Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment in the metallurgical industry, in particular to an iron chip pressing column sampling device for a steel mill. Background Art

[0002] In the machining industry, a large amount of iron chips are generated during production processes such as turning, milling, and planing. These iron chips are generally re-smelted by a steel mill. To facilitate storage and transportation, the iron chips are directly cold-pressed into cylindrical pressing columns under high pressure. Before the steelmaking production process, to ensure the quality of the finished steel, it is necessary to detect the quality of the iron chip pressing columns. During the detection, the iron chip pressing columns need to be manually crushed with a hammer for sampling. The labor intensity of the staff during the sampling process is large, time-consuming and laborious, and the work efficiency is low.

[0003] In the Chinese utility model patent with the publication number CN 211726043 U and the name: High-efficiency Iron Chip Shearing and Crushing Machine, a technical solution for crushing bulk metal materials such as iron chips is disclosed. Since the iron chip pressing columns are relatively large in volume, this utility model is not suitable for crushing the iron chip pressing columns.

[0004] In view of this, it is very necessary to develop an iron chip pressing column sampling device for a steel mill laboratory, which uses a mechanical cutting device to sample and crush the cylindrical iron chip pressing columns to reduce the labor intensity of the staff and improve the work efficiency.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] A device for sampling iron filings pressed columns in a steel mill according to the present utility model, as Figure 1 shown, includes a chassis 1, a column pushing mechanism, a chip cutting mechanism, and a blanking mechanism 7; the column pushing mechanism, the chip cutting mechanism, and the blanking mechanism 7 are all installed on the chassis 1. The iron filings pressed column 10 is pushed and fed by the column pushing mechanism to the chip cutting mechanism for cutting. The cut chips fall into the blanking mechanism 7 for screening. The qualified sample chips are discharged through the lower blanking port, and the unqualified sample materials are discharged through the upper blanking port.

[0021] A device for sampling iron filings pressed columns in a steel mill according to the present utility model, the column pushing mechanism includes an electric hydraulic cylinder 2, a left support 3, a right support 4, a pushing disk 5, a slideway 6, a pressing cover 8, and an iron filings pressed column support seat 11. The left support 3 and the right support 4 are installed on the chassis 1. The electric hydraulic cylinder 2 is installed on the left support 3 and the right support 4. The slideway 6 is installed on the chassis 1 using fasteners. The iron filings pressed column support seat 11 is installed on the slideway 6. When sampling, the iron filings pressed column 10 is placed on the iron filings pressed column support seat 11. The lower flange of the pressing cover 8 and the flange on the iron filings pressed column support seat 11 are fastened together using fasteners to clamp the iron filings pressed column 10. Then, the electric hydraulic cylinder 2 is turned on. The top of the hydraulic rod of the electric hydraulic cylinder 2 drives the pushing disk 5 to move, thereby driving the iron filings pressed column support seat 11 to move on the slideway 6 and feeding the iron filings pressed column 10 to the right to the chip cutting mechanism for cutting.

[0022] A device for sampling iron filings pressed columns in a steel mill according to the present utility model, the chip cutting mechanism includes a tool assembly 9 and a motor 12. The motor 12 and its speed reducer are installed on the chassis 1. The tool assembly 9 is installed on the power output shaft of the speed reducer. The tool assembly 9 includes a cutter head 9-1, a tool holder 9-2, a tool 9-3, and a tool fixing bolt 9-4. The tool holder 9-2 is fixed on the cutter head 9-1. The tool 9-3 is installed on the tool holder 9-2 through the tool fixing bolt 9-4. The motor 12 drives the cutter head 9-1 to rotate, thereby driving the tool 9-3 to rotate and cutting the iron filings pressed column 10.

[0023] A device for sampling iron filings pressed columns in a steel mill according to the present utility model. Since the iron filings pressed column 10 is inevitably uneven in density during pressing, and the orientation of the iron filings in the column is disorderly. When encountering iron filings with an orientation along the circumferential direction of the column, it is difficult to cut during cutting. Therefore, a screen in the blanking mechanism is used for screening to remove unqualified materials. In order to screen thoroughly, a vibrator can be provided on the screen 7-3.
