本发明涉及汽车零件制造领域,特别是涉及一种汽车弹簧座的制造方法和 设备。 背景技术  The present invention relates to the field of automotive parts manufacturing, and more particularly to a method and apparatus for manufacturing a spring seat for an automobile. Background technique
随着经济危机、 能源危机和环境问题在全球范围内加剧, 汽车制造业的发 展开始向经济、 节能、 环保、 安全的方向转变, 这就要求汽车零件制造过程中 降低生产成本和减少资源的消耗。  As the economic crisis, energy crisis and environmental problems intensify globally, the development of the automobile manufacturing industry has begun to shift to economic, energy saving, environmental protection and safety, which requires lower production costs and reduced resource consumption in the manufacturing of automotive parts.
在汽车的各种零件制造中, 汽车弹簧座的制造需要采用两套不同的模具。 参见图 1 , 示出了汽车零件中的弹簧座的结构图。 从图 1中可以看出, 汽车弹 簧座的中心有一孔,在孔的下方还具有翻边的结构。 为了制造出弹簧座的这一 结构,现有技术采用的是对钢材料分别进行成形和沖孔翻边两个工艺过程来完 成。 由于成形和翻边是通过两个工艺过程来完成的, 所以对于弹簧座的制造就 需要两套不同的模具,分别用于将钢材料沖压形成弹簧座的主体结构和对主体 结构成形的钢材料沖孔形成翻边结构。  In the manufacture of various parts of automobiles, the manufacture of automotive spring seats requires the use of two different sets of dies. Referring to Figure 1, a structural view of a spring seat in an automotive part is shown. As can be seen from Figure 1, the car spring seat has a hole in the center and a flanged structure below the hole. In order to fabricate this structure of the spring seat, the prior art employs two processes of forming and punching the steel material separately. Since the forming and flanging are performed by two processes, two different sets of molds are required for the manufacture of the spring seat, which are respectively used for stamping the steel material into a main body structure of the spring seat and a steel material for forming the main body structure. Punching forms a flanged structure.
由于现有技术需要采用两套模具和两步工序才能形成汽车弹簧座的完整 结构, 所以在制造时需要消耗的模具材料、 钢材原料和能源等资源都较大, 从 而导致汽车弹簧座的制造过程生产成本过高、 资源消耗过大。 发明内容  Since the prior art requires two sets of molds and two steps to form the complete structure of the automobile spring seat, the resources of the mold material, the steel material and the energy source which are consumed during manufacture are large, and the manufacturing process of the automobile spring seat is caused.

为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施 例中的附图, 对本申请实施例中的技术方案进行清楚、 完整地描述, 显然, 所 描述的实施例仅是本申请一部分实施例, 而不是全部的实施例。基于本申请中 的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其 他实施例, 都属于本申请保护的范围。 For a better understanding of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. It is a partial embodiment of the present application, and not all of the embodiments. Based on this application All other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.
发明人经过长期的发明研究发现,由于现有技术中汽车弹簧座制造中沖压 成形的都是采用冷沖压来完成, 而在冷沖压的条件下, 钢板的延展性很差, 这 会导致汽车弹簧座的主体结构和翻边结构在同时成形时坯料钢板容易出现拉 裂, 因此, 即使将现有的成形主体结构的模具和成形翻边结构的模具连接在一 起, 直接对坯料钢板进行沖压也难以形成完整的汽车弹簧座结构, 并且会产生 很多废品。  The inventor discovered through long-term invention that, due to the prior art, the stamping forming of the automobile spring seat is completed by cold stamping, and under the condition of cold stamping, the ductility of the steel sheet is very poor, which leads to the automobile spring. When the main structure and the flanged structure of the seat are simultaneously formed, the blank steel sheet is prone to cracking. Therefore, even if the existing mold for forming the main body structure and the mold for forming the flanged structure are joined together, it is difficult to directly press the blank steel sheet. Forms a complete car spring seat structure and produces a lot of waste.
