铝合金铸件为了提高力学性能、耐腐蚀性能、稳定尺寸、改善切削加工和焊接等加工性能，一般会进行热处理工艺。A319铝合金也需要通过热处理来进一步提高铸件的机械性能和其它使用性能，具体有以下几个方面：1）消除由于铸件结构（如璧厚不均匀、转接处厚大）等原因使铸件在结晶凝固时因冷却速度不均匀所造成的内应力；2）提高合金的机械强度和硬度，改善金相组织，保证合金有一定的塑性和切削加工性能、焊接性能；3）稳定铸件的组织和尺寸，防止和消除高温相变而使体积发生变化；4）消除晶间和成分偏析，使组织均匀化。In order to improve mechanical properties, corrosion resistance, stable dimensions, and improve processing properties such as cutting and welding, aluminum alloy castings generally undergo heat treatment. The A319 aluminum alloy also needs heat treatment to further improve the mechanical properties and other performance of the casting. The specific aspects are as follows: 1) Eliminate the internal stress caused by the uneven cooling rate of the casting during crystallization and solidification due to the casting structure (such as uneven wall thickness, thick transition) and other reasons; 2) Improve the mechanical strength and hardness of the alloy, improve the metallographic structure, and ensure that the alloy has certain plasticity, machinability, and welding performance; ) Eliminate intergranular and component segregation, and make the structure homogeneous.

After actual processing, it was found that during the cooling process of the A319 aluminum alloy casting after quenching, a certain degree of warping deformation will occur on both sides of the casting, which greatly affects the process performance of the casting. Therefore, in order to solve the above problems, it is necessary to develop a clamping device to prevent the warping deformation of the casting during the cooling process.

具体实施方式Detailed ways
为了使本领域技术人员更好的理解本发明，以下结合参考附图并结合实施例对本发明作进一步清楚、完整的说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below in conjunction with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
如图1至图3所示，一种铝合金铸件热处理防曲翘变形的夹紧装置，包括一块长度与铸件1长度相同的长方体基板2，在基板2的顶面上开设有沿其长度方向设置的通长凹型槽3，通长凹型槽3的槽口分别位于基板2的顶面及两个侧面上，通长凹型槽3的长度和铸件1的长度相同，宽度比铸件1的宽度略宽，一方面放置铸件1的时候便于装卸，另一方面也不会对铸件1的冷却造成影响；基板2采用45钢铸造而成，基板2及其上通长凹型槽3的设计既有固定铸件1的作用，使铸件1在移动过程中不会发生意外偏移，同时又对铸件1起到很好的支撑与保护作用；其中，长方体基板2的长、宽、高分别为1317.62mm、480mm、250mm，通长凹型槽3的长、宽、深分别为1317.62mm、256mm、90mm，则通长凹型槽3的槽底厚度为60mm。As shown in Figures 1 to 3, a clamping device for heat treatment of aluminum alloy castings to prevent warping and warping includes a cuboid base plate 2 with the same length as the casting 1. On the top surface of the base plate 2, there is a full-length concave groove 3 arranged along its length direction. The notches of the full-length concave groove 3 are located on the top surface and two sides of the base plate 2 respectively. 1 is affected by cooling; the base plate 2 is cast from 45 steel, and the design of the base plate 2 and its upper long concave groove 3 not only has the function of fixing the casting 1, so that the casting 1 will not accidentally shift during the movement, but also plays a good role in supporting and protecting the casting 1; among them, the length, width, and height of the cuboid base plate 2 are 1317.62mm, 480mm, and 250mm respectively, and the length, width, and depth of the long concave groove 3 are 1317.62mm, 256mm, respectively. mm, 90mm, then the groove bottom thickness of the long concave groove 3 is 60mm.
基板2上通长凹型槽3的槽底上开设有六个形状面积大小不同的贯穿洞口4，六个贯穿洞口4沿通长凹型槽3长度方向依次排列设置；六个贯穿洞口4的设计能够使铸件1在进行水冷的过程中水可以从基板2的底部通过这些洞口进入，直接对铸件1的冷却起到很大程度的影响，可以加快铸件1中间部位的冷却速度，再一个是六个贯穿洞口4面积大小设计成不一样的目的是为了保证基板2的整体刚度。The base plate 2 is provided with six through-holes 4 with different shapes and areas on the bottom of the groove 3, and the six through-holes 4 are arranged in sequence along the length direction of the through-long concave groove 3; the design of the six through-holes 4 enables the casting 1 to enter through these holes from the bottom of the base plate 2 during the water cooling process, which directly affects the cooling of the casting 1 to a large extent, and can speed up the cooling speed of the middle part of the casting 1. the overall stiffness.
