Jining [] / [Jiaozhou] / [] Roller Tyan manufacturers preferred Jiuchuan rubber Jiuchuan rubber roller manufacture quality standards and procedures are as follows: a. Purchase of raw materials production process - acceptance of storage - pipe, the lower shaft material (tubing cut to ensure vertical degrees) - tube axis machining - tube, bearing butt - shaft bearing press-fit - plus Lubricants - loaded seal retainer - rotation test (to ensure that the rotation rate of 100%) - Clean welding slag, welding tumor, dust, etc. - painting - Packaging II. Quality and technical requirements: 1. roller tube, roller shaft (drawing bar), press bearing and supporting seals should be tested, oval tube diameter tolerances ≤0.6mm, cold drawn bar diameter tolerance of + 0.002 + 0.012mm, bearing and supporting the seal assembly first trial, there must be steel shaft retainer, installed after constantly, without distortion. Other spare parts should be used only after the inspection. Because large quantities of spare parts, test for the sampling, production, assembly problems found, the workshop shall promptly notify the quality control personnel, quality control section is responsible for organizational analysis, process. 2. Cutting: roller tube and shaft cutting, the cut surface of the tube and the axis perpendicular to the axis. Tube and shaft length tolerance ≤2mm, vertical tolerance ≤2mm. 3. tube: In a double-headed lathe at both ends of the bearing tube steps, processing diameter and depth of dimensional tolerances must comply with the requirements of the drawings you want to make sure that the assembly requires two bearing retainer of concentricity and ends. 4-axis machining: The machine axis ends to be flat, according to drawings retainer groove depth, depth tolerances in accordance with drawings; two retainer groove spacing and size to be maintained after the pipe assembly and the flat pad gap ≤1mm. Axis machining flat mouth, ends flat mouth size and spacing tolerances shall comply with requirements of the drawings. 5. butt: When the double-headed automatic welding machine bearing, welded pipes, tools should be moderately tight top and must ensure concentricity not skewed, no shaking; circumferential welds should be uniform, smooth, firm, weld must not drop below the height of 3mm, non Weld, partial welding, weld, or should be welding job, it must make the necessary grinding after welding, cleaning, roller surface welding tumor presence is strictly prohibited. When welding different roller diameter, rotation speed, the welding wire feed speed, wire diameter, welding current and voltage should be regulated to ensure that the weld strength and size to meet the requirements. 6. mounted bearings: hydraulic automatic when installed on the tops bearing shaft and bearing, seals leak must ensure that equipment, bearings properly lubricated and put positive. Pair Location: The dress should be accurate positioning, bearing that is pressed into place to another non overvoltage; regular checks of installed capacity slide and tooling center are the same, to ensure that the rear axle of the equipment and pipes, bearing concentric, flexible shaft. 7. Seal and retainer: before and after the oil chamber should fill the special lubricating oil, lubricating oil should be applied to two-thirds of the space within the seal groove and bearings. When loading the seal and retainer, iron seal and bearing should closely aligns with the seal retainer pad clearance should be within 1mm, more than 1mm gap must repair. Retainer should complete card in the slot. Assembly, due to damage to the seal assembly must be replaced, drain attachments is strictly prohibited. 8. After assembly is completed, roller rotation flexibility to ensure that, can not have jamming, turn no phenomenon. After completion of the rollers, the requirements of each operator should be controlled trials of rotation is not flexible to be reworked. 9. In addition to quality control personnel inspection process, but also to deal with the finished product sampling, the problems identified instruct the responsible unit resolved. 10. rollers finished to classified storage, neatly prohibited bump. 11. shipments, responsible units should be checked quality storage case idlers do not meet the above requirements must be handled, until qualified. 12. rollers respond before painting roller surface treatment, painting should be uniform seamless spray, roller surface should be cleaned after painting, to prevent sticking a foreign body, affecting the product image.
