Abstract

一种高效率色浆调色泵，包括具有绕轴周向布置的缸体（1）及与缸体配合的柱塞（2），所述缸体与柱塞的密封为涨硬配合密封，即缸体与柱塞的密封件为向柱塞膨胀的密封件（4，5，6，7），柱塞与密封件接触部分为硬质材料（3，31）。由于该高效率色浆调色泵中使用滚轮与斜盘的滚动摩擦副，因此减少了摩擦力，此外，柱塞与密封件接触部位通过增加硬度增加了耐磨性。

Description

一种高效率色浆调色泵 技术领域
本发明属于全自动调色机领域，具体涉及全自动调色机中的高效率调色泵。
背景技术
全自动调色机，一般由电脑主机、显示器、调色软件、调色机组成。全自动是相较于传统的手动调色来说的，因为手动调色机的操作步骤一般是先用手拉起泵体到一定高度然后打开阀门把色浆注入到基础漆桶中，而全自动调色机则通过预装在电脑中的调色软件控制调色机来执行各种动作以达到把色浆精确的注入到涂料目的。使用全自动调色机的优点是省时省事，不容易出错，而且能够达到非常高的精度。全自动调色机与全自动震荡机，全自动旋转机等油漆混匀设备一起构成了主流商店调色系统。目前高端全自动调色机主要由发达国家生产，但国产品牌依靠相对稳定的质量和低廉的价格，在涂料混匀机和手动调色机领域获得了巨大成功，并且正在正在研发高端的全自动电脑调色机。专利号为201210180754.0，专利名称为调色机的色浆定量供应装置的发明专利申请，就是利用斜盘轴向柱塞泵的原理，设计的高效率色浆调色泵。由于调色色浆对液压油的污染较敏感，该高效率调色泵对斜盘轴向柱塞泵的摩擦副进行了改进，将滑靴与斜盘的滑动摩擦副，改进为滚轮与斜盘的滚动摩擦副；考虑到斜盘轴向柱塞泵的柱塞，受到的是轴向、径向及旋转等方向的复杂合力，所以，对柱塞进行热处理时，进行调质处理，以达到高强度和高韧性的适当配合，这样的热处理方式，通过油膜润滑可以使用，直接使用在高效率调色泵上，进行干摩擦，柱塞磨损就过大，使用寿命就很短，不能正常使用，所以将斜盘轴向柱塞泵的柱塞与缸孔配合的油膜润滑摩擦副，改进为活塞与缸孔配合的干摩擦副；但是，活塞与缸孔配合的干摩擦副对于铁红、铁黄这样的含有矿物染料的色浆，活塞磨损也比较大，仍然不能达到反复正常工作155万次，打出1万 升的色浆，寿命5年的技术要求。
发明内容
为了解决高效率色浆调色泵的活塞与缸孔磨损大的问题，本发明提供一种柱塞与缸孔磨损小的高效率色浆调色泵，具体就是：
一种高效率色浆调色泵，包括具有绕轴周向布置的缸体及与缸体配合的柱塞，所述缸体与柱塞的密封为涨硬配合密封，缸体与柱塞的密封件为向柱塞膨胀的密封件，柱塞上与密封件接触部位为硬质材料。
所述柱塞上与密封件接触部位为硬质材料，柱塞整体或者柱塞整体表面为硬质材料。
所述柱塞上与密封件接触部位为硬质材料，限于柱塞与密封件接触部位设环状硬质材料。
所述接触部位设环状硬质材料，为柱塞上固定镶嵌套设硬质材料或者柱塞上包覆硬质材料。
所述硬质材料，为渗氮处理金属、离子软氮化处理金属、硬金属材质、陶瓷材料、玻璃材料之一。
所述渗氮处理金属，为GCr15经表面渗碳淬火硬度大于HRC55的硬质材料。
所述涨硬配合密封，为两个向柱塞膨胀的密封件沿柱塞轴向串联设置，两个密封件之间的距离大于等于柱塞行程。
所述两个密封件之间的间隙填充润滑材料。
所述润滑材料为润滑脂。
所述向柱塞膨胀的密封件为O型圈、波纹管、锲型环或者泛塞封。
所述泛塞封为加填料泛塞封。
所述填料为碳纤维或者玻璃纤维。
所述柱塞为GCr15经表面渗碳淬火硬度大于HRC55的柱塞。
所述泛塞封向柱塞施压的弹簧侧面为连续面。
所述向柱塞施压的弹簧侧面为连续面，弹簧为金属波纹管、金属环状涨管、弹簧箍、网状环胀管或者为螺旋弹簧环之一。
由于高效率色浆调色泵将斜盘轴向柱塞泵的滑靴与斜盘的滑动摩擦副，改进为滚轮与斜盘的滚动摩擦副，而滚动摩擦力比滑动摩擦力小的多，所以高效率色浆调色泵滚轮与斜盘的滚动摩擦力对柱塞受力的影响非常小，本专利就是滚轮与斜盘的滚动摩擦副，所以本专利柱塞的受力就比较简单，可以将柱塞与密封件接触部位通过增强硬度而增加耐磨性，多次实验证明，只要硬度大于调质处理的柱塞硬度，就能够增强耐磨损性能，具体耐磨的程度，要看性价比。

