Introduction to the production line of metal head forming spinning machine

Manufacturers of metal industrial heads for tanks and pressure vessels need a hydraulic press for the bottom of the head, and a CNC head hydraulic spin forming machine.

ALTRON provides high performance and efficient yet stable machines. The production line combines a cutting-edge disc head press with automatic manipulators, spinning and flanging machines to achieve the reliability of head size production and meet the quality and stability of disc head manufacturers for welding and splicing.

Metal head manufacturing starts with laser cutting of sheet metal and cutting of circular blanks. The processing capacity of the standard head production line is within 10 mm of stainless steel plates; the disc press is used with a special pressing mold to process the convex arc position of the metal head through multiple repeated impacts. This action is systematically performed in an automatic cycle managed by the CNC system, which also guides the manipulator to evenly distribute the impact force on the bottom of the dished head, allowing it to gradually eliminate internal stress and form to the desired shape.

After the bottom contour of the metal head is formed, the metal head spinning machine begins to spin the outer contour of the butterfly head. The bottom of the head is fixed by the upper and lower hydraulic cylinders. The large-diameter hydraulic forming wheel and the head spinner The pressure wheel spins once according to the set trajectory. Most heads are cold formed. In special materials, an annealing process is used to eliminate the internal stress of the material, making the production of industrial heads more consistent; in large quantities During the production process, CNC control is used to ensure the consistency of the outer diameter data of the head; to ensure that the dished end meets precise specifications, the ALTRON head spinning machine can be added with a chamfering tool for girth seam welding. Strength and welding water permeability have better results.

Metal Head Bottom Hydraulic Press Machines

ALTRON has launched a series of head drum presses with a unique rod design.

The upper and lower hydraulic cylinder pressure is equipped with a proprietary system, which effectively reduces damage to the machine frame during the head pressing process and ensures the reliability of the precision pressing process. In order to efficiently produce metal heads, ALTRON provides automatic manipulators to automatically load and unload raw materials and semi-finished products of the heads, and configure them according to actual needs.

The disc end forming machine is an industrial special equipment designed for head forming applications. It has reliable positioning and good operability, effectively reducing the high-intensity work tasks of production labor workers, while optimizing the overall workflow efficiency.

Metal Head External Spinning Flanging Forming Machine

After the bottom of the metal head is processed, the outer edge needs to be flanged and spin-formed. There are many processes that can be completed here.

The following equipment introduces how to use the flanging process to process the outer contour of the metal head. During the flanging operation, the upper and lower hydraulic spindles fix the blank, and the CNC servo system moves it to the specified diameter range to determine the center position of the head. The eccentric mold of the forming contour inside the head is close to the inside of the head, so that The head has sufficient strength support during the forming process; the upper pressure plate presses it against the outer contour of the head, allowing it to have greater contact force with the inner contour forming mold to avoid slipping and idling during the head forming process. In this case, the upper flanging wheel spins downward and spins according to the contour of the inner forming mold. The metal sheet realizes plastic deformation in the two rotating wheels under the strong hydraulic driving force.

A head with a larger diameter will have greater internal stress, commonly known as metal rebound. There will be a certain deviation between the theoretical head diameter and the actual formed head. We can solve the outer diameter tolerance through compensation in the CNC system.

Precautions:

As the radius of the metal head is adjusted, the forming wheel rotates in conjunction with the inner contour mold and manipulates the material to achieve the desired curvature, a long operation that causes delamination of the sheet metal. It ensures the best forming effect, minimizes material thinning, and achieves flanging and spinning forming in a few times.

Altron’s high-quality metal head flanging machines have absolute advantages in this industry.
