Description

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting lengthy material into dimensional workpieces.

The purpose of the invention is to reduce the size of the device for dimensional cutting of long materials and to increase the cutting accuracy.

FIG. 1 shows schematically a device for measuring cutting of lengthy materials, of general type; in fig. 2 is the same cross section.

A device for dimensional cutting of lengthy materials contains a reducer 1, on which low-speed shaft a disk 2 is fixed and with the possibility of turning it off.

rum 26, made in the form of a roller for interacting with the retainer. 21 (hereinafter, the anvil 26 will be referred to as a "movable anvil). The bed 8 serves to fasten all the components of the device.

The device for dimensional cutting works as follows.

The tube 5 to be cut is inserted between the pull drum 3 and the pressure roller 6 and then into the hole of the fixed knife 9. The measuring disk 24 is set to a predetermined length by turning it about its axis. When the drive is turned on, the latch 21 holding the pawl 16 in the upper position and moving together with the driving disk 2, jumps onto the dvigate 3, which is one of the rest stop 26 and resets the pawl 16, which gives the rollers. On the drum 3 there is a torus under the action of the spring 27 enters into

brake 4 and gear 5, designed to transmit torque from gearbox 1. A feed roller 6, which is mounted on lever 7, mounted on frame 8, interacts with drum 3. At station 8, a fixed blade 9 is installed at the level of the pull drum 3, made in the form of a sleeve with a calibrated hole. The movable knife 10 is fixed on one end of the rod 11, moving 25 in the guides 12, the other end of the rod has a pin 13. The knife idling is provided by the spring 14. The drive disk 2, in cooperation with the wheel 5, is driving the driving drum 3, and the tube 15 being cut into measured lengths is carried out. The drive disk 2 interacts with the gear wheel 5 with a pawl 16, hinged on the protrusion 17 of the disk 2. The dog 16 is made in the form of a double arm, one arm of which is a tooth 18, interaction moving with the gear wheel 5, and the second shoulder has a roller 19 for interacting with a fixed stop 20 fixed on the frame 8 and serving to start idling the pull drum 3. 40 The drive disk 2 is also equipped with a spring-loaded lock 21, interacting with the protrusion 22 of the pawl 16 to keep it idle. The cam disk 2 also has a cam 23, which interacts with the heel 13 of the blade of the sliding knife 10 and serves to drive it. Measuring disk 24 is installed on the seat, made coaxially to the shaft of the gearbox, on the frame 8 and has the ability to rotate around an axis. The measuring disk 24 has a scraper 25 with clamping screws for fixing in a fixed position and an attachment with the wheel 5. At that, the pulling drum 3 snaps, feeding the tube 15. The feeding stops after the 2Q roller 19 of the pawl 16 touches the fixed stop 20 and outputs The doggie 16 is engaged with the gear wheel 5. In this position, the doggie 16 is fixed by a latch 21. With further rotation of the drive disk 2, its cam 23 naps onto the heel 13 of the knife 10, which, while moving in the direction of the two, cuts off the tube 15. Tube length full is between feeds.

Invention Formula A device for dimensional cutting of lengthy materials, comprising a base, with a water shaft, a feed mechanism made in the form of a pair of rollers, a mechanism for switching on and off the material feed and a cutting mechanism, including movable and fixed blades, characterized in that in order to reduce overall dimensions and increase precision cutting, it is equipped with a disk mounted on the drive shaft, a gear wheel mounted on one of the rollers of the feed mechanism, the mechanism for switching on and off the material feed is made in the form of two shoulders a hinged arm mounted on a disk of a tooth made on one shoulder of a two-armed lever with the ability to interact with a gear wheel, and an emphasis fixed on the base with the possibility of interaction with the other shoulder of a two-armed lever; moving knife. 0 rum 26, made in the form of a roller for interacting with the retainer. 21 (hereinafter, the anvil 26 will be referred to as a "movable anvil). The bed 8 serves to fasten all the components of the device. The device for dimensional cutting works as follows. The tube 5 to be cut is inserted between the pull drum 3 and the pressure roller 6 and then into the hole of the fixed knife 9. The measuring disk 24 is set to a predetermined length by turning it about its axis. When the drive is turned on, the latch 21 holding the pawl 16 in the upper position and moving together with the driving disk 2, jumps onto the movable stop 26 and resets the pawl 16, which, under the action of the spring 27, enters the stop 26 and resets the pawl 16, which under the action of the spring 27 enters the clutch with the wheel 5. In this case, the driving drum 3 vpphaet, making the feed tube 15. The feed stops after the roller 19 of the dog 16 touches the fixed stop 20 and removes the dog 16 from engagement with the toothed wheel 5. In this position, the dog 16 is locked with a lock 21. With further rotation of the drive disc 2, its cam 23 hits the pin 13 of the knife 10, which at the same time, moving in direction 12, cuts off the tube 15. The tube is cut in the interval between feeds.
