Description

Description and claim to the request of May 27, 1981 Title: Manual bending pliers for the production of wire eyelets in a wide variety of shapes and sizes Sizes Field of application: The invention relates to hand bending pliers in a special design for bending wire eyelets made of materials of different thicknesses. The due to this Hand bending pliers shaped eyelets are used in medical and laboratory technology, as well as in electrical engineering and electronics and other areas.

Purpose: With such manual bending pliers there is the possibility of Manufacture of precisely calibrated eyelets and shapes of various material thicknesses using the appropriate interchangeable stencil shapes.

State of the art: In previous processes for the production of eyelets Round-nose pliers and similar shapes were used to round their conical round jaws with wires different diameters were bent to form eyelets.

Criticism of the state of the art: Disadvantages were shown by the fact that the with the round nose pliers firmly connected conical round jaws a repetition of bending Do not allow eyelets with the same diameter, as the diameter is exactly oriented when placing it on the conical round jaws of the round nose pliers.

Task: The invention is based on the task of creating any number To manufacture eyelets with exactly the same diameter.

Solution: This object is achieved according to the invention in that the Manual bending pliers with exchangeable stencil shapes and the clamping device Manufacture of wire eyelets in various large diameters and material thicknesses allows, with a repetition of the process the exact exact unit of measurement in shape? Diameter and size is achieved.

Achievable Advantages: The advantages achieved with the invention exist in particular that because of these hand bending pliers eyelets in any shape, Sizes and thicknesses can be manufactured without using landmarks on the Pliers need to be marked to get the same diameter.

Due to the interchangeable stencil shapes, there is a possibility the exact match with previously manufactured eyelets.

Description of an exemplary embodiment: An exemplary embodiment of the The invention is illustrated in the drawing and will be described in more detail below. They show: Drawing 1 The drawing shows the manual bending pliers in their constructive form Shape.

Drawing 2 Here is the manual bending pliers in their constructive form, the associated stencil shapes with the eyelet bending core applied above, the Clamping device and the clamping head shown.

The thread to screw on is on the lower part of the template shape to see the pliers.

By attaching such threads there is the possibility of replacement various stencil shapes with different sizes - and Shapes of the eyelet bending core.

Further description The form has been changed Commercially available round nose pliers, but without the fixed, conical round jaws. on one side of the pliers with the rounded jaws removed are the template shapes screwed on by means of a thread. The clamping device is on the other side of the pliers firmly installed with the clamping head. The stencil form for making eyelets is made of a suitable material that has a thread at the bottom that can be screwed on owns the pliers. The upper part of the stencil shape is tapered and thus forms the eyelet bending core, the clamping device with clamping head permanently installed on the pliers The template shape screwed on for this is now made possible by inserting the wire and squeezing the pliers to create eyelets by sliding the wire around the eyelet bending core the stencil shape is rotated or the pliers are moved by hand accordingly. Due to the clamping device, the material to be bent during the bending process held. After the bending process has been completed, the pliers are pushed apart and the eyelet is finished. This process can be repeated as often as required, without creating different dimensions and diameters.

By changing template shapes, eyelets can be larger or larger Smaller diameters can be produced0 Another advantage of the manual bending pliers consists in bending eyelets and shapes that are precisely calibrated by hand.

Drawing 3 Drawing 3 shows the process of making eyelets darO The wire is placed between the template form and the clamping device with clamping head. The pliers are now pressed together so that the wire does not slip out of the pliers can. Now the wire is pulled around the eyelet bending core of the template shape by pulling the pliers are turned by hand accordingly 0 After this process has been completed, the pliers are opened and the desired eyelet is made.

Claims to the application dated May 27, 1981, generic term: 1) manual bending pliers for the production of wire eyelets in a wide variety of shapes and sizes of the parts: characterized in that the predetermined construction of the manual bending pliers with template form and in connection with the clamping device and the clamping head represents the unit of the manual bending pliers. Preamble of the dependent claim: 2) Manual bending pliers for the production of Wire eyelets in many different shapes and sizes according to claim 1 characterizing Part of the dependent claim: characterized in that the construction of the manual bending pliers it enables precisely calibrated eyelets to be manufactured by hand based on the specially developed eyelets Template forms with the matching clamping device and its clamping head. Of the Clamping head is characterized in its constructive form and arrangement, that the side surfaces of the clamping head a stop for the exact bending of the Form eyelet stems and wire continuations to form the shaped eyelet. In such a way that the Eyelet stems and wire continuations when applied by pressing on the side surfaces of the clamping head in its imaginary extension a line of intersection to the center of the eyelet bending core.
