Description

一种新型的浆体磨料射流系统 技术领域
本发明涉及一种新型的浆体磨料射流系统，特别适用于浆体磨料射流的切割。
技术背景
目前使用的水射流切割系统多为磨料射流，但由于系统问题，无论是前混合还是后混合磨料射流系统都存在磨料浓度不均匀的问题，从而影响切割质量，效率不高等问题。针对此问题，美国及国内一些研究者引入了浆体磨料水射流系统，改善了磨料浓度分布不均匀问题，但浆体磨料增压发生方法以及连续供料方法仍然有待于优化。
发明内容
技术问题：本发明的目的是克服现有技术问题中的不足之处，提供一种新型的浆体磨料射流系统，通过双作用活塞连接浆体增压腔与高压油腔，使分别独立的两个系统关联，从而实现浆体磨料的增压发生与连续供应，实现射流系统的均匀、稳定、连续的工作。
技术方案：本发明的新型的浆体磨料射流系统，包括高压油缸、与高压油缸设在同一中心线上的浆体增压缸，高压油缸和浆体增压缸内设有将其连为一体的双作用活塞，双作用活塞将高压油缸和浆体增压缸分为无杆腔A和有杆腔B，所述高压油缸的无杆腔A和有杆腔B的入口Y1、Y3分别连接与油压泵相连的电磁换向阀一，高压油缸的无杆腔A和有杆腔B的出口Y2、Y4分别连接与油箱相连的电磁换向阀二，所述浆体增压缸的无杆腔A和有杆腔B的入口M1、M3分别连接电磁换向阀三，电磁换向阀三的两个入口分别与制浆池和清水池相连，所述浆体增压缸的无杆腔A和有杆腔B的出口M2、M4分别与浆体磨料射流管相连。
所述的双作用活塞的两端活塞盘与活塞杆螺纹连接，活塞盘与活塞连杆的连接处设有一颗防松的内六角螺栓。
所述的双作用活塞的中间位置设有的行程开关触发凸台，当触发凸台与设置在高压腔或浆体增压腔外侧的行程开关重合时，行程开关被挤压按下，给控制器发出信号，电磁换向阀进行换向动作，活塞进行反向运动。
所述电磁换向阀一的出口与高压油缸无杆腔A和有杆腔B入口相连的管路上分别设有单向逆止阀。
所述电磁换向阀三的出口与浆体增压缸无杆腔A和有杆腔B入口连接的管路上分别设有单向逆止阀；所述浆体增压缸的无杆腔A和有杆腔B的出口与浆体磨料射流管相连的管路上分别设在单向逆止阀。
有益效果：由于采用了上述技术方案，本发明中的浆体增压腔与高压油腔设置在同一中心线上，由双作用活塞连接进行压力传递，两个腔体依次循环完成吸入与压出，根据行程开关的检测确保活塞在腔内完成循环运动，实现系统的连续。行程开关与高压油循环系统的两组电磁换向阀关联，确保其同时工作，给浆体增压腔提供稳定、连续的动力。通过双作用活 塞连接浆体增压腔与高压油腔，使分别独立的两个系统关联，从而实现浆体磨料的增压发生与连续供应，实现射流系统的均匀、稳定、连续的工作。与现有技术相比的主要优点有：
(1)将浆体增压射流系统与液压油循环系统设计成相对独立的两个系统，有效的避免了浆体在增压腔内与其他液体掺混的可能性。
(2)本系统采用双作用活塞，保证了浆体射流系统的稳定性与连续性。

具体实施方式
下面结合附图中的实施例对本发明作进一步的说明：
