Definitions
- the invention relates to a pressing tongs for deforming a Workpiece, with a pliers head having two cover plates, on which a stationary press jaw and a linearly displaceable guided press jaw are provided, at least one of the press jaws is arranged interchangeably, with a Toggle lever drive for the movement of the guided press jaw, the one movable handle and one on a fixed handle has articulated toggle link, with a positive lock consisting of a toothed segment and a swivel pawl for the reproducible reaching of an end position, and with a return spring to achieve the open position of the press jaws and the handles.
- the pressing tongs can be used to manufacture solderless connections between power lines and associated ones Connection parts by pressing a workpiece constructed in this way be applied.
- the crimping pliers can be used if workpieces are permanent should be deformed.
- the formation of the press jaws is aimed depending on the pressed shape of the workpiece to be achieved.
- the press jaws have one or more dies, one on top of the other are coordinated and depending on the application also a very can have complicated shapes.
- a pressing tongs of the type described in the opening paragraph is known from DE 21 49 167 C3 known.
- This crimping pliers is constructed in plate construction. It has a pliers head, two cover plates, two Side plates, a handle plate provided on the fixed handle and has several bolts and pins with which the parts of the Pliers head are held together.
- Toggle lever drive consisting of a movable handle and a toggle lever bracket arranged, which drives a guide plate, the carries two pens.
- One pin is for articulation of the free End of the movable handle formed during the other pen for interchangeable storage of an interchangeable Press jaw serves.
- Both the movable and the fixed press jaw is interchangeably mounted in the pliers head, the fixed press jaw is supported by projections on the cover plates and otherwise by means of a detachable bolt between the cover plates is pinched.
- the movable press jaw is on the Guide tab attached and is provided by one there Nose held.
- the press jaws are already basic interchangeable and therefore interchangeable with other jaw shapes intended.
- a disadvantage of this known pressing tongs is that large number of necessary parts as well as the arrangement of the Return spring in the pliers head in the area of the press jaws.
- the US 5,113,727 shows a clamp with pressing jaws are held interchangeably on swivel jaws of the clamping pliers.
- the Swivel jaws and the press jaws point towards each other Pages a complicated surface design, where in this way contact surfaces for the transmission of the clamping forces are formed.
- These pliers are also used for storage the press jaws on the swivel jaws and thus the transmission the pressing forces or reaction forces over a multidimensional flat design. It is also a protection against loss provided that the automatic release of the press jaws from the Avoid swiveling jaws when the pliers are open.
- This Loss prevention consists of a pullable pin, the one laterally aligned bore in one leg of the Press jaw and in the body of the swivel jaw interspersed and by a ball catch is held. This pen is used during the Clamping process not subject to force.
- the invention has for its object a pressing tongs provide the type described above, the one as possible has a simple structure made up of few individual parts at least one of the press jaws, but preferably both press jaws, can be easily replaced and yet the press jaws in the Pliers head are permanently supported reliably, so that the intended end position during the pressing process between the Press jaws are reproducibly observed.
- this is the case at the beginning of a pressing tongs described type achieved in that for the implementation of Interchangeability and to absorb the press forces at least one of the press jaws has a double bearing from a first bearing with pullable bolt and edge-closed opening in the Press jaw and from a second bearing with a fixed bolt and Open edge opening is provided in the press jaw.
- the invention is based on the idea of interchangeability the press jaws have a double bearing or two-point bearing to provide.
- the two bearings are spaced from each other, so that the relevant press jaw under the bearing effect is held against rotation in the pliers head.
- One of each Bearing consists of an opening in the edge closed in the Press jaw and a pullable, d.
- H. detachable or removable and reusable bolts that hold the two cover plates enforced and the border-closed opening in the concerned Press jaw reaches through. This bolt is for immediate Recording the pressing force or reaction force trained.
- the other bearing is attached to a fixed bolt in the pliers head the cover plates in connection with an open edge formed in the relevant interchangeable press jaw.
- Such a fixed bolt is understood to mean a bolt which can be assembled or disassembled, but which can be replaced the press jaw is not released.
- the interchangeability the press jaw can relate to that To exchange the pair of press jaws for another pair of press jaws, if e.g. B. wear after a corresponding period of use Die area has taken place.
- the interchangeability relates but also insists on a pair of press jaws with a first Die form against another pair of press jaws with another Exchange or replace the die form in order to use one and perform the same pressing tongs different pressing work can. Due to this double bearing, the place and on the other hand, the relative angle with which the press jaws in Pliers head are provided, clearly and reproducibly set.
