Abstract
The utility model belongs to the technical field of powder metallurgical manufacturing and particularly relates to a density measuring device for a powder metallurgical product, which adopts the technical scheme that the density measuring device comprises an electronic balance, a water container with an opening at the upper end and a bracket, wherein a cross bar of the bracket corresponds to the upper part of the water container; the water container is arranged on the electronic balance; and a string is arranged on the cross bar of the bracket. The device has the advantages that the design is simple, the measurement is convenient, the measuring speed is improved, and the time is saved.
Description
Technical field
The utility model belongs to powder metallurgy manufacturing technology field, relates in particular to a kind of sintered metal product density measuring equipment.
Background technology
Powder metallurgy is to produce metal powder (adding or do not add non-metal powder), implement to be shaped and sintering, make the job operation of material or goods, powder metallurgy has unique chemical and forms and machinery, physical property, and these performances are can't obtain with traditional casting method, and the utilization PM technique can directly be made porous, half fine and close or full dense material and goods.In the research and production of powder metallurgy, nearly all to understand and measure the density of material, because the mensuration of density is one of main means of control sintered article quality, for the shape of product comparison rule, the available direct method of measurement, promptly use the quality of this object of analytical balance weighing, measure product size, calculate volume again with slide calliper rule, the merchant of gained is the apparent density of this sintered article, but speed is slower when bulk density; When shape of product is complicated, volume is difficult for calculating and tries to achieve the also difficult mensuration of density.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of sintered metal product density measuring equipment is provided.This apparatus structure is simple, adopts the method for measuring in liquid medium, and density measure is convenient, and measuring speed is fast, and the result is accurate.
For solving the problems of the technologies described above, the technical solution of the utility model is: the sintered metal product density measuring equipment, this device comprises water container, the support of electronic balance, upper end open, the cross bar of described support is corresponding with water container top, water container is positioned on the electronic balance, and a cord is arranged on the rack cross-bar.
Cord described in the utility model is a thin copper wire.
When actual density is measured, tested goods are used earlier scales/electronic balance weighing in air, hitch with cord then and put into water container, the length of cord makes tested goods be in suspended state in water, obtain placing the weight that increases before and after the tested goods from the electronic balance reading,, be the weight that tested goods arrange water according to Archimedes' principle, the volume of tested goods just can calculate the density of tested goods fast from density formula.
The beneficial effects of the utility model are: the sintered metal product density measuring equipment, this device comprises water container, the support of electronic balance, upper end open, the cross bar of described support is corresponding with water container top, and water container is positioned on the electronic balance, and a cord is arranged on the rack cross-bar.The method that employing is measured in liquid medium, according to Archimedes' principle, this installs simplicity of design, and it is convenient to measure, and has improved measuring speed, has saved the time.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Among the figure: 1-cross bar, 2-cord, 3-water container, 4-support, 5-electronic balance.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Embodiment
According to shown in Figure 1, the sintered metal product density measuring equipment, this device comprises water container 3, the support 4 of electronic balance 5, upper end open, the cross bar 1 of described support 4 is corresponding with water container 3 tops, water container 3 is positioned on the electronic balance 5, one cord 2 is arranged, these cord 2 these thin copper wires on the rack cross-bar 1.
