Hydraulic Press Manufacturing

Hydraulic presses are versatile and powerful machines that utilize the static pressure of a hydraulic fluid to deform, shape, and compact various materials. They play a crucial role in a wide range of industries, from metalworking and automotive manufacturing to construction and food processing.

Key Components of Hydraulic Presses:

Hydraulic Power Unit: The hydraulic power unit generates the pressurized fluid that powers the press. It typically consists of a hydraulic pump, a reservoir, and a control system.
Hydraulic Ram: The hydraulic ram is the main component that exerts the force to deform or shape the workpiece. It is connected to a hydraulic cylinder, which is filled with pressurized fluid.
Blank Holder: The blank holder is a device that grips the workpiece during the pressing operation, preventing it from wrinkling or buckling. It can be a simple plate or a more complex system with multiple holding points.
Die: The die is the tool that gives the workpiece its desired shape. It is typically made of hardened steel or other durable materials and is placed on the press bed.
Press Bed: The press bed is the stationary surface on which the workpiece and die are placed. It provides a solid foundation for the pressing operation.

Types of Hydraulic Presses:

Single-Action Hydraulic Presses: Single-action presses have a single hydraulic ram that performs both the forming and trimming operations. They are suitable for simple shapes and materials with good formability.
Double-Action Hydraulic Presses: Double-action presses have two hydraulic rams, one for forming and one for trimming. This allows for more complex shapes and materials with limited formability to be produced.
Triple-Action Hydraulic Presses: Triple-action presses have three hydraulic rams, one for forming, one for trimming, and one for ejecting the finished part. They are used for producing the most complex shapes, such as those with undercut features or re-entrant angles.

Formability of Sheet Metals for the Hydraulic Press Manufacturers

At the end of the nineteenth century, due to the development of sheet-forming technology, sheet metal formability became a research topic. Some of the first researchers interested in this field were us. The formability of sheet metals is affected by many parameters, like material parameters, process parameters, and strain bounding criteria.

Effect of the Radius for the Hydraulic Press Manufacturers

As the blank is struck by the punch at the start of the drawing, it is wrapped around the punch and die radii; the stress and the strain developed in the workpiece are similar to those developed in
bending. The force required to draw the shell at intermediate position has a minimum of three components

The forces required for bending and unbending of the metal flowing from the flange into the side wall.
The forces required for overcoming the frictional resistance of the metal passing under the blank holder and over the die radius.
The forces required for circumferential compression and radial stretching of the metal in the flange.
So increase in the die radius reduces the work required for the deforming as the punch radius has not significant effect on the process but it should be appropriate.
On the profile of the die radii flow of the material takes palace. Most of the bending and unbending takes place in that region. Die radii should be optimized for the minimization of the drawing load.
Some details on the several parameters which affect the optimal die curvature are shown below.

The selection of the punch-to-die clearance depends on the requirements of the drawn part and on the work metal. Because there is a decrease and
then a gradual increase in the thickness of metal as it is drawn over the die radius, clearance per side of 7 to 15% greater than stock thickness helps
prevents burnishing of the side wall and punching out of the cup bottom.

The Clearance between the punch and the die

Clearance between the punch and die for a rectangular shell, at the side
walls, and at the ends is the same as in the circular cup. The radius at the corner may be as much as 50% greater than the stock thickness to avoid ironing in those areas.

Even simplest drawing operation, the thickness of the work metal and die radius offer some restraint to the flow of the metal into the die. For drawing all but simplest of the shape some restraint is required
for controlling the flow of the material. Compressive forces on the metal in the area beyond the edges of the die cause the work metal to buckle.

If this buckled or wrinkled metal is pulled into the die during the drawing operation, it increases the strain in the area of the punch nose to the point at which the work metal would fracture soon after the beginning of the draw. The blank holder force is used to prevent this buckling and subsequent failure. The amount of blank holding force required is one-third of the drawing and the die radius should be large enough to reduce
tearing in the deep drawing process.

Blank holder force increases friction and hence the required punch load. Therefore, blank holder force should be just enough to prevent wrinkling of the flange. The edges of the punch and die are rounded for the easy and smooth flow of metal. Clearance between the die and punch is also provided so that sheet metal could be easily accommodated. Insufficient or large clearance may result in the shearing and tearing of sheet

As we can say that blank holding force prevents blank from the buckling and for the proper distribution of the strain, blank holding force is
required otherwise problems as wrinkles can also occur which is shown in fig: 2.6 with and without friction

Effects of the Press Speed

Hydraulic Deep Drawing Transfer Press Line made by the Hydraulic Press Manufacturers

Speed is of greater significance in drawing stainless steels and heat-resistant alloys than in drawing softer, more ductile metals. Excessive press speed
have caused cracking and wall thinning in drawing these stronger, less ductile materials.

When two metals are in sliding contact under pressure, as with the dies and the work metal in drawing, galling (pressure welding) the tools and
work metal is likely. When extreme galling will occurs, drawing force will increase and becomes unevenly distributed causing a fracture of the workpiece. The selection of the lubricant depends on the ability to prevent galling wrinkling or tearing during the deep drawing. It is also influenced by the ease of application and removal, corrosivity, and other factors.