- the new pressing tongs are particularly simple and consists of comparatively few individual parts. Compared to the generic pressing pliers are no longer needed the guide piece for the movable press jaw. Even the firm one Handle does not need to reach the front end of the pliers head be continuously formed. Due to the double bearing of Press jaws result in a better non-positive connection between press jaws and cover plates. The resilient mobility the cover plates to each other is used advantageously. When tightening the fixed press jaw also becomes this connection Support the cover plates against each other and thus for bracing of the pliers head. The over on the movable press jaw the pressing force exerted is transferred directly, the toggle lever drive having the toggle lever tab is used directly acting. After all, they can Press jaws can also be manufactured in plate construction. On the other hand, it is not out of the question, even in investment casting generated press jaws to use.
- the return spring is in the Pliers head arranged between the cover plates and on the fixed Handle on the one hand and on the knee lever bracket on the other supported.
- the return spring no longer engages the movable press jaw, but on the knee lever bracket. In this respect, this is not necessary when changing the movable press jaw Attaching or detaching the return spring, so that the Replacement process of the movable press jaw basically is simplified. But also the direction of the force arranged and stored return spring is optimal. After Carrying out the pressing process and reaching the end position the return spring guides both the handles and the Press jaws back into the open position.
- the return spring is protected in the pliers head and blocked z. B. not the gusset area between the handles.
- the invention can be particularly advantageous for the movable Use press jaw.
- the guided press jaw is included their open edge breakthrough directly on the front end of the movable handle supported in the fixed bolt.
- the pullable bolts and the fixed bolt are in slot holes guided in the cover plates.
- the guide tabs are also omitted the pins and the additional hinge points, so that too game required there, so that not only the number of Items is reduced, but also the end position adheres to more precisely.
- the pullable bolt can also be used here basically in a bolt body and an easy to handle Knurled screw can be divided.
- connection tab that over the pullable Bolt of the guided press jaw is detachable.
- This connecting strap transmits the return force of the return spring on the movable guided press jaw, so that after a pressing process also the open position between the Press jaws are reached again.
- the connection tab is on the pullable pin of the guided press jaw articulated so that with the loosening or tightening of this bolt at the same time the connection lifted or manufactured via the connecting strap becomes.
- the pullable bolt of the guided press jaw can be a positioning stop exhibit.
- the positioning stop the for example the relative position of the insulation of an electrical Head relative to the press jaws, in association with the respective press jaw can be used. A separate detachable There is no need to fasten this positioning stop on the pliers head. Of course, it is necessary to establish the affiliation between Positioning stop and movable press jaw must be observed.
- the exchangeable press jaw can be assembled in a plate construction be. This also results in simple manufacture the press jaws as well as the possibility of the press jaws also to be provided with relatively movable elements, for example one movable in the press jaws relative to the die Attack. Because such a stop of the respective press jaw exactly is assigned and for example in the central region of the press jaw is arranged, such a stop is part of the press jaw and is replaced with this.
- the fixed handle can be at its free end in the pliers head have a double bearing made of two bolts, of which at least one is detachable.
- the double bearing can be used according to the invention, if one of the bolts is designed to be pullable.
- This possibility serves the purpose, for example after a break of the return spring swivel the fixed handle relative to the pliers head to be able to easily remove the defective spring and against a to be able to replace new return spring. It usually plays It does not matter whether a twisting tool is used to loosen the bolt must be used or not.
- find at the other pullable bolts preferably using thumbscrews, so that the exchange of the press jaws without tools and so that it can only be done by hand.
- the forced locking is protected in the area of the pliers head housed.
- the free end of the movable handle points the tooth segment of the forced ratchet.
- the mobile Handle is thus also a tooth segment of the forced locking trained and can be done in a punching process in simple Create way.
- the associated pawl is in the free space swiveling between the cover plates and movable against spring force suspended, so that an opening and closing path started can only be ended after it has run through completely.
- This arbitrary Swiveling and unlocking allows one for example, an incorrectly inserted workpiece Interrupt the closing process to damage the press jaws to avoid.
- the pawl can be in a neutral position be pivoted, in which the movement of the guided press jaw releases in both directions.
- the arbitrary pivoting of the pawl is limited, however that an overextension of the spring loading the pawl is excluded.
- the pliers head can be made as a hollow housing from a distance cover plates connected to one another by means of pins and bolts be trained.
- the cover plates have a C-shape, and the interchangeable press jaws are in two on top of each other perpendicular directions in the space between the Insertable cover plates. This embodiment is special advantageous in connection with the design according to the invention.
- the pressing tongs shown in FIG. 1 have a pliers head 1 on, consisting essentially of two identically designed cover plates 2, 3, which has a plurality of pins and Bolts are kept at a distance from each other, as is particularly the case 5 can be seen.
