Description

The invention relates to technological equipment for cold stamping and can be used in the field of engineering, in particular in the manufacture of a U-shaped front panel of the door of a home refrigerator.

A known installation for processing U-shaped products from a sheet by serial stamping, containing guides installed on the bottom plate, a punch, drowning stops and two temporary drowning stops, as well as cutting punches mounted on the upper plate for cutting technological cuts-bevels at the end of the sheet and bending punches (see patent RU 2510734, IPC B21D 22/02, published on 04/10/2014) - prototype.

A disadvantage of the known installation is that when processing products of reduced stiffness from thin-sheet material of significant dimensions in width, technological cuts-bevels on the end edges of the material, abutting against temporary sinking stops, do not center the material relative to the bending punches, especially when the front end of the material is not perpendicular, which complicates the design and reduces the quality of products, as well as the inability to produce products of U-shaped products with the edges bent inward.

The technical result of the utility model is aimed at simplifying the design of the installation, improving the quality of products and expanding the technological capabilities of the installation.

The technical result is ensured by the fact that the installation for the manufacture of U-shaped products by stamping from a sheet, containing guides sequentially installed on the bottom plate, drowning stops, as well as two temporary drowning stops, and cutting and bending punches mounted on the top plate, unlike the prototype, die cut punches are placed on the top plate along the axis of the sheet stock, at a distance equal to the length of the workpiece, while die cut punches and cut-outs of the workpiece are V-shaped and interact with temporary drown with support stops located on the bottom plate at a distance of the length of the workpiece, at both ends, which fix and center it parallel to the bending punches, while matrices are installed under the bending punches on the bottom plate.

The signs of the utility model meet paragraph 36 of the "Requirements for the application documents for the grant of a patent for a utility model", approved by order of the Ministry of Economic Development of the Russian Federation dated September 30, 2015 No. 701:

- “punching punches are placed on the top plate along the axis of the sheet stock at a distance equal to the length of the workpiece” - the presence of several parts (parts ...) interconnected ... providing structural unity and implementation of the device for general functional purpose (simplifying the design of the device);

- “at the same time, the cutting punches and cut-outs of the workpiece are V-shaped and interact with drowning stops located on the bottom plate at a distance from the length of the workpiece, at both ends that fix and center it parallel to the bending punches, while matrices are installed under the bending punches "- constructive implementation of parts of the device (parts ...); characterized by the presence and functional purpose of the parts of the device, their relative position (improves product quality).

The above mentioned essential features together prove their cause-effect relationship with the achieved technical result - simplification of the device design, improving the quality of the product and expanding the technological capabilities of the installation.

In FIG. 1 shows an installation for the manufacture of U-shaped products by stamping from a sheet; in FIG. 2 - the same, plan view, without the top plate; in FIG. 3 is the same, section AA, in FIG. one; in FIG. 4 is the same, section BB in front of the 1st flexible, in FIG. one; in FIG. 5 - the same, at the moment of the beginning of the 1st bending; in FIG. 6 - the same, at the end of the 1st bending; in FIG. 7 is the same, section BB in front of the 2nd flexible in FIG. one; in FIG. 8 - the same, at the beginning of the 2nd bending; in FIG. 9 - the same, at the end of the 2nd bending; in FIG. 10 shows the finished product.

The installation contains sequentially mounted on the bottom plate 1 on each side relative to the direction of movement of the workpiece 2 guides 3 and drowning stops 4, as well as two temporary drowning stops 5 at the bending positions.

On the top plate 6, die-cutting 7 and pairwise bending punches 8 with clamps 9 and underneath the die 10 are also installed sequentially in pairs at the position of the second bending; bending punches 11 with clamps 12 and also underneath the matrix are also placed in pairs at the position of the second bending 13. Cutting punches 7 are placed on the top plate 6 along the axis of the direction of movement of the processed sheet stock 2 at a distance equal to the length of the workpiece 2, bending punches and clamps are located on both sides along the length of the workpiece, both at the 1st bending position and at the position 2nd are flexible.

Installation works as follows.

Billet 2 by a conveyor (not shown) along the lower plate 1 is fed the cutting position between the guides 3 to the drowning stops 4, and when moving down the upper plate 6, the cutting punches 7 are axially cut at the ends of the sheet billet 2 to cut V-shaped cutouts. With further movement of the workpiece 2 to the position of the 1st bending, it is centered along the V-shaped cuts at the temporary drowning stops 5, is based on the matrices 10, and when the clamps 9 and the bending punches 8 are moved down, the first bending is performed. Then, the workpiece 2 is transferred to the position of the 2nd bending, where it is also centered along the V-shaped cuts by the temporary drowning stops 5, is based on the matrices 13, and when the clamps 12 and the bending punches 11 are moved down, the second final bending of the sides of the workpiece is performed.

After processing, the upper plate 6 with bending punches and clamps moves up and the finished part is conveyed (not shown) with recessed temporary stops 5 is transferred to the next processing.

The utility model "Installation for the manufacture of U-shaped products by stamping from a sheet" is industrially applicable.

At JSC "Production Association" Plant named after Sergo "developed design documentation, made the installation and is used in production.
