Abstract

The solution ee relates to the stamping of characters into rolled products, especially into hot rolled products. Its essence lies in the fact that on the upper part of the frame (l) of the device for stamping characters into rolled products, a stamping head (2) is vertically pivotably mounted and on the lower part of the frame (l) a vertically adjustable stop (lo) is placed perpendicular to the path of the stamping head (2), while in front of the stop (lo) a fixed jaw (13) is fixed on the frame (l) and opposite it a movable jaw (14) is adjustable on the frame (l).

Description

(57) The solution concerns the embossing of features in rolled metal, in particular in hot rolled metal. It is based on the fact that on the upper part of the frame (l) the embossing device is rolled vertically. The embossing head (2) is vertically swiveled and a vertically adjustable stop is placed perpendicular to the path of the embossing head (2). (lo), wherein a fixed jaw (13) is fastened to the frame (1) in front of the stop (lo) Jo and a movable jaw (14) is displaceably mounted on the frame (1).

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for stamping features in rolled metal, particularly hot rolled metal.

Until now, the marking of rolled steel with a temperature of approx. The worker performing the embossing of the characters is exposed to a great deal of physical strain; capacity must be able to handle punching in all passing rolling, which requires considerable speed and dexterity.

Furthermore, it is exposed to radiant heat and to the immediate impact of the demanding metallurgical environment. All this also manifests in the enormous psychological burden of the worker. The accumulation of excessive physical and mental stress increases the likelihood of a worker being injured as well as the probability of a punching error. It is known to machine markings of rolled metal, for example with a shank cutter, guided by a panto -afle mechanism or by means of a set of discs placed on a pivot arm. These known devices are structurally complex, labor intensive and space-intensive, and other punching devices which have been tested to date for hot-rolled products do not satisfy, in particular because of the high failure rate caused largely by the extremely difficult operating conditions in which the device operates. In some cases the radionuclides used for labeling are demanding on accompanying instrumentation.

These drawbacks are eliminated by the embossing device for the rolled elements according to the invention. It is based on the fact that on the upper part of the frame there is a vertically swiveling embossing head and on the lower part of the frame is placed perpendicularly to the path of the embossing head vertically adjustable stop, with a fixed jaw on the frame. movable jaw.

The rolling embossing device of the invention eliminates the influence of the human factor on the embossing quality; it also removes the overwhelming amount of both physical and psychological stress on the punching worker. It also better meets health and safety requirements.

An exemplary embodiment of a rolling embossing device according to the invention is shown in the drawing, wherein FIG. 1 is a schematic front view and FIG. 2 is a schematic plan view.

On the upper part of the frame 11, an arm 3 is mounted vertically pivotally on the pin 4, at the end of which the embossing head 2 is fixed. On the upper part of the frame 11 is also mounted an electric motor 8 with a gearbox 7. 6 is located in the recess of the lifting lever 5, which is rigidly connected to the arm 3 of the embossing head 2. At the bottom of the frame 6 there is a vertically removable stopper 10 which is connected by a lever 11 to the first drive 12. a fixed jaw 13t a movable jaw 14 positioned opposite the fixed jaw 13 is mounted on a guide rod 16 which is rotatably mounted in bearings 16 on the frame 1. The guide rod 15 is connected to the second drive 19 via an angular lever 17,

When the rolled metal is rolled onto the stopper 10, the rolled metal is clamped between the jaws 13, 14, and the first drive 12 by means of the lever 16 raises the stopper 11 to the upper position. At the same time, the peg 18 disengages the disk 18, thereby swiveling the punching head 2 on the arm 3 and thereby punching the rolled metal. By rotating the pin 6 of the disc 18, which is driven by the electric motor 8 through the gearbox 7, the lifting lever 5 is actuated, which lifts the arm 3 with the punching head 2 to the starting position. Then, the second drive 19, by means of the angular lever 17 and the guide rod 15, releases the clamping of the movable jaw 14 on the rolled metal against the fixed jaw 13. Then the rolled metal is removed and lowered by the lever 11 operated by the first drive 12. Thus, one embossing cycle is completed and the device according to the invention is ready for the next embossing.

SUMMARY OF THE INVENTION

Rolling stamping device comprising a frame with an embossing member under which a positioning and fixing member is located, characterized in that a punching head (2) is vertically pivotally mounted on the upper part of the frame (1) and on the lower part of the frame (1). l) A vertically sealable stop (lo) is placed perpendicular to the path of the embossing head (2), with a fixed jaw (13) fixed on the frame (l) and movably mounted on the frame (l) against the stop (lo) jaw (14).
