Abstract
The utility model discloses a WC coating-reinforced asphalt concrete road surface milling-planing cutter and relates to a cutting tool used in asphalt concrete road surface maintenance. Aiming to prolong the service life of the existing asphalt concrete road surface milling-planing cutter, the utility model provides a set of the cutter structure and a processing and fabricating method thereof. The cutter structure adopts a hard alloy cutter head and an alloy structural steel cutter body; the cutter body is processed and fabricated through die forging technique which maintains the complete forging streamline, and the cutter body is processed with heat treatment to obtain high strength; the cutter head and the cutter body are connected through high-intensity braze welding; and a WC coating is sprayed on the outer surface of the cutter body to improve the wear resistance of the surface during the cutting process. The WC coating-reinforced asphalt concrete road surface milling-planing cutter is simple in process, low in cost, economic and practical, and is particularly suitable to be used in the production of an enterprise of matching tools of a road surface construction machine.
Description
Technical field
The utility model relates to a kind of asphalt concrete pavement milling cutter.
Background technology
Along with the increase of maintenance of surface amount with to the raising of maintenance construction rate request, advanced maintenance of surface technology constantly is used, and the asphalt concrete pavement milling machine has maintenance of surface operation high-quality and high efficiency remarkable characteristic.With in the past plant or manually carry out similar operation relatively, this equipment have short construction period, operating efficiency height, good engineering quality, constructing operation flexible, reduce distinguishing feature such as constructor's labour intensity.Asphalt concrete pavement milling cutter is that road-surface milling machinery is finished the employed extraordinary cutting tool of road surface operation.The quality of its performance and the length in life-span, and the height of manufacturing cost all are directly connected to the market price of cutter, and then have influence on the production efficiency and the economic benefit of maintenance of surface construction enterprises.
Summary of the invention
Overcome the shortcoming that the tool wear of asphalt concrete pavement milling in the past is fast, the life-span is short, the utility model has adopted a kind of new asphalt concrete pavement milling cutter manufacturing and reinforcement scheme.Adopt the scheme of cutter head cutter hub high strength soldering connection, the whole die-forging forming of cutter hub, cutter hub surface spraying abrasion-proof layer, improved the abrasion resistance of cutter hub, prolong road-surface milling cutter life.
Description of drawings
Fig. 1 is that the utility model WC coating is strengthened asphalt concrete pavement milling cutter structure schematic diagram.
WC coating shown in Figure 1 is strengthened the asphalt concrete pavement milling cutter and is made up of cutter head (1), cutter hub (2) two large divisions, and two parts are by soldered seam (3) connect, cutter hub (2) be cut ground surface material contact portion surface WC coating (4) arranged.
The specific embodiment
The utility model relates to a kind of asphalt concrete pavement milling cutter, comprises weld seam (3) between cutter head (1), cutter hub (2), cutter head and cutter hub and (4) four parts of coating on cutter hub surface on the structure.The failure conditions of road-surface milling cutter is found in the past by analysis, failure mode mainly comes off based on cutter head and the cutter hub wearing and tearing, the utility model is raising asphalt concrete pavement milling cutter life, and the main key technology that adopts is improving cutter head cutter hub bonding strength and raising cutter hub abrasion resistance.Cutter head (1) and cutter hub (2) material are selected and processing method: cutter head (1) needs high rigidity and high-wearing feature to adopt the YG8 Hardmetal materials, cutter hub (2) adopts the structural alloy steel die-forging forming, owing to keeping continuous forging flow lines, can guarantee to obtain enough intensity through heat treatment again.Be connected with cutter hub (2) high strength for reaching cutter head (1), existing asphalt concrete pavement milling cutter cutter head and cutter hub soldered seam (3) often use H62 or H59 to be solder, bonding strength is low often to cause cutter head to come off, the utility model uses 105 solders, for reducing soldering heating tool setting soma and Effect on Performance, the utility model mode of heating when soldering adopts eddy-current heating, guarantees not reduce through cutter hub intensity in brazing process of heat treatment reinforcement when obtaining high strength of brazed joint.For further improving the abrasion resistance on cutter hub (2) surface, employing with cutter hub (2) surface spraying one deck WC coating, utilizes the superelevation abrasion resistance of WC coating (4) after cutter head (1) and cutter hub (2) soldering are finished, delay the cutter hub wearing and tearing, the application life of improving asphalt concrete pavement milling cutter.
Claims (1)
1. a WC coating is strengthened asphalt concrete pavement milling cutter, it is characterized in that carbide bit and structural alloy steel die-forging forming cutter hub adopt the high strength soldering to be connected, cutter hub external surface spraying WC wear-resistant coating.
