Description

Technical Field

[0001] This utility model belongs to the field of metal ingot sampling technology, specifically, it relates to a lead ingot ear-shaped sampling device. Background Technology

[0002] Currently, lead ingot sampling often involves taking samples from the molten state during production or from fragments found in the ingot's holes. Oxygen cutting of the ingot's "ear" is also used for sampling. According to Part 16 of the national standard "Chemical Analysis Methods for Lead and Lead Alloys" (GB / T4103), when determining the content of copper, silver, bismuth, arsenic, antimony, tin, and zinc using direct-reading photoelectric emission spectrometry, the sample needs to be machined into a cylindrical shape on a lathe. If the sample is irregular or consists of fragments, it must first be melted and poured into a mold, then machined on a lathe to form a smooth cylinder before direct measurement using photoelectric emission spectrometry can be performed. This undoubtedly increases the sample testing process and cost. Summary of the Invention

[0003] To overcome the problems existing in the background technology, this utility model provides a lead ingot ear-shaped sampling device, which can directly take cylindrical samples from the ear of the lead ingot product without damaging the outer packaging of the product or the appearance and quality of the lead ingot itself. When determining the content of copper, silver, bismuth, arsenic, antimony, tin and zinc by photoelectric direct-reading emission spectroscopy, it can be detected by simple turning, reducing the turning time on the lathe before measurement on the machine (photoelectric direct-reading emission spectrometer), reducing the probability of lead ingot damage and rework costs, shortening the detection time and improving the efficiency of lead ingot detection.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] The lead ingot ear-shaped sampling device includes a pressing machine; the pressing machine includes a top plate, a sliding plate assembly, a bottom plate, a hollow sampling cylinder, a slide rail rod, a spring rod, and a hydraulic rod; the slide rail rod is vertically connected between the top plate and the bottom plate, the sliding plate assembly is disposed between the top plate and the bottom plate, and is slidably connected to the slide rail rod; the spring rod is connected between the sliding plate assembly and the top plate; the hollow sampling cylinder is fixed below the sliding plate assembly, and the hydraulic rod is vertically downward disposed on the lower end face of the top plate.

[0006] Preferably, the sliding plate assembly includes an upper sliding plate, a lower sliding plate, and a positioning post; the positioning post is fixedly connected between the upper sliding plate and the lower sliding plate, the hollow sampling cylinder is fixed to the lower end face of the lower sliding plate, and the lower sliding plate has a through hole that communicates with the hollow sampling cylinder.

[0007] Preferably, the hydraulic rod is coaxial with the hollow sampling cylinder.

[0008] Preferably, a rear servo cylinder is provided between the upper and lower sliding plates; the telescopic rod of the rear servo cylinder is fixed downward on the lower end face of the upper sliding plate; the telescopic rod of the rear servo cylinder is coaxial with the hollow sampling cylinder.

[0009] Preferably, the top of the telescopic rod of the rear-mounted servo electric cylinder is provided with a sample discharge cone, which is threadedly connected to the telescopic rod; the outer diameter of the sample discharge cone is smaller than the inner diameter of the hollow sampling cylinder.

[0010] Preferably, the bottom end of the hollow sampling cylinder is a blade-shaped structure with an inner straight edge and an outer oblique edge.

[0011] The beneficial effects of this utility model are:

[0012] This invention allows for the direct collection of cylindrical samples from the ear of a lead ingot product without damaging the product packaging or the appearance and quality of the lead ingot itself. This reduces damage to the lead ingot caused by sampling. Furthermore, when determining the content of copper, silver, bismuth, arsenic, antimony, tin, and zinc using photoelectric direct-reading emission spectrometry, the sample can be easily machined for testing, reducing the machining time on the lathe before testing on the machine (photoelectric direct-reading emission spectrometer). This reduces the probability of lead ingot damage and rework costs, shortens the testing time, and improves the efficiency of lead ingot testing.

[0013] Typically, a single lead ingot weighs 48kg ± 3kg. Assuming 700 production batches per year, and one ingot is damaged during sampling from each batch, the annual weight of damaged lead ingots would be: 48 * 700 / 1000 = 33.6 tons. Currently, the market price of lead ingots is 16,000 yuan / ton, resulting in a direct loss of 33.6 * 16,000 = 537,600 yuan in output value. The annual loss from sampling lead ingots would be 537,600 yuan. Using this novel sampling method can effectively prevent lead ingot damage. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] In the description of this utility model, unless otherwise stated, the terms "upper" and "lower" indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0020] like Figure 1-2 As shown, the lead ingot ear-shaped sampling device includes a pressing machine 20, which includes a top plate 1, an upper sliding plate 2, a lower sliding plate 3, a bottom plate 4, a positioning column 5, a hollow sampling cylinder 6, a slide rail rod 8, a spring rod 9, and a hydraulic rod 10.

