Embodiment Construction

[0014] The present invention as Figure 1-3 As shown, it includes a body composed of a base 1, uprights 6 on both sides and an upper beam. On the table of the base 1, there is a spinning die 3 for placing the workpiece 2, and the lower part of the upper beam corresponds to the workpiece 2 on the spinning die 3. A pressing plate mechanism is provided, and a spinning head device is provided on the inner side of the column 6. The spinning head device includes a spinning head 4, a spinning head seat 7 and a spinning head seat driving device, and the spinning head seat 7 passes through the X direction. , the Z guide rail is movably connected with the column, and the spinning head 4 is movably connected with the spinning head seat 7 through the hinge shaft 8 and the hydraulic cylinder 5, so that the spinning head 4 can move in the X and Z directions relative to the spinning head seat 7 A small amount of rotation is realized around the hinge shaft 8 in the plane formed by the axis. ...

Abstract

The invention discloses a spoke spinning machine and relates to a spinning machine for processing plates into shapes of bowls and dishes through cold extruding. The spinning machine comprises a machine body consisting of a base, upright posts on two sides and an upper transverse beam; a spinning mold for accommodating a processed workpiece is arranged on the base surface; a pressing plate mechanism is arranged on the lower part of the upper transverse beam corresponding to the processed workpiece on the spinning mold; and a spinning head device is arranged on the inner sides of the upright posts. The spinning head device comprises a spinning head, a spinning head base and a spinning head base driving device, wherein the spinning head base is movably connected with the upright posts through an X-direction guide rail and a Z-direction guide rail; and the spinning head is movably connected with a hydraulic cylinder through a hinged shaft, so that the spinning head can slightly rotate in a plane formed by an X-direction axis and a Z-direction axis around the hinged shaft relative to the spinning head base. The spoke spinning machine guarantees that a friction surface on the upper part of the most protruding point of the spinning head can be reliably contacted with the workpiece.

Description

technical field [0001] The invention relates to a spinning machine for processing sheet material into a dish shape through cold extrusion, in particular to the improvement of the spinning head device of the spinning machine. Background technique [0002] The CNC closed-loop spoke spinning machine is mainly used for spinning and forming automobile spokes. Spinning-formed spokes have the advantages of unequal thickness, equal strength, and beautiful appearance; they can be widely applied to the different requirements for spokes of inner tube and tubeless rims. Spoke spinning is a kind of composite spinning, which has both the characteristics of ordinary spinning and the characteristics of strong extrusion and thinning for flat plates (special steel plates for automobile spokes). [0003] Spinning processing belongs to cold extrusion forming. The spinning head exerts a great extrusion force on the workpiece, so that the circular flat plate is deformed into a dish or wheel spok...
