Description

Technical Field

[0001] The present application relates to the technical field of steel bar tensile testing, and in particular to a steel bar tensile testing machine with a dust removal device. Background Art

[0002] The steel bar tensile testing machine is a device mainly used to test the tensile properties and mechanical indicators of steel bars. It adopts hydraulic transmission and control system to measure the tensile strength, yield strength, elongation and other parameters by stretching the steel bars. It is widely used in construction engineering, bridge engineering, road engineering and other fields, providing reliable guarantee for engineering quality.

[0003] A steel bar tensile testing machine mentioned in an existing Chinese public patent (authorization announcement number: CN211085959U) relates to a steel bar tensile testing machine, which solves the problem that the existing steel bar tensile testing machine needs to repeatedly install an extensometer when testing the next steel bar, which is very troublesome and has safety hazards. It includes a machine body, an extensometer is provided on the machine body, a horizontal plate is horizontally provided on the machine body, a vertical plate is slidably connected to the horizontal plate along the length direction of the horizontal plate, the extensometer is provided on the vertical plate, and a driving component for driving the vertical plate to slide is provided on the horizontal plate. The utility model has the effect of not needing to remove the extensometer when replacing the test steel bar, thereby facilitating the operation of the operator and avoiding safety hazards.

[0004] When the steel bar tensile testing machine is in use, it is used to detect the steel bars. The steel bars are stretched until they break through the testing machine, and steel bars of different lengths, diameters or materials are tested, and the test data are tested.

The present application provides a steel bar tensile testing machine with a dust removal device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0022] By adopting the above technical solution, the second moving block slides on the limiting column to limit the mounting plate.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When the steel bar tensile testing machine is stretching, start the motor, and the motor rotation drives the fan blades to rotate to generate suction. The suction enters the trumpet tube from the connecting pipe to inhale the metal dust generated when the steel bar is stretched. The inhaled metal dust then enters the connecting pipe from the trumpet tube and then enters the bellows. When the metal dust passes through the filter, it is blocked and filtered by the filter. The air is discharged from the exhaust pipe. The metal dust blocked and filtered by the filter falls from the filter into the collection box. The metal dust generated when the steel bar is broken is inhaled and collected through the dust suction mechanism, which reduces the dispersion of metal dust and reduces the inhalation and skin contamination of nearby workers, making it easier to use the testing machine.

[0025] 2. When the position of the bell mouth needs to be adjusted, start the motor, and the motor drives the screw to rotate, so that the moving block 1 moves on the screw, driving the mounting plate to move on the cabinet. During movement, the moving block 2 slides on the limiting column to limit the mounting plate, so that the bellows drives the bellows to move to adapt to the inhalation of metal dust when steel bars of different lengths are stretched, so that the bellows is in a suitable position to facilitate the inhalation of metal dust.

[0035] When the steel bar tensile testing machine is in use, the staff will put the steel bar to be tested between the upper clamp 6 and the lower clamp 7. The upper clamp 6 and the lower clamp 7 will fix the steel bar, and then move the hydraulic telescopic rod 1 2 and the hydraulic telescopic rod 2 3 to make the upper clamp 6 and the lower clamp 7 relatively far apart, and stretch the steel bar until it breaks. During the stretching, the metal dust generated when the steel bar is broken is sucked in and collected through the dust suction mechanism, so as to reduce the dispersion of metal dust and the inhalation and skin contamination of nearby staff, thereby facilitating the use of the testing machine.

[0036] Reference Figure 2 and Figure 3 The dust collection mechanism includes a bellows 9 fixed to the side of the mounting plate 8, a connecting pipe 10 is fixed on one end of the bellows 9, a trumpet 11 is fixed on the end of the connecting pipe 10 away from the bellows 9, and the trumpet 11 corresponds to both the upper clamp 6 and the lower clamp 7. An exhaust pipe 12 is fixed on the end of the bellows 9 away from the connecting pipe 10, and a dust collection component is arranged between the connecting pipe 10 and the bellows 9. The dust collection component includes a motor 13 fixed in the bellows 9, a fan blade 14 is fixed to the output end of the motor 13 and is distributed in an array, the fan blade 14 corresponds to the connecting pipe 10, and a collecting piece is arranged between the fan blade 14 and the connecting pipe 10. The collecting piece includes a filter screen 15 arranged in the bellows 9, the filter screen 15 is located on the side of the fan blade 14 away from the motor 13, a collecting box 16 is fixed on the side of the filter screen 15, and the collecting box 16 is located between the filter screen 15 and the connecting pipe 10. One end of the filter screen 15 and the collection box 16 both extend out of the bellows 9, and the filter screen 15 and the collection box 16 are both slidably arranged with the bellows 9. A rotating column 17 is fixed to the side of the bellows 9, and a spring 18 is rotatably connected to the rotating column 17. A limiting groove is fixed to one end of the spring 18 corresponding to the collection box 16, and the spring 18 is located in the limiting groove.

