Description

Technical Field

[0001] The utility model relates to the technical field of steel plates, in particular to a composite wear-resistant steel plate. Background Art

[0002] Wear-resistant steel plate refers to a special plate product designed for use under large-area wear conditions. Commonly used wear-resistant steel plates are plate products made by cladding a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. Wear-resistant steel plates are widely used in engineering, mining, construction, agriculture, cement production, ports, electricity, metallurgy and other mechanical products that require high strength and high wear resistance under particularly harsh working conditions.

[0003] A Chinese patent with publication number CN215850051U discloses a composite wear-resistant steel plate. The composite wear-resistant steel plate comprises: a steel plate, the steel plate comprises a substrate, the outer surface of the substrate is fixedly connected with a high chromium alloy, the outer surface of the high chromium alloy is fixedly connected with chromium carbide, the thickness of the substrate is above 3 mm, the thickness of the high chromium alloy is 1 mm, and the thickness of the chromium carbide is above 1.5 mm. The composite wear-resistant steel plate provided by the utility model provides protection for the substrate and improves the wear resistance of the substrate by arranging a layer of high chromium alloy and chromium carbide on the outside of the substrate, because chromium carbide has excellent wear resistance and loss resistance, which can improve the wear resistance of the steel plate, and the high chromium alloy has good toughness and strong wear resistance, so the steel plate has excellent impact resistance and deformability, and can curl with the substrate and chromium carbide to avoid wear between the substrate and chromium carbide when the steel plate is impacted.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: during the processing and use of wear-resistant steel plates, the flatness of the side of the steel plate largely determines the wear resistance of the steel plate during use.

[0029] like Figure 1-Figure 4 As shown, the composite wear-resistant steel plate proposed by the utility model includes a steel plate 1, a wear-resistant layer 2, a shell 3, a support plate 4, a support rod 5, a lifting spring 6, a spring plate 7, a rotating bracket 8, a rotating shaft 9, a guide plate 10, a top plate 11, a threaded member 12, a threaded rod 13, a limit knob 14, a sliding locking member 15, a threaded damping member 16, a sliding shell 17, a turntable 18, a lifting threaded rod 19, a transmission protrusion 20, a transmission telescopic rod 21, a transmission member 22, a pressing plate 23 and a lifting limit member 24;

[0030] Symmetrical wear-resistant layers 2 are provided on both sides of the steel plate 1; a support plate 4 is provided inside the shell 3; the bottom is in contact with the support plate 4; a support rod 5 is provided on the side of the shell 3; a lifting spring 6 is provided on the top of the support rod 5; a spring plate 7 is provided on the end of the lifting spring 6 away from the support rod 5; a rotating bracket 8 is provided on the top of the spring plate 7; a rotating shaft 9 for rotational connection is provided on the side of the rotating bracket 8; a guide plate 10 is provided on the side of the rotating bracket 8; symmetrical rotating brackets 8 are provided on both sides of the rotating shaft 9;

[0031] A top plate 11 is provided on the top of the housing 3; a lifting and lowering adjustment structure is provided on the top plate 11; a rotatably connected turntable 18 is provided on the top of the top plate 11; a rotating structure for adjusting the pressing effect is provided on the turntable 18;

[0032] The adjustment structure includes a threaded member 12; a limiting groove is provided on the housing 3, and the threaded member 12 contacts and squeezes the inner wall of the limiting groove; a threaded rod 13 is provided on the side of the threaded member 12 for threaded connection; a rotating connecting member 25 is provided on the threaded rod 13 for rotational connection; a sliding housing 17 is provided on the top of the rotating connecting member 25; a sliding stopper 15 is provided on the side of the inner wall of the sliding housing 17 for sliding connection; a threaded damping member 16 is provided on the side of the sliding housing 17; the side of the threaded damping member 16 contacts and squeezes the side of the sliding stopper 15; a limiting knob 14 is provided on the top of the threaded rod 13; a groove is provided on the side of the limiting knob 14, and the inner wall of the groove of the sliding stopper 15 is in sliding contact;