通长凹型槽3两端的槽底部位进行了加厚处理，加厚厚度为20mm，也就是该处的槽底厚度为80mm，因为铸件1在冷却过程中由于结构特殊，总是薄的部分冷得快，厚的部分冷得慢，造成左右两边的冷却速度比中间部位的冷却速度快，铸件1内部不同的冷却速度会造成过渡区因应力集中产生畸变和开裂倾向，且冷却速度越快，冷却越不均匀，产生的应力越大，铸件1的变形也越大，所以在通长凹型槽3的左右两端的槽底进行了加厚处理，此处和铸件1的对应位置直接接触，水冷时不会过多影响该处，所以大大减少了此处的冷却速度，对铸件1冷却速度的均衡起到了很重要的作用。The groove bottom at both ends of the long concave groove 3 has been thickened to 20 mm, that is, the thickness of the groove bottom at this place is 80 mm. Because the casting 1 has a special structure during the cooling process, the thin part is always cooled quickly, and the thick part is cooled slowly, so that the cooling speed on the left and right sides is faster than that in the middle part. Different cooling speeds inside the casting 1 will cause distortion and cracking tendencies in the transition zone due to stress concentration. The greater the deformation, the thicker the groove bottom at the left and right ends of the through-long concave groove 3, which is in direct contact with the corresponding position of the casting 1, and will not affect this place too much during water cooling, so the cooling rate here is greatly reduced, which plays a very important role in the balance of the cooling rate of the casting 1.
通长凹型槽3中间的槽底部位也进行了加厚处理，加厚厚度为20mm，也就是该处的槽底厚度为80mm，和左右两端槽底的加厚作用不同的是此处加厚的目的是为了对铸件1起到一定程度的支撑作用，如果中间不进行支撑的加强，则会使铸件1在冷却时的曲翘变形相对加重，所以此处的加厚支撑对铸件1的变形也起到了重要的作用。The groove bottom in the middle of the full-length concave groove 3 is also thickened. The thickness of the thickening is 20mm, that is, the thickness of the groove bottom at this place is 80mm. The thickening effect is different from the thickening effect of the groove bottom at the left and right ends. The purpose of thickening here is to play a certain degree of support for the casting 1. If the support is not strengthened in the middle, the warping deformation of the casting 1 will be relatively aggravated during cooling, so the thickened support here also plays an important role in the deformation of the casting 1.
基板2的底面上固定有两条沿其长度方向设置的通长加强筋5，通长加强筋5的设置进一步的提高了基板2的强度；通长加强筋5的长度为1317.62mm、宽度为70mm、高度为100mm。The bottom surface of the base plate 2 is fixed with two full-length reinforcing ribs 5 arranged along its length direction, and the arrangement of the full-length reinforcing ribs 5 further improves the strength of the base plate 2; the length of the full-length reinforcing ribs 5 is 1317.62 mm, the width is 70 mm, and the height is 100 mm.
基板2的其中一端位于通长凹型槽3两侧的位置分别开设有沿基板2长度方向设置的方形槽6；由于铸件1并不是对称结构，在发生变形时其中一侧比另一侧的变形严重，为了提高基板2发生变形严重一侧的刚度，在该侧开了两个并不贯穿基板2的方形槽6，大大提升了该侧的刚度；方形槽6的槽底和通长凹型槽3与铸件1接触的平面在同一水平线上，方形槽6的长度、宽度、数量、深度是经过多次实验对比得出的，且发现不同的槽的数量和深度对结构刚度的影响是不同的，最终将方形槽6的长度设计为270mm、深度设计为70mm、宽度设计为30mm，方形槽6的端部设计为半径为15mm的圆角设计，方形槽6的外侧槽边距离基板2的外侧边的距离设计为70mm；开槽增加刚度的设计既提升了基板2的结构性能，也对结构轻量化设计提供了便利，便于生产加工。One of the ends of the base plate 2 is located at the two sides of the full-length concave groove 3 and is respectively provided with a square groove 6 arranged along the length direction of the base plate 2; since the casting 1 is not a symmetrical structure, one side is more severely deformed than the other side when deformation occurs. The depth was obtained after several experiments and comparisons, and it was found that the number and depth of different grooves have different effects on the structural rigidity. Finally, the length of the square groove 6 was designed to be 270 mm, the depth to 70 mm, and the width to 30 mm. The end of the square groove 6 was designed to have a rounded corner design with a radius of 15 mm. The distance between the outer edge of the square groove 6 and the outer edge of the substrate 2 was designed to be 70 mm. processing.
