Description
Technical field
The present invention relates to the accessory of concrete conveying equipment, relate to the glasses plate on concrete pump and manufacture method specifically.
Background technique
Glasses plate is used to the port protecting 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 glasses plate and cutting ring interacts; to mixed earth stone when shearing; because hard alloy abrasion-resistant layer does not have disperses impact forces; carbide ring is caused to collapse block;, fracture can be there is and fall fast phenomenon, causing glasses plate not high for working life in the particularly bridge of the nose position of glasses plate.
Prior art forms hard alloy abrasion-resistant layer by overall built-up welding, but build-up wear-resistant layer is relative to hard alloy blocks, its wear-resisting property and hardness not satisfactory, especially to mixed earth stone when shearing, easily cause and burst apart, working life is lower.Adopt the method for whole hard alloy ring, whole hard alloy ring improves wear resistance and the impact of glasses plate working surface, but add man-hour can the thermal expansion of carbide ring and glasses plate body and shrinkage coefficient different and cause carbide ring to burst apart, when stone is sheared, not effective buffering causes fracture.
Summary of the invention
For solving above-mentioned prior art Problems existing, 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 working surface thereof, welding hard alloy blocks in described hard alloy abrasion-resistant layer, the cooperation gap between described hard alloy blocks is Y-shaped gap, is full of solder flux in described Y-shaped gap.The quantity of described hard alloy blocks is 2 ~ 8 pieces.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 gap is 0.1 ~ 3mm near the clearance D of pan feeding nose end.Described Y-shaped slot edge wire clamp angle is 10 ~ 80 degree.Described Y-shaped gap is at the parallel straight section of its to be a length near plup inlet place be L, and length L is 1 ~ 3mm.
The present invention's second object is also, there is provided a kind of making method of Y-shaped Anti-wear wear plate, 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 glasses plate body with plain carbon steel, machined grooves on its working surface; 2. add brazing powder in the groove on 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, pan feeding hole wall wearing layer is formed with a carbide electrode built-up welding, make hard alloy blocks surface rubescent hard alloy blocks homogeneous heating on pan feeding hole wall wearing layer and working surface with welding gun, then by welding gun, copper arc welding electrode is melted in copper water inflow Y-shaped gap; 4., after the copper water condensation in Y-shaped gap, again with welding gun, glasses plate body welding gap place is heated, copper water is melted.5. after glasses plate body naturally cools under normal temperature state, then polished and then formed product in welding part.
The invention has the beneficial effects as follows:
(1) hard alloy abrasion-resistant layer is adopted can to improve the overall wear resistance energy of glasses plate and the hardness of working surface.
(2) form adopting the welding of hard alloy blocks phase to connect, when avoiding the welding of integrated type hard alloy layer, bulk material dilation coefficient is different causes extruding cemented carbide layer, causes hard alloy layer to ftracture.
(3) because hard alloy layer has hard alloy blocks to be spliced, and stitching portion becomes Y-shaped gap, it coordinates gap to be full of cubond, so glasses plate and cutting ring interact to mixed earth stone when shearing, form an interim damping of shocks district, rigid impact can not be caused 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 working surface thereof, welding hard alloy blocks 2 in described hard alloy abrasion-resistant layer, cooperation gap between described hard alloy blocks 2 is Y-shaped gap 3, is full of solder flux in described Y-shaped gap 3.The quantity of described hard alloy blocks 2 is 4 pieces.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 gap 3 is 1mm near the clearance D of pan feeding nose end.Described Y-shaped gap 3 edge line angle is 30 degree.Described Y-shaped gap 3 is at the parallel straight section of its to be a length near plup inlet place be L, and length L is 2mm.
Gap between hard alloy blocks 2 becomes Y-shaped gap 3 and is filled with 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 ensure hard alloy abrasion-resistant layer in gap.When shearing stone, the impact force that glasses plate cutting surface edge is subject to can be delivered to glasses plate body by Y-shaped gap 3 dispersion, owing to be welded by brazing between hard alloy blocks 2 and gap is full of cubond, what copper had that fabulous pliability can improve that impact force causes collapses block, the phenomenon of fracture, effectively impact force buffering can be decomposed, the impact force of local is reduced greatly, ensure that welding hard alloy blocks 2 can not come off and rupture.
The glasses plate of said structure is due to its working surface covering wearable hard alloy, improve the wear resistance of plup inlet, the erosive wear of concrete to pan feeding inwall can be reduced, ensure the wear-resisting property of its inwall, make glasses plate body define strong bonded to hard alloy abrasion-resistant layer by welding simultaneously, effectively support the shock resistance turn improving glasses plate.
The manufacture method of Y-shaped Anti-wear wear plate of the present invention, its process step comprises: 1. process glasses plate body 1 with plain carbon steel, machined grooves on its working surface; 2. add brazing powder in the groove on glasses plate body 1, hard alloy blocks (2) is combined into annular along the groove of eye slab body 1; 3. at two pan feeding hole walls of glasses plate body 1, pan feeding hole wall wearing layer is formed with a carbide electrode built-up welding, make hard alloy blocks 2 surface rubescent hard alloy blocks 2 homogeneous heating on pan feeding hole wall wearing layer and working surface with welding gun, then by welding gun, copper arc welding electrode is melted in copper water inflow Y-shaped gap 3; 4. after the copper water condensation in Y-shaped gap 3, again with welding gun, gap place is welded to glasses plate body 1 and heat, copper water is melted.5. after glasses plate body 1 naturally cools under normal temperature state, then polished and then formed product in welding part.
