Abstract
The utility model discloses a wearable plate with sintered hard alloy structure on inner wall surface of discharge hole for solving the problems of the high cost and the matched abradability between the main working surface and the secondary working surface of a wear plate. The wear plate comprises a basal body comprising the main working surface and the secondary working surface which is a wearing coat on the inside wall of a discharge hole. The secondary working surface comprises hard alloy basic pieces assembled together. The service life of the wear plate is prolonged because the wearing coat composed of hard alloy basic pieces is arranged on the inside wall of the discharge hole; the abrasion resistance of the wearing coat is matched with the abrasion resistance of the main working surface thereof. The low hard alloy can be selected for the material of the wearing coat on the secondary working surface. The price is relatively cheap. The processing of the basic pieces is easy. The cost of the basic pieces is reduced compared to the hard alloy integral ring. A plurality of kinds of hard alloy basic pieces can constitute the inside walls of the discharge holes of the wear plates of the different diameter and the different shape. Various wear plates can be made. The utility model has the advantages of extensive adaptability, flexibility and multiple uses.
Description
Technical field: it is the concrete pump accessory that the utility model relates to a kind of building machinery.
The requirement in background technique: along with the development of concrete pump, for easily damaged parts wherein---wearing plate working life, more and more higher.Wish the wearing plate more wear-resisting, that life cycle is longer to occur.
At present, used cemented carbide on the groundwork surface of wearing plate.Because the Hardmetal materials excellent abrasive has improved the wear resistance on wearing plate groundwork surface greatly.Thereby be greatly enhanced its working life.
For the underwork surface of wearing plate, Mo Sun degree will be lower than the groundwork surface of wearing plate at work.Most engineers and technicians adopt the method for build-up wear-resistant welding rod; Perhaps the other engineers and technicians adopt the method for tungsten carbide button's domain, improve its wear resistance.
For the former, because therefore the wear resistance of wear resistance electrode overlay cladding will unmatched phenomenon just occur well below the lip-deep cemented carbide wear resistance of wearing plate groundwork.That is to say that the time that inefficacy occurs has been postponed greatly owing to adopted Hardmetal materials in the groundwork surface of wearing plate.The position of like this, at first occur losing efficacy has just occurred on the underwork surface of wearing plate.Overlay cladding is worn very soon, exposes matrix gradually, and wearing and tearing this moment can be more serious, causes the enlarged diameter of discharge hole, and the lip-deep hard alloy layer of groundwork comes off, thereby whole wearing plate lost efficacy.
For the latter, mainly appear on the wearing plate of Japanese some concrete pumps that produce.They are tungsten carbide button's domain on the discharge hole inwall of wearing plate.Because cemented carbide is hard and crisp material, this ring just can not be processed very thinly, and certain thickness must be arranged, and this has just caused the waste of cemented carbide; In order to inlay, this ring also will be worked into certain dimensional accuracy, and the processing charges of cemented carbide is very expensive.This shows that such wearing plate is very expensive economically.
Summary of the invention: the utility model purpose is the wear resistance that can solve the groundwork surface of wearing plate and the underwork surface problem that is complementary, and a kind of wearing plate with low cost can be provided again.
The wearing plate that the utility model provides, comprise the wearing plate matrix that has discharge hole on it, matrix groundwork surface and underwork surface are the wearing layer on the discharge hole inwall, it is characterized in that the underwork surface is that the discharge hole inwall is tiled by the carbide matrix this film and forms.
The carbide matrix this film, its thickness the best is 1-3mm, be shaped as " rectangle ", " trapezoidal ", " rhombus ", " parallelogram ", " triangle ", " Z type ", " T type ", and can be combined into " polygonal " of complete of wearing plate discharge hole inwall.Slit between the basic sheet all is not parallel to the center line of discharge hole, just can form firm hard alloy abrasion-resistant layer by high temperature sintering or welding.
The utility model advantage: 1. owing on the inwall of wearing plate discharge hole, adopt the carbide matrix this film to form wearing layer, on wear-resisting property, be complementary, prolonged the working life of wearing plate greatly with the lip-deep hard alloy abrasion-resistant layer of its groundwork.2. the carbide matrix this film can hang down than the lip-deep cemented carbide of groundwork on material owing to use on the underwork surface of wearing plate, and price is relatively cheap.These basic sheet easy processings, cost will reduce with respect to the cemented carbide domain greatly.3. several carbide matrix this films can be formed different-diameter, difform wearing plate discharge hole inwall, can make various wearing plates, very wide, flexible, the many usefulness of adaptability.

Fig. 2, several difform carbide matrix this film schematic representation.
Embodiment:
Embodiment 1
As shown in Figure 1, this wearing plate comprises the wearing plate matrix 1 that has discharge hole on it, wants working surface secondarily---form wearing layer with carbide matrix this film " Z matrix " 4 on the inwall of discharge hole 2.The basic sheet of cemented carbide can be done very thinly, and it is thick to make 1-3mm as required.This wearing layer also can be formed by basic sheet 5 interlaced the tiling of the two above rectangles of row, can reach the effect of " Z matrix " 4 equally.What need particularly point out is that slit between the basic sheet all is not parallel to the center line of discharge hole (partial parallel is passable; Otherwise identical with the direction that concrete flows, will wash away seriously, this slit can be strengthened very soon).
Cemented carbide on the groundwork surface 3 of wearing plate except the requirement of wear resistance, also will be considered impact resistance aspect material, the material of carbide matrix this film considers mainly that then wear resistance gets final product, and is therefore, comparatively economical.
Embodiment 2
On wearing plate underwork surface---can also use " trapezoidal 6 ", " rhombus ", " parallelogram 7 ", " triangle 8 ", " T type 9 " on the inwall of discharge hole 2, and " polygonal " that can be combined into complete of wearing plate discharge hole inwall tiles composition.In a word, every can piece together full wearing plate discharge hole inwall, and reduce the slit as far as possible, simultaneously making again that the shape of the center line of discharge hole is avoided being parallel to fully in this slit can.
The carbide matrix this film manufactures and is easy to, and the expense of processing is much lower with respect to the cemented carbide domain; And the carbide matrix this film can also form the wearing plate discharge hole inwall of different-diameter, and to adapt to different wearing plates, just as building a wall, the shape of brick is very simple, but it can be built into various walls.
