技术领域 technical field
本实用新型有关一种铸锻成型装置，尤指一种将金属的铸造方法与锻压方法相互结合，一次性实现金属成型，将成型流程大大缩短，并可降低生产成本的铸锻成型装置。 The utility model relates to a casting and forging forming device, especially a casting and forging forming device which combines metal casting and forging methods to realize metal forming at one time, greatly shortens the forming process and reduces production costs.
背景技术 Background technique
传统小型金属配件会采用精密铸造或者精密模锻的工艺方式生产，例如运动器材(高尔夫球头、打击面)、壳状结构(电子部品机壳、表壳)、小型五金配件、汽车零组件等；其中，精密铸造首先要制作准备一铸模，其设有一模穴，该模穴具有预定成品的规格；接着，将蜡液注入该铸模的模穴以形成一蜡模；自该模穴取出该蜡模，再将该蜡模浸浆形成一高分子砂浆壳模；接着，加热使蜡模熔化流出该陶瓷壳外模；再将融熔金属液注入该陶瓷壳外模以形成一初胚。最后，将该初胚再经数道表面加工，即可制得预定规格的成品。 Traditional small metal accessories are produced by precision casting or precision die forging, such as sports equipment (golf heads, hitting surfaces), shell structures (electronic parts casings, watch cases), small hardware accessories, automotive components, etc. ; Among them, precision casting first needs to make and prepare a casting mold, which is provided with a mold cavity, and the mold cavity has the specifications of the predetermined finished product; then, inject the wax liquid into the mold cavity of the casting mold to form a wax model; take out the mold cavity from the mold cavity The wax pattern is dipped in slurry to form a polymer mortar shell mold; then, the wax pattern is heated to melt and flow out of the ceramic shell outer mold; and then molten metal is injected into the ceramic shell outer mold to form an embryo. Finally, the embryo is subjected to several surface processes to obtain a finished product with predetermined specifications.
其中，精密铸造中壳模制作周期长，工艺复杂，其铸造后的金属表面会产生松散且较厚的生成物(α-Ti)，其机械强度较差，且壳模为一次性使用无法重复使用。 Among them, the production cycle of the shell mold in precision casting is long and the process is complicated. The metal surface after casting will produce loose and thick product (α-Ti), which has poor mechanical strength, and the shell mold is for one-time use and cannot be repeated. use.
另外，精密模锻方式其制程首先选用由锻造用碳钢或合金钢制成的一金属块，接着使该金属块经过数个锻模的数次锻压处理。在锻造过程中，由于各锻模的模穴依序一连串形成形状变化，因此可逐渐使该金属块的外形轮廓同步锻压成对应形状的初胚。最后，将该初胚再经数道表面加工，即可制得预定规格的成品。 In addition, the manufacturing process of the precision die forging method first selects a metal block made of forging carbon steel or alloy steel, and then makes the metal block go through several forging processes with several forging dies. During the forging process, since the mold cavities of each forging die form a series of shape changes in sequence, the outline of the metal block can be gradually forged into a corresponding shape of the blank. Finally, the embryo is subjected to several surface processes to obtain a finished product with predetermined specifications.
虽然，该锻造成型的成品具有均匀且结构强度高等优点，但是由于锻造过程使用过多锻模数量，其容易导致开模及制造成本过高、不适合大量生产、不易制造复杂造型及锻模易因施压变形而必需经常更换等缺点。Although the forged finished product has the advantages of uniformity and high structural strength, due to the excessive number of forging dies used in the forging process, it will easily lead to high mold opening and manufacturing costs, and is not suitable for mass production. It is not easy to manufacture complex shapes and forging dies are easy. Disadvantages such as frequent replacement due to pressure deformation.

本实用新型的铸锻成型装置使用时，先提供一金属模具6，并将该金属模具6组装至该铸造室2的容置空间21内。提供一坩锅12，并将该坩锅12组装至该熔炼室1，且装填一金属物料(图未示)于该坩锅12内，再将该炉盖11盖合于该熔炼室1上方，而将该坩锅12封闭，并利用该真空系统5对该坩锅12内进行抽真空，其真空度0.3×10-1Pa~1.0×10-1Pa，本实用新型利用至少一真空泵(例如机械泵及鲁氏泵)，可由不同的真空泵的抽真空能力相互搭配，可达成高真空或低真空的需求；而装填于坩锅内的金属物料可为钛、钛合金(例如可为64钛)、铝合金或不锈钢。 When the casting and forging forming device of the present utility model is used, a metal mold 6 is provided first, and the metal mold 6 is assembled into the accommodation space 21 of the casting chamber 2 . Provide a crucible 12, assemble the crucible 12 into the melting chamber 1, and fill a metal material (not shown) in the crucible 12, and then cover the furnace cover 11 on the melting chamber 1 , and the crucible 12 is closed, and the vacuum system 5 is used to vacuumize the crucible 12, the vacuum degree is 0.3×10 -1 Pa ~ 1.0×10 -1 Pa, the utility model utilizes at least one vacuum pump ( Such as mechanical pump and Lushi pump), the vacuuming capacity of different vacuum pumps can be matched with each other to meet the needs of high vacuum or low vacuum; and the metal material filled in the crucible can be titanium, titanium alloy (for example, it can be 64 titanium), aluminum alloy or stainless steel.
