Description

The invention relates to a process mechanized punching production line, in particular, devices for unloading blanks, preferably sheets, which are heat treated from a walking beam furnace and transported to a press for pressing.

The aim of the invention is to increase the productivity and quality of heat treatment of blanks by reducing the time of transporting blanks from the furnace to the press and expanding the range of processed blanks.

The mechanized heat treatment line for billets contains a furnace 1, for example, with walking beams, a manipulator 2 and a press 3 with a punch. The manipulator 2 is located between the furnace 1 and the press 3 and has a turntable 4 on which the guides 5 are placed. Moving the guides 5 along the vertical direction mechanism 6, and the turn - mechanism 7 On the guides 5 moves the mechanism 8 movement part 9, nz

SP

the working body 10 is fixed in the form of forks for holding the blanks 11. The manipulator 2 is provided with an equalizer 12 mounted on the guides 5 on the fixed platform 13 with the possibility of longitudinal-lateral movement relative to the longitudinal axis of the manipulator. The working body 10, made in the form of a fork, is provided with grippers 14, which are driven by a mechanism 15 in the vertical plane,

Mechanized line works as follows.

The blank 11, subjected to heat treatment in the heating furnace 1, is supplied by walking beams to the furnace unloading window. The mechanism 8 moves in the radial direction of the chassis 9, while the working body 10 in the form of a fork moves along the guides 5 towards the heating furnace 1. enters between the fixed beams, the movable beams are in the lower position when unloading the blanks. The mechanism 15 for driving the grippers 14 is activated, which, with their jaws, fix the workpiece 11 on the working element 10 in order to eliminate its vertical imbalance. Then reversal is performed and the running part 9 returns to its initial position along the guides 5 under the action of mechanism 8. Thereafter, drives of a longitudinal-lateral movement (for example, hydraulic or pneumatic or electric) of equalizers 12, mounted coaxially on the guides 5 on the platform 13, are included in series to ensure accurate orientation of the workpiece 11 in the horizontal plane relative to the longitudinal axis of the manipulator 2 After leveling the workpiece 11, the mechanism 7 rotates the table 4. In this case, the guides 5 with the running gear 9 mounted on them and the working body 10 holding the workpiece 11 are turned District vertical axis of the manipulator 2 by a certain angle to the coincidence of the axes of the manipulator 2 and 3. The press mechanism 6 is switched vertical movement, the guide 5, carriers 9 running gear with a working body 10, are raised above

the level of the rotary table 4. Then a signal is given to turn on the mechanism 8 and the running part 9 moves into the working area of the press 3. The reverse of the vertical movement mechanism 6 is turned on, the guides 5 are lowered and the workpiece 11 is fed to the press stamp 3 under pressure treatment.

The manipulator is returned to its original position in the reverse order.

The stamped workpiece is removed from the press on the opposite side with a special device.

The control of the heat treatment line mechanisms can be carried out either from the operator’s console or in automatic mode.

The invention will improve line productivity by reducing the time of transporting the blanks from the furnace to the press, associated with the fast orientation of the heated blanks to be fed to the press stamp by the leveler, and will also improve the quality of heat treatment of the blanks by eliminating possible distortions and stops of the blanks and associated cooling of the blanks. The presence of the drive grip also contributes to the processing of a diverse assortment of blanks.