[0021] The slide rail 8 is fixedly connected between the top plate 1 and the bottom plate 4. The upper slide plate 2 and the lower slide plate 3 are slidably connected to the slide rail 8. The positioning post 5 is vertically connected between the upper slide plate 2 and the lower slide plate 3. The upper slide plate 2 and the lower slide plate 3 slide along the slide rail 2 between the top plate 1 and the bottom plate 4 under the extension and retraction of the hydraulic rod 10. The piston rod of the hydraulic rod 10 is fixed vertically downwards to the lower end face of the top plate 1. The spring rod 9 is connected between the top plate 1 and the upper slide plate 2; the spring rod 9 is a retractable rigid spring. The hollow sampling cylinder 6 is fixed to the lower end face of the lower slide rod 3, and a through hole is provided on the lower slide plate 3 directly opposite the hollow sampling cylinder 6.

[0022] When sampling is required, the telescopic rod of the hydraulic rod 10 presses down on the upper sliding plate 2, causing the hollow sampling cylinder 6 to be inserted into the lead ingot 12 for sampling. Simultaneously, the spring rod 9 is stretched as the hydraulic rod 10 presses down. After sampling is completed, the telescopic rod of the hydraulic rod 10 retracts, and the spring rod 9 pulls up the upper sliding plate 2, removing the hollow sampling cylinder 6 from the lead ingot 12, thus completing the sampling. After sampling, the hollow sampling cylinder 6 can be removed by tapping or other means.

[0023] As a preferred option, the bottom end of the hollow sampling cylinder 6 is a blade-shaped structure with an inner straight edge and an outer oblique edge, which can reduce sampling resistance.

[0024] As a preferred embodiment, the hydraulic rod 10 is coaxial with the hollow sampling cylinder 6. This facilitates the vertical insertion of the hollow sampling cylinder 6 into the lead ingot, making it easier to extract well-shaped cylindrical samples and reducing damage to the lead ingot. Furthermore, the entire device is less prone to tilting during sampling, resulting in relatively stable force distribution, which helps reduce the failure rate and extend the service life of this invention.

[0025] The hydraulic rod 10 used in this invention can be any mechanical structure with linear telescopic function. In this embodiment, the hydraulic rod 10 is equipped with a hydraulic oil station 13.

[0026] Demonstration of the use of this utility model:

[0027] The pressing and sampling machine 20 of this invention is set on one side of the lead ingot production line, concentric with the transverse center line of the lead ingot, and maintains a certain safe distance from the lead ingot to avoid affecting its conveying. When the lead ingot is conveyed by the conveyor belt 14, the control system 15 controls the lead ingot ear sample to be directly below the pressing and sampling machine 20 and then stops, and the hydraulic rod 10 presses down to take the sample. Example 2

[0028] This embodiment adds a sample unloading device to the existing embodiment 1. This embodiment mainly describes the sample unloading device, as follows:

[0029] A rear servo electric cylinder 11 is set between the upper slide plate 2 and the lower slide plate 3. The telescopic rod of the rear servo electric cylinder 11 is fixed vertically downward to the lower end face of the upper slide plate 2. A sample outlet cone 7 connected by bolts is set at the bottom end of the telescopic rod of the rear servo electric cylinder 11. The outer diameter of the sample outlet cone 7 is smaller than the inner diameter of the hollow sampling cylinder 6.

[0030] Because the hollow sampling cylinder 6 experiences significant friction when removing the lead ingot sample after sampling, making it difficult to remove, a rear-mounted servo cylinder 11 enables mechanical sample removal. After sampling, operating the rear-mounted servo cylinder 11 extends its telescopic rod, ejecting the lead ingot sample from the hollow sampling cylinder 6. A bolted sample ejection cone 7 at the bottom of the telescopic rod of the rear-mounted servo cylinder 11 facilitates replacement if damaged.

[0031] The sampling method of this invention will not damage the shape and size of the lead ingot or cause damage to the lead ingot during sampling. It can also quickly obtain a suitable cylindrical sample, improve sampling efficiency, and reduce the time and cost of machining block materials on a lathe.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
