Problems solved by technology

This method of raising the heating temperature for forging does not comply with the process regulations. It is also not allowed to directly use gas heating on the mold for titanium or titanium alloys, because the heating temperature of the gas is much higher than the temperature specified by the process. At this time, titanium or titanium alloys are not allowed. The internal metallographic structure of the titanium alloy is unqualified, so the microstructure of each part of the forged titanium ball head will be completely changed, the mechanical properties will be reduced, and the mechanical properties cannot be guaranteed, which will bring future troubles to the quality of the golf head.

Embodiment 1

[0021] The titanium or titanium alloy golf head component forging method of the present invention, the forging workpiece including the golf head striking surface, upper cover or lower cover of titanium or titanium alloy material, together with the punch and die of the corresponding forging mold Put it in an electric heating furnace (the figure shows a forging piece with the upper cover of a golf head as an example), and place several forging workpieces on both sides of the forging mold in the furnace. After the furnace temperature is heated to the forging temperature (for example, the forging temperature of TC4α+β titanium alloy is 950°C, the forging temperature of TB9β titanium alloy is 730°C, etc.), directly place the forged workpiece on the convex / concave die of the forging mold in the furnace In between, the isothermal forging is carried out to the forged workpiece through the forging die still in the electric furnace with a pressure device. and figure 1 and figure 2 A ...

Embodiment 2

[0029] In this example, an induction coil connected to a power supply is used as an electric heating device for heating the forging workpiece and the forging die. Put the forged workpiece into the forging mold, heat it to the forging temperature with the induction coil together, and then use the pressure equipment to carry out the isothermal forging forming on the forged workpiece through the forging mold. Although this method can also solve the existing problems in the current forging of titanium or titanium alloy golf head parts, it is still inferior to Embodiment 1 in terms of energy consumption and production efficiency.

Abstract

The invention relates to a titanium or titanium alloy golf ball head part forging method. The method includes after heating forging workpieces including a hitting face, an upper cover or a lower cover of a golf ball head made by titanium or titanium alloy to forging temperature, disposing the forging workpieces in a forging die in a same temperature-increasing area and at forging temperature same as that of the forging workpieces for equal-temperature forge-press forming, and then taking the forging workpieces out of the forging die for cooling. Equal-temperature forging and pressing is performed on the forging workpieces of the golf ball head and the forging die while same forging temperature is maintained, currently conventional forging-pressing small-tonnage equipment can be adopted for processing, forged parts can completely meet quality requirements in terms of process, and consumption of titanium or titanium alloy can be greatly saved, so that cost increase is effectively reduced.

Description

technical field [0001] The invention relates to a method for forging titanium or titanium alloy golf head parts. Background technique [0002] One of the characteristics of titanium and titanium alloys is superplasticity at high temperatures, which has been used in the manufacture of complex titanium alloy parts for aerospace. Due to the low density and good strength of titanium and titanium alloys, the volume of wood club heads and iron club heads in golf equipment can be enlarged, so titanium and titanium alloys are widely used to make golf heads. [0003] As the design of golf heads is becoming more and more complicated, the production is becoming more and more difficult. In order to ensure the mechanical properties of titanium alloy parts, the heating temperature during forging must be strictly controlled. The deformation resistance of the striking surface and the upper and lower covers of the complex-shaped golf head is extremely sensitive to the deformation temperatu...
