Description
Technical field
The present invention relates to concrete pumping equipment, particularly, relate to a kind of glasses plate for concrete mixer.
Background technique
Concrete uninterrupted pumping is formed by cutting ring fast shut-off concrete column on glasses plate, therefore, the cutting edge of glasses plate and cutting ring very easily damages, and causing glasses plate and cutting ring is easily damaged parts on the concrete pumping equipment (for example, dragging pump, Vehicle loaded pump, concrete mixer etc.).For the cutting edge that prevents glasses plate and cutting ring damages, the technology that adopts at present for wear ring welding-on that cemented carbide is made on the operative end surface of glasses plate and cutting ring.
Shown in Fig. 1 is the plan view of glasses plate in the prior art, and Fig. 2 is the A-A sectional view of this glasses plate.As can be seen from the figure, glasses plate comprises glasses plate matrix 20, two wear rings 10 and polylith wear-resistant block 30.Be provided with on the glasses plate matrix 20 23, two wear rings 10 of two through holes respectively around the axis welding-on of two through holes 23 on glasses plate matrix 20.Polylith wear-resistant block 30 is welded on the glasses plate matrix 20.Wear ring 10 and wear-resistant block 30 have respectively an end face and glasses plate matrix 20 to fit, and another end face of wear ring 10 and wear-resistant block 30 forms the operative end surface of glasses plate.Wear ring 10 and wear-resistant block 30 are made by cemented carbide usually, and glasses plate matrix 20 is made by common iron.
During welding wear-resistant block 30, weld tabs and auxiliary material shop need to be sprinkled upon on the glasses plate matrix 20, then carrying out integral body after wear-resistant block 30 and glasses plate matrix 20 being assembled heats, make the temperature integral body of wear-resistant block 30 and glasses plate matrix 20 be increased to about 900 ℃, insulation 2min to 5min, the cooling of coming out of the stove, thus wear-resistant block 30 and glasses plate matrix 20 are welded together.But under such high temperature, wear-resistant block 30 and glasses plate matrix 20 have all produced larger expansion, and the coefficient of dilatation of the coefficient of dilatation of glasses plate matrix 20 and wear-resistant block 30 differs large (poor about 3 times usually).When coming out of the stove cooling, wear-resistant block 30 shrinks less, and glasses plate matrix 20 then contraction is larger.Because wear-resistant block 30 has been welded on the end face of glasses plate matrix 20, therefore can stop the contraction of this end face, thereby cause the serious warpage of glasses plate, be welded with the head face hump of wear-resistant block 30, another end face is recessed.In order to make glasses plate smooth, following several method is arranged:
1, the operative end surface of glasses plate is carried out grinding.But the grinding capacity of this method is larger, thereby has caused very large waste;
2, make wear-resistant block 30 with the lower cemented carbide of Tungsten carbite content, thereby make wear-resistant block 30 have preferably toughness.But the wear resistance of this wear-resistant block 30 is relatively poor.
Therefore, the distortion that how to reduce to weld wear-resistant block 30 rear glasses plate becomes the technical problem that related domain needs to be resolved hurrily.
Summary of the invention
The purpose of this invention is to provide a kind of glasses plate, wear-resistant block is welded on the glasses plate distortion that obtains afterwards on the glasses plate matrix less.
To achieve these goals, the invention provides a kind of glasses plate, this glasses plate comprises glasses plate matrix, two wear rings and polylith wear-resistant block, be provided with two through holes on the described glasses plate matrix, described two wear rings are fixedly installed on the described glasses plate matrix around the axis of two described through holes respectively, and wherein, described glasses plate matrix comprises base plate and polylith liner plate, an end face of this polylith liner plate and described base plate are fitted, another end face and the corresponding applying of described polylith wear-resistant block.
