The document discusses hydraulic presses made by Anhui Lai Fu NC Machine Tool Co. Ltd. Specifically, it describes their YL32 series four-column hydraulic presses. The presses have a three-beam, four-pole structure for stability and space for large dies. They can be operated manually or semi-automatically. The presses offer accuracy, rigidity, stability, flexible controls, safety features, and the ability to precisely control stroke and pressure. Deep drawing is also discussed, which uses hydraulic presses or double-action presses to form sheet metal parts through drawing and stamping.

4. Detailed information of the YL32
series Four- Column Hydraulic
Pressess
 The Hydraulic press has three-beam and four-pole
structure, which means economical and practical.
Operation space is wide, and the movable bolster
could be moved out of frame to set the die. The
structure is simple and the appliance is also
beautiful. Hydraulic control adopts plug-in valve
system, which means reliable motion and long
service life. The press,, which could realize three-
operation mode: adjustment, manual and semi-
automatic. The machine is applicable for metal
sheet stretching and pulling, stretching, punching,
bending. It is also used for pulling, stretching and
pressing large-scale products.

5.  Presses offer fast, easy, and safe setup and operation as well as years of
trouble-free service.
1. 4-post frame provides maximum rigidity and minimum deflection for
accurate parts and long tool life. Thick plates and large columns provide
you with the stable platform you need for your demanding application
2. Long bearing length offer improved stability and resistance to off-center
loading
3. PLC press control is flexible and safe. PLC controls allow for customized
press
4. Dual Palm Button control: anti-tie down, non-repeat controls with ring
guards; conforms to OSHA.
5. Adjustable proximity switches allows stroke adjustments in seconds
6. Pressure control and gauge allow tonnage adjustment in seconds.
7. Selector switch modes of operation: jog (setup) and run (cycle）
8. Wide range of hydraulic systems to match your requirements
9. Large reservoirs minimize the need for oil cooler
10. Large daylight accommodates large dies. Special daylights and bed sizes
are available
11. Long stroke lengths are adjustable from about 2 m to maximum. Special
stroke lengths are available.
12. Pressure and distance reversal systems are standard.

8. Deep drawing presess
 Sheet metal material is mostly used “body part material” in automotive
and household appliances industry. Sheet metal forming presses are in
this meaning very important structure of production process of
automotive and household appliances industries, as also in electronic
and other industries.
Deep drawing presses can be mechanical, hydraulic or combined. The
technique of deep drawing can be used on all kinds of presses -
transfer, progressive, tandem lines and single die. But usually when we
speak about deep drawing presses, we are talking about double
action (DA) sheet metal forming presses. There are two technologies /
versions of deep drawing of sheet metal parts. One is deep drawing
with double action presses (DA), which have two slides – inner and
outer.
The double action presses can be mechanical, hydraulic or
combined(with one slide hydraulic and other mechanic). Another is
deep drawing with mechanical or hydraulic press, where the blank
holder is a part of die (tool) mounted on the slide of the press.

9.  At deep drawing it is necessary to hold the sheet
metal blank that is being drawn (formed) with the
blank holder.
1. At mechanical or combined double action (DA)
presses the function of “blank holding” is
performed with the outer slide of the press, while
the punch die mounted on inner slide (also
sometimes called as punch) performs the “deep
drawing” while punching through the blank and
pushing it into matrix of the lower die.
2. Another technique of the deep drawing is
performed on mechanical or hydraulic
presses with hydraulic die cushion in the table of
the press. On these presses the punch die
mounted on the slide should also include the
blank holder as part of the upper die.

10. Advantages of Hydraulic Presses
 Full power stroke
 Built- in overload protection
 Much lower original cost and operating costs.
 Larger capacities at lower cost.
 More control flexibility.
 Greater versatility
 More compact
 Lower tool cost
 Safety
