According to the shearing mold, shearing operation of the rod-like sample can be conveniently implemented, the sheared sample particles are uniform, the shearing efficiency of the rod-like sample is increased, the labor intensity is reduced, and the sample cost is saved.
Description
Technical field
The utility model relates to a kind of shearing die that is used for the bar-shaped sample of iron and steel gas analysis.
Background technology
Usually smelter is measured through laboratory analytical instrument gases such as oxygen, nitrogen, hydrogen in the iron and steel, and its sample that adopts is generally bar-shaped sample, and bar-shaped sample is delivered to analytical instrument enforcement gas analysis detection after cutting into graininess through shearer; According to the gas analysis requirement; The weight of graininess sample need be controlled within the specific limits; If weight is overweight or kick the beam, all can cause oxygen, nitrogen, hydrogen assay value in the iron and steel unstable, so the Weight control of graininess sample is a very important prerequisite that obtains accurate assay value.
At present because the sample presentation mouth of shearer has certain distance with the shearing edge of a knife; And over head and ears in the shearer, the operator can't see the sheared length of bar-shaped sample to shear knife outside, and the sample presentation mouth does not have any sample introduction indication; So can only be when shearing sample by range estimation decision sample presentation length; The while hand also need be held bar-shaped sample and send toward the sample presentation oral instructions gradually, because shearer sample presentation mouth is bigger, upwarps owing to shearing force down causes bar-shaped sample during shearing; So hand need follow sample to upwarp during sample presentation, brings very big influence to shearing.This shear history can't be held owing to sample introduction length, and is short or long, causes the sample grain size of shearing to differ, and then sample weight differs greatly.For satisfying the weight requirement of sample, generally all need select the close sample of size then and come both to lose time, waste sample like this through repeatedly shearing times without number as analytical sample, increased labour intensity again, prolonged analytical cycle.
Summary of the invention
The utility model technical matters to be solved provides a kind of shearing die that is used for the bar-shaped sample of iron and steel gas analysis; Utilize this shearing die can conveniently implement the shearing operation of bar-shaped sample; And the sample uniform particles that cuts into; Improve the shear efficiency of bar-shaped sample, reduced labour intensity, practiced thrift the sample cost.
For solving the problems of the technologies described above; The shearing die that the utility model is used for the bar-shaped sample of iron and steel gas analysis comprises ring flange, bottom plate, goes up locating piece and scale; Said ring flange center is provided with the through hole with bar-shaped specimen finish coupling; Said bottom plate and last locating piece are located at the both sides of said ring flange respectively, and the end face level of said bottom plate is provided with the elongated slot that the cross section is an arc, and the said bottom surface level that goes up locating piece is provided with the elongated slot that the cross section is a U-shaped; Said bottom plate end face elongated slot is consistent with the axis of said ring flange central through hole with the axis of last locating piece bottom surface elongated slot, and said scale is located at said bottom plate end face and is positioned at a side of bottom plate elongated slot.
Because being used for the shearing die of the bar-shaped sample of iron and steel gas analysis, the utility model adopted technique scheme; Be that this shearing die comprises ring flange, bottom plate, goes up locating piece and scale; The ring flange center is provided with the through hole with bar-shaped specimen finish coupling; Bottom plate and last locating piece are located at the both sides of ring flange respectively, and the end face level of bottom plate is provided with the elongated slot that the cross section is an arc, and the bottom surface level of last locating piece is provided with the elongated slot that the cross section is a U-shaped; Bottom plate end face elongated slot is consistent with the axis of ring flange central through hole with the axis of last locating piece bottom surface elongated slot, and scale is located at the bottom plate end face and is positioned at a side of bottom plate elongated slot.This shearing die can conveniently be implemented the shearing operation of bar-shaped sample, and the sample uniform particles that cuts into, and has improved the shear efficiency of bar-shaped sample, has reduced labour intensity, has practiced thrift the sample cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is the structural representation of the shearing die of the bar-shaped sample that originally is used for the iron and steel gas analysis;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The shearing die that the utility model is used for the bar-shaped sample of iron and steel gas analysis comprises ring flange 1, bottom plate 2, goes up locating piece 3 and scale 4; Said ring flange 1 center is provided with the through hole 11 with bar-shaped specimen finish coupling; Said bottom plate 2 and last locating piece 3 are located at the both sides of said ring flange 1 respectively; The end face level of said bottom plate 2 is provided with the elongated slot 21 that the cross section is an arc; The said bottom surface level that goes up locating piece 3 is provided with the elongated slot 31 that the cross section is a U-shaped, and the axis of said bottom plate 2 end face elongated slots and last locating piece 3 bottom surface elongated slots 31 is consistent with the axis of said ring flange 1 central through hole 11, and said scale 4 is located at said bottom plate 2 end faces and is positioned at a side of bottom plate elongated slot 21.
This shearing die is located at sample presentation mouth one side of shearer through ring flange, and last locating piece stretches in the sample presentation mouth of shearer; When bar-shaped sample is sheared operation; Bar-shaped sample is positioned in the elongated slot of bottom plate, and in the sample presentation mouth of shearer, advances until being sheared into graininess through the ring flange central through hole, in the shear history; Bar-shaped sample receives the spacing of bottom plate arc elongated slot, ring flange central through hole and last locating piece U-shaped elongated slot; Make and avoid upwarping when bar-shaped sample is sheared, improved the stability that sample is sheared, help shearing the particle sample of identical weight; When bar-shaped sample advances in the arc elongated slot of bottom plate simultaneously; Can be according to the indication of the other scale of arc elongated slot; Grasp the length that bar-shaped sample advances, thereby guarantee that the particle sample of shearing has identical length basically, to satisfy the requirement of analytical instrument particle sample weight.
This shearing die is simple in structure, and bar-shaped sample shearing manipulation is convenient, has greatly improved the shear efficiency of sample, has reduced labour intensity, and what is more important has guaranteed the particle sample weight consistency of shearing, for gas analysis in the iron and steel provides accuracy guarantee.
