Description

Loading device for a system, consisting of an oven, a standing punch press and a push bench for the production of pipes from one Full block The invention relates to a charging device for a system for Manufacture of pipes using the push bench method, consisting of a standing punch press and push bench. Here, square blocks are placed in a round die in a hole press punched in such a way that the perforated pieces retain a bottom, and then these are up a push bench pulled out to the pipe.

When using vertical piercing presses to perform this process, in which the piercer is inserted vertically into the .upright Vi @ Erkantblocks then, on the one hand, when working with the vertical piercing presses, the in Square blocks warmed in a lying position after pulling them out of it only vertically before they can be inserted into the punch; on the other hand after punching, it is necessary to dig the one up from the punching die Fold down pieces of holes in order to be able to continue shaping them lying down in the push bench.

The invention is a device through which in the described Way, the square block was brought to the hole press and the hole piece was conveyed to the push bench will. This is achieved according to the invention by a loading device, characterized by a chair through which the full block coming out of the oven is placed vertically is an insertion device that moves the block from the chair to the Hole die is brought, and a tilting and conveying device, by moving it the perforated piece tilted, brought from the punch press to the push bench and in a push-fit Location is inserted there. Only heschickunbsvorrichtungcn are known so far for horizontal presses that do not have the features of the above combination.

In the drawing is an embodiment s, =: form of the invention in several Illustrations shown, namely show: Fig. I to 3 views of the device, from which the sequence of the individual movements can be seen.

Fig. 4 is a plan for Fig. 2 and Fig. 5 is a plan for Fig. 3.

If the square block a is pushed out of the oven b , it gets into the guide c and slides out of this into the brook d of the upright chair e, which is folded down to accommodate it (Fig. I). By moving the jaw d against the fixed jaw j of the erecting chair e, the block is placed vertically, whereupon it is pushed into the pliers i located on the arm lt of the insertion device by actuating the ejector ä (Fig. 2 and @ .i.

After you close the pliers i the insertion device; the arm lt is lifted by turning the horizontal axis h until the block a is above the die L of the punch press in (Fig. 3 and by opening the pliers i, the block a falls into the die L and is moved back of the arm h (Fig. i). After pulling out the piercing mandrel, the tilting and conveying device for the perforated piece is placed over the perforated matrix in such a way that the guide frame o, which is finitely connected to the arm jr and on which the tilting strip is also attached, overlaps Then the hole piece g is pushed out of the die l and the frame o is pushed in (Fig. 2 and: 1).

When the frame o uni the axis j- is pivoted, the hole piece g is first knocked over by the tilting strip p and then pushed over the inclined plate s onto the flap tr located in front of the insertion point of the push bench t and pivoted so that it is parallel to the direction of impact (Fig. 3 and 5 1.

By lowering the flap u, the hole piece q rolls into the push bench t and can now be pulled out to the pipe @: 'bb. t). Instead of (1, -n arm lt let the insertion device swing around a horizontal axis as in the example, it can also swing uni a vertical axis.

The frame o the tilting and conveying device can also be used as tongs lus ", e-1> ildc-t, @: @ -rden, the # ': e opens to the punch die and closes is moved away from her.

The invention makes it possible to handle the block the way from -Wen to the standing hole press and the hole foot from the standing one To mechanize the punch press to the push bench completely and with simple means. That is especially useful when heavy hole pieces for relatively large and heavy Pipes to be handled are of great importance for a brisk and with as possible working with little heat loss.
