Manufacturing method of counterweight block easy to weld

Abstract

The invention discloses a manufacturing method of a counterweight block easy to weld. The method comprises the following steps of A1, selecting a metal or alloy material with the melting point approximate to that of a golf club head material, and using the metal or alloy material for casting an outer thin shell of the counterweight block; A2, filling the outer thin shell with a tungsten-based alloy; A3, sintering the outer thin shell and the tungsten-based alloy in a vacuum furnace. According to the manufacturing method, manufacturing methods of welded counterweight blocks in the prior art areimproved; firstly, the metal or alloy material with the melting point approximate to that of the golf club head material is selected to cast the outer thin shell of the counterweight block, and the metal thin shell is filled with the tungsten-based alloy in a spraying mode, so that the firmness and precision of welding are ensured. Besides, compared with the prior art, the manufacturing method avoids repeated use of dies during sintering, decreases the costs of die development and consumption, integrally reduces the production cost and enlarges the application range of the welded counterweight block.

Description

technical field [0001] The invention relates to a golf club, in particular to a method for manufacturing an easy-to-weld counterweight. Background technique [0002] There are 18 holes in golf, and the player who hits the hole with the least number of swings wins. Each hole corresponds to a different venue, and each venue has different environmental obstacles, such as figure 1 As shown, there are bunkers, pools, lakes, woods and rough areas on the way from the teeing area to the green. When hitting, you must hit twice and control the ball in the short grass area. If the distance is too far, it may fall into the bunker , If the distance deviates, it may fall into the forest area, lakes and bunkers. When entering the green, you must control the hitting distance and do not stray into the rough area. In response to different environmental tests, there are usually 14 golf clubs in total, including 3 to 5 woods, 7 to 8 irons, 1 to 2 pitching wedges (PW), and sand traps. One rod ...

Problems solved by technology

[0017] Welded weights are mainly weighted in the traditional way, and the fixed weights are welded to the bottom of the ball head by welding to form a situation where different clubs are weighted separately. However, if the welded weights are selected and the ball head has greater Different materials will cause the color difference between the welding surface and the ball head body. If you choose a material similar to the ball head, it will limit the density adjustment of the weight block. This contradiction greatly limits the effective application of the welded weight block.
