The invention discloses a 3D printing machine which comprises a printing chamber. A printing assembly and a bearing platform are arranged in the printing chamber. The printing assembly is arranged above the bearing platform. The printing assembly comprises a printing support, a printing head assembly and a curing lamp assembly, wherein the printing head assembly and the curing lamp assembly are connected to the printing support. The printing support moves in the printing direction. In the printing direction, the printing head assembly is located in front of the curing lamp assembly. The printing head assembly comprises a main printing head body of a printing model body and an auxiliary printing head body of a printing supporting material. The model main material is photosensitive resin. The printing temperature in the printing chamber is lower than the solidification temperature of the supporting material. The supporting material is solidified at the printing temperature. The invention further discloses a 3D printing method. By means of the 3D printing machine and the 3D printing method, the supporting material is removed easily.

The invention discloses a mandrel supporting device for a cylindrical workpiece. The mandrel supporting device comprises a mandrel, a split lining body and a plurality of length adjusting rods, wherein the split lining body is clamped on the mandrel, and the plurality of length adjusting rods are uniformly distributed in the circumferential direction of the outer edge of the split lining body; andthe length adjusting rods comprise tubular parts, shaft sleeves, transition joints, supporting rods, ejector rods and top block assemblies, wherein the tubular parts are fixedly connected with the split lining body, the shaft sleeves are arranged in the tubular parts, threads are arranged at the two ends of each transition joint, one ends of the transition joints are in threaded connection with the shaft sleeves, the other ends of the transition joints are in threaded connection with one ends of the supporting rods, the shaft sleeves and the supporting rods are opposite to the rotating direction of threaded holes which are connected with the transition joints, the other ends of the supporting rods are in threaded connection with one ends of the ejector rods, the other ends of the ejectorrods are connected with the top block assemblies, and the top block assemblies are used for abutting against the inner wall of the cylindrical workpiece to be machined. The mandrel supporting device for the cylindrical workpiece is suitable for large-size cylindrical workpieces, and adaptability of the mandrel supporting device is improved.

The invention discloses a method and system for laser cutting through dynamic following of synchronous passing plates. The system comprises one or more machining positions, a synchronous passing plate unit, a laser cutting unit, a carrying stacking unit, a waste conveyor belt device, a smoke treatment device, a real-time measuring device for strip steel cutting, a position detection device and a cutting control system, wherein magnetic belt sets are adopted in the synchronous passing plate unit and arranged on the feeding side and the discharging side of each machining position respectively, magnetic belts can stretch and retract, and the belt intervals are adjustable; the laser cutting unit is arranged at each machining position and comprises at least one laser cutting machine and a laser cutting head; the carrying stacking unit comprises a stacking table and a stacking robot, and the stacking table is arranged on the outer side of the magnetic belt set on the discharging side of each machining position; the waste conveyor belt device is arranged on the side, perpendicular to the feeding direction, of each machining position; the smoke treatment device and the real-time measuring device for strip steel cutting are arranged at each machining position; the position detection device in front of sheet stacks is arranged at the carrying position of the magnetic belt set on the discharging side; and the cutting control system controls all the units, and the magnetic belts stretch or retract to follow the laser cutting head. Dynamic following of the magnetic belt sets can be achieved in the cutting process, so that the machining tact time is shortened, and the yield is further improved.