基于发明人的上述发现, 本发明的主要思想是: 分别在原成形汽车弹簧座 主体结构的凹模与凸模内部, 安装了成形翻边结构的凸模模芯与凹模模芯,从 而形成了凸模组合和凹模组合, 其中, 该凸模模芯、 凹模模芯、 凸模、 凹模是 单独的结构; 在成形汽车弹簧座时, 先将坯料钢板加热, 然后将加热过的坯料 钢板放置于凹模组合的分模面,再将凸模组合沖压入凹模组合。 由于这一过程 中采用了热沖压成形, 所以增强了坯料钢板的延展性, 这样再通过模具内部的 特定结构, 就可以利用凸模和凹模成形汽车弹簧座的主体结构, 利用凸模模芯 和凹模模芯成形汽车弹簧座的翻边结构,从而可以实现在一次沖压过程中利用 一套模具同时完成汽车弹簧座的主体结构和翻边结构的成形。  Based on the above findings of the inventors, the main idea of the present invention is: a male mold core and a female mold core having a formed flange structure are respectively installed in the concave mold and the convex mold of the main structure of the original spring car seat, thereby forming a a combination of a punch and a die, wherein the punch core, the die core, the punch, and the die are separate structures; when forming the spring seat of the automobile, the billet steel plate is first heated, and then the heated billet is heated The steel plate is placed on the parting surface of the die combination, and the punch combination is punched into the die combination. Since the hot stamping is used in this process, the ductility of the blank steel sheet is enhanced, so that the main structure of the automobile spring seat can be formed by the punch and the die by the specific structure inside the mold, and the punch core is utilized. And the die core forming the flange structure of the automobile spring seat, so that the main body structure of the automobile spring seat and the forming of the flange structure can be completed simultaneously by using one set of molds in one stamping process.
下面结合附图,通过实施例来详细说明本发明的一种汽车弹簧座的制造方 法和设备的具体实现方式。 参见图 2,示出了本发明中汽车弹簧座的制造方法实施例 1的基本流程图。 在本实施例中, 可以包括以下步骤:  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a specific implementation of a method and apparatus for manufacturing a car spring seat of the present invention will be described in detail by way of embodiments with reference to the accompanying drawings. Referring to Fig. 2, there is shown a basic flow chart of Embodiment 1 of the method of manufacturing a car spring seat of the present invention. In this embodiment, the following steps may be included:
步骤 201、 在预设的加热温度下加热坯料钢板。  Step 201: Heating the billet steel sheet at a preset heating temperature.
其中, 在热沖压加工系统中, 坯料钢板是置于加热炉。 由于通常热沖压需 要将钢板加热到其奥氏体化温度以上, 因此预设的加热温度通常不会低于 700 摄氏度。 这种情况下, 还可以在加热炉内充满氮气等保护气体, 这样可以防止 钢板在加热时氧化。这样步骤 301具体可以包括: 将坯料钢板置于充满氮气的 加热炉中加热至所述坯料钢板的奥氏体化温度,并在所述坯料钢板达到所述奥 氏体化温度时, 将所述坯料钢板进行保温。 其中, 优选将坯料钢板加热到其奥 氏体化温度以上的 10~50°C , 保温的时间优选为 5分钟。 Among them, in the hot stamping processing system, the billet steel sheet is placed in a heating furnace. Since hot stamping usually requires heating the steel sheet above its austenitizing temperature, the preset heating temperature is usually not lower than 700 degrees Celsius. In this case, it is also possible to fill the heating furnace with a protective gas such as nitrogen, which prevents the steel sheet from being oxidized upon heating. The step 301 may specifically include: heating the billet steel plate in a heating furnace filled with nitrogen to an austenitizing temperature of the billet steel sheet, and when the billet steel sheet reaches the austenitizing temperature, The billet steel plate is kept warm. Among them, it is preferred to heat the billet steel sheet to its base The temperature is 10 to 50 ° C above the denaturation temperature, and the holding time is preferably 5 minutes.
