Definitions

  • the invention relates to a log splitter with a stand, at the head of a vertical pressure medium cylinder is attached, the piston at its lower end Splitting tool carries, which is guided in a linearly movable manner by means of a slide on the stand is, with two on both sides of the stand in an at least approximate Horizontal plane swiveling, forward-pointing arms, which for Swiveling front handles are assigned.
  • Log splitters of this type are known (see e.g. DE-U-29603020).
  • the holding arms are on sliding pieces pivoted, which in turn on one at the back of the stand attached cross tube slidably mounted and in different sliding positions are fixable. This allows the distance between the holding arms to the diameter of the adjust splitting workpieces. Both arms are independent of each other moving towards and away from each other.
  • Cross wedges have both cutting edges in the vertical longitudinal center plane as well as those in the perpendicular transverse plane. In particular, when using cross wedges, it occurs due to carelessness User before that with the downward movement of the tool the edges of the cross wedge The device's support arms collide, causing the support arms to bend and damage to the cross wedge occurs.
  • the object of the invention is to design the known wood splitter so that the splitting workpiece by manually placing grippers on the holding arms Workpiece can be held securely, but is still safely prevented Cross wedges can no longer collide with the holding arms.
  • This task is carried out in a log splitter of the type mentioned solved according to the invention in that at each support arm, at least Holding member extending approximately horizontally or slightly inclined towards the center is arranged that the holding members facing each other gripping edges for fixing have a workpiece to be split, and that at least that, the gripping edges adjacent areas of the holding members when abutting a moving down Tool part down and when pushing an upward moving tool part are arranged and / or designed to be movable upwards.
  • the holding members consist of rigid Serrated plates, around horizontal axes running parallel to the holding arms are pivotally mounted and by means of springs in their horizontal or slightly inclined positions are maintained.
  • An alternative embodiment of the invention is that at least the Gripping edges adjacent areas of the holding members made of elastically flexible material consist.
  • Spring steel sheet is preferably used for the holding members.
  • the holding members are preferably adjacent to the bottom side of the holding arms attached or stored. They are also preferably plate-shaped and fork-like formed with two spaced plate-shaped fork tines, the Gripping edges are contoured like a saw tooth.
  • the holding arms are at a distance from Workpiece held so that the risk is reduced that a Cross wedge collided with the holding arms.
  • each support arm pointing obliquely upwards and outwards Baffles fixed. If the cross wedge hits one of these baffles, so the respective holding arm is also against the force of the user from the outside The path of the cross wedge is pushed out. Now the cross wedge hits Holding member, this can evade according to the invention, regardless of whether this collision takes place during the downward stroke or the return stroke. Damage to the Holding devices are excluded.
  • the workpiece Due to the fork-like shape of the prongs, the workpiece is in 4-point system held. Even with thin workpieces and correct positioning the cross wedge runs between the fork prongs of the holding members, so that the Holding organs do not have to dodge.
  • the log splitter 10 has a vertical stand 12 with one to the front projecting head 14 on which a vertical pressure medium cylinder 16 is attached, the piston rod 18 passes through the head 14 and one at its lower end Splitting wedge 20 carries, which in turn is attached to a carriage 22 which on Stand 12 is guided.
  • a cross bar 24 On the back of the stand 12 there is a cross bar 24, on which two sliding sleeves 26 are slidably mounted, which by means of pins in the selected sliding positions can be determined.
  • a holding arm 28 projecting forward about a vertical axis pivoted. The two holding arms 28 are thus in a horizontal plane together to one side or to the other side but also in opposite directions and pivotable away from each other.
  • Each of the holding arms 28 supports one Actuating rod 30 with a handle located at its front end.
  • the rear End of each operating rod 30 is with a cross rod 34 on the back of the Stand 12 in engagement, via a control rod, not shown, on the back of the stator 12 acts on a valve lifter. So if one of the handles 32 moved downward, the valve is opened via the valve tappet to the Initiate downward stroke of the riving knife 20. By lifting the handle 32 on Return stroke changed.
  • the wood splitter described in this way is of conventional design.
  • the riving knife 20 with a cross wedge according to FIGS. 2 and 3 can be used to split a workpiece into four parts in one operation there are collisions with the holding arms 28.
  • the cross wedge 21 has two cross-cuts 36, in their Path of movement, the holding arms 28 can be when thin splitting to be split.
  • 28 holding members 38 are in shape under each holding arm stored by serrated plates. These plates 38 are with round iron bars 40 welded, which in turn in downward-facing tabs under the holding arms 28 are rotatably received.
  • the spring device 42 On one end of the round iron 40 there is a wound one Bending spring device 42 which holds the holding member 38 in the horizontal position or in a preferably holds slightly downward inclined position.
  • the spring device 42 is preferably designed so that they both when swiveling the Holding member 38 is tensioned as well as when pivoting downward, so that Holding element after each swivel movement into the horizontal starting position passes back.
  • the spring need only be weak and has only that Task to secure the holding member 38 in the functional position shown. Become now the two holding arms 28 pivoted towards each other, they act as gripping edges trained front edges of the holding members 38 in engagement with the workpiece, with what the position of the holding members 38 is fixed. This does not stress the springs.
  • the holding members 38 designed as serrated plates preferably have two fork-like tine plates, between which there is a cutout, so that the Cross cutting 36 of the cross wedge 21 between the respective fork tines Can drive holding organs.
  • the holding members 38 may happen that one of the cutting edges 36 or both Cross cutting edges 36 strike the holding members 38. This has the effect that swing the holding members 38 down so that no damage occurs can. Should the holding members 38 after passage of the cross wedge 21 upwards swivel back, this also has the subsequent upward gear of the Cross wedge 21 no adverse effects, since the holding members 38 then Swivel upwards, i.e. avoid cross wedge 21.
  • baffle 44 is attached to the outside and is inclined upwards. Meets the cross cutting edge 36 of the cross wedge 21 on one of these baffles 44, the corresponding holding arm 28 is also against the manual force of the user from the path of movement of the wedge 21 pivoted.
  • FIG. 1 is the holding member 38 as a continuous plate with a serrated gripping edge 46 trained. This version is particularly suitable for single wedges 20. If, on the other hand, the cross wedges 21 according to FIGS. 2 and 3 are used, the Cut out the central region of the plates of the holding members 38 so that only two ends flat fork tines remain, between which the transverse cutting edge 36 also then can pass through if thin fissile material is processed.
