Silk hole protection bolt restructuring method improvement

2019 - orifice protection bolt restructuring method improvement 05 - 12 DE shi zhao zones branch company of an illustrated the product after welding, project description, casting, in order to prevent shot silk hole damage, need to protection of orifice, the M12 silk hole using bolt. For silk hole depth difference between different specifications, so the use of protective bolt should also according to different wire hole depth, and length of different specifications, including protective bolt length 10 mm for not directly purchase, that have been taken to use standard bolt car system to meet the production requirements. Illustrated with casting yield increasing, protective bolt demand increasing, using long bolt system couldn't keep up with production demand, serious loss and tools. Second, improve thinking and innovation to improve the efficiency of this kind of bolt production, production of specialized equipment and tooling, use sawing machine cutting, cutting can produce 6 pieces at a time, meet the length requirements. Three improvements according to the field trial has now started, sawing the bolt meets the requirement, the first batch of 1000 pieces of the transformation, improve the former: car production system of class 100/8 hours, car system each time for 20 seconds; Improved: sawing class production 1000/8 hours, cutting hours 10 seconds per piece. 10 times higher production efficiency, single class saves hours 300 yuan, save time and effort, the efficiency is greatly improved. Sequence will continue to reform after 3000 or so, can satisfy the bolt use requirement.
