Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the multi-purpose cross wedge rolling die of the present invention will be further described;

[0010] Depend on figure 1 , figure 2 It can be seen that a cross wedge rolling die of the present invention includes upper and lower die bodies 1, and the upper and lower die bodies 1 are composed of several modules, and each module is movably installed on the upper and lower sides of the cross wedge rolling mill. on work roll 2.

[0011] When the present invention is used, the number of modules of the upper and lower mold bodies 1 is determined according to the actual size of the shaft parts to be processed, and then each module is installed on the upper and lower work rolls 2 of the cross wedge rolling mill to form a complete The upper and lower mold bodies 1 can produce shafts of different sizes.

[0012] The technology of this embodiment is mainly solved by the following technical solutions: the replaceable parts of the ...

Abstract

The invention discloses a multipurpose cross wedge rolling die. The multipurpose cross wedge rolling die comprises an upper die body and a lower die body. The upper die body and the lower die body are respectively composed of a plurality of modules. The modules are movably installed on an upper working roll and a lower working roll of a cross wedge rolling machine. Hole pattern sizes of the die can be determined according to the actual sizes of machined products, namely, hole patterns of a new die are designed according to changed modules of shaft parts to be machined and an original die, and the shaft parts to be machined are produced. The multipurpose cross wedge rolling die has the advantages of being low in production cost, short in design and production time, small in formed number, and capable of being widely applied to manufacturing the shaft parts and improving economic benefits of enterprises.

Description

technical field [0001] The invention relates to a die, in particular to a multi-purpose cross wedge rolling die for producing multiple sizes. Background technique [0002] Cross-wedge rolling is a new technology and new technology for forming shaft parts. It is an emerging technology of the intersection and development of metallurgical rolling and mechanical forging. Its working principle is to use two wedge-shaped dies installed on the rolls rotating in the same direction, under the action of the wedge-shaped protrusions of the wedge-shaped dies, the rolled piece is driven to rotate, and the blank produces continuous local small deformation, and finally rolled into a wedge-shaped pass. Various step shafts. The cross-wedge rolling deformation starts from the contact surface of the rolled piece and the die under the pressure of the die. As the reduction increases, the plastic deformation continues to penetrate inward until the inner part also undergoes plastic deformation. ...
