Abstract
The utility model discloses a standby cutting ring applied to a concrete pumping device, comprising a cutting ring (1). The cutting ring (1) is an integrally molded member, and made of GCr15 or GCr15SiMn. The cutting ring has sound wearing-resisting performance and high reliability; and the environment of component production is favorable.
Description
Technical field
The utility model relates to a kind of concrete pumping equipment cutting ring.
Background technique
Cutting ring is the strength member on the concrete pumping equipment distributing mechanism, belongs to easily damaged parts.The wear-resisting property of part is good, its faying surface the seal degree height, the performance of equipment is just secure.The cutting ring that present all concrete pumping equipment manufactories produce; its structure and technology are for taking faying surface edge alloy on the basis of bead-welding technology; this technology part manufacturing cost height; edge alloying technology condition makes the build-up wear-resistant decreased performance; the weakening of the protectiveness of wear-resisting weldering makes alloy easily come off in the use; poor reliability, and part manufacturing operation environment is poor.The wear resistance of cutting ring all dropping into to study how to improve structure and the technology that has part now, improves in each big manufacturer at present.
The model utility content
It is good that technical problem to be solved in the utility model provides a kind of wear-resisting property, good reliability, and the good concrete pumping equipment cutting ring of part manufacturing operation environment.
In order to solve the problems of the technologies described above, the concrete pumping equipment cutting ring that the utility model provides comprises cutting ring, and described cutting ring is a global formation spare, uses GCr15 or GCr15SiMn made.
Adopt the concrete pumping equipment cutting ring of technique scheme, cutting ring is taked whole alloy structure, integral quenching technology, and it is not wear-resisting fundamentally to have solved the wear-resisting weldering that prior art exists, alloy defective such as come off, and cost of production reduction, technology environmental protection.Adopt this cutting ring on concrete pumping equipment, the reliability of part, wear resistance, working life significantly improve, and special using effect on superpressure pump can fully show the potential of this technology.
In sum, the utility model is that a kind of wear-resisting property is good, good reliability, and the good concrete pumping equipment cutting ring of part manufacturing operation environment.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is original design of part schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, cutting ring 1 is a global formation spare, and cutting ring system is used GCr15 or GCr15SiMn made, and its process matched therewith can be guaranteed the part accuracy of manufacturing, guarantees integral quenching technology or the quenching technology for surfaces and the cover coat technology of part wear resistance; All face face intersections adopt the design of part of chamfering or rounding transition.
Referring to Fig. 2; original cutting ring 1 structure is build-up wear-resistant weldering 3 on the working surface of cutting ring 1; at faying surface edge alloy 2; this technology part manufacturing cost height; edge alloying technology condition makes the build-up wear-resistant decreased performance; the weakening of the protectiveness of wear-resisting weldering 3 makes alloy 2 easily come off in the use, poor reliability, and part manufacturing operation environment is poor.
Referring to Fig. 1, cutting ring 1 is taked whole alloy structure, uses GCr15 or GCr15SiMn made, integral quenching technology, the wear-resisting weldering that has fundamentally solved the prior art existence is not wear-resisting, defectives such as alloy comes off, have simple in structure, the technology environmental protection, relative cost is low, because material hardenability is better, quenching hardness height, the therefore working life of having improved part greatly.
Claims (1)
1, a kind of concrete pumping equipment cutting ring comprises cutting ring (1), it is characterized in that: described cutting ring (1) is a global formation spare, uses GCr15 or GCr15SiMn made.
