Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to a steel-based copper alloy slide plate. Background Art

[0002] Slide plates play an important role in machining, such as reducing the friction resistance between the sliders of the mold to ensure the normal operation of the mold.

[0003] In the prior art, there are several structures of skateboards: 1. A skateboard made entirely of copper alloy; 2. A skateboard made entirely of steel or cast iron; 3. A skateboard made by laminating a copper alloy skateboard onto a steel surface using screws.

[0004] Although the skateboard made of copper alloy has good wear resistance and a small friction coefficient, copper is expensive and the cost is too high, making it unsuitable for large-scale production; although the skateboard made of steel or cast iron as a whole has a low cost, the steel skateboard is prone to bonding when rubbing against the steel material, and it is necessary to process knurling grooves and lubricate it on its surface, which is troublesome to operate. In addition, the scope of application of steel skateboards is small and limited, and some mechanical parts or molds do not allow the addition of structures to the skateboard in use; the skateboard made by compounding the copper alloy skateboard on the steel surface with screws has good wear resistance and a small friction coefficient, but its process is complicated and the accuracy is poor when used. In summary, the skateboards in the prior art have the disadvantage of not being able to reduce costs while having both functionality and high bonding strength. Utility Model Content

[0017] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0018] See also Figures 1 to 3 , which is a schematic structural diagram of a steel-based copper alloy slide provided by the present invention. The steel-based copper alloy slide comprises a base steel plate 10, a plurality of chamfers 20 provided on the base steel plate 10, a plurality of connecting grooves 30 provided on the base steel plate 10, a plurality of knurled grooves 40 provided on the base steel plate 10, and a copper alloy working layer 50 provided on the base steel plate 10. It is conceivable that the steel-based copper alloy slide also includes other functional modules, such as positioning holes, etc., which are well known to those skilled in the art and will not be described in detail here.

[0019] The shape of the base steel plate 10 is matched with the shape of the copper alloy working layer 50, so that the base steel plate 10 and the copper alloy working layer 50 form a complete slide plate. The base steel plate 10 is provided with a mounting notch, so that the outer contour of the base steel plate 10 is arranged in a two-layer stepped shape. The base steel plate 10 includes a first plane 11, a first side surface 12 connected to and perpendicular to the first plane 11, a second plane 13 connected to and perpendicular to the first side surface 12, a second side surface 14 connected to and perpendicular to the second plane 13, and a third plane 15 connected to and perpendicular to the second side surface 14. The first side surface 12, the second plane 13, the second side surface 14 and the third plane 15 are bonding surfaces bonded to the copper alloy working layer 50 by ion penetration. The ion penetration method is to coat an alloy film layer on the surface of the substrate steel layer 10 and cast a liquid copper alloy on the alloy film layer. Through high-temperature infiltration, the iron atoms of the base steel layer 10 and the copper atoms of the copper alloy working layer 50 penetrate the alloy thin film layer and fully exchange at the boundary of the alloy thin film layer, forming a high-strength metallurgical structure. The provision of the base steel plate 10 is used to reduce the unused volume of the copper alloy working layer 50, thereby reducing production costs. The ion permeation method is a common technology and will not be described in detail here.

[0020] The chamfers 20 are provided at the intersections of the first plane 11 and the first side surface 12, the second plane 13 and the second side surface 14, and the third plane 15 and the second side surface 14. When the copper alloy working layer 50 solidifies on the base steel plate 10, the chamfers 20 increase the contact area between the base steel plate 10 and the copper alloy working layer 50 at the intersection, reducing the pressure exerted by the base steel plate 10 on the copper alloy working layer 50, thereby preventing cracking of the copper alloy working layer 50. The chamfers 20 are provided in an arc shape, allowing the liquid copper alloy to flow smoothly during casting, thereby reducing the contact area between the liquid copper alloy and air and, in turn, reducing the oxidation rate of the copper alloy working layer 50.

[0021] Multiple connecting grooves 30 are vertically and symmetrically arranged on the first side surface 12 and the second side surface 14. One end of the connecting groove 30 on the first side surface 12 extends to the first plane 11, and the ends of the connecting groove on the second side surface 14 extend to the second plane 13 and the third plane 15, respectively. The arrangement of the connecting grooves increases the contact area between the base steel plate 10 and the copper alloy working layer 50 to enhance the bonding strength. In this embodiment, the cross-sectional profile of the connecting grooves 30 is rectangular, so that the copper alloy working layer 50 cast in the connecting grooves 30 forms a columnar structure that snaps into place, thereby enhancing the bonding strength between the base steel plate 10 and the copper alloy working layer 50. The bottom surface of the connecting grooves 30 on the first side surface 12 is higher than the second plane 13, allowing the connecting grooves 30 to be arranged on the base steel plate 10 without affecting the stability of the base steel plate 10.

[0022] The knurled grooves 40 are provided on the second plane 13, the second side surface 14, and the third plane 15. The knurled grooves 40 are arranged in a mesh pattern. The knurled blades 40 increase the contact area between the base steel plate 10 and the copper alloy working layer 50, thereby increasing the bonding strength between the copper alloy working layer 50 and the base steel plate 10.

[0023] The copper alloy working layer 50 is shaped like a frame with two right-angle bends. It is contemplated that the copper alloy working layer 50 can be configured in other different shapes depending on the mold shape used in actual production. The copper alloy working layer 50 is positioned between the sliders of the mold to reduce friction between the sliders and ensure proper operation of the mold.

[0024] Compared with the prior art, the utility model provides a steel-based copper alloy skateboard which reduces the production cost of the steel-based copper alloy skateboard by providing the base steel plate 10 and the copper alloy working layer 50, and strengthens the bonding strength between the base steel plate 10 and the copper alloy working layer 50. The base steel plate 10 is provided with a mounting notch, and the outer contour of the base steel plate 10 is arranged in a two-layer stepped shape. The arrangement of the base steel plate 10 is used to reduce the volume of the useless copper alloy working layer 50 and reduce production costs. The chamfer 20 is arranged in an arc shape at the intersection to prevent the copper alloy working layer 50 from cracking and reduce the oxidation rate of the copper alloy working layer 50. The connecting groove 30 is used to form the copper alloy working layer 50 cast in the connecting groove 30 into a columnar structure and insert it therein, thereby strengthening the bonding strength between the copper alloy working layer 50 and the base steel plate 10. The knurled grooves 40 are arranged in a mesh shape, which increases the contact area between the base steel plate 10 and the copper alloy working layer 50 to increase the bonding strength between the copper alloy working layer 50 and the base steel plate 10 .

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