如图1所示，本发明的浆体磨料射流系统，主要由电磁换向阀一4、电磁换向阀二7、单向逆止阀5、高压油缸6、浆体增压缸9、双作用活塞8和电磁换向阀三10组成。所述的高压油缸6与浆体增压缸9设在同一中心线上，双作用活塞8的头分别设在高压油缸6和浆体增压缸9内，将其连为一体，双作用活塞8将高压油缸6和浆体增压缸9分为无杆腔A和有杆腔B，所述的双作用活塞8的两端活塞盘与活塞杆螺纹连接，活塞盘与活塞连杆的连接处设有一颗进行放松的内六角螺栓；所述的双作用活塞8的中间位置设有的行程开关触发凸台，当触发凸台与设置在高压腔或浆体增压腔外侧的行程开关重合时，行程开关被挤压按下，给控制器发出信号，电磁换向阀进行换向动作，活塞进行反向运动。所述高压油缸6的无杆腔A和有杆腔B的入口Y1、Y3分别连接与油压泵2相连的电磁换向阀一4，高压油缸6的无杆腔A和有杆腔B的出口Y2、Y4分别连接与油箱相连的电磁换向阀二7，所述电磁换向阀一4的出口与高压油缸6无杆腔A和有杆腔B入口相连的管路上分别设有单向逆止阀5。所述浆体增压缸9的无杆腔A和有杆腔B的入口M1、M3分别连接电磁换向阀三10，电磁换向阀三10的两个入口分别与制浆池和清水池相连，所述浆体增压缸9的无杆腔A和有杆腔B的出口M2、M4分别与浆体磨料射流管相连。所述电磁换向阀三10的出口与浆体增压缸9无杆腔A和有杆腔B入口连接的管路上分别设有单向逆止阀；所述浆体增压缸9的无杆腔A和有杆腔B的出口与浆体磨料射流管相连的管路上分别设在单向逆止阀。
将所述高压油缸6、浆体增压缸9和双作用活塞8固定在同一支架上，保证其工作时的稳 定。所述浆体增压腔分A、B两个腔体，每个腔体在末端分别设有入料口M1、M3与出料口M2、M4。高压油腔同样分为A、B两个腔体，每个腔体末端分别设有高压油入口Y1、Y3与出口Y2、Y4将高压油送回油箱。双作用活塞连杆轴线与行程开关置于同一平面，通过行程开关能清楚的确定活塞在高压油腔内的运动方向。
如图2(a)、图2(b)和图2(c)所示，所述双作用活塞8，两端活塞盘与活塞连杆螺纹连接，连杆连接处设有一颗内六角螺栓进行防松。
工作原理：所述电磁换向阀一4和电磁换向阀二7与行程开关相连接，通过由行程开关得到的信号同步控制电磁换向阀一4和电磁换向阀二7的开启与闭合，确保高压油腔无杆腔A和有杆腔B的正常运作。
工作过程：通电后高压油泵启动，电磁换向阀一4和电磁换向阀二7由初始位置运动至右端，由高压油泵将液压油通过电磁换向阀一4由入口Y3输送到高压油腔无杆腔A侧，双作用活塞向左运动，高压油腔有杆腔B内空气或液压油由出口Y2通过电磁换向阀二7输送回油箱。同时浆体增压腔有杆腔B通过入口M3将浆体吸入有杆腔B内，浆体增压腔无杆腔A进行浆体增压由出口M2输送至喷嘴，完成浆体射流。
根据行程开关检测到的信号同时改变电磁换向阀一4和电磁换向阀二7，此时液压油通过电磁换向阀由Y1输送至高压油腔B端，高压油腔无杆腔A内的液压油通过出口Y4电磁换向阀二7流回油箱。双作用活塞向右运动，浆体由入口M1吸入增压腔无杆腔A内，浆体增压腔有杆腔B开始进行浆体增压由出口M4输送至喷嘴。通过双作用活塞8的左右运动实现系统提供连续、稳定的浆体磨料射流，提高工作质量和效率。
切割完成后，调节电磁换向阀三10对浆体增压腔及管路进行清水清洗，防止磨料沉积堵塞系统，清洗完成后即可断电停机。
