An automotive OEM put in YANGLI presses line – Blockchain Information Website

Whenever you start to take a look at a program to provide the best-quality automotive elements on the highest yield charges—and throw a brand new materials into the combo—there are a plethora of particulars to think about that may impression the tip deliverable.

Press Issues

If an OEM or tier stamper desires to put in an automatic system to stamp its giant automotive elements, it should first take into account all of the variables equivalent to normal press configuration, press stroke size, die area opening, interference factors, pace, tonnage and power required, and scrap removing.

Tandem or Switch

The OEM or tier stamper should first select the overall press configuration, equivalent to a switch press or press-to-press line.

A switch press requires all of the elements to be nested within the die earlier than biking the press. In a tandem line, the press can cycle as soon as the person element is nested within the die.

In a tandem line, the presses are synchronized by a variable press shift–sometimes 60 levels from one another in order that press 1 will attain backside lifeless middle first, then press 2 will attain backside lifeless middle 60 levels later, and so forth. The press center-to-center distance must be as quick as doable whereas nonetheless permitting press repairs and upkeep. This serves as a baseline for the press placement and all different element placement.

Press Stroke Size, Die House Opening

The press stroke size and die area opening should be large enough to permit the elements to be loaded into the dies with stability. Usually, that requires switch automation with two arms, in addition to a large opening for the left-to-right die area.

If a single-arm switch is used, equivalent to a robotic, the automation will value much less, together with the fee for the left-to-right press opening, as a result of it will likely be smaller, however the trade-off is a much less secure element as a result of it could want time to settle and cease bouncing earlier than being positioned into the die. Full management of the element in the course of the switch from die to die, underneath acceleration, deceleration, and G forces, turns into vital.

Velocity, Tonnage, Power

The required press pace, tonnage, and power should be sufficient to provide on the required price, and the slide movement, equivalent to an ordinary eccentric drive, hyperlink drive, or a servo-mechanical press, must be thought of. All different variable slide motions and numerous interference curves that come into play to accommodate the optimum slide interference/displacement curve have to be thought of as nicely.

Interference Factors

A overview of automation integration right into a press configuration ought to embody taking a look at potential interference factors, equivalent to gib drip trays, oil return traces between the uprights, slide tracked car tracks, management swap brackets, air automation valve connections, and bed-mounted tools equivalent to bolster clamps. If interference is encountered, the OEM or stamper must design across the interference or relocate it to allow the required clearance utilizing a simulation software.

Scrap Elimination

In stamping operations, scrap removing usually is an afterthought. It’s greatest to design forward. Scrap shedding, each by the bolster and mattress, in addition to scrap doorways on the back and front of the press are must-have design options.

Automotive OEM Case Instance

An automotive OEM studied how one can stamp its automotive physique panels, equivalent to hoods, doorways, fenders, physique sides, and lots of the corresponding internal elements. The components have been to be fashioned from each aluminum and metal.

Starting with the overall press configuration for the physique panels, the automaker selected to make use of a tandem line within the perception that this may be incrementally sooner than a switch press.
