D46 Cross Wedge Rolling Machine

 

Cross wedge rolling mill is a new type of forging process equipment. It uses two identical flat wedge-shaped dies that move linearly towards each other, or two identical arc-shaped wedge-shaped dies that rotate in the same direction, to roll the blank in the transverse direction. During the rolling process, the blank is affected by the wedge angle (α angle and β angle), the diameter decreases, and the length increases.

Manufacturing of shaft parts:

The wedge cross rolling process is suitable for the mass production of various shaft parts, such as automobile transmission shafts, crankshafts, camshafts, etc. Such parts usually require high mechanical strength and surface quality, and the wedge cross rolling process can provide better precision and processing efficiency.

Production of fasteners such as bolts and screws:

The wedge cross rolling process is widely used in the production of fasteners with axisymmetric shapes such as bolts and screws, which can improve material utilization and shorten processing time.

Gear blanks:

In gear manufacturing, the wedge cross rolling process can be used to produce gear blanks, especially small and medium-sized gears, which can improve process efficiency and product consistency.

Forging preforming:

The wedge cross rolling process is often used in the preforming process of forgings, making the forgings easier to form in the subsequent forging process, while reducing material waste.

In general, the wedge cross rolling process is suitable for the production of parts with axisymmetric shapes, especially in the case of high-volume production and high-efficiency production requirements, which can significantly improve production efficiency and reduce material waste.

Concise Process

 

The process of Cross Wedge Rolling is concise.It only takes several seconds for the rollers to rotate one circle, and the CWR machine can produce 2 or more pieces at one time if you want (according to the shape of pieces).

Small machining allowance and high material utilization There is no draft angle for CWR machine and the internal and external round angle of CWR machine's billet is small. Benefit from the near net shape forming technology it adopts, the shape of the billet it produces is basically the same as the finished product.

Carbon Steel: This is one of the most commonly used materials, suitable for producing various shafts and forgings.

Alloy Steel: Used for manufacturing parts that require higher strength and wear resistance.

Stainless Steel: Used in applications requiring corrosion resistance, such as chemical equipment parts.

Aluminum and Aluminum Alloys: Suitable for aerospace and automotive components where strict weight control is required.

Copper and Copper Alloys: Used for producing parts in electrical and heat exchange equipment.

Titanium and Titanium Alloys: Used in aerospace and medical device fields due to their high strength and corrosion resistance.

The range of applications for CWR machine is exceptionally vast, as it can process numerous metal materials, including steel, alloy steel, and stainless steel, among others. For each distinct material, it is essential to choose the appropriate die and process parameters.

When dealing with hard materials, such as high-carbon steel and alloy steel, CWR machine can be effectively utilized to roll shaft components of various cross-sectional shapes, including step shafts and hollow shafts.

Moreover, for hard-to-cut materials, such as stainless steel, the cross wedge rolling mill can produce a variety of pipe fittings and profiles through the use of specialized dies and process parameters.

The mold in the wedge cross rolling process is one of the key components, which directly determines the shape, dimensional accuracy and surface quality of the workpiece. The design and manufacture of the wedge cross rolling mold is crucial to the success of the entire process. As the core process equipment, the wedge cross rolling mold determines the final forming quality of the workpiece. High-performance molds must have good wear resistance, heat resistance and high strength, and the mold design needs to be highly precise to ensure processing accuracy and production efficiency. In actual production, the design and manufacture of molds are often customized according to the shape, material and production requirements of the specific workpiece to ensure the best process effect.
