Description

用于制作铝合金棒材的模具Mold for making aluminum alloy bars 技术领域Technical field
本发明涉及一种用于制作铝合金棒材的模具，属于机械制造处理技术领域。The invention relates to a mold for manufacturing aluminum alloy bars, belonging to the technical field of mechanical manufacturing processing.
背景技术Background technique
传统的铝合金棒材生产方式是采用正挤压的中心挤压方式，即型孔处于模具的中心并与挤压筒的中心相重合。采用这种方式模具制造简单，挤压变形程度小，挤压力低，不足之处是型材的晶粒度大，容易出现粗晶现象，所获得的力学性能及导电率较低。The traditional aluminum alloy bar production method adopts a central extrusion method of positive extrusion, that is, the shape hole is at the center of the mold and coincides with the center of the extrusion cylinder. In this way, the mold is simple to manufacture, the degree of extrusion deformation is small, and the pressing force is low. The disadvantage is that the grain size of the profile is large, the coarse crystal phenomenon is prone to occur, and the obtained mechanical properties and electrical conductivity are low.
发明内容Summary of the invention

为了解决上述技术问题，本发明提出的技术方案是：一种用于制作铝合金棒材的模具，包括模子、模垫和导流板；所述模垫上设有挤压筒，所述导流板上设有导流孔，所述模子上设有连接挤压筒与导流孔的导流室，所述模子上设有连接挤压筒与导流孔的导流室，所述导流孔的入口位于挤压筒的轴线上，所述导流孔的出口偏离挤压筒的轴线。优选的，所述导流孔的中轴线与挤压筒的轴线的夹角为30-60度。In order to solve the above technical problem, the technical solution proposed by the present invention is: a mold for manufacturing an aluminum alloy bar, comprising a mold, a mold pad and a baffle; the mold pad is provided with a squeeze tube, the diversion The plate is provided with a flow guiding hole, and the mold is provided with a flow guiding chamber connecting the pressing tube and the guiding hole, and the mold is provided with a flow guiding chamber connecting the pressing tube and the guiding hole, the guiding flow The inlet of the orifice is located on the axis of the extrusion barrel, the outlet of which is offset from the axis of the extrusion barrel. Preferably, the central axis of the flow guiding hole and the axis of the extrusion barrel are at an angle of 30-60 degrees.
本发明带来的有益效果是：本发明中通过提高挤压系数来增加变形程度最直接的方式就是选用挤压筒内径较大的挤压机，但这同样将大大增加模具的尺寸与挤压过程的能耗。本发明通过延长导流孔的长度，这相当于增大了挤压筒的内径，间接地增加了挤压系数。因此，采用这种结构，可避免粗晶的产生，同时可充分发挥挤压设备的潜能。The invention has the beneficial effects that the most direct way to increase the degree of deformation by increasing the extrusion coefficient in the present invention is to use an extruder having a larger inner diameter of the extrusion cylinder, but this will also greatly increase the size and extrusion of the mold. The energy consumption of the process. The present invention indirectly increases the extrusion coefficient by lengthening the length of the flow guiding orifice, which corresponds to an increase in the inner diameter of the extrusion cylinder. Therefore, with this structure, the generation of coarse crystals can be avoided, and the potential of the extrusion equipment can be fully utilized.
