The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, mounting and adjusting is convenient, it is suitable for the high velocity ram machine punching press bottom dead centre holdup time adjusting apparatus that high-speed punch press punching head guide posts are connected with slider of punch, the spring that the structure is equipped with by carrier, extend time when slider of punch motion bottom dead centre is detained, workpiece is set to reach the maximally effective time limit in the deformation produced by upper punch pressure, after workpiece punching press is completed, make shaping completely in place, product quality is improved, the above mentioned problem that existing high velocity ram machine has stamping defect is compensate for.
The technical scheme that the utility model is used is, a kind of high velocity ram machine punching press bottom dead centre holdup time adjusting apparatus, including the drift guide posts being connected with high velocity ram machine bent axle, connecting rod, and the sliding block being connected with drift guide posts, the junction of the drift guide posts spindle nose and sliding block is provided with recessed carrier, carrier is equipped with spring, and the spindle nose of drift guide posts passes through spring, linked into an integrated entity by the trip bolt and sliding block of slider bottom.
High velocity ram machine punching press bottom dead centre holdup time adjusting apparatus described in the utility model, is further characterized in that,
The spring that the carrier is equipped with is multiple butterfly springs.
The sliding block carrier installs the axis hole of drift guide posts spindle nose built with copper sheathing.
The utility model high velocity ram machine punching press bottom dead centre holdup time adjusting apparatus, spring is additionally arranged in high-speed punch press punching head guide posts spindle nose and the recessed carrier in sliding block junction, sliding block is set to be detained certain time in punching press bottom dead centre, extend the period of punching press bottom dead centre, the deformation allowed produced by the stamping press that workpiece is subject to has reached the maximally effective time limit, the position of some more difficult shapings of workpiece is set to be fully formed in place, the quality of stamping products is improved, the stamping defect that existing high velocity ram machine is present is compensate for.
