Изобретение относитс к обработке металлов давлением, в частности к устройствам дл гибки стержневых заготовок в замкнутые арматурные детали.The invention relates to the processing of metals by pressure, in particular, to devices for bending core blanks into closed reinforcing parts.

Известно устройство дл изготовлени замкнутых профилей из прутковых заготовок , содержащее подвижный шаблон дл навивки заготовок и механизм резки с поворотным ножом. На этом устройстве получают круглые детали - кольца 1.A device for making closed profiles from bar stock is known, comprising a movable template for winding blanks and a cutting mechanism with a rotary knife. On this device receive round parts - rings 1.

Цель изобретени - обеспечение возможности гибки деталей треугольной формы.The purpose of the invention is to provide the possibility of bending triangular shaped parts.

Поставленна цель достигаетс тем, что устройство, содержащее установленные на станине вращающийс шаблон и поворотный нож, закрепленный в корпусе, снабжено узлом формировани угловых зон заготовки, выполненным в виде роликов, св занных с приводом горизонтального перемещени , и узлом смещени готовых изделий вдоль щаблона , выполненным в виде плиты, установленной под углом к оси поворота щаблона и контактирующей с ее боковой поверхностью , корпус ножа расположен на одной горизонтальной оси с шаблоном и смонтирован с возможностью перемещени вдоль этой оси, а механизм поворота ножа выполнен в видеThe goal is achieved by the fact that the device containing a rotating template mounted on the frame and a rotary knife fixed in the housing is provided with a component forming corner areas of the workpiece made in the form of rollers connected with a horizontal displacement drive and a unit for displacing finished products along the template made in the form of a plate installed at an angle to the axis of rotation of the plate and in contact with its lateral surface, the knife body is located on the same horizontal axis with the template and mounted with the possibility of escheni along this axis of rotation and a knife mechanism is in the form

пальца, установленного на щаблоне параллельно его горизонтальной оси и взаимодействующего с ним упора, которым снабж|ен корпус ножа.a finger mounted on the template parallel to its horizontal axis and the support cooperating with it, which is provided with the knife body.

Claims

20 by an actuator 10 and has a pivoting frame 1 with roller cams 12 and an emphasis 13 for restricting the rotation of frame 11. A slider 14 is mounted in the guide 8, onto which a hinge 15 fixes a mechanism for cutting the blanks, made in the form of a housing 16, a replaceable knife 17 and a protrusion 18. The housing 16 with respect to the slider 14 is spring-loaded spring 19, and on the plablon 5 there is a grip 20 for periodically interacting with the protrusion 18. The guide 8 is mounted on the frame with the possibility of fixed movement along the movement of the slider 14 and has an eye 21 angles fastened therein, a two-armed lever 22 which with one arm associated with drive mounted on the frame 23 and the other by schatuna 24 - with the hinge 15 for guiding the movement of the workpiece on the machine frame is mounted the support roller 25. The device operates as follows. The end of the workpiece 7 is fixed on the template 5 and include the device. During the rotation of the template 5, the workpiece 7 is wound onto it. At a certain moment (see Fig. 2), the actuators 10 and 23 are turned on, as a result of which the roller cams 12 interact with the template 5, the workpiece rolls around the corner of the template 5, and the protrusion 18 of the cutting mechanism engages with the grip 20. With such a engagement, the body 16 rotates, as a result of which the knife 17 cuts into the workpiece with the point — the winding part of the workpiece is cut off from the original rod. After the cutting of the workpiece has been completed, the drive 23 is turned off, therefore, the lever 22 rotates to its original position, moving to the initial position the cutting mechanism of the workpiece. When this protrusion 18 leaves the engagement with the grip 20, and the spring 19 raises the housing to its original position. Then the next angle of the template 5 slides along the curved surface of the deflecting plate, which, pressing on the workpiece, displaces it along the template, as a result of which the cut part of the workpiece is dumped from the template 5, for example, into a container (not shown). Depending on the shape of the template, roller cams can be permanently attached to the template, and can also periodically interact with it. With continuous rotation of the template .5, a non-continuous formation of the bends of the workpiece is performed, and after each full rotation, the finished workpiece is cut off. Thus, the proposed device upon receipt of parts with corners, provides automatic operation, which improves performance. To rearrange the device to a different size, bend the blanks, template 5 is made removable, and guide 8, is adjustable. Claims An apparatus for making closed profiles from bar stock, comprising a rotating template mounted on a frame and a rotary knife fixed in a housing, characterized in that, in order to allow the bending of triangular-shaped parts, it is equipped with a corner forming unit of the workpiece. rollers associated with a horizontal displacement drive and a finished goods displacement unit along a template made in the form of a plate mounted at an angle to the axis of rotation of the template and contact Kqppus of the knife tapering with its lateral surface is located on the same horizontal axis with the template and is mounted with the possibility of moving along this axis, and the mechanism of the knife rotation is made in the form of a finger mounted on the template parallel to its horizontal axis and the stop interacting with it, provided with knife body.
