UNIVERSAL HYDRAULIC DECELERATOR
This device, used primarily for staking or forming operations, helps minimize the bent posts or damage which often occurs with fine parts. It slows the horn descent during the weld time only, thus, allowing proper melting of the post.
For welders without a pre-trigger setting (usually used
for staking), this device activates the force trigger to start the sonics
before part contact, insuring staking consistency. Since deceleration
occurs during the weld time only, the ram is allowed to come down at full
speed until contact and return at full speed after the weld. This decreases
overall cycle time compared to slowing the welder's head speed to allow
Decelerating ram speed just before impact
is great for staking applications.
Ram begins decent at full speed. Ram approaches the 1,200 pound decelerator
Ram engages decelerator and is slowed down before impact with part.
