Description
Technical field
The present invention relates to the accessory that concrete conveying equipment is used, is glasses plate and the cutting ring of using on the concrete pump specifically.
Background technique
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 swinging when pump concrete 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 as shown in figures 1 and 3, be that a carbide ring 1 is formed wear-resisting plane by the cutting surface place that welding is embedded on the glasses plate matrix 2, and form one deck overlay cladding 3 with wear resistance electrode in its surface overlaying at the feeding hole inwall, to improve its wear-resisting property.Because overlay cladding 3 is low with respect to carbide ring 1 hardness, and thinner thickness, is subjected to concrete souring, still can produce wearing and tearing.Particularly in the course of the work, with cutting ring interaction partners concrete in stone when shearing, wearing and tearing can aggravation, shears the impact force that causes simultaneously and also easily the overlay cladding 3 of feeding hole oral area is cut and collapsed.After overlay cladding 3 damages, near the matrix 2 of glasses plate defeated material mouth will be worn very soon, near carbide ring 1 matrix 2 wearing and tearing owing to parcel defeated material mouth make its root exposed outside, very easily piece is fallen in carbide ring 1 cut-out when making shear action with cutting ring, the bridge of the nose position of glasses plate particularly, can fracture take place and fall the piece phenomenon, cause the glasses plate life-span to be fallen sharply.
Equally, existing hard alloy cutting ring, the cutting surface place that its structure such as Fig. 2 and shown in Figure 4, carbide ring 4 are embedded in cutting ring matrix 5 forms wear-resisting plane, and the inwall of cutting ring feeding hole and outer ring also form one deck overlay cladding 6 and 7 with the wear resistance electrode built-up welding.During pump concrete, cutting ring is swung along with the swing of S shape pipe, plays the concrete effect of cutting, so the speed of cutting ring wearing and tearing is also faster than glasses plate, and the concrete pressure in outlet port is high more, and the degree of wear of cutting ring is just serious more.Generally, the wearing and tearing of cutting ring at first occur in the edge, therefore can produce carbide ring 4 fractures at cutting ring material feeding mouth place and fall the piece phenomenon after overlay cladding 6 and 7 wearing and tearing.
Therefore, glasses plate and cutting ring adopt the mode at feeding hole inner wall overlaying wearing layer, though can improve its wear-resisting property to a certain extent, but carbide ring with respect to the cutting surface place, its wear-resisting property is still not satisfactory, its abrasion condition is still serious than the carbide ring at cutting surface place, and after overlay cladding damages, also can further influence the life-span of the reasonable carbide ring of relative wear resistance.For solve the above-mentioned deficiency that glasses plate and cutting ring adopt the built-up welding mode to bring in feeding hole, people begin to adopt the annulus of being made by cemented carbide equally to serve as a contrast at glasses plate and cutting ring matrix feeding hole inwall, to improve the wear-resisting property of feeding hole inwall.
Chinese patent literature CN2828383Y discloses a kind of wearing plate and cutting ring, and the structure of its wearing plate such as Fig. 5 and shown in Figure 7 are embedded in the discharge hole inwall of wearing plate matrix 8 and its wearing face with a L shaped all-in-one-piece carbide ring 9.The structure of its cutting ring such as Fig. 6 and shown in Figure 8 adopt a U-shaped whole hard alloy ring 11 to be embedded in discharge hole inwall, cutting surface and the surface, outer ring of cutting ring matrix 10.This whole hard alloy ring structure, not only make the surfaces easy to wear such as outer ring of discharge hole inwall, cutting surface and cutting ring of glasses plate and cutting ring be the cemented carbide material, improve wear-resisting property, and had the advantage of good integral strength, improved whole shock resistance.
But, this whole hard alloy ring structure that adopts among the CN2828383Y, section adopts L shaped (glasses plate) and U-shaped (cutting ring) structure, still has certain defective on preparation process.Mainly show:
At first, cemented carbide is different with the matrix expansion coefficient, cemented carbide is less than normal, adopt the whole hard alloy ring of L shaped or U-shaped cross section structure, after welding with matrix, because the contour projector difference of two kinds of materials, body portion will produce extrusion stress to carbide ring, after the welding cooling, very easily cause the cemented carbide ring opening, thereby can cause carbide ring to rupture, come off in the course of the work.
