今年,我厂修复了一台400公斤空气钟。在检修过程中,发现该空气锤的前缸缸径磨损很严重,椭圆度0.1毫米,锥度也达0.15毫米,且在缸壁上划有两条深约0.5毫米、宽约40～50毫米、长约700毫米的深痕,从而失去了该设备原有的精度。该设备是较高大而笨重的,其外形尺寸为2000×1000×2500毫米。由于我厂设备不足,要对它进行修复是颇为困难的。但我们在群众的努力下,终于解决了问题。我们利用机修车间现有的Z35型摇臂钻床作为动力来源,在该锻锤的床身上进行加工,即将原来的缸径
This year, our factory repaired a 400 kg air bell. During the overhaul, it was found that the front cylinder bore of the air hammer wears badly with an ovality of 0.1 mm and a taper of 0.15 mm, with two deep grooves of about 0.5 mm and a width of about 40 to 50 mm on the cylinder wall About 700 mm deep marks, thus losing the original accuracy of the device. The device is tall and cumbersome, its dimensions are 2000 × 1000 × 2500 mm. Due to the lack of equipment in our factory, it is quite difficult to repair it. However, with the hard work of the masses, we finally solved the problem. We use the machine shop existing Z35-type radial drilling machine as a source of power in the forging hammer bed body, that is, the original bore
