Baffle plate device of cross-wedge rolling machine

Abstract

The invention discloses a baffle plate device of a cross-wedge rolling machine. The baffle plate device comprises a left bottom plate and a right bottom plate which are fixedly arranged on the left and right sides of a blank. The baffle plate device is characterized in that a left contact plate which is buckled with the step shaft of the blank; the left contact plate is in radial sliding match with the left bottom plate; a left radial position adjusting mechanism is arranged between the left bottom plate and the left contact plate, and is used for enabling the left contact plate to radially move and to be pressed against the outer circumferential surface of the blank; the right bottom plate is provided with a right contact plate; the right contact plate is in radial sliding match with the right bottom plate; and a right radial position adjusting mechanism is arranged between the right bottom plate and the right contact plate, and is used for enabling the right contact plate to radially move and to be pressed against the outer circumferential surface of the blank. The baffle plate device has the advantages that the left contact plate and the right contact plate can move along the radial direction of the blank, and are pressed against the outer circumferential surface of the blank all the time during a rolling process, so that the blank is at a central position; the positioning stability of the blank during the rolling process is ensured; the displacement and shift of the blank are prevented; and the quality and precision of a rolled product are ensured.

Description

technical field [0001] The invention relates to a plastic forming equipment for shaft parts - a cross wedge rolling mill, in particular to a baffle device for a cross wedge rolling mill. Background technique [0002] Cross wedge rolling is a new forming process for shaft parts, which has the advantages of high efficiency and material saving. During the processing of cross wedge rolling, the billet needs to be positioned by the left and right baffles to prevent the billet from shifting during the rolling process. move. At present, most of the baffles in the cross wedge rolling mill are fixed, which can only meet the maximum diameter of the billet in the initial state. Long, when the diameter of the billet is reduced, the fixed baffle cannot play the role of positioning the billet, resulting in the displacement of the billet during the rolling process, which affects the quality and efficiency of the rolled product; in addition, the current fixed The baffle plate can only be ...

Problems solved by technology

At present, most of the baffles in the cross wedge rolling mill are fixed, which can only meet the maximum diameter of the billet in the initial state. Long, when the diameter of the billet is reduced, the fixed baffle cannot play the role of positioning the billet, resulting in the displacement of the billet during the rolling process, which affects the quality and efficiency of the rolled product; in addition, the current fixed The baffle plate can only be used for the processing and production of parts with corresponding shapes. If parts of other shapes are produced, additional baffle plates with corresponding shapes need to be installed, which greatly increases the production cost and is time-consuming and laborious.
