Description

高强度钢零件的热成形、冲孔和切边一体化工艺及模具 Hot forming, punching and trimming integrated process and mold for high-strength steel parts

技术领域 technical field

本发明涉及高强度钢、先进高强度钢和超高强度钢冲压零件的热冲压成形及冲孔、切边工艺和模具,属于高强度钢板金零件的成形技术领域。The invention relates to hot stamping forming, punching, trimming process and mold of high-strength steel, advanced high-strength steel and ultra-high-strength steel stamping parts, and belongs to the technical field of forming high-strength steel plate gold parts.

背景技术 Background technique

当前,在汽车制造领域,人们对高安全性、低自重和良好的燃油经济性的需求已经成为技术进步的重要推动因素。制造商们通过引入新的安全概念和轻量化的车身结构等措施使消费者的愿望得以实现。尤其是在车身结构方面,通过对高强度钢、先进高强度钢和超高强度钢的使用,提高了汽车的碰撞性能同时也实现了轻量化的要求。但是随着钢材强度的提高,延伸率下降,材料的成形性能也大大降低,成形过程中还容易产生破裂、起皱、尺寸难以控制和形状不良等问题,传统的冷冲压成形工艺已不能满足技术和生产发展的需要。At present, in the field of automobile manufacturing, people's demand for high safety, low dead weight and good fuel economy has become an important driving factor for technological progress. Manufacturers are making consumers' wishes come true by introducing new safety concepts and lightweight body structures. Especially in terms of body structure, through the use of high-strength steel, advanced high-strength steel and ultra-high-strength steel, the crash performance of the car is improved and the requirement of lightweight is also achieved. However, with the increase of steel strength, the elongation rate decreases, and the formability of the material is also greatly reduced. During the forming process, problems such as cracking, wrinkling, difficult to control the size and poor shape are prone to occur. The traditional cold stamping forming process can no longer meet the technical requirements. and production development needs.

近几年,国内外学者开发出一种新的高强度、超高强度钢板热冲压成形工艺,该工艺使高强度钢和超高强度钢板料在加热炉中被加热到奥氏体化温度(900~950℃),并在奥氏体区保持5分钟,然后将板料转移到压力机,在冲压模具中同时进行冲压成形和淬火,使成形零件获得100%马氏体组织。该工艺能够在提高碰撞性能和疲劳强度的同时降低汽车结构件的重量。In recent years, scholars at home and abroad have developed a new hot stamping process for high-strength and ultra-high-strength steel sheets, which heats high-strength steel and ultra-high-strength steel sheets to the austenitizing temperature ( 900~950℃), and keep it in the austenite zone for 5 minutes, then transfer the sheet to the press, and perform stamping forming and quenching in the stamping die at the same time, so that the formed parts can obtain 100% martensite structure. The process can reduce the weight of automotive structural parts while improving crash performance and fatigue strength.

中国专利文献CN101288889公开了一种《超高强度钢板热冲压成型模具》,该模具包括上模座和固定在上模座上的凸模、下模座和固定在下模座上的凹模,凹模中设有冷却水通道,冷却水通道与一个冷却水循环系统相连接。Chinese patent document CN101288889 discloses a "ultra-high-strength steel plate hot stamping die", which includes an upper mold base and a punch fixed on the upper mold base, a lower mold base and a concave mold fixed on the lower mold base, and A cooling water channel is arranged in the mold, and the cooling water channel is connected with a cooling water circulation system.

中国专利文献CN1829813公开了一种《热成形法与热成形构件》,对于特定成分的钢板加热至奥氏体点温度(Ac3)以上并保持后,进行最终制品形状的成形,在成形中或者从成形后的成形温度的冷却之时,到达成形构件的马氏点温度(Ms点)的冷却速度在临界冷却速度以上,并且,以从Ms点到200℃的平均冷却速度为25~150℃/s冷却而进行淬火处理。Chinese patent document CN1829813 discloses a kind of "hot forming method and hot forming member". After heating a steel plate with a specific composition above the austenite point temperature (Ac3) and maintaining it, the final product shape is formed. During forming or from When cooling the forming temperature after forming, the cooling rate to the Martens point temperature (Ms point) of the formed component is above the critical cooling rate, and the average cooling rate from the Ms point to 200 °C is 25~150 °C/ s cooling and quenching treatment.