需要说明的是, 所选用的坯料钢板的不同, 其奥氏体化温度也不同, 所以 就需要根据坯料钢板来预设加热炉内的加热温度也是不同。其中,坯料钢板的 奥氏体化温度与该钢板的成分有关。  It should be noted that the austenitizing temperature of the selected blank steel plate is also different, so it is necessary to preset the heating temperature in the heating furnace according to the blank steel plate. Among them, the austenitizing temperature of the billet steel plate is related to the composition of the steel sheet.

Further, the parting surface 803 of the die 701 is located at the top end of the upper surface of the die 701.
步骤 203、 将所述凸模组合沖压入所述凹模组合, 以便所述坯料钢板在所 述凸模与所述凹模之间的空隙内形成所述汽车弹簧座的主体结构,并在所述凸 模模芯与所述凹模模芯之间的空隙内形成所述汽车弹簧座的翻边结构。 Step 203, stamping the punch combination into the die combination, so that the blank steel plate is in the Forming a main body structure of the automobile spring seat in a gap between the punch and the die, and forming a car spring seat in a gap between the punch core and the die core Flanging structure.

And flanged structure. Two preferred stamping methods of the present embodiment are described in detail below.
参见图 10, 示出了本实施例中步骤 203的具体实施方式 1的流程图。 本 实施方式可以包括:  Referring to Fig. 10, a flow chart of a specific embodiment 1 of step 203 in the present embodiment is shown. This embodiment may include:
步骤 1001、 将所述凹模模芯拉至所述凹模模芯的顶端位于所述凹模的分 模面的状态。  Step 1001: Pull the die core to a state in which the tip end of the die core is located on the die face of the die.
在本实施方式中, 所述凸模模芯固定在所述凸模内部, 所述凸模模芯的顶 端平面与所述凸模的分模面位于同一平面;所述凹模模芯滑动连接在所述凹模 内部, 所述凹模顶端的活动范围为所述凹模的分模面和底部之间。  In this embodiment, the punch core is fixed inside the punch, and a top end plane of the punch core is in the same plane as a parting surface of the punch; the die core is slidingly connected Inside the die, the range of motion of the die tip is between the split face and the bottom of the die.
其中, 由于凸模模芯是固装在凸模上的, 所以凸模组合实际上一块完整的 模具配件, 该固装所成的凸模组合与图 4所示结构相同。 而凹模模芯与凹模之 间则采用的是滑动连接, 凹模模芯可沿凹模下部分的空心结构内移动。在每次 沖压开始时, 该凹模模芯拉至其顶端位于凹模的分模面的位置,也即图 7所示 的位置。  Wherein, since the punch core is fixed on the punch, the punch combination is actually a complete mold part, and the fixed punch combination is the same as that shown in Fig. 4. A sliding connection is used between the die core and the die, and the die core can move along the hollow structure of the lower portion of the die. At the beginning of each stamping, the die core is pulled to the position where the top end is located on the parting surface of the die, i.e., the position shown in FIG.
步骤 1002、 将所述凸模组合沖压至所述凸模模芯压入所述凹模模芯的状 态,以便所述坯料钢板在所述凸模模芯与所述凹模模芯之间的空隙内形成所述 汽车弹簧座的翻边结构。  Step 1002, stamping the male mold assembly into a state in which the male mold core is pressed into the female mold core, so that the blank steel sheet is between the male mold core and the female mold core A flanged structure of the automobile spring seat is formed in the gap.
由于凹模模芯处于凹模分模面的位置, 所以凸模组合沖压至凹模组合时, 凸模模芯会先沖压入凹模模芯中, 此时凹模与凸模的分模面重合,但凸模还未 沖压入凹模。 所以, 此时坯料钢板只成形了翻边结构, 还未成形主体结构。  Since the die core is at the position of the die split surface, when the punch is combined into the die combination, the punch core is first punched into the die core, and the die face of the die and the punch is Coincident, but the punch has not been punched into the die. Therefore, at this time, the billet steel sheet is formed only with a flanged structure, and the main body structure has not yet been formed.
