The invention belongs to the technical field of winding equipment, and particularly relates to a flexible vibration isolation winding machine and a winding method thereof.The flexible vibration isolation winding machine comprises a winding rack, a fixed disc is fixedly connected to the upper end of the winding rack, a rotating rod is rotationally connected to the fixed disc in a penetrating mode, and the rotating rod is sleeved with a winding roller; a first supporting rod is fixedly connected to the upper end of the winding rack, a first motor used for driving the rotating rod is fixedly connected to the side wall of the first supporting rod, a fixed wheel is arranged at the upper end of the winding rack, and the fixed wheel is sleeved with a take-up roller used in cooperation with the winding roller; and the buffering mechanism comprises a plurality of sliding grooves formed in the fixed disc in a circumferential array mode, and transmission plates are linearly and slidably connected into the sliding grooves. By arranging the buffering mechanism, the rigidity of the gas spring can be continuously reduced along with winding work, so that the vibration isolation performance of the gas spring is improved, and the vibration isolation performance is always matched with the vibration amplitude of the winding roller.

The utility model relates to wire drawing machine pay -off technical field, and disclose a wire drawing machine pay -off device with line pressing structure, including bottom plate, pressure mechanism and abutting mechanism, the upper surface fixed connection of bottom plate has the support plate for supporting pay -off roll, the top of support plate is equipped with the fixed ring for fixed pay -off roll, one side of bottom plate is equipped with support column, the pressure mechanism is established in the top of support column, the pressure mechanism sets up in the circumference of pay -off roll upper, the utility model provides a wire drawing machine pay -off device with line pressing structure, through the cooperation setting of bottom plate, support column and pressure mechanism, can press the steel wire rope on the line roller in the upper, make the movement of steel wire more smooth in the pay -off process, reduce the knot of the steel wire between the occurrence, further cooperation setting abutting mechanism in the bottom, can extrude the steel wire on the line roller from below, make the steel wire more stable when paying -off.

The application discloses a kind of convex structure 3D printing method of inner cone parts, belong to 3D printing manufacturing technical field, it includes box, the base is placed in the bottom of the box, the outer side of the base is fixedly installed with portal frame, the first motor is installed in the base side, the fan that is used with the air suction pipe is installed in the working tank, the filter plate is installed in the first fixed block buckle;Through the extension head structure design to the inner wall of inner cone part main body, extension head itself has the effect of strengthening the overall structure support strength of part, the use amount of extension head and part inner wall part support can be greatly reduced when D printing, not only reduce the support material cost, but also can reduce subsequent support piece removal process, avoid to cause damage to extension head, part inner wall when removing support, further improve part forming quality and production efficiency, especially adapt to the precise printing demand of complex convex structure such as inner cone part inner wall extension head with structural strengthening function.

The utility model relates to the technical field of steel coil packaging protection devices, in particular to a protection device for steel coil packaging, which comprises a horizontal saddle and a steel coil, and is characterized in that a sinking groove is arranged at the upper end of the horizontal saddle, a rubber bottom pad is embedded in the sinking groove, the steel coil is arranged above the rubber bottom pad along the longitudinal direction, a protection layer is wrapped outside the steel coil, and the steel coil is arranged in the sinking groove. Two driving parts which are symmetrically arranged left and right are arranged at the upper end of the horizontal saddle, each group of driving parts is fixedly connected with an ejector rod, each ejector rod is fixedly connected with a baffle, and each baffle is fixedly connected with a rubber side pad which is used for abutting against the outer edge of a steel coil; the protective layer comprises two paper corner protectors which are correspondingly arranged front and back and movably sleeved with the two ends of the steel coil respectively, the surface of the steel coil is coated with gas-phase antirust paper, and the paper corner protectors are made of corrugated paper.
