Head stretching hydraulic press_800 tons three-beam four-column hydraulic press

The 800-ton head stretching hydraulic press is an 800-ton three-beam four-column hydraulic press designed by Shandong Woda Heavy Machinery CO.,LTD. according to customer production needs. The machine adopts a three-beam four-column structure with a pressure cylinder, which is a typical head stretching machine. The equipment can be used to press heads of various specifications and end caps of pressure volume. The heads pressed by this machine are cold-pressed and formed in one step without heating. The head stretching hydraulic press designed and manufactured by Shandong Woda Heavy Machinery CO.,LTD. is reasonably designed. Welcome to visit and inspect on site.

800 ton three-beam four-column hydraulic press

The 800-ton head stretching hydraulic press has a simple structure and is easy to use. The key is that the initial investment cost of the machine is low, and it is an affordable equipment for the majority of head manufacturers. It is suitable for cold and hot forming pressing of various pressure vessel heads. The 800-ton three-beam four-column hydraulic press consists of a machine body, a main cylinder, a side pressure cylinder, a stroke limit device, a lubrication device, a hydraulic power system, and an electrical system. The tonnage of the stretching hydraulic press used is different according to the diameter of the head. 100-ton to 5000-ton stretching hydraulic presses can be customized.

Features of 800-ton head stretching hydraulic press:

1. Four-column structure, high overall strength, easy to disassemble the mold;

2. The tensile force and the blank holding force can be set separately, and the forming process is controllable;

3. The working pressure and working speed can be freely adjusted according to the customer's process, suitable for batch production of heads of various specifications;

4. The hydraulic control adopts a cartridge valve integrated system, which reduces leakage points, ensures reliable and stable operation and long service life;

5. The head hydraulic press adopts PLC control system, with compact structure, sensitive and reliable operation and good flexibility;

6. The head hydraulic press adopts advanced hydraulic transmission system, stable performance, adjustable pressure, and can produce heads of different shapes and specifications by changing molds. It is a widely used four-column hydraulic press.

7. The main feature of the head stretching hydraulic press is that the main cylinder (i.e. the stretching cylinder) is connected to the upper beam and passes through the reserved through hole in the middle of the sliding beam, and is not connected to the sliding beam, and acts on the material plate to form a tensile force; and the sliding beam, under the push of the edge pressing cylinder, forms a edge pressing force on the material plate through the edge pressing die. The number of edge pressing cylinders is generally 4, 6, 8, 12, etc., and is connected to the sliding beam through a flange.

Parameters of head stretching hydraulic press:

Compared with the traditional processing mode, the head stretching hydraulic press is faster and can produce a finished product in 3-4 minutes, with low labor costs, and does not require great technical skills from workers. It only requires simple operations to press out the product. The product is pressed out in a cold press, and the shape is full; the head hydraulic press has an independent power mechanism and electrical system, which is suitable for the pressing process of plastic materials, such as stamping bending, flanging, thin plate stretching, etc. In addition, it can also be used for correction, press fitting, powder product molding and non-metallic material pressing.

800-ton three-beam four-column hydraulic press stretching head action sequence:

The process action sequence is: the main oil cylinder descends and contacts the material plate without pressurizing → the edge pressing cylinder moves downward, driving the sliding beam and the edge pressing mold to press the material plate and maintain pressure → the main cylinder presses for stretching → the main cylinder releases pressure → the edge pressing cylinder releases pressure and returns → the main oil cylinder returns → the ejector cylinder ejects the mold → the ejector cylinder returns to its original position.
