Description

Annealed goods container for small iron utensils and & g1. The invention relates to an incandescent --SiCH t> u g. Like. Clutbeh.älter for hardware stuff the incandescent been in use "utbehälter a thy are filled with to be hardened or to be compensated well and z. B. arranged in a salt bath The heating through the entire material, i.e. from the outer layers to the core, can be promoted by shaking the annealing material container by hand, whereby the hardened material mixed up and mixed up and the molten salt is given the opportunity to get to the individual pieces of the annealing material. This work process, which must be carried out by hand directly above the Salzhad, is extremely laborious and unreliable. Despite the shaking, there is no guarantee that the annealing material is heated evenly through and through, because shaking by hand results in only irregular mixing up of the annealing material e to avoid the above-mentioned disadvantages and to create an annealing material 'container with which a uniform heating of the material to be treated is achieved.

The annealing material container according to the invention is characterized by conical end caps and end rings divided into a number of superimposed chambers, which can be opened and closed one after the other by raising and lowering the hoods. HierduTch gives you the opportunity to gradually move the item to be treated from the top Chamber in certain and delimited quantities of any number below To supply chambers, from which it then passes into a Samnielraum. This will uniform and thorough heating of the individual pieces of the annealing material their passage through the individual. Chambers guaranteed.

The conical Abschlussbauhen can be arranged on a common axis in such a way that upon movement, e.g. B.! A lowering movement, the first chamber opened, opened, the next chamber closed, the next but one chamber is opened again etc., while at the opposite move the first chamber closed, J, second open, third closed etc. Through this alternating movement the annealing material to be treated is gradually led from one chamber to the next following chamber.

Also the collection room for receiving the items to be treated after the step-by-step hike through the individual chambers is provided with a cap, which according to one embodiment of the invention simultaneously as a guide for the the final hood. the axis supporting the individual chambers can be formed, by being connected to a piston guided in the container.

The Bewegun., - the Abechlußhauben for .einzelnen chambers can both manually and mechanically a.ls, eg by a controlled eccentric take place, and the process of opening and closing of the Boards may be repeated at regular intervals. . The number of strokes or control movements used for the closing hoods of the individual chambers determines the amount of annealing material which is to be guided from one chamber to the other.

After the material to be annealed has passed through the individual chambers and Accumulation of the annealing material in the collecting space. can through another tax movement, movement the Tragachsie for the individual closing hood, en the collecting space opened and the Annealed material led out of the container in a steady stream and z. B. in one Quenchers are dropped. For this purpose, an movable stop may be provided, which usually controls the lowering movement of the hoods limited; this stop can be swiveled to empty the annealed material container, so that the closure hood for the plenum or the piston connected to it so is moved far that the collected annealing material fall out through the bottom of the container can. For the purpose of easier removal of the accumulated annealing material, the The bottom of the container is conical in accordance with the shape of the movable end cap be designed to expand. The movement of a pivotable stop for emptying the annealed material container is preferably done automatically by z. B. one with the stop connected lever strikes against a support point that pivots this stop.

In the drawing, an annealed material container according to the invention is for example shown. Fig. I shows a vertical longitudinal tunnel through a weld pool used annealed material container according to the invention in a: certain position of the Closing hoods of the single chambers.

Fig. 2 shows a corresponding section with the closure hoods in a different position, and - Fig. 3 shows a section of the annealing material container placed on a quenching vessel in the emptying position for the annealing material.

It denotes a a salt bath container and b the annealing material container immersed in the molten salt. The annealing material container b consists essentially of a perforated outer sheet metal jacket, el for the passage of the molten salt into the interior of the container; Inside the perforated sheet metal jacket, a number of shut-off rings h corresponding to the desired number of chambers are welded in at certain intervals. In the illustrated embodiment, three chambers and consequently three insert rings are provided. A central axis-tree is passed through the container, on which three perforated end caps c, - which preferably have the shape of a cone, are attached. At the lower end of the axle a further end cap c is attached, which is connected to a Dichtungskolbeng, which is inserted into the inwardly drawn lower side wall of the perforated sheet metal jacket and is used to guide the axle. The movable closure hoods c are attached to the axis e at certain intervals in such a way that they are in connection with the inserted. Rings li alternately close the individual chambers x, y and z so that the annealing material filled in is retained in these chambers.

The axle, which is passed through the lid of the annealed material container, is connected to a pivotably mounted handle k which can be controlled mechanically by hand or by an eccentric. By controlling the lever k by hand or mechanically by eccentrics, the A, chsee and thus the end cone for the individual chambers are alternately raised and lowered. In the depressed position, the lever rests against a stop provided on the lid of the annealing material container, which can be pivoted by means of an angle lever firmly connected to it, as shown in Fig. 3 .

After the heating process has ended, the annealing material container can be placed on a water container iv, expediently with the aid of supports f, to quench the annealing material. A stop p is provided on this water container which pivots the angle lever 1 when the annealing material container is placed on the Wassex container.

The device works as follows.

In the position of the parts shown in Fig. I, a certain amount of material to be treated is brought into chamber x and the annealing material container is placed in the molten salt either by hand or by a mechanical device. After a desired time, the lever k is lifted by hand or mechanically, so that the axis e with the conical end caps c is lifted and the chambers x and 2 are opened. Part of the small ironware falls through the space formed between the upper end hood: ec and the upper insert ring into the chamber (position Fig.2). After a desired time, the lever is lowered again; so that the chambers x and z are closed again and the chamber y opened, so that now a certain amount of the annealing material can fall from the chamber y into the chamber z (position Fig. i). After a period of -gewünschten Hebelk is raised again overall, and it is another desired amount of the material to be annealed from Kammerx y in the chamber and from the chamber such in the collection chamber. q. The intermittent lifting and lowering movement of the cover hoods for the individual chambers takes place until the entire annealing material is arranged in stages in the collecting space q .

Then the incandescent material holder is after the incandescent material has been heated evenly. removed from the molten salt either by hand or by a mechanical device and placed on the water bath container by means of the supports / for quenching. As a result of the placement movement, the angle lever 1 is pivoted with its stop, so that now the lever k can be moved further downwards. As a result of this movement, the guide man steps out of his guide, and the accumulated annealing material can flow through the conically widened bottom opening of the annealing material container in a steady stream into the quenching or water bath. This ensures that the material to be annealed is quenched evenly in the water bath.
