India turn the issue of slotting cutter life

Treatment. More flexible method (= J preferred materials, and high hardness, good bad Toru Tan opened the fish knife. Indeed HRc6o hardness and wear resistance over, but the drawback is poor hardenability deformation too, easy to crack, no optimization; alloy hardness of actinium 9CrSi heat up ERC60-63, abrasion resistance and toughness are better; high-speed steel W18CO.V heat treatment up to HRC66, with high wear resistance and a certain toughness. selected 9CrSi, W18Ci4V appropriate 2, to prevent abnormal edge cracks. steel after forging to achieve the desired tool shape, but the internal organization to become closer,[link widoczny dla zalogowanych], quality improvement phase, but requires the forging process to avoid forging cracks. take full account of the process of heat treatment to avoid quenching cracks and other defects. 3 in strict accordance with plans to install new inspection tool. carton packaging business outsourcing outsourcing generally acquired through a new slotted knife, need to focus on is this: will decadent dimensional tolerances specified in accordance with the drawings, materials, hardness demanding acceptance. Fourth, exploration of the old knife factory and then grinding to improve the printing machine and printing slotting machine clog 4 mold in the slot machines and other machine tool life, tool slot on the day were repeated 』grinding and then to explore. put into use over the past year, with good results. examples are as follows: (a】 ~ '-ItJ Tan air. file Xie Tian fact file on the device the original semi-circular ring width, thickness 7.16ram, blade thickness on the new 7mm,[link widoczny dla zalogowanych], double the gap between the upper and lower mouth edge △ z = 0.I6mm, single-sided gap △ Z / 2 = 008】 ring radical new system file to set three kinds of width and thickness were set at 686ram, 656mm,[link widoczny dla zalogowanych], 6.26turn. adjacent to two kinds of thickness difference 2X = 0.3mm. in diameter with the original circle the same width as files, materials, Shop No. 45,[link widoczny dla zalogowanych], heat treatment HRC35-40, both ends of the surface grinding. (=) tool with real shabu points fecal measurement tool ● Dan cut a class. the old tools (including the old slot knife, the old Notching trimming knife, etc.) sub-classification of registered aircraft measurements and kind words on the well marked, classified storage. proud arrive physical line cards to be delivered by grinding or Dayton. 2. grinding. To enable the tool to maintain normal working with. tool grinding must be delivered when the grinding Ha Shu awarded at the drawings to indicate the dimensional tolerances and technical requirements, the treasury each time after grinding to rigorous testing and acceptance,[link widoczny dla zalogowanych], Whenever on the timely return does not meet the re-grinding, until the slot on passing 』at knife grinding, and sought assurances from top to bottom edge and the mouth of the gap between the operator sets a reasonable quality and other factors slotted cartons, set the allowable value x: 015mm, then 2X: 03mttl where the knife part of the overall thickness of a blade thickness of <015mm grinding face b, to wear until the polished surface; where the thickness of an edge on the knife part of the overall thickness of ≥ D15ram to 030ram overall thickness of a surface grinding, surface grinding to wear light and thickness of 67ram, 64ram, 6.1mm an adjacent three of the most far; also available on the b side and the overall thickness of the same grinding. the old slot under the knife, cutting angle grinding knife cutting edge, where d No case of surface defects, all grinding c surface to wear until the polished surface. 【j) 1 日 ● knife blade and then a loading space to ensure that a reasonable upper and lower knife and ring width file, you must sit in the right lead use, supporting the combination, double-check the gap between the upper and lower edge port is normal. requires a reasonable gap of 012 difficult surface to 018ram, 006 single reasonable gap to 0.09ram, if the gap does not match must be re-equipped with knives, should not mix and match, requiring matching dimensions conform to the following table: the upper and lower knife 【slotted wheel) and the supporting ring width file size atlas on the thickness of a knife ring width profile thickness 7 ± 001 (New Tool) I716 (New) 6.7 ± 0.01 ( old knives.) 686 (67) 64 ± 001 (old cutter) l656 (6.4) 6.1 ± 001 (1 day) 『6.26 (61) 2 installed to focus on the same corner cutting edge cutting blade gap adjustment, requiring single gap 006 to 009mm. Notching tool to install in place, and the gap between the knife cutting edges <05ram. Whenever the error is large gap pad and other measures to be taken to adjust the folder, until it meets the requirement. Practice has proved that by exploring and improving, so that the more scientific and rational reuse Brothers, slotted knife blade extends the service life of more than twice, and to ensure a better use of effects, both to improve the quality slotted carton , but also too big to save the tool consumption costs resulting from the China Packaging ● l9 1999 No. 6 105
