Abstract

1. Способ эксплуатации устройства растяжения пластин для растяжения и правки катаной или кованой тянутой заготовки, в частности листов или пластин, в котором зажимная головка состоит из множества распределенных по ее рабочей ширине, расположенных рядом друг с другом перпендикулярно плоскости заготовки ламелей, которые на своей обращенной к рабочей зоне стороне выполнены с проходящим по всей ширине зажимной головки зажимным зевом, а на своей противоположной рабочей зоне стороне посредством натяжной системы притянуты к жесткому на изгиб коробу, отличающийся тем, что в зазор, возникающий между зажимной головкой (1) и гибочным коробом (9) в зависимости от прикладываемого при растяжении рабочего усилия, регулируемым образом вводят устанавливающееся автоматически и находящееся под постоянно действующим давлением натяжное средство (10). ! 2. Устройство для растяжения и правки катаной или кованой тянутой заготовки, в частности, листов или пластин, с зажимной головкой, состоящей из множества распределенных по ее рабочей ширине, расположенных рядом друг с другом перпендикулярно плоскости заготовки ламелей, которые на своей обращенной к рабочей зоне стороне выполнены с проходящим по всей ширине зажимной головки зажимным зевом, а на своей противоположной рабочей зоне стороне посредством натяжной системы притянуты к жесткому на изгиб коробу, в частности, для выполнения способа по п.1, отличающееся тем, что между зажимной головкой (1) и гибочным коробом (9) расположено клиновидное натяжное средство (10), находящееся под постоянно действующим давлением. ! 3. Устройство по п.2, отличающееся тем, что клиновидное натяжное средст�1. A method of operating a plate stretching device for stretching and straightening a rolled or forged drawn workpiece, in particular sheets or plates, in which the clamping head consists of a plurality of lamellas distributed along its working width, located next to each other perpendicular to the plane of the workpiece, which on their facing to the working area, the side is made with a clamping jaw extending across the entire width of the clamping head, and on its opposite working area side, by means of a tension system, they are drawn to a bending-rigid box, characterized in that it is in the gap that appears between the clamping head (1) and the bending box ( 9) depending on the operating force applied during stretching, a tensioning means (10) that is installed automatically and is under constant pressure is introduced in a controlled manner. ! 2. A device for stretching and straightening rolled or forged drawn workpieces, in particular sheets or plates, with a clamping head consisting of a plurality of lamellas distributed along its working width, located next to each other perpendicular to the plane of the workpiece, which, on their side facing the working area on the side are made with a clamping jaw extending across the entire width of the clamping head, and on its opposite working area the side is pulled to a bending-rigid box by means of a tension system, in particular to carry out the method according to claim 1, characterized in that between the clamping head (1) and the bending box (9) there is a wedge-shaped tensioning means (10), which is under constant pressure. ! 3. The device according to claim 2, characterized in that the wedge-shaped tensioning means

Claims

1. A method of operating a device for stretching plates for stretching and dressing a rolled or forged drawn preform, in particular sheets or plates, in which the clamping head consists of a plurality of lamellas distributed along its working width, located next to each other perpendicular to the plane of the workpiece, which are facing to the working area, the side is made with a clamping pharynx extending across the entire width of the clamping head, and on its opposite side to the working area, by means of a tensioning system, they are drawn to a rigid bend a duct, characterized in that in the gap arising between the clamping head (1) and the bending duct (9), depending on the applied working force, the tensioning means (10) is installed automatically and under constant pressure.

2. A device for stretching and straightening a rolled or forged drawn workpiece, in particular sheets or plates, with a clamping head consisting of a plurality of lamellas distributed along its working width, located next to each other perpendicular to the plane of the workpiece, which are on their facing the working area the side is made with a clamping pharynx extending across the entire width of the clamping head, and on its opposite working area, the side is pulled by means of a tensioning system to a box rigid to bending, in particular for performing the method according to claim 1, characterized in that between the clamping head (1) and the bending box (9) there is a wedge-shaped tensioning means (10), which is under constant pressure.

3. The device according to claim 2, characterized in that the wedge-shaped tensioning means (10) is equipped with a cylinder-piston block (11) acting as an adjusting means.

4. A device according to any one of claims 2 or 3, characterized in that each of the end walls (12) of the bending box (9) facing the clamping head (1) has a wedge surface (13) additional to the wedge-shaped tension means (10).
