Characteristics of the roller shaft produced by the production line. Main technical performance: 1> Processing range: Φ20-Φ40MM, length 280-2400, total power: 58KW, hydraulic system pressure: 6.3Mpa, pneumatic system pressure: 0.6-0.8 Mpa, electrical control system consists of touch screen, PLC, servo, inverter, etc. Figure 4 TSZX-1 type roller shaft CNC automation production line. 2> SGZX-Ⅰ roller shaft milling and cutting CNC machine: saw blade diameter 250-285, 5.5KW variable speed, servo motor CNC fixed-length feeding, feeding length 0-2500, length error ±0.05, hydraulic clamping, pneumatic flipping and sorting. 3> SGB-Ⅰ roller shaft milling flat and groove special machine: dual groove milling function driven by 4 sets of 3KW motors, both ends of the roller shaft milled simultaneously to complete dual grooves at once, variable speed feeding; dual flat milling function driven by 2 sets of 5.5KW motors, both ends of the roller shaft milled simultaneously to complete dual flats at once, variable speed feeding, hydraulic clamping. 4> SG-Ⅱ roller shaft end face chamfering and grooving CNC machine: nationally unique with multiple patents, fully CNC dual-head end face, chamfering, and grooving completed automatically at once, hydraulic clamping, variable speed feeding, using CNC turning tools for processing, high precision and durability, easy tool change, length error ±0.05, highly praised by users. 5> SGZP-Ⅰ roller shaft dual-head flat drilling machine: driven by 2 sets of 2.2KW motors, 3-speed variable, with anti-metal chip winding function (patented technology), hydraulic clamping, infinitely variable speed feeding, both ends of the shaft drilled simultaneously and automatically completed at once. 6> Translating mechanical arm total support: this machine completes translation, lifting, and positioning trajectory with 3-coordinate rolling linear guide rails, and then 4 sets of pneumatic mechanical arms complete the functions of grabbing, lifting, translating, and positioning the roller shaft, with multiple national patents. This machine has a simple and reliable structure, high efficiency, low cost, and high cost-performance ratio. Currently, the processing of roller shafts in China is done by 4 independent devices operated by 4 people, with a class output of about 250 pieces, which is inefficient and has low processing accuracy. This combined processing center is operated by 1 person, with a finished shaft production cycle of <50s, class output ≧500 standard pieces, and labor efficiency improved by 8 times compared to ordinary equipment. The TSZX-1 type roller shaft CNC automation production line uses CNC technology, producing finished shafts with a precision of ±0.05. Due to high processing accuracy and high batch consistency, it provides processing equipment for the design and manufacture of high-speed, large-capacity belt conveyors.
