Wear measuring device and measuring method for the boundary edge of the wedging section of the cross-wedge rolling die

Abstract

The invention discloses a wear measuring device and measuring method for a wedging section border edge of a cross wedge rolling die. The wear measuring device is characterized in that a support and two parallel guide rails are included, the two guide rails are fixedly connected with the two sides of the border edge respectively and are attached to the arc-shaped bottom face of the die, the guide rails are provided with multiple steps which gradually rise in the direction of a wedge, each step is provided with a groove, the support is horizontally arranged in the groove of one step and is vertically fixed to the guide rails, the support is fixedly connected with three dial indicators in the length direction, the dial indicator in the middle is located on the upper portion of the wedging section border edge of the cross wedge rolling die, and the other two dial indicators are located at the two ends of the support respectively and located on the upper portion of the arc-shaped bottom face of the cross wedge rolling die. The wear measuring device and measuring method have the advantages that wear of an actually used cross wedge rolling die can be measured, especially the wear extent of the wedging section border edge of the die, effective data information is provided for wear researching of the cross wedge rolling die, the measuring device is simple in structure, and measurement results are relatively accurate.

Description

technical field [0001] The invention relates to a cross-wedge rolling die, in particular to a wear measuring device and a measuring method for the boundary edge of the wedging section of the cross-wedge rolling die. Background technique [0002] The cross-wedge rolling die is in a complex and harsh working condition of high temperature and high pressure during the rolling process, and the die wear is relatively serious, especially the position where the two wedge surfaces intersect on the die-the edge of the wedge segment, due to the burden Most of the workpieces are wedged into the task and therefore wear the most. However, due to the fact that the cross wedge rolling die used in the actual cross wedge rolling process has a radian, a large volume, and a complex geometry, ordinary wear measurement methods such as weighing method, depth loss method, and contour method are used to measure its wear. Implementation is difficult, imprecise, and costly. Therefore, it is very dif...

Problems solved by technology

However, due to the fact that the cross wedge rolling die used in the actual cross wedge rolling process has a radian, a large volume, and a complex geometry, ordinary wear measurement methods such as weighing method, depth loss method, and contour method are used to measure its wear. Difficult to implement, imprecise, and costly

Therefore, it is very difficult to measure the wear of the cross wedge rolling die in actual use at present, which is limited by many factors, especially the wear measurement of the boundary edge of the wedging section on the die
