Performance Series Presses

Precision guidance, extended guarding and synchronized density rod adjustments all say "performance". Guidance of the upper motion is achieved through the crosshead design. Precision ground Danly bushing on the upper and lower punch guidance, located very close to the die surface virtually eliminates transverse motion. Hardened and precision ground surfaces provide durability and reliability even in the presence of abrasive powders. The result is minimal tool wear, consistent press motion, and part-to-part repeatability. One lower punch plus shelf-in-the-die, a core rod that takes 50% of pressing tonnage, and two upper punches provides the flexibility of simple-to-complex parts manufacturing. Precise density splits are achieved through the die table float.

Fill, ejection and upper punch positions are worm gear driven and control powder transfer. These can be motorized to save time and setup steps. Modular guarding provides physical barriers for operator safety, spacious enclosures for mounted hardware, easy access and maintenance. Lexan guards at the point-of-operation allow continuous inspection of the compacting process.

Many options are available, including Top Punch Hold Down to protect delicate or thin parts during ejection, dual upper punch system for more complex parts, and upfloat/downfloat core rod with spring or timed release reduce ejection stresses. An automatic greasing system can be added to deliver metered amounts of lubricant at programmed intervals, and computer control of the press can be achieved with Gasbarres Presslog controller. Ask about other options now available.

Multi-Action Series Presses

The Gasbarre Multi-Action Series Mechanical Powder Compacting Press is unique in design utilizing state of the art technology for compacting complex, multilevel structural parts. This exclusive system offers both selective molding and ejection of the die platen and the #1 and #2 punch platens - eliminating the need for expensive bridging of tooling members. This allows greater tonnage to be placed in each punch due to decreased deflection. The #3 punch platen floats with a fixed molded position.

 

Multi-Action Series Features:

  • Three independent lower punch platens plus shelf in the die gives capability for more complex parts
  • Adjustable selective molding stops are on the die platen and the #1 and #2 punch platens.
  • Adjustable selective ejection is on the die platen and the #1 and #2 punch platens.
  • PressLog touch-screen display. Operators know the machine's status at a glance. Password security allows operator, supervisor and maintenance levels of access. Users can check fault logs, store virtually limitless production process information, and access on-line troubleshooting aids. PressLog retains a history of setups. Controls display metric or imperial units and are programmable for your language.
  • Withdrawal ejection system incorporates synchronized dual cams and push rods.
 
 

Sizing/Coining Presses

Gasbarre Products Inc. offers two styles of sizing presses to meet the needs of a wide range of parts. Inclined Automatic Sizing Presses and Upright Automatic Sizing Presses.

 

Inclined Automatic Sizing Press

  • "Die in the Head" design is for maximum speed.
  • Bearings and structural parts requiring little or no orientation are typical parts run on this style of press.
  • Swing-Type Automatic Feeder Arm is adjustable and can be used with a multitude of parts. It comes as standard equipment with the press.
  • Lower Snag Pin System is used with each stroke to position the part.
  • Ejection is accomplished by means of an adjustable knockout barsystem located in the top ram .
 

Upright Automatic Sizing Press with Dial Index Part Feed System

  • Dial Index Unit is standard. This is a ratchet-type rotary feed indexing system, used for many complex parts that require orientation into the die.
  • Index wheel with configured pockets.
  • Index wheel with gripper system for parts with no distinctive O.D. characteristics.
  • Ejection is performed by cam/lift arm system, pushing eachpart out of the die.
  • Automated Parts Feed Systems to the index wheel are available.
  • Dial index unit can be removed for hand sizing.

GASBARRE SERVO ELECTRIC PRESS

The Gasbarre Servo-Electric Press is available for precise compaction of powder into a wide variety of geometries. The technology utilized includes high-efficiency and high-precision servo drives to control the motion of the upper ram, die plate, and automatic die filling systems. Each axis of the press is freely programmable for complete control of the compaction cycle: die filling, upper punch motion/compaction, die motion, and ejection cycle. Movement of the press axes are performed by closed-loop control. This means that extreme precision and repeatability are the result. This high-precision affords for consistent production of compacted powder components
