Изобретение относитс к обработке металлов давлением и предназначено дл использовани на заводах железобетонных изделий.The invention relates to the processing of metals by pressure and is intended for use in factories of reinforced concrete products.

Известно устройство дл гибки монтажных петель, содержащее размещенные на столе пуансон, установленный с возможностью возвратно-поступательного перемещени посредством привода и взаимодействующий с опорными роликами горизонтальной гибки, а также шестерню, взаимодействующую с рейкой и несущую эксцентрично расположенные ролики, при этом шестерн смонтирована на каретке, перемeщae oй пуансоном 1 J.A device for flexible mounting loops is known, comprising a punch arranged on a table, mounted with the possibility of reciprocating movement by means of a drive and interacting with horizontal bending support rollers, as well as a gear that interacts with the rail and carrying eccentrically located rollers, while the gear is mounted on a carriage, move the punch 1 J.

Недостатком известного устройства вл етс его конструктивна сложность .A disadvantage of the known device is its structural complexity.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Поставленна цель достигаетс тем, что в устройстве дл гибки монтажных петель, содержащем размещенные на станине привод, узел горизонтальной гибки, выполненный в виде оправки и опорных вертикальных роликов , св занный с ползуном и узел вертикальной гибки,содержащий гибочный элемент« взаимодействующий с опорными горизонтальными роликами, узел вертикальной гибки выполнен в виде трехплечего поворотного рычага, одно The goal is achieved by the fact that in a device for flexible mounting loops containing a drive placed on a frame, a horizontal bending unit, made in the form of a mandrel and supporting vertical rollers, is connected with a slide and a vertical bending unit containing a bending element "cooperating with supporting horizontal rollers , the unit of vertical bending is made in the form of a three-arm swing arm, one

10 плечо которого св зано с приводом, гибочный элемент расположен на втором его плече, а ползун шарнирно св зан с третьим плечом, при этом оправка и опорные ролики узла горизон15 тальной гибки установлены с возможностью регулировочного перемещени , а опорные ролики узла вертикальной гибки размещены на станине.10 the shoulder of which is associated with the drive, the bending element is located on its second shoulder, and the slider is hingedly connected with the third shoulder, while the mandrel and the support rollers of the horizontal bending unit are installed with the possibility of adjustment movement, and the support rollers of the vertical bending unit are placed on the frame .

Claims

FIG. 1 shows the device, the initial position, a longitudinal section; in fig. 2 - the same, when performing a central bend, longitudinal. section, in fig. 3 is a view A of FIG. 1; in fig. - section bb in fig. 1. All units of the device are mounted on the frame 1. By means of the brackets a cylindrical rod 2 is fixed on the frame, along which the slide 3 moves, on the latter the adjustable central bending roller is installed. From the turn to the pin the roller is fixed by the slit of the table 5 in which it moves. Rods 6 are attached to the slider rods, by means of which the slider is pivotally connected to the shoulder of the three-arm lever 7, the second arm of which is connected to the pneumatic cylinder 8, and the third shoulder is made in the form of a punch 9, by means of which the ends of the workpiece are bent between the horizontal rollers 10, along the edges of the slot. The table 5 has adjustable support rollers 11. The finished product is thrown off. The triplex arm rotates on axis 13. The device operates as follows. The initial position of the bending mechanism is shown in FIG. 1 and 3. The slider 3 is in the extreme right position. The workpiece is inserted into the gap between the support rollers of the Pi roller k. When the rod of the pneumatic cylinder 8 is retracted, the lever 7 is rotated, and the rods 6 move the slider 3 to the extreme left position. The center bends the workpiece. In this case, the third lever arm, made in the form of a punch 9, occupies the upper position, and both ends of the cooking fall into the gap between the punch 9 and horizontal rollers 1. During the return stroke of the pneumatic cylinder, the piston rod extends and the three ends of the workpiece are bend. The punch 9 bends the ends of the workpiece between the horizontal rollers 10 and drops the product onto the clip, along which the finished product is withdrawn from the machine. By means of the rods 6, the slider is moved to the extreme right position, and the device is ready for the next cycle. The invention is a device for flexible mounting loops containing a drive mounted on a frame, a horizontal bending unit made in the form of a mandrel and supporting vertical pins connected to a slider, and a vertical bending unit containing a bending element cooperating with supporting horizontal rollers characterized in that, in order to simplify the construction, the vertical bending assembly is made in the form of a three-arm swing arm, one arm of which is connected to the drive, the bending element is located on its second arm, and lzun pivotally coupled to the third port, wherein the mandrel and the support rollers .gorizontalnoy bending assembly mounted for adjusting movement, a vertical support assembly bending rollers arranged on the frame.
