Definitions

  • the invention relates to a pressing tool or pressing device of the plier type, which has a device body part to which a first handle at its front end is rigid, and a. second handle is articulated at its front end, two cooperating processing elements which can be acted upon by the handles and which engage a work piece are arranged between the articulation point of the second handle and the free rear ends of the handles.
  • Devices of this type are known and a device in which one machining element moves along a circular path opposite the other is e.g. in which R.W. Trickle on July 3rd U.S. Patent 2,752,676 issued in 1956.
  • the object of the invention is to improve the tools or devices of the type mentioned, in particular with regard to the fact that with the scissor-like approach movement of the two handles to one another, precise, straight-line guidance of one of the processing members relative to the other is achieved in a simple manner, and that in one Advantageous further development of the inventive concept, a favorable power transmission from the articulated handle to the straight-line processing element is made possible in the final phase of its approach movement to the other processing element. Furthermore, an effort is made to create an easily installable jaw carrier for the movable machining element.
  • the device which is made of any suitable material, e.g. Metal or plastic (optionally glass fiber reinforced) can be produced, has a device body part 10 with a front end 10a.
  • a first handle 11 is rigidly connected to the device body part 10 with its front end 11a in order to form a rigid attachment unit 100 together with the device body part 10.
  • a second handle 12 is pivotally connected at its front end 12a to the front end 10a of the device body part 10 by means of a pivot pin 13.
  • the pivot pin 13 forms the articulation point or the pivot point of the handle 12.
  • the assembly 100 essentially consists of a carrier plate 101 from which an edge 102, a hub part 103, a pair of guide blocks 104, which form protruding guide members, and possibly an end stop block 105 protrude at least to one side (ie facing the viewer) .
  • these elements preferably protrude on both sides of the Carrier plate 101 emerges, as can be seen in FIG. 3.
  • the second handle 12 is preferably U-shaped in cross section or has two side parts 12 ', 12 "separated by a central free space, and includes the support plate 101 with these side parts or legs 12' and 12".
  • the guideway is formed from mutually parallel edges or inner surfaces 106 ', 106 "of a window 106 provided in the carrier plate 101 and in the hub part 103, and from the mutually facing surfaces such as 104' of the two guide blocks 104.
  • the window 106 ends at the blocks 104 facing end with a transverse edge 106a located above these blocks.
  • the fulcrum 13 of the handle 12 is located away from the guideway 106, specifically in the direction perpendicular to direction A of the guideway, and on the opposite side of the guideway from where the handle 11 is located.
  • the articulated handle 1.2 thus extends from the pivot point 13 to the guideway 106 and beyond.
  • the jaw support 20 can be designed at its first (upper in the drawing) to a machining or baking element for a work piece, not shown, or with an interchangeable such element, e.g. a press jaw 25, held by a rivet 26, can be equipped.
  • the second transverse edge 106b of the window 106 can be designed to form a cooperating processing or baking organ, or with an interchangeable such cooperating organ, e.g. the jaw 27, which is held by a rivet 28, can be equipped.
  • the jaw support has the shape of an inverted U whose legs 20 'and 20 "extend below the window 106 and there, essentially Lichen in the area 101a between the two guide blocks 104, the carrier plate 101 in the same way as the legs 12 ', 12 "of the second handle 12, but from the opposite side, which is best seen in Fig. 3.
  • cooperating transmission members which are formed by contact surfaces 12c 'and 12c "or 20a' and 20a".
  • the contact surfaces 12c ', 12c "arranged on the two legs 12', 12" of the second handle 12 are straight or flat in the example shown and extend radially with respect to the pivot point 13.
  • the ones on the two legs 20 ', 20 "of the jaw carrier In the example shown in FIGS. 1 to 3, 20 arranged contact surfaces 20a ', 20a “have a first part m facing the front end 10a of the device body part, which is curved as best seen in FIG. 4, and a second part n adjoining it, which is flat and also runs radially with respect to the pivot point 13.
  • depressions 20b ', 20b are provided for the engagement of both ends of a bow-shaped spring 14 with bent legs.
