Inner spinning feeding device for bottom plate of opposite-wheel driving power spinning equipment

Abstract

The invention belongs to the technical field of spinning, and relates to an inner spinning feeding device for a bottom plate of opposite-wheel driving power spinning equipment. The inner spinning feeding device comprises an inner spinning roller vertical column, an inner spinning roller top plate, an inner spinning roller upper plate, an inner spinning roller lower plate, a cam, a cam mounting barrel, an inner spinning roller, inner spinning roller shafts, a feed screw, a servo motor and a bottom plate, wherein the inner spinning roller vertical column is perpendicular to the bottom plate, andthe middle section of the inner spinning roller vertical column is connected with the inner spinning roller upper plate and the inner spinning roller lower plate correspondingly through guide sleeves; a plurality of inner spinning roller shafts are arranged between the inner spinning roller upper plate and the inner spinning roller lower plate, the inner spinning roller shafts can slide in U-shaped grooves of the inner spinning roller upper plate and the inner spinning roller lower plate so as to realize radial feeding, the inner spinning roller lower plate is connected with the feeding screwthrough a screw nut, and the servo motor drives the feeding screw rod so as to realize axial feeding. According to the device, a brake motor is used as a power source and is driven by the worm and gear, and the inner spinning roller is driven by the cam to be fed along the radial direction of a workpiece, so that an inner spinning roller mechanism is small in size, large in adjusting range and high in positioning precision.

Description

technical field [0001] The invention belongs to the technical field of spinning processing, and in particular relates to an inner-rotating feeding device for the bottom plate of an active powerful spinning equipment for counter wheels. Background technique [0002] The counter-wheel powerful spinning is developed on the basis of the mandrel spinning, and the inner spinning wheel is used instead of the mandrel to process the inner and outer surfaces of the billet at the same time. [0003] The wheel spinning uses one or several pairs of inner and outer rotating wheels to process the inner and outer sides of the workpiece at the same time. Compared with the traditional spinning method, the inner spinning wheel is used to replace the mandrel, which effectively improves the flexibility of the process, saves the cost of spinning molds, improves the inner surface quality of spinning parts, and overcomes the traditional spinning The disadvantage of different deformation of the inn...
