The main forms and basic structural components of the rolling tools in titanium material processing

I. Main Forms of Rolling Tools in Titanium Material Processing
Rolling tools can be classified based on the angle between the main shaft and the horizontal direction: when the angle is zero, it is a straight rolling tool; when there is an inclination angle, it is an inclined rolling tool.

A certain number of spokes are placed in a plastic cylinder with many small holes to form a unit. During the operation of the straight rolling tool, this structure can effectively prevent the spokes from falling out. However, due to the need for the plastic cylinder to be sealed, it is inconvenient to load and unload, and the auxiliary working time is relatively long. Therefore, it is only suitable for small-batch production.

Depending on the load capacity, the inclination angle of the inclined rolling tool is generally 30 degrees or 45 degrees, and there are two types: single-sided and double-sided. In the inclined rolling tool, the flower holes on the flower plate correspond to each cathode conductive unit. During operation, a certain number of spokes are placed in the flower holes and the retaining rings outside the cathode conductive units. The operator can easily load and unload the spokes with both hands, reducing the auxiliary working time, and it is suitable for large-batch production.

The rotational speed of various types of rolling tools is generally designed to be within 10 r/min, with a typical speed of 46 r/min.

II. Basic Structural Components of Rolling Tools in Titanium Material Processing
1. Support: The local support is the main support part of the rolling tool. It should be stable during lifting and have good insulation for the part immersed in the electrolyte. It can be coated with fiberglass reinforced plastic.

2. Transmission: It enables the main shaft to reach the specified rotational speed. It should be noted that the manufacturing accuracy of the polyvinyl chloride gear working in the electrolyte should be negative tolerance, and a gear mechanism should be used for speed reduction. There should be a certain amount of slack during operation to fully consider the impact of thermal expansion and contraction on gear meshing (the linear expansion coefficient of polyvinyl chloride is 56 times that of steel). Otherwise, in high-temperature electrolytes (such as copper-tin alloy or nickel, with a working temperature of 55-60°C), it may cause poor operation or even jamming.
