Description

Technical Field

[0001] The utility model belongs to the technical field of knurling forming, and particularly relates to a double-wheel knurling tool with adjustable spacing. Background Art

[0002] Knurling is a common anti-slip process in metal surface processing. At present, there are two processing methods and tools for knurling in the market. The first is to use a single-wheel knurling wheel with a knurled pattern for rigid knurling, and the second is to use a double-wheel opposite helical knurling wheel for rigid knurling. After retrieval, the patent application number "CN202321599056.4" discloses "a double-wheel knurling tool with adjustable spacing", which records that "the first tool handle can switch positions between the second installation position and the second installation position, and the second tool handle can switch positions between the third installation position and the second installation position, realizing the position and spacing adjustment of the first roller and the second roller, so that the knurling tool can match the knurling processing of workpieces of various sizes. After the position adjustment, the first tool handle and the second tool handle are fixed by a reinforcement component". By using the fact that the first tool handle can switch positions between the second installation position and the second installation position, and the second tool handle can switch positions between the third installation position and the second installation position, the position and spacing adjustment of the first roller and the second roller is realized, and indeed the knurling tool can match the knurling processing of workpieces of various sizes. After the position adjustment, the first tool handle and the second tool handle are fixed by a reinforcement component. However, the above comparative document still has the following problems in actual use:

[0003] In actual use, the increase or decrease of the spacing achieved by angle adjustment easily leads to inaccurate accuracy during use, and the tool handle and its rollers cannot be replaced during use, resulting in troublesome replacement after long-term use.

[0004] Based on this, providing a tool that can achieve more accurate spacing and angle adjustment and can replace the tool handle and its rollers has extremely high practicality. Summary of the Utility Model
