Abstract
Provided is an anti-wear wear plate, which mainly resolves the problem that most existing anti-wear wear plates adopt rigid alloy which can not bear strong impact. The anti-wear wear plate comprises a wear plate body (1), two stack welding inner rings (4) and a spectacle-shaped integral ring (5). The spectacle-shaped integral ring (5) is arranged between the periphery of the two stack welding inner rings (4) and the two stack welding inner rings (4) on a working face of the wear plate body (1) by stack welding, and the outside of the spectacle-shaped integral ring (5) protrudes out of the working face of the wear plate body (1) and at the same level with or higher than the outer ends of the two stack welding inner rings (4). An anti-wear stack welding inner sleeve and the spectacle-shaped integral ring (5) arranged on the working face of the wear plate body (1)are formed by one step on a processing device so as to satisfy technological requirements of a concrete conveying pump. Accordingly, the anti-wear wear plate is good in overall structure, capable of prolonging service life of a cutting ring by multiple times and widely applicable to technological devices like the concrete conveying pump.
Description
Technical field
The utility model relates to a kind of cutting ring, particularly a kind ofly is used for the glasses plate that concrete pump is used.
Background technique
The construction of engineerings such as tall building, dam, airport, tunnel; Broken away from already now carry on the shoulder, the car handling send concrete method; And adopt concrete pump to carry; After the wear-out part cutting ring employing iron-base hard alloy material of people in 1999, improved 8-10 its working life doubly to transfer pump.But along with the development of building industry, particularly the construction of the tall building more than 100 meters and cement grade are brought up to 100-120 from 30-50, and the wearing and tearing of wear-out part cutting ring are accelerated; The average use will be changed in one, two day; The shortening in cutting ring working life might cause the concrete gambling plug of up to a hundred meters conveyance conduits, and its dismounting maintenance work difficulty is well imagined; Increase labor intensity greatly, directly influenced construction speed and working efficiency.At present; The concrete pump of tall building need strengthen this technical barrier of propelling pressure; Because pump king's invention and manufacturing; Achieve a solution, but the quick loss of wear-out part pumping hole cutting ring has become the technical barrier of tall building concrete pump proper functioning, and this technical barrier ubiquity at home and abroad.
Glasses plate and cutting ring are that concrete pump (concrete pump) is gone up a pair of parts that closely cooperate and have relative movement that use, and the cutting ring of when pump concrete, swinging plays dissection to concrete.Because what pass through in the feeding hole of glasses plate and cutting ring is concrete, therefore the fitting surface to glasses plate and cutting ring feeding hole inwall and glasses plate and cutting ring is that cutting surface will carry out Wear-resistant Treatment.
At present; A kind of cemented carbide glasses plate commonly used; Its structure is as shown in Figure 1; It comprises the glasses plate matrix be contained in the carbide ring on the glasses plate matrix cutting surface, its described carbide ring is combined into by some hard alloy blocks on hoop, the cemented carbide intra-block edge is turned back and is extended in feeding hole along the feeding hole inwall on the glasses plate matrix; In the feeding hole of glasses plate matrix, be combined into the cemented carbide annulus that is attached to the feeding hole inwall, leave straight line shape gap between the adjacent hard alloy blocks in cutting surface place and feeding hole; The approximal surface of described hard alloy blocks and described glasses plate matrix welds together, and is full of solder flux in the straight line shape gap between the adjacent hard alloy blocks.Though because of cemented carbide hardness is high, hold and can't stand superpower impact force, particularly because the increase of the discharge pressure tenfold of transfer pump; Impact force is bigger; Very easily the carbide ring cut-out is fallen the bridge of the nose position of piece, particularly glasses plate when making shear action, fracture can be taken place and fall the piece phenomenon with cutting ring; The result is that the fragility of cemented carbide is just more outstanding, causes the glasses plate life-span to be fallen sharply.At present, many improved methods are also arranged, but effect is all not ideal enough.
Like the SANY Heavy Industry Co., Ltd of economic technical development area, Changsha, Changsha, Hunan in " glasses board for concrete pump and the cutting ring " of application on November 16th, 2007 patent of invention (applications/patents number: 200710187135.3; Open/notification number: CN101158347; Open/day for announcing: on April 9th, 2008); The invention discloses a kind of glasses board for concrete pump and cutting ring; Comprise matrix and be contained in the carbide ring on the matrix cutting surface, described carbide ring is combined into by some hard alloy blocks on hoop, and the cemented carbide intra-block edge is turned back and extended in feeding hole along the feeding hole inwall on the matrix; In the feeding hole of matrix, be combined into the cemented carbide annulus that is attached to the feeding hole inwall, in cutting surface place and feeding hole, leave straight line shape gap between the adjacent hard alloy blocks; The approximal surface of described hard alloy blocks and described matrix welds together, and is full of solder flux in the straight line shape gap between the adjacent hard alloy blocks.It is through on hoop, being combined into carbide ring by some hard alloy blocks; And it is welded together at approximal surface with matrix; To make it to reach wear-resisting and shock proof effect; Its processing technology of the cutting ring of this kind mode structure is complicated, and still unresolved cemented carbide can not bear the problem of superpower impact force, thereby makes cost of production and user cost increase.
And for example the Dai Hanchen in 16 406 in zhuzhou, hunan province city arrowhead Tang Hongwei village is in " a kind of glasses plate and the cutting ring and preparation process thereof that is used on the concrete pump " of application on January 6 calendar year 2001 patent of invention (applications/patents number: CN01106822.1; Open/notification number: CN1304812, open/day for announcing: July 25 calendar year 2001).It is to tumble in the alloy body that one deck adopts cemented carbide to process on the surface of original glasses plate and cutting ring.Also be the most original method, also unresolved cemented carbide can not bear the problem of superpower impact force.
Summary of the invention
