Abstract

BUNKER LOADING-ORIEN THREATING DEVICE, which contains a bunker, a slit sector with a drive, a discharge tray and a nera - VILNO oriented billet dumper, characterized in that, in order to improve the reliability and simplify the design of the device, the resetter has been made in the back of the fitting, two shoulders with mutually perpendicular rym arrangement of shoulders and a slide, installed with the ability to interact with one end of the shoulder spring-loaded two shoulders, and the other with a slit sector m, wherein the second double-armed lever arm pivotally mounted transversely slit sector.

Description

The invention relates to mechanical engineering and can be used to automate steps of cylindrical stepped billets such as flanged axles, bolts, screws, rivet screws, in which the length-to-shoulder diameter ratio is greater than one. The purpose of the invention is to increase reliability, simplify the design of the device by ensuring that the incorrectly oriented workpiece is reset. and simplify the dropping drive. Figure 1 shows the device, the section in figure 2 - the position of the two shoulders at the time of resetting an improperly oriented workpiece; in FIG. 3 - section A-A in FIG. 1 in FIG. 4 is a view along arrow B in FIG. 3; Figures 5 and 6 show the positions of incorrectly oriented blanks. The bunker loading-orienting device for removing stepped cylindrical blanks consists of the bunker 1, the slotted sector 2., And the tapping tray 3 (Figures 1 and 3). The aperture sector 2 is pivotally connected to the hopper 1 via axles 4, and the lever 5 is pivotally connected by means of an axis 6 to the rod 7 of the actuator 8. The actuator 8 is axially 9 connected pivotally to the bracket 10 of the bunker 1. The slit sector 2 is positioned relative to the vertical wall 11 of the bunker 1 The billet 12 is installed with a swinging motion relative to the wall 11 and the axis 4. The ejector 13 of incorrectly oriented billets 14 (FIGS. 1-4) contains a movable plate 15 fixed with bolts 16 with the possibility of By means of the grooves 17 relative to the vertical wall 11 of the bunker 1. On the plate 15, the supports 18 and 19 are rigidly fixed, in which a spring-loaded arm 20 is located, mounted on an axis 21 with the possibility of angular rotation and consisting of a short arm 22 and a long arm 23, placed in perpendicular planes. A pin 24 is rigidly attached to the axis 21 on which one end of the tension spring 25 is fixed, the other end of the spring is fixed on the plate 15. A support 26 is rigidly mounted on the plate 15, in which the slider 27 is positioned to move the slider 27 with the possibility of moving the slider 27, in which a pin 29 is mounted, rigidly fixed in Slider 27. Slider 27 is associated with a shoulder 22 of the lever 20 and an emphasis 30. slotted sector 2. To a discharge tray 3 with a screw 31 with the possibility of vertical movement attached receiving tray 32. In the front wall 33 of the hopper 1 there is a window 34 for accommodating the Slot sector 2 and providing a flow outlet for correctly oriented workpieces 12. In FIG. at the moment of dropping an improperly oriented workpiece 14 with the extreme upper position of sector 2, FIG. 5 shows an incorrectly oriented workpiece 14, the shoulder of which is clamped between the flow of correctly oriented workpieces 12 and the over days wall 33 of the hopper 1. The device operates as follows. In the initial position, the slotted sector 2 is at the bottom, the rod 7 of the actuator 8 is in its extreme upper position, the shoulder 23 of the spring-loaded two-arm lever 20 is pressed against the vertical wall 11 of the bunker 1 by the spring 25, the short shoulder 22 is free, the slider 27 is in the lower position, and the pin 29 rests on the bottom wall of the groove 28 of the support 26. The receiving tray 32 is set to the desired length of the workpiece 12, the ejector 13 by means of the slots 17 is extended above the hopper 1 so that, in the upper position of sector 2, the workpiece 14 is reset as shown in FIG. Before starting the operation. The movable plate 15 of the dumper 13, as a result of the presence of the grooves 17, is positioned relative to the vertical wall 11 of the hopper 1 so that the stroke of the slide 27 provides a sufficient rolling angle of the spring-loaded two-arm 20 to reset the blanks 14 from the sector. Billet 12 is loaded into the bowl of the hopper 1 in bulk, after which the actuator 8 is turned on, while its rod 7 is reciprocating, through the lever 5 it transmits rocking movements to sector 2 (Figures 1 and 3). When moving sector 2 up the workpiece sink into the slot

sector 2 and shoulders abut the top surface of the sector, oriented vertically.

When the subsequent rise upwards, the correctly oriented workpieces 12 slide along the inclined surface of sector 2 and sink into the vertical opening of the discharge tray; this lower end of the workpieces 12 slides and is guided along the receiving tray 32. The workpieces 12 in. oriented position along the discharge tray 3, toward the processing machine.

In the extreme upper position, the slit sector 2 by the stop 30 moves the slider 27, which with its upper end presses the shoulder 22 of the spring-loaded two-shouldered lever 20 (FIGS. 1-4). The lever 20, turning around the axis 21 on the supports 18 and 19, the second shoulder 23 captures and dumps into the bunker bowl incorrectly oriented blanks 14, which lie on top of the heads of the correctly oriented blanks 12 located in the slot of sector 2 (Fig.2.5 and 6).

As sector 2 moves downward, the anvil 30 detaches from the slider 27 and the anchor 26, lowers the pin 29 into the bottom wall of the groove 28 downward until it stops, supporting its own weight. Under the action of the spring 25, the shoulder 23 of the spring-loaded two-arm lever 20 is pressed against the wall 11 of the bunker 1. Then the cycle repeats.

10 An emphasis 30 is placed on the edge of the sector and, at the moment of interaction with the slider 27, it leaves the freedom bin; from the surface of sector 2 is carried out at the front wall of the bunker 1 before leaving the blanks from the bunker; therefore, the shoulders of the spring-loaded two-arm lever 20 are placed in different planes.

20 Thus, regardless of the position of the workpieces in the device bunker, a securely oriented stepwise cylindrical billet type axis is provided.

Volume 25, bolts, screws, screws, rivets, having a ratio of the length and diameter of the collet more than one.
