模座是模锻锤上的重要零件之一。模座的质量好坏,直接影响着锻件质量。模座属于易损件,常在燕尾槽底面及两侧面出现打塌、凹坑等破坏现象,严重影响着锻件质量。过去,我们采用拆下模座,送到热处理车间进行预热,然后用电焊条堆焊,再送到机修车间进行冷加工的修复工艺。这种工艺修复周期长(需7天时间),成本高,拆除模座困难且劳动强度大,故现在我们采用了在模锻锤上直接对模座进行堆焊、打磨的修复工艺,大大缩短了修复时间(需2天),修复成本大为降低,且
Die base die forging hammer is one of the important parts. Die quality is good or bad, a direct impact on the quality of forgings. Mold base is wearing parts, often dovetail groove and the two sides of the collapse, pits and other damage, a serious impact on the quality of forgings. In the past, we used to remove the mold base, sent to the heat treatment plant for preheating, and then welding with electrode surfacing, and then sent to the mechanic shop for cold repair process. This process has a long repair cycle (7 days), high cost, difficult to remove the mold base and labor-intensive, so now we used in the die forging hammer directly on the mold base welding, grinding repair process, greatly shortening The repair time (2 days), the repair cost greatly reduced, and