[0037] When the steel bar tensile testing machine is in use, the motor 13 is started, and the rotation of the motor 13 drives the fan blade 14 to rotate and generate suction. The suction enters the bellows 11 from the connecting pipe 10 to suck in the metal dust generated when the steel bar is stretched. The sucked metal dust then enters the connecting pipe 10 from the bellows 11 and then enters the bellows 9. When the metal dust passes through the filter 15, it is blocked and filtered by the filter 15. The air is discharged from the exhaust pipe 12. The metal dust blocked and filtered by the filter 15 falls from the filter 15 into the collection box 16, which is convenient for cleaning and collecting the metal dust. When the collection box 16 and the filter 15 need to be cleaned, First, close the hydraulic telescopic rod 2 to stop the test, then pull the spring piece 18 to make the elastic force disengage from the limiting groove, and then rotate the spring piece 18 on the rotating column 17 to release the resistance to the collection box 16, and then pull the collection box 16 and the filter 15 out of the bellows 9, so that the workers can clean or replace the collection box 16 and the filter 15, replace them with new ones, and then reset the spring piece 18, which is convenient for the workers to disassemble. Through the dust suction mechanism, the metal dust generated when the steel bar is broken is sucked in and collected, reducing the dispersion of metal dust and reducing the inhalation of nearby workers and contamination of their skin, which is convenient for the use of the testing machine.

[0038] Reference Figure 4 A fixing plate 19 is fixed to the side of the cabinet 1, a motor 20 is fixed to the side of the fixing plate 19, an output end of the motor 20 penetrates the fixing plate 19 and is fixedly connected to a screw rod 21, a moving block 22 is threadedly connected to the screw rod 21, and the moving block 22 is fixedly connected to the mounting plate 8 at one end away from the screw rod 21, and a limiting component is provided at one end of the mounting plate 8 away from the screw rod 21. The limiting component includes a fixing plate 23 fixed to the cabinet 1, a limiting column 24 is fixed to the fixing plate 23, a moving block 25 is fixed to one end of the mounting plate 8 away from the moving block 22, and the limiting column 24 slides through the moving block 25.

[0039] When the steel bar tensile testing machine is in use, when the position of the bell mouth needs to be adjusted, the motor 20 is started, and the motor 20 drives the screw 21 to rotate, so that the moving block 1 22 moves on the screw 21, and drives the mounting plate 8 to move on the cabinet 1. During the movement, the moving block 25 slides on the limiting column 24 to limit the mounting plate 8, so that the bellows 9 drives the bell tube 11 to move, so as to adapt to the inhalation of metal dust when steel bars of different lengths are stretched, so that the bell tube 11 is in a suitable position to facilitate the inhalation of metal dust.

[0040] The implementation principle of the steel bar tensile testing machine with a dust removal device in this embodiment is as follows: when the steel bar tensile testing machine is used, the staff puts the steel bar to be tested between the upper clamp 6 and the lower clamp 7, the upper clamp 6 and the lower clamp 7 fix the steel bar, and then the upper clamp 6 and the lower clamp 7 are moved away from each other by the movement of the hydraulic telescopic rod 1 2 and the hydraulic telescopic rod 2 3, and the steel bar is stretched until it breaks;

[0041] When the steel bar tensile testing machine is stretched, the motor 13 is started, and the rotation of the motor 13 drives the fan blade 14 to rotate to generate suction. The suction enters the bellows 11 from the connecting pipe 10 to suck in the metal dust generated when the steel bar is stretched. The sucked metal dust then enters the connecting pipe 10 from the bellows 11 and then enters the bellows 9. When the metal dust passes through the filter 15, it is blocked and filtered by the filter 15. The air is discharged from the exhaust pipe 12, and the metal dust blocked and filtered by the filter 15 falls from the filter 15 into the collection box. 16, it is convenient to clean and collect metal dust. When it is necessary to clean the collection box 16 and the filter screen 15, first close the hydraulic telescopic rod 12, stop the test, then pull the spring piece 18 to make the elastic force disengage from the limiting groove, and then rotate the spring piece 18 on the rotating column 17 to release the resistance to the collection box 16, and then pull the collection box 16 and the filter screen 15 out of the bellows 9, replace them with new ones, and then reset the spring piece 18, which is convenient for the staff to disassemble and clean or replace the collection box 16 and the filter screen 15;

[0042] When the position of the bell mouth needs to be adjusted, the motor 20 is started, and the motor 20 drives the screw 21 to rotate, so that the moving block 1 22 moves on the screw 21, and drives the mounting plate 8 to move on the cabinet 1. During the movement, the moving block 25 slides on the limiting column 24 to limit the mounting plate 8, so that the bellows 9 drives the bellows 11 to move, so as to adapt to the inhalation of metal dust when the steel bars of different lengths are stretched, so that the bellows 11 is in a suitable position to facilitate the inhalation of metal dust.