Secondly, adopt L shaped or U-shaped cross section structure whole hard alloy ring, increase with the matrix area of contact, when welding, can only weld along oral area edge, alloy hoop two ends, can't guarantee that inner surface of contact is full of solder flux, local phenomenon of leaking weldering can occur, carbide ring can not get effective support of matrix, when particularly cutting when work, can impact to carbide ring, cause breaking.
Chinese patent literature CN1454737A discloses the production method of a kind of glasses plate and cutting ring, be that carbide ring is cast on the steel billet body, the molten molten carbide ring that makes by metallic material under 1400 ℃～1600 ℃ high temperature is bonded on the steel billet body, improves the intensity that connects.Yet, this mode is because casting temperature is very high, and matrix and carbide ring are overall shrinkage, equally can be in cooling procedure because carbide ring is different with the thermal expansion coefficient of glasses plate matrix and cutting ring matrix, cause contraction rate and contour projector to have bigger difference, steel base can produce extrusion stress and the cemented carbide ring breakage occurs, come off equally carbide ring, and this process heat shrinks the infringement of extrusion stress even can surpass the integral solder of CN2828383Y.
Adopt the wearing layer premature damage that the built-up welding mode forms and then cause the carbide ring at cutting surface place impaired for solving discharge hole, Chinese patent literature CN2531129Y then discloses another solution, be to join end to end with the cemented carbide sector to cover matrix cutting surface place and form wear-resisting plane, the end to end side margin in sector both sides is a broken line; And adopt end to end horminess fastening gold bar block to be combined into annular in the matrix outer rim; The discharge hole inwall is joined end to end by cemented carbide Z type thin slice and is combined into annular.This mode makes the surface easy to wear of glasses plate and cutting ring equally all adopt cemented carbide to cover, and its overall wear resistance is good.But also there is following defective in this scheme:
(1) wear-resisting plane and discharge hole inwall, outer ring are to be combined into by difform plate, sheet, stick, its role is to make the plate, sheet, piece of different parts to adopt the cemented carbide of heterogeneity, to reduce cost.Yet this scheme building block is many and different, increased amount of finish undoubtedly, particularly for cemented carbide, be difficult to processing,, also increased the workload of processing and welding so in fact this mode has increased the difficulty of processing of product and the difficulty of welding.
(2) adopting Z type thin slice and edge is the sector of broken line, though can make between the adjacent sector and interlock between the adjacent Z type thin slice, and by making adjacent panels, butt joint between the sheet buckles, improving its sealing leaks from joint to prevent concrete mortar, but the problem that adopts the polyline shaped edge to bring is that not only difficulty of processing is big, at the bottom of the machining accuracy, be subjected to the influence of machining accuracy and assembly precision simultaneously, in fact be difficult to guarantee that the binding site between end to end sector and the Z type thin slice forms closely crowded closing, form leakage point in splicing place easily on the contrary and cause seal failure.
(3) because the bar blocks of Z type thin slice, the sector on the cutting surface and outer ring in its discharge hole is that individual components is welded on the matrix respectively, and between the adjacent Z type thin slice, between the adjacent sector, be to form occlusion structure together and make broken line shape splicing gap smaller as far as possible to reach sealing effect by jam-packed, splicing seams between end to end each parts does not have and can not weld, promptly only be welded to connect at the upper and lower edge of Z type thin slice and the inside and outside edge and the matrix of sector, cause the overall performance variation, low with high base strength.And in use, carbide alloy board in cutting surface place and discharge hole, it is different (during cuttings to the impact force of cutting surface place sector along the sector width direction) that sheet is subjected to force direction, local plate when being hit, sheet, the suffered impact force of stick all passes to the solder flux of weld, and owing to above-mentioned parts only weld at two ends, so very easily cause cemented carbide sector or Z type thin slice to come off, perhaps owing to weld the fracture that is hit because of leaking between Hardmetal materials and the matrix, thereby cause entire product to scrap, can reduce its working life on the contrary.
Summary of the invention
At above-mentioned defective, the present invention be devoted to glasses plate that delivering concrete is used and cutting ring overall wear resistance can and whole impact strength improve, to improve its working life.
Therefore, take all factors into consideration the wear resistance and the bulk strength problem of glasses plate, first purpose of the present invention is to provide a kind of glasses board for concrete pump, not only wear resistance is good, and the intensity height, so cemented carbide member be difficult for breaking and coming off, to improve the working life of product.
To achieve these goals, the present invention adopts following technological scheme: a kind of glasses board for concrete pump, comprise glasses plate matrix and the carbide ring that is contained on the matrix cutting surface, 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 glasses plate matrix 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.
