Screw tap with self-lubricating cooling structure

Abstract

The invention particularly relates to a screw tap with a self-lubricating cooling structure. The screw tap comprises a screw tap handle, a screw tap head and a cooling lubricating fluid main runner, the cooling lubricating fluid main runner is axially arranged in the screw tap handle and the screw tap head, and further comprises a cooling lubricating liquid auxiliary flow channel, the cooling lubricating liquid auxiliary flow channel is arranged in the screw tap head, a plurality of groups of cooling lubricating liquid are sequentially arranged along the flow direction of the cooling lubricating liquid in the cooling lubricating fluid main flow channel, each group of cooling lubricating fluid sub-flow channels is composed of a plurality of branch cooling and lubricating flow channels whichare uniformly distributed in the circumferential direction, one end of each branch cooling lubricating flow channel is communicated with the cooling lubricating liquid main flow channel, the other end of each branch cooling lubricating flow channel faces the tapping area, the branch cooling and lubricating flow channel is arc-shaped, the screw tap handle, the screw tap head and the cooling lubricating fluid main flow channel, and the cooling and lubricating fluid sub-runners are processed and formed in a 3D printing mode. According to the screw tap, the tapping area can be directly and uniformly cooled, and the cooling cost is low.

Description

technical field [0001] The invention relates to a machining tool, in particular to a screw tap with a self-lubricating cooling structure. Background technique [0002] According to the processing type, the cutting process is mainly divided into: turning, drilling, milling, boring and grinding; [0003] Turning refers to the use of the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank; drilling refers to the process of using the tool to process holes on the workpiece; The blade tool moves on the blank to cut the workpiece into the required shape and size; boring is a cutting process that uses a tool to enlarge a hole or other circular contours; grinding refers to the processing method of removing excess material on the workpiece with abrasives , which belongs to the finishing machining of mechanical processing; [0004] The tap is also a tool used for cutting, but its special type is relatively strong, and i...

Problems solved by technology

[0007] 1. Restricted by the processing technology, the cooling holes are all straight holes. The coolant flowing out of the cooling holes does not directly act on the tapping area, and the cooling effect still needs to be improved.

[0008] 2. It is not easy to have too many cooling holes. Too many cooling holes will lead to insufficient strength of the entire tap, and the vulnerability rate will be greatly increased. Too few cooling holes cannot meet the actual cooling requirements.
