SU1301532A1 - Arrangement for feeding blanks to working zone of press - Google Patents

Abstract

The invention relates to the field of cold metal forming, in particular, to devices for feeding piece blanks into the working area of a press. The aim of the invention is to increase the reliability of operation. The stock tray is fed into the loading area. When the press ram moves down, the gear rack is set in motion, which, through the pinion gear and shaft, drives the bushing with protrusions. The tabs interact with adjustable stops mounted on the gear, freely mounted on the shaft. The cog gear drives an additional toothed rack, bearing a spring-loaded grip relative to it. The gripper moves the workpiece to the working area of the press before interacting with the stop. In this case, the additional cogged rail moves, and the grip stands in place, compressing the spring located between it and the additional toothed rack. When the press ram moves upward, the additional rack bar moves to its original position under the action of the additional spring. 3 il. Q S € cl

Description

The invention relates to the field of cold metal forming and can be used to feed piece blanks into the working area of a press.

The aim of the invention is to increase the reliability of operation.

Fig. 1 schematically shows a device for feeding piece blanks into a working zone of a press; in FIG. 2, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device for feeding the piece blanks into the working area of the press comprises a housing 1 with a toothed rack 2 vertically disposed therein, cooperating with a gear wheel 4 mounted on a shaft 3 and connected to a horizontal pusher made as an additional gear rack 5. Gear 3 is mounted on the shaft 3 6. When this gear 6 is equipped with adjustable stops 7 and 8, placed on its end surface, and freely mounted on the shaft 3, which is equipped with a lead 9, made in the form of a sleeve with protrusions 10 and 11, interacting when rotating shaft 3 with stops 7 and 8.

In addition, the additional gear rack 5 is spring-loaded with a spring 12, equipped with a gripper, i.e. a spring-loaded pusher 13 with a shut-off device 14 and a limiting lever 15, which cooperates with a buffer 16 installed in the housing 1, and a vertical toothed rail 2 is connected; with slider

35, it returns to its original position, with the adjustable stop 7 interacting with the protrusion 10 of the driver 9. In the following, the cycles are repeated.

press 17 by means of, for example, a bracket 18 and a floating support. 19.

Claims (1)

The bracket 18 is rigidly mounted on the 40th Formula of the invention of the press ram 17, on which the Device for feeding the piece is set, calibrated stamp 20 with rigid preparations into the working area of the press, containing an abutment 21 and a bracket 22 on which the shaft located in the housing is unmounted housing 1. The device is equipped with an impeller, a gear shaft and a tackle with a chute 23 for blanks 24.45 ku, interconnected with a moving clock. The device operates as follows. From the orienting device (not shown), the workpiece 24 on the tray 23 is fed to the press zone, the press slider 17 is in its lowest position, and the gear rack 5 with the pusher 13 is in the initial position, while the protrusion 10 of the leash 9 interacts with an adjustable stop 7, and the lever 15 - with buffer 16. When raising the slide of the press 17 to the upper extreme position of the rail 2, moving simultaneously with the slide. press with the ability to move relative to it and interacting with a gear wheel, gear mounted on the shaft, an additional gear rack bearing the grip and fixed in the body with the ability to interact with the gear, in order to increase the reliability of work 55 it is equipped with a damper mounted in the housing with the ability to interact with an additional gear rack. When it is idle, adjustable stops mounted on Press 17, turning. The shaft 3 and the leash 9 turns against the clock hand, selecting an idle stroke, while the rack and pinion 5 is held in its original position by means of a spring 12 and a lever 15, which interacts with the buffer 16. With a further rise of the press slide 17 and the drive rail 2 leash 9, the interaction of the protrusion 11 with an adjustable stop 8 of the gear 6, leads it into the turn, and the rack and the rack 5 with its spring-loaded push rod 13 moves the workpiece 24 in the die 20 to the hard  5 stops 21, while compensating for the hard impact of the workpiece 24 against the stop 21, and the rest of the workpiece 24 located on the tray 23 are held by a cutter 14 mounted on a spring-loaded push rod 13. When the press slide 17 moves to the lowest position, the rail 2, moving simultaneously with the press slide 17, rotates  the shaft 3 and the leash 9 are clockwise, the spring 12 presses the adjustable stop 8 to the protrusion 11 of the leash 9 and the gear rack 5 with the spring-loaded pusher 13 returns to the initial position, and the stamping punch 20 performs a calibration operation: buffer 16, interacting with lever 15, extinguishes the inertia of the padded rail 5, and rail 2, choose a hollow 35, it returns to its original position, with the adjustable stop 7 interacting with the protrusion 10 of the driver 9. In the following, the cycles are repeated. The formula of the invention. A device for supplying piecework to the working area of a press, comprising a shaft located in a housing, not an injection wheel, a toothed rack interconnected with a moving part press with the gear and interacting with a gear wheel, gear mounted on the shaft, an additional gear rail carrying the grip and fixed in the body with the ability to interact with the gear, in order to increase the reliability of work it is equipped with a damper mounted in the housing with the possibility of interaction with an additional gear rack. when it is idle, the adjustable stops are mounted on gear, sleeve, rigidly mounted on the shaft, and protrusions made on the sleeve with the ability to interact with adjustable stops, gear mounted on the shaft freely, additional gear rack spring in the direction of the working area, and the grip is spring-loaded relative to the expansion gear rack in the direction of the working area.
