Abstract

PURPOSE:To prevent deflected abrasion of a buffer material and gnawing of an engaged face and to easily execute assembling and working, by constituting an engaged inclined face of a drive cam and a slide cam in an engaged state at all times without the buffer material, and fitting the buffer material to the press- contact face of the moving side and the drive cam. CONSTITUTION:An upper holder 1 descends from the top dead center of a press, a work W is pressed against a punch 11 by a pad 12, and thereafter, a press- contact face 1a of the upper holder 1 is made to press-contact with a buffer material 23, and a drive cam 1 is depressed. As a result, the drive cam 15 is guided to a casing 14 and a holding hole 16 of a give plate 17 and descends while compressing a coil spring 22, and its engaged face 15a slides down along an engaged face 18a slide cam 18. Subsequently, the slide cam 18 compresses a coil spring 21, is guided to the casing 14 and the give plate 17 and advances, and desired working is executed to the work W by a pierce punch 10.

In general, forming a workpiece (hereinafter referred to as "work") with a punch Kt2 fixed on a fixed side by changing the direction of the operating force on the movable side and transmitting it to the slide cam on the fixed side via a drive cam. For example, as shown in FIG. 1, a conventional cam mechanism is used in a press machine that is busy for machining or drilling.

On the movable side, the lower surface of a drive cam 2 fixed to a vertically movable upper holder 1 forms an inclined surface 2a having a required angle θ, and an upper wear plate 4 is bolted to the drive cam 2 via a cushioning material 3. On the other hand, on the fixed side, a slide cam 7 that slides in the transverse direction on a slide pedestal 6 fixed to a fixed lower holder 5 is placed corresponding to the upper holder 1, and the rear surface of the slide cam T ( (in the figure, on the right), the inclined surface 7 with an angle θ
A is formed on the upper surface, and a lower wear plate 9 is similarly bolted to the upper wear plate 4 via a cushioning material 8, and a piercing punch 10 as a processing tool is provided on the front surface. Note that the punch 11 is fixed to a required position VC of the lower holder 5 corresponding to the piercing punch 10, and the workpiece W is placed on this. Reference numeral 12 denotes a pad that is movably held on the upper holder 1 via spring means (not shown).

Due to the slanted configuration, the upper holder 1 operates and descends, and the pad 12 first contacts and presses the workpiece, and then
The upper wear plate 4 of the drive cam 2 is attached to the slide cam 7.
When it comes into contact with the lower wear plate 9 and further descends, it slides on the engagement surfaces 15 that are inclined by θ degrees, and the operating force on the movable side is 9
Since the direction is changed by 0 degrees, the slide cam 7 moves forward (
(to the left in the figure), and the piercing punch 10 cooperates with a button die (not shown) provided in the punch 11 to perform the required processing on the workpiece WK. This is to reduce the impact when the plate 4 and the lower wear plate 9 engage, thereby preventing noise and vibration.

However, in such a conventional cam mechanism,
The upper wear plate 4 attached to the drive cam 2 and the lower wear plate 9 attached to the slide cam 7 may come into contact and separate, so even if a cushioning material is used in the valve device 7, noise may still be generated. There was a problem that vibration occurred. In addition, since the cushioning material generally uses a material with an elastic function, it is difficult to fix the wear plate in a fixed position.Furthermore, due to the cam mechanism, the wear plate and the cushioning material are subjected to a force perpendicular to the surface. Instead of receiving force, a diagonal force is applied to the surface, which can cause uneven wear on the cushioning material or galling on the wear plate. Furthermore, since the POL-F with the wear plate and cushioning material attached is repeatedly subjected to diagonal forces, it is easy to cause play, which can become a source of noise and vibration, and also cause the engagement surface to become misaligned. There was an interlude.