[0033] The rotating structure includes a lifting threaded rod 19; the turntable 18 is rotatably connected to the top plate 11; the turntable 18 is threadedly connected to the lifting threaded rod 19; a pressing plate 23 is provided on the bottom of the lifting threaded rod 19; a symmetrical lifting limiter 24 is provided on the side of the pressing plate 23; the lifting limiter 24 is slidably connected to the side of the shell 3; a plurality of groups of transmission protrusions 20 are provided on the side of the turntable 18; a transmission telescopic rod 21 is provided on the top of the top plate 11; a transmission member 22 is provided on the output end of the transmission telescopic rod 21; the transmission member 22 is in contact with the side of the transmission protrusion 20.

[0034] In this embodiment, the device can effectively improve the flatness processing of the side of the steel plate 1. By improving the flatness of the side of the steel plate 1, the contact area of ​​the wear-resistant layer 2 is more uniform when friction occurs when the wear-resistant layer 2 contacts other equipment, thereby ensuring the wear resistance of the device.

[0035] By placing the steel plate 1 on the support plate 4, the device can facilitate the flatness processing process. The spring plate 7 is driven to rise and fall and slide by the lifting spring 6, and the rotating shaft 9 is driven to rotate by the rotating nail 8. The combination of the rotating shaft 9 and the rotating bracket 8 can facilitate the device to push the feeding. At the same time, the structure of the lifting spring 6 can prevent the steel plate 1 from being rigidly supported during the pressing flatness processing of the device, thereby preventing the edge of the steel plate 1 from warping due to the rotating shaft 9 during the pressing process.

[0036] The limit knob 14 is driven to rotate by the threaded rod 13, the threaded member 12 and the threaded rod 13 are threadedly rotated, and the threaded rod 13 and the rotating connecting member 25 are rotated, so that the height change of the rotating connecting member 25 is realized during the rotation process of the threaded member 12, and the rotating connecting member 25 is connected to the top plate 11, so as to realize the effect of adjusting the height of the top plate 11 by rotating the threaded rod 13. When the threaded rod 13 is rotated to a certain angle, the sliding locking member 15 and the sliding shell 17 slide, and the sliding shell 17 and the threaded damping member 16 are threadedly rotated, so that the limit knob 14 is locked by the sliding locking member 15 to prevent the limit knob 14 from rotating. At the same time, the threaded damping member 16 locks the current height of the sliding locking member 15 to prevent the sliding locking member 15 from accidentally sliding downward, thereby ensuring the stable locking performance of the device for the rotation angle of the threaded rod 13 and ensuring that the height of the top plate 11 will not change during the processing of the device.

[0037] The lifting threaded rod 19 is driven to lift and slide by the turntable 18, and the bottom of the lifting threaded rod 19 is connected to the pressing plate 23, and the transmission member 22 is driven to slide by the transmission telescopic rod 21, and the transmission protrusion 20 is driven to rotate by the transmission member 22, and the turntable 18 is driven to rotate by the transmission protrusion 20, so that the height of the pressing plate 23 is controlled by the rotation angle of the turntable 18, and the downward pressing force of the pressing plate 23 can be accurately controlled by the transmission telescopic rod 21 through the transmission mode of the transmission telescopic rod 21, thereby ensuring the accuracy of the flatness pressing processing, and the lifting and sliding of the pressing plate 23 can be limited by the structure of the lifting limiter 24 symmetrical on the side, thereby preventing the pressing plate 23 from tilting during the lifting and sliding process, and ensuring that the steel plate 1 is subjected to the same pressing force at each position.

[0038] Embodiment 2

[0039] like Figure 1-Figure 4 As shown, the utility model proposes a composite wear-resistant steel plate.

[0040] The combined structure of the rotating connector 25 and the pointer allows the staff to confirm the current rotation angle of the threaded rod 13, so that when the multiple groups of threaded rods 13 are rotated and adjusted, it is convenient to control the rotation angles of the multiple groups of threaded rods 13 to be the same, thereby ensuring that the top plate 11 is level.

[0041] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or in different embodiments may also be combined.
