Definitions
- the invention relates to a Falzzange for bending sheet metal, comprising a first clamping surface and a second clamping surface, wherein the clamping surfaces are rotatably connected about a first axis of rotation, and a first handle and a pivotally connected to the first handle second handle, wherein the first handle with the first clamping surface is connected.
- the object of the invention is to provide a tool of the type mentioned, which is easy and easy to handle and mobile use.
- Rotary movement of the first clamping surface together with the second clamping surface about the second axis of rotation relative to the second handle causes to bend the clamped sheet.
- the clamping of the sheet takes place by a movement of the clamping surfaces relative to each other about the first axis of rotation and the bending of the sheet by a movement of the clamping surfaces together with the clamped part of the sheet around the second axis of rotation with a continuous movement of the grips to a favorable handling to ensure.
- the first handle In order to release the finished folded sheet metal out of the Falzzange, the first handle is simply opposite to the movement during clamping and folding of the sheet moves so folded sheet can be solved from the Falzzange.
- first axis of rotation and the second axis of rotation are approximately parallel.
- a distance between the axes of rotation is usually less than 20 cm, in particular less than 10 cm, and corresponds to a length of the desired fold or a length of the part of the sheet which is to be bent.
- the clamping surfaces usually extend from the first axis of rotation to the second axis of rotation, so that a sheet is preferably completely clamped in a region between the first axis of rotation and the second axis of rotation, to load this evenly and thus to achieve a clean edge.
- the axis of rotation is essentially fully clamped by the clamping surfaces.
- a clamping in a range between the axes of rotation is possible throughout. This will cause a clean bending of the clamped or force fit between the
- a structurally simple and at the same time robust construction is achieved if a rotatable connection between the clamping surfaces and / or between the second clamping surface and the second handle by a hinge, in particular a
- Rod hinge is formed. As a result, a uniform force transmission over a length of the fold is ensured.
- the first handle is connected via a plate-shaped intermediate element with the first clamping surface, wherein the first handle preferably via at least two, in particular end-arranged, connecting positions is connected to the plate-shaped intermediate element. This ensures a uniform force transmission over a length of the fold, so that a particularly smooth and high-quality bending edge is reached.
- the second handle is connected via a plate-shaped intermediate element with the second clamping surface, wherein the second handle preferably over at least two, in particular end
- connecting positions is connected to the plate-shaped intermediate element.
- the first clamping surface is rigidly connected to the first handle, preferably at an angle of less than 100 °, in particular less than 50 °, preferably 15 ° to 35 °.
- the grips can then be arranged adjacent to each other in a transport position, from which transport position a clamping of a sheet and a folding is directly possible.
- the first clamping surface and the first handle are connected in the region of the first axis of rotation.
- the first clamping surface is rigidly connected to the first handle, wherein in a transport position in which the grips abut each other, the clamping surfaces at an opening angle of 10 ° to 90 °, in particular 15 ° to 35 °, preferably about 20 °, arranged to each other and are open to receive a sheet.
- the Falzzange can then be used directly from the transport position for the folding or sheet metal.
- a moment which is required to move the second handle relative to the second clamping surface about the second axis of rotation is greater than a moment which is required to move the first handle about the first axis of rotation relative to the second clamping surface, so that movement of first handle from the transport position initially triggers a movement of the first handle relative to the second clamping surface.
- a robust embodiment of differently smooth-running axes of rotation can be achieved in a simple manner if at least one spring is provided on a joint which forms the second axis of rotation, in particular a rod hinge forming the second axis of rotation, with which a frictional force acting between relatively movable parts of the joint is insertable into the joint to define a moment required to initiate a movement of the joint, wherein a
- Spring force is adjustable in particular by a clamping screw.
- a clamping screw may be provided on relatively moving parts of the second axis of rotation spring-loaded thrust pieces, so that moving the hinge or moving the second clamping surface relative to the second handle about the second axis of rotation only by overcoming a friction caused by the spring friction or on the relative to each other movable parts of the second axis of rotation acting frictional force is possible.
- more than one spring can be provided in order to introduce a uniform frictional force over a length of the hinge.
- the spring thus acts, for example, directly on a first part of the joint forming the second axis of rotation, which is movable relative to a second part of this joint, and presses the first part with the spring force against the second part, so that for moving the first part relative to the second Part overcoming a frictional force is required, which is defined by the spring force and a coefficient of friction.
- FIG. 5 shows a detail of a Falzzange according to the invention according to FIG. 4.
- FIG. 6 shows a folding pliers according to the invention, together with a metal sheet
- Fig. 7 shows another Falzzange invention along with a sheet.
- Fig. 1 to 3 show a Falzzange 1 according to the invention in different
- the Falzzange 1 a first handle 6 and a second handle 7, wherein the first handle 6 is rigidly connected to a first clamping surface 2.
- the first grip piece 6 and the first clamping face 2 are rotatably connected to a second clamping surface 3 about a first axis of rotation 4, so that a part of a sheet 8 or the like can be clamped between the clamping surfaces 2, 3.
- the second clamping surface 3 is via a second axis of rotation 5, which is the first
- the axis of rotation 4 is parallel, rotatably connected to a second handle 7, so that a clamped between the clamping surfaces 2, 3 sheet 8 by a rotational movement of the clamped sheet metal piece connected to the clamping surfaces 2, 3 bendable or falzbar about the second axis of rotation 5.
- Both the movement of the first clamping surface 2 relative to the second clamping surface 3 about the first axis of rotation 4 and the bending movement of the two clamping surfaces 2, 3 about the second axis of rotation 5 are triggered by a movement of the first handle 6 relative to the second handle 7, so that a terminals and bending sheet 8 with a continuous movement of the first handle 6 relative to the second handle 7 can take place.
- Fig. 1 the Falzzange 1 is shown in a transport position, in which the
- Falzzange 1 has a minimal space requirement and the grips 6, 7 in
- a first handle 6 of Falzzange 1 is moved relative to a second handle 7 of Falzzange 1 from the position shown in Fig. 1 clockwise in the direction of movement 13. After the first clamping surface 2 is rigidly connected to the first handle 6, causes a
- Opening angle ß between the clamping surfaces 2, 3 is therefore 0 °, is shown in Fig. 2.
- the first handle 6 is simply opposite to the direction of movement 13 when clamping and folding, here counterclockwise, moves so that the clamping surfaces 2, 3 open and the sheet 8 are released.
- the gripping pieces 6, 7 are connected via plate-shaped intermediate elements 10 with the clamping surfaces 2, 3, wherein the gripping pieces 6, 7 arranged in end-side areas of the plate-shaped intermediate elements 10 and arranged at the end Connection positions 11 with the grips 6, 7 are connected to a
