Abstract
The utility model discloses a novel cemented carbide broach. The novel cemented carbide broach comprises a broach handle (1) and a broach body (2) which is disposed on the broach handle (1). The broach body (2) is shaped like a rectangular cylinder. A cylindrical surface of the broach body (2) is equipped with multiple cemented carbide blades (3) from one end to the other end of the broach body (2). A space between each two adjacent cemented carbide blades (3) is identical. The cemented carbide blades (3) successively increase in terms of height from one end to the other end of the broach body (2). The front angle of each cemented carbide blade (3) is 9 to 13 degrees, and the inclination angle of each cemented carbide blade (3) is 6 to 11 degrees. The broach handle (1) is cone-shaped. The beneficial effects of the utility model are that the novel cemented carbide broach is simple in structure, stable in broaching, high in broaching intensity and high in broaching efficiency, enables roughness of products after broaching to be effectively reduced, and enables products to be formed once through broaching.
Description
Technical field
The utility model relates to broaching automobile primary bearing (ball) cover end face broaching tool, particularly a kind of novel hard alloy broaching tool.
Background technology
At present, development along with auto industry, the demand of auto parts and components is increasing, the surface roughness of the most of parts on automobile all requires the very low of processing, especially the roughness of the main beating cap end face of automobile engine all requires to be up to state standards conventionally, because automobile engine is absolutely necessary as automobile core, and in automobile engine, need to be fixed on cylinder for sealing air cylinder by the end face of main beating cap, prevent extraneous dust, particle enters in cylinder, thereby play the effect of protection cylinder, therefore, it is very low that the roughness of the end face of main beating cap is done conventionally.Prior art is monoblock type high-speed steel broach for the broaching tool of main bearing end cover processing, although this high-speed steel broach has the relatively simple advantage of the manufacturing procedure of manufacture, but the material of the main bearing end cover that automobile is used is spheroidal graphite cast-iron, need in layer machined surface be excised, and all needing tool setting again after every cutting layer of metal, the roughness of the main bearing end cover end face after broaching is greatly, operation is very inconvenient, broaching efficiency is extremely low.In addition, also have that broaching tool wearing and tearing are large, broaching not steadily, service life short shortcoming.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, broaching steadily, broaching intensity is high, the roughness that can effectively reduce broaching rear min bearing end face, Broaching forming, the high novel hard alloy broaching tool of broaching efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel hard alloy broaching tool, it comprises handle of a knife and cutter hub, described cutter hub is arranged on handle of a knife, the rectangular column of cutter hub, on the cylinder of described cutter hub and along cutter hub one end to the cutter hub other end, be provided with many row's carbide chips, the spacing of every row's carbide chip equates, the other end of the height of every row's carbide chip from one end of cutter hub to cutter hub increases successively, 9 ~ 13 ° of the anterior angles of carbide chip, the inclination angle of carbide chip is 6 ~ 11 °.
The tapered shape of described handle of a knife.
The top of the height of the every row's carbide chip on described cutter hub from the tail end of cutter hub to cutter hub increases successively.
The anterior angle of described carbide chip is 10 °, and the inclination angle of carbide chip is 8 °.
The utlity model has following advantage: on the cylinder of (1) cutter hub of the present utility model and along cutter hub one end to the cutter hub other end, be provided with many row's carbide chips, the spacing of every row's carbide chip equates, the other end of the height of every row's carbide chip from one end of cutter hub to cutter hub increases successively, only need make that row's carbide chip of blade height minimum and the end face of bearing (ball) cover to a cutter, then pull this broaching tool, the value of the roughness of the main bearing end cover end face that can process is very little.(2) this uses 9 ~ 13 ° of the anterior angles of novel carbide chip, and the inclination angle of carbide chip is 6 ~ 11 °, broaching tool when broaching main bearing end cover, make cutting metal more steadily, broaching intensity is higher, extended broaching tool service life.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
In figure, 1-handle of a knife, 2-cutter hub, 3-carbide chip.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, a kind of novel hard alloy broaching tool, it comprises handle of a knife 1 and cutter hub 2, described cutter hub 2 is arranged on handle of a knife 1, the rectangular column of cutter hub 2.As depicted in figs. 1 and 2, on the cylinder of cutter hub 2 and along cutter hub 2 one end to cutter hub 2 other ends, be provided with many row's carbide chips 3, the spacing of every row's carbide chip 3 equates, the other end of the height of every row's carbide chip 3 from one end of cutter hub 2 to cutter hub 2 increases successively, 10 ° of the anterior angles of carbide chip 3, the inclination angle of carbide chip 3 is 8 °, and broaching tool is in broaching during main bearing end cover, make cutting metal more steadily, higher, the broaching tool long service life of broaching intensity.
As depicted in figs. 1 and 2, the tapered shape of handle of a knife 1, as shown in Figure 2, the top of the height of the every row's carbide chip 3 on cutter hub 2 from the tail end of cutter hub 2 to cutter hub 2 increases successively, therefore, only need make that row's carbide chip 3 of blade height minimum and the end face of bearing (ball) cover to a cutter, then pull this broaching tool, the value of the roughness of the main bearing end cover end face that can process is very little.