步骤 1003、 将所述凹模模芯拉至所述凹模模芯的顶端位于所述凹模的底 部的状态。 在凸模模芯沖压入凹模模芯之后,翻边结构已成形, 此时将凹模模芯下移 至凹模的底部, 以便凸模组合可以继续向下沖压, 以便凸模可以沖压入凹模内 部。 Step 1003: Pull the die core to a state in which the top end of the die core is located at the bottom of the die. After the punch core is punched into the die core, the flange structure has been formed, and the die core is moved down to the bottom of the die so that the punch combination can continue to be punched down so that the punch can be punched in. Inside the die.
步骤 1004、 将所述凸模组合沖压至所述凸模压入所述凹模的状态, 以便 所述坯料钢板在所述凸模与所述凹模之间的空隙内形成所述汽车弹簧座的主 体结构。  Step 1004, stamping the punch combination into a state in which the punch is pressed into the die, so that the blank steel plate forms the automobile spring seat in a gap between the punch and the die. main structure.
需要说明的是,在本实施方式中,模具在沖压时需要动作的模具部分有凸 模组合和凹模模芯, 因此, 设备需要为这两个模具部分分别提供动力。 本实施 方式中提供了两种动力提供方式。  It is to be noted that, in the present embodiment, the mold portion to be operated at the time of punching has a convex mold combination and a female mold core, and therefore, the apparatus needs to separately supply power to the two mold portions. Two power supply modes are provided in this embodiment.
在第一种动力提供方式中,所述设备可以采用弹簧和单缸液压机提供所述 模具沖压的动力,所述凸模组合与液压机压缸相连,所述凹模模芯与弹簧相连。 凹模模芯依靠弹簧的弹力支撑位于凹模分模面,凸模组合在活动横梁的带动下 沖压, 先沖压到凹模模芯中成形翻边结构, 然后继续沖压, 将凹模模芯的弹簧 压缩, 从而在将凹模模芯压至凹模底部的同时, 将凸模沖压入凹模内部, 从而 完成主体结构的成形。  In a first type of power supply, the apparatus may provide power for stamping of the mold using a spring and a single cylinder hydraulic press, the male mold combination being coupled to a hydraulic press cylinder, the female mold core being coupled to the spring. The die core is supported by the elastic force of the spring on the die parting surface, and the punch combination is punched by the movable beam, first punched into the die core to form the flange structure, and then the stamping is continued, and the die core is pressed. The spring is compressed to press the punch into the interior of the die while pressing the die core to the bottom of the die, thereby completing the formation of the body structure.
在第二种动力提供方式中,所述设备可以采用双缸液压机提供所述模具沖 压的动力, 所述凸模组合与所述液压机活动横梁相连, 所述凹模模芯与所述液 压机下缸相连。 液压机下缸带动凹模模芯上移至分模面位置, 凸模组合在活动 横梁带动下沖压, 先沖压到凹模模芯中成形翻边结构, 然后继续沖压, 在将凹 模模芯压至凹模底部的同时,将凸模沖压入凹模内部,从而完成主体结构的成 形。  In a second power supply mode, the apparatus may provide power for the die stamping by using a two-cylinder hydraulic press, the punch combination being connected to the hydraulic cross member, the die core and the hydraulic press lower cylinder Connected. The lower cylinder of the hydraulic machine drives the die core to move to the position of the parting surface, and the punch combination is punched by the movable beam, first punching into the die core to form the flange structure, and then continuing to punch, and pressing the die core At the same time as the bottom of the die, the punch is punched into the interior of the die to complete the formation of the body structure.
上述图 10采用的凹模模芯可移动的沖压方式, 下面将说明凸模模芯可移 动的沖压方式。  The above-described die 10 is a movable stamping method for the die core, and a punching method in which the punch core can be moved will be described below.
