我厂B505CK插床的滑枕拉伤后,经采用热喷焊修补,效果很好。 1.B5050K插床滑枕的损坏情况 B5050K插床滑枕拉伤长600mm,宽8～10mm,深0.8mm,呈条状(见图1)。其中l_1部分出现明显的拉伤痕迹,l_2部分只是细微伤痕,拉伤深度为0.10～0.30mm,呈间断线状。 由于l_2区只有细微、间断的伤痕,程度较轻,我们只采用刮研方法修光毛刺,修光面稍低于滑枕表面,在充分润滑条件下不会影响使用。本文着重谈一下关于l_1区的热喷焊修补问题。 2.插床滑枕拉伤的修复 I plant B505CK Slit ram bed, after the use of thermal spray repair, the effect is very good. 1.B5050K ram bed ram damage B5050K slot ram racking length 600mm, width 8 ~ 10mm, depth 0.8mm, was strip (see Figure 1). Where l_1 part of the obvious signs of trauma, l_2 part is only minor injuries, the depth of injury 0.10 ~ 0.30mm, was discontinuous linear. As l_2 area only subtle, intermittent scars, to a lesser extent, we only use scraping method to repair burr, polishing surface slightly lower than the ram surface, under the conditions of adequate lubrication will not affect the use. This article focuses on about l_1 area thermal spray welding repair problems. 2. Sliding bed ramps repair
