Abstract
The utility model discloses a male die for broaching. The male die for the broaching comprises a male die (1) and a steel ball (2), wherein the steel ball (2) is fixedly connected with the head part of the male die. The male die for the broaching has the beneficial effects that by utilizing the steel ball at the head part of the male die, a damaged hole can be corrected, a pipe rivet can be flanged and riveted, the periphery of a loosened bolted pile can be impacted to reinforce the bolted pile, and the periphery of the hole can be impacted to reduce the caliber of the hole.
Description
Technical field
The utility model relates to field of machining, relates in particular to the rushing that a kind of reaming is used.
Background technology
At the industrial machinery manufacture field, often need to hole to sheet material, boring can cause the aperture to become large because wearing and tearing are out of shape in the sheet material use procedure, affects the normal use of sheet material.
The utility model content
The technical problems to be solved in the utility model is to hole in use because the wearing and tearing collision causes the boring distortion, and a kind of rushing of can reaming using is provided for this reason.
The technical solution of the utility model is: the rushing that a kind of reaming is used, it comprises rushing and is fixed in the steel ball of rushing head.
Steel ball described in such scheme is welded on the rushing head.
The beneficial effects of the utility model are to utilize the hole conformality of steel ball to damaging of rushing head, to pipe rivet flange riveter, impact around loosening deadman, and it is reinforced, and impact around the hole, dwindle bore.