参见图 11 , 示出了本实施例中步骤 203的具体实施方式 2的流程图。 本 实施方式可以包括:  Referring to Fig. 11, a flow chart of a specific embodiment 2 of step 203 in the present embodiment is shown. This embodiment may include:
步骤 1101、 将所述凸模沖压入所述凹模, 以便所述坯料钢板在所述凸模 与所述 模之间的空隙内形成所述汽车弹簧座的主体结构。  Step 1101, stamping the punch into the die so that the blank steel plate forms a main structure of the automobile spring seat in a gap between the punch and the die.
在本实施方式中, 所述凹模模芯固定在所述凹模内部, 所述凹模模芯的顶 端平面与所述凹模的底部位于同一平面;所述凸模模芯活动连接在所述凸模内 部。 In this embodiment, the die core is fixed inside the die, and a top end plane of the die core is in the same plane as a bottom of the die; the punch core is movably connected Inside the convex mold Ministry.
其中, 由于凹模模芯是固装在凹模上的, 所以凹模组合实际上一块完整的 模具配件。 而凸模模芯与凸模之间则采用的是可拆卸的滑动连接, 凸模模芯可 沿凸模的空心结构内移动,并且可以分离,实现凸模与凸模模芯分别进行沖压。  Among them, since the die core is fixed on the die, the die combination is actually a complete die fitting. The embossed core and the punch are separated by a detachable sliding joint. The punch core can be moved along the hollow structure of the punch and can be separated to realize stamping of the punch and the punch core respectively.
由于凸模模芯与凸模可分别进行沖压, 所以凸模组合沖压至凹模组合时, 首先将凸模沖压入凹模中, 此时凸模模芯还未沖压,坯料钢板只成形了主体结 构, 还未成形翻边结构。  Since the punch core and the punch can be stamped separately, when the punch is combined into the die, the punch is first punched into the die, and the punch core is not yet stamped, and the blank steel plate only forms the main body. Structure, not yet formed flanged structure.
步骤 1102、 将所述凸模模芯沖压入所述凹模模芯, 以便所述坯料钢板在 所述凸模模芯与所述凹模模芯之间的空隙形成所述汽车弹簧座的翻边结构。  Step 1102, stamping the punch core into the die core, so that the gap between the punch core and the die core forms a turn of the car spring seat Edge structure.
其中, 凸模模芯沖压时, 穿过凸模中的圓柱形空心结构, 沖压到凹模模芯 中, 从而成形翻边结构。  Wherein, when the punch core is stamped, it passes through the cylindrical hollow structure in the punch and is punched into the die core to form the flange structure.
需要说明的是,在本实施方式中,模具在沖压时需要动作的模具部分有凸 模和凸模模芯, 因此, 设备需要为这两个模具部分分别提供动力。 本实施方式 中提供了两种动力提供方式。  It is to be noted that, in the present embodiment, the mold portion that the mold needs to operate at the time of punching has a convex mold and a male mold core, and therefore, the apparatus needs to separately supply power to the two mold portions. Two power supply modes are provided in this embodiment.
在第一种动力提供方式中,所述设备可以采用弹簧和单缸液压机提供所述 模具沖压的动力, 所述凸模模芯与液压机压缸相连, 所述凸模与弹簧相连。 凸 模先依靠弹簧的弹力沖压至凹模中, 完成主体结构, 凸模模芯在液压机压缸的 带动下沖压, 再沖压到凹模模芯中成形翻边结构。  In a first type of power supply, the apparatus may provide power for stamping of the mold using a spring and a single cylinder hydraulic machine, the male mold core being coupled to a hydraulic press cylinder, the male mold being coupled to the spring. The punch is first stamped into the die by the spring force of the spring to complete the main structure. The punch core is punched by the hydraulic cylinder and then punched into the die core to form the flange structure.
