Definitions
- the invention relates to a flexible hold-down for a profiling system for clamping a sheet to be profiled during roll forming of cold or hot profiles with variable cross-section, an associated method and a product produced by this method according to the preamble of claim 1, claim 10 and claim 17th
- rolls acting together in pairs provide a profile in the form of which a sheet to be formed is brought.
- the forming of the sheet takes place in several stages with multiple roller pairs or roll stands.
- the stepwise degree of deformation of the sheet is chosen such that the sheet is not undesirable stressed and deformed.
- a similar device for producing profiled sheets with variable cross section is known from DE 10 2004 040 257 Al.
- the device has an additional roller and a support element, wherein the rollers and support elements of the mill stand to ensure that no inadmissible deformations occur on the sheet.
- the object of the present invention is to eliminate the above-mentioned disadvantages of the prior art with regard to the undesired deformations during flexible profiling and to provide a reshaped product with a continuously defined and controlled height of the bottom.
- This object is achieved by a flexible hold-down for a profiling system for clamping a sheet to be profiled during roll profiling of cold or hot profiles with variable cross section and an associated method according to the preambles of claim 1 and claim 11.
- Fig. 1 shows a side view of a flexible hold-down according to the present invention.
- Fig. 2 shows a perspective view of an upper assembly of the flexible blank holder of Fig. 1 with an adjustable upper jaw 2a with an adjustable clamping shoe 2b of the present invention.
- Fig. 3 shows a perspective view of a flexible hold-down according to the present invention, which is integrated in a profiling plant of the prior art.
- Fig. 1 shows a flexible blank holder 1 of the present invention for any profiling of the prior art.
- the hold-down 1 includes an upper assembly 2 and a lower assembly 3 which clamp a sheet 5 to be profiled therebetween.
- the two arrangements 2, 3 are via an upper guide 2 d and a lower guide 3d in a frame 4th movably mounted.
- the upper assembly 2 includes a bracket 2c and an adjustable upper jaw 2a with an adjustable clamping shoe 2b.
- the lower assembly 3 includes a holder 3c and an adjustable lower jaw 3a.
- the guides 2d, 3d may be configured as a rail guide. And in another embodiment, the guides 2d, 3d may be configured as a roller guide. And in another embodiment, the guides 2d, 3d may be configured as dovetail guides, prism guides, narrow guides or cylindrical guides.
- the configuration of the upper guide 2d can be different from that of the lower guide 3d.
- analogously to the upper clamping shoe it is also possible to provide a lower clamping shoe which can be functionally adapted like the upper clamping shoe.
- the adjustable upper jaw 2a can be advantageously pressed by a hydraulic leverage in a direction perpendicular to the sheet feed on the sheet to be profiled plate 5 and against the lower jaw 3a.
- only the jaw 2a is pressed against the sheet by means of a pneumatic or an electromagnetic leverage, the lower jaw 3a being adjustable by a screw to a predetermined height.
- the arrangements 2, 3 of the flexible blank holder 1 clamp the sheet on both sides from above and from below. In another embodiment, the arrangements 2, 3 clamping the sheet embracing on one or both legs 5a, 5b.
- the assemblies 2, 3 of the flexible Hold-down 1 in the frame 4 on the guides 2d, 3d passively with the sheet feed, ie without its own drive via motors, pulled along. As a result, no additional forces are introduced into the sheet during the profiling, so that a 100% match with the sheet feed is ensured.
- Fig. 2 shows an upper assembly 2 with an adjustable upper jaw 2a with an adjustable clamping shoe 2b of the present invention.
- means are used to adapt the clamping shoe 2b during the profiling process in the feed plane (plane xz) or perpendicular to the feed plane (y direction). These means fit the clamping shoe 2b in the width, height, shape or position of the profile of the sheet, since in three-dimensional cross-sections, d. H. with height-adjustable floor, the arrangement 2 must follow the bottom of the profile and must adjust in height and inclination. If the sheet is bent on different sides with respect to the ground, it would be conceivable that these means act on the corresponding sides of the floor. By this adaptation, a collision with the legs 5a, 5b is avoided and the sheet is not exposed to undesirable deformations.
- Fig. 3 shows a flexible downholder 1 according to the present invention, which is integrated in a profiling plant of the prior art.
- a method of profiling a sheet 5 using the flexible blank holder 1 includes the steps described below. Only one mill stand is shown in Figure 3, but it will be readily understood by those skilled in the art that there are further mill stands upstream and downstream of the mill stand which are part of a profiling line.
- step 1 the sheet 5 to be profiled is clamped.
- the two assemblies 2, 3 press out of a starting position (rest position) at a defined point the profile of the sheet.
- This predetermined location is determined in advance depending on the type of deformation and the sheet material used and the geometry of the rolling mill.
- the sheet is clamped on both sides from above and from below.
- the sheet can be clamped around one or both legs 5a, 5b.
- all degrees of freedom must be suppressed to the degree of freedom of profiling, so that no relative movement between the sheet and hold-down is possible. As a result, unwanted deformations of the sheet can be excluded and a continuously defined and controlled height of the soil can be achieved.
- step 2 the clamped sheet 5 is guided during the profiling under linear Mitschreiben the assemblies 2, 3 in the profile direction.
- the arrangements 2, 3 move with the sheet 5 to be profiled as a unit.
- the arrangements 2, 3 can be passively pulled along with the sheet feed. The introduction of additional forces in the sheet is avoided and ensures 100% compliance with the sheet feed.
- the assemblies 2, 3 can be actively driven in the direction of the sheet metal feed via motors. In this Mitschreibung the arrangements 2, 3, however, a synchronization with the sheet feed is required. As a result, unwanted deformations of the sheet can also be excluded and a continuously defined and controlled height of the soil.
- the arrangements 2, 3 are brought as close as possible to the forming rollers 6 under clamping of the sheet in order to have the longest possible guide path of the sheet and as long as possible contact time with the sheet.
- the clamping shoe 2b can be adapted to the profile of the sheet 5 during the profiling process in terms of width, height, shape or position. This avoids a collision with the legs 5a, 5b.
- the arrangement 2 can thus follow the bottom of the profile and adapt in height and inclination. As a result, unwanted deformations of the sheet can also be excluded and a continuously defined and controlled height of the soil can be achieved.
- step 3 the clamping of the sympathetic assemblies 2, 3 is released when the clamped point reaches the next roll stand 7.
- step 4 the assemblies 2, 3 are returned to the home position (rest position). Thereafter, steps 1-4 can be performed again.
