(54) DEVICE FOR REMOVING DETAILS FROM A HANDLING ZONE

(57) The invention relates to cold pressure treatment of metals and may be used to remove parts from the treatment area. The goal is to increase reliability in work. Pressed parts are fed to the stepped tray. The tray is reciprocated in horizontal and vertical directions. The movement of the tray is communicated from the movable plate through a conversion mechanism. The latter contains a double-shouldered lever, hinged on a fixed plate and carrying on one of the wedge protrusion, and a toothed rack mounted on a movable plate. On the toothed rack, wedge sliders interacting with the wedge protrusion are mounted with the ability to move in the vertical direction. On the lateral sides of the tray, rails fixed at an angle to the axis of movement of the tray in the horizontal direction are fixed. Rollers mounted on a fixed plate move in the same direction. 4 il.

The invention relates to the processing of metals by pressure and can be used to remove parts from the working area of the punch.

The purpose of the invention is the reliability of work.

Fig. 1 shows a device for removing parts from the treatment area, a general view; in fig. 2 - section aa

in fig. one; in fig. 3 shows a section BB in FIG. one; Fig. 4 shows a casing with a wedge-Mji Lolzushka.

The device comprises a lower fixed plate 1 with a horizontal groove 2, a bracket 3, fixed, on the plate. 1, two shoulders lever 4, hinged by means of axis 5 on the bracket 3, tray 6, located in the groove 2 of plate 1. One end of tray 6, using axis 7, is hinged to one Sh-1M from the ends of two shoulders 4 The other end of the tray 6 is connected to one of the ends of the spring 8, the other end of which is connected to the slab.

On the side walls of the tray 6, at an acute angle to its longitudinal axis, inclined guides 9 are mounted, and in the slab 1, the rollers KI 10, the entrance sch1 {e into the guides 9 are mounted.

Tracks are located in a vertical plane.

On the upper movable plate 11, a gear rail is mounted, comprising a case 12, in which vertical guides 13 are made. In the guides 13, wedge slides (cams) 14 are mounted, spaced between the projections C and D, radiated in the housing 12.

At the upper end of the lever 4, a projection 15 is elongated, having bevels D and E,

On the plate 1 is mounted the matrix 16 with the stripper 17, On the plate 11 with the help of the punch holder 18 mounted

punches 19 for forming parts 20 from a strip or tape material 2 1.

The device works as follows.

When the plate moves .11 down, the half-emitter stick (cam) 14 acts on the bevel D of the projection 15. The double-arm lever 4 rotates around axis 5 and with its other end through axis 7 moves tray 6 in the horizontal direction, stretching the spring 8.

At the same time, tray 6, together with the steps, moves 20, upwards at an angle

scrap to the direction of removal of parts. Such movement of the tray 6 sets the inclined guides 9, which interact with the rollers 10 mounted on the bottom plate 1. Inertia forces when the tray 6 moves with the parts up at an angle to the direction of their removal press the parts to the surface of this tray and increase the traction forces between the tray and details. Upon further upward movement of the plate 11, the contact of the surface D with the lower bevel of the lower slider (cam) 14 stops 5 and the spring 8 almost instantly returns the tray 6 to its original position, turning the lower arm of the lever 4 in the opposite direction. At the same time, the upper arm of the lever 4 with a wedge-shaped bevel E acts on the upper bevel of the lower slider (cam) 14, moves it down, and with the wedge-shaped bevel D, I act on the lower bevel of the next polzupish (cam) 14, presses the elastic cams 14 to the projection G.

Thus, the tray 6 abruptly changes the direction of movement in the opposite direction and moves downward at an angle to the direction opposite to the direction of removal of parts, and then, by inertia, continues to move upwardly at an angle to the direction of their removal. This ensures that the parts are offset relative to the tray in the direction of removal. The next cam 14, the lower bevel, then interacts with the wedge-shaped bevel D of the lever 4 and the cycle repeats. The number of cycles is equal to the number of cams 14. At the center of the stroke of the plate 11, all the cams 14 are pressed down by the wedge-shaped bevel E to the projection B.

During upward movement of the plate 11, the bevels of the half-sleeves (cams) 14 alternately interact with the wedge-shaped bevel E of the lever 4, turning it around the axis 5, set the movement of tray b, which is similar to its movement during the course of the plate 11 downwards. 14 are pressed by the wedge-shaped bevel D to the projection G.
