Description

The invention relates to the processing of metals by pressure, in particular, to mechanical devices and automatic devices, and can be used to remove parts from the working area of a punching press during the production of various production processes in the closest to the invention and its technical essence. the effect achieved is a device for removing from the working area a punching press, containing its tray, by connecting an adjustable length arm to a rotary shaft, installed in the lower part of the station s press, the system controlled by the length of the levers, the mechanism of orientation of the tray position, turn conductive thrust ,. associated with the tray 1. The disadvantage of this device is the fact that it can remove only a small number of small parts from small-sized punches from the working area of the stamping press. The aim of the invention is to expand the technological capabilities of the device by increasing the size range of parts to be removed from dies of various dimensions. The goal is achieved in that in the device for removing parts from the working area of a punching press containing a tray connected by a length-adjustable lever with a rotary shaft mounted in the lower part of the press frame, a system of length-adjustable levers and a tray position orientation mechanism. including traction connected with a tray. The orientation mechanism is equipped with two horizontal guides, the tractor is connected to the tray with the possibility of an angular displacement relative to the last in the vertical plane and is equipped with a roller mounted on the other end and placed in a direction with the possibility of reciprocating movement, the tray is provided with at least two remote rails mounted for movement relative to the tray along and across its longitudinal axis. In addition, the device is equipped with an additional link connected with the lot: a lump and a guide, and additionally an HtjM lever, which is lengthwise and connected to the chute and the rotary shaft, is made similarly to a lever that is adjustable and longitudinally adjustable. The arms and length-adjustable levers are located at the ends of the thread. On figl shows the device in the lowest position of the crawl, and the press, a general view; in FIG. 2, section A-A in FIG. one; on fig.Z section bb in Fig .; 4 shows the device with the extreme lower polo. scissor, right side view; in Fig. 5, view B in Fig. 3; figure 6 - section GG in figure 1; figure 7 - section dD in figure 1. The device for removing parts from the working area of the punching press contains brackets 1 and 2, respectively, mounted on the press ram and in the lower part of its bed. In bearings 3 of brackets 2 a rotary shaft 4 is installed with adjustable lateral levers 5 connected with levers b, which are connected to brackets 1. Adjustable adjustable locks fixed on a rotary shaft 4; length 7 levers installed at base 8 with lid 9 and containing pipe 10, sleeve 11c left-threaded, pipe 12 with left-handed thread, lock nut 13, sleeve 14 with right-handed thread and screw 15 with right-handed thread. Adjustable levers 7 are hingedly connected to a tray.16, on the side walls of which 17 are mounted toothed strips 18, connected by means of a bolt 19 and a nut 20 to the toothed strips 21, lips; on the hooks 22 on the roller 23, the orientation mechanism of the tray 23. The orientation mechanism of the tray also contains two horizontal guides 24 rigidly mounted on the press slider. The rollers 23 are placed in the guides 24 with the possibility of reciprocating movement. In the bars 18 and the sides 17, a groove 25 is made. On the tray 16, clamps 26 of the extension rails 27 are installed. Each clamp 26 has clamps 28 fixed to nut 29 by means of pins 40, stop 31, screw 32, handle 33. The device operates as follows hand 3 When the press ram moves upwards, the brackets 1 move with it, which by means of levers 5 and 6 rotates the rotary shaft 4, the levers 7 and the associated tray 16 with external rails 27 and the rods 22, the rollers 23 of which move in the guides 24. When This remote rails 27 are introduced into the work area. In the extreme upper position of the press ram, the stamped part drops onto the external rails 27 of the tray 16, and during the return of the press ram down, the external rails 27 of the tray 16 exit the working zone 11. and remove the part to the container. Then the cycle repeats. When changing the stamp, the device is not removed from the press. In the extreme upper position of the slider, sufficiently detach the levers 6 from the crocheins 1 and turn them relative to the levers 5 from the press to the extreme lower position. The pulleys 22 are driven out by their roles 23 from the guides 24 and also j are rotated together with the chute 16 v relative to the levers 7 from the press to the lowest position. After changing the stamp, the device returns to its original position and adjusts to the new part. At the same time, by changing the length of the levers 5, the stroke of the tray 16 is adjusted, by changing the length of the levers 6, the amount of extension of the rails 27 to the working area is established, and by changing the length of the lever 7, the guaranteed clearance between the rails 27 and the lower part of the stamp is achieved. To change the length of the lever 7, it is necessary to unscrew the nut 13, turn the tube 12 to the right or left instead of the sleeve 14, into which is screw 15, connected to the tray 16, relative to the sleeve 11 fixed in the pipe 10 fixed in the base 8. When the required length is reached The lever 7 tightens the lock nut 13. Adjustment, position g 22. provides guaranteed clearance. between the top of the stamp and. . the removable rails 27 of the tray 16. To change the position of the plugs 22 relative to the tray 16, unscrew the nuts 20 by the number of threads required for driving the toothed strips 21 from the gears 18 mounted on the sides of the 17-tray 16. The tees 22 together with the toothed ones the strips 21 are rotated relative to the tray 16 by the required number of teeth of the slats 18 up or down. The bolts 19 move along the grooves 25 together with the rims 22, and then tighten the nuts 20. To adjust the outrigger rails 27 of the tray 16 in width and length, it is necessary to unscrew the screw 32 of the clamp 26 for the required number of turns from the stop 31 In this case, the nut 29 moves downward from the tray 16 together with the screw 32, and the claws 28 connected with the stop 31 by the pins 30 are pressed from the extension bar 27 of the tray 16. The extension bar 27 together with the clamp 26 moves by the desired amount along the tray 16, then the rake 27 is moved relative to the rail. clamp 26 across tray 16 for the required amount, after which it is pressed against tray 16 by rotating the presser 33 of clamp 26. The proposed device allows for the removal of parts from a wide working range of sizes from dies of various sizes.