对于尺寸精度要求较高、热成形零件上有通孔或热成形零件带有压料凸缘的情况下,必须对热成形零件进行二次加工。在冷冲压工序中,一般是利用冲压模具进行冲孔、修边等二次加工,但在热冲压工序中利用常规模具结构进行二次加工极为困难;采用冷冲压模具对淬火后强度提高的成形部件进行切边或冲孔加工需要很大的加工载荷,金属模将被损坏或寿命缩短,对于超高强度钢板的热成形零件甚至无法用冷冲压模具进行加工。In the case of high dimensional accuracy requirements, through-holes on thermoformed parts or press flanges on thermoformed parts, secondary processing of thermoformed parts is necessary. In the cold stamping process, the stamping die is generally used for secondary processing such as punching and trimming, but it is extremely difficult to use a conventional die structure for secondary processing in the hot stamping process; Trimming or punching of components requires a large processing load, and the metal die will be damaged or its life shortened. For hot-formed parts of ultra-high-strength steel plates, it is even impossible to process with cold stamping dies.

为了使热成形的高强度零件符合相应的尺寸精度和形状要求,目前均采用五轴激光切割技术进行冲孔和修边,但是激光切边或切孔效率低,一条热冲压生成线往往需要数套激光切边或切孔线与之配套,另外,每套激光切边或切孔线均需要相应的夹具对零件进行定位、装夹,因而设备占地面积大、设备投资多、生产成本高。另外,激光切边或切孔后,热成形零件的切边或孔边会带有一些熔融金属凝固后所形成的金属颗粒,需要后续的打磨工序把金属废料去除,导致热成形零件的生产周期长,限制了热冲压技术的推广应用。使用激光切边或切孔时,完成时间受零件大小及孔数量的限制,最简单的零件从零件固定到切边夹具到切割完成需要30秒以上,对于复杂零件可能需要几分钟。In order to make hot-formed high-strength parts meet the corresponding dimensional accuracy and shape requirements, five-axis laser cutting technology is currently used for punching and trimming. However, the efficiency of laser trimming or cutting holes is low, and a hot stamping production line often requires several A set of laser edge trimming or hole cutting line is matched with it. In addition, each set of laser edge trimming or hole cutting line needs corresponding fixtures to position and clamp the parts, so the equipment occupies a large area, equipment investment is large, and production costs are high. . In addition, after laser trimming or hole cutting, the trimming or hole edge of the thermoformed part will have some metal particles formed after the solidification of molten metal, which requires a subsequent grinding process to remove the metal waste, resulting in a production cycle of thermoformed parts Long, which limits the popularization and application of hot stamping technology. When using laser trimming or hole cutting, the completion time is limited by the size of the part and the number of holes. The simplest part takes more than 30 seconds from the part to the trimming fixture to the completion of cutting. It may take several minutes for complex parts.

中国专利文献CN2617549公开了一种《新型热冲孔、切边模具》,用于锻件的热冲孔、切边模具,该专利所公开的模具只能利用压力机的滑块运动,完成单一的冲孔、切边,而不能用于成形、切边或冲孔复合,另外,该模具结构是用于钢块锻造,属于体积成形领域,不能用于属于板料成形领域的高强度板料的冲孔或切边。Chinese patent document CN2617549 discloses a "new hot punching and trimming die", which is used for hot punching and trimming dies for forgings. The die disclosed in this patent can only use the slide block movement of the press to complete a single Punching, trimming, but not for forming, trimming or punching compound, in addition, the mold structure is used for steel block forging, belongs to the field of volume forming, and cannot be used for high-strength sheet metal belonging to the field of sheet metal forming Punch or trim.

