Description

Technical Field

[0001] The present application relates to the technical field of cooling water nozzle processing equipment, and in particular to a crimping tool for a cooling water nozzle. Background Art

[0002] The cooling nozzle is an important part used for cooling processing equipment. Its main function is to cool the workpiece through water flow to ensure the processing quality and the normal operation of the equipment. When crimping the cooling nozzle, a crimping tool is needed to assist the cooling nozzle in crimping assembly. After searching, the patent document with the authorization announcement number CN214519922U announced a crimping tool for a cooling water nozzle, including a clamping component and a pressing seat, wherein the middle outer wall of the cooling water nozzle is provided with a flange, and the front outer wall is provided with a boss; the clamping component is arranged on the outer wall of the cooling water nozzle between the flange and the boss; the clamping component also includes a convex edge arranged at its rear end; the pressing seat is sleeved on the outside of the clamping component, and the convex edge is located between the flange and the end face of the pressing seat close to the flange. The crimping tool for the cooling water nozzle crimps the convex edge through the pressing seat, so that the front end of the clamping component generates a driving force and a supporting force opposite to the driving force on the flange through the crimping surface, and the supporting force is transmitted to the boss through the convex edge, so that the force point of the cooling water nozzle is moved forward to the boss, thereby avoiding damage to the upper end face of the water nozzle caused by crimping. While ensuring the quality of the upper end face of the water nozzle, the coaxiality of the press-fit is better guaranteed to avoid the skew of the cooling water nozzle.

[0003] In actual operation, it was found that the above-mentioned related schemes still have at least the following shortcomings: in the process of applying force to the cooling water nozzle to press the cooling water nozzle and the clamping component into the press seat, there is no function to limit the depth of the cooling water nozzle and the clamping component pressed into the press seat. Once the cooling water nozzle and the clamping component are pressed into the press seat to a greater depth, the convex edge of the clamping component may be easily squeezed and damaged by excessive extrusion pressure, thereby affecting the crimping quality. Therefore, we propose a crimping tool for a cooling water nozzle to solve the above-mentioned problem. Utility Model Content
