Description

Technical Field

[0001] This utility model relates to the field of cold-drawn steel testing technology, specifically a hardness testing device for cold-drawn steel production. Background Technology

[0002] There are many types of cold-drawn steel, including cold-drawn round steel, cold-drawn square steel, cold-drawn flat steel, cold-drawn hexagonal steel, and cold-drawn special-shaped steel. During the production and processing of cold-drawn special-shaped steel, a hardness test is required. Currently, this test requires specialized equipment. Workers typically place the cold-drawn special-shaped steel on a testing platform and apply gravity pressure using a hydraulic cylinder. The steel is then inspected under varying degrees of gravity to determine its hardness value.

[0003] When cold-drawn special-shaped steel is inspected on the testing platform, if it is necessary to test the other side of the cold-drawn special-shaped steel, the staff needs to manually flip the cold-drawn special-shaped steel. Sometimes, when the device is out of control, the gravity plate will fall and injure the staff's hands, which is extremely dangerous. Therefore, this utility model proposes a hardness testing device for cold-drawn steel production to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a hardness testing device for cold-drawn steel production, the hardness testing device for cold-drawn steel production includes: a processing table 1, a hardness testing device 2 is provided on the surface of the processing table 1, a second electric push rod 3 is provided on the side of the processing table 1, a lifting plate 4 is provided at the lifting end of the second electric push rod 3, a base plate 5 is provided on the side of the lifting plate 4, a drive motor 6 is provided on the surface of the base plate 5; a rotating rod 7, a first electric push rod 8 is provided at the end face of the rotating rod 7, a limit plate 9 is provided at the telescopic end of the first electric push rod 8, and a cold-drawn steel 10 is placed on the surface of the processing table 1;

[0024] First, place the cold-drawn steel profile 10 on the surface of the processing table 1. Then, activate the first electric push rod 8 to limit the two ends of the cold-drawn steel profile 10 with the limiting plate 9 to prevent deviation during testing. Then, activate the hardness testing device 2 for testing. When it is necessary to test the other side of the cold-drawn steel profile 10, activate the second electric push rod 3 to move the lifting plate 4 upward, thereby moving the cold-drawn steel profile 10 upward. After moving to a suitable height, activate the drive motor 6 to rotate the cold-drawn steel profile 10. Then, reset the lifting plate 4 to place the rotated cold-drawn steel profile 10 on the processing table 1, and then it is convenient to test the other side of the cold-drawn steel profile 10.

[0025] Example 2: Based on Example 1, a limiting plate 9 is provided to facilitate the inspection of the cold-drawn steel 10. The limiting plate 9 is fixedly connected to the telescopic end of the first electric push rod 8. The limiting plate 9 has an overall "L" shaped plate structure. A guide groove 13 is provided on the inner side of the limiting plate 9. A bearing 14 is provided on the surface of the limiting plate 9. A lifting screw 15 is fixedly connected to the inner ring surface of the bearing 14. A traction plate 16 is screwed onto the surface of the lifting screw 15. The traction plate 16 has an overall "L" shaped plate structure. An auxiliary plate 17 is provided at the bottom of the traction plate 16. A guide plate 18 is provided on the side of the auxiliary plate 17 and the traction plate 16. The guide plate 18 is inserted into the guide groove 13 and is slidably connected to the guide groove 13.

[0026] When the cold-drawn steel section 10 is placed on the processing table 1, the first electric push rod 8 can be activated to push the limiting plate 9. This allows the two sets of limiting plates 9 to limit the two ends of the cold-drawn steel section 10, preventing it from shifting during inspection. Then, the lifting screw 15 can be rotated in conjunction with the bearing 14, which in turn drives the auxiliary plate 17 to move, thus facilitating the adaptation to cold-drawn steel sections 10 of different thicknesses. The guide plate 18, in conjunction with the guide groove 13, prevents the auxiliary plate 17 from rotating when the lifting screw 15 is rotated.

[0027] Example 3: Based on Example 2, a drive motor 6 is provided to facilitate the flipping of the cold-drawn steel 10. Two sets of second electric push rods 3 are provided, and the two sets of second electric push rods 3 are symmetrically distributed about the processing table 1. The lifting plate 4 is fixedly connected to the lifting end of the second electric push rod 3. The lifting plate 4 has an overall "L" shaped plate structure. A support plate 11 is provided at the bottom of the lifting plate 4. The drive motor 6 is fixedly connected to the surface of the base plate 5. A through hole is opened on the side of the lifting plate 4. A limit bearing 12 is provided in the through hole. The rotating rod 7 is fixedly connected to the inner ring surface of the limit bearing 12. The transmission end of the drive motor 6 is fixedly connected to the end face of the rotating rod 7.

[0028] When in use, the lifting plate 4 can be moved upward by the second electric push rod 3, and then the rotating rod 7 can be rotated in conjunction with the limit bearing 12, so that the cold-drawn steel 10 can be flipped over, which is convenient for subsequent inspection of the other side of the cold-drawn steel 10. When not in use, the support plate 11 can be used to support the lower part of the lifting plate 4, thereby reducing the pressure on the lifting end of the second electric push rod 3.
