Description

The invention relates to the processing of metals by pressure and can be used to process long materials. .

The aim of the invention is to increase reliability in operation.

FIG. 1 shows the proposed device, the cut; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a kinematic diagram of a press; Haj FIG. 5 is a kinematic diagram of a slider drive; in fig. 6 is a sectional view BB in FIG. one.

The device comprises lower 1 and upper 2 pressing feed rollers 2, drive 3 roller 2 with fastening 4 for mounting it on a base (not shown). Behind the processing area in the course of feeding a lengthy material, in particular bar 5, there is an adjustable stop 6, and a slider 7 is located in the treatment zone. Slider 1 has a sleeve 8 on the first transition, which is spring-loaded and is coaxial with it. spring 10. Adjustable stop 6 is installed behind the zone of material processing on

bracket 11, in the guides of which a shaped wedge 12 is installed with a straight or curvilinear working surface on it, connected by means of a rod 13 to a moving actuator 14 rigidly fixed by means of brackets 15 on the bracket 16, which is rigidly fixed on the bracket 11 with screws (indicated by axial lines). The bracket 11 is placed on the base (not shown). In front of the rollers 1 and 2, in the course of feeding the bar 5, a material presence sensor 17 is installed. The actuator 3 is fixed on the housing 18 carrying the rail 19. In the rail 19 moves a slider mounted in the shape of a cup 20. closed by a cap 21, and inserts 22 installed in the glass 20. In the bottom of the glass 20, bearings 23 are installed and the nut 24 is threaded, into which the lead screw 25 is screwed. On the nut 24 there is a bevel gear 26 which engages with the bevel gear 27 fixed on roller 2, On cover 21 with adjusting screw 28 and nut 29 cm ntirovan off switch 30. The knife 7 is moved in the matrix block 31 of the press. The matrix unit 31 consists of a cut-off 32, upstream 33 and shape-forming 34 matrices. The stop 6 moves from the screw 35. On the slider 36, the punches 37 are fixed. The slider 36 is driven from the drive crank shaft 38 connected through pu 39 to the shaft 40 of the pushing mechanism through the sending device 41 with the shafts 42 of the rollers 1 and 2. The shaft 38 is connected via a transmission mechanism 43 with a portable device 44. From the shaft 40, through the cam 45 and the spring, a reciprocating movement is communicated to the cutting knife. In the matrix unit 31, an inclined slot 46 is provided with a branch channel 47. In FIG. 6 are indicated: L is the length of the end segment at the moment when the sensor 17 is turned on; I is the stroke length of the spindle 25 until the actuator 3 is turned on; And - the stroke length of the lead screw 25, is proportional to the sum of the time of submission of the cut-off workpiece, cut off and transfer it from the cutting matrix to the landing matrix of the first transition.

The device works as follows.

Rollers 1 and 2 feed the bar 5 into the cutting sleeve 8. The slide 7 cuts the sleeve 8 with the blank 49 by means of the die 32 from the bar 5 and transfers it into the matrix 33. The sensor 17 slides along the bar 5. When fed by the feed rollers 1 and, 2 the bar 5, when the length of its end section is equal to or less than the distance between the sensor 17 and the punch 9, which abuts against the adjustable stop 6, the sensor 17 activates the actuator 3, which pushes through the cover 21 the cup 20 and the running nut 24, as well as the bevel gear 26 to meshing with the bevel gear 27 of the feed roller 2. Rotation under through the bevel gear 26 is transmitted to the nut 24, which converts it into translational motion of the lead screw 25, which along the guides to the bushings 22 moves inside the cup 20 and after passing the path of length I, which is proportional to the length L of the bar 43, equal to the total length complete blanks, cut by the knife 7 from the end section of length L, includes the first contact of the on-off switch 30, which is connected to the drive 14. The drive 14 through the rod 13 moves in the guides of the bracket 11 a figure wedge 1 2 so that it is placed in position in the bracket 11 in the path of movement

head punch 9 (in Fig. 4 shown by the dotted line). At this moment, the slider 7 moves the unmeasured workpiece 49 consisting of two ends of the rods 5 and 48. At this, the head of the punch 9 slides along the working surface of the wedge 12 and, compressing the spring 10, pushes the ends 49 of the cutting sleeve 8 into the slot of the matrix unit 31 ( in Fig. 3 is shown by the dotted line, which of the matrix block

31 are removed under the influence of their own weight through the bypass channel 47. During the feeding of the rod 5 to the punch 9, cutting and transferring the unmeasured workpiece 49 to the matrix 33, the lead screw 25 passes the distance ii

and turns off the drive 3 at the second position of the switch 30. The bevel gear 26 disengages from the bevel gear 27, and in the drive 14 turns on the return stroke of the rod 13, under the influence of

which the wedge 12 occupies the original position.
