Description
Technical field
The present invention relates to the panel beating field, relate in particular to a kind of folding arc device for metal blank folding circular arc.
Background technology
Panel beating is for a kind of comprehensive cold machining process of sheet metal (usually below 6mm), comprises cutting, rushing/cut/compound, folding, welding, riveted joint, splicing, moulding (such as body of a motor car) etc.Its significant feature is exactly the Same Part consistency of thickness.In the metal blank process engineering of reality, usually according to building or structural requirement, need to be with the bending of sheet metal plate.
In the metal blank bending technique, comparatively special with metal blank folding circular arc technique again.In this technique, require sheet metal is bent into arc surface, and require cambered surface smooth, and plate surface is stressed evenly, the bending position accurate positioning, and the panel surface behind the folding circular arc is level and smooth, not fragile.
In the prior art, the difficult point of above-mentioned metal blank folding circular arc technique is the crooked place location difficulty.In the existing technique, the general technology workman is by some instruments, finish the location work of metal blank, positioning requirements compared to sheet metal is passed through the positioning of tool method like this because multiple artificial operation factors, obviously can't reach the workpiece that processes and bend the size angle always, and because skilled worker's application of force is uneven, by comparatively serious to the damage of material surface in processing folding circular arc process, and manually-operated production efficiency can not be guaranteed.
It is worth mentioning that, also can use large-scale bending equipment in the actual production, this equipment precision is high, and mechanically actuated avoided manually-operated to cause the asymmetric problem of processing work, and operating efficiency has obtained lifting by a relatively large margin.But such equipment cost that is equipment own also or the processing technology cost is all higher, obviously is not suitable for the production and processing of medium-sized and small enterprises.
In view of this, should provide a kind of does not increase production cost when can guarantee the circular arc quality, and can increase substantially the folding circular arc device of production efficiency.
Summary of the invention
The purpose of this invention is to provide does not a kind ofly increase production cost when can guarantee the circular arc quality, and can increase substantially the folding arc device of production efficiency.
According to an aspect of the present invention, provide a kind of folding arc device.Device comprises pedestal and is arranged at cylinder on the pedestal, presses frame and tight lock part; Press frame and pedestal to join, press the support body of frame and pedestal junction to be defined as rotating shaft, pressing frame can rotating shaft be the axle center upset; Tight lock part is arranged in the described rotating shaft, and tight lock part can support and be located in the rotating shaft, and pedestal one side convexes with connecting portion, presses frame to be connected and fixed by connecting portion and pedestal, and connecting portion comprises the connector of two symmetries, and the connector surface offers the first through hole.The connector surface offers the first through hole, and the size of the first through hole and pressure frame support body consistent size in assembling process, are pressed frame can pass the first through hole, and fixed and be limited in connecting portion.
In some embodiments, tight lock part comprises clamping screw, lock nut and catch, and clamping screw bolt head passes rotating shaft.In the assembling process, successively lock nut and catch are arranged on the clamping screw, the clamping screw that will be equipped with again locking nut and catch passes the second screw and is arranged in the rotating shaft, screw at last locking nut and make it be pressed on the catch surface, thereby so that clamping screw fix.
In some embodiments, press frame to comprise and press the frame body and be arranged at the depression bar of pressing on the frame body, pressing the frame body is frame structure, presses the frame body surface to form the room, and the shape and size in room are all corresponding with the shape and size of cylinder.In process, press frame to overturn take rotating shaft as the axle center, when pressing frame to turn near the cylinder place, then cylinder can pass the room, makes the pressure frame can continue upset and fits as for seat surface.
Compared to prior art, useful technique effect of the present invention is that metal blank to be processed and drum surface are fitted naturally, on the one hand can be so that the bending location be more accurate, and the arc surface that forms is evenly level and smooth, and can be to metal blank surface injury; On the other hand, above-mentioned molding mode of naturally fitting with cylinder also can guarantee a plurality of arc surface consistent size, and simple frame for movement and operation have also improved production efficiency greatly, have reduced manufacturing cost.
