Description

II

Изобретение относитс к области машиностроени , а именно к конструкци м прессов дл гибки профилей.The invention relates to the field of engineering, namely to the design of presses for bending profiles.

Известен горизонтальный профилегибочный пресс с программным управлением, содержащий приемную и выходную опоры и расположенную между ними неподвижную опору, механизм подачи, а также устройство дл контрол координат конечных точек изгибаемого профил , включающее каретку с контрольным органом 1.A well-known horizontal programmable press with a programmed control, comprising a receiving and output support and a fixed support located between them, a feeding mechanism, as well as a device for controlling the coordinates of the end points of the bendable profile, including a carriage with a control body 1.

В известном устройстве процесс гибки каждого профил осуществл етс за 2-3 операции, а свободный контролируемый конец профил св зан с опорной тележкой, котора в свою очередь св зана с нижней портальной тележкой.In the known apparatus, the process of bending each profile is carried out in 2-3 operations, and the free controlled end of the profile is connected with the support carriage, which in turn is associated with the lower portal carriage.

Недостатком известного устройства вл етс низка производительность и недостаточна точность гибки, так как на конец профил воздействуют внешние силы от трени тележек в их направл ющих и на больщом удалении коррдинаты конца профил не определ ют его истинного положени изза гибкости профил .A disadvantage of the known device is low productivity and insufficient accuracy of bending, since external forces from the trolleys in their guides affect the end of the profile and, at a large distance, the end of the profile does not determine its true position because of the flexibility of the profile.

Цель изобретени - повышение производительности и точности получаемых на прессе изделий.The purpose of the invention is to increase the productivity and accuracy of the products obtained on the press.

В предложенном прессе указанна цель достигаетс за счет того, что он cнaбжeFl приводом каретки, устройство дл контрол координат конечных точек изгибаемого профил выполнено в виде консоли с направл ющими , каретка с контрольным органом смонтирована в упом нутых направл юших, при этом консоль шарнирно установлена на выходной подвижной опоре, а механизм подачи смонтирован с возможностью вращени на приемной подвижной опоре.In the proposed press, this goal is achieved due to the fact that it is equipped with a carriage drive, a device for controlling the coordinates of the end points of the bendable profile is made in the form of a console with guides, the carriage with a control body is mounted in the mentioned directions, and the console is hinged on the output the movable support, and the feed mechanism is rotatably mounted on the receiving movable support.

На фиг. 1 показана конструкци пресса , общий вид; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows a press structure, general view; in fig. 2 is a view A of FIG. one.

Claims

A profile-bending horizontal press with a software control system consists of two movable supports 1 and 2 and a fixed support 3 located between them. On the movable support 2, on the exit side of the workpiece, the console 4 of the control device is fixed so that it can be rotated to the required angle by means of a drive mechanism 5. The angle of rotation of the console controlled by the sensor 6. The center of rotation of the console is aligned with the vertical axis that intersects the calculated bending line that intersects the baseline 7 of the press in the initial position. The carriage 8 with the control body 9, which is a fixed contact stop, is placed on the guides of the console 4 below. The carriage using the actuator 10 has the ability to move along the console guides with the stop at the specified points controlled by the sensor. On the movable support 1, on the input side of the workpiece, a feed mechanism 11 is installed with a hydraulic grip strip 12. The feed mechanism is installed on the axial joint in the center of the support and can be rotated by the profile 13 along its axis. The size of the strip feed strip can be preset to the calculated feed rate for each profile size. The software control system of the press 14 is combined with a control panel. The press works as follows. Information about the shape of the strip, expressed by a consecutive number of coordinates of the end points of the profile, specified by the angle values and the distance for each section are flexible at a constant feed rate embedded in their calculation, encoded on a punched tape, is entered into a photo reader of a program management system. The press with the profile blank inserted is switched on from the control panel 14 into operation. A command is received to turn the console 4 to a predetermined angle and to move the carriage 8 with the control body 9 to the starting point. Then, the profile blank is clamped and flexible through the movement of the movable supports 1 and 2 of the press. The bending process continues until the end of the curved part of the profile comes into contact with the control body 9 of the carriage 8. At the moment of contact of the control body 9, the curved part of the profile receives a curvature corresponding to the calculated (within tolerances) and the bending process is terminated. Thereafter, the profile is released from the clamp and the movable supports 1 and 2 are retracted to a fixed value to provide the necessary clearance for longitudinal feed to the next step, after which the cycle is repeated the necessary number of times until the workpiece is bent. The invention includes a programmable horizontal press with a programmed control, comprising receiving and output subspecies and a fixed support located between them, a feeding mechanism, and a device for controlling the coordinates of the end points of a curved profile including a carriage with a control organ, characterized in that the purpose of increasing the productivity and accuracy of the products obtained on it, it is equipped with a carriage drive, a device for controlling the coordinates of the end points of the bent profile is made in the form of a console with guides, a carriage with a control body is mounted in the said guides, while the console is pivotally mounted on the output movable support, and the feed mechanism is mounted rotatably on the receiving movable support.
