Description

The invention relates to the mechanization of press forging and can be used to remove parts from the working area of presses.

The aim of the invention is to expand the technological capabilities of the device by ensuring the forced removal of the stamped parts from the working area of the press. This goal is achieved in that in a device for removing parts from a press working area having a die plate movable and stationary with a punch, including a gear rack mounted parallel to the plate movement, mounted to engage a pinion gear connected thereto. the last driven gear that is in engagement with the toothed rack, the last being the pusher, is fork-shaped and can be moved in the direction of removal of the part, while the punch is provided with two side grooves and forms

forked gear rack translational pair.

.1 shows a device, side view; figure 2 is the same in plan; in Fig.Z - section aa of Fig.2.

. The device for removing parts from the working area of the press contains a movable plate 1, a fixed plate 2, on which a punch 3 with grooves 4 is mounted. The rail 5 is mounted on the movable plate 1 of the stamp using a support 6 and is oriented using a support 7 mounted on a fixed plate 2 stamp. . The gear rack 5 is meshed with a pinion gear 8 mounted on the shaft 9. On the shaft 9 there is also a driven gear 10 which is meshed with the gear rack 11 of a fork shape. The gear rack 11 is mounted in a guide 12 mounted on a fixed plate 2. The shaft 9 is mounted in bearings 13, also mounted on a fixed plate of the stamp. The removable part 14 is shown on the punch 3 in the position after stamping.

The device operates as follows. In the initial position, the movable plate 1 of the press is in the upper position, and the gear rack 11 is in the leftmost position. When the press is turned on, the movable plate 1 moves down. The same movement is made by the rail 5 fixed on it in the bearings 6 and 7, which, interacting with the drive gear 8, rotates it, and, therefore, the shaft 9 comes into rotation in the bearings 13 and the gears 10 mounted motionlessly mounted on it. The latter communicates the forward movement of the toothed rack 11 in the guide 12. As a result of this movement of the gear rack 11 leaves the interstamp space. At the time of the stamping act, the latter is in the rightmost position. When the movable plate 1 moves upward, the tooth-shaped rack 11 moves in the opposite direction, covers the punch 3 with its longitudinal groove and forcibly pushes the part 14 remaining on the punch in the direction of its movement.

Next, the cycle of removing parts from the working area of the stamp is repeated.

The proposed technical solution allows, in comparison with the prototype, to expand the technological capabilities of the device. This is achieved by the fact that the toothed rack acts as an ejector de-

hoist, while in the prototype it performed only an auxiliary role: it carried an element that received a stamped part for further movement and was stamped onto it by an additional ejector device. This technical solution simplifies the design of the device, kinematically connects the movement of all elements of the device with the movement of the movable die plate, which leads to savings, in comparison with the prototype, of the energy carrier (compressed air). SUMMARY OF THE INVENTION A device for removing parts from a press working area having a slider and a fixed table with a punch comprising a vertical gear rack, a driven gear mounted on a shaft, and a leading vertical gear rack mounted for reciprocating movement and interacting with the driven gear, puller with a gear surface, mounted to interact with the driven gear and with the possibility of horizontal movement, characterized in that, in order to expand functionality by ensuring the forced removal of the stamped part from the punch, two side grooves are made in the punch, and the puller is made in the form of a fork and is installed with the ability to interact with the grooves of the punch.
