At present, multi-direction hot die forging technology can form multi-direction core by pressurizing in many directions, but multi-direction pressure will inevitably lead to complex forging equipment and high price. In order to solve the above problems, the present invention provides a one-way pressurized multi-direction hot die forging die structure. By using a common punch press and pressurizing in one direction, multi-direction holes can be formed, which greatly reduces the cost of multi-direction hot die forging equipment. Its realization principle is to change the former upper and lower die mode into the left and right die mode. The die is not open and close up and down, but open and close left and right. For this reason, the left and right die cores are designed to fix the left and right die cores, whose shape is a cone with small bottom and large top, which is symmetrically split to form the left and right die cores. When the left and right die cores move along their respective guideways at the same time, the left and right die cores open and close. The front and rear sliders are designed to install the side punch in the front and rear directions perpendicular to the left and right directions. Driven by the left and right die cores, the front and rear sliders extend and retract along their respective guideways to complete the core pulling of the side punch. In this way, we only need to design a moving ejector rod, to top the bottom of the left and right die cores, can complete the opening of the left and right die, side punch core pulling and other actions; when the force added to the ejector rod is removed, all parts will fall freely under the action of gravity and complete the reset. We also designed a pull rod for installing the lower punch, which is sleeved in the ejector rod to complete the core pulling of the lower punch.
【技术实现步骤摘要】
一种单向加压的多向热模锻锻模结构
本专利技术属于机械设计制造及其自动化
技术介绍
现在的多向热模锻技术从多个方向加压,能形成多方向孔芯,但多方向加压势必导致模锻设备复杂,价格昂贵。
技术实现思路
为了解决以上问题,本专利技术提供一种单向加压的多向热模锻锻模结构,采用普通冲床,从一个方向加压,就能形成多方向孔芯,大大降低了多向热模锻设备成本。其实现原理是将以往的上下模具方式,改为左右模具方式,模具不是上下张开闭合,而是左右张开闭合。为此,设计用于固定左右模具的左右模芯,其形状是底面小,顶面大的圆锥体,被左右对称剖开,形成左右模芯;左右模芯同时沿各自导轨运动,则左右模芯张开闭合。在垂直于左右方向的前后方向设计用于安装侧冲头的前后滑块,被左右模芯带动,沿各自导轨运动,则前后滑块伸出缩回,完成侧冲头的抽芯。这样我们只要设计一个上下移动的顶杆,去顶左右模芯的底面,就能完成左右模具张开,侧冲头抽芯等动作;当撤掉加在顶杆上的力时,所有部位又在重力的作用下,自由落体,完成复位。我们还设计一个用于安装下冲头的下拉杆,套合在顶杆中,完成下冲头的抽芯。具体,一种单向加压的多向热模 ...
