我厂生产的6T/H链条炉炉排链片(见图1),材料为16Mn,料厚14mm。原工艺,仿形气割内圆与齿形→加工内圆与销孔→组装。由于该另件批量较大,技术要求较高,气割后工件质量往往达不到图纸技术要求,造成废品率较高。 82年设计制造了一副链片冲模,将工艺改为:仿形气割内、外圆尺寸φ450/φ230→加工内孔φ240_(+0.10)~(+0.185)
I produced 6T / H chain furnace grate chain pieces (see Figure 1), the material is 16Mn, material thickness 14mm. The original process, copying gas cutting within the circle and the tooth → processing inner circle and pin hole → assembly. Due to the large volume of the other parts, high technical requirements, gas cutting quality of the workpiece often fail to meet the technical requirements of the drawings, resulting in a higher rejection rate. 82 years to design and manufacture of a chain piece die, the process will be changed: profile gas cutting, the outer diameter φ450 / φ230 → processing bore φ240 _ (+0.10) ~ (+0.185)
