Definitions

the invention relates to a bending press for bending a sheet in the manufacture of a tube from the sheet metal, with which the sheet extending along a longitudinal axis is bent in at least one side region, wherein the bending press has at least one two-part bending tool, the at least one force generating element in operative connection stands, and wherein the force acting between the two parts of the bending tool and generated by the force generating element is transmitted via at least one tie rod.
a tubular body is formed from a metal sheet in a first step. This is then welded in a second step to the resulting seam of the colliding lateral ends of the sheet. As part of the first-mentioned process step, the lateral edge areas of the metal sheet are bent. For this purpose, bending presses are known.
the invention is therefore an object of the invention to provide a clinching press of the type mentioned above, which allows an improved bending of the sheet for a pipe in the sense of the desired goal, with only minor movements of the machine parts must be accepted and in particular only small deformations of the machine in Business. It should be possible to adjust the width of the sheet to be machined an improved power flow in the Anbiegepresse with adjustability.
the bending tool together with the force-generating element and tie rods is arranged transversely to the longitudinal axis of the sheet on at least one transverse to the longitudinal axis extending carrier slidably and clamped.
At least two bending tools including force-generating elements and tie rods are provided, which can be arranged symmetrically to a center plane.
the carrier preferably consists of an upper beam and a lower beam, which are arranged aligned with each other.
at least one centering element may be present with which the upper beam can be aligned with the lower beam.
a translational displacement element in particular a threaded spindle nut element, is provided, with which the unit consisting of bending tool, force-generating element and tie rod is displaced transversely to the longitudinal axis on the support, d. H. can be pushed into the desired position.
a further embodiment provides that preferably in one end region of the tie rod, a tensioning element is arranged, with which the tie rod can be clamped to the carrier.
the clamping element is preferably designed as a hydraulic piston-cylinder system.
two units consisting of bending tool, force generating element and tie rods on a support consisting of upper beam and lower beam in the tensioned state of the tie rods with the carrier form a frictionally closed frame. This advantageously prevents a pitching of the two tools relative to each other.
a plurality of units consisting of two bending tools, two force-generating elements, two tie rods and a carrier consisting of upper beam and lower beam in the direction of the longitudinal axis are arranged one behind the other.
the multiple units be interconnected by means of at least one extending in the direction of the longitudinal axis cross member.
a preferred embodiment provides that at least one tie rod, a carrier and a cross member are clamped together with a clamping element.
a relative pitching movement between the individual presses can be prevented, since the machine concept shuts off when used as intended on a closed frame. Since the tie rod to transfer the tool forces is always in the immediate vicinity of the place where the processing forces (bending forces) act, the deformations of the machine - compared to prior art solutions - can be kept low; the tool, d. H. the point where the force is generated is always near the tie rods.
the frame construction is used, with a dimensional change (i.e., when changing the width of the sheet to be bent) the tie rods are moved with the tool-cylinder unit, whereby the tie rods are always arranged directly on the introduction of force.
the tensioning of the tie rods is preferably carried out via hydraulically operated clamping nuts.
the pressure in the clamping nut is permanently present or that the tensioned state is maintained by removing or enclosing intermediate plates when the pressure is released from the clamping nut.
the tie rods are relaxed.
clamping nuts of the tie rods are permanently loaded with hydraulic oil, it is possible to measure the oil pressure and thus also to monitor the prestressing of the tie rods.
the proposed concept has the advantage that the tie rods are always in the vicinity of the tools (ie at the point of introduction of the force). This means a short power flow.
the deformation of the frame has only a very small influence on the bending of the sheet.
the tie rods are first released (relaxed) and then moved to the new position for optimum bending of the sheet transverse to the longitudinal axis of the sheet. In this position, the tie rod is clamped again with the clamping element, which is designed for this purpose as a quick-release device.
an Anbiegepresse 1 is shown, with a to be molded to a tubular body, flat sheet 2 (s. Fig. 1 ) should be bent in its side areas 3.
the bending press 1 For bending the side regions 3 of the sheet 2, the bending press 1 has two bending tools 4 (or a number of bending tools 4 consecutively in the direction of the longitudinal axis L). Each bending tool has two cooperating tool parts 4a and 4b. For bending the sheet 2, the two parts 4a, 4b of the bending tool 4 are pressed together, located between them sheet 2.
the required tool force is generated by a force generating element 5, which is typically formed as a hydraulic piston-cylinder element.
the transmission of the force of the force-generating element 5 by a tie rod 6, which extends vertically through the Anbiegepresse.
the unit consisting of bending tool 4, force generating element 5 and tie rod 6 is arranged in the direction Q transversely to the longitudinal axis L slidably on a support 7, which consists of an upper beam 7a and a lower beam 7b.
the beams 7a, 7b are essentially carriers with a relatively small thickness (in the direction of the longitudinal axis L), but with a relatively large (vertically measured) height, so that high bending moments can be absorbed with little deformation.
the exact positioning of the upper beam 7a to the lower beam 7b is effected by centering elements. 9
the unit consisting of bending tool 4, force generating element 5 and tie rod 6 can be clamped with a clamping element 11 with the carrier 7.
the clamping element 11 is designed as a hydraulic quick-clamping system.
the clamping elements 11 are, as the detail view according to Fig. 3 shows, as systems formed with a cylinder 13 in which a piston 14 is arranged. Thus, a hydraulic clamping force can be exerted on the tie rod 6.
the units consisting of bending tool 4, force generating element 5 and tie rod 6 can be arranged symmetrically to a center plane 8 in order to simultaneously bend the two side portions 3 of the sheet can.
Fig. 2 As in Fig. 2 As can be seen, several of the described units can be arranged on a plurality of carriers 7 which follow one another in the direction of the longitudinal axis L.
the composite of the individual units takes place by means of cross members 12, which extend in the direction of the longitudinal axis L.
the clamping elements 11 are relaxed, so that the frictional bond between tie rods 6, carrier. 7 and cross member 12 is solved. Then, by means of spindle-nut elements 10, which act as linear displacement elements, the units consisting of bending tool 4, force generating element 5 and tie rods 6 in the direction Q symmetrical to the center plane 8 (steplessly) moved until they are in the desired position. Thereafter, the clamping elements 11 are actuated again and thus the frictional composite of the components restored. The result is a stable frame construction, which can absorb the workers of the tools with little deformation.
