Description

The invention relates to the processing of metals by pressure and can be used in mechanical engineering for cutting pipes into dimensional workpieces. The whole invention is to improve the service conditions of pipe cutting and to improve its reliability by pre-clamping pipes in the lower housing.

The hand wedge 43 contains inclined surfaces 51 and 52 and parallel to the new characteristics 53 and 54, interacting in correspondence with rollers 38 and 45. lia mobile; plate 1 is rigidly fixed with ha 55, which with its notch 56 interacts with a clamp 57 rigidly fastened in the upper housing 8. Guides 4i contain heads 58 that limit the movement of the slide 40. Stop 59, the same as the fixed one in crown 49, limits the stroke 47. In the sleeve x blades 15 and 16 are cut pipe 60. The pipe cutter works as follows. The initial position: movable top of the I and I with stop 4. Slider 40, th 55 and l, W1101 and Klino.m 43 are in the right position; 1st position. Between the surface of the roller 37 and the bottom surface of the i: OJi3yiia 40 is also a gap. Fork 32 „runs along the stand 21 on the stand, protrusions 18 and 20 and Kazy of the sleeve knives 15 and 16 are separated. The pipe 60 is inserted into the sleeve knives 15 and 16 and is fed up to the stop (not shown). The working stroke of the press slide is activated. When moving the upper nlita 1 airbag double-sided I11 k.shn 43 with its inclined nozzles 51 and 52, it interacts with the rollers 38 and 45, and the ha ha 55 frees the upper body 8 from the str. 57 grip, and , rotate around the clock axis around axis 7, 15 the upper body of the cylinder is fixed onto the pipe 60 with a knife 15. The pipe 60 is not yet clamped: there is still a gap between the support 4, but the blade 40 and the upper surface of the upper body 8 . 11ri; i-1 line-up of the bottom of the movable top plate I D-sided side of the 4, -) (non-inclined ove) hnost 51 n 52 1 press per pc, 38; 45, pushes them, respectively, in, left and viravo and In) D1gg, evoi) al; 1.

At the same time, the fork 31 moves down and to the left under the action of the axis 29 and, turning clockwise, slides along the bar 33 to the left and presses (presses) the protrusion 18. The bushing knife 15 clamps the pipe 60 in the upper housing 8. The gap between the stop 4 and the upper housing 8. .JiVl and. Further, during the movement of the movable upper plate 1 downward, an elastic element (for example, polyurethane) 39, deforming, finally presses the tube 60 with the stub knife 15 in the upper housing 8 (the force P of the crimping of the pipe 60 in the upper and lower casings 8 and 9 of the stub blades 15 and 16 is within aug: P; at. At the end of crimping the tube 60, the stop 4 touches the upper body 8, the deformation of the elastic element 39 (and the pipe clamp) stops and the pipe begins to cut. During the cutting process, the upper body 8 with the stub knife 15 rotates clockwise about axis 7 and fixed lower casing 9, cuts the workpiece from the pipe.At the same time, the rollers 38 and 45 are on parallel surfaces 53 and 54 of the wedge 43. Then the press slider together with the upper movable plate I, the weight 55, the stop 4 and the double-sided wedge 43 are raised upwards. ha 55 by grip 57 rotates the upper body 8 counterclockwise with respect to axis 7. The upper body 8 occupies its upper position, aligning the axis of the sleeve knife 15 with the axis of the sleeve knife 16 of the stationary body 9. The double-sided wedge 43, lifting up, comes out of contact with the rollers 38 and 45 and exempt from de the formation of the elastic element 42. The elastic element 39 in the upper plate 1 is also released from deformation. By day

Claims (1)

1. By the action of the elastic forces, the sleeve knives 15 and 16 open, freeing the pipe 60 and the cut piece. Next, the tube 60 is again fully fed, pushing the workpiece onto the discharge tray (not shown), and the cycle is repeated. Claims of punch cutting tube containing. ---- - --.-.....-, -I, - - J, - 1 movable and fixed plates, spring-loaded sliders mounted on each plate, upper and lower cases mounted by means of a common axis on a fixed plate The first of which is mounted on the axis is hinged and connected to the movable plate by means of tongs with a groove, sleeve knives mounted in cases and made with through radial grooves and protrusions, one of which in each knife is arranged to interact with the corresponding case other - with a corresponding spring-loaded crawl by means of a roller system located in a corresponding housing, characterized in that, in order to improve service conditions and increase reliability by providing a preliminary clamping of the pipe in the lower housing, it is provided with a roller pivotally mounted on a spring-loaded bottom plate slider and wedged on a movable plate with a double-sided wedge, each of the sides of which is formed by sections inclined to its longitudinal axis and parallel to it, and is located respectively with the possibility of Interaction of the roller lever system housed in the lower housing, and a spring-loaded slide with a roller fixed plate, wherein the lower housing rigidly .zakreplen on the fixed plate.
