これがため焼入時彎曲し、研摩加工の取り代が大
となり研摩工数も多く要し、加工費が嵩み高価と
なる等の欠点がある。 Conventional methods for forming spindle blades include cutting a round bar into a desired shape. However, such cutting requires a large number of cutting man-hours and wastes material, and since the shape is elongated, it cannot withstand heavy cutting, therefore cutting takes time, and when the cutting speed is increased, the surface condition is poor. Cutting resistance causes internal distortion,
As a result, it becomes curved during quenching, requires a large amount of material to be removed during polishing, requires a large number of polishing steps, and has drawbacks such as increased processing costs and high prices.

にしたものである。 This gripping device H rotates in the rotational direction of the swaging machine at a rotation speed slower than that, and grips the material gently, in other words, allows the material to follow rotation due to the swaging process to a certain extent. The rotary cylinder 87 is equipped with a sprocket wheel 86 that is interlocked with an appropriate drive source M (Fig. 3), and a bearing 89 is installed in the case 88. A fastening fluid cylinder 81 is attached to the proximal end, and the top cover 83 is attached to the distal end. The inner hole at the tip of the rotating cylinder is made into an inclined surface that fits the tip of the collector chuck 82, and the chuck is fitted and supported.The operating rod 90, which is connected to the rod of the cylinder 81, is connected to the rotating cylinder 87 by a key 91. , a connecting tube 9 screwed into the rear end of the chuck 82;
2 are engaged with each other by a ring 93, and as the operating rod 90 moves back and forth, the connecting cylinder 92 moves forward and backward together, but the connecting cylinder is held so as to freely rotate. This is because, as will be described later, normally the collet chuck 82 and the connecting tube 92 are rotated together with the rotary tube 87, but when the material is rotated at a speed higher than the rotational speed of the rotary tube 87 during swaging processing, the collet chuck 82 and the connecting tube 87 are rotated. The tube 92 is designed to follow this to some extent.

It is designed to apply pressing force to the FIG. 9 shows another example of the rod 94, in which the rod 94a is attached to the lower step bearing portion 24 of the material.
It is provided with the same taper hole 94b as the one shown in FIG. 96 in Figure 7
is a fluid cylinder for advancing and retracting the gripping device H relative to the swaging machine.

る。 According to the invention, each gripping device H is rotated in the direction of rotation of the swaging machine and at a slower speed, and the collection chuck is rotated in the direction of rotation of the swaging machine and at a slower speed, and the collection chuck is rotated in the direction of rotation of the swaging machine. Since the material is gripped to allow slipping, the material will not be twisted due to the rotation of the swaging machine, and the gripping surface will not cause defects due to slipping while being gripped. This is done automatically and continuously, which is extremely efficient, and because the lower bearing support part, which has a small diameter with a step, requires two processes: rough striking and finish striking, it does not undergo plastic deformation like high carbon bearing steel. Since the swaging process of the difficult spindle blade is made easy, and the bobbin fitting part 27 to be fitted into the bobbin top hole is formed in the fourth step, the first to third steps are fixed. For spindle blade types (for example, the standard 7-inch lift type), there is no need to change the mold, and only the mold for the fourth process needs to be changed according to the customer's bobbin shape, making it extremely efficient. It has advantages such as being able to be manufactured efficiently and at low cost.
