技术领域technical field
本发明涉及钛合金反重力铸造领域，具体地说，涉及一种钛合金构件真空低压铸造成形装置，属于铸造及铸造设备领域。The invention relates to the field of titanium alloy anti-gravity casting, in particular to a vacuum low-pressure casting forming device for titanium alloy components, which belongs to the field of casting and casting equipment.
背景技术Background technique
钛合金具有密度低、比强度高、耐腐蚀等优异的综合性能，是航空航天领域内一种重要的结构材料。离心铸造是钛合金铸造最常用的方法，但是铸造过程中工艺参数不易控制，并且离心力的存在会造成铸件化学成分的不均匀性，最终导致铸件力学性能的不均匀性。在中国专利[201010615723.4：一种小型钛合金或钛铝合金复杂铸件的铸造成形方法]中，该发明提出一种底漏式真空吸铸熔模精密铸造方法成形钛合金铸件的方法，该方法借助重力及真空吸力使合金液沿重力方向充型，属于重力铸造范畴，充型过程中无法对合金液流速及流态进行控制，影响铸件最终的内在质量。在中国专利[200810150364.2：一种钛及钛合金的铸造方法]中，该发明采用了一种类似于真空吸铸的方法，通过快速抽取上炉腔真空，使纯钛或钛合金液沿升液管逆重力方向进入铸型壳中。但真空吸铸的吸铸力有限，合金液的充型动力及凝固补缩压力都较小，无法用于较大铸件的生产。Titanium alloy has excellent comprehensive properties such as low density, high specific strength and corrosion resistance, and is an important structural material in the field of aerospace. Centrifugal casting is the most commonly used method for titanium alloy casting, but the process parameters are not easy to control during the casting process, and the existence of centrifugal force will cause the inhomogeneity of the chemical composition of the casting, which will eventually lead to the inhomogeneity of the mechanical properties of the casting. In the Chinese patent [201010615723.4: A Casting and Forming Method for Small Titanium Alloy or Titanium Aluminum Alloy Complex Castings], the invention proposes a method for forming titanium alloy castings by a bottom-drain vacuum suction casting investment casting method. Gravity and vacuum suction make the alloy liquid fill the mold along the direction of gravity, which belongs to the category of gravity casting. During the filling process, the flow rate and flow state of the alloy liquid cannot be controlled, which affects the final internal quality of the casting. In the Chinese patent [200810150364.2: A Casting Method of Titanium and Titanium Alloy], the invention adopts a method similar to vacuum suction casting, by quickly extracting the vacuum in the upper furnace chamber, the pure titanium or titanium alloy liquid rises along the liquid The tube enters the mold shell against the direction of gravity. However, vacuum suction casting has limited suction casting force, and the filling power and solidification and feeding pressure of alloy liquid are relatively small, so it cannot be used for the production of larger castings.

工作流程：work process:
钛合金熔炼开始前，先将锁紧密封机构8打开，移走上室9和中隔板6，向水冷铜坩埚4中加入钛合金料。将中隔板6放置到锁紧密封机构8后，在中隔板5上放置升液管5，使升液管5处在水冷铜坩埚4上方，并在升液管法兰上下面放置耐火材料的密封垫7。将铸型摸壳15的浇口与升液管口位置对齐，放置于中隔板6上，利用模壳锁紧机构14将模壳固定，实现模壳和升液管与上下腔隔板之间的密封。将上室9放置到锁紧密封机构8中，并锁紧密封，使上下室之间密封隔离。通过电极接口11对电阻丝10通电，实现对铸型模壳的预热保温。Before the titanium alloy smelting starts, the locking and sealing mechanism 8 is opened, the upper chamber 9 and the middle partition 6 are removed, and titanium alloy material is added into the water-cooled copper crucible 4 . After placing the middle partition 6 on the locking and sealing mechanism 8, place the liquid riser 5 on the middle partition 5 so that the liquid riser 5 is above the water-cooled copper crucible 4, and place a refractory pipe above and below the flange of the riser. Material of gasket7. Align the gate of the mold shell 15 with the position of the riser nozzle, place it on the middle partition 6, and use the mold case locking mechanism 14 to fix the mold case, so as to realize the connection between the mold case and the riser pipe and the upper and lower chamber partitions. between the seals.

Since the liquid riser 5 is above the water-cooled copper crucible 4, it is preheated by induction melting radiant heat, which can reduce the chilling effect of the liquid riser 15 on the titanium alloy melt during the low-pressure casting process.
熔炼结束后，开始真空低压铸造。首先根据工艺需求在计算机控制软件中输入相应低压铸造工艺参数，参数输入完毕后，工控机将参数下传至PLC中的存储器中。然后关闭上室进排气电磁阀16和上下室互通电控截止阀18，水冷铜坩埚4在升降机构29的带动下快速上升，使升液管5浸入钛合金熔体之中。打开气源电控截止阀、下室进排气电控截止阀，在计算机控制系统调控下，按照参数设置实时调节数字组合阀22的进气流量，使保护气体以一定的速度充入下室1中，这样，在上、下室之间形成压差，钛合金熔液在压差作用下沿升液管上升并进入铸型型腔中，在一定压差作用下凝固成形，实现钛合金真空低压铸造过程。After smelting, start vacuum low-pressure casting. First, input the corresponding low-pressure casting process parameters in the computer control software according to the process requirements. After the parameters are input, the industrial computer will download the parameters to the memory in the PLC. Then close the upper chamber intake and exhaust solenoid valve 16 and the upper and lower chamber intercommunication electric control shut-off valve 18, and the water-cooled copper crucible 4 rises rapidly under the drive of the lifting mechanism 29, so that the liquid riser 5 is immersed in the titanium alloy melt. Open the air source electric control cut-off valve and the lower chamber intake and exhaust electric control cut-off valve, and under the control of the computer control system, adjust the intake flow of the digital combination valve 22 in real time according to the parameter settings, so that the protective gas can be filled into the lower chamber at a certain speed In 1, in this way, a pressure difference is formed between the upper and lower chambers, and the titanium alloy melt rises along the riser pipe under the action of the pressure difference and enters the mold cavity, and solidifies and forms under a certain pressure difference to realize the titanium alloy Vacuum low pressure casting process.
在钛合金铸件凝固后，关闭气源电控截止阀21，打开上下室互通电控截止阀18，卸除上下室之间的压差，是升液管内未凝固合金液流回坩埚内，启动坩埚升降机构29，带动水冷铜坩埚向下移动到熔炼开始时位置。打开排气电控截止阀23，使上下室破除真空，并恢复到常压状态。松开模壳锁紧机构14，打开锁紧密封机构，吊走上室9，取出铸件，完成浇注过程。After the titanium alloy casting is solidified, close the gas source electric control shut-off valve 21, open the upper and lower chamber communication electric control shut-off valve 18, and remove the pressure difference between the upper and lower chambers, so that the unsolidified alloy liquid in the riser pipe flows back into the crucible, and starts The crucible lifting mechanism 29 drives the water-cooled copper crucible to move down to the position when the smelting starts. Open the exhaust electric control stop valve 23 to break the vacuum in the upper and lower chambers and return to the normal pressure state. Unclamp the formwork locking mechanism 14, open the locking and sealing mechanism, lift the upper chamber 9, take out the casting, and complete the pouring process.
