Description

The utility model relates to the processing of metals by pressure and is intended for use in the manufacture of parts U and L-shaped.

A known machine for bending valves, including a frame on which a drive and a plate with a bending device are installed, a casing is installed on the plate, having a flange for connection to exhaust ventilation [RU 44552 U1, B21D 11/12, B21D 7/022 publ. 03/27/2005].

A disadvantage of the known device is the complexity of its design, also the design of the device does not provide for bending parts of various profiles.

A device for bending rods into a clamp is known, comprising shafts mounted on the base with drive levers of the first and second bending transitions carrying rolling rollers, as well as a bending template and clamp, the bending template is made in the form of two sectors, one of which is mounted motionless on the base, and the other is mounted with the possibility of rotation relative to the shaft carrying the lever of the second transition of bending, each of the levers is made in the form of two pivotally connected links, while the link, external to the center of the template, bearing about a roller, mounted to swivel in the direction of the middle part of the template, the first bending lever is equipped with a fork mounted on its inner link with the ability to interact with fingers placed on the rotary sector [RU 2019336 C1, B21D 7/02 publ. September 15, 1994].

A disadvantage of the known device is that it does not allow bending of parts of various profiles.

The technical problem to be solved by the claimed utility model is the development of a universal design of the device for the manufacture of bent U and L-shaped products with flexible changeover of the device from one product form to another, simplification of the device design, unification of the main components of the device design.

The technical result of creating a utility model is to expand the functionality of the device.

The technical result is achieved in that a universal device for the manufacture of bent products contains a fixed support, an axis, a lever, a support plate, a bending template, a clamping means and a clamp. The clamp means is fixedly mounted on the base plate. The clamp is fixedly mounted on the lever, which is made with the possibility of rotation relative to the specified axis. The bending template is fixedly mounted on the base plate by means of fasteners.

There are options in which the bending template is a disk of a certain diameter for the manufacture of a U-shaped product or an overlay with certain sizes for bending L-shaped products with a small radius at an angle of 90 ° -110 °.

In FIG. 1 schematically presents the claimed device in axonometric projection.

In FIG. 2 and FIG. 3 schematically shows the steps for manufacturing a U-shaped article in axonometric projection.

In FIG. 4 schematically shows an embodiment of the manufacture of an L-shaped bent product in an axonometric projection.

Universal device for the manufacture of bent products (hereinafter referred to as the device) (Fig. 1) contains a fixed support 1, axis 2, lever 3, base plate 4, bending template 5, clamping means 6 and clamp 7.

In the fixed support 1 is made, for example, an installation protrusion of a square section (not indicated). The lever 3 is mounted on the axis 2, in which a groove is made (not indicated). A hole (not indicated) is made in the lever 3 for mounting the handle 8 in the form of, for example, a pipe or a rod of circular cross-section for rotation with respect to axis 2.

From above, the lever 3 is pressed against the base plate 4 by means of fasteners 9, for example, by screws. On top of the base plate 4 is fixed a bending template 5 by means of fasteners 10, for example, a bolt.

The bending template 5 may be a disk of a certain diameter for bending U-shaped products such as a clamp. There is an option in which the bending template 5 is a pad with specific dimensions for bending L-shaped products with a small radius at an angle of 90 ° -110 °.

The clamping means 6 is fixedly mounted on the base plate 4 by fixing the strap 11 with fasteners 12, for example, screws. The clamping means 6 is made in the form of an adjusting screw and a lining 13, which is installed on the side of the outer section of the bent product.

The clamp 7 is fixedly mounted on the lever 3 by means of the clamping plate 14 and the fastening connections 15. On the clamp 7, from the side of the outer portion of the bent product, a plate 16 is made of steel of increased hardness.

As fastening joints and elements, standard means are used, for example, bolted joints, screws.

For the manufacture of the proposed device using standard tools, technologies and materials.

The device works as follows.

The fixture assembly is installed in technological equipment, for example, an anvil in which a square hole is made, and in the fixed support 1 of the fixture, an installation protrusion of a square section (not indicated) is made.

The clamping means 6 and the lever 3 with the mounted clamp 7 in the initial position are rotated on one side relative to the bending template 5 (Fig. 2).

A workpiece, for example, a hairpin, a rod of a certain length, is clamped between the clamping means 6 and the bending template 5. When the lever 3 is in operation (Fig. 3, Fig. 4) by turning using the handle 8, relative to the vertical axis of the device, the clamp 7 forms the product from billets by rolling according to bending template 5.

Conversion of the device to various types of products is carried out by replacing one type of bending template 5 with another. For example, a disk of a certain diameter for bending U-shaped products, such as a clamp, is replaced by a pad with specific dimensions for bending L-shaped products with a small radius at an angle of 90 ° -110 °, for which fasteners are removed from the disk, then the plate is mounted and fixed by means of fasteners.

Thus, the claimed design of the device allows you to expand the functionality of the device by flexible readjustment of the device from one form of product to another, as well as reduce the number of manufactured equipment, increase the speed of release of finished products.
