Description

BASIC Auth. without .Y106938 describes a method of bending pipes on a pipe bending machine with a pressure roller moving in the direction perpendicular to the pipe feed, with rp and eI CHIM heating HDTV and cooling sections adjacent to the zone;

In the proposed device improved the specified method. It is attached to a hinge, sharkingly connected at one end with the end of the pipe being bent, and at the other end with the indicator arrow, inductively; Part 1 of the sensor: 1ka and so on. But short-axis around the axis, -disposed in the plane of the inductor of the HPSR in the direction of rotation curved part of the pipe.

In the drawing, the schemes are shown atopically;);

In the plane of the inductor / at a distance equal to the radius of the gpbc specified by the product's merchandise), a wall 2 device is installed that can be rotated in the pick-up (the bearing is not shown in the drawing). Plate 2 is associated with palik 2, in a sleeve of which

freely move the boom 4. End of its crepe with the straight end of the Tpy6b.j 5 in the middle of the bend umbrella in any place; npii pomopli bomutia b. The boom 4 can b1) 1 hardened sleeve 7. i; o1ts pa.tets, with poLu and whose boom 4 communicates with st. 8. 8. On the hinge 2 is attached the arrow 9, indicating the angle of the bend of the pipe on a scale plotted on 10. Yloc: i & 2, set at the required distance at the distance R from the middle of the pipe, and horses, rod 4 fixed at IOMOP1 and clamp 6 at the free end of pipe 5. arrows 8 and 9. in. Similar positions. Then include pipe bending

DOS n; m) goes through the zone of heating a, sezlyvaelplo and}; diktopo; /. and in each successively gets killed at the elementary angle. Prp this all points of the pipe, are located; H mS in front of the inductor /, must be circumferences,

concentric roller 2. If the bending radius is reduced, then the rod 4 moves relative to the plate 3 so that the arrow 8 is deflected in the direction indicated by the anak minus. With an increase in the radius r: -i6iiH, the arrow 8 deviates towards the enacc plus.

Rod 4, retracted together with the free end of the shaft, carries with it a plateau 5 and is attached to it. 2. The angle of rotation of the roller 2 can be measured according to the direction of the arrow 9 on the scale of the lanyard 10. Since the angle of rotation of the rod 4 equals the angle of the bend, then the arrow 9 shows at what angle the pipe is bent.

Thus, a flexible worker has a CUSTOM: To show anime arrows 8, to correct the position of a press roller, to achieve a bend with a given radius, and according to the indications of arrow 9, to follow Sia with a bend angle of the pipe and to turn off the machine in a timely manner, attaining the drawing size.

Mixing boom 4 relative to roller 2 or plateau 3. Can be fixed not only by the Mechanical .M indicator in arrows 8, but also by the end switches, as shown, by using them on board 3, or by an inductive sensor. The number 12 denotes guide rollers.

P 5 e d ete invented. And

Device for controlling the process of pipe bending on a pipe bending machine, according to the method according to the author. St. L1 106938, distinguished by .ee-with the use of the rod, which is pivotally connected with one end with a free end of a bent pipe and the second test pipe with, an arrow of the indicator, an inductive sensor, etc., rotatable around an axis located in the plane of an HDTV B torus center in the center of the curved part of the pipe.
