3. 3. YL32 series Four- Column Hydraulic Presses
4. 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. 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.

7. 7. An ilustration of deep drawing
8. 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. 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. 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
