Description

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting pipes.

The purpose of the invention is to expand the technological possibilities by ensuring the separation of non-dimensional residues from chips.

FIG. 1 shows an installation for cutting pipes, a general view; FIG. 2, section A-A in FIG. one; in fig. 3 - option to discharge the discharge tray when unloading short items into the pocket; in fig. 4 - the same, when cutting long products.

The pipe cutting machine consists of a cutting device 1, on both sides of which a roller table 2 with drive rollers 3 is located. In the openings of the roller table 2 after the cutting device 1, there are sledders 4 swinging from the pneumatic cylinder 5, parallel to the roller table 2, which, with a possibility of reciprocating movement from the actuator 7, is located a carriage 8 with an anvil 10 that is folded from the pneumatic cylinder 9. An anvil 11 located at an operating position along the axis of the cutting device 1 is fixed to the anvil 10.

In the opening of the roller table 2 behind the cutting device 1, an unloading chute 12 (FIG. 2) is placed, having a T-shape of different shape, with its base 13 being angled about to the horizontal plane, ensuring free sliding of the cut products. The side wall 14 of the tray has an angular cut-out for the passage of the stop with the pin 11 in the reclined position. The side wall of the tray 12 (FIG. 3 may be made of two parts 15 and 16 connected to each other by rails 17 and a freely rotating gear 18 for their synchronous movement from pneumatic cylinder 19 in opposite directions. Assembly pockets are installed parallel to it from side of the roller table 2 20 and 21 for receiving, respectively, short items unloaded from tray 12 and the length

nk discharged by means of jumpers 4 (Fig. 1). Under the cutting tool of the device 1 for cutting placed box 22 for collecting chips.

The operation of the pipe cutting unit depends on the design of the side wall 14 of the receiving tray and the length of the cut piece.

An embodiment of the one-piece side wall 14 (Fig. 2).

When cutting a lengthy product whose length exceeds the inception

Its known size, determined by the design of the receiving chute 12, the workpiece 23 is loaded onto the rollers 3 of the roller table 2 and is transported by the rollers through the cutting device 1 to the stop 10 installed from the cutting plane of the cutting device at a distance corresponding to the required size of the cut product 24. Then the workpiece 23 is clamped in the cutting device, and the product 24 is cut. Simultaneously with the clamping of the workpiece 23, the drive 7 is turned on and the carriage 8 with the stop 10 is retracted, the stop 10 is folded back, and the product 24 by the rollers 3 of the roller table 2 is moved to the area of the assembly pocket 21 and is dropped into it by means of the resetters 4.

In the case of cutting a short product, the workpiece 23 also moves to the stop 10, is clamped in the device for cutting, while the stop is not retracted, which excludes the possibility of moving the products 24 along the roller table.

The cut product 24 hangs on the pin 11. Then the stop 10 moves out with the pin 11 and the product 24 hanging on it, the carriage 8 is retracted, moving over the side wall of the receiving tray through the cutout made in it. When the carriage 8 moves, the pin 11 leaves the product, and the product held by the side wall moves from the pin, lowers onto the base 13 of the tray, 12, slides along it into the assembly pocket 20, and the carriage with the stop and pin returns to its initial position for receiving next product.

If the side wall of the receiving tray is divided vertically (Fig. 3), the work is carried out as follows.

When cutting lengthy products, the work is similar to making the side wall integral, with the difference that the parts 15 and 16 of the side wall of the tray are previously moved apart from the pneumatic cylinder 19 in order to skip the workpiece 23 until it stops 10.

When cutting a short product, the workpiece 23 moves to the stop 10, is clamped in the device for cutting, while the parts 15 and 16 of the side wall of the tray are shifted from the pneumatic cylinder 19, the stop 10 is not retracted, which eliminates movement of the product 24 along the roller table.

The cut product 24 hangs on the pin 11. The carriage 8, together with the stop and the pin, is retracted and the product is held up by the shifted portions 15 and 16 of the side wall, shifting 12714 seconds.

ten

from the pin and on the inclined base 13 slides into the assembly pocket 20. Then the carriage with the stop and the pin returns to its original position to receive the next product. In the process of cutting the workpiece 23, the chips fall into box 22 and are collected there.

Compared with the prior art, the invention allows for improved working conditions by ensuring separation of non-measuring residues from chips.
