cored molds per hour and has been able to leverage the mold density achieved using the DISA blow and squeeze mechanism to increase pouring speeds by up to 40%. Pattern changes typically take less than three minutes. Benton’s new DISA Match molding line has benefited the metalcaster’s maintenance, as well. Te machine is the first of its kind with remote diagnostic access, which gives Benton the opportunity for fast online access assistance. Additionally, the simplified, rigid design and elimination of pins and bushings between the cope and drag makes main- tenance access easier, according to Gerry Lewis, Benton’s maintenance manager. “Other maintenance-saving aspects are the automatic oil


lubrication system and in-chamber spray from the side that extends pattern life by preventing sand from sticking to the plates,” Lewis said. With the additional molding capacity from the automatic


line, Benton has been able to expand its market by offer- ing larger castings with greater volumes. Te largest casting produced on the line is a gearbox with a poured weight of

实现了每小时生产103件不包括砂芯的砂型,通过使用 DISA吹气和震压设备来调整砂型的密度,把浇注速度提 高了40%。更换模板只需要不到3分钟就可以完成。 Benton公司的新DISA Match造型生产线对铸造工人 也是很有好处的。这种机器是第一台可以远程诊断的机 器,而Benton公司可以为工人提供在线指导。除此之 外,据Benton的设备维护部经理Gerry Lewis称,这种 简洁、高刚度舍弃了上箱和下箱定位销和轴套的设计还 让维护更方便。 Lewis表示:“其它的设备维护方面包括自动润滑系 统和造型室内侧面吹气系统,这些系统防止了砂子粘到 模板上,从而增加了设备的寿命。” 随着自动化生产线造型能力的提升,Benton已经可 以生产更大的铸件。最大的铸件是一个齿轮箱,浇注钢

Bradken Foundry Improves Employee Retention With Grinding System Te Bradken foundry in Kilburn, Western Australia,


Bradken铸造公司采用新的磨削系统稳定了员工队伍


had 14 injuries attributed to grinding over a 24-month period, four of which resulted in employees being placed on restricted duties. Te employees were using heavy handheld grinders, and the department had low employee retention and high absenteeism. To ease the stress on its workers, Bradken switched to


zeroG grinding systems from Equipois Inc., Los An- geles, Calif., U.S.A. The patented system uses dynamic lift assist to let the operator maneuver the grinder as if weightless while having complete freedom of motion. The system provides 100% mechanical lift and motion without the use of an electrical, pneumatic or hydraulic power source. ZeroG’s cables and hoses are located along the length


of the arm to prevent damage and reduce tripping hazards. Because tools are no longer dropped when not in use, tool repair costs are reduced. Tools are held in optimum grinding position and pressure, so grinding disc usage can be reduced by 30-40%. Bradken reports zeroG reduced the total hours required


of 2.72-16.33 kg. ■ Visit www.equipoisinc.com for more information.


for grinding-related tasks by more than 60%. Absenteeism in the grinding area was reduced by nearly 50%. Te metal- casting facility’s $36,000 investment was paid back in a little over two months. ZeroG grinding arms can be mounted in fixed or por- table locations. Its Double Link Arm is suitable for payloads


Bradken铸造公司(Kilburn,西澳大利亚)在过去 24个月内发生了14起有关磨削的生产事故。其中四起 是由于员工的职责受到了限制。员工们使用重型的手持 砂轮机进行工作。事故导致了相关部门的员工的流失。 为了减轻员工的压力和负担,Bradken从Equipois公 司(洛杉矶,加州,美国)引进了零重力的磨削设备。 这项受专利保护的系统采用动态提升装置,来辅助操作 者在没有重力、完全可以自由运动的情况下完成磨削。 系统提供了全部的机械提升和运动,而不需要额外的电 动、气动或者水力的动力源。


零重力设备的电缆和软管随着臂的长度而固定,这样 防止造成伤害,同时减小了脱扣的风险。因为工具即使 在不使用的时候也不会处于悬挂状态,因此工具的维修 成本也降低了。这种设备优化了磨削的位置和压力,这 样砂轮片的用量也减小了30-40%。 Bradken报告显示零重力设备使得磨削工作时间减小 了60%。磨削部门的缺勤率降低了50%。而铸造厂为此 花费的3.6万美元的投资在短短2个月内就得到了回报。 零重力的磨削臂可以装配在固定或者移动的工位。它
