Abstract

The invention relates to the processing of metals by pressure and can be used to accommodate piece blanks. The purpose of the invention is to increase the productivity of the placement of blanks. The blank is stacked in the cassettes. The cassettes are located around the turntable. The feet are moved vertically by a movement mechanism mounted on the bed. The turntable is mounted for movement in the vertical direction and removal from the bed. The turntable is moved in the vertical direction by the ram of the power cylinder through a conical sleeve interacting with a tapered cup mounted on the turntable. The body of the power cylinder is mounted on the frame, and the rod is fixed on the piston of the power cylinder. The turntable is driven into rotation by a drive through a gear freely mounted on the body of the ram. The pinion is secured in the gear, which is included in the vertical grooves made in the sleeve. The sleeve is mounted in a conical glass. 5 il.

Description

one

The invention relates to the processing of metals by pressure and can be used to accommodate piece blanks.

The aim of the invention is to improve the performance of the placement process.

FIG. 1 shows a device for placing piece blanks embedded in a flexible cold stamping production module; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. one; in fig. 5 shows the node I in FIG. four.

The flexible cold stamping production module contains a punching press 1 with a die-changing device 2, an automated transport and storage system including a rack 3 for die tooling and detachable tables 4 with blanks, and a stacker 5 moving along path 6. On a plate

The device 2 for changing dies by means of a bracket 7 is installed a manipulator 8 with electromagnetic grippers 9, in the cases of which sensors for the presence of parts are mounted. The left gripper is intended for putting the blanks from the cassettes of the removable table 4 into the intermediate stencil 10 of the stamp, the right gripper for transferring the blanks from the stencil to the stamping zone. Removable table 4 mounted on the frame 11, made in the form of a disk, in the center of which is fixed a conical centering cup 12 with a crown sleeve 13 having lead-in chamfers 14 and longitudinal grooves 15. The grooves 15 interact with pins made in the form of fingers 16 mounted on the hub of the gear 17 mounted on the body of the power cylinder 18 The gear 17 is engaged with the cogwheel gear

air motor 19 mounted on the plate 20, which is mounted on the power cylinder 18. On the opposite side on the plate 20 mounted mechanism for lifting the stack of blanks in the form of a cylinder 21.

The base of the power cylinder 18 is fixed on the frame 11, which is mounted on the drive carriage 22, and its rod is provided with a lead-in conical sleeve 23, which is rotatably mounted. The drive carriage 22 has the ability to mix from a working position to an overload zone along guides 24 located perpendicularly to the travel track 6 of the piler 5.

In addition, there is a vibrating channel 25, a container 26 for finished products and a control system with a console 27.

The model works as follows.

In accordance with the program of work recruited from the control panel 27, the stacker 5 takes the stamp from the desired cell of the rack 3 and delivers it to the device 2, which removes it, moves it to the working area of the press 1 and fixes it. Next, the stacker 5 removes from the rack 3 corresponding to this stamp table 4 with blanks, pre-laid in the cassette in the procurement area, and moves it to the overload position. At the same time, the bed 11 is moved to the same position. A command is then given to extend the rod of the power cylinder 18, the sleeve 23 of which enters the cup 12 and lifts the table 4 with the blanks, releasing the fork fork of the stacker 5, which is then pushed. A command is given to lower the table, during which the sleeve 13, interacting with the fingers 16, unfolds the table, orienting it to its original position. The drive of the carriage 22 is turned on, which moves the frame 11 with the table 4 with the blanks to the working position. In the working position, one of the grids 4 is positioned under the left electromagnetic gripper 9 of the manipulator 8. A command to lift the stack of blanks is sent to the cylinder pusher 21. At the moment of contact of the workpiece with the electromagnetic gripper 9, the part presence sensor turns off the cylinder 21, the pusher brakes and serves sequentially commands for lifting, gripping to a predetermined position, lowering and disabling them. In this case, the workpiece is initially placed in an intermediate stencil 10, which is simultaneously a lubricating position (not shown). During the next cycle, the workpiece is transferred to the stamp, the working stroke of the press 1 is performed, after which the stamped part is removed with a stream of compressed air to the vibrating channel 25, which takes it out of the press and drops it into the container 26. After emptying the cartridge, the cylinder 21 is lowered, the stepper air motor 19 is then turned on, turning the table 4 with the next cassette under the gripper of the manipulator 8. The cycle of the stitch 0 is repeated. After emptying all the cassettes, the device for moving workpieces with the waste table is moved to the overload zone to interact with the stacker 5, which removes the table 4 with empty cassettes and transports it to the harvesting area. Further operation of the module in the automatic mode takes place in accordance with the program laid down or by the operator's commands from the console 27 in the manual control mode.
