Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] like Figure 2 to Figure 5 As shown, a device for mechanical extrusion flaring provided by the present invention includes a clamp body 1, a handle 2, a replaceable anvil 3, a bush 4, a hexagonal threaded sleeve 5, a drive screw 6 and a dial pin 7, Wherein, the clip body 1 is a bow-shaped structure, and the upper side wall of the opening end of the clip body 1 is provided with a first installation hole, and the axis of the first installation hole is perpendicular to the axis of the upper side wall of the clip body 1; A hexagonal threaded sleeve 5 is installed in the first mounting hole, and a drive screw 6 is fitted in the hexagonal threaded sleeve 5 .

[0043] like Image 6 As shown, the hexagonal threaded sleeve 5 is a three-step stepped shaft structure, which are respectively the first stepped shaft, the second stepped shaft and the third stepped s...

Abstract

The invention provides a device used for mechanical extrusion type flaring. The device comprises a clamp body, a replaceable anvil, a hexagonal thread sleeve, a transmission screw rod and a moving pin. The clamp body is of an arch structure, a first mounting hole is formed in the upper side wall of the open end of the clamp body, the axis of the first mounting hole is perpendicular to the axis ofthe upper side wall of the clamp body, the transmission screw rod is assembled in the first mounting hole, the moving pin is mounted at one end of the transmission screw rod, the replaceable anvil ismounted at the other end of the transmission screw rod, the free end of the replaceable anvil is a work part, the work part is of a cone structure, the taper of the cone structure is matched with thetaper of a combustion chamber casing conical hole, it is clearly ensured that during flaring of a bypass air guide pipe mounting base, stress is uniform, damage is avoided, and rapid and efficient deforming is achieved. The flaring of a mounting base, a supporting plate self-locking nut, a bush and the like required to be assembled in a multi-model combustion chamber casing assembly can be achieved.

Description

technical field [0001] The invention belongs to the riveting assembly technology of engine components, and relates to a device for mechanical extrusion flaring. Background technique [0002] When assembling an engine, it is necessary to rivet the flare of the bypass bleed air pipe mounting seat to the combustion chamber casing. It is necessary to ensure that the end face of the flaring is not allowed to exceed the front wall, and use a 10 times magnifying glass to check that there is no crack at the riveting part after flaring. [0003] When the existing device expands, it is placed on the fitter's table, the casing and the supporting plate nut to be expanded are supported by a special bracket, and then the special punch is placed on the reaming nut, and the special punch is hit with a hammer. Punch to deform it into the desired shape. [0004] However, this method seems simple, but it is easy to be uncontrollable in force, causing damage to the flared mouth, cracks, or po...
