made flaky material, the flaky material surface irregularity of existence, the problem that in uneven thickness and cutting process is loaded down with trivial details.
The object of utility model is achieved in that
Servicing unit prepared by a kind of sample for measuring semi-rigid PVC bar drawing performance, it comprises base, base is provided with cutter, cutter comprise double-edged blade and handle of a knife, cutter are that rotary type is connected at connecting portion and base, and base is provided with two mutual bar-shaped troughs arranged side by side, and cutter can insert in bar-shaped trough after turning to bottom, be provided with clip at the two ends of base, fixed band is connected with clip by the coupler body at fixed band two ends.
Concrete, cutter are provided with fixed orifice at connecting portion, base is provided with perforation, the perforation on the fixed orifice of cutter and base is placed on same level position, register pin is inserted perforation and cutter can be made to form rotary type at connecting portion and base be connected with in fixed orifice.
Preferably, the upper surface of base is strip and the xsect of upper surface is arc-shaped concave.
Described base comprises the top panel of arcuate structure and is located at the facade plate of top panel down either side straight down.
The width of described bar-shaped trough cell body is 3mm, and the distance between inside two bar-shaped troughs is 4mm, and the distance on cutter between two blades is 4.2mm.
Adopt said structure, sample can be tailored into accurately the size meeting code requirement, improve specimen surface flatness and thickness evenness, ensure that measuring accuracy, simplify sample preparation, increase work efficiency;
Adopting the structure that cutter are connected by fixed orifice, perforation on base and detent fit, can be that rotary type is connected on basis and simplifies structure, the ease for use of intensifier well realizing cutter at connecting portion and base;
The upper surface of employing base is strip and upper surface is the structure of arc-shaped concave, and what energy was stable like this is placed in base upper surface by columned PVC bar;
Base is adopted to comprise the top panel of arcuate structure and be located at the structure of facade plate of top panel down either side straight down, can on the basis of good support PVC bar, further simplification device structure, the ease for use of intensifier.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
Servicing unit prepared by sample as shown in Figure 1 for measuring semi-rigid PVC bar drawing performance, it comprises base 1, base 1 is provided with cutter 2, cutter 2 comprise double-edged blade and handle of a knife 3, cutter 2 at connecting portion with base 1 for rotary type is connected, base 1 is provided with two mutual bar-shaped troughs 4 arranged side by side, cutter 2 turn to bottom after can insert in bar-shaped trough 4, be provided with clip 5 at the two ends of base 1, fixed band 6 is connected with clip 5 by the coupler body at fixed band two ends.
Described cutter 2 are provided with fixed orifice at connecting portion, base is provided with perforation, perforation on the fixed orifice of cutter and base is placed on same level position, register pin is inserted perforation and cutter 2 can be made to form rotary type at connecting portion with base 1 be connected with in fixed orifice
The upper surface of described base 1 is strip and the xsect of upper surface is arc-shaped concave.
Described base 1 comprises the top panel 8 of arcuate structure and is located at the facade plate 7 of top panel 8 down either side straight down.
The width of described bar-shaped trough 4 cell body is 3mm, and the distance between inside two bar-shaped troughs 4 is 4mm, and the distance on cutter between two blades is 4.2mm.
Adopt said structure, during use, first a PVC bar sample is intercepted, this PVC bar sample is placed on base, with the clip 5 that fixed band 6 connects on base, PVC bar sample is fixed on base arc top surface, then two double-edged blade is lifted centre position, rear aligning PVC bar cross section to cut, in the process of cutting, when incision knife length is inadequate, can move along the length direction of PVC bar, enough sample used is tested until cut, if PVC bar sample is long, also can be divided into two-section to cut, but ensure often to cut the length that length is greater than sample dumbbell shape, PVC bar after incision gets sheet material in device between double-edged blade for cutting dumbbell shape sheet material, the Erichsen test of PVC bar just can be carried out after being cut into dumbbell shape sheet material.
