Description

The invention relates to the processing of metals by pressure, in particular to sheet metal stamping, in particular to automated complexes for multi-transitions.

The purpose of the invention is the expansion of the technological capabilities of the device and the improvement of the production of the Neutrality of nroness ngammenovki.

FIG. 1 is an example of nggamnusma dehali; on (|) 2 - 1hump, vertical section in the plane, perpendicular to the front of the press (section B-B in Fig. 3); in fig. 3 is a device, a section in the plane, naralla; 1–1 Nress front (section A – A on phi1. 2).

The device consists of a vertical npocToi press o action 1, a multipositional P1 stamp containing a top nlit 2 connected with the press shoulder and a bottom plate 3 with a press table. On the top roll 2, fixed with plunger holders 4 6 respectively exhaust hoods

first and subsequent transitions 7--9, die cut matrix 10.

Coaxially to the punch 79, the clamping set is 1-pinner 11-13, spring-loaded relative to the punch holders 4-6 with the help of springs 14-16.

In the lower section-shge 3, the matrix-holders 17-19 of the first and subsequent transitions with exhaust matrices 20-22 of the penetration punch 23 in the last section, ejector members 24-26, spring-loaded with the weight of springs 27-29, are fixed. Nuanson holders 5 and 6 of the subsequent transitions are provided with windows 30 and 31 for placing the grippers 32 and 33 in them, secured to the frame 34 connected to the arm 35 of the robot 36 (workpiece feeder), measured in the vertical and horizontal directions.

In the section of the first transition, the first transition of the workpiece 37 is carried out, in the second section the extraction of the blanks 38, in the third section of the transition and the punching of the part 39.

The complex works in the following way. In the initial position, with the strain open, the robot using the gripper 32 through the windows 30 and 31 by horizontally moving the arm 35 delivers the raw workpiece to the matrix 20 of the first transition. Then, the robot arm 35, together with the frame 34 and the grips 32 and 33, is led out of the 1 gramme space. At the first working stroke of the press, the preform 37 of the first transition is stretched. Next

By moving the robot arm 35 with the gripper 32, the workpiece is withdrawn from the 1ptamp space, the arm 35 is lowered and re-inserted into the P1tamp. Key 38 is set on a second transition matrix 21. Horizontal, vertical and again horizontal movement of the arm 35 s helped 11) gripping 32 flat billet load; ... mc section of the first transition.

Then, the arm 35 of the robot with grippers 32 and 33 returns to its original position and a second stroke is made, at which the blanks 37 and 38 of the first and second-o transitions are stretched. Then, horizontally moving the arm 35 of the robot to the H1 tamper space is reversely inevitable; After this, by analogous non-interferences, as in the case of a nerve stroke, the robot loads a section of the first transition with a flat billet and the robot arm 35 is led out of the die space. In the third press run, the blanks 37 and 38 of the first and second transitions are pulled out simultaneously, and the part 39 is stretched and punched.

During the return stroke of the slider, the blanks 37 and 38, as well as the part 38, are pushed out of the cavity of the dies 20-22 by the ejector 24-26.

From the working area of the last section, the part and waste during the punching of the hole in its bottom can be removed, for example, by blowing.

If necessary, can be carried out cutting of the workpiece along the contour in the matrix 10.

To immobilize the robot arm and transmit the productivity, the area of the nerve section of the device can be equipped with a separate device for feeding p and youth workpieces into the working area of the first section, for example, a gate valve or another robot installed on the side of the nerve section of the poaps and dies.

The proposed device makes it possible to increase the productivity of the rig. This is due to the fact that it is possible to carry out 1 stamping of successive transitions in multi-stamp dies, the unloading and loading of which are carried out in parallel by one robot.
