A cutting device for thread rolling wheel repair

Abstract

The invention discloses a cutting device for thread rolling wheel repairing. The cutting device comprises a tooth alignment unit, a fixing unit and a moving unit. The tooth alignment unit is arrangedon the moving unit and comprises a fixing plate, an adjusting plate, a cutter and a tooth alignment device. The adjusting plate can be fixed to a connecting plate in a sliding manner in the length direction of the connecting plate. The tooth alignment device is arranged on the adjusting plate. The cutter is arranged on the fixing plate in a sliding manner, and the sliding direction of the cutter is perpendicular to the sliding direction of the adjusting plate. The fixing plate is arranged on the moving unit in a sliding manner. The tooth alignment device comprises a tooth alignment piece withthe surface provided with a plurality of first spherical grooves. Balls capable of freely rotating in the first spherical grooves are arranged in the first spherical grooves. When the tooth alignmentpiece is located in a thread rolling wheel tooth groove, the surfaces of the multiple balls make contact with the inner wall of the tooth groove, and the tooth alignment piece is rightly embedded in the tooth groove. By means of the cutting device, the cutting position of the cutter can be rapidly and accurately positioned, and error cutting on the non-damaged tooth groove through the cutter is reduced.

Description

technical field [0001] The invention relates to the field of finishing, in particular to a cutting device for repairing thread rolling wheels. Background technique [0002] The thread rolling wheel is a tool that uses the method of metal plastic deformation to roll out the thread on the thread rolling machine. Due to its working characteristics (relying on its own hardness to roll the thread), the thread rolling wheel needs to have high hardness and certain toughness. [0003] After the thread rolling wheel has been used for a period of time, the teeth of the thread rolling wheel will break. At this time, only a new thread rolling wheel must be replaced. However, due to the high price of thread rolling, and the purchase needs a certain period of time, so for the enterprise Production caused some confusion. Therefore, it is necessary to repair the broken teeth of the thread rolling, so that the thread rolling wheel can be used again. In order to ensure good adhesion betwee...

AI Technical Summary

Problems solved by technology

[0004] The current re-cutting method is to use the original cutting machine for producing thread rolling wheels to cut the thread rolling wheels that need to be repaired again, but in this cutting process, there will be a certain deviation in the positioning of the original tooth grooves At the same time, it takes a lot of time to adjust the positioning. In this way, when cutting the repaired area, when the cutting knife passes through the original alveolar, it will damage the original alveolar part, such as the opening of the alveolar becomes larger, etc.
