Description
技术领域Technical Field
本发明涉及锻造技术领域，具体涉及一种锻件切边校正系统。The invention relates to the technical field of forging, and in particular to a forging trimming correction system.
背景技术Background Art
锻件的典型锻造工艺流程通常为：下料—压扁(弯曲)—预锻—终锻—切边—校正，传统工艺在锻造切边过程中容易受弯矩作用产生直线度变形，后续需要通过油压机点压校直，但是在校直过程中会产生诸多问题：(1)产生残余应力，影响产品精度；(2)热校正工序通常需要单独的精整设备和校正模具，不仅加大了投资，而且增加了工序和生产周期；(3)对于已经产生变形的锻件来说，热校正仅能起到一定的作用，不能完全消除变形。The typical forging process flow of forgings is usually: cutting - flattening (bending) - pre-forging - final forging - trimming - correction. The traditional process is prone to straightening deformation due to the bending moment during the forging and trimming process, and it needs to be straightened by hydraulic press. However, many problems will arise during the straightening process: (1) Residual stress is generated, affecting product accuracy; (2) The thermal correction process usually requires separate finishing equipment and correction molds, which not only increases investment, but also increases the process and production cycle; (3) For forgings that have already been deformed, thermal correction can only play a certain role and cannot completely eliminate the deformation.
因此，采用切边校正复合工艺，将切边和校正工序集中在一副模具中，在压力机的一次行程中完成产品的切边和校正工序，不仅可减少设备与模具的投资成本，提高生产效率，而且在切边过程中保证了产品直线度，更有利于提升产品精度。要在切边的同时实现校正功能，必须在切边的过程中给锻件施加一定的背压，使锻件在整个切边过程中都处于受压状态，从而控制锻件变形。早期有采用气缸和碟簧施加背压的方式，近几年出现用氮气弹簧代替碟簧来实现背压功能。Therefore, the trimming and correction composite process is adopted to concentrate the trimming and correction processes in one die, and complete the trimming and correction processes of the product in one stroke of the press. This can not only reduce the investment cost of equipment and molds and improve production efficiency, but also ensure the straightness of the product during the trimming process, which is more conducive to improving product accuracy. In order to realize the correction function while trimming, a certain back pressure must be applied to the forging during the trimming process, so that the forging is under pressure during the entire trimming process, thereby controlling the deformation of the forging. In the early days, cylinders and disc springs were used to apply back pressure. In recent years, nitrogen springs have been used instead of disc springs to realize the back pressure function.
但上述施加背压的方式都存在一定的缺陷，其中气缸控制方便，价格较低，但力量小不稳定，难以满足长轴类较大型锻件的背压需求；碟簧稳定，可以达到所需压力，但由于变形小，要满足切边行程就需要多片组合，因此结构庞大，要求有足够的安装空间；氮簧稳定且力量大，但由于频繁压缩会造成自身发热严重，易损坏，需要经常更换，加上氮簧本身的高价格，因此使用成本很高。However, the above-mentioned methods of applying back pressure all have certain defects. Among them, the cylinder is easy to control and has a low price, but the power is small and unstable, and it is difficult to meet the back pressure requirements of larger forgings such as long shafts; the disc spring is stable and can reach the required pressure, but due to its small deformation, a combination of multiple pieces is required to meet the trimming stroke, so the structure is bulky and requires sufficient installation space; the nitrogen spring is stable and powerful, but due to frequent compression, it will cause severe self-heating, is easy to damage, and needs to be replaced frequently. In addition, the high price of the nitrogen spring itself makes its cost very high.
此外，上述三种方式还有个共同的缺点：一旦设计完成，可实现的背压就基本恒定，不能针对不同产品进行调节，因此缺乏柔性，不适合小批量多品种产品的切边设备使用。In addition, the above three methods have a common disadvantage: once the design is completed, the achievable back pressure is basically constant and cannot be adjusted for different products. Therefore, it lacks flexibility and is not suitable for use as trimming equipment for small batches of multi-variety products.
发明内容Summary of the invention
因此，本发明要解决的技术问题在于克服现有技术中锻件在进行切边校正时背压基本恒定、不能针对不同产品进行调节、缺乏柔性的技术缺陷，从而提供一种可根据不同产品来调节背压、具有柔性、适用性强的锻件切边校正系统。Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that the back pressure of forgings is basically constant during trimming correction, cannot be adjusted for different products, and lacks flexibility, thereby providing a forging trimming correction system that can adjust the back pressure according to different products, is flexible, and has strong applicability.

进一步地，所述液压垫柱塞缸设置有两排，每排所述液压垫柱塞缸均等间距分布，且数量不相等。如图2所示，其中一排设置有五个液压垫柱塞缸，另一排设置有七个液压垫柱塞缸，两排液压垫柱塞缸呈梯形分布，若需要对较短的锻件进行校正切边，则可以使用中间的十个液压垫柱塞缸，若需要对较长的锻件进行校正切边，则可以使用全部液压垫柱塞缸，这样的设计可以根据不同的需求来选择使用不同的液压垫柱塞缸组合，从而可以通过配置液压垫柱塞缸的个数和分布，来针对不同产品有效施加背压力。Furthermore, the hydraulic pad plunger cylinders are arranged in two rows, and the hydraulic pad plunger cylinders in each row are evenly spaced and unequal in number. As shown in FIG2 , one row is provided with five hydraulic pad plunger cylinders, and the other row is provided with seven hydraulic pad plunger cylinders. The two rows of hydraulic pad plunger cylinders are arranged in a trapezoidal shape. If it is necessary to correct and trim the shorter forgings, the ten hydraulic pad plunger cylinders in the middle can be used. If it is necessary to correct and trim the longer forgings, all hydraulic pad plunger cylinders can be used. Such a design can select different combinations of hydraulic pad plunger cylinders according to different needs, so that the back pressure can be effectively applied to different products by configuring the number and distribution of hydraulic pad plunger cylinders.

