Abstract
The invention discloses a Y-shaped wear-resistant eyeglass sheet, which comprises an eyeglass sheet body and a hard alloy wear-resistant layer, wherein the hard alloy wear-resistant layer is on the working face of the eyeglass sheet body; hard alloy blocks are welded on the hard alloy wear-resistant layer; a fit clearance between each two adjacent hard alloy blocks is a Y-shaped clearance; and welding flux is filled in each Y-shaped clearance. The Y-shaped wear-resistant eyeglass sheet disclosed by the invention has the advantages that the overall wear-resisting property of the eyeglass sheet and the hardness of the working face are improved, and the phenomenon that a hard alloy layer is cracked due to the fact that the hard alloy layer is extruded due to the fact that body materials are different in expansion and shrinkage coefficient when integral hard alloy layer welding is performed is avoided, so that the service life of the Y-shaped wear-resistant eyeglass sheet is prolonged.
Description
Technical field
The present invention relates to the accessory that concrete conveying equipment is used, relate to specifically glasses plate and the manufacture method used on the concrete pump.
Background technique
Glasses plate is to protect the port of S pipe; play the parts of wear-resisting effect; it is the important easily worn part of mixed earth transfer pump; be related to the overall performance of cement pump its working life; in use; its destroyed form mainly is that glasses plate and cutting ring interact; to mixing the earth stone when doing shearing; because hard alloy abrasion-resistant layer is not disperseed impact force; cause carbide ring to collapse piece; particularly the bridge of the nose position of glasses plate is understood fracture and is fallen fast phenomenon, causes glasses plate not high working life.
Prior art forms hard alloy abrasion-resistant layer by whole built-up welding, but the build-up wear-resistant layer with respect to hard alloy blocks, its wear-resisting property and hardness are not satisfactory, especially to mixed earth stone doing when shearing, cause easily and burst apart, working life is lower.Adopt the method for whole hard alloy ring, the whole hard alloy ring has improved wear resistance and the impact of glasses plate working surface, yet it is can carbide ring different with the thermal expansion of glasses plate body and shrinkage coefficient and cause carbide ring to burst apart to add man-hour, when stone was sheared, effectively buffering did not cause fracture.
Summary of the invention
The problem that exists for solving above-mentioned prior art, the present invention aims to provide a kind of wear-resisting, shock resistance, wear-resistant Y-shaped Anti-wear wear plate.
For achieving the above object, the present invention adopts following technological scheme:
A kind of Y-shaped Anti-wear wear plate, comprise the hard alloy abrasion-resistant layer on glasses plate body and the working surface thereof, weld hard alloy blocks on the described hard alloy abrasion-resistant layer, the cooperation slit between the described hard alloy blocks is the Y-shaped slit, and described Y-shaped is full of solder flux in the slit.The quantity of described hard alloy blocks is 2 ~ 8.The thickness of described hard alloy abrasion-resistant layer is 2 ~ 10mm.The welding manner of described hard alloy blocks is brazing.Described Y-shaped slit is held to such an extent that clearance D is 0.1 ~ 3mm near plup inlet.Described Y-shaped slit edge line angle is 10 ~ 80 degree.Described Y-shaped slit is that a length is the parallel straight section of L at it near the plup inlet place, and length L is 1 ~ 3mm.
Second purpose of the present invention also is, a kind of making method of Y-shaped Anti-wear wear plate is provided, and its process step is: a kind of manufacture method of Y-shaped Anti-wear wear plate is characterized in that, process step comprises: 1. process the glasses plate body with plain carbon steel, machined grooves on its working surface; 2. add the brazing powder in the groove on the glasses plate body, hard alloy blocks is combined into annular along the groove of eye slab body; 3. at two pan feeding hole walls of glasses plate body, form pan feeding hole wall wearing layer with a built-up welding of carbide electrode, make the hard alloy blocks surface rubescent hard alloy blocks homogeneous heating on pan feeding hole wall wearing layer and the working surface with welding gun, by welding gun copper arc welding electrode is melted into copper water again and flows in the Y-shaped slit; 4. after the copper water-setting in Y-shaped slit is solid, again with welding gun place, glasses plate body welding slit is heated, copper water is melted.5. the glasses plate body is polished and then formed product to the welding part after naturally cooling off under the normal temperature state again.
The invention has the beneficial effects as follows:
(1) adopt hard alloy abrasion-resistant layer can improve the overall wear resistance energy of glasses plate and the hardness of working surface.
(2) adopt hard alloy blocks to weld mutually the form that connects, the different extruding cemented carbide layer that causes of bulk material dilation coefficient when having avoided the welding of integrated type hard alloy layer causes the hard alloy layer cracking.
(3) because hard alloy layer has hard alloy blocks to be spliced, and splicing place becomes the Y-shaped slit, it cooperates the slit to be full of cubond, so the mixed earth stone of glasses plate and cutting ring interaction partners is when doing shearing, form an interim damping of shocks district, can not cause rigid impact to hard alloy abrasion-resistant layer, improve its shock resistance.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in the figure, a kind of Y-shaped Anti-wear wear plate comprises the hard alloy abrasion-resistant layer on glasses plate body 1 and the working surface thereof, welding hard alloy blocks 2 on the described hard alloy abrasion-resistant layer, cooperation slit between the described hard alloy blocks 2 is Y-shaped slit 3, is full of solder flux in the described Y-shaped slit 3.The quantity of described hard alloy blocks 2 is 4.The thickness of described hard alloy abrasion-resistant layer is 6mm.The welding manner of described hard alloy blocks 2 is brazing.Described Y-shaped slit 3 is held to such an extent that clearance D is 1mm near plup inlet.Described Y-shaped slit 3 edge line angles are 30 degree.Described Y-shaped slit 3 is that a length is the parallel straight section of L at it near the plup inlet place, and length L is 2mm.
Gap between the hard alloy blocks 2 becomes Y-shaped slit 3 and has been full of solder flux, this Y-shaped gap is little in the gap of the face preparation of glasses plate, excesssive gap can cause wear-resisting property poor, little wear-resisting property and the shock resistance that can guarantee hard alloy abrasion-resistant layer in gap.When stone is sheared, the impact force that glasses plate cutting surface edge is subject to can disperse to be delivered to the glasses plate body by Y-shaped slit 3, owing to be welded by brazing between the hard alloy blocks 2 and the gap is full of cubond, copper has fabulous pliability can improve the piece that collapses that impact force causes, the phenomenon of fracture, can effectively the impact force buffering be decomposed, local impact force is reduced greatly, guarantee that welding hard alloy blocks 2 can not come off and rupture.
The glasses plate of said structure is owing to covered wearable hard alloy on its working surface, improved the wear resistance of plup inlet, can reduce concrete to the erosive wear of pan feeding inwall, guarantee the wear-resisting property of its inwall, make the glasses plate body form strong bonded to hard alloy abrasion-resistant layer by welding simultaneously, effectively support the shock resistance that has improved again glasses plate.
