<p dir="auto">卸料板是冲压模具中用于卸下抱在凸模上的废料或工件的关键部件。</p>
<h2>二、卸料方式对比</h2>
<h3>2.1 弹性卸料</h3>
<ul>
<li>原理：弹簧或聚氨酯提供卸料力</li>
<li>适用：薄板冲裁（t≤2mm）、精密冲裁</li>
<li>优点：压料效果好、精度高</li>
<li>缺点：卸料力有限</li>
</ul>
<h3>2.2 刚性卸料</h3>
<ul>
<li>原理：固定卸料板强制卸料</li>
<li>适用：厚板冲裁（t≥2mm）</li>
<li>优点：卸料力大、简单</li>
<li>缺点：无压料功能</li>
</ul>
<h2>三、弹性卸料板设计参数</h2>
<h3>3.1 卸料力</h3>
<p dir="auto">F卸 = K卸×F冲<br />
K卸：钢板0.02-0.06，黄铜0.02-0.05，铝0.02-0.04</p>
<h3>3.2 弹簧选择</h3>
<ul>
<li>压缩比：30-45%</li>
<li>预压量：10-15%</li>
<li>至少4个弹簧</li>
</ul>
<h2>四、配合间隙</h2>
