SU986550A1 - Apparatus for feeding and removing blanks to from working zone - Google Patents

Description

The invention relates to the mechanization of the loading of a billet and can be used in dies intended for carrying out various technological operations with tubular billets having low stability in the axial direction.

A device for applying blanks is known, comprising a lower plate, a blank magazine, a feeder with a gripping organ and a pin for fixing the blanks at the working position C1.

A disadvantage of the known device is its complexity and lack of reliability due to the presence of a large body of kinematic chains and automation elements.

The aim of the invention is to improve the reliability of the device.

The goal is achieved by the fact that the device containing the bottom plate, the magazine for blanks, the feeder p a gripping body and a pin for fixing the blanks at the working position is equipped with a drive-connected and movably mounted in the feeder body perpendicular to the feed direction with a slider with a bevel

and a groove, a roller lever in the middle part interacting with the slider groove, one end hinged on the bottom plate, and the other hingedly connected to the pin, a beveled stop fixedly mounted on the bottom plate. And interacting with its bevel with the slide bevel, and the pin spring loaded and

10 is movably mounted in the axial direction.

The device contains a magazine 1, a feeder 2 with a clamp-type pick-up body 3, the jaws 4 of which compress the workpiece 5 with a force developed by a spring 6, a pin 7 spring-loaded spring 8, a support bar 9 for limiting the lower position when the workpiece 5 drops from the shop 1 gripper 3. With pin 25 rem 7, lever 10 having roller 11 is interconnected. Feeder 2 has slider 12 with bevels a and b and slot B, the width of which is somewhat larger than roller width 11. Along the movement of feeder 2 is installed copier 13, and perpendicular to it - pusher 14. For control The position of the jaws 4 of the gripping body 3 at the grip position of the blanks are copiers 15 and 16. The device operates as follows. The blanks 5 in the form of pipe sections enter the magazine 1. In the initial position, the gripping body 3 of the feeder 2 is in the position of the billet, i.e. under the store 1. Sponges 4 gripping body 3 interact with copiers. 15 and 16, by opening the grip for the billet passage. The bottom billet, under the action of its own weight and the weight of the billet column, rushes down into the open clamp grip. When it reaches the support bar 9, the downward movement of the blanks stops. In this case, the bottom billet is installed in the gripping body 3. When the feeder 2 moves to the working position LUTciMna, indicated in the fig line by r-y, the gripping jaws 4 of the gripping organ 3 descend from the copiers 15 and 16 and due to the action of spring 6 the workpiece 5, keeping it from falling down after it has passed the support bar 9. The runner of the feeder 2 is pressed so that, with its extreme right position, the axis of the workpiece would coincide with the axis of the g-d stamp. When lowering the slider down, the press punch or pusher installed in the punch presses billet 5 from the top and pushes it down, overcoming the force of friction of the cutting tool 3 created by the force developed by the spring 6. As soon as pin 7 is deep enough will go into the central hole of the workpiece 5, the feeder 2 makes a move back to the loading position of the workpieces. Sponge 4 pickup organ gan. 3 free billet. The blank is at the working position of the stamp, on the pin 7. During the next cycle, the p-test 2c moves to the working position of the stamp, where the stamped part is located on the pin 7. The slider 12 of the feeder 2: using the bevel, is guided by the copier 13, installed along the movement of the feeder 2, so that the slit in the slider 12 passes away from the roller 11 mounted on the lever 10. The rollers 11 interact with the bevel of the slider 12, recessed , he is fascinated by rye. step 10 and the pin 7 associated with it, which frees the part. These movements occur quickly, the part does not have time to fall, and in the next instant it is dropped by the end face of the gripping body 3 into the receiving container, freeing up space for a new billet. In the extreme right position of the feed ;; I 2, the roller 11 stops contact with the slider 12 and is released. Pin 7 due to the force of the spring 8 returns to its original position for. receiving another billet. The feeding of the workpiece by the feeder 2 to the working position of the stamp occurs when the press ram is raised and ends before the press ram reaches its extreme upper position. In the remainder of the time, the press slide moves the pusher 14, which is set perpendicular to the movement of the feeder. 2. The pusher 14 in turn places the slider 12 so that the slit in turns out to be just opposite the roller 11 and the next movement of the feeder 2 to the left, to the loading position of the blanks, the roller 11 freely passes through the slit in, without pressing; and do not release the next billet installed on it. After the passage of the roller 11, the slider 12 begins to interact with the cam 13, returning to the position for the next interaction with the roller 11, moving the feeder 2 to the right to the position; downloads. Then the cycle repeats. The drive for the reciprocating movement of the feeder 2 and the pusher 14 are flat copiers designed for longitudinal movement and mounted on the top plate of the stamp. i The device automates the feeding of workpieces to the working position and the removal of finished parts, eliminates the use of manual labor, improves the stamp performance. Claims An apparatus for feeding and removing blanks from a working area of a press, comprising a bottom plate, a magazine for blanks, a feeder with a gripping organ, and a pin for fixing preparations in the working position, characterized in that equipped with a drive-mounted and movably mounted in the body of the feeder perpendicular to the feed with a ram with a bevel and a groove, a lever with a roller in the middle part, interacting with the groove of the ram, with one end hinged on the bottom plate and others pivotally connected to the pin, beveled by the HbiM ynopoM, fixedly fixed On the bottom, slide and interacting with its bevel with the bevel of the ram, the pin is spring-loaded and movably mounted in the axial direction.
