Abstract
The utility model discloses a split type cemented carbide wearing-resistant glass plate, comprising a glass plate body and a lower matrix. A guiding hole is disposed in a feeding hole wall in the glass plate body. The middle part of the glass plate body is provided with two protruding blocks having a bolt hole evenly and respectively. The upper surfaces of the two protruding blocks are respectively provided with a groove. A metal block is fixedly connected to the groove. The upper surface of the metal block is welded and fixed to a cemented carbide layer. The lower matrix is provided with a guiding ring, and the inner wall of the guiding ring is welded and fixed to the cemented carbide layer. The lower matrix sleeves the glass plate body. The guiding ring is in a tight cooperation with the guiding hole. The split type cemented carbide wearing-resistant glass plate is advantageous in that with the adoption of the cemented carbide wearing layer, the wearing-resistant performance of the glass plate and the hardness of the work surface can be improved; with the adoption of a combined type separable connecting structure, the cemented carbide layer can be prevented from cracking when the conventional cemented carbide wearing layer is being welded due to the fact that the expanding and contracting coefficient of the body material and that of the cemented carbide are different; the structure is simple, producing is easy, and usage cost is low.
Description
Technical field
The utility model relates to the accessory that concrete conveying equipment is used, and relates to specifically the split-type hard alloy wear resistance of using on a kind of concrete pump glasses plate.
Background technique
Anti-wear wear plate and cutting ring are vitals very in mixed earth transfer pump, are also easily damaged partss.Mixed earth is in course of conveying, the alternate run that cutting ring and glasses plate come and go due to charging and feeding is between two feeding holes, glasses plate and cutting ring interact, can produce frequently and clash into, can cause carbide ring to collapse piece, particularly the bridge of the nose position of glasses plate, understand fracture and fall fast phenomenon, cause glasses plate not high working life, therefore need often to change.
The making method of the Anti-wear wear plate of currently available technology has the method that adopts disposable integral build-up wear-resistant layer, also the method that adopts the whole hard alloy ring, the method that also has cemented carbide rings etc. is arranged, the common ground of this several method is all to adopt whole fixedly glasses plate, its deficiency is after cemented carbide damages, all the glasses plate integral replacing must be fallen, the waste material, increase operating cost.
The model utility content
The utility model is for above-mentioned the deficiencies in the prior art, but and provides the split-type hard alloy wear resistance glasses plate of a kind of durable wear, shock resistance, the local replacing that resistance to wears.
split-type hard alloy wear resistance glasses plate of the present utility model, formed by glasses plate body and lower substrate, the intrinsic pan feeding hole wall of described glasses plate is provided with pilot hole, there are two projection pieces that are evenly equipped with bolt hole glasses plate body intermediate portion, two projection piece upper surfaces all are provided with groove, be fixedly connected with slug in described groove, described slug upper surface is welded with hard alloy layer, described lower substrate is provided with guide ring, described guide ring inwall is welded with hard alloy layer, described lower substrate is sleeved on the glasses plate body, described guide ring and pilot hole closely cooperate.
Be bolted to connection between described slug, lower substrate and glasses plate body.The cemented carbide layer thickness of described slug upper surface and the welding of guide ring inwall is 2-10mm.The hard alloy layer of described slug upper surface and guide ring inwall is welded and fixed by brazing.Described hard alloy layer is the hard alloy blocks of an integral body.Described hard alloy layer is the hard alloy blocks of 2-8 piece piecemeal combination.
The beneficial effects of the utility model are:
(1) adopt hard alloy abrasion-resistant layer to improve the hardness of wear-resisting property and the working surface of glasses plate;
(2) adopt the separable linkage structure of split-type cemented carbide, while having avoided traditional hard alloy abrasion-resistant layer welding, the different hard alloy layer cracking that causes of bulk material and cemented carbide dilation coefficient;
(3) simple in structure, be easy to make, user cost is low.
