BRIEF DESCRIPTION OF THE DRAWINGS Further features and advantages of the present invention will become apparent from the following detailed description. The embodiments described below with reference to the accompanying drawings are merely examples, and the present invention is not limited thereto.

An apparatus for shaping and cutting bar-shaped elements, in particular rebars, according to the invention comprises a first supply assembly 2 for supplying a bar 4 and a second supply assembly 3, generally referenced. It has a support frame indicated by the reference numeral 1.

The first supply assembly 2 is arranged so as to protrude with respect to the frame, so that the movable bar magazine 5 can be used. Magazine 5 can quickly replace and replenish raw materials during processing,
There is no need for positioning time for the rod bundle with the conventional solution.

Downstream of the bar 4 supply assembly is a cutting assembly 7 that can cut the bar to a selected length.

A cutting assembly 7 is located between the second supply assembly 3 and the bending head 10, which bending head is positioned substantially axially with the supply line formed by the supply assemblies 2 and 3. It comprises a bending assembly 11 that can be placed in a first position to be mated.

In the first position, a bent bar 4
A table 12 for supporting the table is provided.

The bending assembly 11 can be located at a second location remote from the supply line. The second position is below the supply line in the illustrated example, and is provided with a plurality of support rollers 20 and an abutment collet 21 for holding a bar. After the bending by the bending assembly in the first position is performed, the bar is released by opening the bottom of the table 12 so that the bar can fall on the roller 20 and bend its second part. Become like

Below the roller 20, there is provided a partitioned moving platform 30, which can be selectively moved to accommodate the bent bar according to a predetermined pattern. As a result, the same set of bars and shaped parts is obtained. Each bar and part belongs to the same element (beam, pillar, column, etc.) but has various dimensions and diameters.

The second position where the bending assembly may be located may be selectively an upper region. Also, there may be two separate bending assemblies located at two different locations. A first bending assembly on a supply line formed by the supply assemblies 2 and 3;
And a second bending assembly spaced from the bending assembly.

In actual operation, the supply assemblies 2 and 3 draw in the bar 4 and supply the bar to the bending assembly 11 located in the first position, the desired bend in the front part of the bar 4. Is formed.

The bar 4 is drawn by suitable elements and the table 12 is dimensioned to support the weight of the bar.
Supplied to

Once the required bends have been made, the apparatus continues to pull in and measure the bar 4 until the linear dimensions of the finished part are reached.

In the final part of the operation, the bending assembly 11 moves to a second position. In the second position, the second
Bend, or more precisely, at the other end of the selected bar portion.

After the measurement of the bar 4, the bar 4 is cut by the cutting assembly 7, and the movable bottom of the table 12 is opened. Then, the semi-finished part falls onto the roller 20 arranged at a lower position. The bending assembly 11 is already located there.

At this point, the operator retracts or advances the semi-finished product by hand or a suitable automatic feeding assembly to the extent appropriate for the position of the bending assembly 11 and performs any remaining bending on the rear of the bar element. Do.

To facilitate movement of the bar 4 by hand,
There may be standards such as graduated bars or locators that can be adjusted manually or by a motorized actuation mechanism.

When the operator gives a command to continue the manufacturing cycle, the abutment collet 21 acts as an abutment during the bending operation and has the dual purpose of preventing movement of the part being machined. Grab the completed part.

During this time, the bending head 10 reaches the correct position and applies a bending to the rear of the bar-shaped element.

If there is more than one rear bend, these steps are repeated continuously until processing is complete.

When the required bending operation is completed, the apparatus drops the bent bar into the appropriate compartment of the mobile platform 30. The shaped elements and bars of different diameters and dimensions, which make up the individual parts, are thus selectively accommodated in each compartment according to a preset sequence.

To reduce waste, a welding station may be located upstream of the first supply assembly. The welding station performs butt welding automatically or semi-automatically, so that a bar of virtually infinite length can be supplied.

Further, in order to reduce waste, it is possible to set a processing cycle for manufacturing products having different dimensions from the same bar. That is, it is possible to combine different batches of parts to be manufactured or optimize the dimensional fit of the manufactured product.

From the above description, it is apparent that the present invention achieves its intended purpose and objects. In particular, an apparatus is provided in which rod-shaped rods can be processed with a minimum of waste in a substantially automatic procedure and reliably using readily available and much cheaper available primary products.

The invention thus conceived can undergo many modifications and variations, all of which are within the scope of the invention. All of the above details can be replaced with other technically equivalent elements. In fact,
The materials used may be any as long as the requirements are met, as well as the associated shapes and dimensions.
