Abstract
A novel wear-resistant elbow comprises an elbow and a wear-resistant layer in the elbow; the arc surface of the center line of the elbow is divided into an outer arc elbow (1) and an inner arc elbow (4); a group of grooves (2) for overlaying the wear-resistant layer are arranged on the inner wall of the outer arc elbow (1); the inner wall of the outer arc elbow (1) is an external wear-resistant layer which is made by the overlaying method, protrudes out of the inner wall and fills all the grooves (2); the outer arc elbow (1) and the inner arc elbow (4) are welded into one; an internal wear-resistant layer (3) which is made by the overlaying method and protrudes out of the inner wall is arranged in the inner arc elbow (4); and the depths of the grooves (2) are arranged symmetrically in accordance with the mode from increasing progressively to decreasing progressively, that is, the grooves (2) which are located in the middle of the elbow are the deepest, and the grooves (2) which are located at the both ends of the elbow are the shallowest. The novel wear-resistant elbow has the following advantages: the service life of the whole elbow is prolonged; and the slotted structure which is arranged symmetrically in accordance with the mode from increasing progressively to decreasing progressively can save wear-resistant alloy material, etc.
Description
Technical field
The utility model relates to a kind of novel wear resistant bend pipe.
Background technique
In modern industry, be in and carry the bend pipe working condition of particulate matter the most abominable, its degree of wear is quite serious.To use bend pipe to be example on the concrete pump, in order to prolong its working life, usually adopt following three kinds of methods: first method, adopt integral casting process, external arc side pipe wall is thickeied, can improve working life its deficiency: be limited to the influence of casting technique, material, applying working condition such as booster, significantly do not improve working life; Second method, adopt the insetting case technology of sleeve pipe, promptly at the wear-resistant grommet of the inside of plain end pipe edge cover, can prevent booster, its deficiency: but because edge cover is subjected to the restriction of bend pipe deadweight for foundry goods or pottery and foundry goods, the antiwear property of foundry goods edge cover is also relatively limited, the fragility and the connectivity thereof of pottery edge cover have determined that also it is cracked easily, have peeled off, and complex manufacturing technology.The third mode; adopt the technology of built-up welding; be about to general elbow and split in two, behind the build-up wear-resistant alloy, two halves are docked along its axis; its deficiency: be subjected to the abrasion resistance alloy self character; limited as its built-up welding thickness of wear-resisting more material, piled the influence of peeling off easily thick, be difficult to accomplish the reinforcement protection of external circular arc side; the butt joint of two halves just in time is in the zone that needs to strengthen protection, improves and also makes a discount widely working life.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of structure to divide more rationally, can effectively improve the novel wear resistant bend pipe in working life.
The purpose of this utility model is achieved by following technical proposals: comprise bend pipe and inner wearing layer thereof; Described bend pipe is divided into external arc bend pipe and interior circular arc bend pipe on the arc surface of heart line therein; One group of groove that is used for the build-up wear-resistant layer is set on the inwall of described external arc bend pipe; The inwall of described external arc bend pipe is that make in the built-up welding mode, that give prominence to its inwall, the fluted outside wearing layer of filling; Described external arc bend pipe and interior circular arc bend pipe are welded into one.
Inboard wearing layer for making in the built-up welding mode, give prominence to its inwall in the circular arc bend pipe in described.
The degree of depth of described groove is according to being incremented to the mode symmetric arrangement of successively decreasing, and it is the darkest promptly to be positioned at the middle groove of bend pipe, and the groove that is positioned at the bend pipe two ends is the most shallow.
Compared with prior art, the utlity model has and improve the bend pipe whole service life, be incremented to the mode symmetric arrangement notching construction that successively decreases and save advantages such as wear resistant alloy material.
Description of drawings
Accompanying drawing 1 is the utility model one embodiment's organigram;
Among the figure: 1-external arc bend pipe, 2-groove, the inboard wearing layer of 3-, circular arc bend pipe in the 4-.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to accompanying drawing, the utility model comprises bend pipe and inner wearing layer thereof; Described bend pipe is divided into external arc bend pipe 1 and interior circular arc bend pipe 4 on the arc surface of heart line therein; One group of groove 2 that is used for the build-up wear-resistant layer is set on the inwall of described external arc bend pipe 1; The inwall of described external arc bend pipe 1 is outside wearing layer its inwall that make in the built-up welding mode, outstanding, filling fluted 2; Described external arc bend pipe 1 and interior circular arc bend pipe 4 are welded into one.
Inboard wearing layer 3 for making in the built-up welding mode, give prominence to its inwall in the circular arc bend pipe 4 in described.
The degree of depth of described groove 2 is according to being incremented to the mode symmetric arrangement of successively decreasing, and it is the darkest promptly to be positioned at the middle groove 2 of bend pipe, and the groove 2 that is positioned at the bend pipe two ends is the most shallow.
Embodiment:
Casting external arc bend pipe 1, material is ZG35, and the inwall of external arc bend pipe 1 is provided with one group of groove 2, and middle groove 2 groove depth 10mm shoal the groove 2 groove depth 5mm at two ends gradually toward two ends.Outside wearing layer covers the inwall of external arc bend pipe 1 in the built-up welding mode, that is: it is fluted 2 that outside wearing layer is filled institute, and the about 2mm of the inner wall surface of outstanding external arc bend pipe 1 is thick.
Circular arc bend pipe 4 in the casting, material is ZG35, the inwall of interior circular arc bend pipe 4 is normal.Be the thick inboard wearing layer 3 of the about 2mm of its inwall that make in the built-up welding mode, outstanding in the interior circular arc bend pipe 4.
In the present embodiment, described outside wearing layer and inboard wearing layer 3 adopt the welding rod built-up welding of abrasion resistance alloy V-150 to form.
External arc bend pipe 1 that built-up welding is good and interior circular arc bend pipe 4 connect weldering and form a complete bend pipe.
The utility model is bend pipe to be divided into the method for two parts and the third method of prior art has tangible difference, groove lug, nib in the external arc bend pipe can improve intensity, overlay cladding in the groove can with external arc bend pipe good binding, and the weld seam after synthetic is not to be positioned at the worst position of wearing and tearing, this structural division is more scientific and reasonable, the outside wearing layer of worst external arc bend pipe 1 inner wall overlaying is thicker, can improve the working life of bend pipe significantly.
