Forming cutter for connecting hole between golf club head and golf club handle

Abstract

The invention discloses a forming cutter for a connecting hole between a golf club head and a golf club handle. The forming cutter is sequentially provided with a first reaming section, a first transition section, a second reaming section, a second transition section and a third reaming section, wherein the first reaming section comprises an end face knife arranged on the end face of a knife headand a first reaming blade part extending towards the side face of the knife head, and a chamfering blade part is arranged at the shoulder position of the first reaming blade part; the first transitionsection is provided with a reinforcing inclined blade part of which the inclination angle is the same as the inclination angle of the chamfering blade part; the second reaming section is provided with a plurality of second reaming blade parts; the second transition section is provided with a reinforcing taper blade part of which the inclination angle is the same as the inclination angle of the chamfering blade part; and the third reaming section is provided with a plurality of third reaming blade parts. According to the forming cutter, the multi-step connecting hole can be efficiently and accurately drilled in the reaming process, and the chamfering blade part, the reinforcing inclined blade part and the reinforcing taper blade part are arranged, so that the blades are not prone to abrasion when the diameter of the hole during drilling process is expanded; and in addition, only two blades of the end face knife pass through the center, so that the alignment is accurate, and the chip removal amount is increased.

Description

technical field [0001] The invention relates to a processing cutter, in particular to a forming cutter for a handle hole of a golf head. Background technique [0002] Golf clubs are basic equipment in golf, including a ball head and a handle. In order to ensure the strength of hitting the golf ball, the ball head is usually made of metal, while the handle is made of other tough materials. Usually, the two are processed separately and then assembled and connected. Therefore, whether the processing accuracy of the connecting hole of the golf head can be guaranteed is the key to the quality of the finished product. During production, it is usually necessary to process a multi-level connection hole in the metal golf head, and then tap the teeth in the connection hole. Since the ball head is usually made of stainless steel with high hardness, a small hole will be left during casting, which is convenient for the tool to expand the small hole into a connecting hole. However, the...

Problems solved by technology

However, the tools used in reaming often ignore the strength of the cutting edge in order to improve the accuracy, resulting in severe wear and even fracture of the cutting edge.
