一种管内定位的缩径模具的工作方法
摘要：
本发明揭示了一种管内定位的缩径模具的工作方法，包括：加压模具，所述加压模具设有容置管材的腔体，其特征在于，所述加压模具的一端固定设有第一定位芯子，所述第一定位芯子包括第一芯子和第一卡接部，所述第一芯子位于所述加压模具的轴线上，在所述加压模具的另一侧设有第二定位芯子，在静止状态下的第二定位芯子的第二芯子与所述加压模具的轴线有夹角，在工作状态下的所述第二芯子位于所述加压模具的轴线上，本发明的技术方案能够将管材进行定位同时可以对管材进行支撑作用，提高管材的加工性能。
摘要（英）：

The invention discloses an in-pipe locating hole-shrinkage die which comprises a pressurization die. The pressurization die is provided with a cavity for accommodating pipes. The in-pipe locating hole-shrinkage die is characterized in that a first locating core is fixedly arranged at one end of the pressurization die and comprises a first core and a first clamping part, the first core is located on the axis of the pressurization die, a second locating core is positioned on the other side of the pressurization die, and a second core of the second locating core in a static state and the axis of the pressurization die form an included angle, and the second core in a working state is located on the axis of the pressurization die. According to the technical scheme, the pipes can be supported while being located, and the pipe processing performance is improved.
