Description

The invention relates to metal working, and can be used to process lengthy workpieces, such as thin-walled tubes made from aluminum alloys and non-ferrous metals, usually obtained by pressing with a large curvature.

The purpose of the invention is to expand the technological capabilities of the device by supplying it with a continuously acting brake of the rotary disks and making a drive conveyor for the single-piece supply of blanks in the form of parallel scraper conveyors.

FIG. 1 shows schematically the proposed device, a plan (section A-A in FIG. 2); in fig. 2 shows a section BB in FIG. one; in fig. 3 shows a section B-B in FIG. 2, in FIG. k is a section of GGD in FIG. one,

A device for processing long workpieces is installed next to a press 1. The device includes a drive conveyor 2 for a piece feed of workpieces on which a deflecting stop 3 and a limit switch 4 are installed. The conveyor 2 is made in the form of at least two scraper conveyors 5 c. bodies 6 and loading and unloading zones located above the rotary disks fixed on the shaft 8 with the possibility of interaction of the projections 9 of the disks 7 with the pusher bodies 6 of the conveyor 5, at the end of which the 10 less than two for simultaneous cutting of products. Behind the saws, a discharge conveyor 11 with a straightening machine 12, a receiving belt 13 and a magazine 14 for parts are located in the technological sequence.

On the brackets 20 with the leading drive sprockets 17 of both scraper conveyors 5 in the bearings, the drive shaft 21 is mounted with circular saws 10 rigidly fixed on it 10. The drive shaft 21 is made of two parts (not shown) interconnected by splined or keyway connections with the ability to move one part relative to another when setting up. The rotation from the actuator 22 through the belt drive 23 is transmitted to the drive shaft 15 of the scraper conveyors 5, and from there through the gear gears 24 and 25 to the drive shaft 21, with the saws 10.

One of the rotary disks 7 is fixed rigidly on the shaft 8 mounted in bearings, and the other is movably on the shaft 8 with the ability to move along its axis along with the bracket 26. A brake 27 is mounted on the shaft, for example tape, with adjustable braking force depending on rigidity processed products.

The arms of the movable section of the scraper conveyor are attached to the upper part of the frame 28 of the mobile device, for example, using a dovetail, and the bracket 26 of the movable section of the drum — the stop is attached to the lower part of the bed as well.

The drive conveyor is provided with a chute 29 for blanks with skim 30. The adjustable spring-loaded elements are hinged on the axis 31 above the chute 29. The necessary gap between them and the gutter is established depending on the diameter of the products being machined. Speed of scraper Scraper conveyors 5 have leading conveyors 5 and sorting machine 15 and driven 16 shafts, on which leading 17 and driven 18 sprockets of scraper conveyors are mounted by means of a movable connection, such as splined or keyway, with the possibility of moving along their axes product size. The sprockets 17 and 18 are mounted in pairs on the respective shafts at some distance from one another and interconnected by flexible traction branches 19, which are attached.

12 is adapted to the speed of operation of the press by known means, for example, by means of an electromagnetic clutch, which receives a command to turn on from the end switch.

The device works as follows.

The workpiece 32 is driven by a conveyor: 2 is moved to the deflecting stop 3 and, through the limit switch 4, gives an electrical impulse to turn on the scraper conveyor 5.

Coaxially moving pushing bodies 6 of both scraper conveyors 5 simultaneously grip the workpiece 32 and move it along the chute 29 to the rotary disks 7, which are under the effect of a certain braking force generated by the brake 27. The workpiece being moved by the pushing bodies 6, is in the gap between the chute 29 and the spring-loaded elements And, pressed by the pushing bodies 6 to the protrusions 9 of the disks 7, rotate until straightness due to elastic deformation and then rotates the disk 7 until the workpiece 32 comes out reacting pushing of the scraper bodies 6 konveye- IpoB 5.

At the same time, when turning the discs 7 pressed against its protrusions 9, the workpiece 32 is encountered with the fast-rotating disks of the saw disks 10, 5 ends are cut. Upon further rotation of the discs 7, the projections 9 of the vehicle exits from under the workpiece 32, and the product over the slings 30 moves to the discharge conveyor 11 and is transported to the straightening zone of the sorting machine 12. The straightened product 32 falls on the inclined slide 13 and rolls into the store 14, the cycle repeats.

The invention allows pressing, cutting and dressing products and combining the operations of moving the blanks with their clamping, pre-dressing and cutting.
