Definitions
- Wire bending machine combining a sequential forming device and a device involving a tool plate.
- the present invention relates to a new concept of wire bending machine and its control methods.
- wire bending machines There are two major types of wire bending machines.
- a first type of machine works in a sequential manner, folds after folds, using standard tools simple and economic, for example tools called “spinning", possibly with a device for rotating the wire to make folds in different planes.
- This type of machine is ideal for shaping small series of parts, in terms of the quality of the shaping and in terms of profitability and cost per piece.
- patent application EP 0 865 842 describes a machine for sequential shaping with two folding heads, these two heads can not work simultaneously the same part, and a transfer using a gripper is always necessary to change the head and make a plane shaping.
- This machine has the drawbacks mentioned above, namely that it is only suitable for productions with low speeds.
- a machine for sequential forming requires a control method capable of programming a geometry.
- a second type of automatic folding machine is used to shape a multi-ply piece on a tool plate whose tools are operated in masked time to increase productivity and work at high speed.
- it is a wire bending machine and its driving method which is a method capable of programming the movements of the actuators.
- Such a machine because of its cost, is suitable for shaping parts in large series.
- the machines mentioned above do not offer an optimum profitability for the shaping of medium series of parts, in fact the sequential machine works at a too slow rate, and the machine tool plate represents an investment important. In both cases, the incidence is a cost per part that is not optimized for an average series production.
- a production requires a rate of a few pieces per minute, for example from 2 to 3 pieces per minute
- the manufacturer is preferably equipped with a machine of sequential type, and if the production of a similar piece requires a high rate, for example 30 to 60 pieces per minute, it is equipped with a machine table tooling.
- a high rate for example 30 to 60 pieces per minute
- it is equipped with a machine table tooling.
- he has to produce a part at an intermediate rate, for example 10 to 12 pieces per minute or even 8 to 30 pieces per minute, he does not have in the prior art at his disposal machines meeting his request. for optimum costs.
- the invention consists of a machine for the automatic shaping of workpieces by different folds made in the same plane or in different planes, characterized in that it comprises in combination a first device for performing a sequential shaping with standard tools folded by fold and a second device implementing a tooling plate, the two devices being managed by a single digital control capable of programming both a geometry and actuator movements for a mean rate.
- the machine is characterized in that the first device comprises at least one spinner and / or in that it furthermore comprises at least one rotating gripper and / or the tooling plate that can be mounted and actuated in a machine. plan different from the shaping plane of the first device, and further comprises a transfer device adapted to the change of plan.
- control method is characterized in that the numerical control provides the possibility of making a blank of a folded part by fold on the first device and then transferring the workpiece to the second device so as to complete the part, and / or the numerical control provides the possibility of shaping a part of the workpiece on the first device and shaping the remaining part or parts on the second device, and / or the numerical control provides the possibility of using each machine alone, and / or the numerical control provides the possibility of implementing the two machines to achieve the same piece.
- FIGS. 1 and 2 show schematically in front view and in sectional view along AA a machine according to a non-limiting variant of the invention.
- the machine shown in the figures is a combination of a sequential forming machine (1) and a table-forming machine equipped with a tooling plate (2) as described in patent EP 0 301 972 cited in introduction.
- the sequential machine (1) comprises standard tools, for example spinches (3.4) movable along two axes (x) and (y) for making folds in a plane (x, y). , and possibly a rotating gripper (5) when the profile of the part requires a fold in a direction inclined relative to the plane (x, y).
- the second machine has a table (6) equipped with a tool plate (7) each tool being independently movable and mechanically driven by tie rod systems such as (8) ) and not shown in detail in these figures, each controlled by a predetermined program of a digital control (9).
- this set of tools makes it possible to produce complex parts and / or high-speed parts.
- the tooling plate (7) is positioned in the working plane (x, y) of the first machine, and the same device wire advance can directly transfer the wire from the first to the second machine, in this case there is therefore removal of a transfer means.
- the same numerical control manages the tools of the two machines, it is therefore able to program both a geometry and the actuators of the plate which allows to combine the programming steps.
- the combination of the two machines therefore has the advantage of facilitating the transfer of parts and synchronizing the movements of the tools of the two machines, this synchronization being essential to reduce costs and optimize production and to allow a single rate of processing on both machines when the shaping steps are spread over the two machines.
- the workflow of a workpiece can be carried out according to several programming combinations that are chosen according to the complexity of the profile to be obtained, the investment in specific tools or the desired rate:
- On tooling plate and a specific part (on spinning wheel for example), a part whose definition is not completely fixed on a part or evolution of a piece initially provided on a tool plate.
- a machine according to the invention has a great flexibility of use and can meet all the industrial needs of wire shaping with the best optimization cost / rate and / or cost / complexity of shaping, and this even for average rates , which was not possible before.
- the piece can be cut after the first shaping, after the transfer between the two machines or after the second shaping; a first forming on the first machine can be performed on a part, while the final shaping of the previous part is done on the second machine which increases productivity.
- a machine of this type comprises active means, a work plate, a tool plate, tie rods and tools, the autonomous active means of which, independent and secured to the work plate, actuate levers connected by tie rods to the tools. mounted on the tool plate, the active means being mounted on a common translation means via a disengageable means, said active means (60,61,62,63) being driven by brushless electric motors (70) by means of ball screws, and the levers (50,51,52,53) for actuating the tools (21,22,23,24,25) being connected to the tie rods (30,31,32 , 33) by connections (40,41,42,43) by one of their ends (513) and, by translation means, by the other end (511).
- a machine of this type is characterized in that the common translation means (45) of the active means (60, 61, 62, 63) is a rotating screw (45) driven by a motor (90): the disengageable means being half-nuts engaged on the same screw.
- a machine of this type is characterized in that the active means (60,61,62,63) are, in the disengaged position, fixed to the work plate (1).
- its driving method is characterized in that, after studying the movements of tools, the coordinates of the connection points are introduced, the characteristics of the active means are memorized (60, 61, 62, 63) and in that the processing unit calculates the theoretical starting points of the motors so that the tools work in masked time.
- said method takes into account the inertia of the system to determine the actual starting points.
- the processing unit calculates the displacements of the connection points when modifying the characteristics of the active means (60,61,62,63) and / or one of the values of the coordinates of the connection points .
- the beginnings and the ends of feeding coincide with the beginnings and the ends of cycles.
