Abstract
The utility model relates to a tool with a ribbed tool body for pavement machinery, which belongs to the metal material technical field. The tool with the ribbed tool body for the pavement machinery comprises a tool body and a tool tip, and the tool tip is welded on the tool body. The tool is characterized in that the front part of the tool body is provided with a ribbed wear-resistant layer, and the tool tip is welded on the tool body (1). The tool has the advantages of simple process method, small investment on processing equipment, unique and novel structural form and so on, and effectively solves the uneven abrasion problem of a milling tool, thereby improving the quality, the service life and the production efficiency of the tool.
Description
Technical field
The utility model belongs to the metal material technical field, particularly relates to the cutter that a kind of pavement construction machinery cutter hub has rib.
Background technology
At present, in actual applications, employed road surface cold milling and planing machine cutter is seting welding carbide point of a knife and making on the low-alloy steel matrix all.The matrix front portion is a truncated cone-shaped.Because the applying working condition of cutter is very complicated and abominable, the variation of stone, pitch, cinder and the milling degree of depth of for example various cement and different proportion and size etc., in construction, always there is a certain proportion of cutter to be stuck in the tool magazine and can not to rotate, thereby the eccentric wear of cutter takes place even cause the bending of cutter hub, directly influenced the quality of cutter and the production efficiency of application life and complete machine.
Summary of the invention
The technical problem of the utility model for existing in the solution known technology, and provide a kind of pavement construction machinery cutter hub that the cutter of rib is arranged.
The purpose of this utility model provides a kind of improved rib milling cutter that has, and it can solve the eccentric wear problem of milling cutter effectively, thereby improves quality and the application life and the production efficiency of cutter.
The utility model is taked following technical scheme:
The pavement construction machinery cutter hub has the cutter of rib, comprises cutter hub, point of a knife, and the point of a knife welding-on is on cutter hub.Be characterized in: cutter hub is anterior for the rib wearing layer is arranged, and the point of a knife welding-on is on cutter hub 1.
The utility model can also adopt following technical measures:
Described pavement construction machinery cutter hub has the cutter of rib, is characterized in: the matrix that rib wearing layer and cutter hub are arranged of cutter hub is a metallurgical binding.
Described pavement construction machinery cutter hub has the cutter of rib, is characterized in: the rib wearing layer that has of cutter hub is positioned at the front portion of cutter hub.
Described pavement construction machinery cutter hub has the cutter of rib, is characterized in: the rib number that the rib wearing layer is arranged is 4～10.
Described pavement construction machinery cutter hub has the cutter of rib, is characterized in: the height on rib top is 1.0～4.0mm, and width is 1.5～6.0mm, long 6.0～15.0mm.
Advantage that the utlity model has and good effect:
The pavement construction machinery cutter hub has the cutter of rib owing to adopted technical solutions of the utility model, and a kind of improved rib milling cutter that has is provided, and it can solve the eccentric wear problem of milling cutter effectively, thereby improves quality and the application life and the production efficiency of cutter.There is the contour structures of rib the front portion of cutter hub, makes cutter when the milling operation, has increased the rotating torque of cutter, than the easier rotation of circular cutter, and can not be stuck in the bending that causes eccentric wear in the tool magazine even produce cutter hub, has improved production efficiency greatly.
It is simple to the utlity model has process, process equipment small investment, advantages such as form of structure uniqueness, novelty.Manual operations can be finished.
Description of drawings
Fig. 1 is the cutter structure schematic diagram that the utility model pavement construction machinery cutter hub has rib;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure, 1-cutter hub, 2-have the rib wearing layer, 3-point of a knife, 4-rib.
The specific embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1 and Fig. 2.
Embodiment 1
The pavement construction machinery cutter hub has the cutter of rib, comprises cutter hub, point of a knife, and for rib wearing layer 4 and 2 are arranged, point of a knife 3 welding-ons are on cutter hub 1 on its cutter hub 1.Cutter hub 1 have rib wearing layer 4 and 2 and the matrix of cutter hub 1 be metallurgical binding.The rib wearing layer 4 and 2 that has of cutter hub 1 is positioned at the front portion of cutter hub 1.The rib number is 6.
The height on this cutter rib top is 2.5mm, and width is 3.5mm, long 10.5mm.Cutter hub 1 material is a low-alloy steel, and reinforced wear-resistant layer 2 and rib 4 are high-abrasive material, and point of a knife 3 is a carbide alloy.
Claims (5)
1. a pavement construction machinery cutter hub has the cutter of rib, comprises cutter hub, point of a knife, it is characterized in that: cutter hub (1) is gone up to rib wearing layer (4) and (2) are arranged, and point of a knife (3) welding-on is on cutter hub (1).
