Description

Technical Field

[0001] This utility model relates to the field of high manganese steel shot testing, and more specifically, to a hardness testing and fixing device for high manganese steel shot. Background Technology

[0002] Steel shot is a type of spherical particle made from special materials through a special heat treatment process. First, high-quality steel blocks, filaments, and steel chips are melted. Then, using a centrifugal disc, the molten steel is centrifuged at high speed and thrown into water, causing the surface temperature of the steel shot to drop rapidly, forming the shot – this is the first quenching. After the first quenching, the shot is dried and reheated in a furnace to achieve the desired hardness. The tempered steel shot is then mechanically sorted through sieves into different grades conforming to SAE standards for use in shot peening equipment.

[0003] For example, CN209027907U discloses a fixing device for testing the hardness of ultra-high manganese steel inlaid alloy block hammers. This device includes a base plate with a hammer placement groove located near the center of the top of the base plate. A first side plate and a second side plate are fixedly connected to the left and right sides of the base plate, respectively, and a top plate is fixedly connected to the top of the first and second side plates. This fixing device for testing the hardness of ultra-high manganese steel inlaid alloy block hammers solves the problem of traditional hammers being difficult to fix during hardness testing, which inconveniences users. It allows the hammer to be fixed in place, preventing movement during testing and thus improving practicality.

[0004] As can be seen from the above-mentioned publicly available scheme, the clamping block of the high manganese steel shot is currently fixed. When clamping smaller high manganese steel shot particles, the clamping block is prone to blocking the upper end of the high manganese steel shot. As a result, when the hardness detector is lowered and the high manganese steel shot is hammered, it is easy to collide with the upper end of the clamping block, which affects the detection work and is prone to damage to the hardness detector. At the same time, the high manganese steel shot will be smashed and broken during the detection. The broken fragments are easy to splash and can easily hit the face of the staff, which can easily injure the staff. Utility Model Content

[0005] The purpose of this invention is to provide a hardness testing and fixing device for high manganese steel shot, so as to solve the problem of limiting and protecting high manganese steel shot.

At the same time, the third telescopic rod connects to the ear plates, the ear plates connect to the collar, and the collar connects to the corrugated ring, which facilitates automatic raising and lowering of the corrugated ring. The corrugated ring can also wrap around and shield the upper part of the base, preventing the slag from splashing onto the workers when the high manganese steel shot is crushed.

[0007] Preferably, the through hole is located at the lower end of the groove, and the interior of the groove is connected to the interior of the through hole.

[0008] Preferably, the top plate is disposed inside the groove, and a reinforcing block is fixedly disposed at the lower end of the top plate, the lower end of the reinforcing block being fixedly disposed at the upper end of the first telescopic rod.

[0025] Please see Figure 1-5The diagram shows a hardness testing and fixing device for high manganese steel shot, comprising a base 1 with a groove 2 and multiple through holes 3 at its lower end. A first telescopic rod 4 is fixedly mounted at the lower end of the base 1, and a top plate 5 is fixedly mounted at the upper end of the first telescopic rod 4. Anti-detachment blocks 7 are fixedly mounted on the left and right sides of the top plate 5, and high manganese steel shot 9 is placed on the upper end of the top plate 5. Multiple second telescopic rods 10 are fixedly mounted at the upper end of the base 1, and a clamping block 11 is fixedly mounted at one end of each second telescopic rod 10. The clamping block 11 is equipped with a locking mechanism. The upper end of the slot 12 and the base 1 is fixedly provided with an installation ring 13. The upper end of the installation ring 13 is fixedly provided with a corrugated ring 14. The upper end of the corrugated ring 14 is fixedly provided with a collar 15. The left and right ends of the collar 15 are respectively fixedly provided with ear plates 16. The lower end of the ear plates 16 is fixedly provided with a third telescopic rod 17. The first telescopic rod 4, the second telescopic rod 10 and the third telescopic rod 17 are model YNT-03. The plugs of the first telescopic rod 4, the second telescopic rod 10 and the third telescopic rod 17 are connected to an external power supply, which is the prior art.

[0026] To facilitate the positioning of the high manganese steel shot 9 and the upper end of the protective wrapping base 1, a through hole 3 is set at the lower end of the groove 2, and the interior of the groove 2 is connected to the interior of the through hole 3. The top plate 5 is set inside the groove 2, and a reinforcing block 6 is fixedly set at the lower end of the top plate 5. The lower end of the reinforcing block 6 is fixedly set at the upper end of the first telescopic rod 4. Anti-detachment grooves 8 are respectively set on the left and right sides of the base 1. Anti-detachment blocks 7 are slidably set inside the anti-detachment grooves 8. The lower end of the high manganese steel shot 9 is set at the upper end of the interior of the groove 2. The clamping block 11 is slidably set at the upper end of the base 1. The high manganese steel shot 9 is slidably engaged inside the slot 12. The high manganese steel shot 9 is set inside the corrugated ring 14. The lower end of the third telescopic rod 17 is fixedly set at the upper end of the base 1. The third telescopic rod 17 is set outside the corrugated ring 14.

[0027] In this implementation scheme, the first telescopic rod 4 is connected to the top plate 5, which facilitates the automatic raising and lowering of the top plate 5. The top plate 5 automatically pushes the high manganese steel shot 9 upward, so that the clamping block 11 engages with the high manganese steel shot 9 at a suitable position, preventing the clamping block 11 from obstructing the upper part of the high manganese steel shot 9, thereby avoiding damage to the testing tool during testing.

The corrugated ring 14 wraps around and shields the upper part of the base 1, preventing the slag from splashing onto the workers when the high manganese steel shot 9 is crushed.

[0028] First, activate the first telescopic rod 4. The first telescopic rod 4 moves the top plate 5 upward, and at the same time, the anti-detachment block 7 and the anti-detachment groove 8 slide and engage. When the top plate 5 moves upward to the appropriate position, activate the second telescopic rod 10. The second telescopic rod 10 moves the clamping block 11 to the appropriate position, and then moves the high manganese steel shot 9 into the groove 2, so that the high manganese steel shot 9 engages in the groove 12. Then activate the second telescopic rod 10 again. The second telescopic rod 10 moves the clamping block 11 to move and squeeze the high manganese steel shot 9, thereby limiting and fixing the high manganese steel shot 9 to prevent it from moving. Then activate the third telescopic rod 17, so that the third telescopic rod 17 moves the ear plate 16 upward, and at the same time, the tension collar 15 moves upward, so that the corrugated ring 14 is stretched and moved upward, thereby covering and shielding the upper end of the base 1 through the corrugated ring 14, preventing the high manganese steel shot 9 from splashing and moving during testing and accidentally injuring the staff.
