Seal Head Forming Production Line

Introduction

There are many types of heads, which can be divided into oval head, butterfly head, spherical crown head, hemispherical head, bow head, flat bottom head, conical head and so on according to the shape.

The head production line realizes the full automation of feeding, centering, oiling, pressing and discharging of the head in the pressing process, which greatly improves the processing efficiency and quality of the head and reduces the labor intensity of the workers.

Head deep drawing hydraulic press is suitable for cold pressing and bending of metal sheets, deep drawing and other processes. It is a special equipment for producing large heads, drawing cylinders and large metal containers. The head forming part is shown in Figure 1.

The overall structure of the production line

The outline drawing of the head stretching hydraulic press and production line is shown in Figure 2. The body of the head stretching hydraulic press adopts a four-column or frame structure. Generally, the head stretching hydraulic press of the formed parts adopts a four-column type with a simple structure and is guided by the four-column. The head piece with high precision requirements adopts a frame structure and is guided by four-corner and eight-sided plane guide rails, with high guiding precision and strong anti-eccentric load capacity.

Head stretching process

The drawing process of the head drawing hydraulic press is shown in Figure 3. The punch is fixed on the drawing slider, the die ring is installed in the blank holder, the blank holder ring is fixed on the die ring, and the female die is fixed on the moving table On the top, the ejector rotating device is fixed in the lower beam.
