Abstract

Use: for stamping products in automatic lines and flexible production lines. SUMMARY OF THE INVENTION: The punch is made with a wedge surface and samples on a lateral idle surface from the side of the removal position. At this position on the rails, a restrictive bar is installed. 5 ill.

Description

The invention relates to the processing of metals by pressure, in particular to dies for U-shaped bending, and is intended for use in flexible production modules and automatic lines.

The aim of H3o6peteHHfl is to increase the level of mechanization by improving the conditions for removing products. Its use simplifies the system of supply and removal of the product, making it more compact and reliable.

The goal has been achieved in that in a U-shaped bending die of piece blanks containing work tools, a working position and a removal position, guide bars and a wedge surface for moving the product; the wedge surface is made on the lateral non-working face of the punch from the side of the removal position, on the ribs between the said face and the working faces, samples are made for the ends of the shelves of the product, and the guide strips are made in length corresponding to the length of the bottom plate, and are equipped with a restrictive bar at the removal position .

Not shown is a stamp for a U-shaped bending with the proposed device, including its general view in section AA of FIG. 4, incl. at the beginning of the working stroke (Fig. 1), at the time of bending operations (Fig. 2), and at the end of the working stroke (Fig. 3). Furthermore, in FIG. 4 shows a plan of the bottom of the stamp, and in FIG. 5 is a section BB in FIG. 4.

A die 2 with an ejector 3 is placed on the bottom plate 1. A punch 5 with a wedge surface B and selections D is fixed on the top plate 4. The guides used to move the blanks and stamped products are strips b mounted on the lower half of the die. A transverse bar 7 is attached to the guide bars and is inserted into the structure in order to maintain a stable movement of the products along them.

The removal of the stamped article 8 from the working area of the press is carried out as follows. After it is brought out by the ejector 3 to the surface of the matrix 2, a workpiece 9 is fed into the working area, forcing it out of the working position and taking its place. Final conclusion

products from the working area are produced during the working stroke by the punch 5, interacting with the wedge surface B and displacing it further along the strips 6.

As a result of the working stroke, a product is created from the workpiece 9, which, after lifting it to the matrix surface, is in turn displaced from the working area by the subsequent workpiece and moves the product 8 further along the grooves by one more step, occupying its position. As new products are manufactured, they are gradually withdrawn from the stamp and transferred to the next processing position.