Gap width between the adjacent hard alloy blocks is advisable with 1mm～3mm.
Second purpose of the present invention also is to provide a kind of concrete pump cutting ring, and not only wear resistance is good, and the intensity height, and cemented carbide member is difficult for breaking and coming off, to improve the working life of product.
In order to realize second purpose of the present invention, adopt following technological scheme: a kind of concrete pump cutting ring, comprise cutting ring matrix and the carbide ring that is contained on the cutting ring matrix cutting surface, 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 cutting ring matrix, in the feeding hole of cutting ring matrix, be combined into the cemented carbide annulus that is attached to the feeding hole inwall, in the cutting surface place of cutting ring matrix and feeding hole, leave straight line shape gap between the adjacent hard alloy blocks; The approximal surface of described hard alloy blocks and described cutting ring matrix welds together, and is full of solder flux in the straight line shape gap between the adjacent hard alloy blocks.
Even more ideal is that described hard alloy blocks outward edge can be turned back and be extended to the outer ring of described cutting ring matrix, forms the cemented carbide wear ring of the covering cutting ring matrix outer ring of annular.
Glasses board for concrete pump of the present invention and cutting ring, compare with prior art and to have following beneficial effect:
(1) cutting surface that reaches the feeding hole periphery in the feeding hole of glasses plate and cutting ring all adopts cemented carbide, and the cemented carbide area coverage is big, so the overall wear resistance of product is good.And owing to be to adopt a plurality of hard alloy blocks to be combined into, and leave the gap between the hard alloy blocks, the contraction buffer area when forming welding has avoided integral loop body material when welding to shrink the cemented carbide ring opening that the extruding carbide ring causes.
(2) because the cemented carbide wear parts is to adopt a plurality of hard alloy blocks to be welded into, not only descend the welding of edge, two ends thereon, also in the gap between adjacent hard alloy blocks by the welding between the filling flux reality hard alloy blocks, between hard alloy blocks and the matrix, welding is more abundant with respect to integral solder, guaranteed fully combining between cemented carbide member and the body material, and improved join strength, avoided welding insufficient direct impact that causes carbide ring.

Embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments, to help understanding content of the present invention.
Embodiment's 1 glasses plate
As Fig. 9 and shown in Figure 11, it is the structural representation of cemented carbide glasses plate of the present invention, comprise glasses plate matrix 14 and be inlaid in the carbide ring that matrix cutting surface place constitutes the wear-resisting plane of matrix, as seen from Figure 9, the carbide ring in the present embodiment is combined into by six hard alloy blocks 12 on hoop.
As shown in figure 11, the inward flange of every hard alloy blocks 12 turn 90 degrees in feeding hole along the hole wall folding at the feeding hole place of glasses plate matrix 14 and extends, form the cemented carbide annulus that covers the feeding hole inwall, constituted the wearing layer on the feeding hole inwall, improve the wear resistance of feeding hole, to reduce concrete erosive wear.This global sections as shown in figure 11 is L shaped hard alloy blocks 12, and no matter at glasses plate matrix cutting surface place or in feeding hole, all being formed with width between the adjacent hard alloy blocks 12 is the straight line shape gap 13 of L.The hard alloy blocks whole periphery that the linking limit of two ends and both sides is surrounded about in the of 12 all welds itself and glasses plate matrix 14 is welded together, by being full of solder flux in the straight line shape gap 13 that forms between the hard alloy blocks adjacent behind the alloy welding-on 12, not only adjacent hard alloy blocks is welded together and be combined into the domain, and hard alloy blocks 12 and matrix 14 are also welded together, and can prevent to cause leakage at gap location at this place.The alloy lining 15 that hard alloy blocks 12 and same welding-on are good is formed whole alloy wear-resisting plane.
This structure makes the cutting surface of glasses plate and the surface of inner hole wall constitute by cemented carbide, not only making the cross section of the alloy annular structure in aggregates of the alloy annulus of inwall and cutting surface is L shaped annulus, and be full of solder flux between the L shaped alloy block, both guaranteed the wear-resisting property of glasses plate, simultaneously because effective support and strong bonded that the glasses plate matrix partly forms cemented carbide, improved the glasses plate shock resistance again, the hard alloy blocks in L shaped cross section is stressed more reasonable under the effect of impact force and shearing force, make impact force be dispersed to whole alloy block, the stressed reduction of weld can not come off.For example cooperating with cutting ring when stone sheared, the impact force that glasses plate cutting surface edge is subjected to can pass to matrix with power by the part that L shaped cross section alloy block is positioned at feeding hole, and because the alloy block that hard alloy blocks is adjacent is welded together, cause whole carbide ring stressed, the impact force that the weld seam position is subjected on unit length reduces greatly, has guaranteed that alloy block can not come off and rupture.
