具体实施方式
下面结合附图和具体实施方式对本发明作进一步的描述。
如图 1所示, 本发明所述的圆管下料坡口机包括下料部分、进料 输送机和定位卸料机三个功能部件。这三个功能部件之间可以采用分 体式结构, 也可以采用轨道 20将三部分连接起来, 这样可以便于根 据管道的长度调整三个功能部件之间的距离。
下料部分起到切割和坡口的作用, 如图 2、 图 3所示, 下料部分 包括下料机架 1、 通过轴承安装平行安装在下料机架 1上的一对下料 滚轴 2, 下料滚轴 2与驱动电机 9传动连接; 下料机架 1为矩形框架 结构, 在下料机架 1上表面的前后两端分别固定安装两组轴承座, 每 组轴承座中安装一根下料滚轴 2, 两根下料滚轴 2均通过皮带和皮带 轮与驱动电机 9传动连接, 这样, 驱动电机 9可以带动两根下料滚轴 2同步、 同向旋转。 另外, 在下料机架 1的前端通过支架 3安装有等 离子切割机 4。 如图 7所示, 所述支架 3为固定连接在下料机架 1上 的三角架, 在支架 3的顶端铰接一个垂直于下料滚轴 2的支架杆 31, 支架杆 31与支架 3之间还设置有弹簧 32, 等离子切割机 4采用螺栓 连接或者绑带绑定的方式固定在支架杆上。在支架 3的末端通过轴承 安装有滚轮 33。 切割圆管的时候, 滚轮 33压在圆管上, 适当调整好 等离子切割机 4的角度,在等离子切割机 4切割的同时,使圆管旋转, 即可将圆管切断, 并在断面处产生一定角度的坡口。在下料机架 1的 前端还安装有举升装置,所述举升装置包括通过铰轴安装在下料机架 1上的举升框架 5, 所述铰轴位于举升框架 5的中部, 举升框架 5的 一端通过轴承安装有下料举升辊 6, 举升框架 5的另一端安装有下料 液压油缸 7, 下料液压油缸 7的一端连接在举升框架 5上, 另一端连 接在下料机架 1上。当下料液压油缸 7工作的时候可以带动举升框架 5上下摆动, 从而使下料举升辊 6升高或降低。
进料输送机的作用是为了方便将待加工的圆管向前输送。进料输 送机设置在下料机架 1的后端。如图 4所示, 所述进料输送机包括进 料机架 8、通过轴承安装平行安装在进料机架 8上的一对进料滚轴 81, 进料滚轴 81与下料滚轴 2顺向设置, 在进料机架 8的一端通过框架 铰轴安装有进料举升框架 82, 所述框架铰轴位于进料举升框架 82的 中部, 进料举升框架 82的一端通过轴承安装有进料举升辊 83, 举升 框架 5的另一端安装有进料液压油缸 84, 进料液压油缸 84的一端连 接在进料举升框架 82上, 另一端连接在进料机架 8上。
定位卸料机有两个作用, 其一是确定切割下来的圆管的长度, 其 二是在等离子切割机切割圆管的时候支撑前端的圆管,并在切割完成 以后将圆管卸下来。
定位卸料机设置在下料机架 1的前端,根据需要的圆管的长度调 整好定位卸料机和下料机架 1之间的距离。如图 5所示, 所述定位卸 料机包括卸料机架 10, 通过轴承平行安装在卸料机架 10上的一对卸 料滚轴 101, 卸料滚轴 101与下料滚轴 2顺向设置。 如图 5、 图 6所 示, 在卸料机架 10上还通过轴承安装有卸料轴 102, 卸料轴 102与 卸料滚轴 101平行设置, 卸料轴 102上固定安装有卸料爪, 卸料爪与 卸料机架 10之间设置有卸料液压油缸 103,所述卸料爪包括主杆 104 以及与主杆 104垂直并分别固定连接在主杆 104两侧的连杆 105、 挡 杆 106, 所述连杆 105固定连接在卸料轴 102上, 主杆 104上设置有 铰轴座 107, 并通过该铰轴座 107铰接在卸料液压油缸 103的顶端; 这种卸料爪至少在卸料轴 102的两端各设置一个。与卸料爪配合使用 的卸料液压油缸的数量也可以根据需要设置。
在卸料机架 10的前端通过轴承安装有定位轴 108, 定位轴 108 与卸料滚轴 101平行设置,并且在定位轴 108上朝向卸料滚轴 101的 一端固定安装有定位盘 109。
使用时, 将待加工的圆管放到两下料滚轴 2 上, 由于进料滚轴 81和卸料滚轴 101均与下料滚轴 2顺向, 所以待加工的圆管其实也 是放在了进料滚轴 81和卸料滚轴 101上。 调整好定位卸料机与下料 机架 1的位置, 使圆管的前端顶在定位盘 109上。开动驱动电机 9带 动两根下料滚轴 2同步、 同向旋转, 从而带动圆管旋转, 此时开启等 离子切割机 4即可将圆管切断, 并在断口处产生一定角度的坡口。此 时, 位于定位卸料机上的圆管是已经切割完成的成品, 操纵卸料液压 油缸 103, 卸料液压油缸 103推动主杆 104升高, 主杆 104又通过连 杆 105带动卸料轴 102旋转,从而带动连接在卸料轴 102上的其他卸 料爪同步工作, 将切割完成的圆管举起, 最终顺着主杆 104滑落到地 面。 挡杆 106的作用是防止圆管滑向另一侧。
切割完成以后,位于下料部分和进料输送机上的仍然是待加工圆 管, 此时同时开启液下料压油缸 7和进料液压油缸 84, 通过杠杆的 作用, 分别使下料举升辊 6和进料举升辊 83升高。 下料举升辊 6和 进料举升辊 83升高的时候将待加工圆管抬高, 离开下料滚轴 2和卸 料滚轴 101, 此时操作工人可以很容易地推动待加工圆管向前移动, 直到其前端顶在定位盘 109上, 操纵下料压油缸 7和进料液压油缸 84复位, 待加工圆管下降放到卸料滚轴 101上, 等待进行下一工作 循环。
