DD141794A1 - CLOSED EXIT FRAME FOR SEMI-FINISHED - Google Patents

Description

He f e nd in a n c e c e ss

a) Title of the invention; · 'Closed spout for semi-finished products

b) Field of application of the invention:

The invention relates to a closed outlet channel for semi-finished product with round / n cross-section and preferably of great length, which is machined on oblique roll straightening or peeling machines and additionally performs a rotational movement during the translatory exit from the machine.

c) Characteristic of the known technical solutions:

For reasons of safety and reliability, the semifinished product, which runs out of tapered roller straightening or peeling machines, must be guided in closed channels and be received in full length before it can be thrown off into the storage arranged laterally to the channel.

In this case, discharge chutes with ejection on both sides are preferably used, since they allow continuous operation of the upstream processing machine in the event of discontinuous emptying of the storage.

These outlet channels consist essentially of a chamber, the lower longitudinal side by two opposing bottom flaps closable iet.

Along the butt joint of the bottom flaps below the gutter chamber, a partition between the side-by-side storage is arranged, wherein the upper end face of the partition wall carries a pointed roof-shaped strip. Through this bar is achieved that the semi-finished after

Opening the respective bottom flap is also dropped into the appropriate memory-is ·

The focal point of this gutter training is that this, for? Semifinished product of greater rod length, very bulky, since it can not be supported in the available ejection area, and must not be subjected to any pressure movement to ensure the bottom flaps.

Because of their cantilevered construction, such outlet channels can only be used for relatively short rod lengths.

d) Aim of the invention:

It is an object of the invention to provide a more favorable in terms of their cost, closed discharge chute for use immediately behind Schrägrollenricht- and peeling machines, which allows ejecting the semifinished product to both sides even with large rod lengths.

e) - Explanation of the essence of the invention:

The invention has for its object to change the technical structure of discharge chutes for semi-finished products with a round cross-section, such as round steel and tubes so that their length is not limited by a self-supporting Bauweise'.

According to the invention the object is achieved in that the gutter upper part by intermediate webs in two side by side ^; lying chambers is divided by a likewise double-sided bottom flap, the flap sides are at an obtuse angle to each other, can be optionally closed or opened. The gutter upper part is further attached to the upper end sides of two-armed and vertically pivotable by means of working cylinder support lever, which are mounted approximately vertically below the longitudinal axis of the emerging from the upstream Schrägrollenricht- or peeling machine semifinished product in the gutter stand.

The vertical position of the pivot point of the support lever in the gutter stand was preferably chosen so that · the longitudinal axes of the outgoing semifinished product on contact with the wear

-'3

surfaces of the gutter lining from the right chamber to the left chamber, so in both ejection positions of the outlet channel 5 and the pivot point of the support lever approximately a gleich-. forming a triangular triangle.

For safe guidance of the expiring semi-finished product, the channel in the gutter stand is adjustable, and can thus be adjusted in height and inclination of the direction of the expiring semi-finished product. In the ejection position on the left, the channel is inclined to the right, so that the right-hand chamber is located obliquely below the left-hand chamber, the helically running out semifinished product is picked up by this left-hand chamber. After the machining process is completed and thus the break-in phase is completed, this chamber is opened by pivoting the bottom flap. As a result of its own weight, the semi-finished product rolls out of the trough chamber and falls into the left-hand store arranged along the outlet trough. As soon as the storage volume on this side has been reached, the discharge chute is swung over and the storage tank arranged on the right side of the chute is filled. During this time, the left storage tank is emptied.

f) embodiment:

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing show: Pig. 1: The front view of an outlet channel according to the invention in left-side ejection position and

Pig. 2: the same view, but in the right-hand ejection position.

The closed discharge chute consists essentially of a gutter stand 1 and a vertically above the upper trough upper part 2 arranged above, which by means of intermediate webs 3 in two adjacent chambers 4; 5 is divided. The lower longitudinal sides of the chambers 4; 5 are by a common bottom flap 6, the flap of which 7; S at an obtuse angle to each other, mutually closed. The channel upper part 2 is at the upper end sides of the support lever 9 $ dio by corresponding recesses in the bottom flap. 6

Approximately vertically below the longitudinal axis of the expiring semi-finished product 10 is the pivot point 11, _o in which the support lever 9 are mounted in the gutter stand 1. The vertical position of the pivot point 11 of the support lever 9 in the gutter stand 1 was chosen so that this together with the longitudinal axes of two semifinished rods 10 theoretically gedachte, simultaneous contact with the wear surfaces 12 in the right chamber 5 and in the left chamber 4 form an equilateral triangle ; so that the center distance of the semifinished product from the left chamber 4 to the right chamber 5 when touching the wear surfaces 12 approximately corresponds to the distance of each semi-finished longitudinal axis to the pivot point 11. Simultaneous occupancy of both chambers 4; 5, however, does not occur in practice, since only one semifinished product bar loads the processing machine upstream of the outlet channel and enters the chamber located in the upper pivot position. To open and close the bottom flap 6 are arranged on the support levers 9 working cylinder 13 »and for pivoting the entire gutter shell 2, the working cylinder 14, which are located in the gutter stand 1 and are hinged to the lower lever arms of the support lever 9. Not shown in the drawing, the adjustability of the outlet channel to adjust it in height and tilt the direction of the expiring semi-finished product 10.