Be understandable that,, can improve glasses plate matrix 14 and shrink the squeeze and destroy that causes carbide ring as long as form the gap between the adjacent hard alloy blocks.Yet gap too small being difficult for welds, and is not easy to guarantee welding quality.And excesssive gap causes overall wear resistance poor.Take all factors into consideration, the width L in gap 13 is advisable with 1mm～3mm.
Gap between the adjacent hard alloy blocks 12 is a straight line shape, not only be convenient to process, guarantee easily machining accuracy and assembly precision, and because weld seam is a straight weld, particularly under the unsuitable wide prerequisite in this gap, more help carrying out welding operation and guarantee welding quality, and polishing after the welding.
Be understandable that, if it is many more to form the hard alloy blocks of carbide ring, its anti-contraction deformation ability is good more, but too much words have not only increased the amount of finish of welding capacity and hard alloy blocks, because wear resistance is relatively poor relatively, the decline of overall wear resistance energy too much can be caused in the gap, therefore take all factors into consideration various factors, ideal with the 3-10 piece, can reach reasonable wear-resisting, shock resistance effect, and help the control of cost and quality.
Embodiment's 2 cutting ring
As Figure 13 and shown in Figure 14, be the cutting ring of the cemented carbide ring structure in a kind of L type cross section.Comprise that cutting ring matrix 21 and matrix cutting surface place constitute the carbide ring on the wear-resisting plane of matrix.Carbide ring is combined into by six hard alloy blocks 19 on hoop, hard alloy blocks 19 inward flanges are turned back along hole wall at the feeding hole place of cutting ring matrix 21 and are extended in feeding hole after 90 ° as shown in figure 14, make the cross section of hard alloy blocks 19 become the L type, wherein curved portion is combined into the cemented carbide annulus that is attached in the feeding hole, constitutes the wearing face of feeding hole.In cutting surface place and feeding hole, between adjacent hard alloy blocks, all form straight line shape gap 20, hard alloy blocks 19 weld together with whole approximal surface cutting ring matrix 21, the welding of promptly not only upper and lower edge, in the gap 20 that forms between the adjacent hard alloy blocks also the mode by the alloy welding-on be full of solder flux will, hard alloy blocks 19 welded together be combined into an integral body, form carbide ring on the cutting surface and in feeding hole, forming the wear-resisting annulus of cemented carbide, and with firmly welding of cutting ring matrix 21.This mode had both guaranteed that cemented carbide had the wear-resisting property that enough area coverages have improved cutting ring, simultaneously again since whole wear-resisting alloy block 19 stressed rationally, intensity is high, so also improved the cutting ring shock resistance.
As Figure 10 and shown in Figure 12, different with cutting ring shown in Figure 14 is, the outward edge of hard alloy blocks 16 is also turned back and is extended to the outer ring of cutting ring matrix 18 direction after 90 °, form the hard alloy blocks 16 in U type cross section like this, also form the cemented carbide wear ring of the covering cutting ring matrix outer ring of annular by welding in cutting ring matrix 18 outer rings.Owing to be full of cubond in the gap 17 between the hard alloy blocks 16, simultaneously with the carbide ring welding-on on the cutting surface of the feeding hole inwall of cutting ring and cutting ring, outer ring, form whole alloy wear-resisting plane.Thereby the cutting surface of cutting ring and inner hole wall, outer ring are covered by cemented carbide, not only make the alloy annulus of feeding hole inwall and the alloy hoop and the outer ring of cutting surface form an integrally-built U-loop, and be full of solder flux between the U-shaped alloy block, both guarantee the wear-resisting property of cutting ring, improved the whole shock resistance of cutting ring simultaneously again.Based on the reason identical,, guaranteed that hard alloy blocks can not come off or ruptures because of being subjected to impacting because its stressed reason is reasonable with glasses plate.
Based on embodiment 1 in same reason, be appreciated that, gap width T between the adjacent hard alloy blocks 16 and the gap width K between the adjacent hard alloy blocks 19 all are advisable with 1mm～3mm, the quantity of hard alloy blocks 16,19 is ideal with the 3-10 piece, and the size of hard alloy blocks is preferably consistent with shape.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