中国专利文献CN101326022公开了一种《用于液压冲孔的组合冲头》,用于在液压胀形的构件中形成孔。该组合冲头是在零件液压胀形完成后,让冲头退到模具内部,利用高压液体作为动力,将需要冲孔部位切成几块,从而完成冲孔过程。该工艺及结构只适用于液压胀形的低强度钢板,不能用于高强度钢零件的成形及冲孔。Chinese patent document CN101326022 discloses a "combined punch for hydraulic punching", which is used to form holes in hydraulic bulging components. After the hydraulic bulging of the part is completed, the combined punch retreats the punch to the inside of the mold, and uses the high-pressure liquid as power to cut the part to be punched into several pieces to complete the punching process. This process and structure are only suitable for hydraulic bulging low-strength steel plates, and cannot be used for forming and punching high-strength steel parts.

切边工序需要将围绕高强度钢待切边热成形零件9周边的废料全部切下,为了保证切边工序的顺利实施,简化切边工具的设计,对切边工具采用如图10所示的分块形式。高强度钢零件的周边轮廓可能是任意曲线,下切边工具的分块数量根据高强度钢零件的复杂程序决定,上切边工具与下切边工具的分块数量相同。切边工具的所有分块中有几个要超出高强度钢零件的边界线(图3中的点划线),保证切边后可以将废料分割成几块,便于废料的取出。切边工具的厚度一般根据成形的高强度零件的壁厚确定,切边工具的厚度是零件壁厚的1.5~4.0倍,对于薄板成形的高强度零件,取上限,对于中厚板成形的高强度零件,取下限。切边过程中,上切边工具通过与压料板1中相应的安装孔进行导向,下切边工具通过与成形凹模5中相应的安装孔进行导向。The edge trimming process needs to cut off all the waste around the high-strength steel hot-formed part 9 to be edge trimmed. In order to ensure the smooth implementation of the edge trimming process and simplify the design of the edge trimming tool, the edge trimming tool is used as shown in Figure 10. chunked form. The peripheral contour of the high-strength steel part may be an arbitrary curve. The number of segments of the lower trimming tool is determined according to the complex program of the high-strength steel part. The number of segments of the upper trimming tool is the same as that of the lower trimming tool. Several of all the blocks of the trimming tool will exceed the boundary line of the high-strength steel part (dotted line in Fig. 3), to ensure that the scrap can be divided into several pieces after trimming, so as to facilitate the removal of the scrap. The thickness of the trimming tool is generally determined according to the wall thickness of the formed high-strength parts. The thickness of the trimming tool is 1.5 to 4.0 times the wall thickness of the part. For high-strength parts formed from thin plates, the upper limit is taken. Strength parts, take the lower limit. During the trimming process, the upper trimming tool is guided through the corresponding mounting hole in the binder plate 1 , and the lower trimming tool is guided through the corresponding mounting hole in the forming die 5 .

单块的切边工具一般长度较大,如果用一个油缸为切边工具施加切边力,将导致切边力不足或切边工具在切边过程中因受力不均导致偏斜,加快切边工具及模具的磨损速度。为了解决这种问题,如图4和图6所示,根据上切边工具2、上切边工具13或下切边工具3、12的大小,采用两个以上的上模油缸或下模油缸为切边工具提供切边力,而且油缸要沿着切边工具均布,保证能为切边工具提供足够大的切边力,而且保证切边工具受力均衡,避免偏斜。为上切边工具2提供动力的多个上模油缸19的上油孔19a连接在一起,下油孔19b连接在一起,保证上模的多个油缸可以同时动作;为上切边工具13提供动力的多个上模油缸14的上油孔14a连接在一起,下油孔14b连接在一起,保证上模的多个油缸可以同时动作;为下切边工具3提供动力的多个下模油缸6的上油孔6a连接在一起,下油孔6b连接在一起,保证多个下模油缸可以同时动作;为下切边工具12提供动力的多个下模油缸10的上油孔10a连接在一起,下油孔10b连接在一起,保证多个下模油缸可以同时动作。The single-piece edge trimming tool is generally long.
