Abstract
The utility model relates to a wear-resistant strip and a wear-resistant ring with hard alloy structure, which solves the problems of the existing wear-resistant strip and the existing wear-resistant ring that the service lives are short, so the number of times of maintenance and replacement can be reduced and the efficiency of conveying concrete by a concrete pump truck can be enhanced. The wear-resistant strip comprises a base, wherein, the wear-resistant layer on the surface of the base is jointed by bar-shaped or block-shaped hard alloy base slices which are arranged at intervals, and the intervals among the hard alloy base slices are provided with metal filler which is used for high temperature sintering. The wear-resistant layer on the surface of the wear-resistant ring is same with the wear-resistant strip. The wear-resistant surfaces of the wear-resistant ring and the wear-resistant strip adopts hard alloy, and the degree of rigidity of the welded hard alloy is ensured with the aid of new style solder and high temperature sintering process; thereby, compared with wear-resistant layer formed by the build-up welding of wear-resistant welding rods, the wear resistance of the utility model is higher for several times, even tens of times, and the service lives of the wear-resistant strip and the wear-resistant ring can be prolonged; though the price is higher than the build-up welded wear-resistant strip and the build-up welded wear-resistant ring, the cost performance of the utility model is higher than the prior art; simultaneously, the number of times of the maintenance and the replacement is reduced, so the direct and the indirect economic benefits are both arresting.
Description
Technical field: it is C type valve concrete pump accessory that the utility model relates to a kind of building machinery.
Background technique: at present, the wear rib and the wear-resisting circle that use in C type valve concrete pump are the even parts of a pair of friction, also are a pair of easily damaged partss simultaneously.They the time are bearing heavily stressed abrasive wear and shear load in work, under a kind of like this force-bearing situation of complexity, make the very fast inefficacy of wear rib and wear-resisting circle.For this reason, some engineers and technicians have done a lot of work, and it is increased the service life as far as possible.As: select cast abrasion-resistant alloy for use; Perhaps build-up wear-resistant alloy on the Ordinary Steel steel plate; Its effect is all not ideal.Wearing and tearing have appearred in wear rib and wear-resisting circle at work soon; this to friction pair in; the gap is strengthened gradually; be easy to enter bigger abrasive particle; thereby wearing and tearing have further been aggravated; caused the inefficacy of wear rib and wear-resisting circle, concrete mixer is had to shut down replacing, makes the efficient of delivering concrete reduce.
Summary of the invention: the utility model purpose is in order to improve the working life of wear rib and wear-resisting circle, thereby reduces the number of times of maintain and replace, improves the efficient of concrete mixer delivering concrete.
The wear rib that the utility model provides with cemented carbide structure, comprise a strip wear rib matrix, wearing layer on the matrix working surface, wearing layer is spaced to tile by bar or block carbide matrix this film to be formed, and is the metal charge that is used for high temperature sintering in the carbide matrix this film interval.
The carbide matrix this film be shaped as " rectangle ", " trapezoidal ", " rhombus ", " parallelogram ", " triangle ", " Z type ", " T type ", and can be combined into " polygonal " on the complete plane of wearing layer.Metal charge in the basic sheet interval preferably adopts the copper-manganese-nickel scolder.
With the matching used wear-resisting circle of above-mentioned wear rib with cemented carbide structure with cemented carbide structure, comprise a circular base, wearing layer on the matrix working surface, wearing layer is spaced to tile by bar or block carbide matrix this film to be formed, and is the metal charge that is used for high temperature sintering in the carbide matrix this film interval.
The carbide matrix this film be shaped as " rectangle ", " trapezoidal ", " rhombus ", " parallelogram ", " triangle ", " Z type ", " T type ", and can be combined into " polygonal " on the complete plane of wearing layer.Metal charge in the basic sheet interval preferably adopts the copper-manganese-nickel scolder.
The utility model advantage: 1, adopt the wearing face of cemented carbide as wear rib and wear-resisting circle, and compare with the wearing layer of wear resistance electrode built-up welding, its wear-resisting property exceeds several times even tens times, thus the working life of having improved wear rib and wear-resisting circle greatly; 2, novel scolder and high-sintering process have guaranteed the fastness that cemented carbide welds; Though the wear rib of 3 cemented carbide structure exceeds than the wear rib of built-up welding and the price of wear-resisting circle with wear-resisting round price, but the former is that be that prior art will exceed several times even tens times than the latter this novel working life, therefore its price performance will be far longer than prior art, also reduced the number of times of maintain and replace simultaneously, its direct economic benefit and indirect economic effect are all considerable.

Embodiment:
As shown in Figure 1, wear rib with cemented carbide structure, comprise a strip wear rib matrix 1 that processes by steel plate, wearing layer on it is spaced to tile by bar or block carbide matrix this film 2 to be formed, and is the metal charge 5 that is used for high temperature sintering in the carbide matrix this film interval.
Wherein, the shape of bar on the wearing layer or block carbide matrix this film can be a kind of in as shown in Figure 3 the different shape, as " rectangle ", " trapezoidal ", " rhombus ", " parallelogram ", " triangle ", " Z type ", " T type ", and can be combined into " polygonal " on the complete plane of wearing layer.The shape of the basic sheet of this example is selected rectangle for use.
Metal charge in the carbide matrix this film interval preferably adopts the copper-manganese-nickel scolder, wherein can add an amount of solder flux, welds with the method for high temperature sintering then, to guarantee the fastness of its welding.
As shown in Figure 2, for with the matching used wear-resisting circle of wear rib, comprise a circular base 3 that processes by steel plate, wearing layer on the matrix working surface is spaced to tile by bar or block carbide matrix this film 4 to be formed, and is the metal charge 5 that is used for high temperature sintering in the carbide matrix this film interval.Wherein the shape of basic sheet is seen Fig. 3, and the metal charge in the shape of basic sheet and the basic sheet interval is identical with wear rib.
