Machining method for spare part of punch pin

Abstract

The invention discloses a machining method for a spare part of a punch pin. The machining method for the spare part of the punch pin comprises the following steps: obtaining the molded surface of a required grinding wheel according to a pattern of the part to be processed; trimming the forming grinding wheel with the target molded surface through a diamond pen; and directly grinding a part block into a target shape by the forming grinding wheel. According to the machining method for the spare part of the punch pin, the forming grinding wheel is adopted for carrying out grinding treatment on the part block, the desired shape is directly obtained, and compared with a point machining mode of slow wire feeding machining and optical curve grinding machining, the linear machining mode is high in efficiency, and simple in machining and good in forming effect especially for an arc surface and a forming surface with multiple radial size changes; and in addition, even if the grinding wheel needs to be trimmed, the whole machining period still has the advantages, and the machining method for the spare part of the punch pin is particularly suitable for machining and production for batch parts.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a processing method for punch spare parts. Background technique [0002] Such as image 3 Shown is a schematic diagram of the shape of a punch. The punch is characterized by many changes in radial dimensions and a smooth transition through the arc surface. Therefore, the traditional machining method by tool turning is difficult to apply and cannot meet the process requirements. At present, for this situation, slow wire processing or optical curve grinding are mainly used. Slow wire processing is limited by the clamping method and cannot be processed at one time. It must be clamped again in the middle, which is inefficient and the molding quality is not as good as the grinding effect. ; while the optical curve grinding process has high molding quality and dimensional accuracy, but the grinding progress is slow. When processing this part, it is necessary to process the upper, low...

Problems solved by technology

[0002] like image 3 Shown is a schematic diagram of the shape of a punch. The punch is characterized by many changes in radial dimensions and a smooth transition through the arc surface. Therefore, the traditional method of machining by tool turning is difficult to apply and cannot meet the process requirements.

At present, for this situation, slow wire processing or optical curve grinding are mainly used. Slow wire processing is limited by the clamping method and cannot be processed at one time. It must be clamped again in the middle, which is inefficient and the molding quality is not as good as the grinding effect. ; while the optical curve grinding process has high molding quality and dimensional accuracy, but the grinding progress is slow. When processing this part, it is necessary to process the upper, lower, left, and right sides one by one. The process requires repeated turning and positioning, and the processing cycle is long.
