This application is a National Stage under 35 U.S.C. § 371 of International Application No. PCT/EP2018/050923, filed on Jan. 16, 2018, which claims priority to German Application No. 10 2017 100 874.8, filed Jan. 18, 2017, the contents of all of which are incorporated by reference in their entirety.
The invention relates to a guide sleeve according to the preamble of claim 1.
The background art has no such guide sleeves, as the stripping claws according to the background art are hammered manually by personal into the stripping tool to be manufactured
The object of the present invention is to overcome the disadvantages of the background art. In particular, a guide sleeve is to be provided that enables the automated manufacture of stripping tools, wherein not only the already mechanically or automatically used stripping pins are to be introduced to save time, but also the stripping claws, which have previously been introduced manually.
The features according to claim 1 lead to the solution of the object.
Advantageous embodiments are described in the dependent claims.
The guide sleeve has a receiving slot on one end and a solid material base on the other end, wherein a machine tool stop is arranged between the receiving slot and the solid material base. The receiving slot is thereby designed as an elongated slot. This has the advantage that received stripping claws can be held in a defined position in the guide sleeve before they can be driven mechanically into the stripping tool to be manufactured for example by a ram. Slipping of the stripping tool in the receiving slot prior to insertion into the stripping tool is successfully prevented.
The receiving slot comprises a stripping claw stop. This has the advantage that the received stripping claw is held in a defined position before it is mechanically inserted into the stripping tool by means of a ram. It is to be prevented that the stripping claw slips too deeply into the guide sleeve.
The receiving slot has a circumferential chamfer in a front outlet area of the guide sleeve. The circumferential chamfer is inclined at an angle of preferably 25 to 35° and more preferably at an angle of 30° with respect to a longitudinally proceeding central axis. It is advantageous here that the stripping claw is guided through the chamfer in a defined area of the receiving slot when loading the guide sleeve through the chamfer.
The receiving slot breaks through an outer wall of the guide sleeve at its longest extension. This is not mandatory. The longest extension describes the two points of an elongated hole that are farthest from each other. Another advantage here is that a broken through outer wall ensures the highest possible flexibility when loading the stripping claw.
A relief slot is present at right angles to the receiving slot. The relief slot and the receiving slot form a plus sign thereby. This arrangement ensures a defined flexibility of the overall arrangement. Furthermore, the outer wall of the guide sleeve breaks through.
The guide sleeve has an inner bore up to the solid material base. In the inner bore, for example, a ram can be provided, which serves for driving out the loaded stripping claw.
Between the machine tool stop and the solid material base, two through bores are present, wherein the two through bores are arranged orthogonally to one another in different planes. In addition, the solid material base has base slots arranged orthogonally to each other, wherein the first base slot extends up to the first through bore and the second base slot extends up to the second through bore. The two base slots have a base chamfer in an end outlet area.
Further advantages, features and details of the invention will become apparent from the following description of preferred exemplary embodiments and by means of the drawings; these show in:
In
The receiving slot 2 is formed as an elongated slot and has a circumferential chamfer 6 in a front outlet area 7 of the guide sleeve 1. The circumferential chamfer is inclined at an angle of preferably 25 to 35° and more preferably at an angle of 30° with respect to a longitudinally proceeding central axis M. The receiving slot 2 respectively breaks through an outer wall 16 of the guide sleeve 1 at its longest extension.
A relief slot 8 is present at right angles to the receiving slot 2. The relief slot 8 also breaks through the outer wall 16 of the guide sleeve 1.
The receiving slot 2 comprises a stripping claw stop 5. It is to be prevented thereby that the stripping claw loaded in the guide sleeve slips too deeply into the guide sleeve.
A machine tool stop 3 is arranged between the receiving slot 2 and the solid material base 4.
The guide sleeve 1 has an inner bore 9 up to the solid material base 4. In the inner bore 9, for example, a ram can be provided, not shown in detail, which serves for driving out the loaded stripping claw.
Between the machine tool stop 3 and the solid material base 4, two through bores 10 and 11 are present, wherein the two through bores 10 and 11 are arranged orthogonally to one another in different planes.
The solid material base 4 also has orthogonally arranged base slots 12 and 13. The first base slot 12 extends up to the first through bore 10 and the second base slot 13 extends up to the second through bore 11. The two base slots 12 and 13 have a base chamfer 15 in an end outlet area 14. The base 15 preferably has an angle of 35 to 55° and more preferably an angle of 45° to the central axis M.
Although only a preferred embodiment of the invention has been described and illustrated, it will be apparent that a person skilled in the art can add numerous modifications without departing from the spirit and scope of the invention.