基板2顶面的两端端部分别可拆连接有横跨通长凹型槽3两侧设置的压板7，压板7与基板2之间通过螺钉8连接，具体是：基板2的两端分别开设有四个螺钉通孔9，每块压板7的四角处分别开设有四个螺钉孔，压板7置于基板2上后，使得压板7上的四个螺钉孔与基板2上的四个螺钉通孔9对齐，最后用螺钉8将二者固定连接即可，压板7与基板2配合对中间的铸件1起到夹紧作用，且便于装卸。压板7的长度为480mm、宽度为180mm、厚度为25mm，压板7的长度与基板2的宽度相同，以便于螺钉8的装卸。压板7在夹紧过程中由于受到的力很大，可能会随着铸件1发生曲翘变形，所以在压板7上进行了加强筋的设计，具体是在压板7的顶面固定有两条分置于压板7两端且横跨通长凹型槽3两侧设置的加强短筋10，加强短筋10的长度为480mm、宽度为62mm、厚度为10mm，这样的设计大大减少了压板7在夹紧过程中发生的变形，大大提升了压板7的使用寿命；压板7的材料选用45钢，刚度和硬度既满足夹紧装置的使用要求，也有很好的耐高温性能。为了满足夹紧装置的性能，螺钉8选用M18的螺钉，并使用垫片可填补不规则性，增大接触面积，减小压力，防止松动，保护零件和螺丝。The two ends of the top surface of the substrate 2 are respectively detachably connected with the pressure plate 7 arranged across the two sides of the long concave groove 3. The pressure plate 7 and the base plate 2 are connected by screws 8, specifically: the two ends of the base plate 2 are respectively provided with four screw holes 9, and the four corners of each pressure plate 7 are respectively provided with four screw holes. The casting 1 plays a clamping role and is convenient for loading and unloading. The length of the pressing plate 7 is 480mm, the width is 180mm, and the thickness is 25mm. The length of the pressing plate 7 is the same as the width of the base plate 2, so as to facilitate the loading and unloading of the screw 8. Due to the large force received by the pressing plate 7 during the clamping process, it may warp and warp with the casting 1. Therefore, the design of the reinforcing ribs is carried out on the pressing plate 7. Specifically, two short reinforcing ribs 10 are fixed on the top surface of the pressing plate 7. They are arranged at both ends of the pressing plate 7 and across the two sides of the long concave groove 3. The length of the short reinforcing ribs 10 is 480 mm, the width is 62 mm, and the thickness is 10 mm. The service life of the plate 7; the material of the pressure plate 7 is 45 steel, the rigidity and hardness not only meet the use requirements of the clamping device, but also have good high temperature resistance. In order to meet the performance of the clamping device, M18 screws are selected for screw 8, and gaskets can be used to fill irregularities, increase the contact area, reduce pressure, prevent loosening, and protect parts and screws.
进一步的，本实施例还提供了上述铝合金铸件热处理防曲翘变形的夹紧装置的使用方法，具体包括如下步骤：Further, this embodiment also provides a method for using the above-mentioned clamping device for heat treatment of aluminum alloy castings to prevent warping and deformation, which specifically includes the following steps:
S1：将基板2放置于水平地面上；S1: placing the substrate 2 on a level ground;
S2：将铸件1放置于基板2上的通长凹型槽3中，铸件1的两端与基板2的两端对齐；S2: Place the casting 1 in the long concave groove 3 on the substrate 2, and align the two ends of the casting 1 with the two ends of the substrate 2;
