Description

TECHNICAL AREA

The present invention relates to the technical field of steel sheet processing, specifically a clamping device for a leg of an H profile steel.

STATE OF THE ART

H-section steel is a highly efficient section material with an economically designed cross-section, characterized by optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Its name derives from its cross-section, which has the shape of the English letter "H"; Since the individual points are arranged at right angles in an H-section steel, the H-section steel is advantageously characterized by high bending resistance in all directions, good construction friendliness, saved costs and low structural weight and is already widely used.

An H section steel consists of two leg strips and a web strip that are assembled together. The positional relationship of the legs and the web relative to each other directly affects the good part rate of the finished H-section steel product. The conventional pre-assembly of legs and web is such that a web strip is brought into a horizontal position by a fitter using a simple device and then dragged to the middle of a leg strip, after which pre-welding takes place. Such pre-welding is primitive and rough, and has poor welding accuracy. Furthermore, the web strip is laborious for assemblers to move and turn over, resulting in low production efficiency.

Accordingly, improvement is required in view of the above technical problem.

1. 1. Bei der Klemmvorrichtung für einen Schenkel eines H-Profilstahls nach der vorliegenden Erfindung wird während der Förderung eines Stahlbleches ein Schenkel durch den Klemmmechanismus geklemmt und bewegt, womit neben einfachem Aufbau und praktischer Anwendbarkeit der Arbeitsaufwand für Monteur beim Bewegen und Umdrehen verringert und die Produktionseffizienz erhöht wird;
2. 2. Bei der vorliegenden Erfindung ist zwischen der Elektromotor-Bodenplatte und dem Fixierblock der Drehmomentbegrenzer angeordnet, der mit dem Klemmmechanismus zusammenwirkt. Bei dem Drehmomentbegrenzer handelt es sich um eine Überlastschutzvorrichtung, wobei ein durch ein Antriebssystem übertragenes Drehmoment begrenzt wird, indem durch Einstellen eines Anfangswerts des Gewichts eines geklemmten Stahlbleches die Klemmmechanismen an der Leitspindel mit Rechts- und Linksgewinde aufeinander zu/ab gleitet, somit eine Beschädigung der Vorrichtung verhindert wird;
3. 3. Bei der vorliegenden Erfindung ist eine Verbindungswelle vorgesehen, auf der die Drehhülse aufgeschoben ist. Ein zu klemmendes Stahlblech wird durch eine Fördervorrichtung auf die Drehhülse auf der Verbindungswelle gefördert. Die Drehhülse sorgt für stabile Platzierung des Stahlbleches und erleichtert das spätere Klemmen des Stahlbleches, womit die Stabilität und die Günstigkeit beim Klemmen des Stahlbleches erhöht werden;
4. 4. Bei der vorliegenden Erfindung ist der Abstand zwischen der Drehhülse und der radialen Basis größer als der Abstand zwischen der Leitspindel mit Rechts- und Linksgewinde und der radialen Basis; Die obere Abschlussfläche der Drehhülse liegt auf ein und derselben horizontalen Ebene wie die obere Abschlussfläche der Leitspindelmutter und korrespondiert mit der Position des Klemmmechanismus. Somit wird die Klemmgenauigkeit des Schenkels erhöht und das Stoßen des Schenkels beim Klemmen gegen die Leitspindelmutter vermieden und zudem werden die Stabilität und die Sicherheit beim Klemmen der Stahlbleches erhöht;
5. 5. Bei der vorliegenden Erfindung wird der Schenkel durch den Klemmmechanismus geklemmt, womit die Sicherheit und die Stabilität beim Klemmen des Schenkels erhöht werden. Des Weiteren wird der Arbeitsaufwand für Monteur beim Bewegen und Umdrehen verringert und die Produktionseffizienz erhöht;
6. 6. Bei der vorliegenden Erfindung ist das Klemmrad als sich von oben nach unten verjüngende kegelförmige Struktur ausgebildet, womit beim Klemmen des Schenkels das Beobachten von einem Monteur erleichtert wird, ob der Schenkel bereits fixiert ist, Zudem wird der Bedienkomfort verbessert;
7. 7. Bei der vorliegenden Erfindung ist außen am obersten Bereich des Klemmrades eine horizontal erstreckende Platte fest angeordnet, die zur Anlage mit der oberen Endefläche des Schenkels beim Klemmen, Bewegen und Umdrehen kommen kann, womit die Verwendungssicherheit sichergestellt wird;
8. 8. Die horizontal erstreckende Platte ist mit dem Klemmrad fest verbunden und einteilig ausgeformt. Somit werden die strukturelle Festigkeit und Robustheit des Klemmrades verbessert, was wiederum für erhöhte Festigkeit und Robustheit der ganzen Vorrichtung sorgt.

In the clamp device for a leg of an H-section steel according to the present invention, a leg is clamped and moved by the clamping mechanism during the conveyance of a steel sheet, which, in addition to simple structure and practicality, reduces the labor for assemblers in moving and turning and the production efficiency is increased;
2. 2. In the present invention, the torque limiter, which cooperates with the clamping mechanism, is arranged between the electric motor base plate and the fixing block. The torque limiter is an overload protection device in which a torque transmitted by a drive system is limited by sliding the clamp mechanisms on the right-hand and left-hand thread lead screw toward/down from each other by setting an initial value of the weight of a clamped steel sheet, thereby preventing damage to the device is prevented;
3. 3. In the present invention, a connecting shaft is provided on which the rotary sleeve is slid.

In the present invention, the distance between the rotary sleeve and the radial base is larger than the distance between the right and left-handed lead screw and the radial base; The upper end surface of the rotating sleeve lies on the same horizontal plane as the upper end surface of the lead screw nut and corresponds to the position of the clamping mechanism. Thus, the clamping accuracy of the leg is increased and the abutment of the leg against the lead screw nut is avoided when the leg is clamped, and the stability and safety when the steel sheet is clamped are also increased;
5. 5. In the present invention, the leg is clamped by the clamping mechanism, thus increasing the safety and stability of leg clamping. Furthermore, the labor for assemblers in moving and turning is reduced and the production efficiency is increased;

Furthermore, the labor for assemblers when moving and turning is reduced and the production efficiency is increased.

The pinch wheel 202 is formed as a conical structure tapering from top to bottom; The pinch wheel 202 includes an inclined surface 207; The angle of inclination between the inclined surface 207 and the rotary sleeve 27 is 30° to 60°; Specifically, the angle of inclination between the inclined surface 207 and the rotary sleeve 27 is 45°. In the present invention, the clamping wheel is designed as a conical structure that tapers from top to bottom, which makes it easier for a fitter to observe when clamping the leg whether the leg is already fixed. In addition, ease of use is improved.

The height of the pinch wheel 202 is matched to the thickness of the leg. Thus, the convenience of clamping is improved. On the outside of the uppermost portion of the clamp wheel 202, a horizontally extending plate 206 is fixed, which can abut with the upper end surface of the leg during clamping, moving and turning, thus ensuring the safety of use.

The horizontally extending plate 206 is fixed to the pinch wheel 202 and is formed in one piece. Thus, the structural strength and sturdiness of the pinch wheel is improved, which in turn provides increased strength and sturdiness of the entire device.
