Machine de cadre & étrier ( cadreuse automatique )

It furthermore comprises a cutting device, one of the blades 7 of which is located in a recess 5 of the circular mandrel 1the said recess 5 being located near the point 6 where the reinforcing bar 4 comes into contact with the mandrel 1 at the start of the bending process.

Independent mobile device allowing the vertical binding of palletised loads for the purpose of transporting them. Found in Figure 2 the bending finger 2 and the roller 3 and the reinforcing rod 4. We know that the realization of reinforced concrete structures require reinforcement shape and varied dimensions that are most often constituted by longitudinal elements bent hairpin at their ends and interconnected by wire also made frameworks folded steel. It is seen in Figures 3 and 4 a straightening-forming machine according to the invention comprising a straightening 10 provided with feed rollers 11 to push the concrete bar 4 from the coils 9 blockers between rollers 12 and 13 arranged in planes perpendicular.

The trainer 10 then advances the concrete bar 4 of a length corresponding to one side of the frame and the folding roller 3 performs the folding of the reinforcing rod 4 and so on until the formation of the different sides of the frame. The present invention also aims to provide a single machine which, by the combination of its elements, allows to achieve neton the longitudinal elements and the reinforcement cardeuse that meet them.

As a result, without making any movement back and forth on the concrete bar 4, we can choose a short length as desired for the end of the reinforcing rod which constitutes the pin beyond the last fold. There is shown in Figure 2 a second embodiment of the folder-sectionneuse according to the invention which corresponds to bending over a mandrel caxreuse of smaller diameter. In betkn way, the reinforcing rod 4 which is drawn when it enters the shaper.

Machine de cadre & étrier ( cadreuse automatique ) –

Pipe conduit bending machine and method of making a pipe conduit with a soldered joint. In this embodiment, the fixed blade 7 of the shears is integral with the mandrel 1, while the movable blade 8 cuts the reinforcing rod 4 which is supported on the blade 7, which is supported by the chuck 1 which is integral the frame of the machine.

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 shear stress between the two blades 7 and 8 is constructed in the known manner, for example by means of a hydraulic or pneumatic cylinder.

The present invention relates to a folder-sectionneuse to achieve particular round frames concrete and universal trainer-forming machine using this folder-sectionneuse to achieve concrete round frames and the use of the latter for the manufacture of armatures.

To realize the longitudinal elements of the armatures, the straightening machine 10 is placed in the up position with the cylinder Of course, the shears of the folder-sectionneuse is not used on this occasion.

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.

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 In this position, it sends in the chute 14 to a predetermined length of round upright concrete which is conventionally sectioned in e.

Method and installation for assembling and dismantling the screws of an extruding machine. In particular, 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. When the frame is thus made the reinforcing rod 4 is advanced depending on the length of the pin that is desired and by moving the 7,8 of the shear blades to sever reinforcing bars, the liberating cadreusse of the trainer.

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 beeton 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. To achieve the frames, the straightening machine 10 is brought into the low position by acting on the 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.

Machine and working cycle for making plastic bags with a zip fastener and device for positioning them. The present invention relates to a folder-sectionneuse for producing reinforcement frames for concrete reinforcing bars, of the type wherein a pin provided with a roller pivoted to an adjustable angle around a circular mandrel for bending round to concrete around the latter, characterized.

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.

Is schematically shown in Figure 1 a first embodiment of a folder-sectionneuse according to the invention. The various movements of the various parts of the machine which has just been described can be controlled by a microcomputer, in particular, the lengths of the different concrete round sections which are cut by the straightening, the position of the folder-sectionneuse and that of the bending head and the bending angles of each.

A1 Designated state s: 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.

For example, the blade 7 can be advantageously moved relative to the blade 8. According to the present technique, the cadreue 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. The trainer 10 then sends the folder-sectionneuse 16 a round length in concrete 4 such that the latter exceeds the brake 16 sufficiently to make a hook which is obtained by pivoting of the folding roller 3 Fig cadresue and 2.