  • the web of the spring 14 passes through an opening 107 in the support plate 101 and supports the kinks such as 14a on both sides of the carrier plate 101 against the projecting edge 102, so that the spring 14 presses the jaw carrier 20 continuously against the second handle 12.
  • the movement of the second handle 12 is through two stop organs limited.
  • the first stop element determines the open position of the device and is formed from an end surface 102a of the projecting edge 102, against which a projection 12d of the second handle can rest.
  • the second stop element determines the closed end position of the device or the inner end position of the jaw support 20 and is formed by the stop blocks 105 (one block on each side of the carrier plate). However, it can be seen from the drawing that the function of the second stop element can also be performed by the lower surfaces 104a of the guide blocks 104.
  • the course of the guideway determined by the angle a, which includes the direction A of the guideway with the direction B of the first handle 11, is in the order of magnitude of 70 ° in the example shown, and can generally be in the embodiment according to FIG Of the order of 30-120.
  • the course of the contact surfaces 12c ', 12c "and 20a', 20a” is chosen such that the said contact surfaces extend essentially radially to the pivot pin 13, the guideway running essentially at right angles to these contact surfaces when the device is in the closed state.
  • the essentially radial course of at least part of a contact surface is due to the previously mentioned sliding movement.
  • the course of the two handles 11, 12 can, for example, also extend essentially parallel to the direction A of the guide track 106 if the handle 12 runs, for example, between the pivot point 13 and the surface 12c 'as shown in FIG. is shown 1, but then bent at about 90 °, or when the handle 12 are the same extends from the pivot point 13 at parallel with the direction a, and the surfaces 12c ', 12c' disposed on a projecting from the handle arm.
  • the first handle 11 in the closed position with the second handle 12 essentially parallel.
  • the second handle 12 After inserting a work piece between the processing members 25, 27, the second handle 12 is brought up to the first handle 11, the curved parts m of the contact surfaces 20a ', 20a "initially being in contact with the contact surfaces 12c', 12c" in an essentially point-like manner pass this on.
  • the contact zone of the contact surfaces 12c 'and 20a' or 12c “and 20a” merges with the flat surface part n, which brings about and brings about more than just point contact, namely surface contact better power transmission is achieved.
  • the fact that the contact surfaces 12c ', 12c "run at right angles to the guideway in this final phase also contributes to the effective transmission of force.
  • FIG. 5 shows a modified embodiment of the device according to the invention, in which the point contact of the contact surfaces 12c ', 12c "with the contact surfaces 20a', 20a” is achieved in the initial phases of a machining operation in that the surfaces 12a ', 12a " butt approximately at the point where the surface portions m and n of FIG. 4 each have a front corner o, wherein the contact surface 20a ', 20a "in all its usstreckung a planar.
  • the length C of the window 106 is preferably chosen so that it is at least equal to the length D of the jaw support 20 (preferably without the processing member 25), so that the jaw support 20 can be easily inserted into the window 106 from the side.
  • the jaw support 20 With the sliding movements In the guideway, the jaw support 20 is guided in such a way that its upper, undivided part is formed by the side surfaces or edges 106 ', 106 "of the window 106, and its lower part, formed by the two legs 20', 20", on the one hand by the guide blocks 104 , and on the other hand is guided by the region 101a of the carrier plate located in between.
  • the free length of the window 106 is reduced in such a way that the jaw support 20 is enclosed and secured against falling out laterally , because the lower ends of the legs 20 ', 20 "can then no longer exceed the lower transverse edge 106a.
  • the window 106 can also be shorter, and the jaw support 20 can then be made of two parts which can be screwed together after being inserted into the window (eg middle part plus one Schnkel and a separate second leg) exist.
  • the second handle 12 like the jaw support 20, is also guided by touching its legs 12 ′, 12 ′′ with the support plate 101 in the region 101b.
  • the edge 102 and the hub part 103 expediently have the same width or thickness dimension E. like the second handle 12.
  • the contact surfaces on the jaw support 20 or on the second handle 12 are replaced by at least one protruding pin which is acted upon by at least one contact surface on the other element, the at least part of which extends radially.
