摘要： An improved multiple roller spinning machine for spinning vehicle one-piece wheels is disclosed in which the roller holder is capable of sliding in a direction parallel with the axis of spinning and has a hydraulic cylinder which moves through its axially movable piston rod the holder horizontally thereby bringing the multiple rollers sequentially in to an operating position just above the wheel material clamped between the dies of the driving and driven spindles. Each of the multiple rollers is coupled to a control hydraulic cylinder which drives through its piston the respective roller vertically between a retracted position and a drawing position where the roller is pressed against the periphery of the wheel material. Thus, not only can the sequence of different drawing steps, in a most preferable embodiment, from rough to finishing drawing, be completed in an automatic continued manner, but also operation of the hydraulic cylinder to shift the holder, with the particular roller pressed against the material periphery being set in spinning, causes the roller to draw a wider range than its size across the U-cross section portion of the periphery. According to another embodiment, the holder carries therein multiple rows of different forming rollers arranged radially about a common center such that the wheel material can be subject to drawing by multiple rollers simultaneously applied at different points about the material periphery.

摘要： A delivery device for delivering articles to be heated within a compound furnace, including at least two furnace chambers differing in heating conditions and which can effectively prevent damage to the articles by melt adhesion due to contact with each other and which can also reduce the adverse influence of high temperatures upon the component members of the delivery device is disclosed as including clamps which are capable of reciprocating within a delivery passage and which have the function of clamping and unclamping the articles to be heated so as to deliver or transport the same. Running rods, upon which the clamps are fixed, are adapted to move along the delivery passage and a main drive source for driving the rods and clamps, as well as a subsidiary drive source for performing the clamping and unclamping operations of the clamps are also provided. A movement converting transmission mechanism for converting the linear driving force of the subsidiary drive source into a rotary drive force for rotating the running rods in order to actuate the clamps for performance of the clamping and unclamping operations is included and a clamp positioning mechanism for determining the stopping position of the clamps is operatively associated with the running rods. The movement converting transmission mechanism may include a rack-and-pinion mechanism, a slide bar or rod-crank mechanism, an actuator-gear mechanism, or a cylindrical cam mechanism.
