Abstract
The utility model discloses a cascade composite board of copper-free sintering layer, aiming at providing a simple process to avoid sintering copper powder metal, materials and non-metallic cascade composite board. The utility model comprises a metal base-material and a non-metallic material for reducing a friction which is arranged in the surface of the metal base-material, which is characterized in that a trench is arranged in the metal base-material which is between the metal base-material and the non-metallic material for reducing the friction. The structure can put the non-metallic material for reducing the friction into the trench which is arranged in the surface of the metal base-material by sintering and melting, an attachment area can be increased, in particular to the trench with section shape that the up-port is small and the bottom is big, the non-metallic material can be firmly fixed for reducing the friction in the trench, the adhesion is strong, the metal base-material will not separated from the non-metallic material for reducing the friction in using or in processing, the technique of sintering the copper and the copper powder is not required, the energy consumption and the product cost are reduced, which is conducive to environmental protection.
Description
Technical field
The utility model relates to a kind of composite board, relate in particular to a kind of on metal material the laminated composite plate of sintering nonmetallic materials.
Background technology
Metal material, macromolecular material and ceramic material etc. all possess some good points on serviceability and are not enough, and the range of application of oneself is respectively arranged.Along with science and technology development, also more and more higher to the requirement of material, use single material to satisfy various requirement and seem more and more difficult and uneconomical.Therefore, composite board has appearred, at present, the general laminated composite plate of Shi Yonging, as steel-copper-nonmetallic materials, be used to make the composite board of oil-free lubrication sliding bearing, the general manufacturing process of these composite boards is: the sheet material of specific thickness is smoothed in cutting steel plate-surface of steel plate shop copper powder sintering-smoothing-surface nonmetal antifriction material sintering-rolling in shop, make the blank of making sliding bearing, formation of parts as requested again, because the inconsistency of steel and nonmetallic materials physical property is as the thermal expansion factor difference, at high temperature work, crease easily or the material faying face between separate; Plate material is in the process of bending forming, because the curvature difference of material ectonexine also can cause the separation between the material faying face.Therefore, generally spread the spherical copper powder sintering in the production,, improve the adhesive force of nonmetal antifriction material and base steel material surface, make both not easily separated with roughness and the formation space that increases steel material primary surface at the material primary surface of steel.And copper powder sintering process complexity, difficult quality control consumes copper powder again, and product cost greatly improves.
Summary of the invention
The purpose of this utility model be to provide a kind of technology simple, can exempt the metal material of copper powder sintering layer and the laminated composite plate of nonmetallic materials.
In order to reach above-mentioned requirements, the technical scheme of exempting from the laminated composite plate of copper powder sintering layer is: it comprises metal base and by the nonmetal antifriction material of sintering attached to metallic substrate surface, it is characterized in that being shaped on groove on the metal base between metal base and the nonmetal antifriction material.
The laminated composite plate of exempting from copper powder sintering layer according to the said structure manufacturing, can be melted to nonmetal antifriction material in the groove of metallic substrate surface by sintering, traction-increasing surface is long-pending, especially the big groove in section configuration little bottom surface suitable for reading, can be engaged in nonmetal antifriction material in the groove securely, have extremely strong adhesive force, do not separate with nonmetal antifriction material no matter in processing or use, all can not produce metal base; Exempt the technology of sintered copper powder, save copper powder, reduce energy resource consumption, product cost, be beneficial to environmental protection again.

Wherein: 1, metal base; 2, surface; 3, groove; 4, sideline; 5, nonmetal antifriction material.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1, Fig. 2, Fig. 3 are the structural representations that has staggered trapezoidal groove on metal base.There is longitudinal and transverse staggered trapezoidal groove 3 on surface 2 at metal base 1 by cutting and/or press process.The arrangement of groove 3 can also be to be arranged in parallel as shown in Figure 4.Groove 3 can become certain included angle with the sideline 4 of base material 1, and as 30 degree, 60 degree etc., shown in Figure 5 is groove 1 and 4 one-tenth miter angles in sideline of base material 1.The shape of groove 3 sections can by cutting and/or press process triangularity as shown in Figure 6 or rectangle as shown in Figure 7 semicircle as shown in Figure 8 or the combination of triangle and rectangle as shown in Figure 9 or the combination of semicircle and rectangle wait the combination of other geometries as shown in figure 10.After the metal base 1 of with groove 3 makes, spread nonmetal antifriction material 5 sintering again on the surface 2 of base material 1 by traditional handicraft, rolling again, as to smooth specific thickness sheet material becomes the finished product of laminated composite plate.Such structure can embed nonmetal antifriction material 5 in the groove 3, groove 3 shapes especially as shown in Figure 3, and bonding strength is higher.Can exempt the technology of sintered copper powder, the performance of gained composite board is suitable with the composite board that had copper powder sintering layer originally.
Claims (4)
