Abstract

The invention relates to the processing of metals by pressure, in particular, to a method and apparatus for transporting heated billets such as rotation bodies from a conveyor to a die of a stamp. The purpose of the invention is to increase productivity by eliminating jamming of the blanks. The method consists in that an additional force of displacement is applied to the workpiece in a direction perpendicular to its longitudinal axis and coinciding with the direction of rotation of the workpiece. A device for feeding heated billets comprises a conveyor, a horizontal movement mechanism with a pusher and a grab, a guide tray with a mechanism for rotating the workpiece. The heated workpieces are driven along a rotating drum into the grip of the horizontal movement mechanism and, by command, are transmitted by the pusher along the guide tray into the stamp. 2 s.

Description

The invention relates to the mechanization of metal forming processes, in particular, to methods and devices for supplying blanks, preferably heated, from a conveyor to a die.

The aim of the invention is to increase productivity by eliminating jamming of the blanks.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view.

The method is carried out as follows.

The heated workpiece moves along a predetermined route, while rotating around its axis, as it approaches its loading position, an additional effort is applied to the side surface of the workpiece in the direction perpendicular to its rotation axis and coinciding with the direction of rotation of the workpiece.

The device contains a conveyor (not shown) feed blanks in the stream of the stamp 1.

The horizontal movement mechanism 2 consists of the actuator 3, the pusher 4 and the grip 5, which is cantilever-mounted on the body 4, as well as the guide tray 6 with the built-in mechanism 7 of rotation of the workpiece. The mechanism 7 of rotation of the workpiece is made in the form of a drum 8 with a screw surface 9. The gripper 5 is equipped with a shutter 10. At the bottom of the gripper 5, facing the guide tray 6, a window is made, and in the end part there is a stop 11. The device is equipped with a sensor 12 blanks.

The device works as follows.

The blank 13 is fed along a conveyor from a heater (not shown) to the rotating drum 8 of the rotation mechanism 7, captured by a screw surface 9, unwound and fed into the gripper 5 up to the stop 11. On command from the sensor 12, the actuator 3 of the horizontal movement mechanism 2 moves by means of a pusher

4, the gripper 5 and thus rolls the proposed method provides more than a blank 13 on the supporting surface, the high reliability of supplying the blank to the steering tray 6 to the punch 1. A directional stamp. The number of failures in the baseline rotation of the workpiece 13 coincides with a weld that is 6.5 times greater than with the direction required to re-g the proposed method, rolling on the supporting surface of the guide tray 6. The stroke of the pusher 4 you-Formula of the invention is taken so that billet, rolling, for example, on the stamp mirror, j, the method of supplying bodies such as bodies could get into the stamp stream. The presence of rotation, predominantly in the heated cutter 10, in the device allows, in turn, for transporting the piece 13 to the grip of the line rotating the workpiece rotating around its axis and adding an additional example to it. Comparative displacement tests are carried out, characterized in that, according to the proposed increase in productivity, in addition to the method and device and in the base version -15, an extra displacement force is applied to the workpiece in the direction, perpent. Comparative test data are summarized in table. diagonal of its longitudinal axis and coinciding with the direction of rotation of the workpiece. Total number of blanks submitted520 Number of failures 27 Number of failures,% 5.1 When conducting comparative tests on installations with different ways of supplying billets, use is made of billets 020 mm, 60 mm long, heated in an induction furnace up to 1000 ± 10 ° С.
