DE3205754A1 - Method and device for removing ferritic chips from bores - Google Patents

Abstract

According to the invention, provision is made for a tool holder to be designed in such a way that chips are removed from bores with a change-pole or pole-reversible bar magnet which is located at the tip of the tool. The device serves to remove the chips from deep bores or in tubular workpieces in order to avoid damage to the following cutting tools. The pole-change or pole reversal is integrated in the tool shank. The pole change or pole reversal can be actuated mechanically, hydraulically, pneumatically or electrically as a control element. Like any other cutting tool, the tool described can be inserted into the tool carrier of a lathe or a machining centre. During the plunging movement of the tool into the bore, the pole reversal is effected by magnetisation. Owing to the fact that the bar magnet is magnetic, it attracts the chips located in the bore and keeps a firm hold of them. Delayed demagnetisation via the control elements referred to is effected by the return movement of the tool slide so that the chips are released and can fall into the collecting container. This method and device removes chips from bores in an optimum manner.

Description

P A T E N T - B E S C H R EI B U N G

- Method and device for removing ferritic chips from holes ========================================= The method is intended to from t & Qfen bores that are not rinsed free of chips due to the coolant kõmlen, or in the case of tubular material in which the split effect is absent, the Remove machining chips to avoid damaging the subsequent machining tools to avoid.

When machining tubes on automatic lathes there is usually long chips that have to be removed by the operator with the chip hook, otherwise the tools can be damaged by the chips. This is This is possible without problems with conventional automatic lathes, but the operator is as a result, it is strongly tied to the machine that uses such a tubular material is loaded.

With today's NC technology, it is no longer possible for the operator reach into the machine with a chip hook and remove the chips from there safety-related reasons / regulations the protective and injection doors electrically is locked and can only be opened when the machine is at a standstill.

In other words, to cut the chips on an NC bar lathe The operator must remove the machine that interfere with the machining process shut down, wait for the door to lock and only then he can remove the annoying and hindering chips with the chip hook. This Repeated manual swarf removal as described here results in one not inconsiderable loss of time.

SHEET 2 for the patent description of the application: =========================================== === ferritic method and device for removing / chips from bores ======================================== ======= If these long chips are not removed in time, this leads to one Damage to the machining tools, which has the consequence that the manufactured parts are no longer true to size, due to these damaged machining tools, such as E.g. broken teeth of a reamer, or broken inserts on hard metal tools or broken taps, etc. The replacement or repair of these Machining tools is associated with high costs. Because only by monitoring the Machine that the timely removal of the chips is guaranteed, is the operator tied to the machine and therefore it is difficult to manage optimal multi-machine operation perform.

According to the invention it is therefore provided that a method and device for removing ferritic chips from bores to protect the machining tools and a smooth process or disruption-free processing sequence -in the machine is used.

It is provided that the chips from the holes with a pole-changing or pole magnet with reversible polarity must be removed.

It is provided that a tool holder is designed so that on its tip is this bar magnet. The pole switching or polarity reversal should be integrated or introduced into the tool shank. The operation of the polarity reversal or pole changing should be done mechanically or via any other auxiliary control elements, such as hydraulic cylinders, lifting magnets, etc.

B L A T T 3 for the patent registration of the application: ======================================= ferritic method and device for removing / chips from bores ================================ This tool described here is like any other machining tool, so to speak in the turret head or tool carrier of the lathe / automatic machine / machining center to use.

When the tool slide is immersed, the polarity is reversed or pole switching of the bar magnet to magnetization by a mechanical or also via any other auxiliary control element (as described above).

Because the bar magnet is magnetic, it pulls the one in the hole any chips and holds them in place. The backward movement of the tool With the slide, this bar magnet is demagnetized via the control elements mentioned, so that the chips are released and these chips into the chip collecting container can fall.

This forward and backward movement of the tool holder can be carried out in rapid traverse done, so it is only a small amount of time to remove the annoying evil chips Becoming master and magnetizing the part to be machined is avoided.

The procedure described here solves the problem of elimination or Removal of ferritic chips from bores in an optimal way.
