Quick Die Change System in Press Machining
Pascal Engineering offers state-of-the-art pneumatic- or hydraulic-powered press machine parts for automating production. The Pascal Quick Die Change System (QDC) utilizes automated die clamps to increase productivity by removing the setbacks associated with the traditional die change method.
Die clamping is simplified by integrating hydraulic or pneumatic die clamps, and die transfer is made significantly easier by setting them on Pascal pre-rollers. Time savings and safety are ensured, which increases satisfaction on the part of operators, production managers and customers alike.
Benefits of Using Automated Die Clamps
Someone forgot to place or remove a bolt, and now he or she must climb into the press to tighten it. Sound familiar? Not only is it extremely dangerous to do work while inside the press, workers can easily lose their footing while climbing in as well.
Instead of manually tightening and loosening each bolt, Pascal’s hydraulic or pneumatic clamps slide easily into the T-slots to clamp the die with the push of a button. A die detection sensor and die storage sensor option are also available, allowing you to verify where the clamps are at all times.
Pascal travel clamps automatically travel to and from the die. This eliminates the need for operators to touch the clamps altogether — significantly reducing the safety risks associated with die changeover.
Failure to tighten all the bolts in a die allows the die to “breathe” during production, and this reduces part quality and consistency. It is also common for the die or other equipment to sustain damage by fork trucks moving in and out of the press during die change.
Pascal’s system eliminates these issues. Our clamps reliably clamp your tooling with the same force every time. With Pascal die lifters and pre-rollers, you can use an overhead crane to place the die on the pre-rollers and push the die by hand. If a fork truck is needed, the pre-rollers stop it from getting too close, preventing damage and bodily injury.
Placing the die in position, and loosening and tightening bolts to secure the die to the press can take a lot of time. Time wasted on die change can affect delivery. The time spent on a die change is time taken away from production — and this can result in missing a delivery schedule.
Pascal clamps clamp and unclamp in a few seconds. Over time, use of Pascal’s Quick Die Change (QDC) solutions can potentially save hours that would otherwise be spent on die change. The time and money saved can be used to increase production, provide more training, and optimize the utilization of operators and machines.
Gas Springs in the Stamping Business
In the stamping business, downtime resulting from frequent coil spring failure can be costly. Gas springs are a good alternative for reducing downtime and improving product quality. A die with coil springs can be retrofitted with Pascal gas springs with simple modifications to meet your needs. We stock gas springs in our warehouse to provide same-day shipping.
Gas Springs in Press Machining
Gas springs have become popular in stamping die applications in recent years because gas springs have many advantages over conventional coil springs. Advantages of the gas spring include higher initial contact force, availability in compact profile (smaller shut height) and durability. Since they are compact and capable of producing high forces, fewer springs are required to achieve the desired force, which means that the die can be built with less machining and less material, resulting in reduced weight.
Gas Spring Application in Automotive
Pascal gas springs are available in many strokes and sizes to meet the required force within the die. Typical applications are lifting stock, drawing (to hold the bead), blanking (to strip the punch) and piercing (stripper plate, stripper unit and cam units).
The increased use of High Tensile Strength Steel (HTSS) in recent years has resulted in a growing need for the gas springs. HTSS is very strong yet lightweight, and the reduced weight improves the vehicle’s fuel efficiency without compromising safety. Also, because HTSS is brittle and difficult to form compared to conventional steel, more initial force is required than coil springs can achieve.
