Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a steel-based copper alloy sliding plate. Background Technology

[0002] Sliders play an important role in machining. By reducing the frictional resistance between the sliders of a mold, the normal operation of the mold is ensured.

[0003] A Chinese patent website publishes patent number CN213776079U for a slide plate inlaid with solid lubricant particles in a steel-copper bimetallic composite material. This slide plate is a flat slide plate made of composite material. Its key feature is that, from bottom to top, the slide plate comprises a copper alloy layer, an intermediate fusion layer, and a low-carbon steel layer fused together. A recess is formed on the surface of the copper alloy layer, extending into the low-carbon steel layer. Solid lubricant particles are inlaid in these recesses, with the size of the particles matching the size of the recesses. The upper surface of the solid lubricant particles is flush with the surface of the copper alloy layer. Screw holes for fixing the particles are formed on the flat slide plate. This significantly reduces the cost of expensive copper alloy, and the strength of the low-carbon steel layer is much higher than that of the copper alloy. Because the friction-reducing material in the solid lubricant particles acts as a lubricant, the product does not require oil or grease lubrication during use, achieving low cost and high performance. It can be used in mechanisms such as mold guide plates where frequent movement is difficult and lubrication is not possible.

[0004] However, the slide plate with solid lubricant particles embedded in the bimetallic steel-copper alloy only has a copper alloy layer on one side that is more wear-resistant, which cannot meet the slider's requirement for a slide plate with wear resistance on multiple sides. Utility Model Content

[0005] In view of this, the present invention provides a steel-based copper alloy sliding plate to solve the above problems.

[0006] A steel-based copper alloy sliding plate is disposed within a slider. It includes a base steel plate and a copper alloy working layer that partially encloses the base steel plate. A bonding notch is provided at a corner of the base steel plate. The bonding notch is block-shaped, and the base steel plate is stepped in two stages. The base steel plate has a bonding surface for casting the copper alloy working layer. The copper alloy working layer and the base steel plate form a complete steel-based copper alloy sliding plate. The copper alloy working layer has a U-shaped cross-section. The copper alloy working layer has a working surface that contacts the slider.

[0007] Furthermore, the steel-based copper alloy slide plate includes a plurality of blind holes disposed on the surface of the copper alloy working layer, and a plurality of lubrication pillars disposed in the blind holes.

[0008] Furthermore, multiple blind holes are evenly spaced.

[0009] Furthermore, the size and shape of the lubrication column are the same as those of the blind hole.

[0010] Furthermore, the mating surface includes a first side surface disposed on the mating notch, a first plane disposed on the mating notch, a second plane opposite to the first plane, and a second side surface connecting the first plane and the second plane.

[0011] Furthermore, the working surface includes a third plane, a third side perpendicular to the third plane, and a fourth plane connecting the third side.

[0012] Furthermore, the area of ​​the third plane is smaller than the area of ​​the fourth plane.

[0013] Compared with existing technologies, the steel-based copper alloy sliding plate provided by this utility model reduces production costs by setting the shapes of the base steel plate and the copper alloy working layer. The base steel plate has a connecting notch, which is shaped to match the copper alloy working layer. The connecting notch is block-shaped, the base steel plate is stepped in two stages, and the copper alloy working layer has a U-shaped cross-section. The area of ​​the third plane is smaller than the area of ​​the fourth plane. The shape and size of the third plane are designed to match the size of its contact surface with the slider of the mold.

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] Please see Figures 1 to 3This is a structural schematic diagram of a steel-based copper alloy sliding plate provided by this utility model. The steel-based copper alloy sliding plate includes a base steel plate 10, a copper alloy working layer 20 that partially encloses the base steel plate 10, multiple blind holes 30 disposed on the surface of the copper alloy working layer 20, and multiple lubrication pillars 40 disposed in the blind holes 30. It is conceivable that the steel-based copper alloy sliding plate also includes other functional modules, such as a transition layer, which are technologies known to those skilled in the art and will not be described in detail here.

[0019] The steel-based copper alloy slide plate is installed in the slider of the mold to assist the mold in operating normally during processing.

[0020] A bonding notch 11 is provided at the corner of the base steel plate 10. In this embodiment, the bonding notch 11 is block-shaped, and the base steel plate 10 is stepped. The base steel plate 10 is used to reduce the volume of the copper alloy working layer 20 to reduce production costs. The bonding notch 11 is designed to work with the copper alloy working layer 20, thereby reducing the ineffective volume of the copper alloy working layer 20 and increasing the effective utilization area of ​​the copper alloy working layer 20, thus reducing production costs. The base steel plate 10 is provided with a bonding surface 12 for casting the copper alloy working layer 20. The bonding surface 12 includes a first side surface 121 on the bonding notch 11, a first plane 122 on the bonding notch 11, a second plane 123 opposite to the first plane 122, and a second side surface 124 connecting the first plane 122 and the second plane 123. The technology for bonding the copper alloy working layer 20 with the base steel plate 10 is a common technology and will not be described in detail here.

[0021] The copper alloy working layer 20 is partially wrapped around the mating surface 12 of the base steel plate 10, forming a complete steel-based copper alloy sliding plate with the base steel plate 10. In this embodiment, the cross-sectional shape of the copper alloy working layer 20 is U-shaped. The copper alloy working layer 20 has a working surface 21 that contacts the slider. The working surface 21 includes a third plane 211, a third side surface 212 perpendicular to the third plane 211, and a fourth plane 213 connecting the third side surface 212. The area of ​​the third plane 211 is smaller than the area of ​​the fourth plane 213. The shape and size of the third plane 211 are matched to the size of its contact surface with the slider of the mold. The copper alloy working layer 20 assists the slider on the mold to operate normally during processing. Because the copper alloy used has a low coefficient of friction, the friction experienced by the copper alloy working layer 20 is reduced, increasing the service life of the steel-based copper alloy sliding plate.

[0022] Multiple blind holes 30 are evenly spaced. The blind holes 30 are used to install the lubrication pillars 40, thereby reducing the coefficient of friction on the surface of the copper alloy working layer 20, thus reducing the friction experienced by the copper alloy working layer 20 and extending its service life.

[0023] The lubrication pillar 40 is the same size and shape as the blind hole 30, ensuring that the lubrication pillar 40 is disposed without gaps on the surface of the copper alloy working layer 20 and is flush with the surface of the copper alloy working layer 20. The lubrication pillar 40 uses solid lubricating particles. In this embodiment, the lubrication pillar 40 uses graphite as the material. Graphite is inexpensive and has a low coefficient of friction. During use, the graphite moves between layers due to friction, forming an oil layer on the surface of the copper alloy working layer 20, which prevents the copper alloy working layer 20 from contacting the mold, thereby reducing the frictional resistance experienced by the copper alloy working layer 20.

[0024] Compared with existing technologies, the steel-based copper alloy sliding plate provided by this utility model reduces production costs by setting the shapes of the base steel plate 10 and the copper alloy working layer 20. The base steel plate 10 has a connecting notch 11, which is shaped to match the copper alloy working layer 20. The connecting notch 11 is block-shaped, the base steel plate 10 is stepped in two stages, and the cross-sectional shape of the copper alloy working layer 20 is U-shaped. The area of ​​the third plane 211 is smaller than the area of ​​the fourth plane 213. The shape and size of the third plane 211 are matched to the size of its contact surface with the slider of the mold.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
