Description

TECHNICAL FIELD

[0002] The importance of lead-acid battery lead alloy composition testing mainly reflects in the following aspects: by detecting the composition of lead alloy, the quality of alloy material can be ensured to meet relevant standards and design requirements, thereby improving the overall quality of products. Detecting the composition of lead alloy can help understand the performance characteristics of alloy materials and provide data support for the research and development of new materials and new technologies. On the other hand, many countries and regions have strict regulations on the use of lead alloy materials, and testing is one of the important means to ensure product compliance. For example, the lead industry has clear regulations on the content of harmful elements in lead ingot to ensure product quality and environmental protection requirements,

[0003] Currently, lead alloy mainly detects the content of main elements such as lead and other alloy elements such as tin, antimony and copper in the alloy. Direct reading spectrometry is usually used, and the specific requirements for lead alloy direct reading spectrometer samples include the following points: 1. Sample surface is flat: the sample surface must be flat to completely cover the excitation aperture to ensure the stability and accuracy of the excitation process; 2. Sample surface has no defects: the sample cannot have defects such as sand eyes, small holes and segregation to avoid affecting the accuracy of the analysis results; 3. Sample surface is clean and free of contamination: the sample surface must be clean and free of contamination to prevent external substances from affecting the analysis results. Through the above steps and requirements, accurate analysis of lead alloy using direct reading spectrometer can be ensured.

[0004] However, when dissecting and analyzing the composition of the grid alloy in the battery, the lead alloy sample usually only has the size of the lug for use. Due to the small size of the sample, it cannot completely cover the excitation aperture of the direct reading spectrometer, and an iron hammer is usually used to knock the lug to expand its area, but there are defects such as uneven surface and small holes, which affect the accuracy of the analysis results.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will briefly introduce the drawings needed to be used in the embodiment description, and obviously, the drawings in the following description are only some embodiments of the present application, and all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0027] The present application will be further described in detail below in combination with the drawings.

[0028] As Figure 1As shown, the utility model discloses a high density alloy steel plate 12 and extruding device, extruding device is used to drive the sample 11 of being made to sample vertical lifting, reciprocating extrusion to high density alloy steel plate 12, completes the sample of sample preparation, extruding device includes hand pressure lever 1, big piston cylinder, small piston cylinder and hydraulic oil tank 5, big piston cylinder is by big cylinder body 10 and the big piston rod 9 of being installed in big cylinder body 10, and small piston cylinder is by small cylinder body 2 and the small piston rod 3 of being installed in small cylinder body 2, and the cross-sectional area ratio of big cylinder body 10 of big piston cylinder and small cylinder body 2 of small piston cylinder is 1:10-1:50.

[0029] High density alloy steel plate 12 adopts high hardness tool steel, and the working surface of the lower end of high density alloy steel plate 12 is plated with a wear-reducing layer, the wear-reducing layer is titanium nitride, and the working surface of the lower end of high density alloy steel plate 12 is polished to a surface roughness Ra≤0.4μm.

[0030] In use, when preparing a small and irregular lead alloy sample for direct-reading spectrometer, the sample 11 to be prepared is placed on the placement platform of the large piston 9. When the hand pressure lever 1 is lifted upward by hand, the small piston 3 is driven to rise, and thus the volume of the rodless cavity of the small cylinder 2 is increased, and the atmospheric pressure in the cavity is reduced. At this time, the steel ball in the one-way valve 8 closes the passage, and the oil in the hydraulic oil tank 5 enters the rodless cavity of the small cylinder along the oil outlet pipe under the action of atmospheric pressure, forming a first oil suction action. Then, the lever 1 is pressed down, the small piston 3 moves downward, the sealed volume of the rodless cavity of the small cylinder 2 is reduced, and the pressure in the cavity is increased. At this time, the one-way valve 6 closes the passage of the oil outlet pipe, and the pressure oil in the lower cavity of the small cylinder pushes the steel ball in the one-way valve 8 to enter the lower cavity of the large cylinder 10, and drives the large piston 9 to lift the sample 11 to be prepared upward by a distance. By repeatedly lifting the pressure lever 1, the sample 11 can be continuously lifted until it contacts the high-density alloy steel plate to achieve the purpose of extruding the lead alloy sample. Since the high-density alloy steel plate has high strength and hardness, it can be used as an extrusion die. The low yield strength and high plasticity of the lead alloy make it easy to flow during extrusion. In addition, lubricating oil can be applied between the high-density alloy steel plate and the sample to reduce friction and make the deformation more uniform. Through the above method, the small and irregular lead alloy can be extruded into a sample with a smooth surface, a larger size, and a direct-reading spectrometer excitation aperture that can be completely covered.