Further, the mounting assembly includes a first die frame 4 and a second die frame 7 which are arranged on both axial sides of the trimming correction assembly 5; specifically, the first die frame 4 is arranged at the lower end of the upper pad 3, the first trimming correction assembly 5 is installed on the first die frame 4, the rod passes through the first die frame 4 and is connected with the first trimming correction assembly 5, the slider 2 is suitable for driving the upper pad 3, the first die frame 4 and the first trimming correction assembly 5 to move up and down in the vertical direction, so as to drive the first trimming correction assembly 5 to a predetermined position suitable for trimming correction, and then apply back pressure to the first trimming correction assembly 5 through the hydraulic pad plunger cylinder, so that the first trimming correction assembly 5 is corrected while trimming; the second trimming correction assembly 5 is installed on the second die frame 7, the second die frame 7 is arranged on the lower pad 8, and the second die frame 7 is provided with a second hydraulic cylinder for transporting the flash of the forging after trimming to a predetermined position, and the second hydraulic cylinder is an ejection cylinder, and the ejection cylinder transmits the ejection force to a designated component in the second trimming correction assembly 5 through a rod system structure.
在本实施例中，所述导向组件设于所述第一模架4和所述第二模架7之间。进一步地，所述导向组件包括对称分布在所述切边校正组件5两侧的一对导向柱6，所述第一模架4朝向第二模架7的端面上安装有与所述导向柱6适配的导向套，所述第一模架4在所述第一驱动组件的作用下沿所述导向柱6往复运动。导向组件的设计不仅起到导向作用，还起到支撑连接作用，从而提高了系统结构的稳定性。In this embodiment, the guide assembly is arranged between the first mold frame 4 and the second mold frame 7. Further, the guide assembly includes a pair of guide posts 6 symmetrically distributed on both sides of the trimming correction assembly 5, and a guide sleeve adapted to the guide posts 6 is installed on the end surface of the first mold frame 4 facing the second mold frame 7, and the first mold frame 4 reciprocates along the guide posts 6 under the action of the first driving assembly. The design of the guide assembly not only plays a guiding role, but also plays a supporting and connecting role, thereby improving the stability of the system structure.
在本实施例中，所述温度传感器用于监测所述液压垫柱塞缸与所述蓄能器之间的油液温度。由于液压垫柱塞缸和蓄能器之间油液的频繁流动易造成油液升温，因此温度传感器的设计可以使系统实时监控油温，并形成闭环控制，一旦检测到油温过高，则自动更换液压垫柱塞缸和蓄能器内部循环的油液，使油温维持在合理的运行区间内。In this embodiment, the temperature sensor is used to monitor the oil temperature between the hydraulic pad plunger cylinder and the accumulator. Since the frequent flow of oil between the hydraulic pad plunger cylinder and the accumulator easily causes the oil temperature to rise, the design of the temperature sensor enables the system to monitor the oil temperature in real time and form a closed-loop control. Once the oil temperature is detected to be too high, the oil circulating inside the hydraulic pad plunger cylinder and the accumulator is automatically replaced to maintain the oil temperature within a reasonable operating range.
当需要对锻件进行切边校正时，首先根据锻件的大小、尺寸来选择需要提供背压力的液压垫柱塞缸的使用个数，进而来控制液压垫柱塞缸提供的背压力的大小，然后滑块2下降，带动上垫板3、第一模架4以及第一切边校正组件5下降至预定位置并实现切边校正。这样的结构设计可以通过配置液压垫柱塞缸的个数和分布，来针对不同产品有效施加背压力，使系统具有柔性、适合多种产品的切边校正，从而提高了系统的适用性以及实用性。When trimming correction is required for forgings, the number of hydraulic pad plunger cylinders that need to provide back pressure is first selected according to the size and dimensions of the forgings, and then the size of the back pressure provided by the hydraulic pad plunger cylinder is controlled. Then the slider 2 descends, driving the upper pad 3, the first die frame 4 and the first trimming correction assembly 5 to descend to the predetermined position and realize trimming correction. Such a structural design can effectively apply back pressure to different products by configuring the number and distribution of hydraulic pad plunger cylinders, making the system flexible and suitable for trimming correction of various products, thereby improving the applicability and practicality of the system.
实施例2Example 2
与实施例1不同的是，如图3所示，所述液压装置设置为两组，每组所述液压装置中的所述液压垫柱塞缸与一个蓄能器连接，两组所述液压装置提供的背压力不同，因此不同组的液压垫柱塞缸可具备不同的压力，从而对复杂形状锻件的不同部位施加的背压力也不同，实现了更加柔性化的切边校正功能。Different from Example 1, as shown in Figure 3, the hydraulic device is arranged in two groups, and the hydraulic pad plunger cylinder in each group of the hydraulic device is connected to an accumulator. The back pressures provided by the two groups of the hydraulic devices are different, so different groups of hydraulic pad plunger cylinders may have different pressures, thereby applying different back pressures to different parts of complex-shaped forgings, thereby achieving a more flexible trimming correction function.