再利用第二加热单元加热该金属模具6，使其温度为40℃至500℃。当坩锅内的真空度达0.3×10-1Pa~1.0×10-1Pa时，则停止该真空系统5对该坩锅12抽真空。藉由该气体提供系统3提供厌氧气体至该坩锅12内；此时，该坩锅12在真空度达0.3×10-1Pa~1.0×10-1Pa后，其坩锅12内充满厌氧气体(可以为氩气或氮气)，让该坩锅内形成无氧环境，在后续加热步骤时，可防止容置于坩锅12内的金属物料形成氧化。 Then use the second heating unit to heat the metal mold 6 to a temperature of 40°C to 500°C. When the vacuum degree in the crucible reaches 0.3×10 −1 Pa˜1.0×10 −1 Pa, the vacuum system 5 is stopped to evacuate the crucible 12 . The gas supply system 3 provides anaerobic gas into the crucible 12; at this time, the crucible 12 is filled with The anaerobic gas (which can be argon or nitrogen) makes the crucible form an oxygen-free environment, and prevents the metal materials contained in the crucible 12 from being oxidized during the subsequent heating step.
之后，利用第一加热单元13加热该坩锅12，加热温度达到该金属物料的熔点，以将该金属物料形成熔融状。例如，若置放于坩锅内的金属物料为钛合金，则加热温度须达1600℃至1800℃，才得以将金属物料完全形成熔融状。利用该真空系统5对该铸造室的金属模具6进行抽真空，其真空度达0.3×10-1Pa~1.0×10-1Pa，可让金属模具6形成无氧环境。 Afterwards, the first heating unit 13 is used to heat the crucible 12, and the heating temperature reaches the melting point of the metal material, so as to form the metal material into a molten state. For example, if the metal material placed in the crucible is a titanium alloy, the heating temperature must reach 1600°C to 1800°C to completely melt the metal material. The metal mold 6 of the casting chamber is vacuumed by the vacuum system 5, and the vacuum degree reaches 0.3×10 -1 Pa to 1.0×10 -1 Pa, so that the metal mold 6 can form an oxygen-free environment.
最后，将坩锅12内熔融状的金属物料经由该导管22充填至该金属模具6。此时，熔融状的金属物料其温度较高(若为钛合金其温度达约1600℃至1800℃)，而充填至该金属模具6后，因金属模具6的温度为40℃至500℃，具有降温作用让金属物料形成半固态，而完成铸造工序。之后，再启动该顶压系统4对该金属模具6进行锻造成型，利用该控制单元41控制该动力单元43，使该顶压模杆44朝该金属模具6位移并提供压力，以完成半固态成品。其中，该控制单元41可控制动力单元43施加的压力及时间的设定及调整。 Finally, the molten metal material in the crucible 12 is filled into the metal mold 6 through the conduit 22 . At this time, the temperature of the molten metal material is relatively high (if it is a titanium alloy, its temperature reaches about 1600°C to 1800°C), and after filling the metal mold 6, because the temperature of the metal mold 6 is 40°C to 500°C, It has a cooling effect to make the metal material form a semi-solid state and complete the casting process. After that, start the pressing system 4 again to forge the metal mold 6, use the control unit 41 to control the power unit 43, make the pressing mold rod 44 move towards the metal mold 6 and provide pressure to complete the semi-solid state finished product. Wherein, the control unit 41 can control the setting and adjustment of the pressure and time applied by the power unit 43 .
待冷却后则完成成品。其中，本实用新型所应用的产品运动器材(高尔夫球头、打击面)、壳状结构(电子部品机壳、表壳)、小型五金配件、汽车零组件等，且藉由本实用新型的成形装置，不仅在铸造工序中熔融及冷却金属物料时，提供无氧环境，更在锻造成型亦提供了无氧环境，可确保金属物料在铸造及锻造成型过程中不会形成氧化，让成品不易因氧化而形成松散的生成物，可提升成品的机械强度及延伸性。 After cooling, the finished product is completed. Among them, the product sports equipment (golf head, hitting surface), shell-like structure (electronic parts casing, watch case), small hardware accessories, auto parts, etc. applied by the utility model, and by the forming device of the utility model , not only provide an oxygen-free environment when melting and cooling metal materials in the casting process, but also provide an oxygen-free environment in forging molding, which can ensure that the metal materials will not form oxidation during casting and forging molding, so that the finished product is not easy to be oxidized And forming a loose product can improve the mechanical strength and extensibility of the finished product.