具体实施方式
下文的描述以及附图说明，示出了本发明示例性方案。附图是示意图，仅仅与本发明相关的部件被清楚的示出，本领域技术人员根据描述和附图，能够理解未被示出的部件的结构及连接关系。
下面根据本发明的附图，描述本发明的具体结构。一种高效率色浆调色泵，包括具有绕轴周向布置的缸体1及与缸体1配合的柱塞2，缸体1与柱塞2的密封为涨硬配合密封，即缸体1与柱塞2的密封件为向柱塞2膨胀的密封件，柱塞2与密封件接触部位为硬质材料。
所述的硬质材料，为硬度大于调质处理的柱塞硬度，只要柱塞硬度大于调质处理的硬度，就能够增强耐磨损性能。所述向柱塞2膨胀的密封件，机械接触密封就行。
所述柱塞2上与密封件接触部位为硬质材料，是指柱塞2整体或者柱塞2整体表面为硬质材料。这样，柱塞的整体为耐磨材料，或者柱塞整体的表面作硬化处理，可以喷涂、电镀、热处理等将表面硬化而耐磨。
所述柱塞2上与密封件接触部位为硬质材料，限于柱塞与密封件接触部位设环状硬质材料。
所述柱塞2上与密封件接触部位设环状硬质材料，可以是柱塞2上环状设硬质材料。此时，柱塞杆可以进行调质处理，当包覆硬质材料3价格高时，可以减少包覆硬质材料的用量，降低成本。
柱塞2上环状设硬质材料，可以为柱塞上包覆硬质材料3，如图20-21所示，图中硬质材料突出柱塞2表面，但是，电镀或者该部分进行热处理的柱塞2表面，实际上是不能或者不容易显示突出；包覆硬质材料3可以是喷涂、电镀、焊接等现有方式使柱塞2上包覆硬质材料3，实现包覆硬质材料3与密封件接触，达到高强度和高韧性的配合，增强耐磨性。
所述柱塞2与密封件接触部位设环状硬质材料，也可以是指柱塞2上固定镶嵌套设硬质材料31，如图22-23所示，图中硬质材料置于柱塞2的环形槽内，硬质材料外径与柱塞外径相同，这样插入缸孔部分的柱塞杆呈柱体状，有利于对柱塞2定位，这不是唯一的方式，事实上，硬质材料外径可以略大于或者小于柱塞外径，这样也可以实现本发明；在柱塞杆的环形槽内镶嵌套设管状材料的方式很多，以现有的方式套设就行。这样插入缸孔部分的柱塞杆呈柱体状，有利于对柱塞2定位。
所述硬质材料，为渗氮处理金属、离子软氮化处理金属、硬金属材质、陶瓷材料、玻璃材料等，当然，立方氮化硼等超硬材料也行。
渗氮处理金属，可以为GCr15经表面渗碳淬火硬度大于HRC55的硬质材料，这样的方式，性价比高。
所述涨硬配合密封，为两个向柱塞2膨胀的密封件沿柱塞2轴向串联设置，两个密封件之间的距离大于等于柱塞2行程。这样即避免了泄漏，由于一个密封件与柱塞2接触的部位，另一个密封件不能重复接触，这就避免了重复摩擦，减少了磨损。
所述两个密封件之间的间隙填充润滑材料。这样利用两个密封件之间的间隙作为储存润滑材料的密闭容器。所述润滑材料为润滑脂。润滑脂俗称润滑黄油，极微量的黄油不会污染调色色浆，就避免了调色色浆的污染。
向柱塞2膨胀的密封件可以为O型圈4(图1、2)、波纹管5(图3、4)、锲型环6(图5、6)。
向柱塞2膨胀的密封件也可以如图7-12、14-15、17-18所示，密封件为泛塞封7；泛塞封7为加填料泛塞封，所用填料为碳纤维或者玻璃纤维，碳纤维或者玻璃纤维加在容纳弹簧的U型密封外形材料内，容纳弹簧的U型密封外形材料一般为聚四氟材料，当然也可以为其它材料。
由于柱塞2为GCr15经表面渗碳淬火硬度大于HRC55的柱塞2。这样设置的6个柱塞2的高效率调色泵，能够保证能反复正常工作155万次，打出1万升的色浆，寿命能够达到5年的时间，是性价比比较高的方式。
所述泛塞封7向柱塞2施压的弹簧侧面为连续面，这样就避免原有的齿形弹簧通过唇侧边将柱塞摩擦出沟槽。
所述向柱塞2施压的弹簧侧面为连续面，这里的弹簧可以为金属波纹管8(图7、8)、金属环状涨管9(图9、10)、弹簧箍10(图11-13)、网状环胀管11(图14-16)或者为螺旋弹簧环12(图17-18)。这样，由于金属波纹管8(图7、8)、金属环状涨管9的管壁很薄，其弹性密封原理与波纹管相同。螺旋弹簧环12和网状环胀管11的钢丝较细，能够变动螺旋直径或胀管直径，基本上形成连续面。
本发明的实施例不是穷举，仅是示意性的，将所述技术特征的部件，为了减小柱塞与密封件的摩擦进行其它方式组合，也属于本发明的实施例。
