Description

  The present invention relates to a squeeze roller replacement method for a vertical spinning machine, and more particularly to a squeeze roller replacement method for a vertical spinning machine that can be moved and replaced easily.

  Conventionally, a vertical spinning machine is used in a case where spindles are arranged in parallel, pulley work is sequentially supplied to each spindle by a transport mechanism, and a plurality of processes are automatically performed (for example, Patent Documents 1 and 2).

  The vertical spinning machine has the advantage that the installation area it occupies can be reduced as compared with the horizontal spinning machine. Therefore, in addition to the above case, the vertical spinning machine is used when the installation area is limited.

When a conventional vertical spinning machine is applied to a wheel work in which an aluminum casting material is drawn and formed into a wheel, for example, as shown in FIG. 4, an electric motor (not shown) is mounted on a frame 8 of the vertical spinning machine. The main shaft 1 that rotates around the vertical axis is disposed, and the mandrel M corresponding to the workpiece W to be processed is disposed on the main shaft 1.
A tailstock device 2 for pressing and fixing the work W attached to the mandrel M from above is disposed above the main shaft 1. The tailstock device 2 is provided with a pressing member 3 that abuts against the workpiece W and urges the mandrel M, and a pressing means 9 such as a hydraulic cylinder that moves the pressing member 3 up and down. The pressing member 3 is rotatably attached to the tip of the rod of the pressurizing means 9 via a bearing portion 4 having a bearing so that the pressing member 3 can rotate together with the workpiece W.
Although the tool base 10 is disposed on the gantry 8, the number thereof is not particularly limited, and a plurality of tool bases 10 can be disposed according to the processing content of the workpiece W.
The tool table 10 is provided with a diaphragm table 11 to which a diaphragm roller R for forming the workpiece W into a desired shape by being pressed against the workpiece W is mounted so as to be able to move in the X-axis direction and the Z-axis direction.

In this vertical spinning machine, a workpiece W placed on a mandrel M is pressed and fixed from above by a pressing member 3 of a tailstock device 2 and rotated along with a main shaft 1.
Next, the workpiece W is subjected to spinning processing following the mandrel M by moving in the X-axis direction and the Z-axis direction with the squeezing roller R pressed against the workpiece W.
Thereafter, the pressing member 3 of the tailstock device 2 is moved upward, the workpiece W is extracted from the mandrel M by an appropriate means, and the processing is completed.

By the way, in such a vertical spinning machine, when exchanging the squeezing roller R, the upper frame 5 of the spinning machine is above the squeezing roller mounting position, so it is difficult to use a crane of factory equipment, In a vertical spinning machine used for a wheel work, since the weight of the squeezing roller R is as large as about 250 kg, there is a problem that it is difficult to attach and remove the squeezing roller R, and it takes time to replace it.
