Definitions
- the invention relates to a band saw for sawing a rail of a
- Track which can be fastened on a clamp which can be clamped on the rail and provided with a feed device.
- Such a band saw is known for example from DE 298 20 41 1 U1
- An endless saw band is stretched in a frame around three saw band rollers.
- the three rollers are arranged in the form of a triangle.
- For sawing a rail first a vice with a feed device on the rail is clamped.
- the band saw comprises a frame in which four bandsaw blades are mounted, wherein a saw band is stretched around the four saw band rollers and wherein the band saw blade is rotated in a recess of the frame by means of guide elements in a sawing plane.
- the arrangement of four saw band rollers is a low stress of the saw blade given, resulting in a longer life.
- a favorable configuration of the recess of the frame is given, if it is wider in a front, located near the sawing area as in a rear, remote from the sawing area. This causes a high stability of the frame. At the same time, an entire remains
- Rail height severable, because the front portion of the recess is wider than a rail to be sawn rail. Only the rear portion of the recess is narrower but still wider than a rail head to be sawn.
- Rotary axes of the rear saw band rollers clamped plane intersects.
- the recess is thus particularly deep seen from the sawing plane, so that rails with a large rail height can be severed.
- Sawblades have a larger outside diameter than the front ones Have saw band rollers.
- the smaller dimensions of the front saw band rollers allow for sufficient distance to the
- a rear saw band roller is driven by a motor. Due to the larger outer diameter of the rear sawblade roller between saw blade roller and saw blade a ausrechende friction to prevent slippage of the saw blade. In addition, in the area of the rear saw band rollers sufficient space for the arrangement of the engine.
- Transmission gear is arranged displaceably.
- Guide elements are adjustable to each other attached to the frame. This can be the length of the usable band saw blade on a
- Saw band roller can be increased to the torsional stress of the
- At least one guide element has a guide plate with a slot for guiding the saw band. This is made of particularly hard metal and minimizes the wear of the guide elements.
- Favorable for the stability of the band saw is when the recess of the frame is bridged with a bracket and when the bracket
- Connecting device for fixing the band saw on the vise includes.
- the bracket reinforces the rigidity of the frame, which ensures a high quality of cut.
- the frame has a removable lid on a bottom.
- Fig. 1 oblique view of a band saw
- Fig. 3 band saw on a vise before a sawing
- Fig. 4 band saw on a vise after a sawing
- Pipe frame 13 is arranged. This serves as a protective device against damage to the band saw 1 on a construction site or a loading area.
- Another security element forms a mounted on the underside of the frame 2 lid 14.
- releasable fasteners are provided to remove the cover 14 for maintenance can.
- Fig. 2 the band saw 1 is shown from below, with the front facing the terminal plate 10 to the right.
- the saw band 7 is stretched around two front saw band rollers 15 and two rear saw band rollers 16.
- Each saw blade roller 15, 16 deflects the saw blade 7 by an angle ⁇ of approximately 90 °, so that the saw band rollers 15, 16 are arranged approximately in a rectangle.
- the guide elements 17 are mutually displaceable on the frame. 2
- Guide element 17 comprises two guide rollers 19 which are mounted on eccentrics. By rotating the eccentric guide rollers 19 are mutually adjustable. At least one guide element 17 also includes a guide plate 20 with a slot in which the saw band 7 is additionally guided.
- the recess 6 is in the front region, close to the sawing plane 1 1
- the rear saw band rollers 16 may be formed with a larger diameter than the front saw band rollers 15. This increases the friction between the saw blade 7 and the driven rear saw band roller 15 and reduces the bending stress of the saw band 7th [28]
- the recess 6 of the frame 2 is guided so far back that it intersects a spanned by axes of rotation of the rear saw band rollers 16 plane 21. This is at a limited depth of
- the arrangement of the saw band rollers 15, 16 and the smaller diameter of the front saw band rollers 15 also allow a limited width of the frame 2.
- the band saw 1 remains operational even in tight spaces. This is particularly important when sawing in the area of switches or crossings, where rails 18 are in close proximity to each other. The same applies to an additional busbar.
- a rear saw band roller 16 is mounted in a displaceable bearing 22.
- the clamping device 4 comprises a guide 2 mounted in the frame 2 of the bearing 22 and a
- Threaded spindle as adjusting device.
- clamping direction runs in a diagonal of the frame 2 and allows a large adjustment.
- An operating element for rotating the threaded spindle can be made removable. This ensures a compact design.
- Figures 3 and 4 show the band saw 1 in use on a
- the band saw 1 and a base 23 of the tensioning rod 9 are shown in section.
- the vise 9 includes with the base 23 to be sawed rail 18 of a track 24.
- the base 23 is clamped to the rail web.
- a carriage 26 of the feed device 12 is vertically adjustable.
- connection plate 10 With the connection plate 10, the band saw 1 is attached to the carriage 26.
- the band saw 1 is inclined by an angle ß to avoid a collision with the rail 18 when sawing.
- the usable portion a of the saw blade 7 is rotated in the sawing plane 1 1.
- Feed device 12 moves at a suitable feed speed down.
- the long saw blade 7 and the low bending stress due to the four saw band rollers 15, 16 allow a high
- a change of the saw blade 7 can be carried out in a simple manner. This is only a removal of the lid 14 and a
- the invention also relates to other embodiments with at least four
- Saw band rollers 15, 16 For example, a separate tension roller can be provided so that the saw band 7 is stretched with this fifth roller to the other four saw band rollers 15, 16.