在第二种动力提供方式中,所述设备可以采用双缸液压机提供所述模具沖 压的动力, 所述凸模与所述液压机活动横梁相连, 所述凸模模芯与所述液压机 上缸相连。 凸模在活动横梁的带动下沖压到 模中完成主体结构的成形, 然后 凸模模芯在液压机上缸带动下沖压到凹模模芯中完成翻边结构的成形。  In a second power supply mode, the apparatus may provide power for stamping of the mold by using a two-cylinder hydraulic machine, the punch is connected to the movable beam of the hydraulic machine, and the punch core is connected to the upper cylinder of the hydraulic machine. .

通过上述图 10和图 11的沖压方式,可以实现汽车弹簧座的主体结构和翻 边结构的一次成形过程。  By the above-described stamping methods of Figs. 10 and 11, the primary forming process of the main body structure and the flanged structure of the automobile spring seat can be realized.
接着返回图 2, 步骤 203执行完成之后, 本实施例可以结束。  Returning to Fig. 2, after the execution of step 203 is completed, the embodiment can be ended.
采用本实施例的技术方案,由于分别在原成形汽车弹簧座主体结构的 模 与凸模内部, 安装了成形翻边结构的凸模模芯与凹模模芯, 并且采用热沖压成 形工艺增强了坯料钢板的延展性, 所以通过模具内部特定的结构, 就可以利用 凸模和凹模成形汽车弹簧座的主体结构,利用凸模模芯和凹模模芯成形汽车弹 簧座的翻边结构,从而可以实现在一次沖压过程中利用一套模具同时完成汽车 弹簧座的主体结构和翻边结构的成形。 参见图 12, 示出了本发明中汽车弹簧座的制造方法实施例 2的流程图, 本实施例中在图 2所示的方法实施例 1基础上,在步骤 203之后,还可以包括: 步骤 1201、 在所述模具中对所述汽车弹簧座进行冷却; 所述模具上具有 冷却系统; According to the technical solution of the embodiment, the punch core and the die core of the forming flange structure are respectively installed in the mold and the punch mold of the main structure of the automobile spring seat, and the blank is enhanced by the hot stamping forming process. The ductility of the steel plate, so through the specific structure inside the mold, the main structure of the automobile spring seat can be formed by the punch and the die, and the car shell can be formed by the punch core and the die core. The flanged structure of the spring seat can realize the forming of the main structure and the flange structure of the automobile spring seat by using one set of molds in one stamping process. Referring to FIG. 12, a flowchart of a second embodiment of a method for manufacturing a car spring seat according to the present invention is shown. In this embodiment, based on the method embodiment 1 shown in FIG. 2, after step 203, the method may further include: 1201, cooling the automobile spring seat in the mold; the mold has a cooling system;
由于热沖压时坯料钢板的温度较高,所以在模具中汽车弹簧座的主体结构 和翻边结构都已成形之后, 需要对形成的汽车弹簧座进行冷却。  Since the temperature of the billet steel sheet is high at the time of hot stamping, it is necessary to cool the formed automobile spring seat after the main structure and the flange structure of the automobile spring seat have been formed in the mold.
由于热沖压中钢板温度通常能够达到该钢板的奥氏体化温度, 所以,通过 热沖压过程后的冷却可以很容易使机械零件形成马氏体组织钢结构。具有马氏 体组织钢结构的钢制品是一种超高强钢, 可以在使用时承受更高的受力强度。 这样, 形成马氏体组织钢结构的汽车弹簧座就能够承受高强度的推拉力。  Since the temperature of the steel sheet in hot stamping can usually reach the austenitizing temperature of the steel sheet, the mechanical parts can easily form a martensitic structure steel structure by cooling after the hot stamping process. A steel product having a martensitic steel structure is an ultra-high strength steel that can withstand higher tensile strength during use. Thus, the automobile spring seat forming the martensitic structure steel structure can withstand high-strength push-pull force.
在冷却时,可以直接在凸模组合和凹模组合所组成的模具上安装一个冷却 系统, 该汽车弹簧座在该冷却系统中冷却速度需要达到 15 °C/s以上。  When cooling, a cooling system can be mounted directly on the mold consisting of a combination of punch and die, which requires a cooling rate of 15 ° C/s or more in the cooling system.
