Abstract

本发明连续送料挤压成型机构，将板材送入该机构中，直到板材的端头全部进入工作位置，通过操作压模向下挤压板材，在压模和凹模的作用下，加工出需要的工件形状。本发明能够通过滚轮对输入的板材进行导向和支撑，使得整个机构能够在连续的板材上进行间歇式的冲压加工。配合对应的冲裁模，能够在完成挤压成型之后，接着一次动作完成冲裁的动作，将已经挤压成型的工件冲裁下来。本发明将成型和剪裁合而为一，避免了传统的分步骤加工的加工方式费时费力的问题，能够在挤压成型的之后完成冲裁加工，提高了加工效率。

Description

连续送料挤压成型机构
技术领域
本发明涉及一种挤压成型机构，具体涉及一种连续送料挤压成型机构。
背景技术
冲裁模是冲压生产中不可缺少的工艺装备，良好的模具结构是实现工艺方案的可靠保证。冲压零件的质量好坏和精度高低，主要取决于冲裁模的质量和精度。冲裁模结构是否合理、先进，有直接影响到生产效率及冲裁模本身的使用寿命和操作的安全、方便性等。由于冲裁件形状、尺寸、精度和生产批量及生产条件不同，冲裁模的结构类型也不同。冲裁模主要用于各种板材的落料与冲裁，模具的工作部位是凸、凹模的刃口，刃口工作时承受冲击力、剪切力、弯曲力，以及剪切材料的强烈摩擦力，因而对冲裁模的性能要求主要是指对模具刃口的性能要求。冷冲裁模具可分为薄板冲裁模（板厚≤1.5mm）和厚板冲裁模（板厚＞1.5mm）两种。对于钣金件的加工，要求模具用钢具有高的耐磨性。但是薄板件本身材料容易剪切加工，在加工中，往往会预先将钣金件剪切成符合加工大小的尺寸，再进行挤压成型，得到需要的工件，这种方式将剪裁和挤压分离进行，无形之中增加了加工时间，降低了加工效率。
发明内容
本发明的目的在于提供一种连续送料挤压成型机构，改变现有的加工方式，采用送料整体的冲压成型的方式进行加工，将冲压成型和剪切放在一起进行，在保证加工精度的同时，提高了加工效率。
为达到上述目的，本发明的技术方案是：连续送料挤压成型机构，包括底座，所述底座上设有竖向的凹模，所述凹模的上端面为弧面；所述底座上还设有两个滚轮架，所述两个滚轮架对称设置在凹模的两侧，所述滚轮架的顶端铰接有一个传动滚轮；所述底座上还包括一个压模，所述压模位于凹模的正上方，所述压模的下方设有与凹模的弧面配合的凸面。
采用上述技术方案时，将板材送入该机构中，直到板材的端头全部进入工作位置，通过操作压模向下挤压板材，在压模和凹模的作用下，加工出需要的工件形状。本发明能够通过滚轮对输入的板材进行导向和支撑，使得整个机构能够在连续的板材上进行间歇式的冲压加工。配合对应的冲裁模，能够在完成挤压成型之后，接着一次动作完成冲裁的动作，将已经挤压成型的工件冲裁下来。本发明将成型和剪裁合而为一，避免了传统的分步骤加工的加工方式费时费力的问题，能够在挤压成型的之后完成冲裁加工，提高了加工效率。
进一步，所述滚轮架通过沉头螺钉固定在底座上。
进一步，所述凹模的下端固定有贯穿底座的顶杆。
进一步，所述滚轮架上设有安装键块。设置安装键块，能够通过安装键块安装适合的剪裁凸模，适应不同的加工需求。
附图说明
下面结合附图和具体实施方式对本发明作进一步详细的说明：
图1是本发明连续送料挤压成型机构实施例的结构示意图。
具体实施方式
如图1所示，本发明连续送料挤压成型机构，包括底座1，底座1上设有竖向的凹模2，凹模2的上端面为弧面。底座1上还设有两个滚轮架3，两个滚轮架3对称设置在凹模2的两侧，滚轮架3的顶端铰接有一个传动滚轮4；底座1上还包括一个压模5，压模5位于凹模2的正上方，压模5的下方设有与凹模2的弧面配合的凸面。滚轮架3通过沉头螺钉6固定在底座1上。凹模2的下端固定有贯穿底座1的顶杆7。滚轮架3上设有安装键块8。设置安装键块8，能够通过安装键块8安装适合的剪裁凸模，适应不同的加工需求。
本发明中，将板材送入该机构中，直到板材的端头全部进入工作位置，通过操作压模5向下挤压板材，在压模5和凹模2的作用下，加工出需要的工件形状。本发明能够通过滚轮4对输入的板材进行导向和支撑，使得整个机构能够在连续的板材上进行间歇式的冲压加工。配合对应的冲裁模，能够在完成挤压成型之后，接着一次动作完成冲裁的动作，将已经挤压成型的工件冲裁下来。本发明将成型和剪裁合而为一，避免了传统的分步骤加工的加工方式费时费力的问题，能够在挤压成型的之后完成冲裁加工，提高了加工效率。
以上的仅是本发明的优选实施方式，应当指出，对于本领域的技术人员来说，在不脱离本发明构思的前提下，还可以作出若干变形和改进，这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的实用性。
