Profiling machine for finished or semi-finished prods. Wire pay-off station for wild spooled coils Machine It is understood that the embodiments which have been described above presents no limiting and can receive any desirable modifications without departing from the scope of the invention. We know that the realization of reinforced concrete structures require reinforcement shape and varied dimensions that are most often constituted by bfton elements bent hairpin at their ends and interconnected by wire also made frameworks folded steel.

The straightening-forming machine according to the invention first of all allows to realize the longitudinal elements of the reinforcement of reinforced concrete by sending into the trough, a round section with concrete prepared of predetermined length, whereupon this section falls on the folding table including the bending head and the folder-sectionneuse which are placed near the ends of the concrete round section ensures the folding of the ends thereof and carrying pins.

In this way, thanks to the actuator 22, it is possible to tilt the straightening machine 10 about its hinge axis 21 between two positions, namely a high position in which the reinforcing rod 4 comes out of the straightening machine 10 is in the axis of the chute 14 and a low position in which the reinforcing rod 4 comes out of the straightening machine 10 is located in front of the bending head 17 as shown by 4 in Figure 5.

According to the invention, the straightener 10 is mounted on a support 20 hinged in 21 on the frame of the machine while an actuator 22 is hinged at 23 on the machine frame and at 24 on the support 20 of the straightening According to the present technique, the longitudinal members are made using a straightening machine that sends a predetermined length of yarn into a chute which discharges on a folding table which folds in the pin ends of the elongate elements.

It is seen that the invention allows a simple way to achieve effective universal manchine who can perform all the necessary parts to obtain reinforcements for reinforced concrete. Pipe conduit bending machine and method of making a pipe conduit with a soldered joint. VTLS Chameleon iPortal Format complet The various movements of the various parts of the machine which has just been described can be controlled by a microcomputer, careuse particular, the lengths of the different concrete round sections which are cut casreuse the straightening, the position of the folder-sectionneuse and that of the bending head and the bending angles of each.

The present invention aims to achieve a folder-sectionneuse which allows to cut reinforcing bars in the immediate Neighborhood, its last fold without having to communicate movements back and forth. Is schematically shown in Figure 1 a first embodiment of a folder-sectionneuse according to the invention. In the embodiment of Figure 1 corresponding to the relatively large diameter of bends, the two plates 6 and 7 of the cutter may be operated independently of the mandrel 1 which undergoes accordingly none of the efforts due to shear.

There is shown in Figure 2 a second embodiment of the folder-sectionneuse according to the invention which corresponds to bending over a mandrel 1 of smaller diameter. It is seen that in both embodiments, the reinforcing rod 4 can be cut in the very near the point 6 point that is one from which concrete 4 to the round starts to be folded on itself.

The machine just described operates in the following manner. Similarly, the bending head 17 may be secured in a fixed position. Method and installation for assembling and dismantling the screws of an extruding machine.

Kind code of ref document: Sur ce dessin, On this drawing. The present invention relates to a folder-sectionneuse to cadreues particular round frames concrete and universal trainer-forming machine using this folder-sectionneuse to achieve concrete round frames and the betpn of the latter for the manufacture of armatures. The trainer-forming machine according to the invention also makes it easy to achieve even small frames thanks to the fact that the folder-sectionneuse which is close to the trainer allows to cut reinforcing bars near the last bend without communicate a back and forth.

The present invention also aims to provide a single machine which, by the combination of its elements, allows to achieve both the longitudinal elements and the reinforcement frames that meet them. This results in lower cost, universal machine that can perform all types of reinforcement. With a cadreusse of known type, for example by tilting the chute 14 discharges the concrete 4 round section standing on the folding table 15, the folder-sectionneuse 16 and 17 fold the head have been previously brought into position fet depend on the length of the concrete round section 4.

Otherwise, it is advantageous to secure the fixed blade of the shears with circular mandrel which thus absorbs the shearing forces generated by the movable blade that is located on the other side of the reinforcing rod.

According to the invention, the mandrel 1 comprises a recess 5 in the vicinity of the point 6 where the reinforcing rod 4 comes into contact at the beginning of the folding process. To achieve the frames, the straightening machine 10 is brought into the low position by acting on cadreusr cylinder 22 while the folder-sectionneuse 16 is returned to the right. It is seen from Figure 6 which is a view on a larger scale in section on VI-VI of Figure 4 the straightening machine 10 and the driving rollers 11 which receive reinforcing bars straightening 4.

For example, the blade 7 can be advantageously moved relative to the blade 8. Found in Figure 2 the bending finger 2 and the roller 3 and the reinforcing rod 4.

In x, it is clear that the displacement of the straightening between the high and low position can be achieved in a different way than has been shown in Figure 4. Wire pay-off station for wild spooled coils Cadreue shown in this figure, the bending head 17, which is constituted by a mandrel 18 against which abuts a concrete bar 4 which is pressed by a movable finger 19 which is provided with a not shown roller and which can be rotated around the mandrel 18 by a predetermined angle to make the concrete round the folding around the mandrel 4.

According to the invention, the movable blade of the shears is appropriately set in the recess of the mandrel when the latter has a sufficient size.

It is understood that the reinforcing rod 4 is held in position by its right side, is caused to wrap around the mandrel 1 when the folding finger 2 and roller 3 is displaced in the direction of arrow F by pivoting about the axis of the mandrel 1. This folder-sectionneuse comprises in known manner a circular folding mandrel 1 and a folding finger 2 which is provided at its end with a roller 3 which can be pivoted about the axis of the mandrel 1.

The invention also relates to methods of use of the straightening-forming machine defined above. According to the invention, the latter comprises a chute 14 disposed above a folding table 15, which comprises, firstly, a folder-sectionneuse 16 according to the invention of the type represents- in Figures 1 and 2 and secondly a bending head Of course, the shears of the folder-sectionneuse is not used veton this occasion.
