SU124269A1 - Device for feeding, for example car liners, to vertical piercing machines - Google Patents

Description

The existing devices with a magazine, in which the blanks with their weight are lowered along the chute to the site and from there are pushed through one brush to the treatment area, are suitable for bodies of rotation (punching, fingers, rings and other parts).

The proposed device is intended for automatic feeding in vertically-piercing machines of parts such as automotive liners. This device uses a carriage for moving liners to the working position, provided with a folding support platform for pre-receiving the raw product and pull-out swivel hooks for securing the product in the slot of the carriage as it moves. In the gutter-shop of this device, spikes and guides are used to load manufactured products.

FIG. 1 is a schematic longitudinal section of the device with the magazine removed; in fig. 2 - device in plan; in fig. 3 - longitudinal section of the store; in fig. 4 - the dumper, in the plan.

The proposed device is made on the basis of a vertical piercing machine for flashing car inserts, and consists of a magazine / and carriage 2, equipped with a folding platform 3 and a socket 4 and having pivot hooks 5.

Shop 1 is located above the carriage 2 and secured with vertical bolts at three points 6, two of which are located on the side racks 7 and one on the right ledge of the housing 8.

The workpieces of type 9 of the insert are loaded by a stack manually into the vertical channel 10 of the magazine / and guided there by a ruler // and guides 12. The lower part of the product enters the head of the resetter 13 and is individually guided by a ruler 14 and guides 15. The entire stack of processed products 9 lying on the stove.

No. 124269-2 -

The ejector 13 presses from the bottom to the magazine case / and is guided by the lid 17. A spring 18 is pressed into its notch, abutting with a pin 19 at one end, and pressing the ejector 13 at the second, resulting in the ejector with its bolts screwed into the hole 20, resting the cover 17.

When the carriage 2 moves in the direction of arrow M, it hooks the resetter 13 with the strap 21 and, compressing the spring 18, retracts it to the extreme right position, as a result, together with the resetter 13 the lower workpiece 9 moves to the right, which then goes down to the folding platform 3. Simultaneously the dumper 13, with its upper plane, cuts off the entire stack of the remaining processed products 9, preventing them from falling down.

To direct the workpiece to fall on the folding platform 3, a folding sector is provided on the plate 16, and on the ruler 14 there is an extension ruler entering the zone of the carriage 2 and folding as it moves.

A folding platform 3, entering the slot of the socket 4 of the carriage 2, is highlighted on the axis 22, around which it can rotate; being pulled down by the spring 23, it moves together with the carriage 2 and at the moment when the carriage 2 is in the extreme right - boot - position, its lower side lies on the T-bolt 24, which prevents it from falling down.

When the workpiece 9 enters the folding platform 5, the carriage 2 together with the folding platform 3 begins to move in the opposite direction, along the arrow N, to the brooch, and the hooks 5 under the action of the spring 25 begin to pull the processed product 9 into the slot 4. T-shaped The shoulder of the bolg 24 is selected so wide that during the sliding on its surface of the folding pad 3 the hooks 5 have time to firmly hold the workpiece in the nest 4. Pass through the bolt 24, the fold pad 5 under the action of the spring 23, turning around the axis 22, falls down and arr The batten 9, clamped with hooks 5 in slot 4, is fed under the broach of the vertical piercing machine and the grommets are locked in slot 4. Two pins that are longer than the brooch are fixed on the shoe of the machine brooch, so that when the brooch is lowered down, they press on the side projections 26 hooks 5 and unfold them, giving a free passage to the brooch producing the piercing of the workpiece 9.

When the carriage 2 moves in the direction of arrow N on the brooch, the ejector 13 under the action of the spring 18 also begins to move in the direction of arrow L until the bolts screwed into the holes 20 into the guide cover 17, then the ejector 15 guides coincide with the guides 12 of the vertical channel 10 of the magazine The entire stack of workpieces 9 is lowered down and the bottom workpiece is lowered into the head of the dumper 13.

After the machined product 9 is flashed, the carriage 2 again begins to move to the right, in the direction of arrow M. The processed product 9, which sits in slot 4, abuts against the ejector 27 and is thrown from slot 4 into slot 28 and then slides onto the conveyor belt. The tilting pad 3 hits the T-bolt 24 and rotates to its original position to receive the next workpiece 9.

The rollers 28, worn on the ends of the brackets 29, with which the hooks 5 abut against the protrusions of the fixed symmetric copiers 30, rolling along their curve, unfold the hooks 5 to their original position.

The process is repeated.

The described device automates the supply of processed products to the machine and increases its productivity.
